CLSRSC-188: Failed to create keys in Oracle Local Registry

Posted by FatDBA on January 3, 2020

Hi Everyone,

Happy New Year!

So here goes my first post for Year 2020. This time I will be discussing an error that we encountered some time back while executing the important ‘root.sh’ script for a new 12cR2 Oracle Restart setup on RHEL7. The script was going smooth till the point where it tries to add keys in OLR for HASD and died with error “CLSRSC-188: Failed to create keys in Oracle Local Registry”.

Below is the exact error what we get during the root.sh run.
Here you will that it was throwing an error which says “Site name (1819181-monkeydb) is invalid.clscfg”.


[root@1819181-monkeydb gridhome]# ./root.sh

It all happened because our hostname started with a number (1819181-monkeydb) and it’s a known bug that makes the hostname as invalid for root.sh and therefore the above error comes up.
There is a another condition as well, suppose your hostname starts with a alphabet (AHOST-TEXTIBOX-09) but as there is a limit of 15 characters which oracle considers for the hostname, and here in our example the 15th character is a hyphen (-).
So, even in such a case the root.sh will fail even when the hostname starts with a non-numeric character but it’s 15th character is a special character.

Now let’s discuss the solutions.
First, you can apply a merge patch 26751067 (which is merge of Bugs: Bug 25499276 Bug 26581118) and re-run the root.sh script.
Second, change the hostname right after the failure and re-run the script, this time it will go through with no error. Below is an example.

Let’s first change the hostname quickly before we and re-run root.sh


[root@1819181-monkeydb gridhome]# cat /etc/hostname
1819181-monkeydb
[root@1819181-monkeydb gridhome]# echo A1819181-monkeydb > /etc/hostname
[root@1819181-monkeydb gridhome]# cat /etc/hostname
A1819181-monkeydb
 

To update your command prompt simply re-login and to apply this change system wide execute below.


[root@1819181-monkeydb gridhome]# systemctl restart systemd-hostnamed
[root@A1819181-monkeydb gridhome]#

FGA Error ORA-28138: Error in Policy Predicate

Posted by FatDBA on December 26, 2019

Hi Folks,

Today’s I am going to discuss one of the eerie issue that we faced recently while doing a Database Switch-over activity (From 10gR2 to 12cR2) where application team changed their application string or connection ways and started pointing to this new 12c database.
Before I proceed, let me give you a quick background about this activity, this was a test (Staging) database which was migrated on a new infrastructure and with version 12c, we’ve used data pump to move data from source to this new target and everything went well during all those steps.

Everything was successfully moved till the time the first test customer login to the application and reported that he failed to connect using his credentials. One error message that was captured in application server logs (this was a three tiered platform) which reads

"java.sql.SQLException: ORA-28138: Error in Policy Predicate". 

This error prevented all of the users to connect with the application after this switch-over. Well, apart from regular login procedures, rest all of was working fine.
The error immediately gave us an idea that the error was pointing to the FGA that we have tested on few of the tables some time back, including one of the base table which is used to insert login details before it authenticates access. So, we verified the FGA settings that migrated to this new database and found they are configured with some strange and complex AUDIT conditions
using a custom function where someone tried to define a subquery in the audit_condition, and didn’t tested the result.


i.e. sys.check_audited_user > 0  & sys.check_audited_user = 'XYS'. 

This being an invalid policy preicate and ultimately all operations got failed on said table which in turn stopping users to login.
So, this all happened due to complex precidates used in audit policies, this should be avoided. I mean it will allow you to create the policy but will fail with such errors related with FGA predicates. You cannot define a subquery in the audit_condition; it must be a simple predicate

So, now we have two solutions to avoid this situation.
One, you can simply go and drop the policy created on the said object to resume operations.
Else you can write a function that will evaluate the complex criteria and return a value that can be used in a simple predicate.

RAT Reporting Error: ORA-06502: numeric or value error: character string buffer too small

Posted by FatDBA on December 16, 2019

Hi All,

Today’s topic of discussion is to handle/fix one of the issues that I’d faced while generating RAT (real application testing) reports on 10gR2 database. I know many of us are not yet aware about the tool, it’s purpose and functionality. Very soon I will be writing about this great product from Oracle for database load testing using real/genuine workload and is quite helpful to forecast your DB performance before you migrate.

Alright, coming back to the point – I was trying to generate the RAT Capture report (on target of course) to see what all was there in the capture, its observations, highlights and rest and that’s when we’ve encountered an error (pasted below)



DECLARE
l_report CLOB;
BEGIN
l_report := DBMS_WORKLOAD_CAPTURE.report(capture_id => 81,
format => DBMS_WORKLOAD_CAPTURE.TYPE_HTML);
END;
/ 2 3 4 5 6 7
DECLARE
*
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "SYS.DBMS_SWRF_REPORT_INTERNAL", line 7446
ORA-06512: at "SYS.DBMS_SWRF_REPORT_INTERNAL", line 8591
ORA-06512: at "SYS.DBMS_SWRF_REPORT_INTERNAL", line 8521
ORA-06512: at "SYS.DBMS_WORKLOAD_CAPTURE", line 486
ORA-06512: at "SYS.DBMS_WORKLOAD_CAPTURE", line 1214
ORA-06512: at line 4


There are two solutions to this problem:

1. First to drop the common (shared by capture and replay) schemas and their infrastructure tables using below two scripts.
That firstscript below drop schema tables shared by capture and replay and second drops the Capture infrastructure tables.
catwrr.sql – Catalog script for Workload Capture and Replay — this script then rebuilds all the capture and replay related tables.


@@?/rdbms/admin/catnowrr.sql
@@?/rdbms/admin/catwrr.sql
exec prvt_report_registry.register_clients(TRUE); --- This one registers clients 

Note: In that case you might loss all of your previous capture ID details from the system as it simply washes or wipes everything there related with RAT tables. Hence this is kind of a crude and a raw method to fix this issue. And I recommend to always connect with Oracle Support before going to run these scripts on your database!

2. I tried of another approach to avoid this error and generate the RAT capture report from the target instead of Source where we were getting the error.
Is that possible ?? — Yes, you can. After further analysis I found the issue is with the 10gR2 capture reporting code which sometimes throws this error.

So, the second way turned ut to be a better approach here as we have all of our previous stats and data untouched and nothing has been wiped out in this case, as we simply ran the reporting procedure from the target (12c R2 in our case) and that’s how avoided the issue.

root.sh failed on RHEL >7.3 — CLSRSC-400: A system reboot is required to continue installing,

Posted by FatDBA on November 14, 2019

Hi Everyone,

Was little occupied in few of the database migrations happened here at my end, so wasn’t able to post on regular basis. But the good thing is that I have a good list of issues that we faced during the course of this end of end migration and starting from today will try to share all them.

Alright, the one I am going to discuss next is the issue that we encountered while running root.sh script on this ‘Oracle Restart’ setup where the root.sh script failed with below set of errors



Creating /etc/oratab file...
Entries will be added to the /etc/oratab file as needed by

The command '/u01/app/12.2.0.1/grid_home/perl/bin/perl -I/u01/app/12.2.0.1/grid_home/perl/lib -I/u01/app/12.2.0.1/grid_home/crs/install /u01/app/12.2.0.1/grid_home/crs/install/roothas.pl ' execution failed 


To further understand what caused that failure we have checked the log file the above error pointing.
Below are few of the core/main lines when it got failed. So it shows that it failed to load the ADVM/ACFS drivers on the system while running the root.sh script.



>  ACFS-9504: Copying file '/u01/app/12.2.0.1/grid_home/lib/libacfs12.so' to the path '/opt/oracle/extapi/64/acfs/orcl/1/'
>  ACFS-9308: Loading installed ADVM/ACFS drivers.
>  ACFS-9321: Creating udev for ADVM/ACFS.
>  ACFS-9323: Creating module dependencies - this may take some time.
>  ACFS-9176: Entering 'ld usm drvs'

 >  ACFS-9428: Failed to load ADVM/ACFS drivers. A system reboot is recommended.
>  ACFS-9310: ADVM/ACFS installation failed.


The solution to this problem is to apply the one off patch (25078431) to fix this issue with ACFS/ADVM drivers in RHEL > 7.3. Yes, there is a metalink not available for the same file too.
But in our setup even the patch failed to fix the issue as the the .gridSetup -applyoneoffs comes out within 1-2 seconds we ran this command, I mean in short it did nothing and pretends that it applied the patch but the ‘opatch lspatches‘ not showing anything.

Well, we raised this issue with Oracle and they passed it to their development team as there were lot’s of other things running on this DB.
And as you know their DEV team, they don’t have any fixed SLA. Well there is a reason too for them doing like that, as development team does lot’s of testing and regressions hence that is something acceptable.

Well, this problem we anyhow to fix as we had an important test that we planned to perform on this system.
So, comes the time to apply the temporary fix, of course a crude/raw one 🙂

Now, as on this system we don’t need the ACFS, so we can disable the feature right at the code/binary level.
Below are the two main files that when renamed disabled this feature and you are all good to bypass this root.sh check.



acfsdriverstate
acfsroot



You simply have to rename them and re-run the root.sh script it will pass this time and you are done with your GI installation.

root.sh failing while installing 12cR2 on RHEL7 “Failed to create keys in the OLR” – Did your hostname starts with a number ?

Posted by FatDBA on July 29, 2019

Hi Guys,

I know its been too long since i last posted and it all happened due to some site authentication issues and some personal priorities. Here I am back with new issues, all related with performance, administration, troubleshooting, optimization and other subjects.

This time would like to share one of the issue that i have faced while installing Oracle 12c Release 2 (Yes, I still do installations, sometimes 🙂 ) on a brand new RHEL7 box where everything was good till I ran root.sh which got failed due to a weird error which initially got no hint behind the problem.
Initially i though if this qualifies to be a post and deserves a place here but actually I have spend few days identifying the cause and hours that I have spend with support, so just want to save all that time for you all who might facing the same issue and looking something on Google 🙂

So lets get started!
This is what exactly I got when ran the root.sh script



[root@8811913-monkey-db1:/u011/app1/12.2.0.1/grid]# ./root.sh
Performing root user operation.

The following environment variables are set as:

The error simply said that the script failed to ‘create the keys in OLR’. These keys were for HASD that it was attempting to add. I verified all run time logs that got created the time but they too gave no idea about this problem. That is when I had to engage the Oracle customer support and came to know that this all happened due to a new BUG (BUG 26581118 – ALLOW HOSTNAME WITH NUMERIC VALUE) that comes in to picture when you have the hostname starts with a numeral or number and is an RHEL7 and is specific to Oracle 12c Release 2.

Oracle suggested a bug fix (Patch Number: 26751067) for this issue. This is a MERGE patch and fixes both Bug 25499276 & 26581118. One more thing, you have to apply this patch before the root.sh script.
So let me quickly show how to do that (removing all redundant and other sections).



[oracle@8811913-monkey-db1:/u011/app1/12.2.0.1/grid/OPatch]$ ./opatch napply -oh /u011/app1/12.2.0.1/grid -local 26751067/26751067/

[oracle@8811913-monkey-db1:/u011/app1/12.2.0.1/grid/OPatch]$


Ran the root.sh after patching and it went smooth.
BTW, in case you don’t want to do all this, simply change the hostname and put any alphabet in front of your hostname i.e. 8811913 –> A8811913 — That’s It!

Hope It Helps!

Thanks

12c OEM Error: LongOpManager$ZombieDetection:1017

Posted by FatDBA on August 31, 2018

Hey Pals,

I am sure, few of the us who have the 12c EM configured on their systems must have received one of the annoying alert/incident where the EM Agent on the server has reported
something about the ‘Zombie’ processes repeatedly.

I recently encountered one such issue with this Production system where the 12c agent frequently sending zombie related alerts, like one below. So, this post of all about handling such issues
and how to fix them or to avoid them.

Host=dixitlab.asi.dixson.corp 
Target type=Agent 
Target name=dixitlab.asi.dixson.corp:3873 
Message=Problem: java.lang.Throwable:oracle.sysman.gcagent.tmmain.execution.LongOpManager$ZombieDetection:1017 
Severity=Critical 
Problem creation time=May 5, 2018 10:22:48 AM ADST 
Last updated time=Aug 29, 2018 1:00:47 AM ADST 
Problem ID=113 
Problem key=java.lang.Throwable:oracle.sysman.gcagent.tmmain.execution.LongOpManager$ZombieDetection:1017 
Incident count=5 
Problem Status=New 
Priority=None 
Escalated=No 
Problem acknowledged By Owner=No 
Rule Name=OEM12c-Problems,Enterprise Problems 
Rule Owner=SYSMAN 

Next quick thing in such cases is always checking the agent (gcagent) logs to understand the exact error or issues with EM or Agent.
And as expected the logs has something interesting in them, i saw a DEBUG message captured where Zombie Detection was initiated by the agent after a delay of lot of attempts.
This happens when an EM Agent task such as collecting metrics is running more than the expected time, the process is marked as a zombie and is one of the leading causes of agent crash or halt.

X-AGENT_PERSISTENCE_WAIT_TIME: 60
X-AGENT_PERSISTENCE_ID: https://dixitlab1.asi.dixson.corp:1830/emd/main/
2018-08-29 17:10:26,050 [31:858161EB] DEBUG - Submitting task ZombieDetector for execution
2018-08-29 17:10:26,050 [216:1AE716D8] DEBUG - Begin task ZombieDetector on Thread: GC.SysExecutor.8
2018-08-29 17:10:26,050 [216:69BEAC9D:GC.SysExecutor.8 (ZombieDetector)] DEBUG - Scheduling next ZombieDetector.Task after delay 60000 including periodShift of 0 milliseconds

There are few of the ways to avoid such issues.
1. Set _zombieSuspensions=TRUE
2. Set _canceledThreadWait=900
3. set _zombieThreadPercentThreshold=0

Other way, that is to avoid the alerts/incidents you can set one of the ‘Hidden’ parameter “_zombieCreateIncident=” to FALSE and set it in the agent configuration file followed by agent restart.
This

[oracle@dixitlab config]$
[oracle@dixitlab config]$ pwd
/u01/app/oracle/new_agent12c/agent_inst/sysman/config


[oracle@dixitlab config]$ more emd.properties|grep _zombieCreateIncident

Collecting Exadata Cell Performance Statistics using ‘Cellperfdiag.sql’

Posted by FatDBA on July 22, 2018

Hi Guys,

Last week we finished migration for one of the customer who recently purchased the Oracle Exadata Machines (X6-2), after that complex data movement is successfully completed we observed some great performance improvements without actually making any changes and exadata features in action.

But its not that the Exa machines are ‘In-frangible’ Or Unbreakable. There are many of the times when you actually have to understand the Cell/Computer Nodes or system wide performance and output from tools like Sundiag, Exawatcher, Exachk, TFA, SOS report etc. were not sufficient.

For the purpose of ‘Cell Performance DIAG info’ Oracle has provided a script to collect Exadata Cell Performance statistics which you can use to interpret the issues.

Output of the script is distributed into several sections
1. Cell specific parameters
2. Top CELL waits with wait times (Worst Times)
3. Cell Configuration details

Script to Collect Exadata Cell Performance Information (cellperfdiag.sql) (Doc ID 2038493.1)
Below is the output from one of the Cell Node of a lower environment.


CELLPERFDIAG DATA FOR DixitLab_July19_0257

IMPORTANT PARAMETERS RELATING TO CELL PERFORMANCE:

INST_ID NAME                                     VALUE

      1 cell_offload_plan_display                PDTO
      1 cell_offload_processing                  TRUE
      2 cell_offload_compaction                  ADAPTIVE
      2 cell_offload_decryption                  TRUE

DBMS_XPLAN and its different options/arguments available

Posted by FatDBA on May 10, 2018

Hi Mates,

I am back after a long time to write something that is very vital piece of information when you are about to start any troubleshooting task, yes that is the EXECUTION PLAN, well there are many ways to generate the CBO plans (i.e. AUTOTRACE, extended/debug traces, utlxpls.sql, V$SQL_PLAN, Few of the specialized SQL specific AWR reports like awrsqrpt.sql, STS etc.) but the most common and best way of doing thisng in this subecjt is to use DBMS_XPLAN & its function DISPLAY_CURSOR.

So, yes today’s topic is to understand what all options do we have to generate a more interactive, detailed, elaborative plans.

Okay will start it with very rudimentary (BASIC) styled plan and slowly will use rest of the arguments/options available. The plan includes the operation, options, and the object name (table, index, MV, etc)


SQL> SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR('0h79fq6vx4p99',0,'BASIC'));

PLAN_TABLE_OUTPUT
------------------------------------------------------------------------------------
EXPLAINED SQL STATEMENT:
------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

------------------------------------
| Id  | Operation         | Name   |
------------------------------------
|   0 | SELECT STATEMENT  |        |
|   1 |  TABLE ACCESS FULL| DIXEMP |
------------------------------------

Next is the most common way of generating the plans that’s with the DISPLAY function which allows us to display the execution plan stored in the plan table. First we explain a SQL statement.
Next we use the DBMS_XPLAN.DISPLAY function to display the execution plan.


SQL> explain plan for select * from dixemp;
Explained.

SQL> SELECT * FROM TABLE(dbms_xplan.display);


PLAN_TABLE_OUTPUT
------------------------------------------------------------------------------------
Plan hash value: 3980174453

----------------------------------------------------------------------------
| Id  | Operation         | Name   | Rows  | Bytes | Cost (%CPU)| Time     |
----------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |    14 |   532 |     3   (0)| 00:00:01 |
|   1 |  TABLE ACCESS FULL| DIXEMP |    14 |   532 |     3   (0)| 00:00:01 |
----------------------------------------------------------------------------

Next is the ‘ALLSTATS LAST’ option for FORMAT parameter. Lets see how to use it.
ALLSTATS is a shortcut for IOSTATS and MEMSTATS (e.q. BUFFER information) information and the other keyword LAST can be specified to see only the statistics for the last execution.


SQL> SELECT * FROM TABLE(DBMS_XPLAN.display_cursor(format=>'ALLSTATS LAST'));

PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL_ID  0h79fq6vx4p99, child number 0
-------------------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

--------------------------------------------------------------------------------------
| Id  | Operation         | Name   | Starts | E-Rows | A-Rows |   A-Time   | Buffers |
--------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |      1 |        |     14 |00:00:00.01 |      10 |
|   1 |  TABLE ACCESS FULL| DIXEMP |      1 |     14 |     14 |00:00:00.01 |      10 |
--------------------------------------------------------------------------------------

But if you take a look at the above plan you’ll see that the plan doesn’t contain few of the vital columns or stats like COST and bytes processed (BYTES) as it doesn’t comes by default with that, you actually have to add few more predicates to get that info. That is +cost and +bytes with your FORMAT parameter.

Below is how you can get that missing info from the plan.


SQL> SELECT * FROM TABLE(DBMS_XPLAN.display_cursor(sql_id=>'0h79fq6vx4p99',format=>'ALLSTATS LAST +cost +bytes'));

PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL_ID  0h79fq6vx4p99, child number 0
-------------------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

-----------------------------------------------------------------------------------------------------------
| Id  | Operation         | Name   | Starts | E-Rows |E-Bytes| Cost (%CPU)| A-Rows |   A-Time   | Buffers |
-----------------------------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |      1 |        |       |     3 (100)|     14 |00:00:00.01 |      10 |
|   1 |  TABLE ACCESS FULL| DIXEMP |      1 |     14 |   532 |     3   (0)|     14 |00:00:00.01 |      10 |
-----------------------------------------------------------------------------------------------------------

And the ALL parameter will give you the general plan but rest all of the details like Query Block Name / Object Alias, Predicate Information, column projection details.


SQL> SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR('0h79fq6vx4p99',0,'ALL'));

PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL_ID  0h79fq6vx4p99, child number 0
-------------------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

----------------------------------------------------------------------------
| Id  | Operation         | Name   | Rows  | Bytes | Cost (%CPU)| Time     |
----------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |       |       |     3 (100)|          |
|   1 |  TABLE ACCESS FULL| DIXEMP |    14 |   532 |     3   (0)| 00:00:01 |
----------------------------------------------------------------------------

Query Block Name / Object Alias (identified by operation id):
-------------------------------------------------------------

   1 - SEL$1 / DIXEMP@SEL$1

Column Projection Information (identified by operation id):
-----------------------------------------------------------

   1 - "DIXEMP"."EMPNO"[NUMBER,22], "DIXEMP"."ENAME"[VARCHAR2,10],
       "DIXEMP"."JOB"[VARCHAR2,9], "DIXEMP"."MGR"[NUMBER,22],
       "DIXEMP"."HIREDATE"[DATE,7], "DIXEMP"."SAL"[NUMBER,22],
       "DIXEMP"."COMM"[NUMBER,22], "DIXEMP"."DEPTNO"[NUMBER,22]

ALLSTATS is a shortcut for IOSTATS and MEMSTATS (e.q. BUFFER information) with your plan.


SQL> SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY_CURSOR('0h79fq6vx4p99',0,'ALLSTATS'));

PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL_ID  0h79fq6vx4p99, child number 0
-------------------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

--------------------------------------------------------------------------------------
| Id  | Operation         | Name   | Starts | E-Rows | A-Rows |   A-Time   | Buffers |
--------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |      7 |        |     98 |00:00:00.01 |      70 |
|   1 |  TABLE ACCESS FULL| DIXEMP |      7 |     14 |     98 |00:00:00.01 |      70 |
--------------------------------------------------------------------------------------

Now, if you want to view additional details of your plan, for example set of hints to reproduce the statement or OUTLINE, you can use it in your format parameter.


SQL> SELECT * FROM TABLE(DBMS_XPLAN.display_cursor(sql_id=>'0h79fq6vx4p99',format=>'ALLSTATS LAST +outline'));

PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL_ID  0h79fq6vx4p99, child number 0
-------------------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

--------------------------------------------------------------------------------------
| Id  | Operation         | Name   | Starts | E-Rows | A-Rows |   A-Time   | Buffers |
--------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |      1 |        |     14 |00:00:00.01 |      10 |
|   1 |  TABLE ACCESS FULL| DIXEMP |      1 |     14 |     14 |00:00:00.01 |      10 |
--------------------------------------------------------------------------------------

Outline Data
-------------

  /*+
      BEGIN_OUTLINE_DATA
      IGNORE_OPTIM_EMBEDDED_HINTS
      OPTIMIZER_FEATURES_ENABLE('12.2.0.1')
      DB_VERSION('12.2.0.1')
      ALL_ROWS
      OUTLINE_LEAF(@"SEL$1")
      FULL(@"SEL$1" "DIXEMP"@"SEL$1")
      END_OUTLINE_DATA
  */

Adding or removing any data/stats from the plan, that’s possible using + or – signs follwed by argument.
Example: if you want t view cost and bytes information use +cost, +bytes in your plan or if you want to remove the same info in your run of dbms_xplan use -cost, -bytes.


SQL> SELECT * FROM TABLE(DBMS_XPLAN.display_cursor(sql_id=>'0h79fq6vx4p99',format=>'ALLSTATS LAST +cost +bytes'));

PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
SQL_ID  0h79fq6vx4p99, child number 0
-------------------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

-----------------------------------------------------------------------------------------------------------
| Id  | Operation         | Name   | Starts | E-Rows |E-Bytes| Cost (%CPU)| A-Rows |   A-Time   | Buffers |
-----------------------------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |      1 |        |       |     3 (100)|     14 |00:00:00.01 |      10 |
|   1 |  TABLE ACCESS FULL| DIXEMP |      1 |     14 |   532 |     3   (0)|     14 |00:00:00.01 |      10 |
-----------------------------------------------------------------------------------------------------------

You can write a mix of both as below


SQL> SELECT * FROM TABLE(dbms_xplan.display_cursor(sql_id => '0h79fq6vx4p99', cursor_child_no => 0, FORMAT => 'TYPICAL -ROWS -BYTES +COST +PARALLEL +PARTITION +IOSTATS +MEMSTATS +ALIAS +PEEKED_BINDS +OUTLINE +PREDICATE -PROJECTION +REMOTE +NOTE'));

PLAN_TABLE_OUTPUT
-----------------------------------------------------------------------------------------------------------------------
SQL_ID  0h79fq6vx4p99, child number 0
-------------------------------------
select /*+ GATHER_PLAN_STATISTICS */ * from dixemp

Plan hash value: 3980174453

--------------------------------------------------------------------------------------------------------------
| Id  | Operation         | Name   | Starts | E-Rows | Cost (%CPU)| E-Time   | A-Rows |   A-Time   | Buffers |
--------------------------------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |        |      7 |        |     3 (100)|          |     98 |00:00:00.01 |      70 |
|   1 |  TABLE ACCESS FULL| DIXEMP |      7 |     14 |     3   (0)| 00:00:01 |     98 |00:00:00.01 |      70 |
--------------------------------------------------------------------------------------------------------------

Query Block Name / Object Alias (identified by operation id):
-------------------------------------------------------------

   1 - SEL$1 / DIXEMP@SEL$1

No active extraction maps – Golden Gate STATS command, what’s that ?

Posted by FatDBA on April 8, 2018

Hey Mates,

Not sure if you guys have ever encountered a situation where you’ve got a return message “No active extraction maps” from Golden Gate STATS command against your Golden Gate process.
For GG newcomers, STATS command is used to display statistics for one or more Extract,Pump/Replicat groups and the output includes DML and DDL operations that are included in the Oracle GoldenGate configuration.

Now coming back to the error scenario. Let’s see where we got that message and what does that means.

GGSCI (rac1.localdomain as ggadmin1@dixitdb1) 20> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt
MANAGER     RUNNING
EXTRACT     RUNNING     GGTUNEX1    00:00:03      00:00:08
EXTRACT     RUNNING     GGTUNPU1    00:00:00      00:00:01
REPLICAT    RUNNING     GGTUNRP1    00:00:00      00:00:03

Now when i tried to check statistics for my processes, we’ve got a message which says that there are “No active extraction maps”

GGSCI (rac1.localdomain as ggadmin1@dixitdb1) 18> stats GGTUNPU1

Sending STATS request to EXTRACT GGTUNPU1 ...
No active extraction maps.

GGSCI (rac1.localdomain as ggadmin1@dixitdb1) 22> stats GGTUNPU1

Sending STATS request to EXTRACT GGTUNPU1 ...
No active extraction maps.

So what does that means ??
The message that is displayed indicates that nothing has been processed in the extract or replicat. Once data for the tables in the extract and replicat are processed (captured from or applied to DB) the STATS command produces processing statistics.

Let me try to do some manipulations at the source table which is part of replication and see if this brings something to STATS results.

SQL> update emp set ENAME='KARTIKEY' where EMPNO=8090;
1 row updated.

SQL> commit;
Commit complete.

Let’s try now.

GGSCI (rac1.localdomain as ggadmin1@dixitdb1) 43> stats GGTUNEX1

Sending STATS request to EXTRACT GGTUNEX1 ...

Start of Statistics at 2018-04-05 04:03:08.
