Using DBCA (DB Create) in Silent Mode.

Posted by FatDBA on August 23, 2013

DBCA is one of the most important and easiest utility to create new databases. Most of us have used it during our careers in GUI mode, but we have an option to launch it in non-graphical mode (Non-Interactive Mode) as well. Below provided steps can be performed to create database in silent/non-interactive mode. So you can launch DBCA in text mode from your favorite ssh client/terminal like putty, secureCRT, SSH Tectia Client etc. and can save yourself from that ‘old’ manual DB create methods (Using catprocs, catalog sql’s and creating new dump directories).

To create database: This requires a response file which includes all necessary details like GGDBNAME (Global Database Name), SID, Listener Name, SYS/SYSTEM/DBSNMP/SYSMAN Passwords etc.
Browser the response file (ORACLE_HOME/assistants/dbca) and make all mandatory changes.

Step 1: Location of response file
[oracle@prashant dbca]$ pwd
/u01/app/oracle/product/11.2.0/db_1/assistants/dbca    — Default Location of Response File.

[oracle@prashant dbca]$ ls
dbca.rsp  doc  jlib  logs  templates

Create a copy of original file.
[oracle@prashant dbca]$ cp dbca.rsp  dbcacreatedb.rsp

[oracle@prashant dbca]$ ls
dbcacreatedb.rsp  dbca.rsp  doc  jlib  logs  templates

Step 2:
Edit all mandatory changes in response file.
GDBNAME = “silent”
SID = “silent”
SYSPASSWORD = “oracle90”

Although there are various sections inside the response file “.rsp” file like createdatabase, deleteDatabase, createTemplateFromDB or createCloneTemplate. In this post we have talk only about ‘createDatabase‘ and is the area of interest (Used to create new database).

All Examples :
1. dbca -progress_only -responseFile <response file>
Display a progress bar depicting progress of database creation

2. dbca -silent -responseFile <response file>
Creates database silently. No user interface is displayed.

3. dbca -silent -createDatabase -cloneTemplate
-responseFile <response file>    
Creates database silently with clone template. The template in
responsefile is a clone template.

4. dbca -silent -deleteDatabase -responseFile <response file>
Deletes database silently.

Step: 3

So, we are going to install the database using ‘STEP 3’ without using -cloneTemplate. This will create database silently and will show progress in percentages.
[oracle@prashant dbca]$ dbca -silent -createDatabase -responseFile dbcacreatedb.rsp
Copying database files
1% complete
3% complete
11% complete
18% complete
26% complete
37% complete
Creating and starting Oracle instance
40% complete
45% complete
50% complete
55% complete
56% complete
60% complete
62% complete
Completing Database Creation
66% complete
70% complete
73% complete
85% complete
96% complete
100% complete
Look at the log file “/u01/app/oracle/cfgtoollogs/dbca/silent/silent.log” for further details.

It seems that Database Creation is successful completed. Let’s check creation  log file.
File: “/u01/app/oracle/cfgtoollogs/dbca/silent/silent.log”

Okay, while checking log file i found some new entries after creating database:

Database creation complete. For details check the log-files at:
Database Information:
Global Database Name:silent
System Identifier(SID):silent

[oracle@prashant dbca]$ cd /u01/app/oracle/cfgtoollogs/dbca/silent
[oracle@prashant silent]$ ls -ltr
total 104
-rw-r—– 1 oracle oinstall  1372 Aug 23 11:47 rmanRestoreDatafiles.sql
-rw-r—– 1 oracle oinstall   330 Aug 23 11:49 CloneRmanRestore.log
-rw-r—– 1 oracle oinstall  1135 Aug 23 11:50 cloneDBCreation.log
-rw-r—– 1 oracle oinstall     8 Aug 23 11:50 postScripts.log
-rw-r—– 1 oracle oinstall     6 Aug 23 11:50 lockAccount.log
-rw-r—– 1 oracle oinstall   349 Aug 23 11:51 postDBCreation.log
-rw-r—– 1 oracle oinstall   458 Aug 23 11:51 OraDb11g_home1_silent_creation_checkpoint.xml
-rw-r—– 1 oracle oinstall 66392 Aug 23 11:51 trace.log
-rw-r—– 1 oracle oinstall   654 Aug 23 11:51 silent.log

* There are some interesting files generated during DB creation like CloneRmanRestore.log, cloneDBCreation.log, postDBCreation.log and rmanRestoreDatafiles.sql.

Let’s check our new database ‘Silent’.
[oracle@prashant silent]$ ps -ef|grep pmon
oracle   12671     1  0 Aug20 ?        00:00:03 ora_pmon_sairam
oracle   20771     1  0 11:50 ?        00:00:00 ora_pmon_silent
oracle   22315 18308  0 13:06 pts/2    00:00:00 grep pmon

Okay we have a PMON for databse (Silent).
[oracle@prashant silent]$ . oraenv
ORACLE_SID = [sairam] ? silent
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 is /u01/app/oracle
[oracle@prashant silent]$ sqlplus / as sysdba

# creates recovery catalog script to back up database and archived logs
RMAN> CREATE SCRIPT backup_whole
COMMENT “backup whole database and logs”

RMAN> list script names;

The PRINT SCRIPT command is used to view the contents of a stored script.
The REPLACE SCRIPT command is used to update the contents of a stored script.
The EXECUTE SCRIPT command is used to execute the commands in the stored script.
