Today’s Issue:


Problem with Oracle 12c Installation on RHEL6.

Error Logs: installActions2013-06-29_12-50-04AM.log – Notepad

Hi Everyone,


Hope everyone of us are quite excited after the release of Oracle 12c r1 database and all of us are ready to test new features packed inside the ‘New Red’

But it seems like i have to wait to perform some tests and learn more about the 12c.


Today I’ve downloaded software from oracle official website:

Oracle Database 12c Release 1 ( for Linux x86-64

Download linuxamd64_12c_database_1of2.zip (1,361,028,723 bytes) (cksum – 3389130601)
Download linuxamd64_12c_database_2of2.zip (1,116,527,103 bytes) (cksum – 273248753)


and i have already created a brand new Red Hat 6 machine (64 Bit) to install the package and wet my hands with it,


Here is the situation/problem:

I’ve completed all pre–requisites and checks e.g. installed all needed rpm’s

Modified profiles and kernel parameters

Made changes to ‘limits.conf’ file

Created required usergroups and user accounts

Set SELINUX to permissive

Set the DISPLAY and launched the .runInstaller


Everything went perfect –

~ Prepare  — Completed

~ Copy Files — Completed

While ‘Linking Libraries’ step received an error message which says about which i skipped and soon after that got many different errors related to linking, which i again skipped.

Same has happened during ‘Net Configuration Step’ and ‘DB Configuration Assistant’, which i again skipped (Otherwise the message keeps on coming on screen)


After that I’ve executed root.sh and related scripts from root account.


But now after this installation has completed (With many errors related to linking and Configuration files), I’m not able to launch the sqlplus executable. Even after setting the ORACLE_BASE, ORACLE_HOME.



Database: Oracle 12c Release 1

Package Name: Oracle Database 12c Release 1 ( for Linux x86-64

Files: linuxamd64_12c_database_1of2.zip  and linuxamd64_12c_database_2of2.zip

[oracle@oracle12c ~]$ uname -m

Hi Everyone,

I’ve recently created an ASM instance on one of my Test DB Machine which has 10g R2 installed on Red Hat Linux 5 platform . It was absolutely good until a recent system issue which forced us to reboot machine and soon after the machine is up and we tried starting ASM instance it’s prompting following errors on the terminal which reads:

[oracle@localhost ~]$ export ORACLE_SID=+ASM
[oracle@localhost ~]$ sqlplus / as sysdba

SQL*Plus: Release – Production on Fri Oct 12 18:59:37 2012
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to an idle instance.

SQL> startup
ORA-15032: not all alterations performed
ORA-15063: ASM discovered an insufficient number of disks for diskgroup “‘+TESTDB_DATA1′”

OR Sometimes

ORA-29701: unable to connect to Cluster Manager
Then i tried to check the status of raw disks I’ve made during the Failgroup creation and found the permissions has somehow reverted back to root:root which should be oracle:oinstall in place for all raw disks.

[root@localhost ~]# cd /dev/raw
[root@localhost raw]# ls -ltr
total 0
crw——- 1 root root 162, 1 Oct 12 18:58 raw1
crw——- 1 root root 162, 2 Oct 12 18:58 raw2
crw——- 1 root root 162, 3 Oct 12 18:58 raw3
crw——- 1 root root 162, 4 Oct 12 18:58 raw4

(There are four raw disks and raw 1 and raw 2 part of Failgroup 1 and raw 3 and raw 4 is Failgroup 2)

so, i manually changed the permissions again to oracle:oinstall and modified the mode to 660 and then tried to start the ASM instance and as per my expectations it started working good.
But to test i rebooted machine again after this permissions and mode change and it’s started doing the same and permissions and ownership rolled back to root:root

Below are the contents of boot up script– /etc/rc.d/rc.local

[root@localhost raw]# vi /etc/rc.d/rc.local

# This script will be executed after all the other init scripts.
# You can put your own initialization stuff in here if you don’t
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

/sbin/losetup /dev/loop1 /asmdisk/disk1
/sbin/losetup /dev/loop2 /asmdisk/disk2
/sbin/losetup /dev/loop3 /asmdisk/disk3
/sbin/losetup /dev/loop4 /asmdisk/disk4
raw /dev/raw/raw1 /dev/loop1
raw /dev/raw/raw2 /dev/loop2
raw /dev/raw/raw3 /dev/loop3
raw /dev/raw/raw4 /dev/loop4

Any Suggestions ???
