Source Oracle Environment Easily

Filed under: oracle,shell scripting — mdinh @ 3:50 am

I have been patching a lot lately and wanted a fast and easy method to source Oracle environment.

The objective is to copy, paste from action plan vs having to selectively copy, edit, paste.

Example: . /media/patch/gi.env vs . oraenv — +ASM[n]

Started by creating gi.env which will be used to source GI for all RAC hosts.

You are probably thinking, isn’t it a PITA to have to edit and maintain all the gi.env per host, e.g. 6 nodes RAC cluster?

Rightfully so and it’s a PITA unless it’s dynamic.

There is one requirement: host# = instance#

Hence, +ASM1 is running on host05 will not work.

Next step would probably be to script the tasks.

DEMO1:

[oracle@racnode-dc1-1 ~]$ ps -ef|grep [p]mon
oracle 10818 1 0 03:58 ? 00:00:00 asm_pmon_+ASM1
oracle 11456 1 0 03:58 ? 00:00:00 ora_pmon_hawk1
oracle 11763 1 0 03:58 ? 00:00:00 mdb_pmon_-MGMTDB

[oracle@racnode-dc1-1 ~]$ . /media/patch/gi.env
ORACLE_SID = [+ASM1] ? The Oracle base remains unchanged with value /u01/app/oracle
ORACLE_SID=+ASM1
ORACLE_BASE=/u01/app/oracle
GRID_HOME=/u01/app/12.2.0.1/grid
ORACLE_HOME=/u01/app/12.2.0.1/grid
Oracle Instance alive for sid “+ASM1”

[oracle@racnode-dc1-1 ~]$ . /media/patch/hawk.env
ORACLE_SID = [+ASM1] ? The Oracle base remains unchanged with value /u01/app/oracle
ORACLE_UNQNAME=hawk
ORACLE_SID=hawk1
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/11.2.0.4/db1
Oracle Instance alive for sid “hawk1”

[oracle@racnode-dc1-1 ~]$ srvctl status database -d $ORACLE_UNQNAME
Instance hawk1 is running on node racnode-dc1-1
Instance hawk2 is running on node racnode-dc1-2

[oracle@racnode-dc1-1 ~]$ df -h /media/patch/

[oracle@racnode-dc1-2 ~]$ srvctl status database -d $ORACLE_UNQNAME
Instance hawk1 is running on node racnode-dc1-1
Instance hawk2 is running on node racnode-dc1-2

[oracle@racnode-dc1-2 ~]$ cat /media/patch/gi.env
set +x
unset ORACLE_UNQNAME
h=$(hostname -s)
n=1
. oraenv <<< +ASM${h:${#h} – $n}
export GRID_HOME=$ORACLE_HOME
env|egrep ‘ORACLE|GRID’
sysresv|tail -1

[oracle@racnode-dc1-2 ~]$

[oracle@racnode-dc1-2 ~]$ cat /media/patch/hawk.env
set +x

export ORACLE_UNQNAME=hawk
