Hello

I want to restart a 10g database on ASM

Could you please let me know the startp and shutdown sequence?
I would like to shutdown everything including database, ASM and cluster and startup again

I read at various places but not sure of the sequence

For database DB with database instance DB01 and DB02 having ASM instances ASM01 and ASM02 on node1 and node2, I understand following would be the sequence

1)
Login as root on node1
cd $CRS_HOME/bin
./crsctl start crs        

2)
Login as root on node2
cd $CRS_HOME/bin
./crsctl start crs        

3)
login as oracle on node1
$ORACLE_HOME/bin/srvctl start nodeapps -n node1

4)
login as oracle on node2
$ORACLE_HOME/bin/srvctl start nodeapps -n node2

5)
login as oracle on node1
start ASM instance on node1
$ORACLE_HOME/bin/srvctl start asm01 -n node1

6)
login as oracle on node2
start ASM instance on node2
$ORACLE_HOME/bin/srvctl start asm02 -n node2

7)
Start oracle database (from any node)
$ORACLE_HOME/bin/srvctl start database -d DB

 
A. Could you please confirm if the above sequence is correct?
B. This sequence if corrrect, is same for 10g and 11g?
C. Is shutdown sequence exact reverse of the above?


Thank you

Regards

Crs should start at system boot. Crs would then bring things up in the correct order for you. Why are you needing to do this manually?

Hi,

Shutdown and startup sequence in RAC.

1.shutdown database using srvctl command.

2.shutdown asm instance using srvctl.

3.stop crsctl

For startup

Just cluster startup will bring all databases and asm instance.

With Regards,

Even these tasks are commonly done alongwith the above mentioned steps -

Before shutdown :

Another point is to Backup/remove the Oracle cron and temporarily stop the Oracle Enterprise Management (OEM) alerts before the shutdown to avoid the obvious alerts else it would flood with a lot of alerts.

After startup :

1. Restore the above processes to enable monitoring on OEM and put the oracle cron back after startup.
2. To validate that the clustered resources are running, execute crsstat.sh

Can you tell me how to Backup/remove the Oracle cron and how to put the oracle cron back after startup and also would like to know why we need to do this as part of shutdown and startup?

Database used -- Oracle RAC 11gr2.

OS used --- RHL 6.4

Thank you

It's mostly/only applicable in scheduled maintenance as a pre-work.

Pre-work before shutdown :

1. Backup, Remove Cron,

    1. Go to Oracle directory : cd /opt/oracle
    2. crontab -l > crontab.backup
    3. crontab -r2. Set Blackout of OEM

2. Set Blackout of OEM

    1. emctl start blackout outage -nodeLevel

Post-work on all instances after startup :

1. Restore the crontab.


    1. Go to Oracle directory : cd /opt/oracle
    2. crontab crontab.backup
    3. crontab -l --> to validate

2. Stop the OEM Blackout

    1. emctl stop blackout outage


Regards,
Lalit

Yes it's a silly typo, I was using add numbered list tool to format and I overlooked at the typo. It should be :

crontab -r

Depends on what is scheduled in Oracle crontab. I mentioned that it is usually done in scheduled maintenance. A lot of automated scripts are scheduled in crontab. Now I want to have a clean shutdown and startup. Since, I need to remove crontab before shutdown, obviously I have to take a backup before I remove it. And restore it after startup.
