Oracle Clusterware daemons Enable/Disable Status

crsctl Using this command we can enable or disable oracle clusterware damemons. Run the following command to enable startup of all oracle clusterware daemons

crsctl enable crs

Run the following command to disable startup for all oracle clusterware daemons

crsctl diable crs

Usually we're enabling/disableing oracle clusterware daemons status using crsctl but no one checking wheather cluster already disabled/enabled or not ?

I just found YES we can check oracle clusterware daemons startup status in scls_scr directory from /etc/oracle

Example:

Enable:


[root@linux1 ~]# cd /u01/app/oracle/product/10.2.0/crs/bin


[root@linux1 bin]# ./crsctl enable crs
[root@linux1 bin]# cat /etc/oracle/scls_scr/linux1/root/crsstart
enable

After executing crsctl enable crs command clusterware daemons status updated in crsstart file "enable"

Disable:


[root@linux1 bin]# ./crsctl disable crs


[root@linux1 bin]# cat /etc/oracle/scls_scr/linux1/root/crsstart


disable

After executing crsctl disable crs command clusterware daemons status updated in crsstart file "disable". Have a great day to found oracle clusterware daemons status :-) ..

Terminating clsd session

Memorial Day and right now I am so busy at work that I haven’t had time to study. I do have a post half way complete on RAC Installation but I can finish that this weekend. So what can I blog about in the meantime?


Well today I have completed Oracle RAC Installation on Windows 2003 SP2. Next month I have a Solaris environment to setup that is RAC. I did 3 Linux ones last month (All Red Hat). What I will do is post through the install and what hiccups I ran into as well as what the gotcha were with each system.


So here we are 1:20  pm at night and I will be trying to get this done throughout the night. I am actually working on 3 posts in parallel. This, VIP Mondification on RAC Nodes, and then a post on some more RMAN Backup jobs. All good stuff. When I finish that I will try and get some more OCM 10g DBA posts up.
