Disable/Enable Automatic Startup Oracle HAS
On 11gR2, Oracle Clusterware consists of two separate stacks: an upper stack anchored by the Cluster Ready Services (CRS) daemon (crsd) and a lower stack anchored by the Oracle High Availability Services daemon (ohasd).
So.. How to disable/enable Oracle HAS.
Use the crsctl disable has command to disable automatic startup of the Oracle High Availability Services stack when the server boots up.
How about "crsctl disable/enable crs" on 11gR2?
They disable/enable automatic startup of Oracle HAS.
I posted "check enable/disable the startup of CRS".. that show Oracle Clusterware version <= 11gR1, we can check from "crsstart" file. On 11gR2, crsstart file is not used ???
Use the crsctl disable crs command to prevent the automatic startup of Oracle High Availability Services when the server boots.
Use the crsctl enable crs command to enable automatic startup of Oracle High Availability Services when the server boots.
So.. How to disable/enable Oracle HAS.
Use the crsctl disable has command to disable automatic startup of the Oracle High Availability Services stack when the server boots up.
# crsctl config hasHow to know Oracle HAS is enabled(if doesn't use "crsctl config has")

# cat /etc/oracle/scls_scr/rhel5-test/root/ohasdstrUse the crsctl enable has command to enable automatic startup of the Oracle High Availability Services stack when the server boots up.

# crsctl enable hasIf We just check HAS Disable/Enable status, that uses "crsctl config has" command, it's easier than "ohasdstr" file checking.

Is there a typo or am I missing something. I am expecting
cat /etc/oracle/scls_scr/rhel5-test/root/crsstart
disable
for the last execution because you disable it but your post says it is
cat /etc/oracle/scls_scr/rhel5-test/root/crsstart
enable
Am I missing something ?
I'll check again...
But In my Test System, It's "enable" status in /etc/oracle/scls_scr/rhel5-test/root/crsstart file.
After test installation Grid Infrastructure for a Standalone Server (solaris)
$ crsctl check has
CRS-4638: Oracle High Availability Services is online
$ crsctl config has
CRS-4622: Oracle High Availability Services autostart is enabled.
$ cat /var/opt/oracle/scls_scr/sundb/root/crsstart
enable
$ cat /var/opt/oracle/scls_scr/sundb/oracle/ohasdstr
enable
$ crsctl disable has
CRS-4621: Oracle High Availability Services autostart is disabled.
$ cat /var/opt/oracle/scls_scr/sundb/root/crsstart
enable
$ cat /var/opt/oracle/scls_scr/sundb/oracle/ohasdstr
disable
$ crsctl enable has
CRS-4622: Oracle High Availability Services autostart is enabled.
$ cat /var/opt/oracle/scls_scr/sundb/root/crsstart
enable
$ cat /var/opt/oracle/scls_scr/sundb/oracle/ohasdstr
enable
That show... crsstart file not use anymore...
and if uses Grid Infrastructure for a Standalone Server "crsctl ... crs" can not use ...
$ crsctl disable crs
CRS-4013: This command is not supported in a single-node configuration.
