CRS Resource in Oracle 10g includes GSD (Global serveice Daemon), ONS (Oracle Notification Service), VIP, Database, Instance and service
When you start the CRS in the 11GR2, you will be prompted that OHASD has been started. So what resources does this ohasd contain?

If you want to close the RAC can no longer pass the Crs_stop-all, this command is used by 10g, in 11g due to CRS information is also placed in the ASM instance, so to close ASM, must be closed CRS, the oracle11g RAC architecture is as follows
To shut down a RAC, you need to configure root in 2 nodes. Bash_profile
Export Oracle_home=/u01/grid/product/11gr2export path= $ORACLE _home/bin: $PATH
Turn off RAC
[[email protected] ~]# crsctl stop has[[email protected] ~]# crsctl stop has
Start RAC
[[email protected] ~]# crsctl start has[[email protected] ~]# crsctl start has
Crsctl other options, the following command only needs to be started on one node to turn off RAC Racnode1 is the host name of the node
[[email protected] ~]# crsctl stop cluster-n racnode1 racnode2
Start RAC
[Email protected] ~]# crsctl start cluster-n racnode1 racnode2
When the cluster is stopped directly, the associated resource will also be stopped. In practice, however, we operate more on the startup or shutdown of certain resources. Specifically, the SRVCTL command is used. This command is often forgotten, so you can use the Help option –h to view command help:
[email protected] ~]$ srvclt–h
This command shows the result is too long, not good to see, you can further view the help:
[email protected] ~]$ Srvctl start-hClose the database directly with the following command to see other related actions by using the help command above
[Email protected] ~]# srvctl stop database-d PROD
the CRS_CTL-T command is still available, and the 11g RAC has a bug instance that starts normally, but the status is offline
