Crsctl start/stop CRS and Crsctl start/stop cluster differences in RAC

Website Explanation:

Crsctl start/stop CRS-Manage Start/stop theentire Oracle clusterware stack on a node, including the OHASD process, this command was to be usedOnly on the local node..

crsctl start/stop Cluster-Manage start/stop the Oracle clusterware stack on local node if your do not specify Either-all or-n and nodes remote if Option-n Or-all be specified,Not including the OHASD process.You can ' t start/stop clusterware stack without OHASD process running.

Despite Crsctl start/stop CRS manage entire Oracle clusterware stack on local node Crsctl start/stop CRS no allow Manage remote nodes, unlike Crsctl start/stop cluster that allows I manage all the nodes, but if the process Oash is Runing.

to manage Oracle Clusterware Stack on remote nodes, the OHASD (Oracle High Availability Services Daemon) must be Runni Ng on all managed nodes. (i.e using CRSCTL start cluster-n <node1>, <node2>)

Then if you try with Crsctl start Cluster-n node1,node2 and your local node is node1 and on Node1 or node2 ohasd not Runni Ng this command would fails.

Chinese explanation:

1 Crsctl start/stop CRS is a single-section management

Crsctl start/stop cluster [-all all nodes] can manage multiple nodes

2 CRSCTL start/stop CRS Management CRS contains process OHASD

Crsctl start/stop cluster does not contain OHASD processes must be started before the OHASD process can be used

3 11GR2 RAC Manual start or shutdown process

The process of manually starting and shutting down using CRSCTL start/stop cluster is as follows:

Crsctl Start/stop Cluster-all will start all nodes where Ohas is the boot state

Manual start/close process with Crsctl start/stop CRS

Node 1

Crsctl Start/stop CRS will actually launch the Oracle CRS Managed Resources later

Node 2

Crsctl Start/stop CRS

......

Enable CRS to start on reboot

Crsctl Enable CRS

Disable CRS to start on reboot

CRSCTL Disable CRS

4 Querying for resource startup conditions

CRSCTL Stat res-init-t

Note:

Crsctl Start/stop CRS has the same effect as Crsctl Start/stop
