SAPCTL Functionality and Usage for Oracle RAC environments

Hello,

Now we are going to show the functionality and the usage of sapctl service in RAC environments. Normally between srvctl, crsctl, sapctl you can get confuse with the commands you need to administrate the SAP HA subsystems (ASCS, ERS, DV, etc)

What does SAPCTL does?

1. You can create and remove any Oracle Clusterware configuration of the SAP HA subsystem.

2. You can start and stop the SAP HA subsystem that are created in the Oracle Clusterware, you can choose to start/stop as a whole or individual components.

3. You can check the status of any SAP HA subsystem created in the Oracle Clusterware.

4. You can relocate any SAP HA subsystem created in the Oracle Clusterware.

SAPCTL usage and commands

This working example assumes that you have completed all of this steps:

1. Oracle Clusterware is installed.

2. Oracle RAC is installed.

3. You have installed SAP and the SAPCTL package.

4. You have 2 RAC nodes.

5. Only ASCS and ERS services are installed in Oracle Clusterware, the SAP Instance is installed in a different host (No cluster service).

Previous Info:

First RAC Node:           erpdb01

Second RAC Node:      erpdb02

SAP SID:                      PRD

Oracle Version:            11.2.0.4

ASCS Instance:           ASCS01

ERS Instance:             ERS20

SAPCTL Version:          v8

First log in with sidadm to operating system level.

To check the status of all SAP HA subsystems installed in Oracle Clusterware you use this command:

     sapctl status all -sapsid PRD

To check the status of individual SAP HA subsystems installed in Oracle Clusterware you use this command:

     sapctl status abapvip/abapenq/abaprep -sapsid PRD

To check the which SAP Instace have been configured by Oracle Clusterware:

     sapctl config

To stop all SAP HA subsystems use this command:

     sapctl stop all -sapsid PRD

To stop all SAP HA subsystems use this command:

     sapctl start all -sapsid PRD

     As you can see the ERS Service will automatically started in the oposite node (erpdb02) where the ASCS service started.

If you need to start/stop individually any subsystem service you can use this commands:

     sapctl start/stop abapenq -sapsid PRD  

     sapctl start/stop abaprep -sapsid PRD

     sapctl start/stop abapvip -sapsid PRD (VIP IP for ASCS service)

Now the commands to manually relocate subsytem services between the RAC Nodes

     ASCS01 service is running on erpdb01 -> relocate to erpdb02

     ERS20 service is running on erpdb02

     sapctl relocate -sapsid PRD -abapenq/-abaprep ASCS01/ERS20 -to erpdb02/erpdb01

After the relocation of ASCS service is done, the ERS service automatically relocates to oposite node.

Hope it helps you!, don’t forget to like and rate if it was helpful.
