Configuring CA CSM › Run CA CSM on Another LPAR

Run CA CSM on Another LPAR

You can run CA CSM on another LPAR within a sysplex with a shared DASD. For example, you install CA CSM on LPAR1 and later you want to run it on LPAR2 without reinstalling.

Note: You can run CA CSM only on one LPAR at a time that is using the same USS file systems. You must have installed the correct level of CA Common Services for z/OS function CETNxxx on the new LPAR. The level of CA Common Services for z/OS function CETNxxx depends on your version of CA CSM and is the same version as on the first LPAR.

Important! CA CSM stores the USS paths that are used for the file systems in the CA Datacom database. The USS path names must be identically used on both LPAR systems.

For example, you have the following USS path on LPAR1:

/u/users/csmpt/PT51/mpm/scroot/DatabaseM/CA/CA_ACF2_-_MVS/

Use the same USS file system for the installation on LPAR2. When you restart CA CSM on LPAR2, Shared File System automatically creates the prefix before the USS path and mounts CA CSM to the correct system.

Follow these steps:

1. Log in to CA CSM running on LPAR1 and navigate to the Settings tab, System Settings, Mount Point Management. Select Unmount at Shutdown. Click Apply to save your changes.
2. Shut down CA CSM on LPAR1.
3. Unmount the CA CSM USS file system from LPAR1. This file system was mounted before executing the CA CSM application server started task or batch JCL. This file system is also referenced in the SAMPLIB(MSMLIB) member. For example:

   C_HOME=/parent_path/msmserv/version_number/msmruntime/tomcat
   

   The mountpoint in the previous case is for the following file system:

   /parent_path/msmserv/version_number/
   

4. (Optional) Verify the file system and the z/OS data set information that is required for the mountpoint by issuing the following command in OMVS:

   df -vkP | grep /parent_path/msmserv/version_number/
   

5. Mount the CA CSM USS file system on LPAR2.
6. Edit two XML files, context.xml and server.xml, that are at parent_path/msmserv/version_number/msmruntime/tomcat/conf using the Edit ASCII option. We recommend that you use the ISPF editor.
   • In the context.xml file, specify the following parameters:
     • SystemID
     • HostName
   • (Optional) If you need to change the port numbers that CA CSM uses in the URL for the new LPAR2 that CA CSM will now reside on, edit the server.xml file.
     • To edit the shutdown port, change the shutdown parameter in the following line:

       <Server port="25955" shutdown="MSMTCEND">
       

     • To edit the connection port and redirect port, change the port and redirectPort parameters in the following line:

       <Connector connectionTimeout="20000" port="25958" protocol="HTTP/1.1" redirectPort="25957"/>
       

   Note: You can predefine these files for each LPAR on which you want CA CSM to run. For example, you have two CA CSM eligible LPARs, LPAR1 and LPAR2. Create the context and server files are as follows:

   • For LPAR1: context.xml.LPAR1 and server.xml.LPAR1
   • For LPAR2: context.xml.LPAR2 and server.xml. LPAR2
7. Stop the MUF and CA Datacom Server on the current LPAR1.
8. Duplicate the corresponding files for LPAR2 and rename them to their original names: context.xml and server.xml
9. Start the MUF and CA Datacom Server started tasks or batch JCL on LPAR2.
10. (Optional) Log in to CA CSM running on LPAR2 and navigate to the Settings tab, System Settings, Mount Point Management. Clear the check box Unmount at Shutdown. Click Apply to save your changes.
