XES Control File Placement

You use the XESFILEID and STRNAME parameters on the ALLOCATE command to allocate any new coupling facility structure control file for the use of CA MIM. Use the XESFILEID parameter on the DEALLOCATE command to remove a coupling facility structure control file from the use of CA MIM.

To allocate a XES control file

1. Issue the following command to determine the next available control file number:

   DISPLAY FILES 
   

   See the following note regarding pre-defining a coupling facility list structure.

2. Issue the following command on all systems in the MIMplex:

   ALLOCATE XESFILEID=nn,STRNAME=newstructure
   

   nn

   Specifies the number of the new control file.

   newstructure

   Specifies the name of the coupling facility structure to be used as a CA MIM control file

3. Reissue the following command to confirm that the new file was added to the control file list.

   DISPLAY FILES
   

Notes:

• You must have defined the coupling facility structure, MIMGR#TABLE02, in a policy in the CFRM (Coupling Facility Resource Management) couple data set, and the policy must have been previously activated.
• For detailed information regarding the activation of a CFRM policy, see the IBM publication Setting Up a Sysplex.
