Define File Groups

To define a file group, include the GROUP parameter on an ADDFILE command. For example, to place the JRNL1 file under the management of CA-L-Serv and to associate it with file group UGRPID, specify this command in the CA-L-Serv parameter data set:

ADDFILE JRNL1 GROUP(UGRPID)

To add subsequent files to the group, issue an ADDFILE command specifying the same group ID for each file you are adding to the group.

These file management options must be identical for files in the same group:

• They must all use the same buffer pool. (That is, the value for the POOL parameter must be the same for all of those files.)
• If you specify OPTION(DEFER), OPTION(APPEND), or OPTION(TRIM) for one file in the group, specify that value for all files in the group.
