VSAM-Buffer-Pool report

The VSAM-Buffer-Pool report gives you processing information about a specific VSAM subpool. One report is produced for each subpool you specify.

For subpools within a VSAM local shared resource pool, reports are produced in ascending order based on subpool buffer size. If both index and data subpools exist in a given shared resource pool, index subpool reports follow data subpool reports. Reports for subpools in different shared resource pools are always produced in the order the shared resource pools are specified. You specify shared resource pools and subpools in control statements processed when IMS is initialized. In a batch system, the control statements are put in the DFSVSAMP data set. In an online system, they are put in the IMS.PROCLIB data set with the DFSVSMnn member name.

The VSAM-Buffer-Pool report has no meaning for HSAM or SHSAM databases, because neither of these databases can use VSAM as the access method.
