Specifying Index and Data Buffers

Specifying Index and Data Buffers

REOPEN command

By default, the EPILOG reporter opens the EDS with three data buffers and two index buffers. There are circumstances in which the reporter might operate more efficiently if the number of VSAM data and index buffers is increased. This can be done with the REOPEN command, which accepts the following keywords:

BUFND BUFNI

Number of data buffers Number of index buffers

For example, the command REOPEN BUFND(5) BUFNI(7)

closes and reopens 5 data buffers and 7 index buffers in the VSAM cluster using the buffer specifications you have requested.

After the VSAM cluster is reopened, the INQUIRE SUMMARY display (Figure 27 on page 103) appears.
