Where:

  • DISKBUFF returns the statistics for both above-the-line and above-the-bar buffers.

  • DISKBUFFG returns the statistics for the above-the-bar buffers.

  • DISKBUFFL returns the statistics for above-the-line buffers.

Example

MONITOR DISKBUFF

or

MONITOR DISKBUFFG

Usage notes

  • The MONITOR DISKBUFF command displays the following types of information, in the format presented below, where FCT is the number of pages in the File Control Table:

    MONITOR DISKBUFF FILENAME FCT TBLA TBLB TBLC TBLD TBLE TBLX *TOTAL* -------- --- ------ ------ ------ ------ ------ ------ ------- CCATEMP 0 40 0 0 0 0 0 40 PROC1 1 0 0 0 11 0 0 12 FILETBLX 1 1 10 0 2 0 2 16 TESTZ 1 1 11 0 3 185 0 201 *TOTAL* 3 42 21 0 16 185 2 269

  • The MONIOR DISKBUFFG command displays above-the-bar buffer pool usage:

    MONITOR DISKBUFFG FILENAME FCT TBLA TBLB TBLC TBLD TBLE TBLX *TOTAL* -------- --- ------ ------ ------ ------ ------ ------ ------- CCATEMP 0 3 0 0 0 0 0 3 CCAGRP 1 0 0 0 1 0 0 2 CCASYS 1 1 7 8 15 0 0 32 EWDPROC 1 0 0 0 3 0 0 4 EWDSCR 1 0 0 0 1 0 0 2 EWDDATA 1 0 0 0 1 0 0 2 FILETBLX 1 0 0 0 2 0 0 3 *TOTAL* 6 4 7 8 23 0 0 48

  • The MONITOR DISKBUFFL command displays below-the-bar buffer pool usage.

    MONITOR DISKBUFFL FILENAME FCT TBLA TBLB TBLC TBLD TBLE TBLX *TOTAL* -------- --- ------ ------ ------ ------ ------ ------ ------- CCATEMP 1 3 0 0 0 0 0 3 CCAGRP 1 0 0 0 1 0 0 2 CCASYS 1 1 0 0 11 0 0 13 EWDPROC 1 0 0 0 3 0 0 4 EWDSCR 1 0 0 0 1 0 0 2 EWDDATA 1 0 0 0 1 0 0 2 FILETBLX 1 0 0 0 2 0 0 3 *TOTAL* 6 4 0 0 19 0 0 29
