IMS monitor reports with DBCTL

A summary of the DBCTL-related data in IMS monitor reports. This information also applies if your CICS® system is connected to an IMS DM/TM system to obtain DBCTL support.

IMS monitor reports that apply to DBCTL

  • Call summary
  • Program I/O
  • DB buffer pool
  • VSAM buffer pool
  • Program summary
Note: In a DBCTL environment, interpret the terms program and transaction in these reports as PSB and PSB scheduling, respectively.

IMS monitor reports that apply partially to DBCTL

  • Region summary
  • Region IWAIT

    (An IWAIT occurs when a DBCTL request causes I/O activity. IWAIT time denotes the time DBCTL spends waiting for IMS resources, in addition to the number of I/Os.)

  • Any other region-based reports.
Note: In a DBCTL environment, interpret the term region in these reports as the representation of a CICS thread or a BMP region in DBCTL, but beware that a DBCTL region can represent different CICS threads or BMP regions during a monitor run.
