IMS External Subsystem Commands

IMS External Subsystem Commands

Use the IMS external subsystem commands to perform the following tasks:
  • Temporarily override the CCERR parameter in the EDMSDIR default options module. Usually, the CCERR parameter is set to ABORT in the EDMSDIR default options module. You might need to override this default setting if the PowerExchange Logger becomes unavailable and you cannot resolve the problem promptly. In this case, issue the
    x
    EDP-CONTINUE command to restart your IMS online transactions. The transactions can then run while you are resolving the problem.
  • Generate a report on the change data capture activity of the IMS ECCR. You can print the report to the EDMMSG SYSOUT data set or the job JESMSGLG log of the IMS region. From the report, you can determine the databases for which PowerExchange is capturing changes. The EDMMSG data set contains messages that are sent from the Log Read API after it connects to the PowerExchange Logger to read captured change data.
To issue these commands to the IMS external subsystem from the IMS console, use the IMS /SSR command. In each command, replace the
x
variable with the command recognition character (CRC) that you specified when configuring the IMS external subsystem for the ECCR. If you do not know the CRC, you can run the DISPLAY SUBSYS command.
You can issue IMS external subsystem commands only if you edited the appropriate SSM member in the IMS PROCLIB library to supply a command recognition character (CRC) for the subsystem definition that PowerExchange uses.
