Collecting extended data

You can use the DCIOAL, EMIOAL, FFIOAL, and FPIOAL parameters in BBPARM member IMFBEX00 to control the maximum length of the I/O area copied into the detail trace for specific call types.

The default for each parameter is 64 bytes of data, and the maximum length you can specify is 65536. If you specify 0 for a parameter, no I/O area data is captured for that data type.

For information about the BBPARM IMFBEX00 member, see the MainView for IMS and MainView for DBCTL Customization Guide. To determine the current settings in IMFBEX00, use the IBEXSUMR view.

Note

Your changes affect all detail traces, not just the new trace.

To change the I/O area parameters

  • Make the parameter changes in BBPARM member IMFBEX00.
  • Issue the reset command .E PARM IMFBEX00.
  • Start a new detail trace.
