Use the DTLCUIML utility to write user-defined records to the IMS log. When the IMS log-based ECCR encounters one of the user-defined records, it triggers a message in the PowerExchange Logger to create a marker in the change stream for the affected registration tags.

The tokens represented by the marker can be used to define the start point for an extraction in the PWXPC restart token file or in the DTLUAPPL utility for ODBC extractions.

There is no limit or restriction on the number of markers being set in the change stream. The IMS log record ID chosen has to be unique for the individual installation. Specify the IMS log record ID chosen in the RECID parameter for the IMS log-based ECCR.

The utility runs as a standard IMS application program. There is no need to provide a specific PSB. The utility can use any PSB as long as the first PCB in the PSB is an IOPCB. The utility uses the IMS LOG Call to write IMS log records.

This utility must run as an IMS BMP job. This ensures that the IMS log record is written into the IMS logs and that the associated log is read by the IMS log-based ECCR. Sample JCL is supplied in member IMSLOGW in the RUNLIB library.
