ACMEMnn statements

Usage

If you use the TRACE subcommand, OMEGAMON for Db2 PE temporarily uses an ACMEMnn work data set for each Db2 member that occurs in the input records. For example, if the input data set contains, or data sets contain, data from three different members, the ddnames ACMEM01, ACMEM02 and ACMEM03 are used. The work data sets are normally created on the MVS-defined work volumes, and on completion of the task.

Usage notes

• Only include ACMEMnn in your JCL if you want to control the placement or size of the data set. If your input has a large amount of data for a specific member, you might get a B37 abend on the ACMEMnn work data set. In that event, specify ACMEMnn.
• OMEGAMON for Db2 PE allocates 68 MB for a work data set by default. Define it as a temporary data set. As a guide, if the number of accounting-related input records for a specific member that satisfy the GLOBAL and ACCOUNTING command criteria exceeds 40 000, specify ACMEMnn.
• Do not specify DUMMY or DISP=MOD for this data set.
