Creating or modifying a trace table

A trace table is a storage area that Job Optimizer uses to keep trace information about the MainView Batch Optimizer Subsystem.

Use the BSL TRTABLE command to create or modify a trace table in the Extended Common Storage Area (ECSA). This command creates a trace table if one does not currently exist. Use the MODIFY parameter to set or change the table size.

To create or modify a trace table

Enter the following command:mbos BSL TRTABLE [MODIFY nnnn | RESET | DELETE]

  • mbos- The subsystem ID of the MainView Batch Optimizer Subsystem that is active on the MVS image.
  • nnnn - The number of entries in the trace table. Valid values are 255 to 65535.

Value

Description

MODIFY nnnn

Creates the table of a given size (nnnn) in ECSA
For example, issuing the MBOS BSL TRTABLE MODIFY 65000 command creates a 4 MB ECSA table.

RESET

Clears all entries in the trace table

DELETE

Frees the trace table

Note

(PTF BPB1554 applied) During initialization, the BSL TRTABLE command creates a 1-MB trace table. After you apply this PTF, the BSL$NTRC DD statement in the MainView Batch Optimizer Subsystem prevents creating the default trace table.
