TRTRANSZ

The TRTRANSZ system initialization parameter specifies the size, in kilobytes, of the transaction dump trace table.

Defining TRTRANSZ

You can define the TRTRANSZ system initialization parameter in the following ways:
  • On the PARM parameter of the EXEC PGM=DFHSIP statement
  • In the SYSIN data set of the CICS® start up job stream
  • Through the system console
  • In the DFHSIT macro

Values for TRTRANSZ

Valid values for the TRTRANSZ system initialization parameter are as follows:

TRTRANSZ={1024 | number-of-kilobytes}

When a transaction dump is taken, CICS obtains storage from 64-bit z/OS® storage for the transaction dump trace table.

1024
1024 is the default value for the TRTANSZ transaction dump trace table.
number-of-kilobytes
The number of kilobytes of storage to be allocated for the transaction dump trace table, in the range 1024 KB through 1048576 KB (1 GB).

Trace entries are of variable lengths. The average length of a trace entry is approximately 100 bytes. 1 KB is equal to 1024 bytes.

When you set this system initialization parameter, check your current setting for the z/OS parameter MEMLIMIT. MEMLIMIT limits the amount of 64-bit storage that the CICS address space can use. Your setting for TRTRANSZ must remain within MEMLIMIT, and you must also allow for other facilities in the CICS region that use 64-bit storage. See Estimating and checking MEMLIMIT. For information about MEMLIMIT in z/OS, see Limiting the use of private memory objects in the z/OS MVS Programming: Extended Addressability Guide.
