Changing the limiting of SYSOUT lines

If you specify a SYSOUT class instead of OUTDATASET, you can change whether DFSMShsm limits the lines of SYSOUT or specify what that limit is by using the following patch:

PATCH .MCVT.+1BD X'3D0900'  /* Limit SYSOUT size to 4 million lines */

The maximum allowable value is 16777215 (X'FFFFFF'). If you specify X'000000', DFSMShsm does not specify limiting for SYSOUT; the result is determined by how your JES2 or JES3 system is set up. For more information, see z/OS JES2 Initialization and Tuning Reference or z/OS JES3 Initialization and Tuning Reference.

If you specify a nonzero value, it must be greater than or equal to the DFSMShsm default limit of 2000000 (X'1E8480') lines; otherwise, DFSMShsm uses that default limit.

Note: If you use a limiting value (including the default), but a SYSOUT data set exceeds that limit, the system cancels DFSMShsm.
