Parameters

BERTFREE

The current number of free BERT entries.

BERTNUM

The number of BERT (Block Extent Reuse Table) entries defined in the checkpoint.

BERTUSE

The types of control blocks in BERTs and the number of BERTs used by each control block type.

BERTWARN

The threshold of BERT utilization at which the $HASP050 message should be issued.

CKPT1=(CAPACITY|UNUSED)

Displays information about the number of 4K records in the checkpoint data set.

CAPACITY: The maximum capacity of the CKPT1 data set in 4K records.
UNUSED: The number of 4K records that are unused by the CKPT1 data set.

CKPT2=(CAPACITY|UNUSED)

Displays information about the number of 4K records in the checkpoint data set.

CAPACITY: The maximum capacity of the CKPT2 data set in 4K records.
UNUSED: The number of 4K records that are unused by the CKPT2 data set.

Authority Required

This command requires display authority.

This command requires read security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide, SA32-0991.
