COMPRESS_PDS

COMPRESS_PDS is the parameter that causes the actual PDS compression to happen. If your CA XCOM Data Transport administrator has enabled the programmatic PDS compression feature in a CA XCOM Data Transport region, you can use the COMPRESS_PDS option to control if and when output PDS data sets get compressed as part of the transfer.

NONE

Suppresses the compression of an output PDS dataset as part of a CA XCOM Data Transport transfer.

BEFORE

Compresses an output PDS dataset before the transfer of user data begins.

AFTER

Compresses an output PDS dataset after the transfer of user data has completed.

BOTH

Compresses an output PDS dataset both before and after the transfer of user data.

Default: NONE

Notes:

• COMPRESS_PDS applies only to PDS data sets that is, or have been, opened for output as the target of a CA XCOM Data Transport transfer.
• If the COMPRESS_PDS option is present in the DEST member for a particular transfer partner, and that DEST member is made available to the XCOMJOB utility that is used to schedule a transfer to that partner, it becomes the default value for all transfers initiated with that partner CA XCOM Data Transport in that invocation of XCOMJOB.
• If your CA XCOM Data Transport administrator configures CMPRS_PDS_ALLOW=YES or CMPRS_PDS_ALLOW=X37, the COMPRESS_PDS=NONE option cannot suppress the compression of an output PDS data set if a z/OS system abend B37, D37, or E37 occurs.

Output

Output from the compression utility is handled in accordance with the setting of the CMPRS_SYSOUT_CL server-level parameter. The spool data sets (if they are allocated) will have the following prefixes:

• XB for compressions performed before a transfer, as in the case with COMPRESS_PDS=BEFORE or on a restarted transfer request
• XA for transfers performed after a transfer

The decimal transfer request number is appended to the prefix to provide a unique spool entry for each compression operation. This naming convention allows for the correlation of compression utility output with a specific file transfer if there is a need for problem determination research after the transfer.

Example:

For a request number 034271, the following spool entry names would apply:

• The output from the utility used to compress the PDS data set before the transfer would be named XB034271.
• For a compression performed after the data transfer, the SYSOUT dataset would be named XA034271.

EATTR

This parameter identifies if the dataset can have extended attributes when the dataset is allocated on an Extended Address Volume (EAV).

OPT

Specifies that a dataset can optionally have extended attributes.

NO

Specifies that a dataset cannot have extended attributes.

Default: None

Note: This parameter is applicable only for data set creation on an IBM mainframe.
