BLKSIZE

The Command Line Interface › Creating a File on an IBM Mainframe › BLKSIZE

BLKSIZE

Specifies the block size of a data set created on an IBM mainframe.

Note: Used when FILE_OPTION=CREATE

Range: 0 to 32767

If the format is…	Then the block size must be…
Fixed or fixed block record	A multiple of the record length
Variable record	Four bytes larger than the record length
Undefined record	Larger than the largest record length

Default: 800

COMPRESS_PDS

The compress_pds parameter controls when a PDS dataset gets compressed for CA XCOM Data Transport z/OS partners that support this functionality. The value of the CMPRS_PDS_ALLOW parameter in the z/OS default table (XCOMDFLT) or destination member (XCOMDFLT) determines if PDS compression is allowed. When this parameter is set to YES, then PDS compression can occur on the CA XCOM Data Transport z/OS partner.

NONE: Suppresses the compression of an output PDS dataset as part of a CA XCOM Data Transport transfer.
BEFORE: The output PDS dataset is compressed before the transfer of user data begins.
AFTER: The output PDS dataset is compressed after the transfer of user data has completed.
BOTH: The output PDS dataset is compressed both before and after the transfer of user data.

Default: NONE

Note: COMPRESS_PDS applies only to PDS data sets that are opened for output as the target of a CA XCOM Data Transport transfer.

CREATEDELETE

Specifies whether an existing data set can be deleted and a new data set allocated at the start of a FILEOPT=CREATE transfer. This functionality is for CA XCOM Data Transport z/OS partners with support for CREATEDELETE. The CREATEDELETE parameter in the z/OS default table (XCOMDFLT) or destination member (XCOMCNTL) specified by the z/OS CA XCOM Data Transport Administrator affects the functionality of this parameter.

When z/OS has CREATEDELETE=ALLOW:

YES: If FILEOPT=CREATE and the data set exists, then the data set is deleted and a new data set is allocated at the start of the transfer.
NO: If FILEOPT=CREATE and the data set exists, then the transfer fail with a catalog/file error.

When z/OS has CREATEDELETE=YES:

YES or NO: If FILEOPT=CREATE and the data set exists, then the data set is deleted and a new data set is allocated at the start of the transfer.

When z/OS has CREATEDELETE=NO:

YES or NO: If FILEOPT=CREATE and the data set exists, then the transfer fails with a catalog/file error.

Default: NO

Notes:

The attributes of the existing dataset are deleted and the new data set is allocated with the attributes specified in the transfer when CREATEDELETE=YES.
CREATEDELETE applies only if the target data set is a sequential data set or an entire PDS/PDSE. CREATEDELETE is ignored for other types of data sets (such as PDS members, PDSE members, VSAM, and USS files).
CREATEDELETE applies to relative GDGs when the dataset is specified using the fully qualified GxxxxVxx name.
