CA Dynam for VSE User Guide

DYNCAT Commands
Enter complete ALLOC information. When ALTER is processed, all the
allocation characteristics are processed. Do not use ALLOC for ISAM files.
Instead, use the PRIME, INDEX, MINDEX, and OVRFL operands. The
parameters provided within the parentheses for ALLOC, PRIME, MINDEX,
INDEX, and OVRFL are positional; substitute a comma for an omitted
parameter unless the comma immediately precedes the closing parenthesis.
BLKSZ=
Optional parameter. Specifies the block size for the file to the CA Dynam/FI
component. The DTF for the file will be modified to the value specified. Valid
entries are:
Maximum blocksize for tape: 65535
Maximum blocksize for disk: 65535, or
OPTimize, or
'OPT,nnnnn' (include single quotes)
When optimal blocking is specified, CA Dynam/FI will recalculate the block size
for the physical device on which the file is being created. For FBA devices, the
CISIZE is recalculated.
The Catalog is updated when the file is closed for output to record the actual
block size used for the file. When the file is opened for input, CA Dynam/FI
must use this value to build the input DTF correctly.
CATOPEN=
Optional parameter. Specifies whether newly opened output versions of this
dataset are to be marked as valid versions so they may be cataloged at OPEN.
This will ensure that the version being created will always be considered a
good version even if it is never closed.
YES
NO
This dataset may be cataloged at OPEN.
This dataset should be cataloged at CLOSE.
CIMSG=
Optional parameter. It changes user-specified messages for the dataset. These
messages will be issued Open Input (OIMSG=), Open Output (OOMSG=),
Close Input (CIMSG=), and/or Close Output (COMSG=) for the dataset, as
specified, and will be directed to the operator console and/or SYSLST as
indicated by the routing code. Routing codes are as follows:
C - Console (default)
P - Printer
B - Both
