Defining Independent Files
Defining Independent Files
== Partition SYSLOG ID
CA Dynam lets you use certain ID codes to define independent files. The
following describes how these ID codes provide protection for both partitionindependent
and CPU-independent files:
• Partition IDs ensure the uniqueness of File IDs across multiple partitions,
Volume serial numbers for a particular partition, or both.
• CPU IDs ensure file uniqueness among different CPUs in a multi-CPU
environment.
When these files are processed, CA Dynam/D substitutes the appropriate ID of
the partition, CPU, or both, to replace the ID code you supplied. All the codes
supported for this function, and their substitutions, are shown in the table
below:
=== Partition SYSLOG ID and CPUID character

JCL-Defined Partition and CPU Independent Files
This section describes the JCL defined partition and CPU independent files.
Multi-Partition Files
File Uniqueness:
To ensure file uniqueness across multiple partitions, enter the partition ID
code on the DLBL statement in the format illustrated below:
// DLBL filename,'==.file-id',...
When the file is processed, CA Dynam/D will replace the two equal signs
('==') with the partition (BG, F1, F2, and so on) in which the job is running.
