GLVSHAREDDD Parameter

The GLVSHAREDDD parameter relates to the OPSHFI command processor and shared file support. The OPSHFI command processor provides you with the capability to store global variable records on an external VSAM key-sequenced data set that can be shared among systems. Using various OPSHFI keywords, you can WRITE variable records to the VSAM file, or READ or DELETE variable records from the VSAM file.

The GLVSHAREDDD parameter specifies the z/OS ddname that you want CA OPS/MVS to use when it allocates this shared VSAM file.

CA OPS/MVS uses the value you specify to form the z/OS RESERVE enqueue name, which is used to serialize access to a file that is shared among systems. All systems that share the VSAM file should use the same ddname.

For related information, see the description of the OPSHFI command processor in the Command and Function Reference.
