Overview of PSS options


PSS options control the PSS component.

Warning

Important

You can override the XCF group name and join sysplex group options that you specify on the PSS Options subpanel. To do so, specify an XCF group name on the XBM start command, or specify an XBMGROUP parameter on the XBM PROC.

The following table describes the different options.

Option

Description

Sysplex group name

The name of the XCF group that you want this XBM subsystem to join when the PSS component is started

This name must match the first level of the structure name for the XBM structures that are defined in your CFRM policy. The default is XBMGROUP. Alternatively, you can specify the XCF group name in the XBMGROUP parameter on the XBM PROC. For information about the XBMGROUP parameter, see Starting-the-ISPF-interface.

Join sysplex group when PSS started

Whether this XBM subsystem should automatically join the specified XCF group when you start the PSS component

To have this XBM subsystem join the specified XCF group, first set this option to Yes and then start the PSS component. The default is 2 (No).

Enforce shared repository

Whether all XBM subsystems in the XCF group should be forced to share a single repository

The default is 2 (No).

Sysplex processing time-out

The amount of time in seconds that an XBM data sharing group member should wait for a response from the coupling facility before timing out

This parameter takes effect when you exit the PSS Options subpanel. The default is 60.

Global IO caching allowed

Not applicable for snapshot processing

Remote XBM subsystem time-out

A user-specific value that defines the amount of time (in seconds) that an XBM data sharing group member should wait for a response from the remote XBM subsystem before timing out

The XBM ISPF interface uses this value instead of the global PSS time-out setting when displaying remote XBM subsystem information in the monitors. The valid range for this value is from 1 through 9999 seconds. This value is stored in your ISPF user profile and remains in place until you specify a new value. The default value is 60 seconds.

Warning

Important

This value is directly related to the Remote XBM subsystem size limit option. The higher you set the message size limit, the higher you need to set the time-out value because of the amount of time it takes to process the data from the remote XBM subsystem. If you do not specify an adequate time-out value, XBM might not be able to display the returned information in the ISPF interface. BMC recommends that you adjust these numbers conservatively because they can impact XCF performance.

Remote XBM subsystem size limit

A user-specific value that defines the maximum amount of data that can be returned from any one request to display information in the ISPF interface from a remote XBM subsystem

The valid range for this value is from 99 through 99999 KB. For example, entering a value of 99 limits the amount of information to 99 KB (101,376 bytes). This value is stored in your ISPF user profile. The default value is 4999 KB.

Warning

Important

Ensure that you set this number high enough to process the amount of data that is likely to be returned from the remote XBM subsystem. BMC recommends that you adjust this value conservatively because it can impact XCF performance. Also, ensure that you adjust the Remote XBM subsystem time-out value to a length appropriate for the amount of data you are processing. For each thousand lines of data, XBM requires approximately a 1-MB message size.
