Understanding the LTM for MVS configuration parameters

This section lists the LTM for MVS configuration parameters in alphabetical order with their valid values. Parameter descriptions include information about performance and tuning considerations where appropriate.

Be sure to read the information in this section before you change configuration parameter values so that you understand the consequences of the changes.

The default values for most of the parameters in the LTM for MVS configuration file enable the operation of most replication systems.

You can change parameter values to accommodate unusual environments or situations. For example, you can adjust parameter values if an error message indicates that your system has run out of configurable resources.
