Technical Notes › Use the Module Reload Feature

Use the Module Reload Feature

The module reload feature (also called continuous operation enhancement) enables you to load a new copy of a CA OPS/MVS module on a running system.

To use the module reload feature

Issue the z/OS MODIFY command in one of the following forms:

MODIFY ssid,RELOAD(modname)
F ssid,RELOAD(modname)

ssid

Specifies the CA OPS/MVS subsystem ID (for example, OPSS)

modname

Specifies the name of the CA OPS/MVS module being reloaded (for example, OPJ2CB).

You can use the module reload feature to load new copies of the JES2 offsets module (OPJ2CB) and user exit (OPUSEX) without recycling CA OPS/MVS. You can also use it to apply selected module maintenance, with some restrictions.

When you replace a module, CA OPS/MVS retains the old copy of it until CA OPS/MVS terminates. If you use the module reload facility often, product ECSA usage may increase.

Note: The output from an OPSPARM command or OPSPRM function for a product module includes a line of output, the last line of output for each module displayed, that indicates whether the module is eligible for dynamic reloading.
