Changing values

An installation can change configuration values established by an APPCPMxx parmlib member by creating another APPCPMxx parmlib member containing LUDEL statements that delete previous statements, or the parmlib member can contain LUADD and SIDEINFO statements with new parameter values to modify previous statements. Examples of parmlib members used to delete and modify configurations are in z/OS MVS Planning: APPC/MVS Management.

Note: When modifying previous statements, the parmlib statements have a cumulative effect, and any one parmlib member might not reflect the current configuration.

In addition to the SET APPC command, the SETAPPC command allows the installation to perform the same functions, but without having to update the APPC parmlib member. See z/OS MVS System Commands for further information.
