MLPA

MLPA={aa                     }
     {(aa[,L][,NOPROT])      }
     {(aa,bb...[,L][,NOPROT])}

This parameter specifies one or more IEALPAxx parmlib members, which list modules to be added to the pageable LPA, as a temporary LPA extension.

The two characters (A-Z, 0-9, @, #, or $) represented by aa (or bb, and so on), are appended to IEALPA to form the name of the IEALPAxx members. If the L option is specified, the system displays the contents of the IEALPAxx parmlib members at the operator's console as the system processes the members.

The LPA modules in the IEALPAxx parmlib members are page-protected in storage, by default. If an attempt is made to store into a page-protected module, a protection exception occurs. However, the NOPROT option allows an installation to override the page protection default. When NOPROT is specified, the LPA modules in the IEALPAxx parmlib members are not page-protected.

The installation can use the MLPA parameter to temporarily modify an existing LPA at a quick start or a warm start IPL (without creating a new LPA through the CLPA parameter). The added modules are temporary in that they remain as an LPA extension only for the duration of the current IPL. The temporary modules will not be automatically reinstated by a quick start or a warm start IPL. That is, the MLPA parameter must be specified again in the next IPL to reinstate the modified LPA.

If the installation wants to retain the temporary modules as a permanent part of the LPA, it should use the IEBCOPY utility or the linkage editor to place the modules in a data set that is part of the LPALST concatenation, and specify the CLPA and LPA parameters at a future IPL to load the specified LPALST concatenation into the LPA.

For more information about the MLPA option, see IEALPAxx. For information about the fixed LPA option, see the FIX parameter and IEAFIXxx (fixed LPA list).

Value range: Any two characters (A-Z, 0-9, @, #, or $), repeated if desired.

Default: None If MLPA is not specified, no modified LPA is created.

Associated parmlib member: IEALPAxx
