Authorizing access with the MVS library lookaside (LLA) facility

If you are using the library lookaside (LLA) facility of MVS™, you can control a program's ability to use the LLACOPY macro.

Authorize the CICS® region's userid in one of the following ways:

It must have UPDATE authority to the data set that contains the LLA module.
It must have UPDATE authority in the FACILITY class to the resource CSVLLA. datasetname, where datasetname is the name of the library that contains the LLA module. For example:
```
RDEFINE FACILITY CSVLLA.datasetname UACC(NONE) NOTIFY
PERMIT  CSVLLA.datasetname CLASS(FACILITY) ID(....) ACCESS(UPDATE) 
```
