Issue/Introduction

Setting up CICS to use LLA gets an ACF2 violation ACF99913 for a dataset.   During CICS initialization the log shows:

ACF99913 ACF2 VIOLATION-04,09,CICSTEST,VOLXXX,CEE.SCEERUN2,N/A        
CSV244I CSV UPDATE ACCESS DENIED. USER=CICSTEST CLASS=FACILITY

 AB/S0023 AB/UAKEX ADRS/0000FFFF                                      
+DFHDU0201  CICS1   ABOUT TO TAKE SDUMP. DUMPCODE: LD0001  , DUMPID:

Cause

The CICS region system initialization table (SIT) parameter LLACOPY is set to YES. Therefore, the CICS region user ID is issuing an MVS library lookaside (LLA) operator command but it does not have sufficient authority for the command to be run.

Resolution

CICS needs WRITE access to the dataset for validation:

$KEY(CEE)
  SCEERUN2 UID(uid string of CICS region) R(A) W(A) E(A)
