Error description
ECSA storage management improvement for both IRLM 220 & 230
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All HIR2220 (IRLM220) and HIR2230 (IRLM230) * * users. * **************************************************************** * PROBLEM DESCRIPTION: MSGDXR175E IRLM is unable to obtain * * storage - ECSA may appear on console * * followed by IRA100E for SQA shortage. * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** In a system running low on ECSA storage, the virtual storage manager may return a storage block below the 16M line when GETMAIN is called with option LOC=ANY. IRLM could accumulate CSA storage blocks in a short period of time causing CSA to fill up. This can happen typically with monitoring tools sending Query or Notify requests in a data sharing group. IRLM may not be able to quickly release the CSA/ECSA storage as it could run storage compression only at deadlock detection timer intervals which may not be aggressive enough to handle a spike of incoming NOTIFY or QUERY requests. This may lead to MSGDXR175E and/or IRA100E to be issued.
Problem conclusion
This APAR improves CSA/ECSA storage management in IRLM. IRLM will not be acquiring any CSA storage below the line, and storage compression will be triggered sooner if MVS is unable to return the requested block size from ECSA.
