Hi, This is an IBM document for diagnosing the SHRLIBRGNSIZE issue, which includes a tool for analysis.
One key aspect to watch out for is whether multiple releases of Java shared libraries are being loaded in USS, as that was the root cause in our case. Hope it helps,https://www.ibm.com/support/pages/system/files/inline-files/WP101320_-_SHRLIBRGNSIZE_and_Effect_on_31-Bit_JVM_Storage_Needs.pdf Regards,Jasi Grewal. ------------------------------------------------------------------------------------------------------------------------------------------------------ On Wednesday, February 26, 2025 at 03:03:56 p.m. EST, Jousma, David <[email protected]> wrote: Here is some info that might be helpful: https://community.bmc.com/s/article/BPXI039I-SYSTEM-LIMIT-SHRLIBRGNSIZE-HAS-REACHED-95 Dave Jousma Vice President | Director, Technology Engineering From: IBM Mainframe Discussion List <[email protected]> on behalf of Lindy Mayfield <[email protected]> Date: Wednesday, February 26, 2025 at 2:01 PM To: [email protected] <[email protected]> Subject: What it means when D OMVS,LIMITS SHRLIBRGNSIZE is at Max Usage Hi, On my test system I have the following values for SHRLIBRGNSIZE from D OMVS,LIMITS for SHRLIBRGNSIZE: CURRENT HIGHWATER SYSTEM SHRLIBRGNSIZE 0 67108864 67108864 But on another system I see: SHRLIBRGNSIZE 67108864 67108864 67108864 The Current is equal to the System. What would you do if you saw that SHRLIBRGNSIZE was full on your system, and at the same time somewhere else there were sporadic memory issues with LE and System SSL? Could they be related? Thanks for any help or guidance.
