Hi Naz, Out of memory errors in Java on Z can happen for a number of reasons. It could really be that you've run out of heap space but it could also be that LE has hit a problem with a z/OS limit.
Please can you provide more details about the exception message you get? For instance here's an OOM exception which actually means the MEMLIMIT of the address space is not large enough. java.lang.OutOfMemoryError: Failed to create a thread: retVal -1073741830, errno 132 (0x84), errno2 -1055784930 (0xc112001e) Kind Regards, Mark --------------------------------------------------- Mark Hiscock z/OS Connect Phone: (+44)1962 818662 Email: mark.hisc...@uk.ibm.com --------------------------------------------------- From: Nazih Noujaim <ngnouj...@mmm.com> To: IBM-MAIN@LISTSERV.UA.EDU Date: 04/06/2019 14:27 Subject: Out of heap space while invoking a jar java8 but works fine when invoke the jar when run in java7 using Ent Cobol 4.2 Sent by: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> HI Everyone I have an OO Cobol program that invokes a jar on USS using java v1.8, 31 bit. When I run over 250K calls, it runs out of memory. If the jar is created in java 7 and I compile/link/run the OO cobol pgm in Java 731, it runs fine. I saw that there was some problems back in java 5 in the IBM sdk with OOM and was fixed but nothing recent. Is anyone aware of any similar issues with java 1.8? Is there any update to the JNI copy book whether you use v7 or v8? Any different options in the JVM setup/Installation that I should ask about? Here is my calling order: NewStringPlatform Invoke GetStringPlatform 2 DeleteLocalRef calls for the input and return string. I haven't been able to find any links on diffs between 7 and 8?
