::allocate
However there;s a lot of memory on server

You mention you are using:

openjdk version "11.0.18" 2023-01-17 OpenJDK Runtime Environment Temurin-11.0.18+10 (build 11.0.18+10) OpenJDK 64OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9.1+1, mixed mode)_

But I see two separate versions there 11.0.18 and 11.0.9

[drayper]

Yes i tried with either one and cannot get app to install , it installs with Ibm Sereum Java 11

Noting a recent PMC discussion, for AIX 7.1 EOL

FYI @sxa

[karianna]

Is it possible to move to https://www.ibm.com/docs/en/aix/7.2?topic=aix-release-notes AIX 7.2.5 - I believe 7.2.0.0 is EOL

[drayper]

Hi Martin , yes this is is in process should have Server upgraded to AIX 7.2.5 Monday or Tuesday then will retry install with Adoptium 11.0.18 . Delete the 11.0.9 Java from server only tried this to see if issue was 11.0.18

[drayper]

Updated to AIX 7200-05-04-2220 and still failed with not enough memory but system has 5.8 GB free memory

@drayper Do you have a sample app that we can use to reproduce this with? Our tests suites didn't show any problems on 7.2.
Also if you don't already have it can you run

export LDR_CNTRL=MAXDATA=0x80000000

In the environment before starting the app to see if that makes a difference.

I have one further question - you said earlier that it Works with Oracle Java 8 or IBM Serum 11.0.17.0 - I don't believe Oracle has a JDK for AIX - can you confirm whether it was AIX systems that it works on or another platform?

[drayper]

Thank you so much the (export LDR_CNTRL=MAXDATA=0x80000000) command did the trick. I'm running tests to ensure all is working , but now i can since it installs. Do you thinks this is a problem with the JAR from the vendor ?

[sxa]

Not really - it's related to AIX memory management and not specific to java or any particular application so not something your vendor's application is likely to be able to take any action to fix (unless they wanted to document the use of that option, or rewrite their app to use less memory!)
I'm sure I've seen an article on the IBM pages that had some details which I was going to point you to, but I can't find it right now, so https://knowledge.broadcom.com/external/article/55881/increasing-memory-usage-on-aix.html covers what it's doing. hope that clarifies things.

[drayper]

Thanks for your help . I'll close this issue with a comment that in ulimit on AIX DATA should be set to unlimited to the root process for Adoptium
