Grouper Users - Open Discussion List

[Shilen Patel <>]

Does it help if you do the following before running gsh?  (Change the path to some place else.)

 

export GSH_JVMARGS="-Dlibrary.jansi.path=/some/other/temp/path/with/exec"

 

Thanks!

Subject: [grouper-users] Re: GSH error after applying API patch 83

 

 

Okay, I found the underlying problem. We routinely mount /tmp with the noexec option, so that's what's causing the failure. Grouper probably shouldn't be trying to exec stuff from /tmp, though. That goes against the CIS security benchmark.

My standalone dev box is RHEL7.4, using Oracle java 1.8.0_151. When I patched the grouper api yesterday, I started getting errors when trying to run an interactive gsh. Thinking it was just a crufty dev environment, I tried a fresh install and am still getting the same error. So I redid the fresh install up to patch 82 (where the dev install had been prior to yesterday), and gsh on the fresh install works fine. After applying patch 83 it starts to throw the error again. Below is the stack trace of what I'm getting. I'm not sure if it's a RedHat thing or an oracle java thing, but whatever it is doesn't seem to happen in the tier container version (built using CentOS7 & openjdk zulu).
