Is there no way to point either JVM, or WLP to a directory other than /tmp? No parameter settings exist?
This is not something that can feasibly be addressed.
The Cognos Anlaytics' Compute Service was built using Apache Hadoop and Spark, and they both have platform-specific native libraries that are extracted to temp directory on startup (we cannot change this behaviour). The OS requires shared libraries to exist on a mount point with exec permission. The noexec flag prevents the native code to be linked into the JVM at runtime, causing the failure when these libraries are first touched (typically the first query to Compute Service).
Hello, we've installed a Cognos Analytics system on premises in a large organization that currently enhances/reinforces security on unix/linux system and demands that the /tmp FS be mounted in no-exec mode. We currently have a derogative rule but a future team may decide to revoke it.
We try to avoid to alter the snappy path directly into the code as it would not be maintained by cognos and could have undesirable side-effects which we can not anticipate.
We need a better, Cognos-managed option allowing us to run the snappy.so in another, non-system location with similar effects to secure the run of our Cognos systems.
Thank you
