Post-installation considerations for Linux users
Linux root permissions
On Linux platforms, if Apama is installed by the root user, the resulting Apama work directory will also be owned by root. This can cause problems for non-root users who run Apama tools as they may not be able to write to the work directory. To support non-root users in installations owned by root, do one of the following:
Change the permissions or the owner of the work directory and its subdirectories to allow write access by users.
Define the environment variable
APAMA_WORK and set its value to a work directory for which the users have write access.
Linux core file size setting
Linux systems are often run with their core file size limit set to zero. A consequence of this is that in the unlikely event that the correlator or an adapter crashes, no core file is written, which hinders investigation of the cause of the crash. To avoid this situation, set the core file size to unlimited in the login configuration for each user who runs Apama components.
