Issue/Introduction

On the Data Aggregator and on the Data Collectors the activemq, dadaemon, and dcmd script files change their ownership to root after a reboot even when the application is properly shut down.

This cause at least an extra 2 hours of down time last night bringing the servers up after a scheduled patch reboot.

Need to stop these files from changing owners to reduce our down time. 

Environment

Release : 21.2

Component : IM Data Aggregator

Cause

Currently, if the DA/DC doesn't shutdown cleanly and remove .lock, AND it's running as NON-root,

there is an issue (fixed by 21.2.8) where it recreates the data directory as root and DA/DC can't write to it as non-root.

Resolution

workaround until 21.2.8 would be to edit scripts/karaffunctions on DA/DCs..
find checklockandcleanup function.
change:

        if [ ! -e $karaf_root/data ]; then

            # We need to create the karaf.out file as startup fails instead of creating it

            mkdir $karaf_root/data/;

            touch $karaf_root/data/karaf.out;

        fi

to:

        if [ ! -e $karaf_root/data ]; then

            # We need to create the karaf.out file as startup fails instead of creating it

            mkdir $karaf_root/data

            touch $karaf_root/data/karaf.out

            chown -R <installuser> $karaf_root/data

        fi

And:

        if [ ! -e $karaf_root/deploy ]; then

            mkdir $karaf_root/deploy/;

        fi

To:

        if [ ! -e $karaf_root/deploy ]; then

            mkdir $karaf_root/deploy/

            chown -R <installuser> $karaf_root/deploy

        fi

 

replace <installuser> with whoever is running/owns the DA/DC install dir

Additional Information

This will be fixed in 21.2.8 by adding code to chown the directories to the non-root owner.
