TataPlay Fiber - Troubleshooting High Utilization of /U01 Partition and Pending Files on CGF/Mediation Server

Overview

The TataPlay Fiber customer is experiencing two main issues. The first issue is the high disk space utilization of the /U01 partition on their server, which has reached 90% capacity. The second issue is related to pending files on a specific path on the server, which are not being processed as expected. 

Solution

To resolve the high utilization of the /U01 partition on the server, the purging script needs to be run with an increased ulimit value. The script is usually located at /opt/stlmediationsetup/script/raw_purge.sh and is designed to delete data that is 8 and 10 days old. The command to run the script with an increased ulimit value is:

ulimit -s 1000000;sh  /opt/stlmediationsetup/script/raw_purge.sh

For the issue of pending files on a specific path on the CHN COL1 server, the distribution service needs to be restarted. The steps to do this are:

1. Navigate to the path cd $CRESTEL_P_ENGINE/module/mediation/config/8405/service/distributionservice/ (change 8405 to the port being used)
2. Copy the contents of the folder 000/ to a new folder named 001/
3. Inside the 001/ folder, update the service path in the distribution-service.xml file to the location where the backlog is present using the vi command.
4. Restart the service by running sh $CRESTEL_P_ENGINE/module/mediation/bin/startServer_8405.sh ( change 8405 to the port being used)

Summary

By increasing the ulimit value and running the purging script, the high utilization of the /U01 partition on the server can be resolved. The issue of pending files on the CHN COL1 server can be resolved by restarting the distribution service following the steps provided.
