Free Up Disk Space

If server disk space issue is being encountered then its time to clean up those files in your Cognos server. We usually encounter errors, such as report saving and exporting to excel, scheduled run fails and even 100% CPU utilization when our server’s disk space usage goes above 90%. The higher the disk usage above 90%, the more the number of errors and the more severe.

Upon checking, these two folders,among others, consume the largest spaces:

\data\cqe\RTModels
\temp

The files in these folders are generated by Cognos to use temporarily when tasks and reports are executed. When a task is terminated abnormally, some of the files do not get deleted. So over time, the contents of these folders can eat up significant server disk space.

To delete files in these folders:

1. Stop the Cognos service.
2. Delete the files in the said folders.
3. Start the Cognos service.

After undertaking this process, our disk space usage went down to 75%. So regular Cognos services restart should be done.
