While running complex queries the /tmp filesystem is heavily used by the Database Gateway for SQL*Server (DG4MSQL) processes.
Use the following unix commands to verify the usage -
- ps-ef |grep dg4msql
>>>> take note of process id (PID)
- for each PID found with the above command check file descriptors used by the relevant processes -
ls -l /proc/PID_x/fd
- and check file names in /tmp
- while leaving dg4msql running check size with -
ls -l /tmp
On Windows systems, the impacted file system are \temp or the directory specified in user/system enviroment variable as TEMP.
The issue was introduced with 188.8.131.52-184.108.40.206
