ISG log gets too huge in no time on EBS R12.2 with SOA gateway environment

Hello All, Greetings !!

We have implemented ISG in our EBS R12.2 environment and enabled file logging for REST services.

The size of the ISG log file becomes pretty huge in no time as the volume of ISG calls is high and also each and everything is logged in the file.

Is there a way to rotate these logs without bringing down the instance OR reduce the amount of log written like write only when there is a failure ?

Configuration :

Under $INST_TOP/soa/isgagent.properties,

<SID>.ISG_GLOBAL_LOG=TRUE

<SID>.ISG_LOGGER=FILE

<SID>.ISG_TEMP_DIRECTORY_LOCATION=/U01/12.2/fs_ne/ISG_TEMP/
