Dear sap:
our dev,qas,and prd systems's global filesystem are full,
The nnnJOBLG and nnnBDCLG derectory are very large,
I want to delete those unnecessary files,But I don't know how to do
this,
I have read "note 16513 - File system full - what can you do?"，
but this note did not provide a detailed solution，please help
me,thanks.

Dear Customer,

The job log is saved under /usr/sap/QSB/SYS/global/JOBLG.
In order to clean up the useless job log file under
/usr/sap/QSB/SYS/global/ JOBLG, you should schdule and run
housekeeping SAP standard job SAP_REORG_JOBS(program RSBTCDEL

It is possible that there are some job logs are not for any job.? you
can refer to following sap notes, using RSTS0043 report to delete the
"orphaned" job logs.
