Hi Herman & David,
we have followed the "trace activated at runtime" part SAP Netweaver 04s
"Please start <SAP J2EE 700 InstallDir> \usr\sap\<SID> \<InstID>\j2ee\admin\go.bat and login to your cluster. Then please navigate to your Server<Node#> -> Services -> JCo RFC Provider. On the tab page "Special Settings" for each RFC listener ID you will find the appropriate tracing options for JCo, RFC (JRfc) and CPIC traces. After choosing the desired tracing and tracing levels you have to press the "Set" button."
this is the only change that we have done in visual admin as mentioned here and later we reverted it back too but still its continuing to generate trace files.we tried to take a system restart but that to didnot help.
Thanks & Regards,
Rajdeep
