Dev_W** trace files

Hello All,

we have totally 8 app servers and 1 CI.

We can get the trace files in ST11.

But can any 1 please let me know how to find out a trace file say Dev_w46 belongs to particular App server.

Or is that all app servers work process number say 46 will be written to trace will Dev_w46.

please suggest.

Regards,

Ravi

      Hi Ravi

      1.Developer traces dev_ * are written to files in the directory /usr/sap/<SID>/<instance

      directory>/work of the SAP application server that generated the trace.

      2.In accordance to these letters lines that contain error information begin with *** ERROR =>. Lines for which system log entries are written start with *** LOG . An "error line" contains the name of the calling function, the operation that failed, the error number from the host system (if a system call is involved), and the name of and line in the C module that failed. Use this information to search relevant SAP note or further analysis etc.

      3.Each line in the trace files starts with the component abbreviation. This is the letter that identifies the trace component that you want trace, decide according to problems/requirements of your system, refer: http://help.sap.com/saphelp_nw70/helpdata/EN/be/470dc21ca4447b828597f614aaaec1/content.htm

      4.Setting the trace parameter in the instance profile of a particular server activates developer traces only in that server. Setting the parameter in the default profile would activate traces in all servers (excepting those whose instance profiles specify a different parameter value). so it's matter of system configuration to be done by administrator, for details refer: http://help.sap.com/saphelp_nw70/helpdata/EN/be/3723f3d41b41a9bc2ec54d03618948/content.htm

    Work procesess belongs to the application servers. There is possibility that number of work processes on each application server and CI may be different. If you open the trace files and profiles you will see all the details.

    Hi Ravi,

    To get the dev_w* trace files of each Application servers from ST11, just double click on the required application server from SM51. Then it will show SM50 screen of the corresponding Application server selected. From there just enter the tcode /nst11 and it will display you the trace files of the selected Application server.

    Each application servers may be in different host and hence will have seperate filesystem each to store the work process trace files of the application server seperately. Hope this clarifies your query,

    Regards,

    Karthick.
