LOG FILES

Former Member — Fri, 18 May 2007 00:57:56 GMT

Hi there,

I wanna to know where can i find the log file which executes the codes that we have uploaded into the EP as PAR file.

I am now doing portal application and currently i am doing some debugging myself to my database connection codes to test out whether it works so i need a log file in the server to see where the codes have gone wrong.

Thanks Loads

Log files will be stored in

<SAP WebAS install dir > /

JC<Instance no> / j2ee/cluster/server0/log/defaultTrace.trc

(usr/sap/PRT/JC10/j2ee/cluster/server0/log/defaultTrace.trc)

if you use System.err.println(" sdfsdf"); It will be recorded in the log file file

otherwise you can user logger also . SAP has logging.jar to store logs

Hi,

By default, the path will be <Drive:>\usr\sap\J2E\JC00\j2ee\cluster\server0\log

Check for the defaultTrace updated recently.

U can also view this file from visual admin.

Hi Quatre ,

SAP has its own component for loggig ,messaging,notification and all.You can find the Log files as

J2ee :- The physical location of the log file are:

<Your_server_drive>:usrsap<SID>(3 Characters)<SYS>(4 character)j2eeclusterserver0log

Portal :-<Drive>usrsap<SAP_System ID>JC<J2EE Engine Instance>j2eeclusterserver<n>appssap.comirjservlet_jspirj ootWEB-INFportallogs

In the Portal, go to Java Development > Portal LogViewer

you need to have the Java Developer role to be able to view this

Assign these roles for that

SAP_JAVA_NWADMIN_CENTRAL

SAP_JAVA_NWADMIN_CENTRAL_READONLY

SAP_JAVA_NWADMIN_LOCAL

SAP_JAVA_NWADMIN_LOCAL_READONLY

SAP_JAVA_NWMOBILE_ADMIN_READONLY

SAP_JAVA_NWMOBILE_ADMIN_SUPER

SAP_JAVA_SUPPORT

Refer to this for more details

IF EP 7

you can even loggin to http://<hostname>:port/nwa

A new utility provide by SAP where you can monitor the server stats and loads of things .Infact the Logs can also be seen.

System Managemnt~~>Configuration~~>Log configuration,

System Managemnt~~>Administration~~>Log and trace.

thanx

Hello sir ,

try checking over here

:\usr\sap\<SID>\JC01\j2ee\cluster\server0\log

or if still does nt work try to write the log inside a file which can be set inside the code wriiten by you and call the standard logging api of SAP.

Thanx
