LOG FILES

[Former Member]

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

Hi

Refer to this thread

Also the Logging framework

http://help.sap.com/saphelp_nw04/helpdata/en/3a/63e540aa827e7fe10000000a1550b0/frameset.htm

http://help.sap.com/saphelp_nw04/helpdata/en/fa/44d94016828431e10000000a1550b0/frameset.htm

See Check for the trace file they have all your application logs .I dont think so for so much of thing we will have to go into so much complexties.Check the latest trace file.

Hi,

you can check you log files in by following this steps

login to the portal with super admin

say

http://<host name>:port/irj/portal

now after logging in remove

irj/portal from the url and type

nwa

now it will open one new screen here you double click on

monitoring

and it will open new screen here you press on

logs and traces

and it will navigate you into another window ther in drop down list select

default traces.

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

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

Or

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,

or

System Managemnt>Administration>Log and trace.

thanx

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

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
