How to enable Internet Sales to write logsin a separate log file
in Release 5.0
Purpose
The purpose of this document is to show you how to enable the
ISA application to write logs in aseperate log file and not in the
default trace.
Prerequisites
This guide will take you through the following prerequisites,
step-by-step. Once these are done,single session logging is
activated and can be carried out as described in the last chapter
Startingsingle session logging. Should you have any problems,
ensure that all of the prerequisites havebeen carried out exactly
as described.
Prerequisites? Add com.sap.isa to the key
SingleTraceFile_UnrestrictedLocations? Create the log formatter?
Enter a log file destination
IMPORTANT
After making the required settings, note that you still have to
start the session log in the InternetSales application by setting
the request parameter appinfo to true, or by using the Single
SessionTrace link on the start.jsp.
Also, the destination is deleted after restarting the J2EE
Engine. If you want to run the trace againyou have to repeat the
steps described in the last chapter Starting single session
logging.

1. Log in to your J2EE engine with the Visual Administrator.2.
Go to Server => Kernel => LogManager.3. The
SingleTraceFile_UnrestrictedLocations must contain the required
location
"com.sap.isa". If you need to maintain more then one Location
please separate them with";".
4. Save your settings.

set the following
in the resulting pop-up:

Starting single session logging
1. Select the Runtime => Locations tabs.2. Choose the
advanced mode.3. In Log Controllers, go to Root Location => com
=> sap => isa.4. Select Add, enter the destination, and set
the severity level to Debug.
5. Save and choose Apply to all server nodes.
Now ISA writes its own log file and you are finished from the
J2EE side. Please note that Step 2to 4 does not require a re-start
of the Cluster node. If not, set ForceSingleTraceFile to NO in
thelog manager setting of the Visual Administrator.
