How to enable LeakHunter in Wily Introscope

[Former Member]

Hello all,

I'm running an NW04 SPS18 with Wily Introscope 7.1. I experience java.lang.OutOfMemoryError quit often, so I want to set up Introscope's LeakHunter. I found this Document https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d281836d-0b01-0010-bfa9-ba473646...

which was quite helpful. Nevertheless I can't find the file "leakhunter.pbd" which is mentioned in this doc anywhere. Has anyone successfully set up the LeakHunter already?

kind regards,

Markus

Hi

I happened to see your message when trying to setup the leakhunter.

I finally got it working - in case this helps I attach the method I followed.

1) I used agent profile “sap_IntroscopeAgent_ipc.profile”.

To enable LeakHunter, set the following parameter:

introscope.agent.leakhunter.enable=true

2) Find which directives file (.pbd) or directives list file (.pbl) is specified – this is seen in parameter:

introscope.autoprobe.directivesFile=sap_ipc_typical.pbl

3) Edit this file, ensuring that the line “leakhunter.pbd” must be uncommented:

1. Introscope standard pbds

java2.pbd

j2ee.pbd

jvm.pbd

sqlagent.pbd

struts.pbd

errors.pbd

1. disabled by default leakhunter.pbd

leakhunter.pbd

Restart the J2EE cluster and the leakhunter should be working

regards

Ratna
