How to read J2EE logs?

[Former Member]

Hi,

The portal went down for an hour and unable to investigate the cause.

However, there is an option of going through .log file.

1. Is there any way to upload this log file and get the analysis?

2. If not, any other solution to identify the cause of the outage?

Raise a OSS with SAP ad they can provide you some ftp links where you can upload your log files.

If you can access SAP Netweaver Adminidtrator NWA you have the option to view all log files (it highlights the error/warnings) , default trace files, dev_jrrfc.log etc and it also gives you the option to download them all (or based on some filter) in one shot. (staring Netweaver 7.0)

NWA :

http://hostname.dnsname:5<instance num>00/nwa

login as Administrator user (ex J2EE_ADMIN) goto the "Monitoring" Section --> select the type of logs you need from Drop Down --> Apply data source Filter ( if you want for specific Server node or Dispatcher) --> apply filter and you get all the needed files.

At the top you a download button, which lets you download everything.

Hello,

You can use the SAP java log viewer. It's working with stopped application too.

The path is \usr\sap\<SAPSID>\JC<xx>\j2ee\admin\logviewer-standalone

But, SAP java log viewer relevant only up to systems 7.0

For systems 7.1, you should use the SAP Host Control Agent.

Hi,

If you have access to the OS level. host, goto folder usr\sap\<SID>\JC<sysnr>\work and refer the latest logs. ex: dev_dispatcher, dev_server0 logs, This will help you identify the cause of the issue.
