For ease of use in viewing an SAP Note, right click on the Note link and select Open in new window or Open in new tab.
- Contains logs and traces from NetWeaver engine and Java EE applications - including SAP ME logs (see SAP Note 1266339 how to enable and view SAP ME traces on Netweaver).
- Will contain stack traces if an error occurs in the system. The stack traces help pinpoint the root cause of the issue.
- You should always check this log first when any system issue is reported. You can find defaulttrace files under /usr/sap/<SID>/<Instance>/j2ee/cluster/<server>/log path. Select the image to expand it.
Some tips for getting useful information include:
- In instances where there are lots of entries during a short period of time it is usually easier to obtain the stack trace manually from the raw text file than through the Log Viewer GUI.
- You can collect SQL trace for only one specific user as per SAP Note 2270991
- If there are multiple stack traces with the same time stamp, than the most useful one is usually the first one.
- When submitting a stack trace to support be sure to include the entire contents of the stack trace.
- Contains startup parameters for the server node.
- Contains verbose garbage collection output.
- You should always check this file when a memory issue is suspected. You can find dev_serverX files under /usr/sap/<SID>/<Instance>/work path. Select the image to expand it.
- Contains startup parameters for ICM.
- Contains information about ICM runtime activity.
- You should always check this file when connectivity issues to the application server are suspected. You can find dev_icmX files under /usr/sap/<SID>/<Instance>/work path. Select the image to expand it.
- Contains HTTP response code for all HTTP responses from the server node.
- Contains IP address of HTTP client.
- Contains URL of HTTP request.
- You should check this file when troubleshooting HTTP errors.
- You should check this file if you suspect a spike in HTTP request activity. You can find responses.trc files under /usr/sap/<SID>/<Instance>/j2ee/cluster/<server>/log/system/httpaccess path. Select the image to expand it.
