Troubleshoot: wsadmin General Errors

How do I enable runtime trace for server processing using scripting?

ts = AdminControl.completeObjectName('type=TraceService,process=dmgr,*') AdminControl.setAttributes(ts, '[[traceSpecification *=info:com.ibm.ws.management.*=all:com.ibm.websphere.management.*=all] [traceRuntimeConfig ] ]')

server = AdminConfig.getid("/Cell:mycell/Node:mynode/Server:myserver/" ) ts = AdminConfig.list("TraceService", server ) AdminConfig.modify(ts, [["startupTraceSpecification", "*=info:com.ibm.ws.management.*=all:com.ibm.websphere.management.*=all"]] ) AdminConfig.modify(ts, [["enable", "true"]] ) trclog = AdminConfig.list("TraceLog", ts ) AdminConfig.modify(trclog, [["maxNumberOfBackupFiles", 20], ["rolloverSize", 200]] ) AdminConfig.save( )

When you get this error when running a wsadmin script, there are several possible issues that you should check for:
• The server to which wsadmin is attempting to connect is not running.
• The port and hostname that wsadmin is attempting to use is incorrect.
• If wsadmin is not supposed to connect to a running server, then it needs to start with option:

-conntype NONE

You may see an error like this when you attempt to run a Jython script:



WASX7022E: Problem running command "import sys" -- exception information: com.ibm.bsf.BSFException: unable to load language: jython; org.python.core.PyObject WASX7017E: Exception received while running file "[install_root]/bin/securityProcs.py"

If you get an error like the one shown, make sure following file exists:

[install_root]/optionalLibraries/jython/jython.jar

If your wsadmin script fails with this error, try increasing the SOAP request timeout by changing the value for the com.ibm.SOAP.requestTimeout custom property in [install_root]/profiles/profile_name/properties/soap.client.props. The default value for com.ibm.SOAP.requestTimeout is 180 seconds.

If you get this error when trying to use command from scriptLibraries, do the following:

1. Check files under [install_root]/scriptLibraries and compare them with the working environment.
2. Copy the Python files from the working environment if they are missing.

Problem: Your wsadmin script hangs and hung thread shows the following stack:



at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:155) at com.ibm.jsse2.a.a(a.java:19) ... at com.ibm.ws.management.connector.soap.SOAPConnectorClient.queryNames (SOAPConnectorClient.java:511)

Recommendation:
In a large cell environment, if a wsadmin script calls AdminControl.queryNames() with a too broad scope, it will cause delays because the queryNames() call will be sent out to all the JVMs. This can take a long time and cause issues.

For instance, instead of following command:

nodeSyncObjects = AdminControl.queryNames("type=NodeSync,*")


Use following query string, so that queryNames call will only be sent to nodeagent processes which saves time:

nodeSyncObjects = AdminControl.queryNames("type=NodeSync,process=nodeagent")
