Recipe

1. Review the Java in Containers recipes
2. Execute /work/configure.sh as the last step in your Containerfile
3. Review the WAS traditional recipes
4. Review the Java recipe
5. Review the Operating System Recipes

Log Analysis Dashboards

WAS traditional provides a Kibana dashboard example.

Build Example

1. Create Containerfile:

   FROM icr.io/appcafe/websphere-traditional
   COPY --chown=was:root twasdiag.ear /work/app/
   COPY --chown=was:root trace.jy /work/config/
   RUN /work/configure.sh

   1. twasdiag.ear taken from https://github.com/IBM/twasdiag/releases/latest
   2. trace.jy:

      AdminControl.setAttribute(AdminControl.queryNames('type=HPELLogDataService,process=server1,*'), "purgeMaxSize", "1024")

2. Build:

   podman build --platform linux/amd64 -t twas .

3. Run:

   podman run --rm --platform linux/amd64 -p 9043:9043 -p 9443:9443 twas

4. Access:
   1. Administrative Console: https://localhost:9043/ibm/console
   2. twasdiag: https://localhost:9443/twasdiag

Run Examples

With a custom password

Create a file in the current directory named PASSWORD with an administrative password as its contents. For example:

wsadmin

Then run:

podman run --rm --platform linux/amd64 -p 9043:9043 -p 9443:9443 -v $(pwd)/PASSWORD:/tmp/PASSWORD -e ENABLE_BASIC_LOGGING=true icr.io/appcafe/websphere-traditional

With an auto-generated password

With an auto-generated password:

podman run --rm --platform linux/amd64 -p 9043:9043 -p 9443:9443 -e ENABLE_BASIC_LOGGING=true icr.io/appcafe/websphere-traditional

After you see "open for e-business", access the administrative console with the user name wsadmin and the password from the PASSWORD file at https://localhost:9043/ibm/console/login.do?action=secure

To find the password, first find the container; for example:

$ podman ps
CONTAINER ID  IMAGE                                        COMMAND               CREATED         STATUS         PORTS                                           NAMES
3c7a57912f96  icr.io/appcafe/websphere-traditional:latest  env JVM_EXTRA_CMD...  47 seconds ago  Up 47 seconds  0.0.0.0:9043->9043/tcp, 0.0.0.0:9443->9443/tcp  vigilant_knuth

Then cat the file in the container; for example:

podman exec -it 3c7a57912f96 cat /tmp/PASSWORD

Common Actions

Dynamically Set Diagnostic Trace

1. Exec into the container
2. Start wsadmin:

   /opt/IBM/WebSphere/AppServer/bin/wsadmin.sh -lang jython

3. Set trace:

   AdminControl.invoke(AdminControl.completeObjectName("type=TraceService,process=server1,*"), "setTraceSpecification", "*=info:com.ibm.ws.rsadapter.jdbc.WSJdbcCallableStatement=all:com.ibm.ws.rsadapter.jdbc.WSJdbcPreparedStatement=all:com.ibm.ws.rsadapter.jdbc.WSJdbcStatement=all")

4. Exit wsadmin:

   exit

wsadmin examples

• Print static HPEL configuration:

  print AdminConfig.showall(AdminConfig.list("HPELLog", AdminConfig.getid("/Cell:DefaultCell01/Node:DefaultNode01/Server:server1/HighPerformanceExtensibleLogging:/")))

• Print dynamic HPEL configuration:

  print AdminControl.getAttribute(AdminControl.queryNames('type=HPELLogDataService,process=server1,*'), "purgeMaxSize")
