Troubleshooting

Problem

When trying to add a 3rd party appender (e.g. biz.minaret.log4j.DateFileAppender) in TDI environment, below error is thrown at server startup: "ERROR Could not instantiate appender named "Default".

Symptom

TDI Server startup shows following messages:

Cause

TDI initializes Log4j before we have had a change to set up loader which looks through the jars directory, and hence we get exception "java.lang.ClassNotFoundException"

Environment

Windows, TDI 7.0, TDI 7.1

Resolving The Problem

1. Ensure that 3rd party jar file is present at TDI_HOME_DIR%\jars.
2. Modify "ibmdisrv.bat" to include the jar (e.g. "datedFileAppender-1.0.2.jar") in classpath like below:

"%TDI_JAVA_PROGRAM%" -classpath "%TDI_HOME_DIR%\jars/log4j-datedFileAppender-1.0.2.jar;%TDI_HOME_DIR%\IDILoader.jar" %ENV_VARIABLES% com.ibm.di.loader.IDILoader com.ibm.di.server.RS %*
3. Restart TDI.

In case we apply latest fix pack, changes made to "ibmdisrv.bat" will only be preserved, if respective fix pack does not have any modifications in "ibmdisrv.bat".
