impossible to run JDBC Connector with the following error:
ERROR 20060704 18.02.10.65 procengine(procengine(hierchmsgenv))
[JDB - 18003]: Unable to find class com/axway/xib/Connector. JDBC connector is not properly installed

There are several different potential causes

1. HME / PE is not dedicated to the JDBC connector
create a new dedicated HME and a new JDBC_procengine.
In the new HME, only the JDBC_procengine was selected as task.
In the integration task, for the sequential activity that performs the SQL map broker, the new HME was selected.

2. Incorrect path
On Unix, modify the PATH as follow :
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin/classic:$JAVA_HOME/jre/bin:$ORACLE_HOME/bin:$LIBPATH:$SHLIB_PATH:$PATH

3. the file $CORE_ROOT/java/lib/axway/JDB_Archive.jar has been manually removed
Retrieve the jar file from another installation (or ask support) and put it in $CORE_ROOT/java/lib/axway and restart Integrator
