the J2EE resource (the ECI resource adapter). Using Server or Role would
cause either the Server’s user ID or EJB role security to be used.
► ThreadID
This parameter is set on the EJB deployment descriptor in the +ThreadID tab
by selecting Set OS Thread Identity to RunAS Identity for the methods in
the home and remote interface. The default is for the value not to be set. It
controls the operating system identity on the thread of execution and allows
the security context of the thread to be switched to that of the caller itself. If
set for a J2EE/EJB application using the ECI resource adapter, this will
change the link user ID for the EXCI request to be the flowed user ID rather
than the user ID of the J2EE Server.
► Res-Auth
This parameter controls whether the container or application component will
determine the user ID. This defaults to container and this is what we used,
since this will honor the settings for ThreadID and RunAS. If Res-Auth is set
to application then the user ID and password are taken from the values
specified in the getConnection() method.
10.4 Problem determination
In this section, we document useful information we learned while configuring this
scenario and further information on problem determination and tracing.
10.4.1 Tips and utilities
In this section, you will find commands and utilities to use in debugging problems
with your configuration. You will also find some additional information about
topics discussed in this chapter.
WebSphere logs
WebSphere Application Server uses the MVS Logger to store its log data, and
therefore for setup you need to define policies to the MVS Logger for this
purpose. In order to access and read this log information, you need to have
access to a sample CLIST called BBORBLOG, which is supplied on the
SBBOEXEC data set, which can be run using the following command:
EXEC 'BBO66.SBBOEXEC(BBORBLOG)' 'WAS.SC66.ERROR.LOG'
Where WAS.SC66.ERROR.LOG is the name of the MVS Logger logstream definition
containing the log data. A sample of the type of information you might find when
you enter this command is shown in Example 10-7.
