OpenLink's Request Brokers are listening services. OpenLink's
4.x and newer Brokers listen on the TCP port that is passed to the
Listen parameter. The Listen parameter appears in the
Protocol TCP section of the Session Rules Book.
OpenLink's 3.x and 1.x Brokers listen on PortLow. PortLow appears
in the Protocol TCP section of the Session Rules
Book. OpenLink's Request Brokers also use UDP port 60001 to
broadcast license information.
Use the following guidelines to troubleshoot Broker startup
- Ensure that OpenLink's Request Broker is installed.
- Ensure that Unix Request Brokers are executable.
- Run oplrqb -? from the /bin sub-directory of the OpenLink
server components installation. Insure that the Request Broker
returns version and usage information. Troubleshoot errors, as
- Run uname -a on Unix servers. Compare the Broker's platform of
compilation with the platform identified with uname -a. Insure that
the platform of compilation is compatible with the platform
returned by uname -a. Install more suitable builds, as
- Open the Session Rules Book and identify the Broker listening
- Run netstat -an, or an equivalent network utility, to check for
existing activity on the Broker's listening port. Reassign a free
port, or wait for previous listeners to be cleared (up to 2
minutes) as required.
- Obtain operating system patch information. Some patches may
interfere with the Broker's ability to run.
