Stat 6.2 - Install Notes

Resolving port and firewall conflicts

If the Stat® Central Agent will not run when started, the port assigned to it may already in use by a different program or there are firewalls that need to have ports opened for the Stat Central Agent to communicate with the database or with the Stat Client.

Typical port and firewall conflicts include:

If you have port conflicts, the server will display one or more error messages, such as:

The Stat Central Agent utilizes a set of ports that are already defined.

These values are defined for a default port offset of zero which is set in a variable called jboss.socket.binding.port-offset in standalone.conf.bat or standalone.conf file. If there is a conflict situation or a second or third agent is necessary, you may change the jboss.socket.binding.port-offset in standalone.conf.bat or standalone.conf file. The value for offset is added to all the default values.

For example:

NOTE: Be aware of the following: • Stat invokes the DNS server to resolve the fully qualified server name when communicating between the client and the central agent. When server hostname is not registered on the DNS server, use etc/hosts file to map hostname and its IP address. • HTTPS connector socket and Management socket — These ports are only necessary if the Stat Central Agent is configured to support HTTPS. See Configure Web Client to Use HTTPS.

When other applications are using the same port as the Stat Central Agent, you need to change the port offset in your standalone.conf.bat or standalone.conf file.

The http port is the only port that needs to be opened on existing firewalls.

Other ports used by the Stat Central Agent include the following (the actual port numbers will vary according to your site specifications):

The Stat Client will need the same ports opened if there is a firewall between the client and any of the above items.

If there is a natted firewall between the Stat Central Agent and the Stat Oracle Agents, the following options must be configured in the stat.conf file for the Stat Oracle Agents. Older versions of Stat always required the fields to be filled in, but since 5.7.0, the Stat Oracle Agents query the Stat Central Agent for the secure Stat database information. You need only change the stat.db.server: value and indicate the natted ip address. For this scenario, they are not optional.

Stopping the Stat Central Agent

To stop the Stat Central Agent on either a Windows or a Unix platform, do one of the following:

You can also create a desktop shortcut which sends the appropriate command-line shut down argument to the Stat Central Agent.

If you have modified your port offset from the default value of zero due to conflicts with other systems, etc., then you must supply the modified port information to the shutdown command so that it can find the server to shut it down.

For example, if you modified the port offset to one, you need to edit %STAT_HOME%\app\bin\shutdown.bat and modify it as below:

For Unix installations, you need to edit $STAT_HOME/app/bin/shutdown.sh and modify it as below.

Also, if you running more than one Stat Central Agent on the same host machine, you must specify the port offset. In this case, you must also specify the port number when executing the shutdown command. The port numbers for a port offset of one is 9991 and for a port offset of 100 is 9990+100=10090. Again, these numbers may be modified if they conflict with other applications.

Configuring the Stat Central Agent as a Windows service

If you previously used Wrapper.conf and other associated files to run the Stat® Central Agent functionality of the Stat Central Agent as a Windows® service, you must replace those files with the wrapper that is provided with the Stat Central Agent using the service.bat command located in the <STAT_HOME>/app/bin/service folder.

NOTE: You may use the actual hostname instead of localhost above. Also note that port 9990 is used when your default post-offset is zero. If you have changed the port-offset, you need to use the corresponding management socket binding port.

NOTE: The log files created in the <STAT_HOME>\app\standalone\log directory by service.bat are persistent. You should monitor the size of this file while running as a service.

NOTE: If you experience issues when stopping the service, you need to edit <STAT_HOME>\app\bin\jboss-cli.bat and uncomment and set the JAVA_HOME location.

Installing DB2 Support for the Stat Central Agent

The requirements have changed since 5.6.3. The DB2® Client connect does not need to be installed on the Stat® Central Agent machine, however the agent does need the jdbc drivers provided in DB2 connect.

The Stat Central Agent uses the IBM® JDBC type 4 driver. The required files can be found in C:\Program Files\IBM\SQLLIB\java of the DB2 client installation. Note that Stat requires a 32 bit version of these files.

NOTE: When you modify an .xml file, be sure that there is only one copy of it in the directory when you are finished. Do not rename the old copy and leave it in that directory.
