The eG Installation Guide - eG Innovations

Troubleshooting
This error message appears when there is a JDBC driver mismatch - i.e., when the JDBC driver
bundled with the eG manager is not compatible with the JDBC driver of the Oracle database that is
in use in the monitored environment.
To resolve this issue, do the following:
Take a backup of the JDBC driver that is bundled with the eG manager, from the
\lib folder.
Download the latest release of the JDBC driver that is compatible with the version of the
Oracle database server that is in use in your environment, using the link:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
Rename the downloaded driver as classes12.zip in case of Windows, or as classes11.zip in case
of the Unix manager.
Copy the renamed file to the \lib directory (in case of the Windows manager),
or the /opt/egurkha/lib directory in case of the Unix manager.
Restart the eG manager.
8.4 Starting the eG Manager
The eG installation went through fine, but I am not able to start the manager. What could be wrong?
1. Check to make sure that you have a valid license. The license must be stored in a file named
/bin/license.
2. Run the command “viewCert license” from the “/bin to make sure that your
license has not expired.
3. Make sure that the eG user has permissions to read and write from all the eG directories.
4. When installing the eG manager, you will be asked to enter an IP address or hostname for the
host on which the manager is being installed. Make sure that this IP address or hostname
(what you specified during the installation) is accessible over the network. E.g., if you
specified a hostname and the DNS service is not configured to resolve this hostname, the eG
manager will not start.
5. Please make sure that you are logged in as the eG user. Other users will not be allowed to
start the eG manager.
6. If an eG manager was previously installed, ensure that this manager was stopped and
uninstalled before the new manager is installed and started.
The eG manager used to work. Suddenly, it has stopped working. What could be wrong?
1. First, check for expiry of the eG license. Run the command “viewCert license” from the “/bin to make sure that your license has not expired. If the license has expired, the
eG manager will not start.
2. This problem can also occur if you have uninstalled the Java environment that you had
specified when installing the eG manager. Even an upgrade of the java environment or
changing the java installation directories can cause problems. You will need to edit the /bin/start_manager script on Unix to restart the manager. On Windows, reinstall Java in
the same location.
3. If the IP address or hostname of the database server has changed, the eG manager will not
start properly. Reconfigure the eG database setting by editing the file
/manager/config/eg_db.ini.
