Connection Exceptions
 
Exception Code
Description
Notes
ConnectionException001
Unable to initialize Connection Pool
Cannot initialize a connection pool session. The maximum number of sessions has been reached, or the QAD Enterprise Applications databases are not up. There may also be a problem with the log-in script or a step omitted. Test this by following the log-in script from the Connection Pool setup parameters and ensuring all steps are correct.
Another possible cause is that the startup script for launching the QAD Enterprise Applications session (invoked by the Connection Manager) may have been configured to run in normal mode instead of MFGWrapper mode. (See Starting QGen for more on the MFGWrapper mode.) Review the startup script and update if incorrect, then restart the Connection Pool.
ConnectionException002
Unable to get a working session using unique IDs (session ID and process sequence ID)
Unable to get a working session using unique IDs.
ConnectionException003
Failure to initialize the Connection Pool Manager
The Connection Pool Manager cannot initialize. One responsibility of the Connection Pool Manager is to open XML configuration files. This error can occur if there is an invalid configuration file. To see a list of configuration files look at config-files.xml.
ConnectionException004
Unable to get an idle session
A client requested a new program to be run and an idle session cannot be retrieved from the connection pool. Verify that the connection pool has not exceeded the maximum number of connections. It is also possible that the Connection Pool Manager was initializing new sessions that were not yet available.
ConnectionException005
Unable to get session because pool has been shut down
A user attempted to create a new session or make a request on an existing one after the Connection Pool Manager was shut down. In this case, all connections are invalid and the Connection Pool Manager must be restarted.
ConnectionException006
User has reached max sessions allowed
A user has requested to run another QDoc; however, this user has exceeded the maximum number of allowed connections.
ConnectionException007
Extracting a value from the configuration file failed
Invalid value encountered during load of connectionManagerConfig.xm. Review all numeric values in the file.
ConnectionException008
Unable to locate the Connection Pool Manager configuration file
This file should be located in webapps/< QXI webapp >/WEB-INF/config. If it is not there, then a default version of the file can be copied and configured. This is located in webapps/< QXI webapp >/WEB-INF/config/defaults
ConnectionException009
Telnet connection not available
The telnet server for the specified receiver is unavailable.
ConnectionException010
Host is unavailable or incorrect
View the connection pool details for this receiver and validate the host is correct and available.
ConnectionException011
Telnet connection is refused
The connection to the host was refused. Manually launch a telnet connection from the QXtend machine to the host machine to isolate the problem.
ConnectionException012
QAD Enterprise Applications server is unreachable
The connection to the host is successful but the launch of an QAD Enterprise Applications session is not. Manually launch a telnet connection from the QXtend machine to the host machine and run the QXtend startup script to isolate the problem.
