ORA-30683: failure establishing connection to debugger
Cause: An error was indicated when trying to establish a connection to a debugger. Usually a TNS error will display along with this message to further explain the problem, although this TNS error will likely be hidden if you choose to trap the error.
Action: Correct the indicated parameter value and try again.
ORA-30685: package version is not compatible with Oracle version
Cause: The installed version of the package from which this error is raised is not compatible with this release of Oracle.
Action: Install a compatible version of the package’s spec and body.
ORA-30686: no dispatcher accepted TCP/IP connection request
Cause: A connection had to be routed through a local socket rather than a dispatcher. When this occurs, shared servers are less beneficial because the session that owns the socket cannot relinquish the process until the socket is closed. The most likely cause is that no dispatcher is configured for protocol=tcp.
Action: To improve the scalability of your configuration, configure a dispatcher for protocol=tcp. To route these particular connections through a particular set of dispatchers, you can specify presentation=kgas. However, if you haven’t done so, any protocol=tcp dispatcher will be used.
ORA-30687: session terminated by debugger
Cause: Your program’s execution has been stopped by the debugger. This can occur because of an explicit request to do so sent by the debugger, or because the debugger disconnected without first telling Oracle to let your program continue to run after the disconnection. To stop your program completely, Oracle needs to fully terminate the process.
Action: This is in response to a debugger request; it is not an error. No action required.
ORA-30688: maximum program calling depth exceeded
Cause: Your program contains a set of calls that are too deep to be handled. Only transitions between the different execution engines (SQL, PL/SQL, and Java) count in reaching this limit; calls within the same engine don’t count.
Action: Restructure your program so as to not call so deeply. Perhaps some recursion can be replaced with iteration.
ORA-30689: improper value for ORA_DEBUG_JDWP
Cause: An improper value was used for ORA_DEBUG_JDWP when trying to establish a connection to a debugger. The value either did not conform to the format of ORA_DEBUG_JDWP or was too long.
Action: Correct the value for ORA_DEBUG_JDWP and try again.
ORA-30690: timeout occurred while registering a TCP/IP connection for data traffic detection
Cause: A timeout occurred while registering a TCP/IP connection for data traffic detection.
Action: Retry the operation later.
ORA-30691: failed to allocate system resources while registering a TCP/IP connection for data traffic detection
Cause: System resources ran out while registering a TCP/IP connection for data traffic detection.
Action: Retry the operation later.
ORA-30695: JDWP message format problem
Cause: A message passed from one software subcomponent to another using the JDWP protocol appears invalidly formatted.
Action: This is an internal error. Contact ORACLE Support Services.
ORA-30725: JDWP-based debugging is not yet available
Cause: This feature is not yet available for use.
Action: Please wait for a future release.
ORA-30726: cannot specify referenced column list here
Cause: An attempt was made to specify a referenced column list for a referential constraint involving a REF column.
Action: Remove the referenced column list specification.
