Oracle 11g Error Codes and Solution Suggestions from ORA-04900 to ORA-06100

ORA-04930: open sequence number failed or initial state is valid
Cause: Either Shared Sequence Number OS component was not installed properly, or an MC hardware failure may have occurred or a previous instance was not shut down properly.
Action: Verify that there are no background or foreground Oracle processes from a previous instance on this node using the OS command ps -ef|grep <instance_name>. Verify that there are no shared memory segments belonging to the user which owns the Oracle installation by isuing the ipcs -b OS command. If there are shared memory segments or processes still on the system, use svrmgrl to shutdown the instance with the abort option. If the instance is not up, verify that the cluster software and/or the hardware is installed and working. Log in as superuser and issue the cnxshow command. Are all of the nodes in the cluster listed? Are they members of the cluster? Is the communications between nodes okay? If the answer to any of these questions is false, contact Digital’s customer support organization.
ORA-04931: unable to set initial sequence number value
Cause: A call to the SSN failed to set the sequence number to its initial value, possibly caused by an MC hardware problem.
Action: Verify that the MC hardware is functioning properly. If it is not, contact Digital’s customer support organization. If it is, contact Oracle support.
ORA-04932: increment or adjust of sequence number failed
Cause: A call to the SSN failed to increment the sequence number.
Action: Verify that the MC hardware is functioning properly. If it is not, contact Digital’s customer support organization. If it is, contact Oracle support.
ORA-04933: initial service identifier is non-zero
Cause: A valid service identifier existed before the sequence number service was opened.
Action: Verify that the instance is completely shut down.
ORA-04934: unable to obtain the current sequence number
Cause: A call to the SSN failed to return its current value. Either there are many errors occurring on the MC hardware, or the sequence number has become invalid and cannot be validated.
Action: Verify that the MC hardware is functioning properly. If it is, contact Oracle Support.
ORA-04935: unable to get/convert SCN recovery lock
Cause: A process has timed out trying to get or convert the SCN recovery lock. Another process probably has the lock in EX or SHR mode, but is not releasing it.
Action: Contact Oracle Support.

ORA-04940: unsupported optimization of Oracle binary, check alert log for more info
Cause: ORACLE binary has been optimized with unsupported options or a required option has not been used.
Action: Check the documentation for a list of supported and required flags for the optimizing utility that you used to optimize ORACLE. Shutdown the instance, optimize ORACLE again with supported combination of options and restart the instance.
ORA-04941: required operating system patch needs to be applied
Cause: The operating system could not return the start time of a process.
Action: Check that the operating system kernel has been patched to return process start time. Apply the required operating system patch and restart the instance.
ORA-06000: NETASY: port open failure
Cause: Autologin unable to open port
Action: Check log file for OS-specific error code
ORA-06001: NETASY: port set-up failure
Cause: Autologin unable to change port attributes
Action: Check log file for OS-specific error code
ORA-06002: NETASY: port read failure
Cause: Autologin unable to read from port
Action: Check log file for OS-specific error code
ORA-06003: NETASY: port write failure
Cause: Autologin unable to write to port
Action: Check log file for OS-specific error code
ORA-06004: NETASY: dialogue file open failure
Cause: Autologin unable to open dialogue file
Action: Check connect string for accuracy/typos
ORA-06005: NETASY: dialogue file read failure
Cause: Autologin unable to read dialogue file
Action: Check log file for OS-specific error code
ORA-06006: NETASY: dialogue execute failure
Cause: Expected response never received
Action: None
ORA-06007: NETASY: bad dialogue format
Cause: Dialogue file contains syntax error
Action: Correct the dialogue file
ORA-06009: NETASY: dialogue filename too long
Cause: Full file spec for dialogue file exceeds 64 bytes
Action: Amend connect string accordingly
ORA-06010: NETASY: dialogue file too long
Cause: Dialogue file exceeds 768 bytes in length
Action: Simplify dialogue (e.g. remove comments, redundant white space), or split into two and link with “more” command
ORA-06011: NETASY: dialogue too long
Cause: One of two:
1. Dialogue contains more than 24 exchange blocks
2. Dialogue send string exceeds 84 bytes in length
Action: Simplify dialogue or split into two and link with “more” command
ORA-06017: NETASY: message receive failure
Cause: Async driver gets I/O error while doing network read operation
Action: Check log file for OS-specific error code and contact your customer support representative.
ORA-06018: NETASY: message send failure
Cause: Async driver gets I/O error while doing network write operation
Action: Check log file for OS-specific error code and contact your customer support representative.
ORA-06019: NETASY: invalid login (connect) string
Cause: Syntax error in login string.
Action: Resubmit with correct string.
ORA-06020: NETASY: initialisation failure

ORA-06022: NETASY: channel open failure
Cause: no free channel [should never happen]
Action: Contact your customer support representative.
ORA-06023: NETASY: port open failure
Cause: Async driver unable to open port
Action: Check log file for OS-specific error code
ORA-06024: NETASY: VTM error
Cause: Virtual Terminal Manager unable to read/write to port
Action: Check log file for OS-specific error code
ORA-06025: NETASY: Configuration error
Cause: Async driver genned for server-only, but client service requested
Action: Contact your customer support representative.
ORA-06026: NETASY: port close failure
Cause: Async driver unable to close port
Action: Check log file for OS-specific error code
ORA-06027: NETASY: channel close failure

Cause: Node name specified in host string is unknown (probably misspelled)
Action: Retry with correct node name
ORA-06031: NETDNT: connect failed, unrecognized object name
Cause: Host string contains reference to object (which doesn’t exist): @d:<node>-<obj> => object is ORDN<obj>; when <node> is VMS, the object is ORDN<obj>.COM when <node> is UNIX, the object is ORDN<obj> @d:<node>::”task=<obj>” => object is <obj>; when <node> is VMS, the object is <obj>.COM when <node> is UNIX, the object is <obj>
Action: Retry with correct object name or create the required object on host node
ORA-06032: NETDNT: connect failed, access control data rejected
Cause: Host string contains invalid username/password

Cause: Connection with partner was made but was rejected.
Action: Contact your network administrator.

Cause: Connection with host node was made but partner aborted
Action: Make sure object (see 06031, above) is working (for VMS run the command file and make sure that the ORACLE server process starts up); sometimes happens when the network/node is under stress – in this case a retry often works.
ORA-06035: NETDNT: connect failed, insufficient resources
Cause: Insufficient system resources are available to complete the connection; for example, all DECnet channels are in use.
Action: Contact your network administrator.
ORA-06037: NETDNT: connect failed, node unreachable
