Oracle 12c R2 Error Codes and Solution Suggestions from ORA-02800 to ORA-02900

ORA-02800: Requests timed out

Cause: Some of the requests for asynchronous input or output were not serviced in the required amount of time.

Action: If the load on the system is high, it is possible that the timeout limit is too low. Reset it with sfainit(). If the server processes are dying due to unexpected signals, this is an internal error, and ORACLE support should be contacted.

ORA-02801: Operations timed out

Cause: Some asynchronous operations timed out in kernel mode.

Action: Internal error – contact ORACLE support.

ORA-02802: No idle servers available in parallel mode

Cause: Internal error.

Action: Check the UNIX number. If you are unsure about what it means, contact ORACLE customer support.

ORA-02816: Unable to kill a process

Cause: A server did not die after being sent a kill signal.

Action: The process may be a runaway – contact ORACLE customer support.

ORA-02817: Read failed

Cause: A server could not read a requested amount of data.

Action: Check the call to sfard(). An incorrect file descriptor may have been sent to sfard(). The number in the “additional information” field is the starting block number of the data segment being read in.

ORA-02818: Less than the number of blocks requested was read in

Cause: A server could not read in the request amount of data. The first number in the “additional information” field is the block number being read in. The second is the actual number of bytes that was read in.

Action: This is a programming error.

ORA-02819: Write failed

Cause: A server was unable to perform a write. The number in the “additional information” field is the starting block number of the data segment being written out. The first number in the “additional information” field is the block number being written out. The second is the actual number of bytes that was written out. The disk may have filled up.

Action: Check the UNIX error number.

ORA-02820: Unable to write the requested number of blocks

Cause: A server could not write the requested amount of data out to disk. The disk may have run out of space.

Action: Check the UNIX error number.

ORA-02821: Unable to read the requested number of blocks.

Cause: A server could not read the number of blocks that was requested. The end of the file may have been read.

Cause: A server was unable to seek to the designated block.

Action: Check the UNIX error number.

ORA-02823: Buffer is not aligned.

Cause: The buffer on which an I/O is being done is not on the correct boundary.

Action: Check the calling program.

ORA-02824: Request free list is empty

Cause: The list from which the package allocates request descriptors is empty because all of the descriptors is in use.

Action: Wait until some become free, or initialize the package with a higher number of request descriptors.

ORA-02825: Request on free list was not free

Cause: Internal error.

Action: Contact ORACLE support.

ORA-02826: Illegal block size

Cause: A negative number was given for the I/O block size to be used by the asynchronous I/O package.

Action: This is a programming error – use either a positive number or zero to get the default value.

ORA-02827: Invalid file number

Cause: The file number upon which an operation is to done is either less than zero or greater than the maximum number of files than can be open.

Action: This is a programming error. Since the calling program should not touch this number, this is a programming error.

ORA-02828: Segment free list is empty

Cause: No segments are available to allocated.

Action: Free some segments or shut down the package and re-initialize it with a higher number of segments.

ORA-02829: No segment of the proper size is available

Cause: No segment of the proper size is ready for use by the caller.

Action: Free some segments and try again.

ORA-02830: Segment could not be split – no free segments available

Cause: A segment that is larger than that desired could not be split because no free segment was available.

Action: Free some segments and try again.

ORA-02831: Segment deallocation failed – empty segment list

Cause: The caller attempted to deallocate a segment but the “in use” list was empty. This is a programming error.

Action: Check the calling program.

ORA-02832: Segment deallocation failed – segment not on list

Cause: The caller attempted to deallocate a segment that was not on the “in use” list. This is a programming error.

Action: Check the calling program.

ORA-02833: Server was unable to close file

Cause: A server was unable to close a file being used for asynchronous I/O.

Action: See the UNIX error number for more information.

ORA-02834: Server unable to open file

Cause: The server was unable to open a file for use with asynchronous I/O.

Action: Check the UNIX error number for more information.

ORA-02835: Server unable to send signal to client

Cause: Internal error.

Action: Contact ORACLE support.

ORA-02838: Unable to arm signal handler for the alarm signal

Cause: The arming of a signal handler for the alarmsignal failed.

Action: Internal error – contact ORACLE support.

ORA-02839: Sync of blocks to disk failed.

Cause: The server was unable to flush its writes out to disk.

Action: Check the UNIX error number.

ORA-02840: Open of log file by client failed

Cause: The client process was unable to open its log file.

Action: Check the UNIX error number for more information.

ORA-02841: Server died on start up

Cause: A server exited during its initialization process.

Action: Check the servers’ logs for more information.

ORA-02842: Client unable to fork a server

Cause: The client could not spawn a server. A possible reason is that the operating system has reached its limit on the number of processes that it can spawn.

Action: Either reduce the number of servers that are to be used, or reconfigure the operating system so that it can handle more processes.

ORA-02843: Invalid value for kernel flag

Cause: An illegal value was given for the kernel flag in the information structure. Only TRUE and FALSE are permitted.

Action: This is a programming error – check the calling routine.

ORA-02844: Invalid value for the leave open flag

Cause: A value was given for the flag that determines whether a file is to be left open after the client checks it to see if the servers can use it. Only TRUE and FALSE are supported.

Action: This is a programming error – check the calling routine.

ORA-02845: Invalid value for the timing wanted flag

Cause: A value was given for the flag that indicates that operations are to be timed out. Only TRUE and FALSE are supported.

Action: This is a programming error – check the calling routine.
