Oracle Database Errors or Warnings from Error ORA-21523 to ORA-21602
ORA-21523: functionality not supported by the server (object mode only)
Cause: User attempted to use a functionality that the server does not support.
Action: Upgrade the server
ORA-21524: object type mismatch
Cause: The object type of the object is different from what is specified.
Action: Check the type of the object and correct it.
ORA-21525: attribute number or (collection element at index) string violated its constraints
Cause: Attribute value or collection element value violated its constraint.
Action: Change the value of the attribute or collection element such that it meets its constraints. The constraints are specified as part of the attribute or collection element’s schema information.
ORA-21526: initialization failed
Cause: The initialization sequence failed. This can happen, for example, if an environment variable such as NLS_DATE_FORMAT is set to an invalid value.
Action: Check that all NLS environment variables are well-formed.
ORA-21527: internal OMS driver error
Cause: A process has encountered an exceptional condition. This is the generic internal error number for Oracle object management services exceptions.
Action: Report this as a bug to Oracle Support Services.
ORA-21560: argument string is null, invalid, or out of range
Cause: The argument is expecting a non-null, valid value but the argument value passed in is null, invalid, or out of range. Examples include when the LOB/FILE positional or size argument has a value outside the range 1 through (4GB – 1), or when an invalid open mode is used to open a file, etc.
Action: Check your program and correct the caller of the routine to not pass a null, invalid or out-of-range argument value.
ORA-21561: OID generation failed
Cause: The handles passed in may not be valid
Action: Check the validity of the env, svc handles
ORA-21600: path expression too long
Cause: The path expression that is supplied by the user is too long. The path expression is used to specify the position of an attribute in an object. This error occurs when one of the intermediate elements in the path expression refers to an attribute of a built-in type. Thus, the OCI function cannot proceed on to process the rest of the elements in the path expression.
Action: User should pass in the correct path expression to locate the attribute.
ORA-21601: attribute is not an object
Cause: The user attempts to perform an operation (that is valid only for an object) to an attribute of a built-in type. An example of such an illegal operation is to dynamically set a null structure to an attribute of a built-in type.
Action: User should avoid performing such operation to an attribute of built-in type.
ORA-21602: operation does not support the specified typecode
Cause: The user attempts to perform an operation that does not support the specified typecode.
Action: User should use the range of valid typecodes that are supported by this operation.
Above are list of Oracle Database Errors or Warnings from Error ORA-21523 to ORA-21602 received while performing certain operation against Oracle Database or related products.
