Oracle - Errores y soluciones
ORA-00023: session references process private memory; cannot detach session
Cause: An attempt was made to detach the current session when it contains references to process private memory.
Action: A session may contain references to process memory (PGA) if it has an open network connection, a very large context area, or operating system privileges. To allow the detach, it may be necessary to close the session's database links and/or cursors. Detaching a session with operating system privileges is always disallowed.
ORA-00024: logins from more than one process not allowed in single-process mode
Cause: Trying to login more than once from different processes for ORACLE started in single-process mode.
Action: Logoff from the other process.
ORA-00025: failed to allocate string
Cause: Out of memory.
Action: Restart with larger sga heap.
ORA-01008: not all variables bound
Cause: A SQL statement containing substitution variables was executed without all variables bound. All substitution variables must have a substituted value before the SQL statement is executed.
Action: In OCI, use an OBIND or OBINDN call to substitute the required values.
ORA-01000: maximum open cursors exceeded
Cause: A host language program attempted to open too many cursors. The initialization parameter OPEN_CURSORS determines the maximum number of cursors per user.
Action: Modify the program to use fewer cursors. If this error occurs often, shut down Oracle, increase the value of OPEN_CURSORS, and then restart Oracle.
ORA-00984: column not allowed here
Cause: A column name was used in an expression where it is not permitted, such as in the VALUES clause of an INSERT statement.
Action: Check the syntax of the statement and use column names only where appropriate.
