Common Oracle error codes

ORA-01650: unable to extend rollback segmentname by NUM intablespace NAMECause: the preceding ORACLE error is caused by insufficient tablespace In the rollback segment, which is also the most common ORACLE error message of the ORACLE Data Administrator. When a user is performing a very large data operation, resulting in insufficient existing rollback segments, the table space of the available rollback segments is full and cannot be allocated, the preceding error occurs.

ORA-01652: unable to extend temp segment by num in tablespace nameCause: the tablespace in the temporary ORACLE segment is insufficient, because ORACLE always tries its best to allocate continuous space. This problem occurs when there is not enough allocable space or the allocation is not consecutive.

ORA-01628: max # of extents num reached for rollback segment numCause: this error is usually caused by a rollback segment and a tablespace that has reached the limit set by the MAXEXTENTS parameter. Note that MAXEXTENTS is not the hardware limit of the rollback segment or tablespace. The hardware limit depends on the value of the DB_BLOCK_SIZE parameter specified in the init. ora file when the database is created.

ORA-01688: unable to extend table name. name partition NAME by NUM in tablespace NAMECause: the specified tablespace is full and cannot be expanded.
