The UTL_RECOMP system package is a utility package for recompiling database objects. You can use the package to verify the validity of database objects after an upgrade. You can call programs in this package to recompile all objects or objects with the specified schema in the database.
Applicability
This topic applies only to OceanBase Database Enterprise Edition. OceanBase Database Community Edition provides only the MySQL mode.
Considerations
- Only the
SYSuser can call this package. - When you call the
RECOMP_PARALLELorRECOMP_SERIALprocedure, make sure that no DDL operation is in progress in the system. Otherwise, exceptions may occur. - You can call this package to compile a variety of objects, such as procedures, functions, packages, triggers, and user-defined data types (UDTs).
- You can query the
ALL_ERRORSview for errors related to a single object that occur during object compilation. - You can query the
SYS.UTL_RECOMP_ERRORStable for system errors that occur during compilation.
Subprograms
The following table describes the UTL_RECOMP subprograms supported by the current OceanBase Database version.

| RECOMP_PARALLEL | Recompiles invalid data program units, such as packages, procedures, functions, and triggers, in parallel. |
| RECOMP_SERIAL | Recompiles database objects in serial. |
