The best Oracle News for FY2026

Oracle Database 26ai will be available on generic Linux platforms in January and soon on AIX and Windows

Purpose This script provides a packaged interface to recompile invalid PL/SQL modules, Java classes, indextypes and operators in a database sequentially or in parallel.

This package can handle the recompile of any database or container with the sole exception of PDB$SEED which is, by definition, READ ONLY. If PDB$SEED contains invalid objects your database is toast or, at the least, PDB$SEED, is unusable.

PARALLEL_SLAVE

Runs in each parallel thread to recompile invalid objects from utl_recomp_sorted utl_recomp.parallel_slave(flags IN PLS_INTEGER);

exec utl_recomp.parallel_slave(2);

POPULATE_UTL_RECOMP_SKIP_LIST (new 23ai)

Undocumented

Relocated from UTL_RECOMP2 in 21c utl_recomp2.populate_utl_recomp_skip_list;

exec utl_recomp2.populate_utl_recomp_skip_list;

      

      PL/SQL procedure successfully completed.

PREP_RECOMP (new 23ai)

Calll before recomop_parallel to preemptively invalidate objects that would be invalidated during recomp_parallel utl_recomp.prep_recomp(schema IN VARCHAR2 := NULL);

exec utl_recomp.prep_recomp;

      

      PL/SQL procedure successfully completed.

RECOMP_PARALLEL

Recompiles all objects using 4 parallel threads utl_recomp.recomp_parallel( threads PLS_INTEGER := NULL, schema VARCHAR2 := NULL, flags PLS_INTEGER := 0);

exec utl_recomp.recomp_parallel(4);

      

      PL/SQL procedure successfully completed.

Recompile schema objects using the default degree of parallelism exec utl_recomp.recomp_parallel(NULL, 'UWCLASS'); PL/SQL procedure successfully completed.

Recompiles all objects using 2 parallel threads and allows other applications to use the job queue concurrently exec utl_recomp.recomp_parallel(2, NULL, utl_recomp.random_order); PL/SQL procedure successfully completed.

RECOMP_SERIAL

Recompile all objects sequentially utl_recomp.recomp_serial;

exec utl_recomp.recomp_serial;

      

      PL/SQL procedure successfully completed.

Recompile all objects in a schema sequentially utl_recomp.recomp_serial( schema IN VARCHAR2 := NULL, flags IN PLS_INTEGER := 0);

exec utl_recomp.recomp_serial('UWCLASS');

      

      PL/SQL procedure successfully completed.

TRUNCATE_UTL_RECOMP_SKIP_LIST (new 23ai)
