19 * VIEWS, SYNONYMS, PROCEDURE, FUNCTION, PACKAGE,
20 * TYPE, LIBRARY.
21 * This mechanism can be used to allow lazy revalidation
22 * to take care of validating package bodies, type bodies
23 * triggers etc.
24 * TYPES_ONLY - Only recompile type specifications
25 * NEW_EDITION - Only recompile invalid objects in the current edition.
26 * This is useful for validating new or changed objects in
27 * a new edition that may have been left invalid by the
28 * installation process.

39 * NAME:
40 * recomp_parallel
41 *
42 * PARAMETERS:
43 * threads (IN) - Number of recompile threads to run in parallel
44 * If NULL, 0, or negative, RECOMP_PARALLEL computes a
45 * default degree of parallelism as the product of
46 * Oracle parameters "cpu_count" and
47 * "parallel_threads_per_cpu". On a Real Application
48 * Clusters installation, the degree of parallelism
49 * is the sum of individual settings on each node in
50 * the cluster.
51 * schema (IN) - Schema in which to recompile invalid objects
52 * If NULL, all invalid objects in the database
53 * are recompiled.
54 * flags (IN) - Option flags supported (as described above).
55 *
56 * DESCRIPTION:
57 * This procedure is the main driver that recompiles invalid objects
58 * in the database (or in a given schema) in parallel in dependency
59 * order. It uses information in dependency$ to order recompilation
60 * of dependents after parents.
61 *
62 * NOTES:
63 * The parallel recompile exploits multiple CPUs to reduce the time
64 * taken to recompile invalid objects. However, please note that
65 * recompilation writes significant amounts of data to system tables,
66 * so the disk system may be a bottleneck and prevent significant
67 * speedups.
