PAYYING ATTENTION ?

10. The name of these bundle patches was changed to "Database Proactive Bundle Patch"
in April 2016.
Each bundle patch includes the following component patches in separate
subdirectories:
• Clusterware component the same as GI PSU
• ACFS component the same as GI PSU
A database bundle component that includes all DB PSU fixes along with
additional fixes specifically for Engineered Systems and DB In-Memory

from dba_registry_sqlpatch;
Bundle_series column can has the values [ PSU | DBBP ]
Check all the pluggable database has all the patches.
SQL> alter pulggable database all open;
SQL> SELECT s.con_id, s.patch_id, s.patch_uid, s.description FROM
cdb_registry_sqlpatch s order by 1,2;
if not all pluggable databases are sync , what can I do ?

23. Management Repository (GIMR)
The Grid Infrastructure Management Repository is automatically installed with Oracle Grid Infrastructure
12crelease 1 (12.1.0.2). The Grid Infrastructure Management Repository enables such features as Cluster
Health Monitor, Oracle Database QoS Management, and provides a historical metric repository that
simplifies viewing of past performance and diagnosis of issues.
The -MGMTDB has now become a single-tenant deployment having a CDB with one PDB
Average growth size per day per node is roughly 650-750 MB. E.g. a 4 node cluster would lead at the default retention
of 3 days to an approximate size of 5.9-6.8 GB
