PDB doesn't take underscore parameters during database start

2789612Mar 15 2015 — edited Mar 16 2015

Hello


All underscore parameters which are set on a PDB level are ignored during database start.

An underscore parameter is set on a PDB level in memory and spfile. After restarting database the parameter is still in pfile but not anymore in memory.

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED

---------- ------------------------------ ---------- ----------

         2 PDB$SEED                       READ ONLY  NO

         3 Q00A                           READ WRITE NO

SQL> alter session set container=Q00A;

SQL> alter system set -_push_join_union_view-=FALSE scope=both sid='*';

SQL> show parameter -_push_join_union_view-

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

_push_join_union_view                boolean     FALSE

SQL> show spparameter -_push_join_union_view-

SID      NAME                          TYPE        VALUE

-------- ----------------------------- ----------- ----------------------------

*        _push_join_union_view         boolean     FALSE

srvctl stop db -d cdbq00r; srvctl start db -d cdbq00r

SQL> show parameter -_push_join_union_view-

no rows

SQL> show spparameter -_push_join_union_view-

SID      NAME                          TYPE        VALUE

-------- ----------------------------- ----------- ----------------------------

*        _push_join_union_view         boolean     FALSE

Thanks

Venkat
