Hi,
Problem:
As i did not find any useful references about when ORA-10887 is raised or how to enter "Active Data Guard license" to make that error disappear ...
Symptoms:
1) Messages in alert.log during physical standby database startup or during switchover:
ORA-10887: An Oracle Active Data Guard license is required to open a pluggable database while standby recovery is applying changes.
ORA-10887 signalled during: ALTER PLUGGABLE DATABASE ALL OPEN...
2) Message while trying to open pluggable database manually on physical standby database:
SQL> alter pluggable database XXX open read only;
alter pluggable database XXX open read only
*
ERROR at line 1:
ORA-10887: An Oracle Active Data Guard license is required to open a pluggable
database while standby recovery is applying changes.
Configuration bits:
sql> select OPEN_MODE, DATABASE_ROLE from v$database;
OPEN_MODE DATABASE_ROLE
READ ONLY WITH APPLY PHYSICAL STANDBY
sql> select VERSION_FULL, STATUS, EDITION from v$instance;
VERSION_FULL STATUS EDITION
19.5.0.0.0 OPEN EE
