Change Sys Password

Change Sys password at primary and standby database (ADG) server:

+++++++++++++++++++++++++++++++++++++++++++++++++++++

step 1: cancel MRP process from standby database server

sql> alter database recover managed standby database cancel;

step 2: connect primary as 

sqlplus / as sysdba

sql> alter user sys identified by ISBySs#aDm1n$;

step 3: Rename the password file in standby database

cd $ORACLE_HOME/dbs

[oracle@test_db dbs]$ mv orapwSID orapwSID.back

step 4: send the password file to standby site

[oracle@test_db dbs]$ scp orapwSID oracle@192.168.4.44:$ORACLE_HOME/dbs/

step 5: apply MRP at primary database server

sql> alter database recover managed standby database disconnect from session nodelay; 

Oracle Error

~Oracle Error Troubleshooting

++++++++++++++++++++++
Error:
ORA-39127: unexpected error from call to export_string := SYS.DBMS_SCHED_JOB_EXPORT.GRANT_EXP(219179,1,...)

Cause: Oracle OLAP (Online Analytical Processing) may not be installed or not be configured properly.

Solution:

To solve the problem you may execute the following steps:

a) You might want to make a full backup of your database before attempting the following steps.
b) Remove workspace package from export:

step 1. Connect / as sysdba

step 2. ---(Backup sys.exppkgact$ before making any changes.)

create table sys.exppkgact$_backup as select * from sys.exppkgact$;

step 3. delete from sys.exppkgact$ where package = 'DBMS_CUBE_EXP' and schema= 'SYS';

step 4. delete from sys.exppkgact$ where package = 'DBMS_AW_EXP'  and schema= 'SYS';
step 5. commit;

Now export and check the export log

Troubleshot snapshot database

Troubleshoot snapshot database:
....................................................................
~Problem:
------------
When convert physical standby to snapshot database the following error can be raised.
Alert log error:
ORA-00313: open failed for members of log group 7 of thread 0

grep message from V$DATAGUARD_STATUS from standby database:

SELECT MESSAGE FROM V$DATAGUARD_STATUS;

RFS[4]: No standby redo logfiles created for T-1 dataguard

~Solution:
------------

Troubleshoot snapshot database technique is drawn below in the following steps. 
step 1:
crosscheck thread# from v$log and v$standby_log from both primary standby database.
SQL> SELECT thread#, group#, sequence#, bytes, archived ,status FROM v$log ORDER BY thread#, group#;

   THREAD#     GROUP#  SEQUENCE#      BYTES ARC STATUS
---------- ---------- ---------- ---------- --- ----------------
         1          1       2532  209715200 NO  CURRENT
         1          2       2530  209715200 YES INACTIVE
         1          3       2531  209715200 YES ACTIVE

SQL> SELECT thread#, group#, sequence#, bytes, archived, status FROM v$standby_log order by thread#, group#;

   THREAD#     GROUP#  SEQUENCE#      BYTES ARC STATUS
---------- ---------- ---------- ---------- --- ----------
         0          4          0  419430400 YES UNASSIGNED
         0          5          0  419430400 YES UNASSIGNED
         0          6          0  419430400 YES UNASSIGNED
         0          7          0  419430400 YES UNASSIGNED
step 2:
if mismatch then match thread# number in standby log according to thread# number of physical standby.
In standby:
alter database recover managed standby database cancel;

ALTER DATABASE DROP STANDBY LOGFILE GROUP 4;
ALTER DATABASE DROP STANDBY LOGFILE GROUP 5;
ALTER DATABASE DROP STANDBY LOGFILE GROUP 6;
ALTER DATABASE DROP STANDBY LOGFILE GROUP 7;

alter database add standby logfile thread 1 'path/stbr1.log' size 200M;
alter database add standby logfile thread 1 'path/stbr2.log' size 200M;
alter database add standby logfile thread 1 'path/stbr3.log' size 200M;
alter database add standby logfile thread 1 'path/stbr4.log' size 200M;
step 3:
startup mount force;

step 4:
alter database convert to snapshot database;

step 5:
alter database open;
