Data Guard :: Configuration Show Success Status With 2 Databases On Same (or Local) Location
Apr 9, 2013
I have recently configure Data guard with Database 10g (10.2.0.4-64 bits) on Windows 2007 server.My Data Gurad Configuration show Success status with 2 databases on same (or local) location.My questions are
1-When I query SHOW PARAMETER LOG ARCH
DG_CONFIG(PRMDB)
ONLY 1 (PRIMARY DATABASE IS DISPLAYED ONLY NOT 2 DTATABASES
e.g. DG_CONFIG(PRMDB, STLDB)
2- How to check the log applied interval or time (either transaction by transaction, timing etc)

I tried a Data Guard setup on Oracle Databases (version 10.2.0.4.0, on RHEL)
Primary Database is db5
Standby Database is db6
By the time I created standby database, 3 archivelogs (sequence 11,12,13) were generated on primary which I copied over to standby database server
Now while querying v$archive_gap on the primary database these archivelogs aren't listed
However at the same time querying v$archived_log on either Primary or Standby Database also does not list them
1)
In such case do I need to register these archivelogs on standby database?
Or else do I catalog these archivelogs on standby database?
Also as soon as standby database is started in recovery mode as a part of setup, 1 archivelog (sequence 14) was shown on standby
Now this archivelog has different path than the archivelogs generated later (sequence 15, 16)and v$archived_log shows it is generated as a part of FAL request (FAL=YES)
Question are
1) why it was FALed while redo apply services were active?
2) why this particular archivelog only which is part of FAL request is generated at different location
Does it generate at standby_archive_dest rather than FRA when FAL=YES?
3) why subsequent archivelogs are not part of FAL request or FAL request wasn't needed for subsequent archivelogs?
Primary database init parameters
*.db_name='db5'
*.db_unique_name='db5'

I'm using oracle 10.2.0.3. on windows 2003. I've implemented physical stanby and it was working fine until last week. No problem on primary DB. Archived logs are sent normally to standby. And standby DB is also able to apply the archived logs coming from primary. I've already check data on standby DB after opening it with READ ONLY option : data are exported normally and I can read them.
The issue is the status of logs in view v$log on standby database.
select group#,status from v$log;
group# status
1 clearing_current
2 clearing
3 clearing
I've tried this :
On standby DB :
SQL> RECOVER MANAGED STANDBY DATABASE CANCEL;
Media recovery complete.
SQL> alter database open read only;
complete.
SQL> alter database clear logfile group 1;
Database altered.
SQL> alter database clear logfile group 2;
Database altered.
SQL> alter database clear logfile group 3;
Database altered.
SQL> select * from v$log;
GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS
---------- ---------- ---------- ---------- ---------- --- ----------------
FIRST_CHANGE# FIRST_TIM

1087538 25-OCT-11
3 1 0 5242880 1 YES UNUSED
1091468 25-OCT-11
I go back into recovery mode and my status says clearing_current.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
Database altered.
SQL> select * from v$log;
GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS
---------- ---------- ---------- ---------- ---------- --- ----------------

1091468 25-OCT-11

I know that the good status is ACTIVE or CURRENT or INACTIVE...

I have this scenario:
- Oracle 11.2.0.3
- RHEL 4.6 64 bits
- Active Data Guard
- Broker configured
- DBconsole configured on primary server
Now, I have server PRIM with the primary database, and server STB with the standby server. For now, the dbconsole is configured in the PRIM server.When I do a switchover (to the standby on STB), EM is not configured, so I use RepManager.sh to clean the sysman user, and I use emca to recreate the dbconsole. After this, everything works.
Once I switch back, the EM is no longer configured on PRIM, so I repeat the previous steps (repManager and emca). Everything is ok after this. I can access the EM on the primary normaly, and this gets information from the broker to provide basic information on the STB (like db status, apply, and so forth).

DB Version- 11.2.0.3
For the maximum protection and maximum availability as well as to enable Real Time Apply we need to setup the standby redo log group. My question is what would be the standby redo log group configuration in case if we setup single instance standby database for 2-Node RAC primary database. Do we require a separate standby redo thread for each primary online redo thread or RFS use the Multiple Standby redo group from the same thread to receive the redo changes from both the node ?

I did standby before and it works wighout any disturbations and even configuration seems to me not very complicated - but it was before. now i am trying to do standby configuration once again. there is database named DESK.
two physical serwers:
sczepl-db07 - primary
r00979 - standby
on each for this serwer there is listener listening on port 1521, and on each is tnsnames configured properly:
for sczepl-db07
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = sczepl-db07)(PORT = 1521))
[code]....
so why primary don't see standby db and claims that ther is no standby service? i proved that there is connection primary <--> standby.

We have a request to configure data guard for databases on the production server. Here is my situation:
We have a backup strategy in place where the backups are being taken on a regular basis. Archive logs are deleted as soon as they are backed up.
My question now is , is there a way of configuring the Data guard in such a way that there would be no change to existing backup strategy (RMAN) and still duplicate the archive logs to another destination and not delete the archive logs by RMAN backup process on that destination while the first destination is deleted.
We will be deleting the logs in the second archive destination using a script which checks if the logs were applied.

I have created dataguard between two instances hosted in two different servers. I have done switchover from primary to standby & then again standby to primary with DGMGRL utility.
1- When I done switchover to primary & trying to open standby database in readonly mode it was giving below error-
ORA-01154: database busy. Open, close, mount, and dismount not allowed now
Why this error was coming ?
2- As I was not able to open standby database in read only mode, I have executed below command-
alter database recover managed standby database disconnect from session;
which return an error as-
ORA-01153: an incompatible media recovery is active
After this I have executed-
alter database recover managed standby database cancel;
which executed successfully.
& then after standby database open in read only mode.
Why above error was coming ?
3- After this I had tried to check the checkpoint_change# & controlfile_change# from primary database and result shows both number were different.
Why they are not matching ?

Is it possible to detect the status of Hide / Show Region.
I have three hide/show regions RX,RY,RZ. When an event EX happens, then region RX should expand and the rest of the region should collapse. When an event EY happens, then region RY should expand and the rest of the region should collapse.
........
...
We can use this JS on DA to change the status of a region:
$("RX.uRegionControl").click();
$("RY.uRegionControl").click();
.....But, first we need to detect the status to know where to apply that DA. ? I am working on apex 4.2. theme 25.

We have taken export expdp backup from prod database (primary database- Data Guard).
1.) Import impdp is very slow 10GB/Hrs on staging database (Data Guard MAXIMUM AVAILBILITY)Since Server configuration, database version and configuration, operating system everything are same as production. No blocking, locking or waiting sessions
2.)import impdp is fast 90GB/Hrs on Test standalone database and this test database is running in NOARCHIVE LOG mode with oracle standard version after that no more difference.
CPU,Memory,network and disk I/O are look normal while importing on both databases.why that much difference on import.

current server - 4.0(approximately)
Migrating server - 160 MB
System tablespace

Migrating server - 220 MB
Also I checked the tables are also matching for the 4 databases.Also Provide the solution or method which is correct.

I need any good suggestion basically I have two different location
1- Factory
2- Head office
I have developed PRODUCTION module in factory and it is working fine and now I want to send data on daily basis to head office therefore I develop a form which will create backup in export format (.dmp) then user will send via email to head office.
Backup file should be save in pre-defined location then user will use a form which I developed for loading data into head office there are two different buttons in this form;
First is used to load data, actually first I load data in a temporary user which creates whenever user will press this button. Second is used to copy data in application user but first it checks if data exists then update otherwise insert.
