RAC & Failsafe :: Configure Oracle Dataguard For 2 Node Database
Oct 28, 2010We have to configure Dataguard for our 24x7 critical banking 2 Node RAC database(10.2.0.4). Before proceeding with the configuration we have to make sure what steps we should follow to have minimum or no downtime.
1) Document covering DG setup in RAC environment.
2) We have to perform switchover as well so need its steps too. Either the normal switchover steps would be used or have to stop/start rac services as well.
Dataguard Log Query
Dec 3, 2012This is my dataguard check script:
/home/oracle/bin/check
if [ $# -lt 1 ]; then
echo "usage: check <oracle_sid>"
echo
exit
fi
[Code]...
This is the output it gives on the primary:
INSTANCE_NUMBER INSTANCE_NAME
--------------- ----------------
HOST_NAME
----------------------------------------------------------------
VERSION STARTUP_T STATUS PARTHREAD# ARCHIVE LOG_SWITCH_WAIT
----------------- --------- ------------ --- ---------- ------- ---------------
LOGINS SHU DATABASE_STATUS INSTANCE_ROLE ACTIVE_ST BLO

[Code]....
SQL> Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options
This is the output it gives on the standby:
INSTANCE_NUMBER INSTANCE_NAME
--------------- ----------------
HOST_NAME
----------------------------------------------------------------
VERSION STARTUP_T STATUS PARTHREAD# ARCHIVE LOG_SWITCH_WAIT
----------------- --------- ------------ --- ---------- ------- ---------------

SQL> Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options
When I run the following:
SQL> select archivelog_change#-1 from v$database;
On the primary I get:
ARCHIVELOG_CHANGE#-1
--------------------
4902447998
On the standby:
ARCHIVELOG_CHANGE#-1
--------------------
4902447999
Which makes sense to me as my understanding of this is that the log is written, send to the standby, applied, then applied on the primary, yes?
So my questions are:
Why is there a lower entry on the primary (234) marked as opening, when it's closing 235, and writing 236, what does LNS mean?
Why is the second archive on the standby saying "CONNECTED 0" and do RFS, & MPR0 mean?
My init files say this:
Primary:
log_archive_dest_1='LOCATION=/u01/archive/prod/arch'
log_archive_dest_2='SERVICE=prod_stby LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=prod_stby'
Standby:
log_archive_dest_1='LOCATION=/u01/archive/prod_stby/arch'
log_archive_dest_2='SERVICE=prod LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=prod'

Active Dataguard Database
Jul 17, 2013I've got a physical standby database and I'm now licensed for Active DataGuard. I would like to automate the ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION command to be executed right after the STARTUP command so that whenever the database is started by our DBSTART script, it activates READ ONLY W/APPLY immediately after start without manual intervention. This is probably simple, but I figured I'd ask before starting to pore through documentation.....!

View 4 Replies View RelatedSQL Script Validation For Use In Dataguard Environment?
Feb 21, 2013We have a 10g environment with DataGuard running for reporting purposes. Our application team is getting ready to upgrade their application and it requires that several SQL Scripts be run to perform the primary database updates. A couple of them are over 1 MB in length. My concern is that these scripts will break DataGuard. I am not a DBA by any stretch, but I seem to remember there are certain limitations with DataGuard.
I have reached back to the team and asked them to have the Vendor confirm these scripts are validated for a DataGuard environment and I have also reached out to the System DBAs for review. I am wondering if there is an utiility available that can check the SQL to confirm if there are any DDL or DML statements that will not work in DataGuard. Likewise, we are going to run these scripts in a non-production DataGuard enabled environment first, but I want to have some level of confidence, that this will be a success.
Dataguard Setup Primary And Standby
Dec 2, 2011I have a dataguard setup, a primary and a standby.my instance is testdb.i have set all necessary dataguard parameters and everything seemed to work well initially with logs being moved from primary to secondary and being applied there.but all of a sudden i see that the primary pushes logs to the standby and at the standby end these logs are available but not applied.
when i try to execute the: alter database recover managed standby database cancel; it hangs for a long time and never returns to sql prompt.
i bascially want to stop and restart the MRP process to apply the logs but cannot cancel the managed recover mode.Is it advisable to kill the mrp process at os level using "kill -9 "?

But after a while, I can see some errors on primary alert log , and logs are not shipped anymore :

Jul 12, 2011I have setup 11g Dataguard - physical standby. Everything seems to be fine. I have also tested switchover and failover using DG broker which seems to work fine.All, I would like to know is abt ORA-01109 during switchover..
My config - RACprim- RACstby
Primary - TEST_prim (instances - TEST1, TEST2)
Standby - TEST_stby (instances - TEST1, TEST2)

New primary database "TEST_stby" is opening...
Operation requires shutdown of instance "TEST1" on database "TEST_prim"
Shutting down instance "TEST1"...
ORA-01109: database not open

This ORA error occurs when it tries to shut down primary. When primary is in open state, why its saying that database not open. Operation requires shutdown of instance "TEST1" on database "TEST_prim"..Shutting down instance "TEST1"..
Process To Refresh Schema In DataGuard Enabled Environment
Feb 21, 2013We have a non-production Oracle 10g Cluster running on Linux, with DataGuard (logical standby). From time to time, we need to refresh the schema on primary, but to do so as always caused problems with the logical standby. Our DBAs can never get it to complete successfully. They have tried a bunch of different methods (even provided from Oracle), but it does not work. e have a bunch of skip statements on the
Everytime, we need to refresh the schema, we have to build the entire database (primary and logical standby) from production RMAN backup. As you can imagine this is a very time consuming ordeal. There has got to be a way this process can be completed in a timely manner.
I was thinking of the following....
1) shut down dataguard, log shipping
2) lock user, kill sessions, drop user from primary
3) lock user, kill sessions, drop user from logical standby
4) run impdb on production export file on primary
5) run impdb on production export file on logical standby
6) re-enable dataguard, log shipping
7) confirm logs being applied, databases in sync
We are only replicating the one schema to the logical standby. I am not clear on how redo logs would be applied to the logical standby. There are hundreds of them @ 100 mb each, so I would think if we do this independently, I could somehow sync primary and logical standby after the imports complete.
DataGuard - Archive Log Apply Gap In Physical Standby Database
Nov 23, 20101) The Primary Database is UP. The Physical Stand By Database is DOWN. The Current Archive Log Sequence is 99 in Primary.
We have to apply Archive Log from 51 to 99 to the Standby Database. But Unfortunately, there is no backup of those Archivelogs and the ArchiveLogs from 51 to 98 have got deleted at Primary end.
Now how will you apply these Archive Logs from Primary Database to Physical Standby Database?
Note : The Physical StandBy Database is DOWN.

How To Configure Charset Unicode
Aug 15, 2012I need to configure character set for my database. I have 2 options:
AL16UTF16 - require 2 bytes per character (fixed length)
UTF8 - character length - 1 until 4 bytes. (variable length)
until here ok...
The AL16UTF16 certainly will occupy more space than UTF8. So my question is, When would I need use AL16UTF16 character set mode?
I hear one time, when a database write many values with the same length. it does it in the same HD cylinder. So the HD arm could with a single movement read all the fields in cylinder completely. Improving the read/write performance.

Configure Failover And Load Balancing?
Jun 28, 2013configure correctly my application, Oracle is version 11R1
My physical configuration is :
Site 1 (main building)
database on cluster : server1, server2
database : BASE1 available
Site2 (Backup Site)
database on cluster : server3, server4
database : DGBASE1 not available for users (dataguard)
I want to acces BASE1 first in load balancing server1,2 (normal usage) and DGBASE1 in load balancing server3,4 in case of failover after 5 retries of 10 secondes (in case of main buiding out of order, DGBASE1 will be available for users)
This is my actual setup :
(DESCRIPTION_LIST=(FAILOVER=ON)
(DESCRIPTION=

My trouble is that with this configuration, access it randomly BASE1 or DGBASE1 but DGBASE1 is not available for users then I have failure
What could be the right configuration to obtain BASE1 first in load balancing (normal usage) and DGBASE1 in load balancing in case of failover of the BASE1 after 5 retries of 10 secondes ?
