Data Guard :: Delay=60 Not Working In 11.2.0.2?
Mar 20, 2013
I am using 11.2.0.2 Data Guard.
I had set Delay=60 for Standby Database in init parameters of Primary Database and bounced both Primary and Standby DB.
But as soon as i perform log switch in Primary DB it is being applied in Standby DB immediately ignoring my Delay parameter.
The Physical Standby is mounted and redo apply is enabled.
Parameters:
-----------------
LOG_ARCHIVE_DEST_1=
'LOCATION=/data/dg/arch1/chicago/
VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
DB_UNIQUE_NAME=chicago'
LOG_ARCHIVE_DEST_2=
'SERVICE=boston ASYNC DELAY=60
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=boston'
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
Standby:

My standby database was working fine which was running in maximum performance mode .Suddenly i found that logs are not being applied though archived logs are received from primary database.i issued the command in mount mode: alter database recover managed standby database disconnect from session;
altered database this command runs successfully. but MRP process in not initiated which i confirmed with the query (select process,status from v$managed_standby;)

I have a 10gR2 standby database.Normally when logs are created in primary they automatically get shipped to standby but sometimes I get FAL request rejected or connection lost contact error and the logs are not automatically shipped .
Then when I manually switch a logfile the RFS process copies the old logs into DR site(around 4 or 5 logs).What is the problem...How to resolve this???

What could be the reasons that some queries execute fast when executed on sqlplus on server, whereas the same queries run slower with same input values fed from application screen?
One issue I guess would be bind variable peeking while using application whereas executing from sqlplus is causing hard parsing and thus getting rid of "peeking"
If displaying the data on application screen is taking time after data has been fetched, where I can see this delay?
I understand the elapsed time under 'Fetch' in tkprof will show time taken to fetch from database and not the time taken to be displayed in the application GUI
finally how to set arraysize in jdbc to improve performance by reducing roundtrips?

Controlling User Access to Tables in a Logical Standby Database can be controlled using the following command:
ALTER DATABASE GUARD STANDBY;
My simple question is: how can I know the current active Guard setting in the standby database?

we have a problem with forms containing webutil - they start very slow, after like a timeout, while forms without start ok. since i think it has something to do with name resolution i'll first describe our environment.
we have an external net with users, ip range 10.48.x.x, connected to a cisco router which is resolved in that network with the name 'cro'. so the users from that external net access us via 'http: //cro/.....'.
behind that router we have our production net, ip range 192.168.x.x, with forms-, reports- and http-servers. external users accessing our forms server will have to klick a link "http: //cro:8888/forms......'. that way they acces the cisco router which, depending on the port (here 8888) will NAT them to the correct forms server, say http: //forms1:7778/forms....' - up to here everything works well and fast with 'normal' forms (eg. without webutil).
forms *with* webutil on the other hand take like 30-60 seconds to load from that external net (via the router) while they load fast when called from a test-client in the internal 192.168.x.x net. after searching i found [URL] with a hint to alter the clients hosts file.
what i've found out so far is that the clients from the external 10.18.x.x net try to name resolve the *forms servers* in the internal net 192.168.x.x - i can cheat them by providing a fake hosts file which resolves the server named forms1 to the ip of the cisco router cro, but thats a temporarily and bad solution since i cant do that to real clients because i have no access to them.
so... how can i tell a webutil loaded form not to try to connect to the server they are started from (forms1) but to use the host they have been given to start from (cro)? or is there any other solution (which ofc cant include fiddling with the external net or external clients)?

in my application I'm starting jobs via dbms_scheduler for background activity on user action.
I know from my logs that the procedure executed in the job finishes within 2 seconds.
But in the AWR I find execution time for the job of 360 seconds (single execution because of unique job id).
How do I find out why the job takes so long?
And more important: how do I speed up the job?
(details will follow...)

I have written a stand alone (Java SE 1.6) JMS client program to consume AQ's messages via Oracle JMS API (aqapi.jar). The queue is a multiple consumer queue, and i just created one subscriber on it. My JMS client program receives messages asynchronously by setting the MessageListener using the setMessageListener method.
Watching the work of the program, I found significant delays in receiving messages that are up to several seconds. When I turned on the diagnostic trace, I found that in the absence of messages listener (AQjmsSimpleScheduler) gradually increases the delay time up to 15 seconds:
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsSimpleScheduler.feedData: Got a non null message, the sleep time is reset to 0
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsListenerWorker.run: sleep 0 millisecond.
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsSimpleScheduler.feedData: Got a null message, the sleep time is doubled to 1000
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsListenerWorker.run: sleep 1000 millisecond.
Thread-1 [Mon May 06 22:14:23 MSK 2013] AQjmsListenerWorker.doSleep: try to wait for 1000 milliseconds
[code]....
Thus, in the worst case, the delay between placing the message in the queue and receiving it by the JMS client is 15 seconds.
Can I control this latency? For example, I would like to explicitly set the levels of the time delays.

3)create control file for primary from trace(script) make changes for db name and file locations
4)mount and open primary database
5)create standby control file
6) transfer standby control file to standby

1. Can i rely on real time data recovery from SAN2 ?
2. if SAN1 (Data Files are currupted) will the SAN2 Data Files will be currupted as well.
3. If the SAN2 is currupted then what Oracle Features can be used to have uncurrupted data.

Our organization has recently decided to go for storage metro cluster solution for disaster recovery. In a Data guard environment, we normally calculate how much archive log is generating and based on that value we calculate the required bandwidth.
For storage metro cluster, we need to find how much block is changing in our primary database, and the same rate of change would apply on DR cluster. Now, i need to give the assumption how much changing is happening in my system. How to calculate the change.

I have installed Oracle server and SQL Server on separate machines which cause me a time delay of 21 seconds for each execution. Why executions delay? I have set RPC out (true).
Note: My main concern is either if the query is correct/incorrect it executes for 21 seconds._
Another case when I have both servers on the same machine it executes in milliseconds. I have tried Following methods in SQL SERVER.
*1, Using OPENQUERY:*
SELECT * From OPENQUERY(Linked Server Name,’Select * from OracleTableName ‘)
*2, Using Exec:*
DECLARE @sql NVARCHAR(MAX);
SET @sql =(’Select * from OracleTableName ‘);
EXEC (@sql) AT Linked Server Name ;
How to reduce the time delay caused for the execution?

I am very new to data guard...I have a primary and a physical standby database...If the primary got crashed, are the users directly switched to physical standyby (is it automated) or the DBA has to manually do the fail over or switch over....is it the same concept as in RAC like TAF....How can the DBA know that the users are disconnected from the database.....explain with some steps...
the version is 10.2.0...
