Primary - Standby issue.

Hi,
bdump, cdump, udump, folders are accidentally removed from the primary database and the primary is not coming up now showing an error unable to create audit file.
The standby is also not working properly when i issue the command ALTER DATABASE RECOVER MANAGED STANDBY DATABASE FINISH.
It is showing a series of error messages:
alter database recover managed standby database finish
ERROR at line 1:
ORA-00283: recovery session canceled due to errors
ORA-01110: data file 1: '/u01/app/oradata/ARG/system01.dbf'

ORA-01115: IO error reading block from file 1 (block # 1)
ORA-27069: attempt to do I/O beyond the range of the file
Additional information: 1
Additional information: 1
Please help me come out of this situation.
Thanks,
Aswin.

Hi,
Comment all the parameters of AUDITING in the prameter file and start DB,Dont forget to creat cdump udump bdump directories.
If the primary database size is small u can just create the standby control file in primary database copy it to standby location,then copy all the datafiles of the primary to the standby location and put standby in managed recovery mode.

Primary & standby db on same OS plaform but having different OS version

Hi,
I have primary & standby database 10.2.0.4 on AIX 5.3 Operating System platform .
I would like to Upgrade my Operating System(AIX) of standby databse server from 5.3 to 6.0.
Will diffenet Operating System version for primary & standby databases support ?
Thnaks.

so, if my primary db on aix 5.3 & standby db on aix 6.1 plaform, then it will not work
or oracle db will not support for this differnent os versions.
is it right?Yes, along with that I'm asking why you want to choose different versions/releases of OS?
I seen there some issues even if some RPM's are missing. So if the complete version changes then think of it.
Moreover check the certification in support.oracle.com
Recently i checked for Linux 6, it's not yet certified. I'm not sure of unix here. So please do refer http://support.oracle.com
Thanks.

Switchover_status "FAILED DESTINATION" on both primary-standby databases

Hi,
I setup primary-standby databases and try to test the switchover functionality between them using the following commands:
alter database commit to switchover to primary with session shutdown;
alter database commit to switchover to physical standby with session shutdown;
Currently, both DBs are showing
open_mode= READ WRITE for "select open_mode_from v$database;" and
switchover_status = FAILED DESTINATION for "select switchover_status from v$database"
When both databases get into these states, how can I return them back to primary and standby roles? Could you please provide me a sequence of steps that I can execute to return them back to normal primary-standby states?
Thanks in advance for your suggestion.

The OS is Red hat 4.1.2-500.
Oracle version is 11g.
Here is the sequence of steps that lead to this issue:
1. switchover_status on primary = to standby, switchover_status on secondary = not allowed
So on primary, I execute
alter database commit to switchover to physical standby with session shutdown;
and could be shutdown/startup mount ( I don't remember exactly)
2. switchover_status on secondary = to primary
So on secondary, I execute
alter database commit to switchover to primary with session shutdown;
alter database open;
3. Now on secondary, the switchover_status = FAILED DESTINATION
On primary, I execute
alter database commit to switchover to primary with session shutdown;
and could be "alter database open" ( I don't remember exactly)
The switchover_status in step 1) and 2) above should indicates that the data guard is working. At the end of the above steps, I cause both databases to get into switchover_status = "FAILED DESTINATION".
I hope to get one of the DBs back into standby role.
If I execute "alter database commit to switchover to physical standby with session shutdown", I will get
"ORA-16416: No viable Physical Standby switchover targets available"
In this situation, is there any recommendation for rescue?

How to Refresh UAT Primary/standby from Production primary/standby

Hi ,
We have the following setup :
Primary/standby - Production
Primary/Standby - UAT
I need to know the process on how to refresh the UAT primary/standby .
I'm thinking on the following lines :
1] If we have the export dump of production , can we go ahead and drop the schemas to be refreshed on both UAT Primary and UAT Standby UAT then perform the schema import on Primary UAT .
2] In case if I have to do a full refresh of UAT , do I need to rebuild the UAT environment from the proudction backups Ie,
(i) Drop both the UAT primary and UAT standby database .
(ii) using the produciton backup built the UAT Primary . Take the UAT primary backup and build the UAT standby .
Appricaite if any one can provide some best practices to refresh UAT from Production.

That setup seems to be rare. We assume that the Standby Database is used for testing and have a feature for that called Snapshot Standby.
But in your scenario, you need to develop your own techniques for "refreshment of the UAT Primary".
An easy way (if your Primary is not too large): Throw away your UAT env each time the "Production Primary" changes and RMAN clone it to "UAT Primary" then.
Then RMAN duplicate "UAT Standby" again. Could be relatively easily scripted.
But again: Why not just create an ordinary Standby on your UAT hardware and use it for testing with Snapshot Standby feature? Much easier to maintain.
Kind regards

Dataguard 9iR2 using same SID for primary and physical standby issues

Hello, I have been following the Creating Physical Standby Database document from Oracle setting up a physical clone for a 9iR2 database on Solaris 9 environment between two identical workstations. I want to databases to have the same SID for relatively seemless failover however the redo logs are not pushed to the physical clone. when I switch a logfile on the primary and then query v$archive_dest on dest_id=2 I get a status of ERROR and the ERROR is the ORA-12154 TNS service name error.
Here is a summary of my setup:
Primary - SID = PROD1, located on WS001
Clone - SID = PROD1, located on WS002
SPFILE settings on Primary:
*.db_name='PROD1'
*.dg_broker_start=true
*.fal_client='PROD1_node2'
*.fal_server='PROD1_node1'
*.log_archive_dest_2='service=PROD1_node2 optional lgwr async=20480 noaffirm reopen=15 max_failure=10 delay=30 net_timeout=30'
tnsnames.ora on Primary:
PROD1_node2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = WS002) (PORT = 1521))
(CONNECT_DATA =
(SID = PROD1)
listener.ora on secondary:
PROD1_node2 =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = WS002) (PORT = 1521))
SID_LIST_PROD1_node2 =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /export/oracle/oracle_9.2/PROD1)
(SID_NAME = PROD1)
Any input would be appreciated. I can provide whatever else you might need. I thought this was the most pertinent to this problem.
Thanks.
Jim

I have been looking at the sqlnet.ora files for the two databases
for WS001:
Names.Default_Domain = WS001.example.com
Names.Directory_Path = (TNSNAMES, ONAMES,HOSTNAME)
for WS002:
Names.Default_Domain = WS002.example.com
Names.Directory_Path = (TNSNAMES, ONAMES,HOSTNAME)
I cannot connect with sqlplus from WS001 to WS002 on the other machine.

Logical Standby Issue

Hi Friends,
I have 4 doubts. Please help me to clear my confusion.
Doubt 1:-
I have one primary and one logical standby database. When i restart the primary database or logical standby database or whenever data is not transffering to standby database, I execute the package "EXECUTE DBMS_LOGSTDBY.BUILD;". Then it starts to transfer the data to standby. My question is executing this package many times will affect the primary database? or my configuration is wrong?
Doubt 2:-
I configured DGMGRL for both database and i can switch over and switch back to logical standby database. It automatically start to apply the data to new logical standby database. But when i switch back to old primary database, It didnt transfer the data automatically. So i execute the package "EXECUTE DBMS_LOGSTDBY.BUILD;" in primary. Then it starts to transfer the data. My question is my switchback is wrong? or it happens like that only?
Note:- I check the verbose of both database before switchback. It show success.
Doubt 3:-
When i check the switchover status in logical standby database, It show "NOT ALLOWED". Even though i can switch over by using dgmgrl. Why logical standby database showing "NOT ALLOWED"?
Doubt 4:-
Is it any possible to view that what commands executing by dgmgrl process in background while it switchovering to logical standby database.?
Because when i try to switchover manually it didnt work. Many times i tried. But in dgmgrl, I simply give "switchover to logdb;", It works.
Please help to me to understand clearly.
Thank you in advance.

Wrong forum mate. This forum deals with SQL and PL/SQL languages and related issues - not database administration and configuration issues.
The shared memory error is not unusual though ito SQL and PL/SQL. It is often a result of not using sharable SQL - in other words, SQL statements that are not using bind variables.
This causes additional consumption and fragmentation of shared pool memory. The very worse thing to do in this case would be to increase the size of the shared pool. That is akin to moving the wall a bit further away so that one can run even faster and harder into it.
But I'm merely speculating as you may have another cause for this problem. I suggest that you:
- post this in the [url http://forums.oracle.com/forums/forum.jspa?forumID=61]Database Forum
- research this error on [url http://metalink.oracle.com]Metalink

Oracle 10 upgrade - Primary & standby database

Hi Expert,
I need some information on your project experience. We're currently planning a oracle 10 upgrade. Have a few question:
1. We're planning to upgrade the primary database first and a week later the standby database. Will the archive log which is sent from primary to standby database will still work? Will the recovery still work?
2. Is this the right patch to go 10.2.0.4? I'm currently on 4.7 ext 2
3. Will there be a performance issue known of oracle 10 running on 32-bit machine, since it has the limitation of the memory (3G). Do I need to set AWE option on windows?
Thanks in advance.

Hello Sean,
please let me go more in detail with some of your comments.
> I actually posted my experience with doing a rolling upgrade of a PHYSICAL standby database.
This statement is wrong. You can't do a rolling upgrade with a physical standby database. You have to convert the database to a logical standby database .. and then you can perform a rolling upgrade. But if you have done the conversion, it is not a physical anymore.
This is also described and mentioned in this white paper:
http://www.oracle.com/technology/deploy/availability/pdf/maa_wp_10gr2_rollingupgradebestpractices.pdf
Data Guard SQL Apply (logical standby database) is required in order to perform a database rolling upgrade. You can also do a rolling upgrade when starting with a physical standby by temporarily converting the physical standby to a logical standby. If starting with 11g, see the Rolling Database Upgrades for Physical Standby Databases using Transient Logical Standby 11g paper for details on doing a rolling upgrade when starting with a physical standby. If starting with 10g, see MetaLink note 300479.1.
> It WILL work, and is fairly straight forward.
In this point you are almost correct, because of a standard SAP system is not using the unsupported data types, etc. (afaik)
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/data_support.htm
To be honest if a sap basis admin asks such a question, i would not recommend to perform an unsupported way, because i am in doubt about his dataguard know how.

Stefan

Primary/standby and 3rd archive log destination?

Running Oracle EE 10.2.0.4 linux 64 bit. I have a primary and standby configuration using data guard, with appropriate LOG_ARCHIVE_DEST_1, LOG_ARCHIVE_DEST_2 for the primary and standby - all works as expected. I want to multiplex the log files by adding a 3rd archive log destination to a different disk. I'm not clear on whether or not specifying a second 'primary' archive destination will write to both dest_1 and dest_3 or just alternate between the 2? I want to make sure that both DEST_1 and DEST_3 are written to (there can be a lag for DEST_3) -
Is the following all I need or are there additional parameters to LOG_ARCHIVE_DEST_n I'm missing?
LOG_ARCHIVE_DEST_3 = 'valid_for=(ONLINE_LOGFILE,ALL_ROLES)', 'location="/myThirdLoc"'
Thanks -

The database hang because of the redo log file is full. my test database is 16.7G and I gave the recovery filesystem 19 G for the redo log. Apparently it is not enough. After i set up the backup with daily incremental and run for 5 days, the recovery is full and db hang. How do you free up the space or set up the backup so that it can recycle the space? My DB is 10g r2 on RHEL3.

Need to re-organize the primary/standby servers

Our QA environment has two NODE RAC as primary(let's say on Chicago) and two node RAC as standby(on Boston).
Now during the testing procedures, find out application connection to Chicago Primary too slow, so they want to use standby BOSTON as primary.
How do I reverse them? This is a environment have not put in use yet.
Do I have to use dbca to create db on Standby BOston site , then create standby on Chicago primary site?
What is the best way?
Thank you in advance.

Switch over is only procedure,
you have some alternate options ( only for QA )
1) disconnect standby from primary "log_archive_dest_state_2=defer" ,
2) Create a snapshot/restore point on standby
3) perform failover on standby ( only standby conversion to primary)
4) users can able to connect to new primary,
5) once you done with that, restore that snapshot, it will flashback to the same position where you created a restore point
6) Then again enable "log_archive_dest_2"
7) make sure all the archives exist in primary, whenever you disconnected.
Do I have to use dbca to create db on Standby BOston site , then create standby on Chicago primary site?You want the same data of primary? or any new database will work for you?
If you are clear with this, then you have answer with you. If there is no concern on data then create a dummy database and give access instead of performing operations on DR & RAC site.
HTH.

T400 screen brightness standby issue

When my T400 comes out of standby the screen brightness goes to 100% even though the Power Scheme prior to standby was lower than 100%. This causes me to have to manually adjust the screen brightness. Does anyone know how to prevent this from happening? I have the ATI video adapter and I am making power setting changes via the Power Manager.

Is everyone running XP with this issue? I had the same problem when I got my brand new T400 and after 5 calls to tech support for this and quite a few other nuisance problems they gave me an RMA to send the thing back after I reloaded with an XP set they had sent me thinking I had received a bad copy of XP. Day before I was going to send it back I went to reload it again to get my info I had loaded off. Well for whatever reason I chose to load it with the Vista recovery discs instead and it took care of all of the nuisance problems!! I have no idea why but its not an issue now, all I can figure is whatever software is not checking the brightness when it comes back from standby doesn't properly run with XP as with my few other nuisance issues. I'm loading 7 this weekend, will update to let everyone know how it works.
(Other issues included the LAN/Bluetooh icons in the task bar next to the clock-even after telling them to "go away" in the properties they failed to do so. Sometimes the screen wouldn't even come back on after coming out of standby so I'd have to blindly shut it down and reboot. Wireless connection was sporatic and fingerprint softwarewas finicky in not letting me load fingerprints(that one was a driver update issue though)-Like I said, Vista took care of all of it, not that I'm endorsing Vista because I do bellieve Vista was a total failed attempt at an OS by Microsoft and was released WELL before it was ready and properly tested. My guess is the software/drivers for all the hardware with issues were developed under vista so it'll work with XP but doesn't like to and will be finicky....)

HELP! Variation on Standby issue

OK, so last week I closed the lid on my Thinkpad T400 running XP
After I opened the lid the screen just stayed black.
I had previously set the power manager so that closing the lid did nothing. In other words, my setting was that closing the lid was NOT supposed to standby the laptop.
Restarting did not help at all. After entering my PW at the cntl-alt-del screen, it would briefly show the wallpaper and then the screen would go black. Still does this. Seems like it is going into standby but not sure.
Finally hit on a workaround that works 40% of the time:
Start computer, at the cntl-alt-del screen put system into standby, let it sit, wake it up with power button, log on normally. Only works sometimes.
If I am at work and put it into the docking station it works fine; that is, my 2 external monitors work just fine, no need to monkey with anything..
To try and fix this I have:
- Updated BIOS
- Reinstalled Thinkpad power manager (and made sure I set it to NEVER go into standby)
- Reinstalled video driver
Nothing works, about ready to drop kick this laptop out the window.

Hi and Welcome to the Forums!
Wow...hard to decipher what you said there, but from what I can guess about it, it sounds like you have a BB on a corporate/enterprise BES system, and your system admin has restricted your ability to install 3rd party apps. There is no way around that...you must go see the BES admins and find out if they can relax that restriction.
Good luck!
