Cannot Connect To Database After Switchover Without Making Changes In TNS Entry
Nov 19, 2011
I have an issue of not able to connect to the database after switchover without making changes in TNS entry after the switchover when I try to connect to then the primary database (which is standby before ) , the tns entry has entries for both the primary and secondary but the order of the primay and seconday database is to be changed manually till then it keep showing ERROR: ORA-01033: ORACLE initialization or shutdown in progress.
Previously it is working fine but today when i am trying to duplicate a database using rman not getting exactly error but the o/p is as below
C:Usersdbadmin>rman target sys/tiger@na Recovery Manager: Release 11.2.0.1.0 - Production on Thu Jun 27 15:33:33 2013 Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved. connected to target database: NA (DBID=1572981579) RMAN> connect auxiliary sys/tiger@da connected to auxiliary database: NOIDA (DBID=1572981579, not open)
It is correct that the rman is connected to the db with name na but not with db da Previously i am able to connect both the instance.
we have a created primary and physical standby databases. Before the switchover the application connected to dataguard allows updates on the database. However after the switchover, it allows read-only access and we are unable to update. Any comments prima-facie ?
I am having setup of 2 node 10.2.0.4.0 RAC setup on ASM with Single Instance Physical standby on File System (OS: RHEL 5.4). I configured DG Broker without any major issues. Getting all output of 'show configuration' and all DG related logs are clear. Archives are getting transferred from both Primary nodes.
Now I am getting error Error: ORA-16535: CRS is preventing execution of a broker operation.
DGMGRL> switchover to livedg; Performing switchover NOW, please wait... Error: ORA-16535: CRS is preventing execution of a broker operation
Oracle Says
Quote:Cause A broker operation was underway that required CRS to stop managing the instances of this database, but CRS management could not be stopped on behalf of the broker"s request on at least some of the instances, so the broker operation was canceled.Suspend CRS management of this database using SRVCTL STOP DATABASE -D <name> -O NONE. Then reissue the broker request.But this command is not working as it's given to stop the database.
One more thing, it's nowhere said to stop CRS while performing Switchover / Switchback using DG Broker. When we do Switchover / Switchback we keep open only one of the Primary instance.
is there any documentation / link available to switchover of RAC database using dgmgrl (DG Broker)
Acer laptop, Intel Processor w/ Windows 7 Professional (64-bit) Delphi 2010 Professional Oracle XE (+ the Oracle XE client that comes with it)
I cannot can't to the Oracle database from Delphi. The error I keep getting is:
Alias is not currently opened. [Oracle][ODBC][Ora]ORA-12154:TNS: could not resolve the connet identifier specified.
Here's what I've done:
1. Create an ODBC connection to my Oracle database
- run C:WindowsSysWOW64odbcad32.exe to open the ODBC administrator. - Data source name: bt_user - TNS Server Name: localhost/xe - user bt_user - Clicked "test connection" -- Success.
2. Open Delphi and drop a TDatabase component on my main form.
- Set the Alias Name property to "bt_user" (the alias I set up in ODBC) - Set database name to "bt_user". - Checked "connected".
Alternatively, I tried using the Delphi ADO components (the dbGo components).
- Drop TADOConnection component on my form. - Select "connection string" and open the dialog. - Click "build string". - Select "Microsoft OLE DB Provider for ODBC Drivers" from the selection. - In "use data source", select "bt_user" from the drop-down list (my ODBC connection from #1) - Click "test connection".
Again the same error.
My questions are:
1. Can Delphi work with Oracle XE (Express Edition)?
2. If so, then do I need to install the "Instant Client"?
3. Will the instant client for Oracle 10g work with Oracle 10g XE?
4. Do I need to install any additional ODBC driver(s)?
5. Why was I successful in creating the ODBC connection in Windows, but it failed in Delphi?
6. Will Visual Studio.NET (C#) work with Oracle XE, and what are the steps for setting that up?
Suppose that, I have two tables: emp, dept emp records the empid, emp_name, deptid dept records the deptid, dept_name
Here is a record, it's a president or some special position in company, so it's deptid is set to NULL. Here comes the question, how can I print all the emp_name with their deptartment name?
I know how to print all the emp_name with their department name if they have dept_id, but is that possible that I merge the record with dept_id NULL?
- 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).
I have a dataguard configuration (physical standby).Database A is the primary database and database B is the standby database (I do not use the broker).Both are Oracle RDBMS 12cR1 EE. The Apply process uses the current log (standby redo logs).On database B, when querying v$managed_ standby;, I get:
It works fine. Before to perform a switchover,- from database A (current physical database), I get switchover_status = 'TO STANDBY'- from database B (current standby database). I get switchover_status = 'NOT ALLOWED'. What switchover_status = 'NOT ALLOWED' means exactly and how to get further with the switchover?
I need to build a query on making a vertical records to horizontal records. I did read somewhere saying that we can use decode function. But im still trying to understand how decode function can make a vertical records to horizontal records.
i have written an sql to look as sales orders but i want it to only return the last 12 months worth of sales for the date its run, the date file [sdtrdj] is julian date so i used to_char to conver it to dd-mm-yyyy how can i get it to only return the last 12 months from the date its run

I am fairly new to Oracle and have recently started learning the basics of Data Guard. I have set-up a Primary 11g database which successfully ships and applies logs to a Single Standby (on the same server) as expected. Manual switchovers work fine; however, I have found a slight problem when performing switchovers using the Data Guard Broker utility.
The switchover is successful- but the broker cannot restart the Primary instance. The strange thing is that when I perform a switchover in the opposite direction (i.e. the new Primary goes back to standby again) it works fine. The error is receive is: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
The majority of posts I have seen on this topic seem to point to incorrect listener / tnsnames set up but they have exactly the same values. If both databases are identical, why does it work one way but not the other? I will provide any necessary files to pinpoint where the issue could be.
i have a db's in maximum protection mode and i am trying to perform a switchover of physical standby database to primary role. but it failed., the steps followed is as follows. everything is fine with old primary site and the it is now in mounted state. When I went through the log file, I got the error message as "ORA-16072: a minimum of one standby database destination is required".the standby_archive_dest is as follows.
old primary database
SQL> alter system switch logfile; SQL> alter system archive log current;
old standby database...Disconnect the managed recovery mode in Standby database.
SQL> recover managed standby database cancel; Media recovery complete. SQL> recover standby database; AUTO SQL> exit [code]....
I am going through the Oracle VSS writer , trying out various methods. Just keen to know if this is the right place to ask VSS related questions as I could not find any post related to VSS.
For Volume based VSS shadow copy backups for a logged database, I am unsure about the restore method using VSS writer. Also oracle doc does not mention any steps for volume based restore of a logged (archive log mode db) database.
Got Active DataGuard on a primary database, quite nicely sending its archive logs to its secondary. I can quite happily use the Broker and switchover between them.
Now if I take RMAN backups of the primary database, if I have to failover to the secondary, I'm gonna loose all those backups.
Well, I can restore the whole database to the backup, cos I can restore the control file, from the backuip and therefore I can restore the whole db.
But if I want to restore to a tablespace, I wont be able to , cos the db_unique_names names are different, and the DB ID's will be different.
Same goes if I use a recovery catalog....
so how do I failover/switchover without loosing my previous rman backups ??
I created a script to make my admin server a windows service. I successfully made it a service but when it starts it then shuts itself down. i ran a debug and found a error. I dont get what to do. I have tried changing the variables in the script and try it over and over again .....here is my script code and here is the error i got from debug output:
script
SETLOCAL set DOMAIN_NAME=FRClassicDomain set USERDOMAIN_HOME=C:/Oracle/Middleware/user_projects/domains/FRClassicDomain set SERVER_NAME=FRweblogic
For example, I have 3 database, database 1 and database 2 connect together by database link db_link1, database 2 and database 3 connect together by database link db_link2.
I want to ask: Can I connect from database 1 to database 3 ? ( Of course don't use database link between database 1 and 3, just use database db_link1 and db_link2 )
Both db_link1 and db_link2 are public database link.
Can I restrict user access by 2 these public database link ?
I am not able to connect to database due to ORA-257. So manually i deleted the archivelog files in diskgroup. however it is showing 13gb free space after deletiion. Archive log files generated due to Import job is running.
In below ways i have tried to connect to database.
1) Through SQLPLUS (Not able to Connect) 2) Through RMAN i tried to connect (Not able to connect) 3) I tried to connect impdp to stop the running job. It was also failed
ORA-00607: Internal error occurred while making a change to a data block ORA-00600: internal error code, arguments: [4194], [89], [83], [], [], [], [], []
I do not know how to create a connection between oracle to SQL server using topology manager on my application. I understand that I must create a logical and physical architecture to create the connection and the logical and physical architecture is running under topology manager.
I extracted the script of creating user in my database in SQL navigator and Toad tools but it is displaying encrypted password. But I am unable to connect with that password.
To get the original password then I will be able to connect my database.
I'm writing PRO C program with oracle 8i. My process first connect to the database with using ora_connect(), proceed the task then diconnect with using ora_disconnect(). This would always in a loop, recently after few cycle of connect and disconnect, when the next issue connect statement, it was unable to connect and return me ora-00604 and the process end. Even i restart the process, after few cycle also the same return me ora-00604 during the connect.
