Database Is Not Connected To Application
Jan 4, 2013We have 11.2.0.3 RAC on Oracle Virtual Box,OEL 5.8. Storage is ASM on EMC SAN.Even when the database is not connected to application and thus open but idle and none is working on it, and all other virtual machines are powered off, we are still getting a continuous i/o in SAN.Since I am new to RAC setup I need to know the few things...
1.Is it normal behaviour?
2.If yes, what is the reason of this i/o? Is it due to continuous ping on voting disk?..write in OCR? automatic backup of OCR?

SQL & PL/SQL :: How To Identify Client Fired Query Still Connected To Database
Dec 21, 2011I need to get a way to find, The client fired the SQL Query is still connected to the database or not. For e.g.
I fire an SQL query using SQL Developer, Query approximately takes 5 mins to complete. As soon as I fire the query SQL devloper hangs and I close it using task manager.
Is there any way I can identify such session where SQL developer fired the query is terminated but the query fired is still running.
I have to identify such Orphan session and terminate it.
Networking And Gateways :: Authentication For Connected User Database Links
Jun 15, 2013I know how to use database links in various forms, but I've been trying to think through how the authentication works for a connected user link in 11g. If I create the link like this,
create public database link using 'orcl';
then any user can use the link, provided they have an identical username/password in the two databases. With pre-11g passwords, it was understandable: the password was salted with the username, so the hash of the password would be the same in both databases, and I assumed that the logon through the link used some sort of IDENTIFIED BY VALUES mechanism. But in 11g, the salt will different in the two databases. So the hash will be different. And of course Oracle never stores the actual password. So I don't see how the authentication works.
Server Administration :: Clone Database Cannot Be Connected After System Reboot
Oct 21, 20101. I installed oralce with Service_Name=DB1 it works fine,
2. I created another database with dbca named DB2,
3. I connected both system/password@db1 and system/password@db2 without any problem,
4. After rebooting the computer I can connect only the first database DB1 which I installed with Oracle installation. But, I can not connect to the 2nd database which I created with dbca. Error Message Shows: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
DB1 has no problem I can connect to that, but I can not connect to DB2 after rebooting the system. Now I need to know how to connect to DB2.

RAC & Failsafe :: Check How Many Sessions Connected To Particular Node
May 30, 2013I have few doubts in rac environment
1.In 2 node rac while adding datafile to tablespace if you forget to mention '+'then what will happen whether it is going to be create or it throws an error if it creates where exactly located and other node users how to work on that tablespace .what all steps to perform that datafile is useful for all node users.
2. In Rac environment how to check how many sessions connected to particular node.
3)In Rac any node is evicted due to network failure then after we rebuild the network .Is there any steps to do manually to access the failure node after rebuilding the network or it will automatically available in cluster group which service is perform this activity.
4.While configuring cluster ware you choose voting disk and ocr disk location and which redundancy you will choose suppose if you go for normal redundancy how many disks you can select for each file either one or two?

Detecting Full Domain Name / Username For Connected OS User
Oct 20, 2010If I'm looking on v$session - values in osuser column for some machines displayed with DOMAINNAME, and for other - without. Even same user (MYDOMAIN\ADMINISTRATOR) from 2 different machines displayed in 2 different ways on the same db:
MYDOMAIN\Administrator from machine A, and administrator from machine B.
Both machines are belongs to same windows domain. DB (oracle 10g) have no "DOMAIN" defined.
What make the difference? And can I somehow to affect this behaviour? I mean, can I define that all users will be displayed as DOMAINNAME\USERNAME or MACHINENAME\USERNAME(in case of no domain exists)?
Precompilers, OCI & OCCI :: Keep Connected To Oracle Or It's Better Reconnect After Work?
Feb 27, 2012I'm a beginner in the PRO*C and I have this issue/I have to maintain a multithreaded C++ PRO*C application and has the following structure
1) Application runs waiting for requirements
2) When detects a requirement it creates a Thread to work
3) The thread connects to Oracle with a EXEC SQL CONNECT :uid IDENTIFIED BY :pwd; instruction
4) Calls some anonymous calls to execute a stored procedure
EXEC SQL EXECUTE
BEGIN
commit;
:Status:=stored_procedure(:param1, :param2);
commit;
END;
END-EXEC;
5) If anything went wrong then issues a EXEC SQL ROLLBACK WORK RELEASE; then reconnects and the thread die
6) If everything was OK then the thread dies, but never called a EXEC SQL COMMIT WORK RELEASE; to disconnect from Oracle
I don't know why never the application disconnects from Oracle, maybe is for performance. Sometimes the application crashes and I believe that maybe the error is for never freeing the connections, the PROC compile line is this
proc parse=full sqlcheck=full user=system/manager cpp_suffix=cpp iname=source.pc include="..Hdr" include="C:ORACLEORA81ociinclude" include="C:ORACLEORA81precomppublic"
Which is the way to implement the connections?, connect and disconnect when done? or just keep the connection alive? Which way has better performance, connect and disconnect or just keep the opened connection?

View 6 Replies View RelatedDatabase Duplication Via RMAN
Nov 11, 2011I have 2 identical databases set up as follows:
- Version: Oracle 11gR2 (64 bit)
- OS: Windows Server 2008
- File System: ASM (with GRID Infrastructure)
Both instances are virtually identical... Same directory structures, same SYS passwords. The only thing that differs is the instance name (one is ABC, the other is XYZ).
Now, both databases are up and running, both have users on them, and both can accept remote connections. What I want to do is set up a very simple 'copy' system so that everything can be extracted (via RMAN) from the first database, and replace the database on the second. (Then, the user can log into XYZ with the same usernames/passwords they used on ABC.)
Here's what I'm doing so far:
On the 'source' database (ABC) I run RMAN as follows:
rman target / nocatalog
configure controlfile autobackup format for device type disk to 'C:\temp\CF_%F';
configure channel device type disk format 'C:\temp\bkp_%U';
run {backup database; backup archivelog all; }
Now, I'm not completely sure of what to do on the 'destination' database. I've seen multiple web pages with instructions that require the creation of a new instance using 'oradim' and the creation of a new password with 'orapwd'. However, is that necessary if I have the same sys password on both databases, and I want to use the same XYZ instance name on the destination machine?
Would it work if I used 'delete database' on the destination, and then used the RMAN 'Duplicate database to XYZ backup location 'C:\temp\'? Or does it HAVE to be a new instance created with oradim?
And if I DO have to use oradim to create a new instance, will the data be accessible through XYZ too?
