Backup & Recovery :: OCIServerAttach Returns ORA-1034 Even If Database Is Up And Running
Oct 9, 2012
We are using OCI call library to connect to Oracle database through one application. When we try to run this application through valgrind( a memory leak detection tool for linux) then, OCIServerAttach() call is failing to connect to db and it says that "ORA-1034 :Oracle not available"," Oracle instance may be down", etc. However, our oracle instance is running and database is open. When we run our application normally ( not through the tool) then everything is working fine.
I have a RUN file within a script to duplicate a database. As part of this RUN file I also run the command configure controlfile autobackup off; as part of this RUN file. However, this command has turned off backup of the control file on the AUXILLARY database (i.e. production) as well as the TARGET database (test). Is this supposed to happen?
My run file is:
rman TARGET sys/XXXX@${DB}-SOURCE AUXILIARY / RUN { allocate AUXILIARY channel a1 type disk; allocate AUXILIARY channel a2 type disk; allocate AUXILIARY channel a3 type disk; allocate AUXILIARY channel a4 type disk;

Debugging turned off
here's the trace files I logged

changing archive mode during DB running.Before in 9.2, 'ALTER SYSTEM ARCHIVE LOG START/STOP' is available for this job. But, after 10g/11g, it cause 'archive log stop has been deprecated'.
However, for my practice, I need to estimate archived logs size before backup them, so I need to stop archive log for a while and enable it later during DB running.
I check Oracle documents, it only mentions changing archive log mode at DB mounted but not open.
SQL> alter database mount; Database altered. SQL> alter database open resetlogs; alter database open resetlogs * ERROR at line 1: ORA-01139: RESETLOGS option only valid after an incomplete database recovery
My database is in NOARCHIVELOG mode.I took whole DB backup ( cold).Then just after half an hour I ran following script.
RMAN> RUN { RESTORE DATABASE;RECOVER DATABASE;alter database open;}

Why do I need to specify an option at the first place?As my redo is intact, it is not incomplete recovery and, I do not want to generate new incarnation of my database.Why oracle simply not opening my database?
I have oracle 10g installed on my system and name of the database is "ORCL" for which I have schedule the incremental backup everyday. Mentioned below are the steps followed

Now I want to restore this backup to some other system with new database. How to do this recovery to some other database on new system.
I have facing problem while taking backup on Windows 7 client of Oracle 11g R2 database. I have installed oracle 11gR2 for windows on windows 7 machine. I have created a directory like below in database.
On Database Server
SQL> create directory win_expdp_dir as 'd:expimp';
Directory created.
SQL> grant read, write on directory win_expdp_dir to lab;
Grant succeeded.
On Windows 7 machine (client machine)
D:appproduct11.2.0client_1BIN>expdp lab/lab@wbdata.wbh-db11g DIRECTORY=win_expdp_dir DUMPFILE=lab.dmp LOGFILE=lab.log Export: Release 11.2.0.1.0 - Production on Mon May 2 12:51:44 2011 Copyright (c) 1982, 2009, Oracle and/or its affiliates.

I have give all sharing rights on d:expimp directory. My main question is why i'm getting this error. Is there any thing missing in setup. how to take export on windows 7 client.
I am trying to clone a database on another server with different direcory structure. So that path on the source db server are /u04 whereas on on target db server it would be /u03.
Since this I am testing it on small database initially I have kept all datafiles, backup and archivelogs at /u04 and /u03 on the source and target db servers respectively Now I have copied the backups from source db server to target and since path is changed, I cataloged it
However during restore I am getting
Quote:ORA-19870: error reading backup
Here are the session details

I've read a lot about the different types of backup available with Oracle (hot and cold backup). However, I was thinking of a different way of performing this task. I'm currently using Windows Server 2008 R2 and Oracle 11g Standard Edition. I'd like to schedule an entire backup of my server via the utility "Windows Server Backup" (available for free).That way, I could recover my entire server with all the programs and files in case the latter crashes.I'm wondering if this solution could be used as a way of backing up (and recovering) the Oracle database. Should I still set up a regular hot backup with the Archivelog mode enabled in case some operations/transactions were being done at the time of the crash (for the data integrity)?

after i backup my database,i check the alert log ,i found the following errror:

online backup done thru RMAN.Suppose i am taking online backup of full database. During the backup, user's are inserting/deleting/modifying data. This data is getting stored as online archives. Once the database backup is finished, how these archives are applied to the database to make the database up to date.
Backup entire database, without archived logs, while the database is open for user activity and also This backup should be the base for an incremental backup strategy.
select rl.org_rollup_skey from (select fc.org_skey as "FC_ORG_SKEY" from IA.HIST_FCT_FCST_SLS fc inner join IA.DIM_ORG do on fc.org_skey = do.org_skey where do.org_nam IN ('101', '485','486')) p INNER JOIN IA.DIM_ORG_HIER h ON p.fc_org_skey = h.desc_org_skey inner join IA.FCT_FCST_SLS_ORG_ROLLUP rl on h.GPRNT_ORG_SKEY = rl.org_rollup_skey
Above join is taking is running forever even as subquery
(select fc.org_skey as "FC_ORG_SKEY" from IA.HIST_FCT_FCST_SLS fc inner join IA.DIM_ORG do on fc.org_skey = do.org_skey where do.org_nam IN ('101', '485','486'))
returns no rows and this subquery give result in 10 seconds according to me Full query should not take more tha 20 secs.
We are running a 5Tb database backup which takes really a long time to backup and impacts the performance in general during the backup. We got a DataGaurd database in place which we want to utilize to run the RMAN backup on to avoid performance impacts and just use DG database for backup and DR purposes. My Question is if we run the backups on DataGaurd Database, How would a RMAN DG database backup would clear the archive logs from Primary production and from DataGaurd Database during the backup process?
I need to restore a backup of database A from into Database B. Both have the same names. Database B is already up and running.
I have a full rman backup of Database A ( it was taken with a recovery catalog which I don't have access to now as it was deleted ). I just have the full backup pieces including the control files. Is it possible to recover this database into Database B from this stand point.
I was thinking
2. Shutdown database B 3. Mount database B. It has same name as Database A. 4. With RMAN restore controlfile. Will a new controlfile be created from the backup directory I have the rman pieces for the full backup in ?
Our application servers will be running a SELECT which returns zero rows all the time.This SELECT is put into a package and this package will be called by application servers very frequently which is causing unnecessary CPU.
Original query and plan
SQL> SELECT SEGMENT_JOB_ID, SEGMENT_SET_JOB_ID, SEGMENT_ID, TARGET_VERSION FROM AIMUSER.SEGMENT_JOBS WHERE SEGMENT_JOB_ID NOT IN (SELECT SEGMENT_JOB_ID FROM AIMUSER.SEGMENT_JOBS) 2 3 4 5 ; [code]....
Which option will be better or do we have other options?They need to pass the column's with zero rows to a ref cursor.
How one should know whether RMAN is using target database control file or using separate catalog database. Also what one should do if he dont have catalog users credentials.
I am studying Oracle Database Administration, Just I want to know that My database is in Noarchivelog Mode and database in shutdown mode, then How will take Full Database Backup?how will do the full backup now and how will do the Recover the database.
In the cold backup after database recovery(lost database or control file) we open database in reset logs.Then must and should take the backup of database. Because it will be generates the new redo logs and new SCN numbers.And updates the data file headers and current control file.
At same manor hot backup after database recovery we open database in reset logs. Then it take the backup of database.Is it mandatory? or necessary?
