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;

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.

Backgroud info:
host server crashed.
Database was not cleanly shutdown.
Database is not in archivelog mode.
Datafiles were saved.
My goal:I want to recover the database based on the available files.
My approach:
Install new database.
ALTER DATABASE BACKUP CONTROLFILE TO TRACE.
shutdown database.
Place available dbf files in the location for new database, replacing existing files.
edit trace file to create new controlfile. Script is:
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "newdatabase" RESETLOGS NOARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292

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;}
Starting restore at 24-FEB-12
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=133 device type=DISK
channel ORA_DISK_1: starting datafile backup set restore
[code]...
Starting recover at 24-FEB-12
using channel ORA_DISK_1
starting media recovery archived log for thread 1 with sequence 2 is already on disk as file /u01/app/oracle/oradata/PROD/redo02.log
archived log file name=/u01/app/oracle/oradata/PROD/redo02.log thread=1 sequence=2
media recovery complete, elapsed time: 00:00:01
[code]...
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 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

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)?

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 ?

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?
