Database recovery issue

Hi ,
trying to restore and recover a whole database with rman
I have done the following steps
1 - restored the controlfile
2 - got the scn number to restore to
3 - started the restore of the database with the following rman command
the scn number is generated from this command and this is taken from the restored controlfile.
SQL> select archivelog_change#-1 from v$database;
ARCHIVELOG_CHANGE#-1
29432527
RMAN> run{
set until scn 29432527;
restore database;
recover database;
alter database open resetlogs;
}however I get the following errors part way through the restore
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

Problem in performing multiple Point-In-Time Database Recovery using RMAN

Hello Experts,
I am getting an error while performing database point in time recovery multiple times using RMAN. Details are as follows :-
Environment:
Oracle 11g, ASM,
Database DiskGroups : DG_DATA (Data files), DG_ARCH(Archive logs), DG_REDO(Redo logs Control file).
Snapshot DiskGroups :
Snapshot1 (taken at 9 am): SNAP1_DATA, SNAP1_ARCH, +SNAP1_REDO
Snapshot2 (taken at 10 am): SNAP2_DATA, SNAP2_ARCH, +SNAP2_REDO
Steps performed for point in time recovery:
1. Restore control file from snapshot 2.
     RMAN> RESTORE CONTROLFILE from '+SNAP2_REDO/orcl/CONTROLFILE/Current.256.777398261';
2. For 2nd recovery, reset incarnation of database to snapshot 2 incarnation (Say 2).
3. Catalog data files from snapshot 1.
4. Catalog archive logs from snapshot 2.
5. Perform point in time recovery till given time.
     STARTUP MOUNT;
     RUN {
          SQL "ALTER SESSION SET NLS_DATE_FORMAT = ''dd-mon-yyyy hh24:mi:ss''";
          SET UNTIL TIME "06-mar-2013 09:30:00";
          RESTORE DATABASE;
          RECOVER DATABASE;
          ALTER DATABASE OPEN RESETLOGS;
Results:
Recovery 1: At 10.30 am, I performed first point in time recovery till 9:30 am, it was successful. Database incarnation was raised from *2* to *3*.
Recovery 2: At 11:10 am, I performed another point in time recovery till 9:45 am, while doing it I reset the incarnation of DB to *2*, it failed with following error :-
Starting recover at 28-FEB-13

ORA-15012: ASM file '+DG_REDO/orcl/onlinelog/group_1.257.807150859' does not exist
Doubts:
1. Why did recovery failed 2nd time, but not 1st time and why is RMAN looking for online redo log group_1.257.807150859 in 2nd recovery ?
3. I tried restoring control file from AutoBackup, in that case both 1st and 2nd recovery succeeded.
However for this to work, I always need to keep the AutoBackup feature enabled.
How reliable is control file AutoBackup ? Is there any alternative to using AutoBackup, can I restore control file from snapshot backup only ?
4. If I restore control file from AutoBackup, then from what point of time/SCN does RMAN restores the control file ?
Please help me out in this issue.
Thanks.

Hello experts,
I'm little newbie to RMAN recovery. Please help me in these doubts:
1. If I have datafiles, archive logs & control files backup, but current online REDO logs are lost, then can I perform incomplete database recovery ?yes, if you have backups of everything else
2. Till what maximum time/scn can incomplete database recovery be performed ??Assuming the only thing lost is the redo logs, you can recover to the last scn in the last archivelog.
3. What is role of online REDO logs in incomplete database recovery ? They provide the final redo changes - the ones that have not been written to archivelogs
Are they required for incomplete recovery ?It depends on how much incomplete recovery you need to do.
Think of all of your changes as a constant stream of redo information. As a redolog fills, it is copied to archive, then (eventually) reused. over time, your redo stream is in archivelog_1, continuing into archvivelog_2, then to 3, and eventually, when you get to the last archivelog, into the online redo. A recovery will start with the oldest necessary point in the redo stream and continue forward. Whether or not you need the online redo for a PIT recovery depends on how far forward you need to recover.
But you should take every precaution to prevent loss of online redo logs .. starting with having multiple members in each redo group ... and keeping those multiple members on physically separate disks.

"Fatal error, run database recovery " when there are no txns to recover.

Hi, all.
I have a DB file containing multiple databases. Without using DBEnvironments, I can open it to get the dbnames. I can open the databases RDONLY,
and see that their contents are correct. I can open them RW, and everything works.
But when I try to create a new one, I get this:
D = bsddb3.db.DB()
D.open('test.db',dbname='test',dbtype=B.DB_BTREE,flags=B.DB_CREATE)Traceback (most recent call last):
File "<stdin>", line 1, in <module>
bsddb3.db.DBRunRecoveryError: (-30974, 'DB_RUNRECOVERY: Fatal error, run database recovery -- PANIC: fatal region error detected; run recovery')
Note that this is in the non-transactional case. There is no Env, and there are no logfiles or __db files. So the error code mystifies me.
Strace shows that the file is opened RW, and read through.
B.DB_VERSION_STRING'Berkeley DB 4.8.24: (August 14, 2009)'
>>>
So, where to proceed? Many thanks for any and all help.

Hmm. Other thing to note:
[tradedesk@vader 2010-05-06.test]$ /usr/local/BerkeleyDB.4.8/bin/db_verify foo.db
db_verify: Subdatabase entry references page 266 of invalid type 13
db_verify: Page 0: non-invalid page 40 on free list
db_verify: trading.db: DB_VERIFY_BAD: Database verification failed
Not sure how that came about or how to prevent it, but it might have to do wit this issue.

Questions About Database Recovery (-30975)

Hello,
In Berkeley 4.5.20, we are seeing the following error sporadically, but more frequently than we'd like (which is, to say, not at all): "BerkeleyDbErrno=-30975 - DbEnv::open: DB_RUNRECOVERY: Fatal error, run database recovery"
This exception is being thrown mostly, if not exclusively, during the environment open call. Still investigating.
I will post my environment below, but first some questions.
1. How often should a database become become corrupt?
2. What are the causes of this corruption? Can they be caused by "chance?" (I.e. app is properly coded.) Can they be caused by improper coding? If so, is there a list of common things to check?
3. Does Oracle expect application developers to create their own recovery handlers, especially for apps that require 100% uptime? E.g. using DB_ENV->set_event_notify or filtering on DB_RUNRECOVERY.
Our environment:
Windows Server 2003 SP2
Berkeley DB 4.5.20
set_verbose(DB_VERB_WAITSFOR, 1);
set_cachesize(0, 65536 * 1024, 1);

set_timeout(60000000, DB_SET_TXN_TIMEOUT);
set_tx_max(100000);
set_flags(DB_TXN_NOSYNC, 1);
set_flags(DB_LOG_AUTOREMOVE, 1);
set_lk_max_lockers(10000);
set_lk_max_locks(10000);
set_lk_max_objects(10000);
open(sPath, DB_CREATE | DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_THREAD | DB_INIT_TXN | DB_RECOVER, 0);
set_pagesize (4096);
u_int32_t dbOpenFlags = DB_CREATE | DB_AUTO_COMMIT;
pDbPrimary->open(NULL, strFile, NULL, DB_HASH, dbOpenFlags, 0);
We also have a number of secondary databases.
One additional piece of information that might be relevant is that the databases where this happens (we have 8 in total managed by our process,) seem to be the two specific databases that at times aren't opened until well after the process is up and running due to the nature of their data. This is to say that 6 of the other databases are normally opened during startup of our service. We are still investigating this to see if this is consistently true.

Here is the output from the error logs (we didn't have this properly set up until now) when this error opening the environment happens:
12/17/2007 17:18:12 (e64/518) 1024: Berkeley Error: CDbBerkeley MapViewOfFile: Not enough storage is available to process this command.

The last line is generated by a DbException and was all we were seeing up until now.
I also set_verbose(DB_VERB_RECOVERY, 1) and set_msgcall to the same log file. We get verbose messages on the 1st 7 database files that open successfully, but none from the last one, I assume because they output to set_errcall instead.
There is 67GB of free space on this disk by the way, so not sure what "Not enough space" means.
Thanks again for your help.

Database performance issue (8.1.7.0)

Hi,
We are having tablespace "payin" in our database (8.1.7.0) .
This tablespace is the main Tablespace of our database which is dictionary managed and heavily accessed by the user SQL statements.
Now we are facing the database performance issue during the peak time (i.e. at the month end) when no. of users use to run the no. of large reports.
We have also increased the SGA sufficiently on the basis of RAM size.
This tablespace is heavily accessed for the reports.
Now my question is,
Is this performance issue is because the tablespace is "dictionary managed" instead of locally managed ?
because when i monitor the different sessions through OEM, the no. of hard parses is more for the connected users.
Actually the hard parses should be less.
In oracle 8.1.7.0 Can we convert dictionary managed tablespace to locally managed tablespace ?
by doing so will the problem will get somewhat resolve ? will it reduce the overhead on the dictionary tables and on the shared memory ?
If yes then how what is procedure to convert the tablespace from dictionary to locally managed ?
With Regards

If your end users are just running reports against this tablespace, I don't think that the tablespace management (LM/DM) matters here. You should be concerned more about the TEMP tablespace (for heavy sort operations) and your shared pool size (as you have seen hard parses go up).
As already stated, get statspack running and also try tracing user sessions with wait events. Might give you more clues.

Dear Christian,
yes, I solved this LOAD_SYSTAB problem.
This is what I did:
1. check XCMDOUT.LOG
2. However in my case, I did not see any clue there, so I read this link about LOAD_SYSTAB http://maxdb.sap.com/doc/7_7/45/11cbd6459d7201e10000000a155369/content.htm
I tried it manually, and it worked: dbmcli u2013d <DB_ID> u2013u DBMUser,password1 load_systab u2013u superdba,password2
From there, I know that I entered the wrong SYSADM User (superdba) password, this password was in my case the same one a SAPinst Master Password.
According to https://websmp130.sap-ag.de/sap(bD1kZSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=25591
a new installation of MaxDB database, by default, the credential for SYSADM is: "superdba,admin"
So, accordingly, the solution is:
change the SYSADM for the <DB_ID> in DBMGUI: D7D - Configuration - Database User area, exactly as the SAPinst Master Passwort.
Hope this helps.
Regards,
Mariana

Database recovery (online redolog ?)

hi all,
Been awhile since i touch on oracle db, i have been reading around and the emphasis for recovery is always on the backup and archivelog, but i think its wrong.
can i check ->
q1) for full database recovery, do i need the online redo log as well ?
q2) if the answer to q1) is yes, how do i duplicate online redo log to standby site ? (i don't think rsync will work as it cannot sure consistency in the redolog)
will oracle dataguard sync online redolog as well ?
q3) for archivelog, beside manual rsyncing, LOG_ARCHIVE_DEST_2 = 'SERVICE=standby1'
do i need the enterprise edition for the above ?
Regards,
Alan

q1) For a complete recovery, yes you need online redolog as well. Without online redolog,its still considered incomplete recovery since u lose data resides in online redolog
q2) You no need to synch online redo log manually. Once the backup is restored to the DR dataguard site and MRP process initiated, Oracle will synch online redolog/archivelog automatically based on protection mode specified
q3) Oracle dataguard applies to Enterprise Edition only. Without Enterprise Edition, we can configure log shipping (manual way).
Regards,
Ilan

Database consistency issue..

Hi.
SCCM 2012 English, RTM
For unknown reason the DR link broke between CA and primary.
It says Site Replication status both way Active, but data replication is mixed. Parent to child Global data - failed and child to parent site data failed. Child to parent global - Active. Replication link analyzer performs several checks and then informs
- Database consistency issues detected for site XXX. (parent). Skiping rule - shows different replication groups which are failed. I tried to replicate those, but nothing changed.(according to following article last step)
http://blogs.msdn.com/b/minfangl/archive/2012/05/16/tips-for-troubleshooting-sc-2012-configuration-manager-data-replication-service-drs.aspx
Any more ideas?

Now i have read more about DRS and SCCM 2012 and get in state where 2 from 3 replications are active.
Mainly with puting relevatnt pub files to RCM.BOX. But global data replication from CAs to PRI is still failed. No idea ....

DB_RUNRECOVERY: Fatal error, run database recovery

I am getting this error when trying to add data to QUEUE. But after I restart my app, this error does not happen anymore.
2009-08-16 10:27:12.558990 [ERR] mod_cdr_bdb.c:370 Unable to add cdr to Queue. Error=DB_RUNRECOVERY: Fatal error, run database recovery
Does anyone know what could be the cause of the error?

Hi,
Do you know the steps that lead up to this error? Can you reproduce it?
Were there any error messages sent to the error log file? Can you confirm that you have verbose error messages turned on by always initializing one of the error callback interfaces in your environment. This will provide verbose error messages:
DB_ENV->set_errcall, DB_ENV->set_errfile, DB_ENV->set_errpfx, and DB_ENV->set_verbose.
What flags are you using when opening the environment and the database?
The procedure you have to follow when you receive this error is described here: [DB_RUNRECOVERY|http://www.oracle.com/technology/documentation/berkeley-db/db/ref/program/errorret.html#DB_RUNRECOVERY]
DB_RUNRECOVERY:
There exists a class of errors that Berkeley DB considers fatal to an entire Berkeley DB environment. An example of this type of error is a corrupted database page. The only way to recover from these failures is to have all threads of control exit the Berkeley DB environment, run recovery of the environment, and re-enter Berkeley DB. (It is not strictly necessary that the processes exit, although that is the only way to recover system resources, such as file descriptors and memory, allocated by Berkeley DB.)
When this type of error is encountered, the error value DB_RUNRECOVERY is returned. This error can be returned by any Berkeley DB interface. Once DB_RUNRECOVERY is returned by any interface, it will be returned from all subsequent Berkeley DB calls made by any threads of control participating in the environment.
Applications can handle such fatal errors in one of two ways: first, by checking for DB_RUNRECOVERY as part of their normal Berkeley DB error return checking, similarly to DB_LOCK_DEADLOCK or any other error. Alternatively, applications can specify a fatal-error callback function using the DB_ENV->set_event_notify method. Applications with no cleanup processing of their own should simply exit from the callback function.Thanks,

Object Level Recovery or Whole Database recovery

I'm hoping someone may know how to advise me on the following;
On a datawarehouse db (10.2.0.1.0) a team member removed records from three tables, and I have since attempted flashback recovery without success. The database is in Archivelog mode, with Flashback enabled, but no Flashback logging enabled. The rows were removed on Friday afternoon (it is now Monday). I attempted to get flashback logging enabled by tagging the "Enable Flashback Database" tag in the Flash Recovery region of Recovery settings, and restarting the database. The database when restarted went into mount state, and subsequently on restarting (from mount - I did not dismount the db), it still has Flashback logging disabled. I attempted flashback again but the team member states the record stil arn't there. EM however had given the message 'The select tables...X X....have been flashed back'. However I can see also that Em says flashback logging is still disabled.
I now consider I might be better off to perform a 'Whole Database Recovery', as I simply want to get the tables recovered. I'm not sure if this will mean re-keying though. Can anyone advise? Thanks in advance. DW

The first step you should try is flashback query. Because using flashback query your database will remain intact, you don't lose anything from your database. Of course most likely it's too late for you now. Just for future reference.
Flashback database is only available after you configured Flash Recovery Area and turn it on. Sound like it's does apply here as well. Remember even you could successful flashback your database to the point before deletion, you will lost all data changes after that point. Flashback database only buy you sometime, because you don't need to restore datafile from backup.
The third option would be restore from your last backup, ( the latest one before deletion happen) and do incomplete restore to the point in time right before the incident.

Database Recovery Scripts

Does anyone have a set of database recovery scripts for various scenarios for 8i and 9i databases running on Windows 2000 and 2003?
Cheers,
Derek.

>>
We do a cold backup each night and have archive on. The scenarios are any that may occur i.e., media failure, dropped tables, lost control files etc.
>>
Hey Derek, the problem with cold backup is incase of media recovery required, you can't simply resotre the datafile/s which have/has problems. You need to restore complete database.
Its difficult to have incomplete reocvery or point-in-time recovery having cold backups.
I strongly recommend you start thinking about online backups. You need to assess your business requirements, and much you can efforts to loose?
