Can we put RAC database in Archivelog mode without shutting down

All,
Can we put RAC database in Archivelog mode without shutting down.
Currently our new production database (2 node RAC) is in no archive log mode, Need to enable archive log in the database...
I believe we need to set the cluster_database=false and then put the DB in archive log mode then we need to bounce the database to take effect...
Just curious to know in 11gR2 ...Can we put the RAC database in archive log mode without any downtime ...?

Even RAC or non-RAC, database should bounced and enable/disable archive log mode from mount status.

Another RMAN duplicate problem - RAC database to single instance

Hi,
I have a problem with the RMAN duplicate procedure and was hoping someone can help.
I would like to create a duplicate of our production RAC database on a separate, stand-alone, database server on another site. This duplicate will be used for intensive querying by another business unit who I don't want to have access to our production database.
My procedure goes like this:
1. Create a disk (not ASM) based backup of the datafiles and any archived redo logs:
"run {
allocate channel d1 type disk;
backup format '/u02/stage/df_t%t_s%s_p%p' database plus archivelog delete input;
release channel d1;
2. Tar and scp these files to the same location on the stand-alone database server.
3. In the meantime, work has been happening on the production database and further archived redo logs have been generated. I don't really care about these logs for the purposes of the duplicate however, I just want to duplicate to the point of the recent backup. To do this, I run the following SQL to determine the sequence number that I should be duplicating up to:
"select max(sequence#), thread# from v$archived_log where deleted='YES' group by thread#;"
4. Duplicate the production database to the stand-alone database (all the SQL Net stuff is working).
"run {
set until sequence (value returned by above SQL statement);
duplicate target database to XXX;
However, my problem arises because I don't know how to handle the fact that there are two threads. I understand that each thread relates to one of the RAC instances, I just don't know which one to specify for the duplicate. We have a database service which the client application connects through, and that service runs on on or other of the instances. Should I just care about the logs from the instance where the service is currently running?
Am I even approaching this is the correct way?
I look forward to any help that people may be able to offer.
Regards,
Phil

Hi Werner,
Thanks again for your help, there is still something wrong though. "list backup of archivelog all;" shows:

you can see that something is setting the recovery SCN to 569505448 which higher even then any of the archived logs mentioned above. If I select current_scn from the production database, this gives me 569528258 which is closer to the value which RMAN is expecting to recover to than any of the archived redo logs.
Can you think what might be causing RMAN to try to recover to this value? and why does it appear to be ignoring the SET UNTIL SEQUENCE command?
Cheers,

Arivelog mode configuration proble in RAC database

Hi,
I'm trying to configure RAC database in archivelog mode but when try to do so get the following error, during the database startup in mount state
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.1.0/db_1/dbs/initorcl.ora'
This error shows that the system could not find the initorcl.ora and really it does not exist. But the system at this stage is single
instance as I chenged the value of cluster_database=false before shutdown and then start.
when I enter the command startup mount it give me this error. What should I do to avoid it. Should I make a pfile of this from spfile in cluster mode
and then put this pfile in the desired path to start the single instance or any other thing should I tried.
Regards,
Abbasi

Perform the following steps to relocate the SPFILE from the local file system to an ASM disk group.
    * Create a text-based initialization parameter file from the current binary SPFILE located on the local file system:
      SQL> CREATE PFILE='$ORACLE_HOME/dbs/initTESTDB.ora'
        2 FROM SPFILE='$ORACLE_HOME/dbs/spfileTESTDB.ora';
      File created.
    * Create new SPFILE in an ASM disk group:
      SQL> CREATE SPFILE='+TESTDB_DATA1/TESTDB/spfileTESTDB.ora'
        2 FROM PFILE='$ORACLE_HOME/dbs/initTESTDB.ora';
      File created.
    * Shutdown the Oracle database:
      SQL> SHUTDOWN IMMEDIATE
      Database closed.
      Database dismounted.
      ORACLE instance shut down.
    * Update the text-based init<SID>.ora file with the new location of the SPFILE in ASM:
      $ echo "SPFILE='+TESTDB_DATA1/TESTDB/spfileTESTDB.ora'" > $ORACLE_HOME/dbs/initTESTDB.ora
    * Remove (actually rename) the old SPFILE on the local file system so that the new text-based init<SID>.ora will be used:
      $ mv $ORACLE_HOME/dbs/spfileTESTDB.ora $ORACLE_HOME/dbs/BACKUP_ASM.spfileTESTDB.ora
    * Open the Oracle database using the new SPFILE:

RMAN backup in ORACLE RAC database

Hi there,
We are using RMAN backup strategy for taking backups from one node(eg.node1).Database is RAC database, version 9.2.3. and OS is Solaris 5.10.
this is the configuration which we use, as follows:
Connecting to Prod.Database using catalog database.
rman catalog=rman/rman@CATDB target=sys/oracle@PRODDB(node 2).
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 30;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanback/_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 5;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/CMWPROD_%s.bak';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'SYS/oracle@PRODDB(node2)';
CONFIGURE MAXSETSIZE TO 7 G;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/9.2.3/dbs/snapcf_CMWPROD1.f';
As the above config shows RMAN is connecting to PROD DB (node 2). But we need to take backups (datafiles and as well as archive logs) from two nodes (i.e from node 1 and as well as node 2).
Is there any possibility for taking backups from two nodes?
Thanks,
Balu.

How simulate massive archivelog generation

Hi,
We're in the process of testing our physical standby database, if the network link would be able to cope with peak load and archivelog generation during this time.
I'm looking for some sample script to run to simulate massive archivelog generation, mayb 1GB every minute. We're on 11.2.0.1 version.
The database is currently empty, no load , no data.

dulaJust write a little PL/SQL procedure with a loop that iterates 10 million times, and inside the loop do a little dml - insert or update.
Pseudo code:
for i = 1 to 10000000
insert into testtable ('hello world');
next iThe above is not valid pl/sql, but demonstrates the process. I leave it to the student to pull out the PL/SQL manual found a tahiti.oracle.com and work out the exact syntax. If you don't have space to grow testtable by 10,000,000 rows, use an update instead. It will still generate the necessary redo.

Archivelogs deleted in RAC ASM Production for standby

Hi,
DB: 10.2.0.4
OS: AIX 5.3 L
This is 2 node RAC ASM database with single standby on ASM.
I set the retention policy to 2 days for my Live database.While running the TAPE backup script, the archivelogs were deleted .The deleted archivelogs are generated just before /while the TAPE backup.Backup script has not considered the retention policy for Primary.All archivelogs , except generated after backup ,were deleted .
Now my standby is waiting for deleted archivelogs.
How do i can make sync of my standby with Primary ?.
Please understand my position and request you to help me on this.
Regards,
Sunand

Hi Jean & Abhi,
Thanks you very much for your reply.
I came out the problem with following taking the backup of incremental from standby SCN value.
Actually i did not have backup of deleted archivelog .Now my standby database is in sync with primary and working fine.
About recovering of deleted archivelog from backup piece, If i run below script , whether it will recover the specified archivelogs to our archivelog destination or will recover to database ?.I never done this before.Could you explain me ,please.
run
allocate channel t1 type sbt.....;
restore archivelog from sequence X until sequence Y thread 1;
Also, my database is on ASM. Once we recover the archivelogs,how do i can move to standby?.I mean , moving them from ASM to file system and registering to standby database .
Thank you very much,
Regards,
Sunand

Backup Exec 12.5 and Rac database

We always use rman to backup and restore our rac database without problems but now we would like to try with Backup Exec 12.5. Yesterday we installed the server for backup exec and the oracle agent for linux and by the way we did a full backup of our Rac database. The problems was when we tried to restore it. When we restore a single database it work but when we try with RAC it does not work.
Questions:
Is there a different agent for oracle Rac database or it is the same?
Are there aditional steps to configure the agent for Rac database?
I really appreciate your help.

++We are using flash recovery area and all archive logs, flash back logs and backup sets go in there?The system administrator wants to back up the full directory of flash recovery area. Would that be enough?Is a backup of oracle home is needed?+
Normally there is no need to take oracle backup home , if yours FRA contain baskupset for database files (controlfile,db files),archivelogs ,flashback logs.You should also consider the pfile if you are not using spfile,spfile itself contain in RMAN backupsets.
Consider yours oracle binary backup (i.e cold backup) before any maintainance (patching activity).
Read http://oraware.blogspot.com/2008/07/fra-capacity-planning.html
Are there any backup settings required before backing up files while the database is on, like setting them in backup mode or etc?
yes for online database should be in archivelog mode,if you are using RMAN then there is no any setting required before backup , using RMAN you just have to connect with target database and start online backup using yours own backup script.
Any documentation discussing the backup steps, and what needs to be backed up will be appreciated

Hi,
Some tweaks for your script.
echo "Shutdown Database";date
srvctl stop database -d PROD
srvctl status database -d PROD
echo "Database shutdown on";date
echo "Mount Database ";date
srvctl start instance -d PROD -i "PROD1" -o mount1. If you database does not shutdown properly , does your script stops the execution of next step?
2. configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '/BACKUP/PRODBKP/%F';(Why you need to configure this every time) ?
It's persistent at db level one time setting (until some other script changes the settings by other dba - else remove that - set the configuration at db level once for all)

RMAN configuration in ORACLE RAC database

Hi there,
We are using RMAN backup strategy for taking backups from one node(eg.node1).Database is RAC database, version 9.2.3. and OS is Solaris 5.10.
this is the configuration which we use, as follows:
Connecting to Prod.Database using catalog database.
rman catalog=rman/rman@CATDB target=sys/oracle@PRODDB(node 2).
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 30;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanback/_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 5;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/CMWPROD_%s.bak';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'SYS/oracle@PRODDB(node2)';
CONFIGURE MAXSETSIZE TO 7 G;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/9.2.3/dbs/snapcf_CMWPROD1.f';
As the above config shows RMAN is connecting to PROD DB (node 2). But we need to take backups (datafiles and as well as archive logs) from two nodes (i.e from node 1 and as well as node 2).
Is there any possibility for taking backups from two nodes?
Thanks,
Balu.

You will need to setup an NFS share such that both nodes can access each other's archived redo logs area. You also need to ensure your LOG_ARCHIVE_DEST_n parameter settings are properly set. Once setup correctly, either node will be able to run the backup and include each other's archived redo log files. Since this is RAC, the data files are shared by design and either node can already backup these files.
Multiple channels would allow 'simultaneous' backup of the archived redo logs.
I would highly recommend using a CFS (single shared file system where all nodes store their archived redo logs distinguished by thread) to store the archived redo logs, this reduces administration and configuration especially when you get ready to scale.
Hope this helps.

Unable to startup 12c RAC database, can't open spfile in ASM

hello,
I'm testing 12cRAC database on RHEL5 and need your help to troubleshoot and fix the following issue -
DBCA fails at the end of the configuration to create and startup new RAC database with the following errors
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/TDB1/spfileTDB1.ora'
ORA-17503: ksfdopn:2 Failed to open file +DATA/TDB1/spfileTDB1.ora
ORA-15056: additional error message
ORA-17503: ksfdopn:2 Failed to open file +DATA/TDB1/spfiletdb1.ora
ORA-01017: invalid username/password; logon denied
I also tried executing script (which was created by DBCA) to create the new DB manually and got the same results - it happens during first attempt to start it up using SPFILE after new DB was successfully created (it was started up using pfile)
Clusterware with ASM install was successful, binaries were also installed without issues,
cluster seems healthy, I see correct files within ASM using asmcmd etc ..
got stuck here and need some directions ... very confused by ORA-01017 password error
wonder if anyone had same or similar issues ?
Thank you !

Fixed.
Thank you everyone for suggestions and recommendations -
ASM is accessible using asmcmd and I can see all the DB files incuding spfile, they were created by DBCA, alert log showed same information I posted
After extensive troubleshooting and testing the issue was idedntified and fixed - 'dba' group needs to be the primary group for 'oracle' user, not the secondary one. I suspected that something was not right with 'oracle' user access to asm based on that strange password error. There is more I need to check as the issue and fix with swapping groups seems strange. Secondary group is not enough ti have proper rights ??? my first reaction was - seriously ? wtf ?
Anyway - I need to move one now ...
Thank you again !

How can I have a collective AWR report for RAC database in 10gR2 and 11gR1?

Plz correct me here
awrrpt.sql takes the snapshot at the instance level and incase we have 5 instances we have to take 5 awr reports for a particular period.correct???
If above is true ,any wayout to collect a single collective AWR report for RAC database which includes information on all the instances in Oracle 10g R2 or 11gR1 ?
Thanks in advance
Gagan

I have never come across a way for this. though I can n't say it is not there.
But I guess it may not be feasible too becuase as we know the current AWR report contains data which is specific for one instance.
Various hit ratios, top events, instance effeciency reports.... what not ..
It would be really nice to see something is a new format where it lists values from each instance in a single report.. I guess such a thing Does not exiist as of now.

Question about DBCA generate script o create RAC database 2 node cluster

Question about creating two node RAC database 11g after installing and configuration 11g clusterware. I've used DBCA to generate script to create a rac database. I've set
environment variable ORACLE_SID=RAC and the creating script creates instance of RAC1 and RAC2. My understanding is that each node will represent a node, however there should only be one database with a name of 'RAC'. Please advise

You are getting your terminology mixed up.
You only have one database. Take a look, there are one set of datafiles on shared storage.
You have 2 instances which are accessing one database.
Database name is RAC. Instance names are RAC1, RAC2, etc, etc.
Also, if you look at the listener configuration and if your tnsnames is setup properly then connecting to RAC will connect you to either one of the instances wheras connecting to RAC1 will connect you to that instance.
