Crash When Trying To Clone Database
Jul 13, 2010
I have an Oracle 10.1 database on a Windows 32 bit platform that I am attempting to clone to a new server to make a development instance.
For this particular scenario the database needs to stay at version 10.1. Both servers are Windows Server 2003. Following oracle docs I have copied the home folder and am attempting to run OUI with the clone switch.
OUI crashes and reports the error as "unknown".
OUI also crashes if I try to run it without the clone switch from gui.
Why this occurs, and have confirmed that PATH is correct etc on the new dev server and the other obvious stuff.
I just need a quick way of getting this dev server instance up and running AND maintaining the same database version (10.1). I thought the clone operation would be a good option but don't know how to troubleshoot when the error is "unknown".

the db cannot startup after host crash.
the strange thing is "lkinstrdmetdev" is the wrong name(sid is rdmetdev), and the file does not exist in the FS too. the correct file name should be "lkrdmetdev" and i've deleted this file from the directory. I did not do any changes. and no any oralce processes running while i started up the oracle instance.

i am using 11.2.0.3 version of oracle. We have recently migrated to 11g, after 1 month of smooth and comparatively better performance, we are suddenly facing performance issues with our database and it got crashed twice within 5 days. even we didnt push any new code to our database in recent past, atleast after the 11G migration. And after getting feedback from the ORACLE corporation guys , they pointed out about the default database stats gathering job, which was eating most of the CPU, because of the default degree mentioned So it was running in 160 parallel threads causing resource starvation.so we reduce the degree of the stats gathering job to 8 .
But the database crashed again two days back, and rebooted within 3 mins to back to normal, even after this default degree changed to 8. This is happening due to any specific application related sql or anything else.

I want to create such a script to clone the Database user with the new name. Just like we do normal import and export I want that i should enter just the username of the existing user and username of the new user I want to get created, the password for the same.
It should create the new user with all roles and the default roles and privileges of old user.

I'm using Oracle Database 11g R2 for study purposes.Currently I'm learning about the DBCA clonic templates.I have an Oracle DB 11g R2 X86 running properly in Ms Windows XP Professional SP 3 X86, using DBCA I created the seed template file .dbc and the .CTL and .DBF files, later I copied those files to a server running Oracle DB 11g R2 X86 in Ms Windows 7 Ultimate X86. Again, using DBCA I successfully created the source database through the seed template file, everything was ok.
Now, I formatted my testing server and I installed Ms Windows 7 Ultimate X64 and Oracle Database 11g R2 X64. I copied the seed template file .dbc and the .CTL and .DBF files to "assistantsdbca emplates" directory. Well, I started DBCA to try create the source database and when the DBCA is creating and starting the Oracle instance it shows the errors:
ORA-00604: error occurred at recursive SQL Level 1
ORA-06553: PLS-801: Internal error [56327]
Is it possible to clone my testing DB from X86 to X64 using DBCA clonic templates?

1. 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.

There is a requirement to make a table data in a database (eg: HR database) available in another database (eg: EMP database), instead of accessing it using database link. In EMP database(where data needs to be cloned), data will only be queried and no write operation will be done. Data in remote database (eg: HR DATABASE) will be occassionally fully truncated and reinserted. The plan is to do a similar truncate and reinsert of data (from HR database) into EMP database monthly once using dbms scheduler job. So basically data in just one table needs to be cloned in another database.
Question: For this situation, is a regular table or Materialized view the right choice to clone the table in EMP database and why? The table in HR database (remote database) is not very big.

however the problem we have is when testing a third party supplied application we have evidence of data loss when we crash an instance in the RAC cluster, however this only occurs during approximately 30% of tests, our suspicion is that the application is managing the failover and reapplying only certain types of transaction, the problem is as we have to perform multiple tests to get a reproduction it is immensely time consuming and expensive to test this and the vendor has a tendency to report that the issue is fixed in a patch and then we reproduce the bug during testing.
For a session I can cause it to crash using the oradebug event e.g. alter session set events
'sql_trace[sql: 7h35uxf5uhmm1] RDBMS.crash(0)'
Support have advised that there is no way to cause an instance crash this way, so I am in the process of raising this as a feature request however I would be interested in how other people currently test how third party applications respond to RAC node failures, we currently use a script that executes a kill -STOP to pasue logwriter then sleeps for a short period of time before aborting the database instance, this at least allows us to force a failure during the commit so we are more likely but we can't guarantee that we have tested the exact type of transaction that is causing the problem.

Consider a situation:
There are two users 'A' and 'B'
account number of A: 001234
account number of B: 002678
Suppose, if A wants to transfer $1500 to B's account
update cust_acc
set balance = balance - 1500
where
account_no = '001234';
[code]....
Assume that, oracle crashes somewhere between first commit and second commit.In this case, A's total money is deducted by $1500..But $1500 is not yet transferred to B's account.How will oracle keep track of these information?

We have a report that is using a blob and in that blob is a text string that is in base64. The text string is converted into an image via a function that is a java class. The function works well when executed from SQL Developer, PL/SQL Developer, and other tools either good or bad image.
The problem is that in the reports it crash if the image is bad (no error message). In the report how do I make an exemption if the image is bad to just return null? This way the report does not crash.

I am cloning my prod db to test with the rman active clone command. I can successfully clone my DB, but after a few hours or so I see messages in the alert log that I have corrupted blocks in several datafiles. Note, i dont see these messages in my PROD DB therefore I think that DB has no corruption. I have few questions:
1) I was reading tha having tables or indexes set with the NOLOGGING option can cause objects to be unrecoverable. Would this affect my active clone?
2) I know you can either change a DB or tablespace to force logging. Is there a query I can use to determine if the DB is in force logging mode.
ALTER TABLESPACE tablespace_name FORCE LOGGING;
ALTER DATABASE FORCE LOGGING;
3) Lastly how to check as why my clone DB would have corrupted blocks.
Here is the clone command I am using.
rman catalog=rman/rman@proddb target=sys/sys@proddb << EOT
connect auxiliary sys/sys@clonedb
duplicate target database to clonedb from active database nofilenamecheck
pfile=/u01/app/oracle/product/11g/dbs/initclonedb.ora ;
exit

I'd like to confirm whether its possible to clone a database instance from a RAC cluster to a single server, with an additional issue that the RAC cluster is running Oracle 10g and the single server is running 11g. Can I do that directly or do I need an intermediate step to upgrade the database instace to 11g? Or can I even use exp/imp on RAC?

My management is asking me to find the best way to migrate our 3.3 TB data warehouse to a new server. I currently use RMAN to back up the database. This is done offline on Sundays, and it takes about 9 hours, compressed backups to disk. Archived log backups are done online, not in conjuction with the db backup.
I have read a number of documents detailing step to use OEM Db Control (aka dbconsole) to clone the database to the new server.
I have a few questions:
1. I need to clone the Oracle SW first, as our current install has patches, so it should take less time.
2. Do you think just restoring from the last RMAN backup and doing recovery would be faster than cloning?
3. On the new server, I have assumed that the root user (not me) would have to pre-create the OFA structure, e.g.; we have some mount points like /f01/oracle/DBNAME or /g01/oracle/DBNAME. I cannot imagine that the Db control Gui or Rman could create that structure on the target server. Is that correct?
4. There seems to be an attitude in my shop that the storage array mount points and OFA would not have to be identical on the target server. Any opinions?
Back in 1995, I successfully manually cloned a database to a new server in an HP environment, but it was only about 70G!!

I am looking to create a DDL-only clone of a 2TB database. The purpose of this clone is to provide developers a preprod-like environment where they can test the syntax of their code changes before deploying to production. The database will reside on a seperate, small server.
As I only need the structure of the objects and not the data, my first port of call was EXP using rows=n. However, when I IMP to an indexfile I see that the initial extents have been defined on the tables (in some cases 1GB!). As stated my clone environment is small, so I would be looking to have these set at 1mb. how I can achieve this? I will want to be able to automate the cloning of the database as much as possible. Perhaps there's some other way other than EXP/IMP?
