Cloning the Oracle Database Server which has Grid 11.2.03 and DB 11.2.0.3

Hi DBA's,
Did anybody came across cloning a database servers? If i have the OFA for Grid and DB homes i.e /u01/app/oracle so after clone it will be the same across all servers. So the inventory structure will be same also. After cloning changing the listener.ora files to point to new IP/Hostname can bring up the listener. What else? Did anybody tried this things and what all issues have come or what all issues could come.
Thanks,
Bhushan Altekar

Ok. I got the cloned VM . I did the same steps as we use for normal grid and db cloning. Below are the steps i did.
1) change the ip address
2) reboot
3) after reboot wait for few minutes till the ASM comes up automatically
4) as root run the below command
/u01/app/oracle/product/11203/grid/crs/install/roothas.pl -deconfig –force
5) Change the hostname with system-config-network-tui - Edit DNS Configuration and change the hostname here
6) Edit the /etc/hosts file and enter the ip address and the hostname
7)Reboot
8) After the reboot as root run the command
/u01/app/oracle/product/11203/grid/root.sh
================================
#output of step 8
[root@cat ~]# /u01/app/oracle/product/11203/grid/root.sh

===============================
9) stop the HAS service
crsctl stop has
10) Add the listener
srvctl add listener
11) Add the asm instance as new cloned grid don’t know about it. So we have to add it and see its added or not.
12) srvctl add asm -d '/dev/oracleasm/disks/*' # Note here if you specify wrong diskstring. Your Oracle restart stack wont come up automatically after reboot. so please specify it correctly.
13) crsctl status res # check all the resources are added or not
14) edit the listener.ora file and change the hostname ( HOST = XXXX part of the file)
15) crsctl enable has
Congrats we have successfully cloned the database server itself.
Please check the steps i did. And add if you think it should be added and taken care of.
Thanks,
Bhushan Altekar

Nice day to you too. :)

What is the exact difference between Database Cloning and Database Refresh?

Hi,
Can anybody tel me the exact difference between Database Cloning and Database Refresh?
I Have some conflicts in these topics.
Thanks
Rajesh

Refresh is what it says, "refresh" . You have a main site which would always have the data being inserted into it. There would be another site which would remain some where else . This site needs to be refreshed with the primary site. So you need to do export from the primary, push it to the secondary site and done!

Weird issue occurring after cloning the R12 Vision instance.

Hi everyone,
We are currently evaluating R12 using the Vision DB instance. Since I'm seeing that the apps processes like to have at least 2gb of memory, the initial server just isn't beefy enough for R12 so I cloned it over to a better server following metalink Note:406982.1 (Cloning Oracle Applications Release 12 with Rapid Clone)
There were various cloning issues that came up that fortunately, I was able to resolve myself .. still with tarring up directories, ftp'ing the tar files, etc etc it took almost 2 days to finish the clone.
Upon starting the clone I'm seeing the following errors reported when the db listener and the apps fndfs listener start:
TNS-01114: LSNRCTL could not perform local OS authentication with the listener
TNS-01115: OS error 22 creating shared memory segment of 129 bytes with key 2044160132
However, the listener processes actually do start even though the above errors are reported and I verify that I can see the server processes for both. In addition, I can login to apps and do everything without any issues and login from sqlplus to the database remotely and everything appears to be working.
But if I try to look at the listener status or try to stop either listener process I get the above errors. So, if I need to bounce the app or the db I have to actually kill the listener processes in order to do so. Then upon startup, the above situation repeats.
So, I've opened a SR in regards to this as it appears to be a cloning bug. The only metalink hits I found were talking about the shmsys:shminfo_shmmni setting (currently at 200) but I don't think that's it since I've had 6 apps instances up and running on this particular server before.
Currently the R12 Vision instance is running with RUP 1 applied. I did see there was a new Techstack update and a new RUP 2 update for apps released just last week but thought I would ask if anyone else who's used rapid clone with R12 experienced similiar issue?
Thanks.

I think your perl version is a little low for R12. Here is what I have in an upgraded R12 from 11.5.10.2 Vision:

Entity Bean Rollback fails: caches are out of synch with the database

We are encountering a critical issue where the rollback of a session transaction rolls back any database changes, but doesn't roll back bean changes in memory. When we next access the bean, it returns information that should have been rolled back. The memory cache is out of synch with the database.
We have a simple session bean S, using container managed transactions. We also have an entity bean E using bean managed persistence. E has a single member <name>.
We implement a method s() in S with <trans-attribute> Required as follows:
public void s() {
Context lookupContext = getLookupContext();
SHome shome = (SHome) lookupContext.lookup(SHome.NAME);
S s = shome.findByPrimaryKey(thePrimaryKey);
System.out.println("-- current name = " + s.getName());
s.setName("IGNORE");
EJBContext ejbContext = (EJBContext) getContext();
ejbContext.setRollbackOnly();
Since this is BMP, the setName call issues our SQL update against the S record. When the session transaction rolls back, the database changes are also rolled back. But the entity bean in memory shows the modified name. We can see this in the next call to s() since the getName() returns IGNORE rather than the original value. We have also gotten debugged into the underlying instance cache associated with the S bean descriptor. I.e.
AbstractEJBHome ejbHome = (AbstractEJBHome) lookupContext.lookup(SHome.NAME);
AlternateHashTable aht = ejbHome.getBeanDescriptor().getCache();
Looking at this map of bean instances also shows that the bean instance for S is not rolled back.
From previous conversations with the server technologies team, we understand that during the transaction, we should be working on a cloned copy of the S bean. Upon rollback, the copies should be discarded rather than merged back to the cached bean. They seem to be merged regardless of rollback state.
We are using OC4J 10.1.3.0.0 (build 060119.1546.05277).

Actually, what one or the developers in my group found out is two things:
1) The clone is a shallow copy.They copy the references but not objects themselves. This has been causing problems for us.
2) It seems that you don't work on a copy and you work on the original and they keep a copy. Now, this is fine IF you don't have multiple threads working on the same Entity bean and we moved our application from Weblogic where it throws an exception if that Entity bean is in use to OC4J which is suppose to copy the bean and doesn't so you have multiple threads possibly modifying the same object.

Hello Tawfik,
You can use RMAN duplicate with the following link for 9i.

How to refresh the database

Hello All
I would like to know how to reresh the database after cloning or before cloning.
Krish...

You mean, you like to syncronise both the databases , then, in my opinion, there is one option left to create standby database , however, if you want to syncronise only a part of your database , for example , table's kinds of stuffs , then there is MV's and if you want to replicate on different databases , then there is streams to use.

Cloning Oracle database 8.1.7.0

Hi,
We have upgraded our database from Oracle 8.1.7.0 to Oracle 8.1.7.4 , applied terminal patch set(Oracle 8.1.7.4) , as we have to upgrade it further to 10g rel2.
After upgrading to 8.1.7.4, we required to apply the database fixes against the mentioned bugs.
One of the Serious Server Issues is mentioned below after upgradation,
Changing the Database Character Set can corrupt LOBs ( Note 118242.1)
we have gone through the note mentioned above,
In that one of the point regarding cloning is as below :
If the database version is 8.1.7.3 or 8.1.7.4:
- install non-patched Oracle 8.1.7.0.0 from the original CD-Pack
into a separate ORACLE_HOME
- take a full backup of the database
- create a clone database from this backup using the 8.1.7.0.0
version of the RDBMS software -- contact Oracle Support
if you need help; the clone should open with the older
non-patched software without any downgrade steps
- export all non-system tables with non-NULL CLOB and/or NCLOB columns
from the clone; do not forget to set NLS_LANG environment
variable to the database character set for the export session;
you can use the 8.1.7.0.0 version of the Export utility
- truncate the exported tables but in the original database
- reimport the exported tables into the original database;
do not forget to set NLS_LANG environment variable to
the database character set for the import session;
use the Import utility from the original ORACLE_HOME
- drop the clone database - do not use the clone for other
purposes as it is not supported to run a patched database
with the non-patched software.
How to Clone the Oracle database (8.1.7.0) on windows OS ?
From where i would get the Cloning steps to accomplish the above steps on Windows OS ?

Cloning A Database In Oracle 11g

Hi All,
I am cloning a database from one server to other server. I am using oracle 11g version:-
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE 11.2.0.1.0 Production
TNS for Solaris: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
I am new to DBA and I need your help to perform this. I have done a installation of a database but cloning I am doing for the first time. The database size which I want to clone is of 6GB, so i won't think it will take much time to clone the database.
While checking in google I come to know that the same thing can be performed by RMAN. Can anyone of you suggest me how to do this activity step by step.
If you can share any links where I can see all of the steps it will be helpful.
Thanks in advance.

I am new to DBA Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to tahiti.oracle.com.
Drill down to your product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.
Give a man a fish and he eats for a day. Teach a man to fish and he eats for a lifetime.
and I need your help to perform this. I have done a installation of a database but cloning I am doing for the first time. The database size which I want to clone is of 6GB, so i won't think it will take much time to clone the database.

If you can share any links where I can see all of the steps it will be helpful.
In the above library, look for "Backup and Recovery User's Guide"

Cloning a Database (and ORACLE_HOME

I want to make a total copy of a database and its ORACLE_HOME. To me, this looks like a two step process:
1) Clone the ORACLE_HOME. I completed this successfuly using GC (10.1.0.4)
2) Clone the database using that cloned ORACLE_HOME. This doesn't appear to work as the cloned ORACLE_HOME from #1 doesn't appear in the available ORACLE_HOME options. I did manually add entries in /etc/oratab and the oraInventory inventory.xml file (and bounced the agent) and still my ORACLE_HOME doesn't appear.
There also appears to be a way to add an ORACLE_HOME manually -- as it really isn't a database.

Hello,
I’m not a trained DBA, and hardly have Patrick’s experience, and although he makes perfect sense, the following are three threads about cloning APEX, and none of them have a (reported) good ending:
Post Clone Apex steps
Blank screen after cloning database
After Cloning from Production Apex Doesnt Work
Maybe things are not that simple and straightforward, and the accumulated experience at Oracle Support suggests that what seems to be the long and hard way is actually the short and easy one. So, unless Patrick tells you that he has done/witness it himself (and as a member of the APEX development team, it’s highly possible), I would go with Oracle Support.
Just my 2¢.

Arie.

Moving the database to different mount point.

Hi,
I have R12 app tier on one server and 10gR2 database on separate server.
I want to move the database files from /u01/oradata/PROD to /u02/oradata/PROD on the same server.
I know how to do this for the database using alter database rename file .....
But what do I have to do with the application and context files.?
Do I just need to edit the values s_dbhome1, s_dbhome2, s_dbhome3 and s_dbhome4 to point to /u02/oradata/PROD and then run adconfig?
Many thanks
Skulls.

I am not cloning, just moving the databaseI know, but Rapid Clone does also help (use the same hostname, domain name, port pool, ..etc except for the directory paths) -- Please note you do not need to use "alter database rename file" as Rapid Clone will take care of that.
so I think manual changing datfile names is needed, followed by edit context file and run autoconfig?This is also valid.
Thanks,
Hussein
