Cloning Multi Node To Single Node

This document briefly outlines the procedure for cloning an 11i multi node instance to a single node instance.

Assumptions
1. SOURCE Instance is split on 2 NODES:
SOURCE DB NODE – Both APPS and DB services installed on 1st Server
Application tier services are shut down
SOURCE APPS NODE – Both APPS and DB services installed on 2nd Server
Application tier services are started
2. TARGET instance is to be a single node (may be a new machine or one of the above)

Summary

Shut down the apps server
Start all services on db server
Run autoconfig to convert to instance to a single node
Run the preclone perl scripts
Copy files to new location
Convert source to 2 nodes by running autoconfig
Run clone scripts on Target

Cloning SOURCE Instance

1. Refer to the latest version of the cloning documentation on Metalink (Metalink Doc ID: 230672.1) to determine which patches to apply before cloning.

2. Shutdown the application server by running the adstpall.sh script:
cd /oraprod/oracle/prodcomn/admin/scripts/PROD_finsvr/
./adstpall.sh apps/apps

Log off source APPS node
Log on source DB node

Make multi node a single node to begin cloning.
1. cd /oraprod/oracle/prodcomn/admin/scripts/PROD_finsvr

2. Start all application services on database Source DB Node using adstrtal.sh:
cd /oraprod/oracle/prodcomn/admin/scripts/PROD_finsvr
./adstrtal.sh apps/apps

Even though the listener and concurrent manager are the only services started on PROD, you will need to ensure that you start ALL services. Verify that the Concurrent Manager is up.

3. Run autoconfig:
cd /oraprod/oracle/prodcomn/admin/scripts/PROD_finsvr
./adautocfg.sh

Read prompt carefully, choosing default responses where possible.

Migrating to AutoConfig on the Source DB Node (necessary only if a new rapid clone patch is applied).

4. cd /oraprod/oracle/prodappl/ad/11.5.0/bin (that is, $AD_TOP/bin)

Create appsutil.zip file:
perl admkappsutil.pl

appsutil.zip created in $APPL_TOP/admin/out

On the database tier (finmgr), copy or FTP the appsutil.zip file to the RDBMS_ORACLE_HOME.

5. Copy file appsutil.zip to /oraprod/oracle/proddb/9.2.0/*
unzip -o appsutil.zip

Generate and Apply AutoConfig Configuration files
This step performs the conversion to AutoConfig. Once completed, the previous configuration will not be available. The database server and the database listener must remain available during the AutoConfig run. All other database tier services should be shut down.

Warning: Running AutoConfig on the database node will update the RDBMS network listener file. Save the listener file before you run autoconfig.

7. Change directory to RDBMS_ORACLE_HOME/appsutil/bin
cd /oraprod/oracle/proddb/9.2.0/appsutil/bin

adconfig.sh contextfile=PROD_finmgr.xml appspass=apps*

8. Prepare the source system database tier for cloning
cd /oraprod/oracle/proddb/9.2.0/appsutil/scripts/PROD_finmgr (that is, $RBDMS_ORACLE_HOME/appsutil/scripts/$CONTEXT_NAME
perl adpreclone.pl db Tier

9. Prepare the source system application tier for cloning
cd /oraprod/oracle/prodcomn/admin/scripts/PROD_finmgr (that is, $COMMON_TOP/admin/scripts/$CONTEXT_NAME)
perl adpreclone appsTier

10. Stop all services (DB and APPS)
cd /oraprod/oracle/prodcomn/admin/scripts/PROD_finmgr/
./adstpall.sh apps/apps
Shutdown database listener (addlnctl.sh stop apps/apps)
Shutdown database (addbctl.sh stop apps/apps)
Or run the stopDB script in /oraprod/scripts (doing so will attempt to shut the services again)

11. Copy files
Create the respective folders on target node:
clondb
clondata
clonora
clonappl
cloncomn

Copy the files from Source DB Node to Target Node. As root user, mount source node on target Node by editing /etc/exports on target node and adding the line where the source files are located (i.e. /oraprod/oracle).

Then restart NFS on the target server by entering the following command at the command prompt (as root user):
service nfs restart

12. On the target node (that is, where the clone is being created), do the following:
a. su – applmgr
b. cd /orapatch (new clone top directory)
c. mkdir prodfiles (where we want the files copied to)
d. su – root
e. Mount SOURCE directory onto TARGET directory
f. Copy the files using the operating system utilities

May need to ensure that the owner name and group of target directories are applmgr and dba respectively and not nfsmount.

To convert from single node to multi node:

Run autoconfig on Source Apps Node to make Source Instance 2 Node.

When a report is run on the target instance we get an error: “File server could not verify its initialization parameters when viewing output”. Patch 4244610 was applied, but this did not resolve the issue.

Removed spaces from listener.ora file in /orapatch/oracle/clonora/8.0.6/network/admin/clon_newtest/listener.ora. Removed all spaces near the APPLFSTT parameter. Removed everything and left reference to database alone. Bounce listener.

To change color and name, go to SysAdmin/ Security/Profile/System, under profile %Site%, change Site Name to new name. To change color, navigate to profile %Color% JavaColorScheme and Service:Visual Attributes for Settings where the colour can also be changed.
