Cloning an existing ORACLE_HOME on Unix


By using the procedure shown below, we can replicate a ‘master’ copy of an Oracle software installation on any number of target servers. Not only will it ensure that Oracle software installations are standardised and include all the required patches, but will save considerable time and effort required to stage the software on multiple servers.
 How to Clone an existing ORACLE HOME on UNIX
 Source
Hostname: devu014
Oracle Home: /u01/oracle/product/10204
 Target
Hostname: devu007
Oracle Home: /u02/oradata/product/10204
  Use ‘tar’ to create a zipped archive of the source Oracle software. Note: use the  ‘-p’ flag to preserve file permissions
 oracle@devu014:pwd
/u01/oracle/product
 oracle@devu014: tar -pcvf 10204.tar 10204
 On the target machine scp the tar file to the appropriate location and unzip the archive
 crashdb:/u02/oradata> mkdir product
crashdb:/u02/oradata> cd product
crashdb:/u02/oradata/product> scp -rp devu014:/u01/oracle/product/10204.tar .
oracle@devu014’s password:
10204.tar                                                             100% 4389MB  14.1MB/s   05:12
crashdb:/u02/oradata/product> ls
10204.tar
 crashdb:/u02/oradata/product> tar -xvf 10204.tar
 Note the file permissions of the source is preserved after the files are unzipped on the target
 crashdb:/u02/oradata/product/10204> cd bin
 crashdb:/u02/oradata/product/10204/bin> ls -l oracle
–rwsr-s–x   1 oracle   dba       133931237 Oct 31 09:54 oracle
 Use the clone.pl perl script to perform the installation process which will also perform the relink and update of the Oracle Inventory
 perl clone.pl ORACLE_HOME=”/u02/oradata/product/10204″ ORACLE_HOME_NAME=”10204_HOME”
 ./runInstaller -silent -clone -waitForCompletion  “ORACLE_HOME=/u02/oradata/product/10204” “ORACLE_HOME_
NAME=10204_HOME” -noConfig -nowait

The specified service has been marked for deletion error

You may face the problem to delete Windows service using sc command.

When you try to remove a Windows Service with sc delete <service name>, you may encounter the following error:

[SC] DeleteService FAILED 1072:
The specified service has been marked for deletion.

There are several reasons for this error as follow:

[1] Microsoft Management Console (MMC) is opened. To ensure all instances are closed, run the following command to kill it:

taskkill /F /IM mmc.exe

[2] Services console is opened. This is the same as the previous point, since Services console is hosted by MMC.

[3] Event Viewer is opened. MMC is being used when you open Event Viewer.

[4] Process Explorer is opened. If it is causing the issue, closing it should lead to automatic removal of the service.

[5] Task Manager is opened.

Close any of the above running process and try again to delete service. If you still face the problem, there may be other issues as well which require further investigation.
