How to create the patch file system in oracle apps R12.2

Below is an action plan to recreate the patch file system. You will need to make sure to have a valid backup of your system before you execute it as this plan will imply to remove information from your system and we might need to go back to the point the action plan is executed in case anything may not go as expected.

1) Adpreclone:

On the RUN File-System, source RUN File-System:

$ source EBSapps.env run

# RUN Admin server MUST be up for this step

# check status:

$ $ADMIN_SCRIPTS_HOME/adadminsrvctl.sh status

# start if needed:

$ $ADMIN_SCRIPTS_HOME/adadminsrvctl.sh start

# execute adpreclone:

$ cd $INST_TOP/admin/scripts

$ perl adpreclone.pl appsTier

2) Detach PATCH homes:

# This step is performed from the RUN file-system detaching oracle_homes on the PATCH file-system:

$ cd $FMW_HOME/oracle_common/oui/bin

$ ./runInstaller -detachhome ORACLE_HOME={oracle home} -silent

 # for each PATCH oracle_home

./runInstaller -detachhome ORACLE_HOME=/u01/app/fs1/FMW_Home/webtier -silent

./runInstaller -detachhome ORACLE_HOME=/u01/app/fs1/FMW_Home/Oracle_EBS-app1 -silent

./runInstaller -detachhome ORACLE_HOME=/u01/app/fs1/FMW_Home/oracle_common -silent

# The 10.1.2 Oracle Home needs a different syntax

$ ./runInstaller -removeHome ORACLE_HOME=<s_tools_oh> -silent

$ ./runInstaller -removeHome ORACLE_HOME=/u01/app/fs1/EBSapps/10.1.2 -silent

3) Copy RUN to PATCH:

# it may be helpful for RUN environment to be DOWN for this step

 # copy each of these locations from RUN to PATCH

 <APPL_TOP>                              [ /u03/oracle/VIS/fs1/EBSapps/appl ]

 <COMMON_TOP>                            [ /u03/oracle/VIS/fs1/EBSapps/comn ]

 <OracleAS Tools 10.1.2 ORACLE_HOME>     [ /u03/oracle/VIS/fs1/EBSapps/10.1.2 ]

4) Remove PATCH FMW_HOME directory:

[ /u03/oracle/VIS/fs1/FMW_Home ]

5) Disable ebs_login:

Linux#> sqlplus system/<pwd>

SQLPlus#> alter trigger ebs_logon disable;

6) adcfgclone:

$ cd <PATCH COMMON_TOP>/clone/bin$ perl adcfgclone.pl appsTier

For the prompts in this step:

Do you want to add a node (yes/no) [no] : no

Enter the full path of Run File System Context file : <absolute path to the Run File System Context file>

RC-00217: Warning: Configuration home directory (s_config_home) evaluates to <PATCH s_config_home>. A directory with this name already exists and is not empty.

Do you want to continue (y/n)   : y

This is expected as part of the rebuild.

Target System Port Pool [0-99] : <desired PATCH File System Port Pool>

This will be the PATCH File System port pool. Would suggest that the RUN and PATCH port pools be different by approx twice number of managed servers on this node.

7) Verify work:

In the new terminal - source PATCH file-system

$ EBSapps.env patch

$ echo $FILE_EDITION

In new terminal - source RUN file-system

# Run Admin server MUST be up for this step

$ EBSapps.env run

$ adop phase=fs_clone force=yes

8) Enable ebs_login:

Linux#> sqlplus system/<pwd>

SQLPlus#> alter trigger ebs_logon enable;
