Shared application tier file systems – Add a Node
Using a shared application tier file system has several benefits:
- Machines can easily be added to an existing system
- Disk space requirements are greatly reduced.
- Administrative tasks need only be carried out once, on any node
- An Applications patch only needs to be applied once, minimizing downtime
- It is easier to add nodes, to cater for more users and provide greater resilience

Step 1: Run rapid clone on the existing node (on racerp1)
$ cd $INST_TOP/admin/scripts
$ perl adpreclone.pl appsTier
Step 2: Mount the shared filesystem that you are going to add and the following Shared
Top's must be visible from all application nodes involved in configuration.
On racerp1 – NFS Setup
cat /etc/exports
/d01/oracle/RACDB/apps/apps_st/comn 192.168.1.6(rw)
/d01/oracle/RACDB/apps/apps_st/appl 192.168.1.6(rw)
/d01/oracle/RACDB/apps/tech_st/10.1.2 192.168.1.6(rw)
/d01/oracle/RACDB/apps/tech_st/10.1.3 192.168.1.6(rw)
service nfs restart
On racerp2
useradd applmgr –g dba
Note – Just verify uid is same on racerp1 and racerp2
cat /etc/password

mount 192.168.1.4:/d01/oracle/RACDB/apps/tech_st/10.1.2 /d01/oracle/RACDB/apps/tech_st/10.1.2
mount 192.168.1.4:/d01/oracle/RACDB/apps/tech_st/10.1.3 /d01/oracle/RACDB/apps/tech_st/10.1.3
Add Node – Concurrent processing server
Step 3: Copy the context file from existing node to new node which is now going to
participate in Shared Application Tier file system if the file is not accessible from new
node.
Note- Modify the hostname in the context file to the available database node.
<dbhost oa_var="s_dbhost">oraclerac1</dbhost>
cd /d01/oracle/RACDB/apps/apps_st/comn/clone/bin/
[applmgr@linux2 bin]$ perl adclonectx.pl addnode contextfile=/home/applmgr/RACDB_linux1.xml
