Re-Configuring Apex after host and DB SID change

Share on:

There are certain instances when you will have to make changes to your Oracle APEX server due to organizational requirements or other factors.

The following are the prevailing conditions:

  • Oracle HTTP Server
  • Oracle DB 11.2.0.3.0
  • Oracle Clusterware 19.10.0.0.0 for Oracle Restart
  • ORDS 3.0.11.180.12.34 installed
  • Apache Tomcat 7.0.59 installed

 

The assumption in this scenario is that the following have been completed:

  • Server Hostname changed
  • Server IP changed

 

To begin

Ensure the APEX services are shut down and you have conducted the necessary backups of the APPS install and Database (DB) 

 

Shutdown Apex Services on APEX PROD VM

  • Stop HTTP Server

[root@apexprod01 ~]# su – oraapex

  • Stop HTTP Server

export ORACLE_SID

 

[oracle@apexprod01 ~]$ vi /etc/oratab

Modify Listener as follows

#Backup file is /u01/app/oracle/crsdata/apexprod01/output/listener.ora.bak.apexprod01.oracle line added by Agent
LISTENER =

(CONNECT_DATA =

Now that the Instance name has been changed, we need to focus on changing the DBID as follows
