Purpose
This note shall assist customers who need to change the IP address and/or the host name of their server.
Scope
This article will NOT be of any help on how to change your network (DNS) and the OS network setup. It will merely mention the components that affect Oracle on OpenVMS.
Potential changes to the Enterprise Manager Grid Console and Grid Control Agent are outside the scope of this article.
This article has the following parts:
- generic introductory remarks
- IP address change
- node name change
- network checks applicable to both procedures

| General Remarks on this subject |
You can review your database links using the DBA_DB_LINKS view. Example: |
| A.3. Additional verification: Use the following command to search files under the ORA_ROOT directory structure for all occurrences of the IP address. |
| B. Node Name changes |
Use the following command to search files under the ORA_ROOT directory structure for all occurrences of the node name. |
| B.2. Files that might need to be changed. These changes are only needed if the disk portion of the directory path includes the node name. |
You can review your database links using the DBA_DB_LINKS view. |
| B.4. Datafile path names Your physical file specification for your database files may reference the physical device name instead of an OpenVMS logical. |
Check for other files and parameters that might need to be changed: |
For more information on renaming database files please see: <Note 115424.1> How to Rename or Move Datafiles and Logfiles Perform the following query when logged in as internal: |
This query shows all initialization parameters that use the node name. Make sure you repeat the query for both UPPERCASE and lowercase Node name. |
| B.6. Batch queue definitions If you run CRS or the Grid Control Agent on the server, make sure your batch queue is correct. |
| C. Verify your network setup To verify the network setup for Oracle on OpenVMS, we suggest the following checks: |
| C.1. Is SCSnode correct? |
Does it match C.2? |
| C.2. Are the TCPIP logicals correct? |
Does TCPIP$INET_HOST match C.1.? |
| C.3. Does NSLOOKUP bring back the correct values? Assume a Windows client: |
From the OpenVMS server: |
| C.4. Has your local hosts file be modified? |
| C.5. Does your NIC card reflect the correct value(s)? |
| C.6. Have your clients be modified to reflect the new node name and/or IP address? Files to consider are |
| C.8. Connection Manager and Firewalls If you employ Firewalls and Connection Manager, make sure those environments know about the new IP address and/or node name. |
