If you are planning to migrate your application server to different machine or changing existing machine’s hostname, domainname or IP address here is list of things you should know in advance.
Discussion on this post if for 10.1.2.X and lower (Changing hostname on 10.1.3 and higher coming soon..)
Oracle Application Server components
Middle Tier- J2EE, Webcache, Portal, Wireless, BI, Forms
Infrastructure Tier- Identity Management(OID/SSO) & Metadata Repository
-
-
Things you should know before changing hostname, domainname, IP
1. Changing hostname, domainname of Metadata Repository is not supported (MR holds product data as well as OID/SSO data).
2. Use chgiphost.sh (unix) or chgiphost.bat (windows) in $OH/chgip/scripts directory to change hostname, domainname, IP address. 3. For changing middle tier hostname/domainname use option “-mid” with chgiphost.sh|.bat command
4. For changing Identity Management tier hostname/domainname use option “-idm” with chgiphost.sh|.bat command
5. You need orcladmin password for infra tier and any middle tier registered with OID/Infra Tier
6. If you change hostanme/domainname of instance hosting portal/sso, you need to reconfigure portal (using ptlconfig) and reregister with SSO (ssoreg)
7. Instance name doesn’t change by changing hostname or domainname. (When instance is initially created during installation name of instance is configured as <instance_name_you_provide> . <hostname>.<domainname> If instance name before host/domain name change was myinstance.oldhost.olddomain then it will remain same)
8. If instance (for which you wish to change hostname/domainname/ip) is part of OarcleAs cluster, you first have to remove it from cluster and add it later to cluster using “dcmctl” command
9. If instance (for which you wish to change hostname/domainname/ip) is part of OarcleAs Web Cache cluster, you first have to remove it from Web Cache cluster and add it later to cluster using “webcacheadmin” screen
10. If you are changing hostname/domainname for instance hosting OID, then change ldap.ora on all middle tier using this OID
11. Finally if anything goes wrong check logs in $OH/chgip/log

Hi,
Is there any script in $OH/chgip/scripts directory for changing source instance_name to target instance_name after clone is done??
Any reply would be appreciated..
Thanks for your time!

Amit
Amit,
If this is clone of middle tier then follow
this doc
else if this involves Infra Tier as well you need chapter 11 i.e. staging test instance from prod here
Above docs are for 10g r2
Do let me know if you need doc for 10g R3 apps tier
hi all,
while installing oracle i gave the hostname int he ip 127.0.0.1. my host name is server.oracle.com. now i have a problem. when i switch on the modem the oracle database connectivity is terminated. why is this happening. is there any ways to overcome this problem.
Karthiram,
Find out what IP your modem assign to your machine and then add below line in /etc/hosts (I hope you are on unix) file
127.0.0.1 localhost
server.oracle.com
Restart oracle database and listener and try.
Can you please how to achive similar functionality for BPEL?
Thanks,

hi..do u happen that when u change the hostname for IDM, then when u try to login to the OIDDAS website, it still point back to hostname before change?
@ KH
To change DAS URL
Login to Oracle Directory manager (OIDMON) in OID
Entry Management -> Oracle Context -> Products -> DAS -> OperationURLs
or dn=cn=OperationURLs,cn=DAS,cn=Products,cn=OracleContext
and look for value in attribute name orcldasurlbase and change it to new hostname

@ Cristian,
Your requirement is similar to configuring virtual host. Use these steps to change portal to virtual hostname here

In above architecture, OID and RAC is in Sun Solaris X86 (64 bit) box. Is it possible to move/migrate OID&RAC to new box with Sun SPARC64?
@Padmanaban,
As your MR is sitting on OID/RAC node so you can’t change hostname. You can migrate from X64 to Spac 64. Check with Oracle Support if these two are binary compatible (I doubt) then simply copy + paste for OID (ensure hostname,IP remains same) else go for migration.
For RAC , check RAC Docs on how to migrate from one system to another.
