Hope you have taken full backup before performing this. There's no way to get this done manually chaning of hostname from Instacne / DB is not possible as suggested perform a systemcopy but for this you have to get back with your old configuration by changing back hostname or using fullback.

Hi,

system name changed means ??? Have you changed SID or hostname ?

Check dev_dispatcher and dev_server* and std_server* logs and also paste here.

Thanks

Hi Thanks for reply

Change happened in only system Hostname

No changes made in <SID> or in IP address.

below are some log file may be useful for solving this issue.

Did you changed or adapted the hostname in listener.ora, tnsnames.ora files as well?

what does R3trans -x command say? (check the trans.log file)

[Former Member]

Hi,

So what did you really do ?

You had an up and running J2EE system and you just changed the hostname ?

If yes, I think you had to do an homgeneous system copy because for the J2EE system it is like you changed the physical host.

The hostname must be written in thousands of files...

@ output :r3trans -x is as follow :-

This is R3trans version 6.14 (release 700 -)

unicode enabled version

2EETW169 no connect possible: "connect failed with DBLI_RC_LOAD_LIB_FAILED."

R3trans finished (0012).

@ Dispatcher is not at all responding due to J2EE, because of this i am worried abt J2EE configuration. J2EE is in stopped / failed state.*

thanks

Best way to avoid all these errors to do the system copy. This method of changing hostname is not recommend as Java has hostname entry at number of places...

Thanks
