java.net.UnknownHostException when installing Oracle on 11.23

joe clark — Wed, 31 Aug 2005 15:23:54 GMT

Hello, has anyone run into this problem when installing Oracle 9.x or 10G on 11.23 PA-RISC OS. The java that is loaded is jre 1.4.2. The above error happens early on in the process.
It looks like the Oracle script is bringing back the localhost IP.Any ideas would be appreciated.
Thanks in Advance

Is

make sure that your host has all the prerequisite patches for the version of java you are running.

you can find the patch information on the

http://www.hp.com/go/java

page and drilling down to page link containing the exact version of java you have.

Rac, nslookup gives the right replies back,
in fact Oracle v92.02 loaded ok, but v92.06 and 10G use a different installer, and a different version of Java.
Mel. we believe we have all the Java patches, but apparently Oracle doesn't let you use the java that is installed under /opt, even when you put that in the oraparim.ini (JRE_LOCATION), but rather uses a bin.jar from the oracle CD.
Thanks,

hi,

did you run the InstallPrep.sh (provided by oracle on metalink) script prior to the installation?

Hi,

looks like it is trying to do a gethostbyaddr.
You have 127.0.0.1 localhost in /etc/hosts AND the sequence "files dns" in nsswitch.conf ?
