JDK Oracle 9i please give me some advice

[Gavin Clarke]

I've been told that for Oracle Enterprise Management server to work fully it needs JDK.

The server it's on is semi-production (L-Class, HPUX 11.0) so I'm reluctant to install new products without first trying to see if they'll cause problems. So I guess my question is, did anybody have problems installing the patches (see http://www.hp.com/products1/unix/java/infolibrary/patches.html) required for JDK 1.3 or JDK itself?

If there's any hints and tips you can spare I'd appreciate them.

Hi,
Oracle comes with a built-in jre, so you shuold be already able to use the OEM functionality.

In any case, you don't need to have the OEM installed on the server, you can install in on your PC.

I installed it in my notebook and use it to manage the various DB. Moreover, if you install in your production box, you need additional space, and you cannot install the latest patechset only on it.

You PC is usually very simpler to manager.

I take regular updates of the oracle products, with no impact for my production servers.

HTH,
Massimo

Hi,

I've only ever install 9i on Linux - which needs the JDK just to install.

I have installed JDK1.3 on many of our HPUX server without any issues, one tip is to make sure you have plenty of free memory available, and you include the java bin & lib directories in you path and it should all go ok!

Cheers,

Hmm, we only needed to install Java runtime for Oracle9i (OEM server) - not the full JDK (development suite - which is a lot larger than runtime).

Anyway, the Java SDK or JRE bundles from HP install easily and perfectly. Never had a problem with that - unless youre installing a newer version of Java than you already have installed as it replaces a link at time of install which may upset other applications. 11.0 and 11i usually come with Java (1.2).

Thanks for your lightning fast responses. I will need to talk this over with our DBA, who is unfortunately (not for him) on holiday at the moment until Wednesday. Perhaps I've jumped the gun a little, all I can do is ask for your patience.

Seems to me that the Oracle jre is currently version 1.1.8, could this be true?

[Massimo Bianchi]

Hi,
yes, oracle jre is always rather old and poor-performing. But it works...

Okay, it's not strictly Oracle Enterprise Manager we're worried about, it's the Management Server part of it, we're both running OEM on our PC's without any problems.

Do you have any advice about the Management Server?

Also can I ask how I can tell what version of java is installed, swinstall isn't helping me much. I'm thinking I should be able to work it out the answer is evading me though.

java version info :

hpwin057:/opt/java/bin>(glennie)> ./java -version
java version "HP-UX Java C.01.18.04 10/11/2000 14:45:13 murlly"

I can tell you that last week we updated Java to 1.3 on
a half dozen or so database servers. No real grief except space and that was ~.8 GB total.

Thanks again for all the advice. I'm awarding points based on the original problem, which actually now I look at what I wrote isn't described very well.

I'm trying to decide if I even need to install JDK for the Oracle Management Server, and the feeling I'm getting is no I don't, although if I did it wouldn't be too bad.

There's no java in /opt only in various jre directories so I'm guessing if it's installed there it won't cause problems with the link replacement Stefan mentioned.

I found the version of one of them

java version "JavaVM-1.3.0.01"
Java(TM) 2 Runtime Environment, Standard Edition (build jinteg:02/14/01-23:51)
HotSpot VM (build 1.0.1fcs jinteg:02/14/01-23:51 PA1.1, mixed mode)

not sure that this is really relevant if there's no java in /opt

Thanks for the advice about the space it takes Tim that's pretty reassuring.

If anyone is running Oracle 9i OEM Management Server without JDK, please let me know.
