oracle jre use

Rentenaar — Wed, 29 Sep 2004 10:47:13 GMT

Hi,

We are running oracle 9.2.0.4 on 11.11
Had a problem with oracle, support told
me jre is not compatible with jvm
We have java1.4 installed and jre is 1.1.8
Oracle makes use of jre executable in scripts
and this goes thru the link in $ORACLE_HOME/JRE which is pointing to /opt/java/jre where jre 1.1.8 is located

This is the only location where I can find a jre. How should I upgrade to a higher jre if all new java version don't seem to have a jre included?

Hope you can help soon because we have a deadline for this project very soon

Tnx,

Jeroen

Sorry but interesting might be what's in your jre directory because I can't find a jre executable and this is what oracle is looking for in several scripts.

My install of java1.3:
/opt/java1.3/jre/bin
$ ls
ControlPanel* PA_RISC2.0/ keytool@ rmiregistry@
HPUXChildWrapper* java@ policytool@ tnameserv@
PA_RISC/ jcpm_server@ rmid@
$ find . -name jre
$ ls PA_RISC2.0
native_threads/
$ ls PA_RISC2.0/native_threads/
java* java_q4p* keytool* rmid* tnameserv*
java_q3p* jcpm_server* policytool* rmiregistry*

Searching other places for jre only leads me to 1.1.8 version

Jeroen

If memory serves.........

I think you tell the oracle installer where the jre is located shortly after you start it. So, you may be looking at an install issue and need to point Oracle to the newer jre.

I just got 1.4.1.2.04 from

www.hp.com/products1/unix/java/index.html

BTW thanks for the heads up, I'm getting ready to install 9.2.0.4 in a couple of months.

Hi Jeroen,
Just to show how I invetigate
E.G.
I look in oracle/product/.. for anything that can load an environment like oraenv else
helmut:/opt/oracle/product/9.2.0.1.0/bin $ file load*
loadjava: commands text
loadpsp: ELF-64 executable object file - PA-RISC 2.0 (LP64)
loadpspO: ELF-64 executable object file - PA-RISC 2.0 (LP64)
helmut:/opt/oracle/product/9.2.0.1.0/bin $ more loadjava
#! /bin/sh
#
# %W% %E%
#

unset JAVA_HOME
JAVA_HOME=/opt/oracle/product/9.2.0.1.0/JRE
export JAVA_HOME

JRECLASSPATH=/opt/oracle/product/9.2.0.1.0/JRE/lib/rt.jar:/opt/oracle/product/9.2.0.1.0/JRE/lib/i18n
.jar:/opt/oracle/product/9.2.0.1.0/jlib/javax-ssl-1_1.jar:/opt/oracle/product/9.2.0.1.0/jlib/jssl-1_
1.jar:$ORACLE_HOME/jdbc/lib/classes111.zip:$ORACLE_HOME/sqlj/lib/translator.zip:$ORACLE_HOME/javavm/
lib/aurora.zip
export JRECLASSPATH

SHLIB_PATH=$ORACLE_HOME/lib32:$JAVA_HOME/lib
export SHLIB_PATH

exec $JAVA_HOME/bin/jre -classpath $JRECLASSPATH oracle.aurora.util.Wrapper $JAVA_HOME/bin/jre -clas
spath $JRECLASSPATH oracle.aurora.server.tools.loadjava.LoadJavaMain "$@"

helmut:/opt/oracle/product/9.2.0.1.0/bin

So nothing in oraenv or so but in loadjava you may have your answer

All the best
Victor

Hi,

Found my answer by now. Installed 1.4.2 java
again, somnething was wrong in this installation. Made a new link in jre/bin directory called jre which point to java executable. Had to change some script
for commandline utilities of oracle.
Had another help from somebody which states
9.2.0.5 comes with new jre environment also. Probably best to upgrade directly to this new version. Also because I found out had to change http/jserv configuration as well.
