Statserver Java issue: Failed to initialize Java host environment

[dreamc]

Happy to see the forum is still going strong after so many years (used it a lot probably more than 10 years ago).

I have upgraded the Statserver to version 8.1.000.38, installed the java extensions and configured the options to point to the new java path. I first used jre 1.7, but looking at the documentation found out that it will only work with version 1.4 or 1.5 (and also saw the same in this thread: http://www.sggu.com/smf/index.php?topic=5167.0) . So I have downloaded jre-1_5_0_14 (for linux) and installed it on the server. When starting up the Statserver I get the error Failed to initialize Java host environment.

Within the documentation it says you can use either libjava.so, libjvm.so, libjvm.a, or libjvm.sl. I configured the libjava.so with the right path but I get the following error:
[code]2013-07-05 15:12:04> Init: java-extension-loading-timeout option is set to 20.

2013-07-05 15:12:04> Init: Error: Java host environment initialization failed
[/code]

Trying libjava.so results in a crash of the statserver with logging not even showing the initialisation of the java environment. I have tried different 1.5 versions, all with the same result.

Now the documentation mentions that jvm-option needs to be configured (which doesn't seem to be have done previously), but it is unclear to me which values should be specified there.

Can anyone help me solve this issue?

StatServer has 2 states. On the logs the first appearance will be that it can't load it. But wait a few seconds and after all stats are loaded then you will see another Java message that it is ok.
Don't forget to define also JAVA_HOST
Best way is to go on CCPulse and use some Java Stat

[dreamc]

The "Java Host Environment is not initialized" message keeps appearing all through the logs, so it seems it doesn't start working. The server was supplied by another party with java 1.7 pre-installed. As I don't know if there are any other processes running on the machine which might need that version I thought changing JAVA_HOME might be tricky (unless I need to/can change it somewhere else).

Whats exactly why everyone must read the deployment guide and test you setup in lab environment!  Stat Server supports now support only the JDK version 1.4 or 1.5

[dreamc]

This is the lab environment, so no issues yet where it really matters. I'm trying to prevent them before it is too late. I installed the jre 1.5 manually, but since I can't do anything myself to the settings on Linux (pretty much locked down) I had hoped configuring in Statserver would be sufficient. So I guess I'll have to ask the sysadmin to change settings.

[cavagnaro]

:S Well that is another important step, you need admin privileges to configure it correctly.

[dreamc]

Have now been able to set the JAVA_HOME, PATH and LD_LIBRARY_PATH

JAVA_HOME is now set:
[code]/appl/genesys/gcti/jre1.5.0_14[/code]

PATH now includes:
[code]/appl/genesys/gcti/jre1.5.0_14/bin[/code]

LD_LIBRARY_PATH now includes
[code]/appl/genesys/gcti/jre1.5.0_14/bin[/code]

When I set the JVM path in the options like this:
/appl/genesys/gcti/jre1.5.0_14/lib/amd64/libjava.so
I see the error message that the file can not be opened:
[code]2013-07-10T11:12:04.849 Std 06053 Configuration for application obtained

2013-07-10 11:12:04> Init: Error: Java host environment initialization failed[/code]
After this 'Java Host Environment is not initialized' keeps appearing through the logs.

If I configure the option to /appl/genesys/gcti/jre1.5.0_14/lib/amd64/server/libjvm.so the application crashes almost immediately while adding Queues and Agents (and the log shows no reference to anything Java related)

Looking at the statserver deployment guide (the high-level procedure when starting up) I see that Stat Server verifies that the jvm-options section exists (but in the next step it says it is only used if anything is specified), so I'm wondering if I might need to configure something there (but since I see it trying to start the environment I don't think it is a must to be there).

You need JDK not the JRE

[René]

Hi dreamc,

You have to use 32bit Java and not 64bit as StatServer is 32bit app.

JRE is sufficient for StatServer.

R.

[dreamc]

Thanks, will try the jre-1_5_0_14-linux-i586.bin package and see if this solves the issue.

Just installed it and running this version gives the following:

The same thing happens when I configured the libjvm.so

Looking at the statserver directory we are running the 64 bit version (version 8.1.00.38), within the statserver directory there is a symlink which points statserv to statserv_64

*UPDATE* In order to test if it would work with the 32 bit version of java I have forced it to start up with statserv_32 and then the jvm initiates succesfully. Looking at the release notes of version 8.1.00.39 it states as new functionality "Support for the Red Hat Enterprise Linux 6 64-bit native", which is strange to me.

[René]

Hi,

I forgot that 64bit native StatServer application is available now. In that case you need 64bit JRE.

I did quick test on my lab platform (CentOS 5.9, Stat Server 8.1.000.37 - 64bit image) and it works properly with JRE 1.5_22 64bit. The 'jvm-path' option is set to '/usr/java/jre1.5.0_22_x64/lib/amd64/server/libjvm.so'

R.

Sorry guys to break the post but just curious René, any special reason to use CentOS 5.9 and not 6.x?

[dreamc]

Thank you for the quick test.

Installed that same version, JRE 1.5_22 64 bit, and changed the 'jvm-path' to the same libjvm.so as you've used, but when starting the application it crashes (my statserver version is  8.1.00.38) before I even see it trying to start up the JVM. We're running Redhat Linux.
