php-java-bridge-users Mailing List for PHP/Java Bridge

Thank you for your response. I agree with you in installing everything with 
rpms.

Maybe this is my lack of fully understanding how RPMS work. But I must 
compile php with the following options,

--prefix=/usr/local/php5
      --with-apxs2=/usr/local/apache2/bin/apxs
      --with-libxml-dir=/usr/local/lib
      --with-mysql=/usr --with-mysqli=/usr/bin/mysql_config
      --enable-soap --enable-sockets
      --with-config-file-path=/usr/local/php5/lib
      make  --with-pgsql=/usr


The reason why I manually installed php is because I couldn't figure out how 
to tell the RPM to include these options. I think a solution to this would 
allow me to insall php-java-bridge as an RPM.

Any ideas?

Thanks.

Everything you install yourself is ignored
intentionally.  Please always install from RPM for two
reasons:

1. RPM keeps the dependencies in a database. If you
manually install software into /usr, the RPM database
content gets out of sync with the file system.

2. RPM's contain SEL contexts. Java, php and the
php/java bridge rely on the correct security contexts.
If you break them, you must switch off SEL entirely or
provide your own contexts and relabel the entire file
system.


However, it is possible to compile your own local
versions of apache/php and the php/java bridge into
/usr/local, please see the INSTALL document (section
"Install from source") for details

Jost Boekemeier

Hi Massimo,

It's a known bug in the thread pool of version 2.0.7. 
Its hould be fixed in 2.0.8, please see the changelog
entry for getNextRunnable from 2005-08-23 for details.

This problem appears only when you have very short
scripts; if one sees this message in a production
environment, I suggest to switch off the thread pool
or to upgrade to 2.0.8.

Hi Jost,
=20
Having at last connected a PHP script to WebSphere MQ via the
php-java-bridge I've been benchmarking the connection with Apache "ab",
and while the results are good performance-wise, the following error is
intermittently logged:
=20
Exception in thread "JavaBridge" java.util.NoSuchElementException
        at java.util.LinkedList.remove(LinkedList.java:644)
        at java.util.LinkedList.removeFirst(LinkedList.java:134)
        at
php.java.bridge.ThreadPool.getNextRunnable(ThreadPool.java:33)
        at php.java.bridge.ThreadPool.access$100(ThreadPool.java:7)
        at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:20)

The error occurs only when I specify a concurrency level greater than 1
- in my current setup it is most evident when running 5 concurrent
clients, which is not that much load.
=20
From what I gather there may be a problem with thread synchronization in
the bridge; what do you think?
I'm still running php-java-bridge v.2.0.7 and plan to upgrade, but can't
see anything in the changelog that addresses a similar problem.
=20
On a side note, I observe decreasing throughput after running several
benchmarks with identical parameters: the slugginess goes away when I
restart the bridge ... do I need to explicitly invoke some "garbage
collection" method at script's end?
=20
Bye,
Massimo
