Re: Zendsvr and using AJP

Is this IBM's way of gently nudging us to IAS/WAS?

Hmmm. Googling on the jk_module found an IBM MTU for 6.1 that
specifically says:

"5.7.3 Tomcat

Tomcat servers will no longer be shipped as part of the 5761-DG1 product
in V6R1. Remove the following directive from customer configurations:

LoadModule jk_module /QSYS.LIB/QHTTPSVR.LIB/QZTCJK.SRVPGM

In addition, unless an open source version of Tomcat with the Tomcat
connector is used instead, remove the following directives from customer
configurations:

JkAsfTomcat
JkLogFile
JkLogLevel
JkMount
JkMountCopy
JkWorkersFile

If an open source version of the Tomcat connector is used, the
information above regarding third-party modules applies to the module
that is loaded into the HTTP server.


Now the interesting part is that this is talking about Tomcat but the
directive and module are used in Apache, not Tomcat so the MTU is a
little confusing.

So it looks like the AJP connector doesn't work on 6.1 but I'll keep
digging.

A little bit of further looking, I could not find the object QZTCJK of
any type on any of our systems. Are you sure the module name is right?

It won't start on V7 either.

I want to frontend Tomcat with my Zend server Apache instance and I
can't seem to get it to work (works like a champ in Windows). I
configured the workers.properties file and the uriworkmap.properties
file and added the following directives to httpd.conf.

LoadModule mod_jk /QSYS.LIB/QHTTPSVR.LIB/QZTCJK.SRVPGM


JkWorkersFile conf/workers.properties
JkMountFile conf/uriworkermap.properties

The Zendsvr Apache instance fails to start and also very unhelpfully
doesn't log anything anywhere I can see, so I can't tell what Zendsvr
Apache instance is cranky about. Using the directive listing doesn't
show any "JK" directives at all. Is this not supported on IBM i 6.1?
If I only attempt to load the module, it also won't start.

Anybody using AJP connectors on i?
