Subject [jira] [Commented] (AXIS2-5110) Compatibility with WebSphere Application Server on z/OS
Date Fri, 12 Aug 2011 12:57:27 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-5110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13084083#comment-13084083

William Walsh commented on AXIS2-5110:
--------------------------------------

Upgrading our Axis2 version/release is non-trivial for us; but, I compared those three files
in the 1.5.5 and 1.6.0 source distributions and they're unchanged since 1.5.1.  So, I'm pretty
sure we would see the same symptoms at these levels too.

>             Project: Axis2
>          Issue Type: Improvement
>          Components: kernel
>    Affects Versions: 1.5.1
>         Environment: WebSphere on z/OS V7
>            Reporter: William Walsh
>            Priority: Minor

> In using Axis2 with WebSphere across multiple platforms we have found that once we invoked
a web service against Axis2 on WebSphere for z/OS that the application server would not shutdown
properly.  (The architecture on z/OS is very different than other platforms - it uses a number
of address spaces to host WebSphere and the control and servant address spaces would not terminate.)
 We asked IBM about this and it has to do with differences in how the JVM is implemented and
started by WebSphere on z/OS.  The long and the short of this is that Timer threads must be
defined as daemon to allow WebSphere to terminate properly on z/OS.
> I'd like to propose a patch for this and would like to know/confirm:
> Are these classes where I saw non-daemon threads created the appropriate places for change?
> /org/apache/axis2/util/threadpool/ThreadPool.java
> /org/apache/axis2/util/threadpool/DefaultThreadFactory.java
> /org/apache/axis2/transport/http/server/DefaultThreadFactory.java
> I would propose adding conditional code to force daemon threads when running on z/OS:
>   if (System.getProperty("os.name").equals("z/OS")
> Would this be appropriate, or do you feel the check needs to be more explicit; also checking
for WebSphere?
