Subject [jira] Commented: (AMQ-2453) start/control-script is not suitable for professional environments
Date Wed, 20 Oct 2010 16:27:45 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-2453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=62703#action_62703
] 

Marc Schöchlin commented on AMQ-2453:
-------------------------------------

Rewriting shellscript to run with ksh might be real pain - because the implementation of ksh/sh
 varies between systems.
(i.e. between K&R and Sun ksh)

/bin/sh does also not provide real portability for complexer functions - the behavior of /bin/sh
varies between systems.

I really think it is no real pain to run this script in bash because bash is available on
all commodity unix-systems.

At least Linux, AIX and Solaris provide a preinstalled bash for years now. 

BTW: If there are problems on other platforms i can rewrite the code if you can send me the
debugging output of the shell (bash -x).

The new script is an advantage over the old mechanism because the old mechanism only supported
linux and macos...

> The start-scripts "activemq" and "activemq-admin" do not seem to be ready for production
use.
> Reasons:
> - Server does not run in background
>   => this can be done by redirecting output to a file and run in background
>   => in my opinion this should be implemented directly in java
>   => the console log should be written by log4j to <install-root>/data/console.log
> - The process should be started on a non-root user 
>   => use 'su -c "$COMMAND" - $RUN_AS_USER' 
>   => this should be defined in /etc/activemq.conf
> - The script should support a "reload" feature to reload the configurartion
>   (if activemq supports reloading)
> - The script should support a "status" option
>   => this should show a quick overview about the state of activemq
>   => this should return a value != 0 if the service is not working
>      (this is important for cluster integration)
> Does anybody already working on these items?
> Do you have suggestions for a implementation?
