Dear Monks,

in my current project we will have several cooperating Perl-processes running on several machines.

What we are currently thinking about is not having these processes talk directly to each other but decoupling them via a queuing middle-tier in which each processes would communicate indirectly via (persistent) queues.

We are running on Linux and use Oracle for the backend.

The question is now how to implement such a queuing infrastructure.

I can currently see four ways for us to achieve this:

1) Roll your own.

2) Use Spread.

3) Use database-tables are queues.

4) Use Oracle Advanced Queuing.

Currently I am trying to evalute options 2-4 and would welcome any feedback on specific pros and cons that more experienced monks see.

Personally I quite like Spread (so far - I don't have a lot of experience with it), however I am also seeing the advantages of Oracle Advanced Queuing as it would permit us to have a process dequeue a message, do it's business-logic, update some database-state and finally enqueue new messages all in one database-transaction.

So could you please provide some enlightenment?

Many thanks

    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
