Hi let me elaborate a bit MORE to get Better Suggestions from all Perl Monks

Platform Red Hat Linux 64 Bit 5. 4 with Perl 5.8

1. There are "A" number of Perl ProcessA running, which read from Linux QUEUE (ID - Amount - Details ) and make a Call to FCGI process B , Collect the response, based on the Response(Response gives Session ID for the ID )....TO 3

2. There is a FCCI process C , which is invoked by External systems for Session ID to provide value Success or Failure ..., which is read and Mapped to the DB with Session ID - Success/Failure

3 . The FCGI B after getting the response, based on the Session ID will query DB for the Session ID and Write in to a Linux Queue

All of these 3 Process are in Synchronous mode dependent on one another, we are trying to make this Asynchronous and achievable at high throughput. So to make the same , we need to share data across the 3 Process to remove the Database interaction

Coming to the Questions asked

1.These are Non stop running process , running in multiple instances

2.Mapping is required to be like Id- SessionID - Amount - Unit - Success/Failure - Number

3.Persistence - In terms of Data persistence across these processes on single server

4.All the 3 are perl Process

5. Yes worst case scenario need all the 3 to read write

6. Sorry for not being clear in my first description
