Hi Bill/Bryan et al.,
I was trying to implement the reader-writers locking mechanism using shared
memory. I am using IPC::Shareable to implement this.
The apache-instances are currently running on only an individual server (say
A1) and all are able to access this shared memory; and things work just fine.
But on "live/production" environment, there are 4-5 servers (say, the others
are A2, A3, A4 and A5 respectively); each running several instances of
Apache-mod-perl.
Right now the shared memory is only on A1.
So if A1 goes down (due to any reason), all my other applications would be
starved as the shared memory was implemented on A1 and all instances across all
the servers were accessing this shared memory.
Is there any way I can have a shared memory mutually accessible to all the
servers?
So that in case A1 goes down, some other server can take take control of the
shared memory.
Any pointers would be much appreciated.
Thanks n regrds,
Ukh
