1. If I use an software application(which connects to the database in the server) in my local pc, how many PID should be registered? Would there be PID for the session and another PID for socket connection?

msg_get_queue
MSG_GET_QUEUE(3) 1 MSG_GET_QUEUE(3)msg_get_queue - Create or attach to a message queueSYNOPSIS
resource msg_get_queue (int $key, [int $perms = 0666])
DESCRIPTION msg_get_queue(3) returns an id that can be used to access the System V message queue with the given $key. The first call creates the mes-
sage queue with the optional $perms. A second call to msg_get_queue(3) for the same $key will return a different message queue identifier,
but both identifiers access the same underlying message queue.
PARAMETERS
o $key
- Message queue numeric ID
o $perms
- Queue permissions. Default to 0666. If the message queue already exists, the $perms will be ignored.
RETURN VALUES
Returns a resource handle that can be used to access the System V message queue.
