responce for that query. what is the internal process
happening.how it is taking that sql from the system?????

Answer Posted / tdguy

When a SQL is submitted, processing starts with PE.PE
checks for syntax, checks for security and handles
sessions. Then it builds a plan. This plan is communicated
to the BYNET. Based on the plan, BYNET signals the
appropriate AMPS. AMPS inturn, retrieve or store the data
in the respective vdisks. Communications between the
components involve acknowledgement and response signals.
