ECPSync

Synopsis

[SQL]    ECPSync=n

n is either 1 or 0. The default value is 0.

Description

When ECPSync is enabled (n = 1), each time a SELECT statement is executed InterSystems IRIS® data platform forces all pending Enterprise Cache Protocol (ECP) requests to the database server. On completion, this guarantees that the client cache is in sync.

ECP is a distributed data caching architecture that manages the distribution of data and locks among a heterogeneous network of server systems. For further details, see Queries and ECP.
