Remote Duplicate Database Facility (RDF)
The HP software product that does the following:
Assists in disaster recovery for online transaction processing (OLTP) production databases
Monitors database updates audited by the TMF subsystem on a primary system and applies those updates to a copy of the database
on a remote system
S
scalability
The ability to increase the size and processing power of an online transaction processing system by adding processors and devices to a
system, systems to a network, and so on, and to do so easily and transparently without bringing systems down. Sometimes called
expandability.
server
One of the following:
An implementation of a system used as a stand-alone system or as a node in an Expand network.
The hardware component of a computer system designed to provide services in response to requests received from clients across a
network. For example, NonStop system servers provide transaction processing, database access, and other services.
A process or program that provides services to a client. Servers are designed to receive request messages from clients; perform the
desired operations, such as database inquiries or updates, security verifications, numerical calculations, or data routing to other
computer systems; and return reply messages to the clients.
set() method
A method used to modify a data item. For example, the Connection.setAutoCommit() method changes the transaction mode of the
JDBC driver's connection to an SQL/MX database. Compare to
get() method.
SQL context
An instantiation of the SQL executor with its own environment.
SQL/MP
See
HP NonStop SQL/MP.
SQL/MX
See HP NonStop SQL/MX.
statement pooling
A framework for pooling PreparedStatement objects.
stored procedure
A procedure registered with SQL/MX and invoked by SQL/MX during execution of a CALL statement. Stored procedures are especially
important for client/server database systems because storing the procedure on the server side means that it is available to all clients.
And when the procedure is modified, all clients automatically get the new version.
stored procedure in Java (SPJ)
A stored procedure whose body is a static Java method.
stub
One of the following:
A dummy procedure used when linking a program with a run-time library. The stub need not contain any code. Its only purpose is to
prevent "undefined label" errors at link time.
A local procedure in a remote procedure call (RPC). A client calls the stub to perform a task, not necessarily aware that the RPC is
involved. The stub transmits parameters over the network to the server and returns results to the caller.
