remote programs and commands In this presentation… –rpc concepts –rpc connections –rpc actions

remote programs and commands –used to execute remote commands or programs –results of command or program can be processed locally –similar to local programs (Call/Declare) and web services (WebCall/WebDeclare)

remote programs and commands rpc connection objects –represents a unique session to the remote server –Response property used to store message results from commands or program calls –Server property set to RPCServerOS400 for RPC connections

remote programs and commands RPCDeclare –used to define a remote program or procedure –similar to Declare and WebDeclare

remote programs and commands RPCDeclare arguments –Connection specifies the RPC connection object to use –Library specifies the host library that contains the program or procedure –Procedure specifies the name of the program or procedure

remote programs and commands RPCDeclare arguments –Alias specifies a local alternate name for the procedure –Returns specifies the return type of the procedure –Arguments describes the parameters used by the procedure

remote programs and commands RPCCall –used to execute a remote program or procedure –procedure must have been declared with RPCDeclare previously –connection from RPCConnect is also required

remote programs and commands RPCCall arguments –Procedure specifies the name or alias of the remote program or procedure –Arguments specifies the arguments to be passed to the procedure –Returns specifies the variable to store the procedure’s return value

remote programs and commands RPCCommand –used to execute a remote command –an RPC connection object is required –results of the command are available through the connection object –no declaration of the command is required

remote programs and commands RPCCommand arguments –Connection specifies the RPC connection object to use –Command specifies the command to be executed on the remote server

remote programs and commands RPCConnect –establishes connection to remote server –Connection String used like database connections –Connection String builder to create the string –user name and password prompted if not provided

remote programs and commands RPCConnect arguments –Connection name of the connection object to be created –Server must be set to RPCOS400 –Connection String specifies the details required to connect to the server.

remote programs and commands RPCDisconnect –disconnects from the remote server –connection can be left open for multiple commands and procedure calls

remote programs and commands RPCDisconnect arguments –Connection name of the connection to close
