RPCs sent to remote servers can contain parameters of types CS_LONGCHAR and CS_LONGBINARY. The Component Integration Services command cis_rpc_handling supports these types.
Sending long parameters to Adaptive Servers older than version 12.5 is not allowed, as earlier versions of Adaptive Server do not support CS_LONGCHAR or CS_LONGBINARY data. Component Integration Services examines TDS capabilities for the remote server prior to sending the RPC, and if the remote server cannot accept these datatypes, an error results.
