This subsection discusses the items to be evaluated when you use the standard adaptors.

• Number of adaptors to be created
  You must create as many adaptors as there are data input sources and output destinations. As mentioned in 2.2.2(3) Number of components that can be placed in a stream data processing system, you can manage a maximum of 64 input adaptors and 64 output adaptors per adaptor group.
  For details about the numbers of adaptors and streams, see 2.2.3(3) Relationship between standard adaptors and stream queue (stream).
  
• Processing to be performed by the adaptors
  For evaluation of the processing to be performed by the adaptors, see 2.5 Evaluating the processing to be performed by the standard adaptors.
  
• Number of adaptor groups to be created
  There must be a 1-to-1 correspondence between adaptor groups and SDP servers.
  
• Mode of connection between adaptors and SDP server
  You must evaluate whether the in-process connection mode or the RMI connection mode to use to connect adaptors and the SDP server. For details about the connection modes, see 2.2.3(2) Mode of connection between standard adaptors and SDP server.
  

You use the adaptor configuration definition file, which is one of the adaptor definition files, to specify detailed settings for the standard adaptors. For details about the adaptor configuration definition files, see 3.6 Creating the adaptor definition files and 9. Adaptor Definition Files.
