The snaping utility verifies that the LU 6.2 connections between the z/OS mainframe and the server are configured and operating correctly. Sybase recommends running snaping before you install Transaction Router Service (TRS) or DirectConnect for z/OS Option for DB2 Access Service Library.
DirectConnect for z/OS Option TRS or ACSLIB programs do not need to be active when you run snaping. The z/OS mainframe component of snaping, SYI1, does not use Open ServerConnect™ or Mainframe Connect Server Option for DB2 UDB. The snaping utility only tests the SNA support between the machine where you are running DirectConnect for z/OS Option on the LAN and the transaction processing region at the z/OS mainframe.
You can use snaping to collectively test all LU 6.2 connections defined to TRS or to test a single LU 6.2 connection.
