This section contains the following subsections:
Configuration errors are often the cause of communications failure. To resolve these errors, you need the following information, which was created when the network was installed and successfully implemented:
CICS RDO definition
SNA /NCP definitions for the LU and associated logmode
SDLC or Token-Ring connection charts to the mainframe
TCP/IP connection charts to clients
For CICS LU 6.2, workstation SNA configuration
Sybase interface files for clients and TRS
Sybase security definitions, including client logins, connection groups, and transaction groups
Verify that this information is the same as it was before the error occurred. If it is not, determine whether a recent change is contributing to the problem.
