Common Reasons for Application Bind Errors
A list of common reasons for application bind errors and recommended solutions.
Several problems can cause these errors:
- PORT statement conflict (EACCES). Common causes are:
- The port you are using is defined in PORTRANGE
- The started application name doesn't match the application name defined in the PORT statement
- The user ID associated with the application does not have access to the SAF resource specified on the PORTRANGE statement.
- Socket already bound to the port (EADDRINUSE). Common causes are:
- SO_REUSEADDR was not used
- The socket is bound to same port/IP address pair, without SHAREPORT (only TCP)
- IP address conflict (EADDRNOTAVAIL). Common causes are:
- IP address not valid (for example, a broadcast or nonexistent IP address)
- Various DVIPA failures (for example, JRDVIPACONFLICTIPADDR - DVIPA already active on another stack that will not release it.)
Resolving the problem
Review the common causes and take appropriate action.
