BBOU0510E WebSphere Bootstrap Phase 2 fails with communication error
 Technote (FAQ)
 
Problem
Phase 2 Bootstrap fails. In the Systems Management control region output BBOSMS the following communication error can be seen:

BBOU0510E Function gethostbyname() for hostname ip.name.com
failed with RV=0, RC=49, RSN=05620062, [EDC5049I The specified file
name could not be located.]
 
Cause
TCP/IP® setup is not correct to support WebSphere® Application Server for z/OS® V4.01.
 
Solution
  1. Perform an ONSLOOKUP command on the host name; for example:

    onslookup test2.inhouse.opers.org
    EZB3170I Server: server.name.com
    EZB3172I Address: 1.2.3.4
    EZB3170I Name: ip.name.com
    EZB3172I Address: 3.4.5.6
  2. Use the IP address 3.4.5.6 for a REVERSE ONSLOOKUP:

    onslookup 3.4.5.6
    EZB3170I Server: server.name.com
    EZB3172I Address: 1.2.3.4
    EZB3010I *** server.name.com can't find 3.4.5.6: Nonexistent domain


If you see the error message above, the reverse name resolution has not been set up for this domain. WebSphere Application Server requires reverse name resolution to run correctly.

After you update your TCP/IP® setup so that the host name resolves to an address and the address resolves to that same host name, the bootstrap runs successfully. If you continue to receive a gethostbyname failure, further review of your TCP/IP setup is required.
