Host Name Length Restrictions in E-Business Suite 12.1 and 12.2

Robert Farrington
Applications Technology Integration

Oracle E-Business Suite Release 12 has a restriction on the lengths of the host names you can use.  The exact restriction depends on which of the following EBS Release Update Packs you have applied:

  • EBS Release Update Pack 12.2.5
  • EBS Release Update Pack 12.2.4, 12.2.3, 12.2.2, 12.1.3, 12.1.1

Each of these will be considered in turn.

Restriction in EBS Release Update Pack 12.2.5

When you run Rapid Install, you must ensure that the host names of your database node and primary applications node do not exceed 30 characters in length.  

Restriction in EBS Release Update Packs 12.2.4, 12.2.3, 12.2.2, 12.1.3, 12.1.1

The node names returned by the operating system for the database tier and application tier nodes must be no longer than 30 characters. If you configure your system to return only the host name for the node, then the host name must be no longer than 30 characters. If you configure your system to return the fully qualified domain name (FQDN), then the FQDN must be no longer than 30 characters, including the host name, domain name, and periods (.) used as separators.

Affected Rapid Install Screens

The following screens are where you need to ensure you enter host names that meet the current requirements.

    Hi Robert,

    Thank you for this note. I remember hitting this limitation in the installer, but never found out where this would actually cause problems. And this note doesn't really describe why the restriction is put in place. Do you have any more information where the length of hostname would cause issues if not stopped in the installer?

    Hi Barry,

    from memory, entering a hostname of more than 30 characters may cause issues with Oracle Applications Manager, concurrent processing and potentially certain code accessing the fnd_nodes table.

    In 12.2 it may also affect domain deployment

    Hi Barry,

    Concurrent processing is an area where this issue has been reported as causing problems. You may wish to refer to the original bug (18401015) that was logged.

    Hi Barry,

    Thanks for taking the time to provide this feedback.

    we have seen issues during patching when one of the machine inadvertantly had its hostname inadvertantly changed to the fqdn certain packages ( I forget the exact error ) were failing during the prepare phase itself.
