BackupExec 2012 (14) on newer Linux
In particular – Oracle UEK, which “claims” to be 2.6.39-xxx, but is actually 3.0.x with a lower version number. Several misbehaviors (or differences) of version 3 can be found. One of them is related to BackupExec. The service would not start on OEL6 with UEK kernels. The cause of it is an incorrect use of a function – getIfAddrs. Everything can be seen in this amazing post. The described patch works, at least to allow the service to start. Check out the comments for some insights about how to identify the correct call.
I am re-posting it here, so it can be found for Oracle Universal Enterprise Kernel (UEK) as well.
