Problem IC68697
|
Status: Geschlossen |
FCM SENDER IS NOT SELECTING DESIGNATED NETWORK INTERFACE TO SEND DATA |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
If multiple network interfaces are available on a machine with
multiple logical partitions (MLNs), and each logical partition
is specified to use a designated network interface for
inter-partition communication (ie, via the netname column in
db2nodes.cfg), DB2 may not choose the designated network
interface to send data across partitions; it would instead let
the operating system (OS) choose interfaces that are deemed
appropriate to use. Depending on the actual workloads, this
behavior can potentially be suboptimal for send traffic if the
OS chose a single interface (or only a small subset) for all
logical partitions rather than fully utilizing all available
ones. |

****************************************************************
* USERS AFFECTED: *
* All of these criteria must be present for the problem to *
* occur: *
* - DPF *
* - MLNs *
* - multiple network interfaces on a machine *
* - user configured each logical partition to use a different *
* network interface (ie, via the netname column in *
* db2nodes.cfg). *
