Speech Server Resources in N+1 Redundancy
Speech Server resources must be included in the primary node(s) vpshosts file(s).
During failover, the secondary node’s Pool Manager (PMGR) determines which
Speech Server resources to use according to the entries in the primary vpshosts
file(s). Speech Server nodes must NOT contain entries in their vpshosts files for
secondary (backup) components. The
$MPSHOME/common.standby/etc/vpshosts file on the secondary node
must NOT contain entries for the Speech Server nodes.
For example, in the following configuration:
the vpshosts files are:
# vpshosts (tmsi01)
#
# COMP NODE TYPE
1 - mps
2 - mps
3 tmsi02 mps
4 tmsi02 mps
10 tmsi100 mps
11 tmsi100 mps
10 osc10 oscar
11 osc11 oscar
tmsi01 (primary)
MPS1 MPS2
tmsi02 (primary)
MPS3 MPS4
MPS10 MPS11
tmsi100 (secondary)
osc10 & 11 osc20 & 21
