Tungsten Cluster does not automatically synchronize information contained
within the user.map across all the nodes within the
cluster. The connector does not identify, track, or update
user.map content when it sees password changes.
Instead, the file must be updated by hand, through the
@script directive, and
synchronized across multiple hosts either manually or by using a script.
For example:
#!/bin/bash
for HOST in host1 host2 host3 host4
do
rsync /opt/continuent/tungsten/tungsten-connector/conf/user.map \
$HOST:/opt/continuent/tungsten/tungsten-connector/conf/user.map
done
If @script directives are used, the
corresponding scripts must also be included within this synchronization
step.
All servers within the cluster must have an identical
user.map configuration. Failure to have a
synchronized configuration may lead to clients being unable to connect
to the connector and database servers.
