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, 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.
