CDR_ROUTER Environment Variable
Disables intermediate acknowledgments of transactions in the hierarchical topologies.
- default value
- 0
- range of values
- any number
- takes effect
- when Enterprise Replication is initialized or immediately after the cdr change onconfig command is used
When set to 1, the CDR_ROUTER environment variable disables intermediate acknowledgments of transactions in hierarchical topologies. The normal behavior for intermediate servers is to send acknowledgments if they receive an acknowledgment from the next server in the replication tree (can be a leaf server) or if the transaction is stored in the local queue. Use the CDR_ENV configuration parameter to set this environment variable. For more information, see CDR_ENV Configuration Parameter.
If CDR_ROUTER is set at the hub server, an acknowledgment will be sent only if the hub server receives acknowledgment from all of its leaf servers. Transactions will not be acknowledged even if they are stored in the local queue of the hub server.
If CDR_ROUTER is not set at hub server, the hub server will send an acknowledgment if the transaction is stored in the local queue at the hub server or if the hub server received acknowledgment from all of its leaf servers.
