Login redirection is used by the Adaptive Server workload manager to send incoming connections to specific instances based on the logical cluster configuration and the cluster’s current workload.
Login redirection occurs at login time when an instance tells a client to log in to another instance because of load considerations.
You need not perform any additional configuration for client redirection; it occurs automatically.
This example includes the instances “ase1” and “ase2” on nodes “blade1” and “blade2” running in the cluster “mycluster.”
ase1 query tcp ether blade1 19786 ase2 query tcp ether blade2 19786 mycluster query tcp ether blade1 19786 query tcp ether blade2 19786
For example, if Active Messaging is enabled on “ase1” and “ase2,” and an application server tries to connect to “ase1” but “ase1” is unavailable, this login redirects to the “ase2” instance to perform the messaging operation.
See the Clusters Users Guide.
