Coserver Client Connections

All coservers in Extended Parallel Server can accept client connections. A coserver that accepts the connection for a particular client is called the connection coserver for that client.

To identify each connection coserver uniquely, the database server uses dbservernames of the following form:

dbservername.coserver_number

dbservername

is the value that you specify in the DBSERVERNAME or DBSERVERALIASES configuration parameter.

coserver_number

is the integer that you specify in each COSERVER configuration parameter.

This form of the dbservername is referred to as a coserver name. Extended Parallel Server uses the DBSERVERNAME and coserver numbers specified in the ONCONFIG file to generate coserver names. For example, if the DBSERVERNAME is myxps and the ONCONFIG file specifies eight coservers, the database server automatically generates the following coserver names:

myxps.1
...
myxps.8
