The Server Manager enables data movement from a source database to a target database over a LAN or WAN. The Server Manager acts as the main gateway for configuration, management, and monitoring of replication jobs.
You work with a Server Manager instance from the
Server Manager
tab of the Data Replication Console.
The master Server Manager server is called the
Main server
. Typically, you run the Main server on the system where the source database runs. You can run the Main server on the system where the target database runs or on another machine. You can optionally define several
subservers
for a Main server. Typically, subservers are located on remote machines where the Extractor or Applier run. The subservers run the replication tasks and transmit the intermediate files.
After you connect to the Main server, you cannot later use it as a subserver. After you add a subserver, you cannot later use it as a Main server.
The Main server and the subservers that are associated with it comprise a
replication server group
. Each server can belong only to one replication server group. The Main server and its subservers store information about the servers in their replication server group in the
DataReplication_installation
/SM.db3 SQLite file. The Server Manager identifies the servers by using a unique server key. A server accepts messages only from the other servers in the replication server group.
The Server Manager Main server and each subserver also store information about the role of the server in the replication group in the
DataReplication_installation
/SM.db3 SQLite file.
You can connect to the Server Manager Main server from the Data Replication Console or the Server Manager Command Line Interface (CLI). For more information about the Server Manager CLI, see the
Informatica Data Replication Command Line Interface for the Server Manager
.
After you connect to the Main server, you can perform the following server management tasks:
