`Replica Node Dialog`:index:
|
|
****************************
|
|
|
|
Use The *Replica Node* dialog to view a standby instance being replicated
|
|
using log based streaming replication. Streaming replication allows a standby
|
|
server to stay more up-to-date than is possible with file-based log shipping.
|
|
The standby connects to the primary, which streams WAL records to the standby as
|
|
they're generated, without waiting for the WAL file to be filled.
|
|
|
|
The *Replica Node* dialog organizes the information through the following tabs:
|
|
*General*, *Replication Slot*

|
* The *PID* field is the process ID of a WAL sender process.
|
|
* The *Username* field is the name of the user logged into this WAL sender process.
|
|
* The *App Name* field is the name of the application that is connected to this WAL sender.
|
|
* The *Client Address* field is the IP address of the client connected to this WAL sender.
|
|
If this field is null, it indicates that the client is connected via a Unix socket on the server machine.
|
|
* The *Client Hostname* field is the host name of the connected client, as reported by a reverse DNS lookup
|
|
of client_addr.This field will only be non-null for IP connections, and only when log_hostname is enabled.
|
|
* The *Client Port* field is the TCP port number that the client is using for communication with
|
|
this WAL sender, or -1 if a Unix socket is used.
|
|
* The *State* field is the current WAL sender state.
|
|
|
|
Click the *Replication Slot* tab to continue.
