Configure the target server for the forwarding replica

The steps on this page assume you have logged into the target server The immediately upstream server for replica servers, edge servers, standby servers, proxies and brokers. See also 'upstream server' and 'central server'. as the P4 user with the access level of super. See Permission levels and access rights in the p4 protect topic of P4 CLI Reference. That user can have any name, but for convenience the examples use super:

p4 -u super login

On the target server, configure the forwarding replica. We might name the forwarding replica fwd-1667 because we will configure it to use port 1667:

p4 -u super server fwd-1667

A default server spec appears.

Spec configuration

On the target server The immediately upstream server for replica servers, edge servers, standby servers, proxies and brokers. See also 'upstream server' and 'central server'., configure the server spec for the forwarding replica by adding some configurables and setting their values. In this example, at line 1 the ServerID is fwd-1667, the replica host name is forward, and at line 5 the Address is forward:1667. For this example, line 13 indicates that the target server is named london.

Description:
    Forwarding replica pointing to london:1666

For the optional fields, you can use your own naming conventions.

For the Address field, see Communicating port information.

The DistributedConfig: section might contain fields starting any#, such as

any#P4LOG=perforce.log

any#serverlog.file.2=logs/commands.csv

These are options configured on the target server that, by default, apply to any server for which it is a target server. To override such a configurable for the replica, add it before or after the fields containing any#

For example:

any#P4LOG=perforce.log

any#serverlog.file.2=logs/commands.csv

P4LOG=perforce.read-only.log

serverlog.file.2=logs/my-subdirectory/commands.csv

Service user creation

In replicated and multi-server environments, a service user is required. See p4 user in the P4 CLI Reference.

The steps on this page assume you have logged into the target server as the P4 user with the access level of super. See Permission levels and access rights in the p4 protect topic of P4 CLI Reference. That user can have any name, but for convenience the examples use super:

p4 -u super login

Create the service user for the replication service. For example:
```
p4 -u super user -f service
```
The default user specification opens in your default editor. To make this user be of type service, add the following line:
```
Type: service
```
Save the user specification and exit your default editor.
Use the p4 group command to create a group for your service users and set the value of the timeout field. To avoid service users being logged out, consider using unlimited as the Timeout value. See Tickets and timeouts for service users.
Set the service user group protections to super in your protections table. See Service users.
Set the level of security to 3 or higher on the target server. See Server security levels.
For example,
$ p4 -u super configure set security=4
Ensure the service user is protected with a password:
$ p4 -u super passwd service
