Configurables

Configurables allow you to customize a Perforce service. Configurable settings might affect the server, the client, or a proxy.

Configurables that affect the server

Use p4 configure to set or unset configurables that affect a Helix Server. These configurables are also described in p4 help configurables. For more information on options for setting server configurables and their order of precedence, see p4 configure.

Note

Changes to most configurables are immediate. However, when you look up a specific configurable under Configurables - alphabetical list, check for the following:

After you change the value of this configurable, you must explicitly "stop" the server.

Note

p4 admin restart is not sufficient.

For UNIX, see Stopping the Perforce Service and Starting the Perforce Service.

For Windows, see Starting and stopping the Helix Server.

Configurables that affect the client

You can set configurables that affect the client in the following ways (shown in order of precedence):

As command line global options that are passed at server startup. For example:
```
$ p4 -u bruno -p perforce:1666 sync
```

As entries in a P4CONFIG file. Set configurables like this:

P4USER=bruno
P4PORT=perforce:1666

The following configurables can be set in a config file, and you can also set the variables listed for the p4 help environment command:

`filesys.binaryscan`	`filesys.bufsize`	`lbr.verify.out`
`net.keepalive.count`	`net.keepalive.disable`	`net.keepalive.idle`
`net.keepalive.interval`	`net.maxwait`	`net.net.rfc3483`
`net.tcpsize`	`sys.rename.max`	`sys.rename.wait`

As entries in a P4ENVIRO file.

You can use both P4ENVIRO and P4CONFIG files to define environment variables:
- use the P4CONFIG file for those variables that have different values for different workspaces
- use the P4ENVIRO file for those variables that remain constant for all projects. Values set in a P4CONFIG file override those set in a P4ENVIRO file.
As set by the p4 set command for Windows and OS X. For example:
```
$ p4 set P4PORT=ssl:tea:1666
```

Configurables that affect the proxy

You can set configurables that affect the proxy in the following ways:

Using a command line option. For example:

$ p4p -p tcp64:[::]:1999 -t central:1666 -r /var/proxyroot -v proxy.monitor.level=2

Using environment variables.

On Windows, using the p4 set command as follows:

C:\> p4 set -S "perforce_proxy" P4POPTIONS="-v myconfig=myvalue"
