p4 configure

Set, view, and manage server configuration variables.

Syntax

p4 [g-opts] configure set [serverid#]variable=value
p4 [g-opts] configure unset [serverid#]variable
p4 [g-opts] configure show [allservers | variable]
p4 [g-opts] configure history [allservers | variable]

Syntax conventions

Description

Note

Although we recommend the syntax above, using serverid instead of P4NAME, the following syntax is still supported.

p4 [g-opts] configure set [P4NAME#]variable=value
p4 [g-opts] configure unset [P4NAME#]variable
p4 [g-opts] configure show [allservers | P4NAME | variable]p4 [g-opts] configure history [allservers | P4NAME | variable]

Configuration variables are used to control and customize the behavior of the Helix Core service. A configurable setting might affect the client, the server, or a proxy.

Tip

An alternative is using p4 server, which conveniently allows some configuration in the server spec. See the p4 server topic on the DistributedConfig: field.

Important

The configuration variables are described both in this Reference and at the command line:

Tip

The super user can use p4 [g-opts] configure history [allservers | P4NAME | variable] to display the history of configurables, which are recorded by the 2019.2 server onwards. See the Options.

Precedence

The following table shows how the value of a configurable variable is set, where 1 overrides 2, 2 overrides 3, and 3 overrides 4:

Precedence	How the value is set
1	Command line "-v" options that are passed at server startup. For example: $ p4d -v net.keepalive.idle=2700
2	Persistently, using the `p4 configure set` command. This method allows you to set the specified configurable for a named server or for any server. A configurable set for a named server has precedence over a configurable set for any server.
3	Using environment variables. For Windows, use p4 set -S Perforce, such as p4 set -S Perforce P4DEBUG="net.keepalive.idle=2700" and the value will persist On Unix, use the `export` command, which does not persist Note Certain server-related configurables are read-only. For example, the `p4 configure` or `p4 configure set` commands cannot change the value of the `P4ROOT` or `P4JOURNAL` environment variables.
4	Using default values (no action required).

Tip

You can use K and M to represent large numbers. For example, 10M is the default value for the dm.shelve.maxfiles configurable.

Viewing the values of configuration variables on one server

To display the configuration state of the current server, a named server, or any configurable, including a Helix Core environment variable, use

p4 configure show

Each configurable is displayed along with its value, where the entry in the parentheses ( ) indicates how the value was set:

If the output line is ...	the value was set by ...
P4PORT=20192 (-p)	p4d -p
monitor=2 (-v)	p4d -v
net.parallel.max: 10 (configure)	p4 configure
serverid=commit (serverid)	p4 serverid

Note that monitor is set to 2. To find out whether a specific configurable variable has been set in more than one way, specify that configurable variable:

p4 configure show monitor

which might output:

monitor=2 (-v)
monitor=10 (configure)

to indicate that p4d -v set monitor to 2, and p4 configure set monitor to 10. Because p4d has precedence over p4 configure, the output of p4 configure show indicates that monitor is set to 2.

Viewing the values of configuration variables on all servers

To display the configuration across all servers, use

p4 configure show allservers

The output might be similar to:

any: lbr.autocompress = 1

any: submit.allowbgtransfer = 1

paris-edge: P4LOG = /home/perforce/servers/edge1/log

headquarters-commit: P4LOG = /home/perforce/servers/commit-hq/log

where any means a configurable defined on the commit server that is used by all connected servers unless specifically overridden in that particular server's configuration.

Unsetting a value

To remove a custom setting of a configurable, use the p4 configure unset command. For example, to revert net.parallel.shelve.threads to its default value of unset (0), the command would be:

p4 configure unset net.parallel.shelve.threads

Tip

See "Recommended settings to configurables for security" in the Securing the server chapter of Helix Core Server Administrator Guide.

Stopping the server for some configurables

Changes to most configurables take effect immediately. For example,

monitor (enable/disable the p4 monitor command)
security (set the security level).

Changes to P4AUTH, P4PORT, the startup.N configurables used in replicated environments, net.tcpsize, and net.backlog require a restart. To restart the server, use p4 admin restart.

For certain configurables, such as ssl.tls.version.min:

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.

Setting configurables in multi-server environments

Servers can be identified by name. In replicated and multi-server environments, a master can control the settings of multiple replicas by specifying the server name as part of the configurable. For example, the following command sets the value of the serviceUser configurable for an edge server (tokyo_edge). The command is executed on the commit server.

$ p4 configure set tokyo_edge#serviceUser=svc_tokyo_edge

See Deployment architecture in the Helix Core Server Administrator Guide.

Accessing configurables when the server is down

If the Helix Server is not running or you cannot access the server, you can use the p4d command to list, set, and unset server configurables:

To list all server configuration variables, use the -cshow option. For example:
```
$ p4d -r $P4ROOT -cshow
```

To set or unset values, use -cset or -cunset. For example:

$ p4d -r $P4ROOT "-cset myServer#auth.ldap.timeout=30"
$ p4d -r $P4ROOT "-cunset myServer#db.replication"

For more information, see the Support Knowledgebase article, "Accessing Server Configuration Variables".

Options

`set variable=value`	Sets the named variable to the provided value.
`unset variable`	Unsets the named variable.
`show`	Shows the current configuration of the server currently specified by `P4PORT`. Note Regarding the maximum size of the `db.monitor` table, see db.monitor.shared configurable, and note that `p4 configure show` indicates the actual maximum, but `p4 configure show allservers` indicates a manual preference that is only enforced if sufficient memory is available.
`show allservers`	Shows the configuration variables for all servers known to the system.
`show variable`	Shows the setting of the specified configuration variable.
`show P4NAME`	If a Helix Server was invoked with `-In` P4NAME or with the `P4NAME` environment variable set to a server name, shows the settings of the named server. Important To avoid configuration problems, the value of `serverID` should always match the value of P4NAME if both are set. We recommend setting `serverID` instead `P4NAME`.
`history`	Records any changes to the value of each configurable in the db.configh table, which contains the name of the configurable, the targeted serverId, the old value, the new value, the user who made the change, the datetime of the change, the configureVersion number, and the serverId on which the change occurred.
`history allservers`	Shows the history of configuration variables for all servers known to the system.
`history variable`	Shows the history of the specified configuration variable.
`history P4NAME`	If a Helix Server was invoked with `-In` P4NAME or with the `P4NAME` environment variable set to a server name, shows the history of the settings of the named server. Important To avoid configuration problems, the value of `serverID` should always match the value of P4NAME if both are set. We recommend setting `serverID` instead of `P4NAME`.
`g-opts`	See Global options.

Tip

The output of p4 configure show only shows those configurables that have been changed from their default value at least once. Such configurables continue to show even if the value is specifically set to the default value.

Examples

p4 configure set "Replica1#startup.1=pull -i 1"

On the server named Replica1, set the startup.n configurable to poll 1 every second

p4 configure set rpl.labels.global=1

The server returns:

For server 'any', configuration variable 'rpl.labels.global' set to '1'

where 'any' means this setting applies to ALL servers, unless there is a local override for the same setting.
