    Administration: RavenDB CLI

    Running RavenDB as a console application provides basic information along with a command line interface which can be used for getting additional information about the server and in performing specific commands.

    RavenDB can operate as service/daemon without console input. It is possible to access the CLI through a provided rvn (rvn.exe in Windows) tool included in each distribution package. The process is as follows:

    rvn admin-channel [RavenDB process ID]

    The rvn admin-channel uses Named Pipe Connection, and can connect to RavenDB CLI only when running on the same machine as the server, and with appropriate privileges.

    Information

    The rvn executable can be found in the distribution package under Server directory

    info

    Prints basic information to the console, including build version information, process ID (PID), bitness, and system hardware information.

    stats

    Online display of memory usage by RavenDB. You can separate into Working Set, Native Mem, Managed Mem, and Memory Mapped Size. Hitting any key will return to CLI's input mode (beware not to hit Ctrl+C / Break to avoid unintended a shutdown of the server).

    ravendb> stats
  Showing stats, press any key to close...
    working set     | native mem      | managed mem     | mmap size         | reqs/sec       | docs (all dbs)
 +  201.45 MBytes   | 17.36 MBytes    | 42.45 MBytes    | 2.02 GBytes       | 0              |      5,374,826

    log

    Enable (or disable) online log printing to the console.

    log <on|off|http-on|http-off|none|operations|information>
    Parameters Description
    on or off enables or disables log printing
    http-on or http-off enables or disables HTTP request log information
    none, operations or information sets the log mode to desired level 

    ravendb> log on

    Note

    If log is enabled using rvn admin-channel, the information will be displayed in the main console application. If RavenDB is running as a service, you will see the log output in the service log.

    gc

    Force Garbage Collection to a specific generation (0, 1 or 2). See GC.Collect Method

    gc <0|1|2>

    ravendb> gc 2
Before collecting, managed memory used: 48.92 MBytes

After collecting, managed memory used:  10.09 MBytes at 0.0078154 Seconds

    shutdown | q

    Gracefully shuts down the Server.

    ravendb> q

Are you sure you want to reset the server ? [y/N] : y
Starting shut down...
Shutdown completed
    Parameters Description
    no-confirmation Skips the confirmation question and shuts down immediately.

    restartServer, resetServer

    Gracefully shut down and restart the Server.

    ravendb> restartServer

Are you sure you want to reset the server ? [y/N] : y

    The two commands are equivalent.

    script

    Executes Admin JavaScript patches.

    script <server|database> [database name]

    ravendb> script database ProductionDB

Enter JavaScript:
(to cancel enter in new line 'cancel' or 'EXEC' to execute)

>>> return database.Configuration.Storage.MaxConcurrentFlushes
>>> EXEC
{ "Result" : 10 }
ravendb>

    Danger

    Running scripts can harm the database beyond recovery. Use with care.

    generateClientCert

    Generate a new trusted client certificate with ClusterAdmin security clearance.

    ravendb> generateClientCert <name> <path to output folder> <number of months until expiration> [password]
    Parameters Description
    name The name of the client certificate that is to be generated.
    path to output folder The path to the certificate. The path is relative to the server folder in RavenDB.
    number of months until expiration The number of months you want the certificate to last before it expires.
    password The certificate's password. Optional.

    trustServerCert

    Register a server certificate of another node to be trusted on this server. This is required when building a cluster where each node has a different certificate.

    ravendb> trustServerCert <name> <path to pfx> [password]
    Parameters Description
    name The name of the server certificate that is to be trusted.
    path to pfx The path to the certificate.
    password The certificate's password, if it has one.

    trustClientCert

    Register a client certificate to be trusted on this server with ClusterAdmin security clearance.

    ravendb> trustClientCert <name> <path to pfx> [password]
    Parameters Description
    name The name of the client certificate that is to be trusted.
    path to pfx The path to the certificate.
    password The certificate's password, if it has one.

    replaceClusterCert

    Replace the cluster certificate.

    Danger

    If replaceImmediately is specified, RavenDB will replace the certificate by force, even if some nodes are not responding. In that case, you will have to manually replace the certificate in those nodes. Use with care.

    ravendb> replaceClusterCert [-replaceImmediately] <name> <path to pfx> [password]
    Parameters Description
    -replaceImmediately Whether to force replace the cluster certificate even if some nodes are not responding. Optional, use with caution.
    name The name of the new cluster certificate.
    path to pfx The path to the certificate.
    password The certificate's password, if it has one.

    clear

    ravendb> clear

    prompt
