killAllSessionsByPattern

The killAllSessionsByPattern command kills all sessions that match any of the specified patterns. [1]

The command has the following syntax:

db.runCommand( { killAllSessionsByPattern: [ <pattern>, ... ] } )

The command takes an array of documents that specify the patterns to match:

Pattern
Description
{ lsid: { id : <UUID> } }
Specify the UUID portion of the session id to kill.
{ uid: <BinData> }
Specifies the hash of the owner of the sessions to kill.
{ users: [ { user: <user>, db: <dbname> }, ... ] }
Specifies the owners of the sessions to kill. Requires additional privileges. See Access Control.
{ roles: [ { role: <role>, db: <dbname> }, ... ] }
Specifies the roles assigned to the owners of the sessions to kill. Requires additional privileges. See Access Control.

Specify an empty array to kill all sessions. [1]

To view existing sessions, see $listSessions operation or $listLocalSessions.

Tip

See also:

[1](1, 2) The killAllSessionsByPattern operation ignores sessions that have transactions in prepared state. See Behavior for details.

Killing a session kills any in-progress operations in the session and closes any open cursors associated with these operations.

The killed session may still be listed as a current session, and future operations may use the killed session. To view existing sessions, see $listSessions operation or $listLocalSessions.

The killAllSessionsByPattern operation ignores sessions that have transactions in prepared state. Transactions in prepared state refer to transactions with write operations that span multiple shards whose commit coordinator has completed the "sendingPrepare" action.

If the deployment enforces authentication/authorization, you must have the killAnySession privilege action to run the killAllSessionsByPattern command.

For patterns that include users or roles, you must also have privileges that grant impersonate action on the cluster resource.

Note

Users can kill their own sessions even without the killAnySession privilege action.

The following operation kills all sessions:

db.runCommand( { killAllSessionsByPattern: [ ] } )

The following operation kills all sessions that have the specified uid and whose owner has the specified role:

db.runCommand( { killAllSessionsByPattern: [
{ "uid" : BinData(0,"oBRA45vMY78p1tv6kChjQPTdYsnCHi/kA/fFMZTIV1o=") },
{ roles: [ { role: "readWrite", db: "test" } ] }
] } )
