@Resume

@Resume — Returns a paused database to normal operating mode.

Synopsis

ClientResponse client.callProcedure("@Resume")

Description

The @Resume system procedure switches all nodes in a database cluster from admin mode to normal operating mode. In other words, @Resume is the opposite of @Pause.

After calling this procedure, the cluster returns to accepting new connections and stored procedure invocations from clients connected to the standard client port. If any export clients connected to the client port were disconnected by @Pause, they will automatically reconnect and restart export processing once @Resume restores normal operation.

@Resume must be invoked from a connection to the admin port.

Return Values

Returns one VoltTable with one row.

NameDatatypeDescription
STATUSBIGINTAlways returns the value zero (0) indicating success.

Example

The following example uses @Resume to return the cluster to normal operation.

client.callProcedure("@Resume");
