Table Of Contents
A boolean value that species whether you need to manually start the gateway sender. If you
supply a null value, the default is "false" and the gateway sender attempts to start automatically.
Use SYS.START_GATEWAYSENDER to manually start a sender.
ENABLEBATCHCONFLATION
A Boolean value that determines whether SQLFire should conate messages. The default is
false.
BATCHSIZE
The maximum number of messages that a batch can contain. The default is 100 messages.
BATCHTIMEINTERVAL
The maximum number of milliseconds that can elapse between sending batches. The default
is 1000 milliseconds.
ENABLEPERSISTENCE
A Boolean value that determines whether SQLFire persists the gateway queue. The default is
"False."
DISKSTORENAME
The named disk store to use for storing the queue overow, or for persisting the queue. If you
specify a value, the named disk store must exist. If you specify a null value, SQLFire uses the
default disk store for overow and queue persistence.
MAXQUEUEMEMORY
The maximum amount of memory in megabytes that the queue can consume before overowing
to disk. The default is 100 megabytes.
ALERTTHRESHOLD
The maximum number of milliseconds that an event can remain in this gateway queue before
SQLFire logs an alert. The default is value is "0."
SERVERGROUPS
A comma-separated String of server group names. SQLFire creates the gateway sender only
on those SQLFire servers and peers that are members of the specied server group(s). This
parameter cannot be null.
Note: The server group names that you specify are converted to all-uppercase
characters, even if you specify a quoted identier.
Note: You can congure both partitioned tables and replicated tables to use a
gateway sender. However, you must create replicated tables in the same server
groups as the gateway sender(s) that you specify in the CREATE TABLE
statement.
Example
Create and start a gateway sender with persistence:
CREATE GATEWAYSENDER cluster-1-sender
(
REMOTEDSID 2
ENABLEPERSISTENCE true
DISKSTORENAME cluster-1-wan-store
)
SERVER GROUPS (primary_sender_group);
