Create Tables with Gateway Senders on page

Create tables in the source SQLFire cluster,
specifying one or more named gateway
senders that will send table DML operations
for replication.

Create Tables with Gateway Senders on page
234
Create tables in the target SQLFire cluster
with identical column denitions. The cluster
that will replicate DML operations must have
7
identical tables available before it can apply
the DML.
Create a Gateway Receiver on page 235Congure a gateway receiver in each
SQLFire cluster that will receive and replicate
8
table DML operations from another remote
system.
Test WAN replication by inserting rows in
tables that have gateway senders, and
verifying that those operations are replicated.

Start and Stop Gateway Senders on page 235Start, stop, and manage gateway senders and
receivers as necessary.

Add and Remove Gateway Senders and
Receivers on page 236
Change or remove gateway sender and
gateway receiver congurations as necessary.

Configure Locators for WAN Member Discovery
When you start a SQLFire locator in a WAN deployment, you must specify additional conguration options to
identify each SQLFire cluster in the WAN.
Important Configuration Notes
The -distributed-system-id option species a unique integer to identify the local cluster in which
the locator participates. Congure all locators for a given WAN site using the same
-distributed-system-id.
The -remote-locators option species the host and port numbers of one or more locators that identify
remote SQLFire clusters. The local cluster use the remote locators to connect to the remote SQLFire systems
for WAN replication. If a SQLFire cluster will replicate to multiple clusters (or if a remote customer uses more
than one locator), specify multiple remote locator addresses in a comma-separated list when starting a locator
as shown in these examples.
The -conserve-sockets option determines whether the locator will share a minimum number socket
connections between applications that connect to the local system and local SQLFire members that distribute
DML operations to remote WAN sites.
Note: Because of the increased messaging requirements involved in WAN replication, always set
conserve-sockets=false for SQLFire members that participate in a WAN deployment.
