1.1

Table Of Contents
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);
Information for the gateway sender is added to the GATEWAYSENDERS.
CREATE GLOBAL HASH INDEX
Creates an index that contains unique values across all of the members that host a partitioned table's data.
Syntax
CREATE GLOBAL HASH INDEX index-name
ON table-name (
column-name [ , column-name ] * )
Description
A global hash index in SQLFire is like a partitioned table with hash partitioning on the index columns. Only
equality based JOIN Operations involving index columns use the hash index for pruning the set of members
required to service the query. SQLFire creates global hash index implicitly for foreign key and unique key
constraints when the partitioning column differs from the primary key of a table.
The index data itself can reside in multiple members, including members other than those that host the table's
data but restricted to data stores (i.e. members booted with 'host-data' as true).
Example
- create a hash based globally unique index
