GRIDSCALE for IBM DB2

GRIDSCALE for DB2 has been specifically built to integrate with DB2 APIs and interfaces. GRIDSCALE for DB2 has also been tested by IBM at its lab in Markham, Canada for compatibility. Specific features for DB2 include the following:

DB2 CLI Clients

GRIDSCALE for DB2 provides a Call Level Interface (CLI) for DB2. This allows native DB2 applications to connect directly to GRIDSCALE transparently.

SQL Parser for DB2

GRIDSCALE for DB2 is 100% compatible with the SQL dialect used by DB2. This allows existing DB2 applications to use GRIDCALE for DB2 without any code changes.

xdb2

xdb2 is a cluster-friendly equivalent command line processor (CLP) to IBM's DB2 CLP. xdb2 allows customers to issue SQL and DB2 maintenance commands (e.g. load, runstats, etc.) through GRIDSCALE so that the command is applied to all the database servers. This allows the GRIDSCALE cluster to be managed like a single instance of DB2 reducing management costs.

DB2 Data Warehouses

GRIDSCALE for DB2 provides availability for business-critical data warehouses for round-the-clock operation. You can use GRIDSCALE for DB2 to provide disaster protection for warehouses in different geographic data centers.

In addition, GRIDSCALE enables you to perform maintenance on warehouses without outages. For example, if you plan on repartitioning a database across multiple database servers, GRIDSCALE for DB2 allows you to accomplish this without an outage.

Solution Comparison

This table shows how GRIDSCALE compares to other clustering and high availability (HA) solutions:

Solution	WebSphere Information Integrator (QRep)	HACMP	HADR	GRIDSCALE
Hardware Utilization	All Active - Requires manual load balancing	Active-Passive	Active-Passive	All Active
Horizontal Scalability	Yes - Requires manual load balancing	No	No	Yes
Automatic Failover	No	Yes	No - Requires other cluster solution such as Tivoli Systems Automation	Yes
Protection Level	Table	Database	Database	Database
Points of Failure	None	None	Disk	None
Consistent Data View	No	Yes	Yes	Yes
Easy to Use/Maintain	No	No	Yes	Yes
