Pratt & Whitney Canada Uses Quest Software’s Space Manager with LiveReorg® to Reduce Downtime and Accelerate User Response Time Space Manager with LiveReorg® allows Pratt & Whitney Canada (P&WC), a world leader in aviation engines, to reduce SAP system downtime from six hours a week to just a few hours per quarter. In addition, P&WC has improved overall system response time by approximately 20 percent, helping them to meet critical service levels.
The Challenge Pratt & Whitney Canada (P&WC) is a world leader in aviation engines powering business and regional aircraft and helicopters. The company also offers advanced engines for industrial applications. P&WC’s operations and service network span the globe. P&WC customers require 24x7 system access to track

Live reorganizations are automatic and problem-free—and we no longer compromise SAP system availability or performance in any way.” - Fernand Gosselin, Database Administrator for CSC, a consultancy working with Pratt & Whitney Canada
those engines and parts, so SLAs have been established to guarantee maximum availability for the global spare parts network. P&WC runs critical SAP applications used for maintenance, payroll, customer support and other company operations, supported by an Oracle 8.0.6 database. The SAP system contains over 22,000 tables (about four terabytes in total size), some with more than 80 million rows—and the system is growing daily.
When P&WC first went live with their SAP environment, the IT department had scheduled a weekly six-
hour maintenance window for hardware upgrades, reorganizations and maintenance. However, that window did not give them enough time to reorganize many of the larger tables. As business expanded,
was impossible using traditional reorganization procedures.

The Quest Solution The company evaluated several tools on the market, and the only tool that met all of their objectives was Quest Software’s Space Manager with LiveReorg®. Space Manager with LiveReorg’s patent-pending

P&WC has two sets of disks that are mirrored, resulting in four images of the production databases. Each
of these is approximately one terabyte in size. When they reorganize a table, they actually reorganize four copies of that table simultaneously. They can also schedule Space Manager with LiveReorg to run on its own without supervision—a big advantage to the IT department and system users. “LiveReorg has taken the work out of the equation for us. Live reorganizations are automatic and problem-free—and we no longer compromise SAP system availability or performance in any way,” said Fernand Gosselin, database administrator for CSC, a consultancy working with P&WC. “From a technical standpoint, what I like about LiveReorg is that there’s a lot of usable functionality. For example, before LiveReorg, a reorganization of a 17 GB table took 7.5 hours. With LiveReorg, that same task takes a total of three hours and the switch over of the reorganized table takes seconds. In addition, we can schedule reorganizations to run over the weekend and no longer have to baby-sit the system while the maintenance is running,” said Gosselin. In P&WC’s rapidly growing environment, Space Manager with LiveReorg has helped improve global response time by approximately 20 percent.
• Reduced SAP system downtime from six hours a week to a few hours per quarter • Improved overall system response time by approximately 20 percent, helping to meet critical SLAs • Freed up IT resources to focus on more critical tasks
The Bottom Line “Before LiveReorg, we had to produce reports to enable the manual procedures required whenever the SAP environment was down. Now the SAP environment is never down, so we’ve eliminated those manual procedures,” said MacFarlane. This frees the IT department from wasted time, allowing the IT group to focus on new initiatives important to the company. Aviation operations are extremely mission-critical; strict regulations, and stringent time requirements are enforced for aircraft servicing. Space Manager with LiveReorg has allowed P&WC to provide vital products and services to customer’s 24x7x365, while adhering to aviation industry requirements. “In our industry, we cannot fail. LiveReorg has enabled us to correct our SAP system hotspots quickly so that we can meet our business goals, maintain our SLAs [Service Level Agreements] to customers, and keep our system up and running with little or no downtime,” claimed MacFarlane.
