"Sybase e-Biz Impact integrates our critical systems which would otherwise be standalone silos of information."

Loma Linda University Medical Center—which operates some of the largest clinical programs in areas such as neonatal care and outpatient surgery in the U.S.—needed to upgrade its existing system and fix some long-standing issues with its mainframe message content. Using Sybase technology, Loma Linda lowered software replacement costs without disrupting hospital services.

Upgrading Disparate Systems
Loma Linda University Medical Center ( LLUMC) is recognized as the international leader in infant heart transplantation and proton treatments for cancer. Each year, the institution admits more than 33,000 inpatients and serves roughly half a million outpatients.

LLUMC needed to upgrade the current system and use the migration opportunity to fix some long-standing issues with the mainframe message content. Administrators also wanted to take advantage of the global monitoring functionality for the message traffic, and make sure the end results were stable and the migration process did not cause interruptions or problems in the overall functioning of the hospital's disparate systems.

A Smooth Migration
Now, LLUMC uses Sybase e-Biz Impact to integrate an array of specialty applications and standalone systems. Due to aging hardware and the need for enhancements, Loma Linda migrated to the 5.3 release of Sybase e-Biz Impact. With careful planning and some assistance from Sybase support, the migration was completed smoothly.

LLUMC had used TDM/Impact since 1993. The upgrade to Sybase e-Biz Impact 5.3 gave the team a chance to adjust the implementation architecture and freshen the translations and message routing within the system. They were also able to take advantage of the global monitoring capability for ongoing tuning and overseeing the health of the functioning system. The migration meant the hospital could continue building on its 11-year investment in a highly functional tool.

Retaining Functionality While Lowering Costs
The well-executed migration project achieved its goals. The mainframe messages were extended and the translations were adjusted to accommodate the changes.

"Sybase e-Biz Impact integrates our critical systems which would otherwise be standalone silos of information," said Keith Williams, integration architect at Loma Linda Medical Center.
LLUMC reduced costs by building a gateway from Sybase e-Biz Impact version 4.0 to 5.3, allowing both new 5.3 compatible software while retaining 4.0 existing functionality during the migration. By ensuring these specialized information silos work well with other applications, Sybase e-Biz Impact makes them more valuable to the hospital. Sybase e-Biz Impact lowers software replacement costs by extending the life span of these critical and aging applications and keeps them compatible with newer systems.

Keith Williams summarizes the project's success, "We accomplished this migration in what, for hospital based projects, is really a very short amount of time. It went quickly and smoothly without corrupting data or creating any real problems."
