Consultant/Systems Administrator
Ferrellgas - 12/96 to 06/97


Creating an upgrade package to allow non-technical personnel to install SCO OpenServer 5, custom scripts and applications on one of four different hardware configurations used as point-of-sale database systems.

Key issues in this upgrade included prevening data loss, increasing backup reliability and fixing problems with the menu system that was written in Bourne shell script. BRU was selected a replacement for the existing backup package; this along with poorly written legacy code necessitated extensive rewrites and testing of new backup scripts. Of key importance was making the backup procedure as simple as possible to allow non-technical personnel to perform backups while preventing loss of important customer and sales information.

Problems resulting from differences between SCO OpenServer 5 and the previous version of SCO, incompability between SCO's program for creating and installing duplicate systems from tape, problems with the various old and unreliable tape drives used and other issues required creative solutions. Poor quality of legacy shell script code required extensive debugging and testing.

Creating multiple test systems, including final template systems from which upgrade tape and floppy sets were created.

Traveling to four remote locations to install test version of upgrade. Supporting upgrade and performing on-site hardware and software troubleshooting.

Technical writing of documentation for non-technical personnel to use in performing system upgrades at remote sales locations. Writing a shell script to poll all systems and determine their exact hardware configuration, then creating an MS Access database to manage the information gathered and enable matching of the correct tape format to each site's tape drive type. Generating hundreds of custom floppy and tape labels for upgrade sets using this Access database and the MS Word merge function.

Post-upgrade support: fixing reported bugs in backup and menu scripts, solving problems related to system settings.

Supervising and training the technical support staff. Reviewing problem reports in trouble ticket system and assisting with troubleshooting.
