I have worked on both the application side and the networking side, and have been heavily into the hardware side over the years. I have done hundreds of systems upgrades.
I worked part time as Sales Support for an IBM Business Partner doing some small maintenance projects. They decided to get out of the hardware business and concentrate on their core business, Application Systems Integration. When I was notified they were getting out of hardware sales, that left a couple of people I was working with up in the air. I did not want to bill them as an individual so I quickly put together an LLC.
I will be revising this as time goes on, but for now, I am offering the following: RPG, RPG-ILE, and RPG-Free programming as well as CL programs, Display file, CGI-DEV2, networking and Backup & Recovery. I have put together a few systems where the backups are done to save files and moved to off site locations. I’m also well versed in Linux, Mysql program in PHP,Python and Perl. I have experience with free-pbx for those that want to venture into Voip phones. I am able to pass data between the platforms by various methods. I can do system cleanup such as getting rid of unused device descriptions and backing off and archiving old applications, files and programs. Many older AS400 systems have files, journal receivers, and spool files that have been there for decades and in some cases this degrades systems performance. It also makes it hard to discern what you are actually still using the system for. I can also modernize some of the processes and take advantage of new features and functions many people do not take advantage of or even know exist.
I’m just completing a project of cleaning up a customers backups. They are locked into V5R4 and 9407-515 system. Because of application constraints they can not upgrade. Because of the age of the systems their reliability is coming into question. They purchased 3 additional systems they have located 2 of the systems in a remote location. Every night we backup their application libraries to save files and ftp to a synology NAS system. We maintain a 14 day rotation. At midnight we sync the local NAS to a second NAS at the remote location. Then the 3 backup systems pull the production libraries from the NAS at their location. We do a full system save to tape on Sundays in batch. We also copy journals to the NAS every 2 hours. This keeps 3 systems in sync with production with a single transfer from the Production system and eliminates the daily tape backup, they were doing previously. They maintain there 14 day rotation without having to keep track or store the tapes.
I’m retired now but like to stay active and engaged in systems and programming. I have customers running V5R4 up through V7R4. Being a small one man shop I keep my commitments down. I take on the occasional larger project. But I try to maintain room for my customers in case of an emergency. I like to think I can react with in a few hours if I’m needed.
