I have an idea I wanted to bounce off of you good people. A client is upgrading from Informix 2.1 to 4.1. The hardware platform is an ALR 486/33. They need to have little down time in case of a hardware failure so a duplicate system is being configured. These two systems will be attached to each other via ethernet. We will be using 4GL/RDS with the On-Line engine. The upgrade has been ordered and should have been here yesterday but did not show up & time is real tight. Hence this posting. I want do have machine A sne machine B its transaction log file on an hourly basis or perhaps more frequent. Then have machine B roll its data base up to step with machine A. This way in case of a failure, machine B can be brought up with only a few minutes of down time. It's been a while since I've worked on Informix. Is there a way with the 4.1 On-Line I can tell it to start a new transaction log file without interuppting operations? I heard some place recently that On-Line 4.1 recommends many small transaction log files as opossed to a few large transaction files. But since I don't have the new product yet - I have no manuals. Any suggestions / comments are welcome!
