Your existing FairCom RTG system can be upgraded to the latest version with very few changes. It is important to follow the procedures in this section to upgrade in a safe manner.
Compatibility Note: FairCom RTG features a new, streamlined folder structure. This change results in a new location for the server and other FairCom RTG components such as the utilities. Any existing scripts that rely on these locations will need to be updated. For more, see New FairCom RTG footprint.
Upgrade to the Latest FairCom RTG V3 Database Engine
While FairCom attempts to maintain backward compatibility when at all possible, transaction logs from earlier versions are not always compatible with newer FairCom RTG formats. For example, FairCom RTG V3 is built upon the latest FairCom Server, which introduces changes in the transaction log to accommodate new capabilities. Since backward compatibility is affected with this upgrade, then all of the steps in the following upgrade procedure are required.
Note: Existing data and index files are not affected by this update.
It is easy to install and use FairCom RTG with your existing files by removing prior transaction logs in a safe manner. Follow these easy steps, which are appropriate any time you are upgrading a c-tree installation:
- User# 00023 Server shutdown completed
Note: It is always advisable to use the most recent matching client version and utilities with your FairCom RTG server version. By updating the client as well as the server you will be able to leverage the new capabilities that otherwise would not be available
FairCom RTG Component Upgrade
You need to use the new FairCom RTG driver included with this release. For ACCUCOBOL users, this also means compiling a new ctreeacu.c module. Refer to this location if you need a refresher for how to do this. See the setup section for your compiler in the FairCom RTG User's Guide for details.
SQL Driver Upgrades
FairCom RTG includes a collection of SQL drivers to allow relational access through a variety of interfaces.
To upgrade the drivers, simply uninstall the existing driver, and then run the new Driver Installation program provided by FairCom. If no standalone driver is provided for your driver, then copy in the new libraries provided in this FairCom RTG package.
