With RSF Release 9.0, administrators can change the layout of physical files while in use.
Bug Busters Software Engineering has announced Release 9.0 of its RSF and RSF-HA applications for IBM i.
RSF provides an advanced managed-file-transfer layer for IBM i. RSF-HA is a complete high availability and data replication solution for the IBM i platform, bringing users more power at less cost than the competition, according to the company. Release 9.0 updates both the base and HA versions of RSF.
With Release 9.0, you can change the layout of physical files while they're in use! This release also introduces several HA performance and functional improvements.
Change File While Active
The new Change PF While Active (CHGPFRSF) command lets you change the layout of a physical file with minimal disruption. The file is fully available during the change, except for a few moments at the end when the new format is installed.
Adding a new field or otherwise changing the record layout of a large production file has always been a challenge. Native tools, like the Change Physical File and ALTER TABLE commands, run for a long time and do not allow updates to the file until the operation is complete.
By contrast, the new CHGPFRSF command makes changing the layout of large files practical. During the change, reads, adds, updates and deletes to the file are fully supported, as are operations such as adding, clearing and reorganizing members. CHGPFRSF changes the file format in the background, preserving all user changes made during the update process.
This new feature is available in both the base and HA versions of RSF.
Faster Role Swap
With each release, RSF has improved the speed and efficiency of HA role swaps. A role swap occurs when the backup machine becomes the production machine, either during a test or as a result of a real problem with the primary machine. With this release we introduce the concept of a standby journal. When replicating your system, having a standby journal in place on the target machine can speed up the process of swapping the target into production, should the need arise. RSF now creates and manages standby journals for you, keeping the receivers small and trim until such time as the machine is swapped into production and the standby journal takes over as the production journal.
HA Improvements
Several key enhancements to high availability processing are provided, including:
- A new tool to find and delete orphan objects.
- The ability to specify the default job name for library replication tasks.
- The ability, when ending replication jobs, to wait until the requested jobs have ended.
- More flexibility when specifying objects to include or omit from replication.
- Automatic handling of libraries with cross-dependent logical files.
- Faster handling of PF triggers and constraints.
- Automatic target release detection, making it easier than ever to replicate between systems with differing OS release levels.
- A new, easy way to change the synchronization attributes for all of your defined items at once.
- A new command that makes it easy to delete a journal and all of its associated pieces.

Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
IT managers hoping to find new IBM i talent are discovering that the pool of experienced RPG programmers and operators or administrators with intimate knowledge of the operating system and the applications that run on it is small. This begs the question: How will you manage the platform that supports such a big part of your business? This guide offers strategies and software suggestions to help you plan IT staffing and resources and smooth the transition after your AS/400 talent retires. Read on to learn:
