Note: ndisk64 had to be radically hacked about and features disabled to get it to compile so I would consider this different source code - don't expect all the options in the AIX version to be available.Linux for computers that use the POWER processor tools:.Note: The command-line options maybe different.Do not ask for support for the AIX 5 version.Compiled on AIX 6 TL7 SP3 runs fine on any later version and AIX 7.1 TL2 onwards.These files contains all the binary command files and scripts.You specify date in kilobytes (KB) output per secondĬreates, writes, and deletes files to push the JFS and JFS log hardĮxample script to create the file systems used by the scripts - you need to edit the file for your systemĮxample script to start a fake database RDBMS - you need to edit the file for your systemĮxample script to start a fake web server - you need to edit the file for your system Tests shared memory, semaphores, and shared messages in a ring of processes - takes 1 CPU
Hammers or touches memory - complied 64 bit so it has access large memory (many GBs) Uses the Modular IO AIX Expansion pack library must be installed (experimental not currently available) Hammers the disks compiled for large files so it can access large files (many GBs) Hammers the CPUs (can be slowed down to use a percentage) With a 20 line shell script and these tools, I don't have to spend a week of setup time. For example, I run a Performance Tuning Expert Class and need to quick setup many different workloads and problems to be solved.
Learn performance monitoring and tuning.Prove performance of machine upgrades or alternative disk configurations.Soak testing = check a new machine/disk to remove early life failures.
