Configuration File Tuning
We currently have a 2 node enterprise configuration but are thinking of increasing this. We can create as many file systems as required with each file system being allocated as much disc storage as required. Below is our current AIX server configuration. what is the optimum node and resource disk co...

parallel datasets
Given the scenario of a dataset being defined as 'overwrite' in a job using 2 nodes and each node had a seperate disk resource file system. If the nodes was increased to 4 nodes with each node having seperate disk resource file systems, would the file be seamlessly re-created across the 4 file syste...

Moving 'dataset' data segment files to new file systems
Currently all our data segment files for datasets reside on the same file system. I would like to spread the segment files across a number of file systems to reduce the I/O bottleneck but have the file descriptor remain on the current file system.
What is the best method of achieving this?

location of 'datasets'
Does having the dataset descriptor file is on a different file sytem than the data files cause any problems? The reason i am asking this is that the descriptor and data files are currently on the same file system and in order to reduce I/O queuing i would like to keep the descriptor file for new dat...

The disks are on SAN and their performance is fine. The issue is that on the AIX server side we are seeing queuing whilst the disks respond to each request for data. The issue is caused by batch wanting to access the same disks for data - when you have 40 batch jobs running at the same time all want...

Project File system Location
We are currently experiencing I/O bottlenecks on the unix file system that contains all our datastage projects.
Is there any benefit in creating seperate file systems for each project?

Assigning RAM disk to scratchdisk resource on AIX 5.3
I have read a number of articles around improving job performance by assigning RAM disk to the scratchdisk resource entry in the config file.
Will this work for AIX verion 5.3 and above?
