I’ve used this feature for years. It’s a system intensive process not to mention the bandwith consumption.
Sounds like you need to verify if your AS400′s PTF levels match up to the service pack level.
Or your AS400 is extremely small or our DASD utilization is too high to be using this tool.
When you’re using this utility to go out and download fixes for you don’t for get that Group PTF updates
and Cumulatives come in on multiple CD’s so you’re talking 5-10+ GB of data.
This tool is going to require the same amount of disk space for temporary storage of downloaded fixes.
You’ll need to ensure your network can handle the load as well.
It’s probably worth the hour of reading to understand this product before you run out using it.
There are PTF’s that address this problem.
