hi,
How does an Administrator helps Progremmers ?
This seems like a very generic question. Do you have something specific you are looking for, a situation you aren't sure how to handle?
Programmers usually need the System Administrator to configure system parameters for 3rd party database servers (/etc/system) and to configure filesystem or disks for use by the application. Most of the applications should be run by a userid other than root (although this isn't always the case). System Administrators and programmers usually work together to get the server running at the best possible for what they have. Monitoring applications and log files by both will help them understand what may be needed in the future as far as hardware requirements.
Most administrators I know have programming knowledge and can program a fair bit.
