Introduction to WSRMIntroduction to WSRM

WSRM is a resource manager designed WSRM is a resource manager designed to manage applications and resources to manage applications and resources on Microsofton Microsoft®® Windows Server™ 2003 Windows Server™ 2003

Management is done using policies and Management is done using policies and schedulesschedules

Resources managed include CPU usage Resources managed include CPU usage and memory usageand memory usage

What To Do…and Not To Do…What To Do…and Not To Do…with WSRMwith WSRM

When a application can manage itself, When a application can manage itself, such as control CPU or memory limits, it such as control CPU or memory limits, it is not recommended to use WSRMis not recommended to use WSRM

Examples: IIS can manage memory usage Examples: IIS can manage memory usage and take actions based on the configured and take actions based on the configured options where WSRM cannot “take actions”options where WSRM cannot “take actions”

Always start with CPU throttling, or Always start with CPU throttling, or usage, and move to memory only when usage, and move to memory only when necessarynecessary

Do not use WSRM alongside other Do not use WSRM alongside other resource manager toolsresource manager tools

Why Use WSRM in Web Why Use WSRM in Web ApplicationsApplications

Web applications is one, if not the most, Web applications is one, if not the most, “unmanaged” environments on Windows“unmanaged” environments on Windows

Application code is often deployed on servers Application code is often deployed on servers without any direct understanding by without any direct understanding by administrators on what the application is administrators on what the application is using or going to useusing or going to use

This is commonly the case in Mainframe shops, This is commonly the case in Mainframe shops, etc. such as discussed in Stan Murawski’s webcastetc. such as discussed in Stan Murawski’s webcasthttp://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?culture=en-US&EventID=1032265860&CountryCode=US
