1. Tuxedo Advisor

2.  The Tuxedo advisor contains the following  Tuxedo Performance Advisor  Tuxedo Runtime Monitor  Tuxedo Runtime Action  Tuxedo Configuration (RM)

3. Tuxedo Performance questions  Questions:  How do you group services into servers? based on ????  How do you set the MIN/MAX instances of a Tuxedo Server?  How can I reduce the number of servers/instances?  How would you know which service to improve so you will have the biggest effect on your performance.  How can I decrease the system resources without effecting the performance

4. Tuxedo Performance Advisor recommends  Advise where should a Tuxedo Service be located based on historical performance information.  Group services based on their response times, service usage/frequency. “Common Profile”  Provide the MIN/MAX instances of a Tuxedo Server based on usage statistics.  Which service do I need to better in order to increase my overall system performance.

5. Tuxedo Service Performance  User experience is based on the following parameters:  Client code  Network  Tuxedo Server Queue (MSSQ or SSSQ)  Service runtime

6. Current Service distribution Server A Service X – 0.30 sec Service Y – 2 sec Server Queue Service X Service Y Service X Service Y

7. Performance Service distribution Server A Service X[1..3] – 0.30 sec Service Y[1..3] – 2 sec Server Queue Service X3 Service X2 Service X1 Server B Service Y2 Service Y1 Service Y2

8. Tuxedo Performance Advisor Report

9. Sample Report

10. Tuxedo Server Instance  How do you calculate the server MIN/MAX instances?  Based on statistical data:  Service performance.  Number of request.  When do you need to calculate the server MIN/MAX instances?  When service performance has changed.  When service usage changes.  When adding a new service to the server.

11. Tuxedo current MIN/MAX

12. Tuxedo new MIN/MAX

13. Tuxedo Runtime Monitor  Show services that are currently suspected in causing bottlenecks in the system  Monitoring Servers and instances  List all running servers  For each server show the number of live instances  Monitor server instance queue  The number of request waiting for execution.  Monitor number of clients that are connect to the domain  Monitor system CPU&Memory

14. Tuxedo Runtime Action  Start/Stop Tuxedo Server/Group/Instance  Restart Tuxedo Server instances one by one  Dynamic Actions:  Change service priority  Advertise/Un advertise a service  Suspend/Resume a server/service/interface  Change service/interface transaction timeout

15. Domain configuration information  Display the main parameters of a Tuxedo domain environment.  General information: Maximum number of servers for this domain. Maximum number of services for this domain. Maximum number of objects Maximum number of Queues  Show network connection ports (XXXADDR)  Show which Tuxedo capabilities are used by the domain: Security, CORBA, Events, Domain Connections, Network architecture, XA transactions

16. Domain configuration information (Cont.)  Show Application Server main parameters Minimum & Maximum instances, auto restart, enable statistics, Queue type, Server type, Server request queue Name For multithreaded servers: Initial & Maximum number of concurrently dispatched threads, Size of the stack created for each dispatch thread.  Advise about recommended changes to the domain configuration in regarding to performance.
