RE: Dataguard Benchmark

Hi  

Plan of the Benchmark = ? If you mean an action plan of important steps ?

We have just started. I Shall send it to you shortly.  

Monitoring of Actual Bandwidth thruput (MBPS) used versus that set on WAN will be done .

(other than actual application transaction thruput rate (TPS) , OS
resources Utilizations )  

Thanks indeed

Did you plan that benchmark? What did you decide to monitor in the planning phase?

	Subject: Dataguard Benchmark 

	We are doing a Data guard Benchmark.

	 

	INFO.:-

	-----

	WAN Simulator :-

	We have a WAN Simulator with 2 routers at either ends of it. 

	Thruputs from 0 to 2 MBPS can be manually set as is required by
the run.

	 

	Application = Banking :-

	Transactions mainly OLTP in nature (Both DML & SELECTS) . 

	We can do CPU intensive batch Transactions too if advised by you
folks 

	 

	Machines = 2 machines of 4 CPUs each 

	Memory = 8 GB on each machine 

	O.S. = Solaris 9 

	Oracle = 9.2 

	Sniffer network tool ( to get volume of bytes transferred over
the WAN )

	Dataguard Setup will transfer Data thru the listener services :-

	i.e. init.ora - LOG_ARCHIVE_DEST_2 =
'SERVICE=<SERVICE_NAME_FROM_TNSNAMES.ORA>,. . .'

	 

	Execution methodology:-

	 

	Run Same Transaction's Volume in BOTH Logical & Physical


(Maximum Protection , Maximum Availability , Maximum performance )

standby modes 

	 

	 

	Qs What readings to be particularly monitored & measured? 

	Qs What thruput bandwidths should be benchmarked?

	Qs Does total Size of Existent Database-in-use matter to the
Benchmark? 

	Current Database Size = 3 GB

	Qs Does RMAN setup add any value to the Dataguard benchmark in
some way? 

	Else we will do Without RMAN, manually altering the various
modes

	Qs Any Sample Docs, Links on existing Dataguard Benchmarks?

	Qs Any else that will enable us to bring out a paper of
reasonable standard?
