WAAS Capacity Planning TFO Connection Reporting?

For WAAS Capacity Planning I'm trying to work out a way to gather WAAS appliance and module TFO connection statistics over time for each device. I'm looking to gather the number of TFO connections at regular intervals to allow us to get an accurate picture of the current WAAS capacity utilisation. The central manager reports a "The TFO accelerator is overloaded (connection limit)" when the maximum TFO connection limit for a devices is exceeded but it does not tell you the number of connections that exceeded the limit on the box.
I've tried using the WAAS Monitoring XML API:
http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v421/monitoring/guide/MG_XML_API.html
But it does not allow reporting of this statistic as far as I can work out.
If you run "show stat conn" on a WAAS device it gives you the "Current Active Optimized Flows", but this is the current number of flows and not the maximum number of TFO connections reached since the counters were last cleared?
Current Active Optimized Flows:                                3258
   Current Active Optimized TCP Plus Flows:              812
   Current Active Optimized TCP Only Flows:              2453
   Current Active Optimized TCP Preposition Flows:    0
Current Active Auto-Discovery Flows:                         411
Current Reserved Flows:                                           99
Current Active Pass-Through Flows:                          540
Historical Flows:                                                      532
Does anyone know anyway of anyway to either manually gather this statistic from a WAAS appliance or module? Or poll this statistic from a monitoring system like Solarwinds?

Hello
As of WAAS 4.4.1 it comes with a WAN optimization MIB CISCO-WAN-OPTIMIZATION-MIB, if you want to use a 3rd party software like Cacti to graph over time.
http://www.cisco.com/en/US/customer/docs/app_ntwk_services/waas/waas/v441/configuration/guide/SNMP.html#wp1141055
This MIB provides information about the status and statistics associated with the Application Optimizers.The following objects from this MIB are supported:

•cwoAoStatsTotalOptConn
•cwoAoStatsTotalHandedOffConn
•cwoAoStatsTotalDroppedConn
•cwoAoStatsActiveOptConn
•cwoAoStatsPendingConn

This MIB also provides information about TFO statistics. The following objects are supported:
•cwoTFOStatsTotalHandledConn

Any std report in Capacity Planning showing only dispatched orders/opns ?

Hi CRP gurus:
Does SAP has any standard report/transaction in Capacity Planning that shows (or has a selection for showing) only "dispatched" orders/opns ?
- Chetan

Chetan,
Use transaction COOIS. In this choose Operations, System status as DSPT at operation level, enter plant and execute. You will get only orders and the operations which are dispatched in this plant.
You can navigate to the capacity planning table from the selected records through order change.
Hope this is ok with you,...reward points..and close.

Machine capacity planning and efficency

Dear Guru,
I have number of machines and i want there individual capacity and efficency can we see that by any report or any tcode to see all capacity of machine.What is capacity leveling.
Is thee any configuration for capacity planning.
Thanks in advance

Hi, the following configuration steps involved in the capacity planning: SPRO --> IMG --> PRODUCTION --> CAPACITY REQUIREMENT PLANNING Capacity Requirements Planning: 1) Define time units 2) Define Capacity Category 3) Set up Capacity Planner. 4) Define parameters 5) Define Standard value key. 6) Define Move time matrix. 7) Define Setup matrix. 8) Define Control Key. 9) Define Shift Sequence. 10) Define Key for performance efficiency rate. 11) Define Formula parameters. 12) Specify Scheduling type. 13) Set up Production scheduler group 14) Select Automatically. 15) Define Scheduling parameters for Production orders 16) Define Scheduling parameters for networks. 17) Define Reduction Strategies planned/ production orders. 18) Define Reduction Strategies for network/process orders. 19) Define Control Profile. 20) Define Selection profile. 21) Define time profile. 22) Define Evaluation profile. 23) Define Strategy Profile. You can follow these above configuration steps in capacity planning Yes you need to active your all work center for the finite scheduling at the bottom of capacity view. Use all standard SAP configurations, Capacity Leveling Profile. Define time profile in OPD2. Define the strategy profile in OPDB Define the Overall profiles in OPD0. Then only you need to to active your all work center for the finite scheduling at the bottom of capacity view in work center.(CR02) Then run MRP with scheduling- 2 Lead time scheduling and capacity planning.(MD02) You will get your capacity requirement in CM01, or CM25/CM21.

Constraint capacity planning for Un-Routed items in ASCP

Hi All,

Dear ,
To answer the question for Capacity requirement planning on sales order I would say that MRP does only materials planning based on demand and reciept but never does Capacity Requirement Plannig .MRP generates Planned Order and susequently , production order can be genreted and farther you can carry out capacity requirement planning based on the work cente available capacity , requirement and load for those MTO orders .
But there are SAP business suit like APO-SNP APO PPDS which carriy our details scheduleing and caapcity check based on the demand situation : Sales Order ,Independent Order and does capcaity vaialbality chek for those demands while planning .
Now , here is the answer of your question :
1) Can Capacities are Scheduled as per priority given in SO automatically. : Not possible through SAP MRP but in APO-PPDS, APO-SNP-CTM , Herustic model .
2) Can revised availability dates will be reflected in SO. : It can be reflected as per the ATP chekc , Replishmenet Lead Time and re-scheduling horizon maintained in OPPQ-Carry all overall plant parametres.
3) Which reports will be useful for understanding consolidated availability date of material for given sales order/s. : You can check through MD04/MD05 or in sales order -Availaibility check -Schedule Line -Availaibility date .
Hope your are clear about the requirememt .

Collections Management (Capacity Planning): FICA Event/s?

Hello colleagues,
I have a requirement to apply additional criteria for Capacity Planning during dunning.
I need to restrict the volume of Dunning Activities by Regional Structure Group (after retrieving it from the Connection Object).
If anyone has any suggestions as to what FICA event to use, or where to find the count of proposed dunning activities after the proposal step is complete, that would really help.
In Event 300, I do not see any structure that gives me a count of proposed Dunning Activities. However, Capacity Balancing functionality is obviously retrieving the count and applying the limits based on configuration. I hope I do not have to loop through structure FKKMAGRP for the (in progress) Dunning Run ID to get the counts?
Thanks in advance.
Ivor Martin

Ivor:
Using Dunning by Collection Strategy method, this is delivered as standard. To do so on your own, use event 1799. In the standard event you could see where this is being executed for the collection steps.
regards,
bill.

Blocking of work center capacity for capacity planning

How can i block a work center capacity for capacity planning during Machine breakdown( via a Preventive maintenance order)?
i believe it will reduce machine capacity, yet how can i view this, against the previous capacity? is there a possible report or can it be shown through a transaction?

Hi,
In capacity header details screen not exactly as "can be used for capacity evaluation " but
"relevent to finite sceduling"
"can be used for several operations"
"long term planning"
these all indicators you can deflag this and check the results ,it may helpful to you.

Hi,
What should be the Heap size cannot be determined by the RAM size 32GB or 64GB. It depends on the Application...Application Functionality, How many Long living objects it creates , how many JNI calls it makes, How many Jars/Classes it loads, How many users requests your application at peak load, what kind of Caching you are using...etc
Above things are the points which can be used to determine the required Heap Size and the JVM tunning options.
There is no standard calculation or Formula available...The only option to determined the required Tunning parameters and JVM settings is...Load Testing and Performance Testing.
Thanks

Capacity Planning for Azure Managed Cache Service Spreadsheet Missing

I'm currently choosing between dedicated in-role caching and the azure managed cache service. It seems pretty clear that for in-role caching one must consider the cache access frequency when choosing the in-role cache size (as demonstrated by the capacity
planning spreadsheet found here http://msdn.microsoft.com/en-us/library/hh914129.aspx although the documentation states "Your application
is the only consumer of the cache. There are no predefined quotas or throttling. Physical capacity (memory and other physical resources) is the only limiting factor.")
It is less clear if this is also the case for the azure managed cache service since the documentation simply states:
“Now, there are no predefined quotas on bandwidth and connections. Physical capacity is the only limiting
factor and you only pay based upon the cache size. You can now focus solely on your application and its data needs.”
and the capacity planning guide spreadsheet found here:
http://msdn.microsoft.com/en-us/library/dn386139.aspx
does not lead the actual spreadsheet.
Is there some way to get the capacity planning guide spreadsheet for the azure managed cache service? If not, can someone tell me whether we need to consider cache access frequency (and not just size) when choosing the azure managed cache service?
Thanks!

Just kidding, I found the planning spreadsheets here:
http://www.microsoft.com/en-us/download/details.aspx?id=30000
That said, I'm still unsure of whether the data read/write frequency (bandwidth) is relevant in choosing capacity:
In role:
"Your
application is the only consumer of the cache. There are no predefined quotas or throttling. Physical capacity (memory and other physical resources) is the only limiting factor."
Managed:
“Now,
there are no predefined quotas on bandwidth and connections. Physical capacity is the only limiting factor and you only pay based upon the cache size. You can now focus solely on your application and its data needs.”
I'm confused because when using the caching capacity planner spreadsheet,
when the number reads/second is increased, a greater cache size is recommended. But why would I need a larger cache size if the same object is being read by multiple users and there is not limit on bandwidth?

Capacity planning 9iAS/Portal and/or 9iAS

I've looked all over metalink and otn, and can't find any good info on capacity planning for 9iAS/Portal, or 9iAS in general. #CPU, RAM, etc.
This is the closest I've gotten so far:
http://technet.oracle.com/products/ias/install-faq.html
http://otn.oracle.com/products/forms/pdf/6iscalability.pdf
Does Oracle just refers customers to their www.oracle.com/consulting ($?) group for this information, or is it documented somewhere that customers can see?
I understand that for a complex large scale enterprise Portal deployment that it would be necessary to hire consultants for hardware sizing and architecture, but there have to be some free guidelines that would be useful for customers with smaller requirements?

This was posted the day prior to our offline discussion. Am still interested in continuing our conversation (via this forum if you'd prefer).
Have you had a chance to look at the cacheability report that I had sent to you?
Aside from server clock issue I'd like to know what etags are used and generated by the portal infrastructure.
This is an important issue for our globalization project.
Many thanks and hope you're traveling safe!

Capacity planning requirement by individual capacity wise

Is it possible to get the report of capacity planning requirement by individual capacity wise. (Individual capacities assigned to work center).
I have checked Tcodes CM01 to CM07, but unable to get the same.

Hi
What i understand from your query is you want Individual capacities to work center means report as per capacity category wise..
In CM01 go to menu select Planning->selection-> capacity category wise enter your capacity category, slection list window will appear, click Detailed Capacity List...

It is a trial and error process.. Depends on the number of instances
the instance size should be restricted to 32KB only..
Look at tuning the engine in the Oracle 10GR3 BPM Admin manual... for all possible best practicess.
Especially look at the JVM heap size, instances threads, exec threads for automatic activities and manual activities as well as number of database pools and database connections for the engine db as well as external db..
Use Fuego.Fdi.DirHumanParticipant or DirOrganizationalRole or DirOrganizationalGroup instead of Fuego.Lib.Role for getting participants in groups etc..
This reduces the number of participants that should be in the cache and is helpful when an org has a lot of employees that are being pulled from the AD..
Look at some of the formulas for sizing etc..
One such formula in the manual is:-
Maximum Database Connections >= (# Interactive Exec Threads + # Automatic Exec Threads)
Make sure most of your instance variables are of the Category SEPERATED so that they consume less space and the instance size reduces..
I think the number of Project Variables should not be more than 256 and the number of Business Parameters should be more than 64.. Please check on this..
Depending on the number of instances and the size of project, make sure you run only a certain number of projects on one engine...

Capacity planning tables.

Hello everyone,
I have a requirement to extract Capacity Planning data from ECC into BW. I see that Capacity Planning report can be generated from CJ2B transaction. I also found that the structure for this is CYSTANDA. For extraction purposes I wanted to find out which tables are used to get this information and how CYSTANDA structure is populated.
Can someone please enlighten me?
Thanks in advance.

Welcome to SCN!
You can determine this very easily yourself by running a performance trace (transaction ST05) against the transaction you are interested in (CJ2B).
