Capacity Planning Question

I need to design a solution to replace some FEPs by Cisco routers with CIP interfaces. The main aspect of this job is choose the appropriate number of routers and the capabilities to support SNA sessions provided by FEPs. I know that the one of the key aspect is the rate and size of transactions.
I would like to know how I can get this informations from mainframe. There is any design guide explain how to define the number and configuration of routers ?
Best Regards

Only the transaction rate is revelant and important.
DLSw only keeps track of the number of PU (i.e. number of LLC2 connection and DLSw circuit). It does not keep track of the number of LU. In other words, DLSw uses the same router RP/CPU resource in the following cases:
1. 100 PUs with 2500 LUs and no transaction
2. 100 PUs with 100 LUs and no transaction
The only process that is PU related and consumes router RP/CPU resource is LLC2 keepalive. The router has to Receiver Readys (RRs), which is more or less LLC2 keepalive, when the PU is idle for the period of LLC2 idle-time. The default value for LLC2 idle-time is 10 second. If the router has a lot of PUs on it and consumes a lot of CPU/RP cycle on the process "LLC2 timer", just increase the LLC2 timer to 60 second.
There is no rule/formula between transaction rate and CPU cycle. The TME (Techincal Marketing Engineer) just pump traffic into different routers and record the CPU utilization. As the router uses the same amount of CPU/RP resource on packets with 40 bytes and packets with 1000 bytes, the DLSw white paper below only shows transaction rate vs different router platforms:

Capacity planning question for 11g DB server

We are building a new 2-node RAC cluster for our new application; what is the general rule of thumb for number of CPUs, memory?
env: 2-node RAC, RH5, 11gR2

If this is a packaged application, the application vendor should be able to help you with this sort of sizing since they know what factors are going to be most important to resource utilization.
If this is a custom application, you'd need to talk to the development and architecture teams that built the application. Without any idea what the application is doing, we don't even know what metrics to ask about in order to guess at the requirements. For some systems, it will be the number of users. For other systems, it will be the types of users or the modules that are configured. Some systems will scale based on the amount of data, others will be independent of data volume but will depend on the number of middle tier servers. And it will always depend heavily on how efficient the code is-- a system that is built to take advantage of Oracle and to maximize efficiency, for example, will require much less hardware to do the same amount of work than a system that is built to be database agnostic that hasn't been optimized for efficiency.

Bandwidth Utilization Avg or Max for capacity Planning best practice

Hello All - This is a conceptual or Non-Cisco product question. Hope you can help me to get this best industry practice
I am doing a Capacity planning for the WAN Link Bandwidth. To study the last month bandwidth utilization in the MRTG graph, i am seeing two values
Average
Maximum.
To measure how much bandwidth my remote location is using which value i have to use. Average or Max?
Average is always low eg. 20% to 30%
Maximum is continuous 100% for 3 hour in 3 different intervals in a day and become 60% in rest of the day
What is the best practice followed in the networking industry to derive the upgrade size of the bandwidth by using the Utilization graph
regards,
SAIRAM

Hello.
It makes no sense to use average during whole day (or a month), as you do the capacity management to avoid business impact due to link utilization; and average does not help you to catch is the end-users experience any performance issues.
Typically your capacity management algorithm/thresholds are dependent on traffic patterns. As theses are really different cases if you run SAP+VoIP vs. youtube+Outlook. If you have any business critical traffic, you need to deploy QoS (unless you are allowed to increase link bandwidth infinitely).
So, I would recommend to use 95-percentile of maximum values on 5-15 minutes interval (your algorithm/thresholds will be really sensitive to pooling interval, so choose it carefully). After to collect baseline (for a month or so) - go and ask users about their experience and try to correlate poor experience with traffic bursts. This would help you to define thresholds for link upgrade triggers.
PS: proactive capacity management includes link planning for new sites and their impact on existing links (in HQ and other spoke).
PS2: also I would recommend to separately track utilization during business hours (business traffic) and non-business (service or backup traffic).

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 .

Purchase Requistion,Purchase Enquiry, Sales Enquiry,Capacity Planning & Sch

Hi All,
I am working in SAP business One for quiet long time as Functional Consultant and i am very much aware with its design. And Now SAP is bringing SAP HANA also for Mid Size Company or you can say in SAP Business One.
BUT ...............
In any industry vertical there is always requirement of Purchase Requistion (Department Wise) , Purchase Enquiry and sales enquiry is Must to buy or sell the Item.
Why dont SAP is providing three different FORMS like sales Quotation , (Sales Enquiry) , Purchase Quotation (Purchase Enquiry) and Material Indent or Purchase Requisition (Dept. Wise) This i am spcifically asking just because the requestor doesn't knnow the Suppliers Name.
And This functionality is in SAP ECC .
This will reduce ADD ON
MRP is enhanced so beautifully in Latest Version but only Capacity Planning & Sceduling is Missing.
Capacity Planing and Sceduling if possible then I think Maximum Industry accross the World will consider SAP Business One
I hope by this forum i am Just Pointing this. So that we can get in near future
If anyone gets any clue on this please let me know.
Please Join hands if this feature what i discussed is really required .
Thanks & Regards
Ashish Gupte

Hello Friend,
I am very much agree with your suggestion
But every one know that ECC is not for SMB sector so it is full flesh ERP compare SAP Business one and may be these form will part of SAP business one road map.
Because SAP has added some rich process for MRP but after get suggestion from form and these link form http://forums.sdn.sap.com/forum.jspa?forumID=265&start=0
and these given above link also is a good place for your question

Capacity planning (performance tuning of WLP 8.1 SP6 application)

Hi Guys,
I have one question regarding the performance tuning of the weblogic portal application (or may be any J2EE application for that matter) :
I understand that there could be lot of performance bottleneck areas e.g
(a) network issues (not enough bandwidth),
(b) bottleneck because of the DBs,
(c) application design/coding
(d) JVM might not have been tuned as per the business requirement of the application
(e) lack of clustering
(f) hardware problems (CPUs, RAMs etc)
Inorder to do the capacity planning for such an enterprise applications, what would be the best starting point?
Is it a good idea to start and profile the application using some profiling tools like OptimizeIt or JProbe? and then analyze the profiling the data and conclusion can be drawn interms of what and where the major bottleneck is into the application and accordingly it can be worked upon.
Or if there is any better and elegant way doing capacity planning?
Thanks for your time.
Regards
Jameel

Hi
id say start with a load tool that simulates average/ peak behavior with varied inputs and exercise your site . then profile if necessary.
Also start with the critical/most used portions of your site.
Its difficult doing the above because unles your migrating noone really knows the expected usage of your site. And its hard for someone to specify acceptable response times.

Capacity planning for inspection

Hi,
I would like to plan for capacity required to complete inspection lots at our labs. This should include inspection types for 01, 03, 04 and 08. Is there a way I can do this in SAP ? I am planning to use an enhancement and create a planned order for every inspection lot (1:1 relation). But I don't know how that will work. Does anyone have any ideas ?
Thanks

Hi GS,
I think that's a good question, might not have been explored much.
I think, you can try to utilize the potential of "Quality Work Center" attached to inspection operations, and activate Machine and Labor as capacity categories, use relevant formulas and try the standard Capacity planning process for PP.
For more details, please go through the links -

Capacity Planning for Workflow Manager

Some information is available regarding highly available Workflow Manager implementations but I cannot find any information regarding when or how you should perform capacity planning for the workflow manager.
A few questions are jumping out at me.
When would we want/need a dedicated Workflow Manager server? (I can understand if this was shared between multiple farms this may be a benefit but what about from a pure capacity perspective).
Are there any case studies or documentation that we can use as a baseline estimation for capacity for the workflow manager?
Generally speaking for a small/medium farm deployment is it expected that this service also run on the application server?

@cory_peters

That would really depend on what kind of workflows are being run and the traffic being generated by the users. If you have long and complex workflows, you will need multiple nodes in the farm to handle.
Our tests with very simple workflows on a 16-core 16GB machine with SQL Server on a diff machine showed that it could handle 400 incoming messages per second and 65 workflow executed per second. Now if you have complex workflows, it may slow down further.
If you have one msg per user per second - it may mean 400 users handled per second. But I wouldn't make that conclusion - u must test your farms against your scale needs and accordingly plan your farm capacity
Hope this helps

Capacity Plan with Oracle 10g

Good Day to all,
I've little time working in environments with Oracle databases, I have requested to carry out a capacity plan with Oracle Database 10g for a data warehouse project that is leading the company in which they work. I request to make a plan specifying, among other things: size and number of tablespace and datafiles, projection growth taking into account the initial charge and the charge per week (incremental). The truth is a bit complicated for my inexperience in this kind of sizing requirements we will ask for your valuable cooperation. There are mathematical formulas that allow me to take those projections into account the type of data and their lengths? , There is a standard for creating the tablespace and datafiles?.
In advance thank you for your contributions.

The first thing you need to get management to do is give you two things.
1. The cost to the organization for downtime, rated in dollars/hour.
2. The service level agreement for the system's customers.
3. The amount of data to be loaded into the system and the retention time.
4. What version of RAID or what ASM redundancy is planned.
With that you can start at the grossest level which is planning for database + archived redo logs + online back files.
I generally figure the database, itself, at about 25% of required storage because I like to have at least two full backups, a bunch of incremental backups, plus all of the archived redo logs that support them. And all on separate shelves.
The number of tablespaces and data files is really just a question of maintenance. Ease of transport. Ease of movement. Ease of backing up.
If you want to get down to the actual sizes of tables and indexes the best place to go is the DBMS_SPACE built-in package. Play with these two procedures:
CREATE_TABLE_COST and CREATE_INDEX_COST which do the job far more efficiently and accurately than any formulas you will receive. You can find demos
of this capability here: http://www.morganslibrary.org/reference/dbms_space.html.

Capacity Planning Tool needed

Hi,
As a novice user, I have few questions. I would really appreciate any direction or help:
Q#1: Is there a capacity planning tool in Oracle Database that can tell us when do we need more memory or CPU?
Q#2: Is there a capacity planning tool in Oracle Database that can be used for sizing a new system?
Q#3: How do we find out the status/usage of CPU, Disk Usage etc?
This is the version in use: Oracle Database 11g Release 11.2.0.1.0 – 64bit Production
With the Real Application Clusters and Automatic Storage Management options.

Capacity planning of a farm.

One of the customer wants to try the SharePoint as Content Management & Collaboration solution. Customer has 225000 users, 10,000 active users daily. Users are across the global. I am working on Farm design. Since Customer is not sure whether they will
opt the SharePoint so I am thinking that I should purpose minimum infrastructure that can handle the load. Initially Farm wouldn't have more than 1 TB of documents. Enterprise Search will also be enabled.
Should I purpose single farm that will be accessed across the globe. I suppose this will not work since WAN latency between three continents might be the issue.

SOA - EAM capacity planning

I have been handed an assignment to prepare "capacity planning documentation" for what is termed "Enterprise Application Messaging"(EAM). I am looking at the documentation for Oracle Fusion Middleware and in particular Oracle® Fusion Middleware Installation Guide for Oracle WebLogic Server 12c Release 1 (12.1.1) which has some basic installation prerequisites. This is a good start but I know that there is more to capacity planning in the context of this EAM notion like for instance a database to persist messages etc and then there are the "speeds and feeds" to consider.
My question is: Are there any white papers, best practices or Open World presentations that are more current than the 10g documentation and presentations I have found on searching that would cast the Oracle Fusion middleware more in a "generic EAM context" than this 12 C product installation documentation I am looking at?

Thank you for the quick reply and the great links you gave, I am reviewing them before proceeding.
I agree, the EAM is a mysterious acronym...I'm not sure who dreamed it up, but to me, it means SOA and OSB and that is what we will be building in a new datacenter. I believe it may be a "home grown" acronym to try to keep from becoming too vendor oriented with our high level documentation...we have a bunch of Microsoft afecianados here who would like to place something like "Biztalk" into the mix, so maybe they got the powers to be to invent a more generic acronym.
Yes, I have also found that I need to look at the 11g not 12C docs due to certification issues, hopefully resolved in a couple of weeks I'm told.
There are some great diagrams you pointed me to and I sincerely appreciate your quick reply...thanks a million!

Rough Cut Capacity Planning

Hey all,
i wanted to configure Rough Cut Capacity Planning in such a way that
1. i could view capacities of workcenters given that the demand (load) of planned orders could be executed in a particular period.
I accomplished this partially, meaning i could find out the bottlenecks on the workcenters but this was only on single material level, if i wanted to run this check on multiple the system, supposedly, offers me the option of using the product group, my question is, where do i view these bottlenecks on capacity IF i want to run RCCP on Multiple products.
2. i wanted to find out exactly how much i can produce in a period, given that the external and internal procurement lead times are incorporated this is usually reffered to as Master Production Scheduling, as far as i know atleast.
kindly shed some light on these matters.
Regards,
Danish
PS. i've seen similar posts to this but none directly addressing these issues hence i felt the need to ask these questions seprately.

to further clarify my question i would like to see, as a result of stimulative planning (RCCP):
1. Impact of Planning (planned order quantities) from ALL materials that were being planned on work centers used in recipes.
2. Identification of bottlenecks, which is of course the subsequent function from point 1.
3. Capability to produce with reference to Materials availability (lead-times being incorporated of components).

Bandwith Capacity Planning for 100 user SSL VPN Facility

What are things we should conisde while doing the bandwidth capacity planning for SSL VPN Facility for 100 users ?

Hi Surya,
This is not an easy question, since there are so many things to consider that I may miss some of them.
1- In case you are planning to use an ASA, check this to find the ideal throughput for you:
         Compare Models
2- What type of traffic? TCP or UDP?
     If TCP
          Make sure you avoid fragmentation, adjust the MSS value if necessary.
     If UDP
          If fragmentation must happen, then set the DF bit to clear to allow it.
3- Make sure the clients always negotiate DTLS (which is by default).
As mentioned in the document above:
"Maximum throughput measured under ideal test conditions.
VPN throughput and sessions count depend on the ASA device configuration and VPN traffic patterns. These elements should be taken into consideration as part of your capacity planning."
Thanks.
Portu.
Please rate any post you find useful.

Charset and capacity planning
