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.

Capacity Planning Guide for OAS 9i

Hi all,
I really want to know about is :
"How much server/cpu/memory do I need to support n
number of users?"
So I can decide specification of server that I needed.
I've read technical white paper about 'Oracle
Developer Server 6.0 - A Capacity Planning Guide'
March 1999 and,
'Scalable Web Deployment with Oracle Developer Server
- A Benchmark Comparison of Client/Server and Web
Deployment by Retek Information Systems' November 1998
Is there other twp like that for OAS 9i ?
Regards
Yohanes

The document does not really give figures but more, the way you should plan to estimate your capacity - as such, the document is relevant for 10g as well as 6i

We need to do a capacity planning/sizing for DB

Can you please provide any template/suggestion for DB capacity planning

Dear dba,
Database capacity planning will be based on the volume of the data that you wanted to load to the database.
For instance you are planning to trace the performance on the fixed line circuits. Take some sample performance files from the vendors and see the files' sizes. According to those file sizes estimate the average load and see the SLA for the period that the files will be stored on the database.
I have never heard of any template or a suggestion methodology for database capacity planning rather than simple calculations like sum, multiply etc.
Can you please elaborate more and we may have some additional information on your concerns.
Regards.

JMS architecture question for fat client/server.

Hi. Is JMS suitable for fat client-server architecture where a certain number of fat client applications (like a few hundreds) open connections directly to the JMS provider? Is it going to have scalability problem when the number of connections grow?

Depending on your JMS provider, this may be a very suitable architecture. The Sun MQ JMS Cluster was architected exactly for this problem. If the number of connections onto a single broker becomes too much of a burden for this broker, it can be put into an MQ cluster and share the number of connections. Of course, the number of connections a broker can handle will be totally dependent on the resources available to it. OS, CPU, memory, other applications running on the same machine, etc....

Question for 11g OCA certifications

Hi All,
I completed the 1Z0-007: Intro to 9i SQL back in 2003 and never got round to completing the other cert exams.
My question is, is this exam still valid or would the first exam need to take place again? Do the exam reults expire?
I see it is still mentioned as as one of the exams you can complete for it.
Thanks for the help.
Stuart

Yes, you are very much eligible for writing OCA 11g Certification Exams. All you need to do is, while registering for OCA Exam, that show your Oracle 9i SQL Exam details to the Prometric center and other details when you passed that exam.
For more information on OCA/OCP 11g Exams take a look at the below URL.

Hardware question for OS X Server

Hello all,
I am new to MAC's and still learning so I have what may be a dumb question.
I have at my disposal 3 Dell PowerEdge servers that I can combine to make one really powerful workhorse. My boss is wanting to migrate all of our PC users to MAC's over time. I would like to install OS X 10.4 Server and start using this as our primary domain for those already migrated.
My question.......is this possible?
Can I use pc hardware to run OS X 10.4 server?
(assuming I use a 10.4 tiger MACbook to format and install the initial harddrive that will run the server? I di dread those posts about the 10.4 version dependency.)
thanks for everyone's help in advance...

>ok, but can you tell me why and has anyone ever tried?
For numerous reasons. For one, Apple have numerous checks in the OS for components that are not part of a standard PC motherboard. There was talk of Apple implementing TPM to control the hardware, but I don't know if this really is the case.
Secondly, Macs use EFI and Open Firmware as the boot loader. PCs (at least Windows) uses BIOS. The BIOS system can't load a Mac OS X system.
Thirdly, even if you could get past that part you're going to run into driver issues. Since Apple provide the hardware, they can bundle the relevant drivers with the OS.
That said, there have been some reports of some people having some success in getting Mac OS X to boot on non-Apple hardware, but always with some limitations (e.g. can't get past the Finder), and it's against Apple's license agreement so they're not likely to widely publicize the fact, anyway.

Family Plan Question for iPhone 3G

My brother and I share a family plan together. He already has a first generation iPhone on the account and I am getting the 3G iphone when is comes out.
Will our plan go up 30 dollars when I get the iPhone setup or will it go up just 10 dollars for me adding the 3g data price on the account?
This probably didn't make any sense lol, but any help would be appreciated!
Thanks,
Brendan

Info I've been getting from ATT:
2g(original) remains 20 bucks for data and 200 text message
3g add 30 dollars to account and if you want text - 5 bucks for 200 messages.
10 dollars more would be only if you upgraded to 3g and gave away old iphone.
since you're keeping 2 iphones to account you need data for each iphone and its corresponding data plan. You will renew a 2 year contract with att for 3g and if eligible for upgrade you pay discount price and 18 dollars upgrade fee to appear next bill !

Query Plan Question for Outer Join

I have the following join query:
select unique ep.ACT_UID,
ep.SE_REQ_TS,
sr.SERVICE_NM
from
eaisvcs.Service_requests sr,
eaisvcs.SERVICE_EPISODE ep
where
ep.ACT_UID = sr.ACT_UID;
I have an index on the act_uid in both tables, and the statistics are up-to-date. There are about 3.2 million rows in each table. 10% of the act_uid's that are in the ep table that do not have a match in the sr table. Other than that, most id's match up between the tables.
Here is the query plan:
ID PARENT_ID OPERATION OPTIONS
0 SELECT STATEMENT
1 0 SORT UNIQUE
2 1 MERGE JOIN
3 2 SORT JOIN
4 3 TABLE ACCESS FULL
5 2 SORT JOIN
6 5 TABLE ACCESS FULL
I cannot figure out why a table scan is being performed every time on both tables. The Act_UID is the PK in the ep table. There is a composite index (act_uid, sev_seq_no) in the sr table. the act_id is a varchar2 column in both tables. The sev_seq_no column is numeric.
Any ideas or insights about this would be greatly appreciated.
Thanks!

The plan can be good.
Oracle choose a full table scan for these reason too:
- sr.SERVICE_NM is not a part of the index and so a full table scan is less expensive. If you will add this field to your composite index Oracle will probably take this new index.

Capacity planning considerations for low volume iPad Policy Management

We're looking at placing a Mac mini in the DMZ for the sole purpose of providing remote iPad (only) enrollment services and policy management/enforcement. We have a pool of about 15 iPads with more trickling in here and there - nothing dramatic...
I know this is somewhat of a subjective call but how much horsepower would you recommend between the apparent $560.00 to $2k+ price range for Mac Mini's. We don't expect a lot of churn in the enforcement/policy management realm once the devices are enrolled. Yes, I am aware that Mac Mini's aren't necessary intended for use outside of the home (in corporate environments) but my guess is that a Mac Pro is overkill for the intended purpose...
Any all opinions, considerations welcome and thanks...

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:

How to go about capacity planning for storage ?

Hi Experts,
How to go about Capacity Planning? For instance if clients wants to upgrade to new server and new storage and asks us how much additional storage do you need for next 5 years, how can calculate the amount of storage.
I don't have any baseline info about the server of past years. Where can I start and any scripts you guys use for doing capacity planning?
Appreciate your help.
Thank you.

Capacity sizing document for Forms on iAS(Oracle Application Server)

Hi,
I need to know from where I can get Capacity planning document for Forms on Oracle Application Server for Intel/Solaris/Aix arch.Please Advise.
Regards,
Noman

Hi,
we have several developers working with developer suite 10g. Our OAS runs on Linux as yours. All our developers work locally using windows-pc's. We have a samba share we use to move the developed sources to the linux box. On the linux box with have some scirpts to compile the sources and move them to the runtime-directory.
The final integration test in then done using the installed application on the oas.
This works without having any problems for more two years now.
btw: Be aware of the problems you will run into when moving an application from windows to linux:
-> All filename ar Case-sensitive
-> the writing of module-names in OPEN_FORM, NEW_FORM, CALL_FORM must match exactly the filename (in other words: call_form, open_form and new_form is also case-sensitive
-> Attached librarys are also case-sensitive, even if there are shown in uppercase in the module-navigator.
hope this helps.

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 -
1. http://scn.sap.com/community/erp/manufacturing-pp/blog/2013/10/23/capacity-planning-or-scheduling-leveling-maybe-sequencing
2. Capacity planning - ERP Operations - SCN Wiki
3. Capacity Planning (PP-CRP) - SAP Library
4. http://scn.sap.com/docs/DOC-49431
Please do further search on this subject and work with PP consultant to use this functionality. Finally share your results once you are done
Thanks,

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!
