Oracle Database capacity planning

Hello Team:
Does any one have a Capacity planning spread sheet for sizing the server Requirements? ( CPU,Memory etc )
Regards,
Bala

Thanks Justin. How do I size the Database server Hardware? Third party apps most cases come with a
recommendation for hardware. I am talking about a situation where we have to build a database based
on certain basic inputs such as Concurrent users, Load , response time etc etc.Craig Shallahamer's orapub site would be a good place to have a look.

Can anybody give me the formula for Database capacity planning for 10gR2?

Hi ,
I want to learn how to make database capacity planning for production in 10gR2. Here i need any formula to plan the capacity.
Can anybody help me?
Regards
Rajesh

hi,
There is no perfect world. There is no perfect application. If I am permitted to say, there is no perfect CAPACITY PLANNING. In this world, we strive hard to achieve near PERFECTION
DISK SPACE ESTIMATED FOR THE DATABASE(RDBMS) ONLY
ESTIMATES ARE BASED ON ASSUMPTIONS, SAMPLING, STATISTICS
ESTIMATES CAN NOT QUANTIFY DISK SPACE REQUIREMENTS IN REAL TIME
ACTUALS ALWAYS VARY FROM ESTIMATES.
so ther is no particular formula to plan capacity planning.
or post your rquirements for the DB and wait for some reply

Database Capacity Planning

When procurring for new Hardware how to measure CPU & Memory consuming for 100 Users logging into the database.
Is there any guidelines to measure ?
For one user minium memory would consume ?

Hi,
It depends on what those 100 users will do. For example - if there would be high concurrency (all 100 connect at the same time and keep executing the SQL statements) there would be high CPU and Memory requirements.
If you are sizing for a new system, consider look at the statistics from test systems, otherwise you can collect statistics from the existing database (workload metrics from awr/statspack schema tables and CPU, memory utilization) and do the predictive modelling for forecast the additional hardware requirements.

ShadowProtect to backup Oracle Databases

Hi to all
I would like to hear from anyone if you are using ShadowProtect to backup your Oracle databases.
What are your experiences and the pros and cons in using ShadowProtect as the one and only backup/recovery tools for Oracle databases?
Can the potential of ShadowProtect replaces the commonly use Oracle backup/recovery tools?
The reason why I raise this question is because my boss has the idea that ShadowProtect is THE best backup/recovery tools. Personally I don't think so, because there can be cases where we only need to recover the database and not the whole OS. Thus need to hear more from you guys.
Thanks.

Hey Moslee,
You should definitely be testing your Oracle database recovery plan quarterly. If you're not even testing it annually that would be what really scares me the most. Testing should show you what you can and cannot get out of your backup and recovery software. Everything else being equal, please please please test your backup and recovery plan and do it often.
As for ShadowProtect, one of the nice things about this backup solution is that it's an image-based backup which means that it will quiesce the Oracle database and transactions to get a good snapshot of your database. Then (because it's an image-based solution) you can recover the Oracle DB, OS, installed applications, running services, data, and etc to that specific recovery point. Another nice thing is that ShadowProtect can quickly virtualize a backup image as a VM using Oracle's VirtualBox, MS Hyper-V, VMware, Citrix ZenServer and/or RedHat's KVM. Over all ShadowProtect's a pretty powerful and easy to use Windows backup tool.
Oh, and ShadowProtect's integrated with Oracle's VirtualBox technology (it's called ShadowProtect VirtualBoot) which makes it SUPER easy to spin up a backup image as a VM and verify (read "TEST" in capital letters) whether you've got a solid backup of your Oracle DB. I'd hate to find out the day after the excrement/fan fiasco that my backups were unusable. Please test! (I'm cringing in my chair here.) Then let us know whether you agree with your boss.
Cheers!

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.

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.

Oracle Performance Forecasting / Capacity Planning

Hi,
I am being told to Analyse and Propose the Oracle Performance Forecasting / Capacity Planning, since our database are being hosted on co-hosting services. By planning we can help the cost of CPU, Memory and Disk projection.
Is there any way, we can get the current workload from the current production environment, and calculate the forecast based on Statistical values.
I know, we can get the current workload from AWR, but I dont know the calculations and proper judging method.
Thanks in advance.

If your application is typical, it will consumer resources in rough proportion to the load in transactions/queries per second. If your business is stagnant, the resources consumed will stay about the same.
As load grows, though, you'll hit a point at which the response time starts to grow without bound. This is typical of growing businesses, or ones which have done acquisitions in order to improve their customer base.
Capacity planning is knowing where that point is, and planning to stay far away from it (:-))
If you can do a load test on a single instance of a cloud (or time-sharing) machine and replay previously recorded transactions, you can measure how many replayed users it will take to slow down the machine, and how many additional user it takes to bring the transaction time from a typical 2-3 seconds to 30.
If you plot that line, you'll find you have a hyperbola or "hockey-stick" curve, and that will allow you and your financial mangers to plan on exactly how many users to cap a given machine at, to keep the performance below 3 seconds or so. After that many users, add another machine.
The usual rule of thumb is to keep the response time from doubling from it's average at very low load, as after it's once doubled, it keeps doubling and redoubling with tiny increases in load.
I personally like to model first and stress-test only to confirm I've not messed up. The tool of choice is Teamquest Model, and have used it to accurately measure and predict the behaviour of an Oracle database (and lots of other stuff). If you're interested in the theory behind this, read anything by Neil Gunther...

Capacity planning of database objects

Oracle 10.2.0.4
Windows platform
I was reading Oracle Admin Guide :- Capacity planning of database objects section, but these and most of other sections are very theoretical .
Kindly suggest how to get these topics in better way.

I think Reddy has it right: watch the trend in space usage primarily at the tablespace level but you would also want to take a look at the individual tables and indexes within a tablespace to spot the fast growers, to pick out tables that might need parameter adjustment (pct_free) to avoid row migration, to identify indexes that may not reach a reasonable stready state size, etc....
The dba_outstanding_alerts and related views might be of interest.
On occassion just taking a count(*) of how many application tables, indexes, and users exist on your system and storing this with space usage figures can also be useful information when it comes time to request more disk, cpu, or memory since you can show past growth.

Oracle VM documents (perf tuning, monitoring, metrics, capacity planning)

Hi,
Does anyone has any document on Oracle VM performance tuning, capacity planing and monitoring.
I have Oracle VM environment with two virtual domains, each has one Oracle database running. I have been asked to monitor performance, identify performance metrics at OS/VM level (for memory, cpu, IO). If required, estimate additional hardware (Capacity Planning).
Thanks,
Neeraj

Without sar utility (sysstat RPM, i'm pretty sure it is not included in OracleVM) you are pretty out of luck. As OracleVM is based on OEL5 you could try to install sysstat RPM from OEL5.

DBA Cockpit: Planning calendar and remote Oracle databases- which method?

For using DBA Planning Calendar to schedule BR*Tools for remote Oracle database AS Java systems I have successfully implemented both the Secure Shell and SAP gateway methods in [Note 1025707 - DBA Cockpit: Planning calendar and remote Oracle databases|https://service.sap.com/sap/support/notes/1025707] and was interested in which of these two methods others have found to be more supportable and maintainable?
In more detail, the note has these two methods for non-ABAP remote systems:
2. Connection through Remote/Secure Shell
Specifically Secure Shell. Rejecting remote shell as too old and insecure a protocol.
3 Connection through SAP gateway
The note provides clues as to how these methods work. Expanding on that:
With #2, central ABAP system calls out to its OS user level to execute the ssh client (after gw/rem_start has been set to the non-default value SSH_SHELL) which it finds in the location specified in gw/ssh (default value is /usr/bin/ssh). It must use password-less authentication and the key-based authentication must also not require a passphrase. (Using ssh-agent is not an option since this is being called from SAP, not from your own script.)
It remotely runs via ssh a command, sapxpg, which must be found in the PATH of the remote user. (This is why the note, which has you place this exe sapxpg and a subset of the BR*Tools in the home dir of the remote user, also has you make sure the home dir is included in the path--your OS might or might not include the user's home dir in the path in the default shell environment for a new user.)
Then via sapxpg, the BR*Tools are invoked.
One thing that may be confusing here is you have to check at least one gateway parameter 'gw/...' in the central system to get the method #2 the non-gateway method to work--this is because the two methods are technically almost the same: in #2, secure shell is used to basically start a gateway on the fly with sapxpg in order to call the BR*Tools each time a DBA Planning Calendar action runs or you view DBA or Backup logs of the remote system from the central system. With #3, the gateway runs continuously on the remote system.
With #3, central system connects to remote SAP standalone gateway, which executes the BR*Tools installed in the standard SAP kernel directory of the SAP gateway. This method is simpler to describe so it sounds like it has less components than the secure shell method, however you do have an entire SAP system running, although it is just a standalone gateway.
Thoughts:
These pros/cons are UNIX/Linux-oriented since I assume most Windows environments do not have added 3rd-party products that provide secure shell so SAP gateway is the only method.
Secure shell
+ Less software required (not counting secure shell which comes with the operating system distribution): just a few SAP executables placed in the home dir of an ordinary user on the remote system.
+ Secure shell service probably automatically starts upon boot of the remote system operating system.
+ Secure shell is a widely used tool outside of SAP for executing commands remotely without passwords.
- Installation is non-standard: shell environment of remote user is not adapted by SAP installer since SAP installer is not used, SAP executables in the home dir of the remote user is non-standard. Has to be setup manually.
- Requires setting up secure shell key-based authentication, which should be known by UNIX/Linux admins or combined Basis/UNIX/Linux admins, but might be less familiar to SAP Web AS only admins.
- If your admin config policy is to have SAP interact as little possible with the OS level for interfaces with other systems, here you are relying on the OS-level secure shell.
- Using a private key that does not require a passphrase on the central system may not fit with your security policies if you have standards for secure shell configuration.
SAP gateway
+ The gateway is a standard installation, performed with SAP installation tool, with the exception of a few additional environment settings that have to be added after the installation. BR*Tools are installed in the standard location. Can use standard procedures for updating this software.
+ Only uses SAP software.
- More software on remote system: standalone gateway just to run BR*Tools and view logs.
- SAP Kernel of remote gateway should probably be updated whenever you do SAP kernel updates across your systems for consistency. One more system to update.
- Shell environment of remote user that runs the gateway looks like something setup by the SAP installer but is not standard because it has a few additional environment variables added.
- Need to make sure the SAP gateway is started on the remote system.

Hi Joe,
I configured a monitoring/dba landscape for two SAP Portals and one SAP BusinessObjects system on a SAP landscape by using DBACOCKPIT, at a customer site. These systems are running on AIX, Windows 2003/2008 servers and attached to the central monitoring system with standalone SAP gateway installations.
One another reason to not use OS based commands or 3rd party tools is security. We are stopping and disabling most of the services on OS where SAP system is running on, because of the security reasons. I faced more security gaps on rsh/ssh and the other tools than standalone SAP Gateway installations. As you can figure out that rsh/ssh is getting more attack than standalone SAP Gateway, because of well known by the IT world.
As a summary of it, this depends to point of view and policy of the IT organization. I applied both ssh and standalone SAP Gateway solutions at my customers, but I choose standalone SAP Gateway installation among of them.
Best regards,
Orkun Gedik

Oracle Database: productivity increase

Hi all,
in our company we use the three-tier architecture base on Oracle products:
client(web browser) - application server (Oracle AS 10g) - database server (Oracle database 10g).
and we plan to appreciably increase number of clients. And it is necessary for me to define how much it will be necessary to increase hardware units productivity (CPU speed in MHz and RAM capacity in MB) to support new clients on Oracle AS 10g and Oracle Database 10g side.
I've found AS Discoverer Sizing Calculator on oracle.com, but I can't find similar calculator for Database 10g.
Could anybody please advise how to calculate hardware sizing for Oracle Database 10g server?
Thanks a lot

Again - as the question you asked about the bandwidth - this cannot be answered without knowing the application, number of users, amount of data, etc.
I suggest you build an environment for a POC/Benchmark.
In this environment you can install your application and tweak the settings (various initialization parameters, etc) to see the impact on your system. Be sure to include enough data as most systems work well with 1 MB of test data but not with 5 GB of test data.
