Database sizing

Hi,
We have a production machine estimated by client for hosting an application. The configuration is
12 CPU
32 GB Ram
512 GB hard disk..
What is the maximum database size the machine can host with good performance.
What are the maximum number of instances the machine can host with optimum performance.
What are the maximum number of databases recommended ?
What is the maximum size ( number of records ) in a table the machine can host and provide a reasonable response for a select * query on indexed columns with less than 10s
We are expecting a table/ set of tables to have 3 billion records. What is the best way to host these, ( splitting into multiple drives, having of indexes in seperate drives) ?

The answer to all these questions is going to be "it depends". It depends on data volume, query patterns, user volume, database design, I/O throughput, etc. You may be able to run a dozen databases on this machine with no problem, you may find that a single poorly designed database can bring it to its knees.
For handling very large data sets, you'll definitely want to consider partitioning (an extra cost option for your enterprise edition license), materialized views, and other data warehousing features.

CRM TPM Database Sizing for CRM and BW

All,
I am currently sizing for a TPM implementation and have a couple of questions concerning storage capacity for CRM and BW. I have reviewed and created an Excel spreadsheet based on the SAP Sizing Guide for CRM-TPM but I am coming up short in a couple areas.
Here is the document Link: [https://websmp105.sap-ag.de/~form/sapnet?_FRAME=CONTAINER&_OBJECT=011000358700000711312004E]
1. Is there a storage sizing guide for BW or what has worked for the community to estimate?
2. Is the sizing guide for CRM/TPM correct (see below example)?
3. What has worked for CRM/TPM database sizing from the community?
I have a question about section 3.3.3 Disk Sizing in CRM. If the disk sizing is based on per promotion (for the condition generation process), why is there a multiplication factor for PARTNERS? I donu2019t believe we would have more than 1 or 2 partners per promotion.
I did some quick math with some example numbers and came up with about 2.9TB for the CRM database. See below for additional info based on the equation in section 3.3.3.
Part 1
20,000 Promotions
10 Products
1000 Partners
.87TB
Part 2
10,000 Promotions
47 Products
1000 Partners
2.04TB
Is this accurate for sizing the condition generation process for the CRM database? I am failing to understand why, for example, the 20,000 promotions would have 1,200 partners included in the base equation for each promotion.
I appreciate any time you could spend in responding to my question.
Thanks in advance,
Steve

APEX database sizing methods and spreadsheets

APEX database sizing methods and spreadsheets

Yes I asking how much space the APEX 3.2 framework requires as well as yes to how much space to allocate for your particular application that happens to be implemented in APEX. I have 1 word form that contains 10 fields that are filled in by users currenlty now. So far, I have 50 of these completed (same form) and would like to create an APEX application supported by a database that can initially contain this data in one table once migrated and be able to hold more of this data as the new online system is used. Therefore, are any sizing methods, for example, function points or excel macros, etc...that can be used to predict potential database sizes needed based on an increase in data volume.
I ask this because currently APEX 3.2 uses Oracle Database Express Edition (XE). Oracle Database XE can address only 1GB of RAM. This limitation mainly affects how many users can access the database concurrently and how well it perform but APEX can run against a full 10g or 11g install of Database as well as XE, and you can upgrade rather nicely from XE to full DB if your needs demand

Need to database sizing

Hi ,
Can any one help me to know, how to do database sizing for oracle database.
If database sizing is differed from version than i want to know for 9i,10g and 11.5.10.2 application.
I dont have basic knowledge for doing database sizing. please tell me know because i have assigned a project on this in my company?
Thanks a lot in advance

The version of the database is irrelevant. Sizing is solely a function of the application.
In your case, since you have one or more applications in the Oracle eBusiness Suite, there is almost certainly a sizing spreadsheet floating around. If you post this question over in the forum for the particular application(s) you are using, someone over there may be able to give you some pointers. I would also strongly suspect that a Metalink search that included the particular application(s) you're using would be beneficial.

Oracle Database sizing spreadsheet

Hello Guys:
I am badly in need of the database sizing template for one of the projects. Can any one share a copy?
Regards,
BMP

Lets see what's missing:
1. A product name
2. A product edition and version
3. Any indication of how the database will be used ...for example the name of an application
4. Business rules related to the storage of archived redo logs, flashback logs, and backups
5. etc. etc. etc.
None of which is contained in any spreadsheet I have ever seen.
I suspect what you are referring to is the old Oracle Financials version 10 spreadsheet which I have not seen in a decade.

Lifecycle Workflow platform and database sizing guide?

I've been asked to investigate the technical aspects of the Lifecycle Workflow and Reader Extension products.
I've gone through the various adobe websites a great deal and found installation guides but nothing that provides platform selection and database sizing recommendations.
We are considering both JBoss on Suse LInux and WebSphere on AIX as a platform.
Is anyone aware of any recommendations as to the choice of a platform?
Any experiences or recommendations out there from the user community?
Also, is there any documentation that gives guidance to database sizing? Frankly, I'm not sure I understand yet whether it's just the routing/metadata that gets stored in the workflow database or the actual documents as well.
Anyone point me at or provide me more technical documentation?
Thanks
Verlyn

Hi Verlyn
I can answer some of your questions, based on my understanding.
The workflow engine does store the document itself as part of the workflow. In fact, it records the historical state of the document at each point that someone in the workflow worked on it. You can see this by looking at the "Participated" item in Form Manager, where you can see the historical value of each form that's been submitted. Any workflow attachments are also stored in the database.
It gets a little more complicated. Depending on how you structure your workflow, you can choose to either store the entire PDF (in a document or binary variable) or just the data (in a form variable -in which case the data is merged with an xdp template whenever someone wants to view it).
Document variables are also a little more intelligent: you can specify a size threshold. Below that threshold, the document is stored as a blob in the database - above the threshold, the document is stored in a folder on the file system. The default threshold value is 64K.
I hope this helps...

Database sizing and also storing in AD?

Hi All,
I'm just spec'ing out an MBAM 2.0 design for our Win 8.1 deployments and wanted to just check a few things.
1. Are there any issues to storing the recovery key in AD (as we do currently with W7) as well as in the MBAM database? Other threads seems to suggest that it's fine.
2. Database sizing. I've seen figures of approx. 250mb per 10k clients. Does that seem fair and is that for each database (ie. recovery & audit databases, therefore 500mb per 10k clients)?
3. Our SQL team suggested putting the SSRS onto the Admin & Monitoring server. Is that a supported configuration or a big no-no due to security? Or does it use the SSRS of the CM server?
Also it might be worth noting that this will be integrated with CM12. We have a CAS with a number of primaries, so I was presuming to install it on the CAS.
Thanks in advance.
Simon

1.) Not that I have seen. I have done this in the past without issue
2.) From what I have encountered that seems like a fair estamation. I believe if you have a more frequent or less frequent check back to the server, you may have a slightly bigger or smaller DB size
3.) I'm not sure if it's supported. Is there a reason you guys particularly want SSRS? I'm sure you could use SSRS to generate your own reports but the console allows you to generate some canned report and I don't beleive this uses SSRS to do that.

Database Sizing for Oracle Applications 11i

Hi,
I was wondering if someone could guide me on how to size an oracle applications database, we'll be using the following modules: GL,AP,CE,FA.
The operating system, might be windows 2000.
What I have in my mind right now regarding the information i need to collect is as follows:
1. No. of users
2. Estimated transaction activity for the above modules, and whether month
end's are particularly transaction intensive.
And yeah thats how far ive gotten , hence the help needed.
About the transaction activity, how do i really quantify it and then translate it into something meaningful that will help me in sizing the database. Could I perhaps get information regarding how many transactions an average user enters in a day ????
Well basically any sort of input would be really helpful, thanks in advance.
NM

Need to know the number of users as we can guess at the transactions level.
Some base line assumptions.
1. You need 1 Gybte of memory before you add any users.
2. You need 10 Gbytes of disc, to hold the SGA, UNIX, Swap Space, Application etc.

Re: Database Sizing

Good Afternoon,
I hope this is the correct place to pose this question. If not, please advise on the correct forum.
I guess for all intensive purposes, you could consider me a Junior DBA. I guess when most people got word that I could spell SQL and had gone to a few Oracle classes, they assumed that I was a seasoned DBA.
I am just about to wrap up phase 1 of a pretty intensive project on database backup and recovery. I'd had a GREAT mentor and have had fun overall. Getting to the point...my question is, how does a DBA know how to size a brand new database (i.e size the datafiles)?
If someone comes into my cube and says "Hey...I need a database". What kinds of questions should I ask? Are there any algorithms, scripts, or documentation that exists that I can use? I'm assuming I should ask for the ERD. I have no clue here.
Does anyone have a checklist or procedure that they use when creating/sizing databases?
Thanks,
Des

Catalog database sizing questions

Hi There,
We need to create an RMAN catalog that would be able to support 8 databases 5 of which are around 50gb(40GB db files+10gb arcglogs) and the remaing 3 are about 120gb (100 db files and 20 archlogs).
Does anyone have any sizing recommendations regarding memory structures (sga, pga, large pool)? disk space? We are using Oracle 11.1.0.7 on windows 2008 server. The server itself is an intel box, dual core E5440 - with 16gb RAM.
Thanks

Hi rsar001,
The size of the catalog schema and database in your setup will not grow to more than 1GB (as long as you maintain a retention policy).
Just set sga_target to 1G.
As an example I have around 100 databases with sizes bewteen 10 GB and 2T and run a daily backup on all of them retention policy 1 month.
The catalog is and stays around 700M for more than 2 years.
Rgds,
Tycho

Database Sizing Question for 11i

I am looking to see if there is a spreadsheet or tool that would tell me the optimal database size, for 11i.
I understand there was one for 11 that would tell you the best size after you told it the number of suppliers you have, the number of inventory items available, number of accounts, etc...
Thanks
Sanjay

Stefan,
I guess both of us were writing at the same time and hence I missed your post edited part. Let me explain the user part. You can think about them in 3 different roles:
Named users - Number of users in the system which may or may not have "Guest" users. Not much useful for hardware sizing.
Logged On Users - Users currently logged on to the system not yet logged off and user logged on to the system but killed the browser. But they are still in the J2EE system holding memory with session info. They are useful for Memory sizing.
"Active Users" - They are doing sometime with some "think-time". They could be "high/medium/low" users based on the "think-time". They contribute to both CPU and Memory sizing.
Based on the above definitions (which may vary with different models) sizing will vary. Once you know your user profile (how many of them and how they use), you can use quicksizer to have some initial estimate. In case you have access to SAP fields and/or support, you can contact for some additional information. Those are useful for initial stage. If you have your system available, run some load tests to verify your initial estimate and refine them.
Thanks,
Swapan

Estimation for database sizing

Hi,
I am looking for ways to arrive at estimate/calculate database size for our application. These are the details in brief.
All the tables are created under a user. The user is associated to a single tablespace.
Two kinds of data are stored. Config data and run time data.
Config data is stored in variants of varchar and clob. Run time data is stored in columns of datatype number(10).
Run time data is retained for specific period and then it is purged. Based on the deployment, the number of run time data points vary.
I am looking for something like this. Based on the number of data points collected, i want to arrive at the sizing requirements like require so much free space on the disk.
Can someone tell me where all the storage is taken up and how much. Some thing like
How much space is taken up by Number(10). How much additional storage is taken up by an index on a table, a primary key.
Does addtional storage need to be added for each table, view.
Which objects that are created and how much storage is allocated for it physically.
Please let me know.
Thanks,
Krishna

See if this could be useful..

CMS/Audit Database Sizing

Hello,
We are planing to deploy BOE 3.1 for about 3,00,000 users the OS is windows and CMS database would be SQL server 2008.
Any help would be appreciated to help me arrive at an estimation of the size for CMS and Audit database for these many users?
Thanks
Ranjit Krishnan

Hi Ranjit, it really depends on how many metrics you are auditing (in another word, the items on CMC that are checked for auditing). We have 20,000+ users in our system and I am auditing about 90% of the metrics. Our audit schema grows to 8-10 GB in about 3, 4 months.
Frankly, in this day and age, disk drives are cheap. So storage is not your main concern. Your concern should be the performance. When the audit schema gets too large, naturally, the query performance will decrease. Therefore, I have our DBA archived off the audit schema every 6 months to reduce the size. And you need to back up the log files as well. In another word, we only keep a 6-months history. If someone needs older information, we can bring them back from the archive for a one-off query.
This is something you must sit down with your DBA and come up with a strategy that makes sense for your organization. Every company has different need. So there is no cookie-cutter formula to handle this.
Hope this helps.
