Number of Oracle Users

In an application ther are 2000 valid users. Does it make sense to create so many oracle users. does it affect performance. I would like to make these users as i get better control over their activities and can customise their environment etc. But I am not aware of the downfalls of having so many users ? Is is normal for large apps to have so many users ? It is a net based app connecting field personnel of a company.

Hi,
I feel there is no probs in u having so many users in your database.
This will in no way affect the performance of the table.

Need help on exporting oracle users

Hi,
we currently on oracle ver. 7.3.3 with quite a number of oracle users created. We are in the midst of migrating over to Oracle ver. 8.1.7. We want to preserve the user details, so we don't have to recreate all of them again.
How do I export the users from ver. 7.3.3 over to ver. 8.1.7, preserving the user passwords, profiles, rights, etc?
Any help would be appreciated.
Thanks.

Hi Mr. Hian,
Take a Full database export from 7.x by connecting as SYS user (with FULL=Y) and import in the same in 8.1.7. Only thing u need to do here is to create all the required tablespaces(tablespaces used in 7.1.x DB) in 8.1.7 DB before importing the Db.
Hope this helps,
regds,

How to analyze the navigation flow in Oracle Portal, Number of unique users, downloads and other estastisticas of use of the Portal and Documents

Dear
Experts, I have a very exciting demand, the board of a customer.
I need to create an analytical application on Oracle Portal, UCM, Spaces, WebCenter, to inform me which quantitatively pages, url and documents are accessed.
How to analyze the navigation flow in Oracle Portal, Number of unique users, downloads and other estastisticas of use of the Portal and Documents?
I thought I'd create a ods with the data of Content Tracker and Google Analytics, and model the analysis through the BIEE.
I ask, what is the standard solution that is used in these cases?
Thank you

You mean ACTIVE users ??
Use following script :
active.sql
set pagesize 120
set linesize 150
select username, count(*) from v$session where status = 'ACTIVE'
group by username;
column spid format a5
column sid format 9999

Where to find number of concurrent users in 10g OEM

I have recelntly installed an instance in oracle 10g release2 rdbms.Is this possible to find the number of concurrent users in OEM.If yes please show me the steps.

The number of concurrent users can be limited by the SESSION initialization parameter.
But it can also be limited by insufficient or misused resources. It is possible to set the system to permit 30,000 concurrent users (per your post in the Installattion forum) and go into heavy swapping or paging, causing the system to not accept the required number of users.
A lot depends on the real load characteristics you expect - you may want to consider shared server or RAC configuration for certain load types.
My instinct is to have very careful planning sessions, with several experienced Oracle DBAs and developers, around the instance configuration.

Which is better? Two Oracle user in one instance OR in two instances?

Which is better?
I could not find any benchmark for number of instances per user
in the same machine.
suppose that you have two major Oracle user, from performance
point of view it is better to make separate instances in same
machine or keep these two users in the same instance.

Hi.
I understand that you will use oracle for two different
applications on the same host.
Each instance has its SGA and background processes. So, using
two different schemas(users) in one instance you can share
phisical memory between the applications. Concerning background
processes, you can start as many of them as you wish, so it's
not a problem. If you decided that one DBW is not enough, you
could configure oracle to use two or more.

Creating 500 or 1000 or even greater number of db users....

Hi ,
I have a huge system consisting of about 2500 tables and 5500 objects(total number including tables).
All these objects are contained in one single data schema - let's say dataschema A.
The requirement is to register almost every move (insert , update , delete , select) each user does.
All end-users (application users) are connected to their specific dataschema and using global synonyms are getting/inserting/updating/deleting rows to the dataschema A.
I haven't built my one auditing system to register everything , but i rely on the Oracle's one.....This would be somehow impossible to do it now as my application (Oracle Forms) consists of about 1500 forms....
My question is:
Is there any other solution to fullfill my requirement , except using the Oracle Audit system...????
My doubt is if the great number of application users -----> database users(1000 or even greater) will cause a great overhead to performance database....?????
Is there any other solution much 'cheaper' ...????
NOTE: The dataschema will not contain any db object ...
I use Oracle 10g v.2 RDBMS.
Thanks , a lot
Simon

My doubt is if the great number of application users -----> database users(1000 or even greater) will cause a great overhead to performance database....?????My guess is even if you build a custom audit, you will still not be able to avoid the performance issue anyway. So, I suggest you the Oracle Audit way.

Max number of concurrent users?

I'm in the process of creating a web site with Cold Fusion and
Oracle. One concern involves the lack of web hosting services
that run Oracle on their servers. So, to get around this
problem, I was considering replicating an Oracle lite database
and putting it on an ISP's server. My thinking is that there
would be little need of DBA functions and I can run it on any
server I choose. But ....
1. Would Oracle 8i lite support a lot of concurrent users?
2. What other factors would I have to consider if I set it up
as a distributed DB ?
Any help on these thoughts would be greatly appreciated.

Maximum number of contemporary users

Hi Everybody,
in my company we're planning for a new "Portal & Wireless" installation, and we need to know how many contemporary users can be served by the system. We have a three-tier architecture, with two different servers for the middle-tier (IBM x342, with 2 intel Pentium III 1400 MHz processors and 2GBs Ram memory)load-balanced by a Radware machine, and with the infrastructure (DB, SSO & OID) installed on a 4 Ultra Spark 400 MHz processors system (4GBs Ram). Does someone know any sort of algorithm to get the maximum number of contemporary user? Otherwise, which way can I estimate that value? Do you know any 'enlightening' document about this issue?
Thanx!

There is no easy answer to this question. You may find this document interesting.
How your hardware performs will vary widely based upon what you run on it.
Estimating anything can be a complex and error-prone process, that's why it's an 'estimation' not a 'calculation'.
Primarily there are three approaches to sizing a portal implementation, these can be identified as:
Algorithm or Calculation based
An algorithm or process that accepts inputs from the customer (e.g. user count, page count, hits, latency, doc size etc) and attempts to deliver a processing requirement is probably the most commonly accepted tool for delivering sizing estimations.
Unfortunately this approach is also the most inaccurate.
When considering a logical n-tier enterprise class portal implementation the number of variables involved in delivering a calculation that even approaches a realistic sizing response would require input values numbering in excess of one hundred, and calculations so complex and sensitive that providing an input value plus or minus 1% of the correct value would result in wildly inaccurate results.
The other approach to calculation based solutions would be to simplify the calculation to the point where it was simple to understand and simple to use. Unfortunately the sizing results delivered from this approach would also be wildly inaccurate.
Size-by-Example based
A size-by-example (SBE) approach requires a set of known samples that may be used as data-points along the thermometer of system size. The more examples available for SBE the more accurate the intended implementation will be. Asking a customer how many users they will have, what those usage patterns are likely to be and what type of content they intend to deploy on the portal are all questions that they should be able to answer. Asking them the likely cache-hit-ratio for a portlet is probably something they won't be able to answer unless you're asking the right people. Normally in a pre-sales situation the customer will not know the answers to questions like that. Those are the types of questions that would be required for the algorithm approach.
Oracle has the ability to deliver targeted SBE sizing solutions for our prospective portal customers through reference implementation documents that outline both our internal deployments and customer's external deployments.
By using these real world examples both customers and Oracle can be assured that the configurations being proposed have been implemented before and will provide the performance and functionality unique to the proposed implementation.
Proof of Concept based
A proof of concept (POC) or pilot based approach offers the most accurate sizing data of all three approaches.
A POC allows the customer to do the following :
Test their portal implementation design
Test their chosen hardware platform
Test their caching strategy
Simulate projected load
Validate design assumptions
Validate Oracle9iAS Portal
Provide iterative feedback for their implementation team
Adjust or validate the implementation decisions made prior to the POC
There is, however, two downsides to a POC based approach, namely time and money.
Running a POC requires the customer to have manpower, hardware and the time available to implement the solution, validate the solution, iterate changes and re-test and finally analyze the POC findings.
A POC is always the best and recommended approach for any sizing exercise, it will deliver results that are accurate for the unique implementation of the specific customer, and that are as close to deploying the real live solution as possible but without the capital outlay on hardware and project resources.
Hope this helps

Maximum number of Oracle-10/11 instances on a Windows server?

Hi,
What is the maximum number of oracle 10/11 database instances that can be installed on a Windows-32 server.
Also what is advisable?
Assuming each database instance will have no more than 4 concurrent users with light usage.
Windows Server - 2008 4GB Ram Xeon or similar processor.
Many Thanks

You can have any number of instances installed on the server. 42 is a great number.
Just don't turn on more than one or two instances at a time.
Better might be to look at, and understand, 'schema' concept - it may be possible to use multiple schemas in one instance/database to accomplish the same thing as your multiple instance proposal.

Considerations to change LINUX and Oracle users passwords

Dear friends
i want to change password to the following accounts in my oracle servers:
- oracle, OS linux user.
- system, db oracle user
- sys, db oracle user.
but, i want to know what considerations must i have in order to do it that.
VERSIONS:
- Oracle Database 10g Release 10.2.0.1.0 - Production
- Red Hat Enterprise Linux AS release 4 (Nahant Update 4) 2.6.9 5.ELsmp (32-bit)
thanks a lot.

Madrid, and everybody.
does anyone knows ...
- What is the number ID (note) in metalink where are the default account passwords when installed Oracle default database ??? (some days ago i saw but i don't remember the note)
- Are there any link when describe any consideration about OS LINUX users like "root" and "oracle" ?
i must to view that document in order to present my boss.
Thanks a lot !!!!

Find the number of concurrent users in system at a given time

Hi All,
We have the ECC system in which we need to set up monitoring alert which should tell the following things.
1.The number of concurrent users looged currently in the system.
2. List of transaction per hour or user activites with the counts
I want to know whether we have any standard report , function module or tcode through which we can achive this.
A quick response will be appreciated.
Thanks in advance.

How to implement Oracle user/role security with Access front end?

Hi,
We have successfully migrated our Access database tables to Oracle 10g using SQL developer. We've recreated all the users and roles(i.e., access groups) in Oracle and granted rights to tables.
In the Access front end database, in the Database window we have saved linked Oracle tables which replaced the Access tables. The forms, reports, queries run fine with the linked Oracle tables. All the linked table use one ODBC DSN to the Oracle database with the same Oracle user id.
We need to be able to authenticate users into the Oracle database and RE-link the tables based on their own unique user id. By during so we can allow users to use the Oracle standard user id/role and system privileges to control select, update, ect. rights to the database.
I've been able to use the VB code within Access to logon into the database with a unique id, but I have not been able to find out how to RE-link the tables to the unique user id using VB. There should be some way to relink tables dynamically, based on users login into the Access front end.
I don't know a great deal about Access projects, but I do know with SQL server allows login into your Access project and link tables dynamically.
Can someone give me some assistance or point me in the right direction?
Thanks in advance,
Larry

We had one of our programmers here come up with a VB code solution for re-linking table within Access. However the relinking takes 3-4 minutes for 100+ tables.
In an effort to help you understand the situation better, I will attempt to elaborate on the problem:
We have an Access 2003 application which currently has a front end using Access(forms, reports, queries, & VB code) and a MS Access 2003 backend.
We have migrated the backend tables to Oracle. However, we still have a need to maintain the front end in Access, since we have over 60 forms, 40 reports, 200+ queries in Access. Its easy to understand, we have a significant investment in the front end(Obviously, the plan is to migrate the front end also at some future date).
In order to utilized the existing front end, we have to validate and modify the current front end connections to the new Oracle backend. One of the features of Access is that you can "link" tables and save the link for runtime. Each Access table can have its own link which is a separate ODBC/JET connection. As such, each separate link has its own userid/database information.
The other issue with using the Access front-end is that Access utilizes a workgroup file to implement user and group security. The workgroup file contains all the users and which groups the users belong to in Access. Then within Access, you allow users access to object(tables, queries, ect) by their userid and or group. When users open an Access database with Access security enabled, they are required to log into Access. The login is authenticated by the workgroup file. Once, logged into Access, users have rights to Access objects based on their rights granted to their userid and groups they belong. The problem here is that when you remove the linked Access tables and replace them with linked Oracle tables, Access has knowledge about Oracle table rights granted to users; nor would you expect it to.
The dilema is the disconnect between Access and the fact Oracle utilizes a similar but much more sophisticated security model. It creates users and roles(which are similar to Access groups), and again this is independent of Access security.
Our solution was to still use the Access workgroup file security along with the Oracle security model. By using the Access userid and then creating a similar Oracle userid with similar table rights granted in Access, you could apply security within Access and also with the Oracle database.
For example, a user BOB logs into Access via the workgroup file, using VB code, Access then establishes a Oracle connection logining into Oracle using the same unique userid BOB into Oracle.
After connecting and validating user BOB into Oracle, then the Access tables are relinked to Oracle using the user BOB userid and table rights.
This Oracle userid has been granted table rights specific for this userid.This allows the user BOB to use the Access application and still be authenticated into the Oracle database.
The problem with this solution is that the relinking of the saved Access tables takes 3-7 minutes for about 100+ tables. This is not acceptable for users each time they log into the application.
Our current alternative is to use one Oracle userid to login each user, and use Access form restrictions/security to allow/prevent users from updating/viewing data. Obviously, this is not the optimal solution in respect to security, but it at least allows us to control access to the data(via the forms) by using one logon required for each user, and quick startup time for the application.
I understand SQL server does a better job in integration, but we use Oracle which is what I am trying to work with.

Welcome to the new Oracle User Group Community

Welcome to the new Oracle User Group Community. Whether you landed here via the redirect from the previous community site - IOUC.org - or navigated here directly, welcome. This new platform brings new community features to enhance the way you connect with user group peers and with Oracle, as well as make it easier for you to find information through a more intuitive interface. We invite you to provide your feedback on the new site. Log in using your OTN Forum credentials and join the discussion here. If you do not yet have OTN Forum log in credentials, navigate to http://community.oracle.com/community, click on the "Register" link in the upper right corner of the page and create your account.
We look forward to hearing from you.

Hi Kashif,
Glad you like the new Community. Communication among user group leaders works a little differently on this site than on the previous site. Rather than having communication focus around e-mail distribution lists, communication now is focused within the site itself. The intent is that this will provide users the one place to come for information, rather than having to sort through lots of e-mail threads. That doesn't mean that e-mail is completely out of the picture though. Users can opt-in to receive e-mail notifications when an individual piece of content is changed, or when content is posted to a space. Look for the "Receive email notifications" link under "Actions" to start receiving notices. To stop receiving notices, go back to the same content/space and click "Stop email notifications".
Your Relationship Manager will be talking with you and the other leaders in your region over the next few days and weeks regarding how you and your group of leaders want to communicate.
Best regards,
Oracle User Group Team
