Limiting Resources for a database

Hello,
We have a several Oracle 9i databases in production. Some of them generate more revenue than others, and therefore are more important than the databases that do not generate much revenue.
Is it possible to limit the resourse usage for the less important databases? For example, is it possible to set the databases that do not generate much revenue to use less CPU on the server? If yes, could you kindly point me in the right direction?
Kind Regards,
Rudi

First queston, are all the databases on same server or on different servers? Is on the same servers, then, try to minimize the SGA of those databases and also create a profile to handle all the resource like cpu time and other stuff.

Resource for Forms/Database Security

My company is taking the Oracle plunge in the next 2 weeks and I really need to find some good books, or resources to get off on the right foot.
The first thing I would like to deal with is security. I need to figure out how to allow some users to update a field while denying other users. I need to know what kind of information I will need to know.
Right now the scope of the project is to create an applictaion in Forms and Reports to run the business. Then we will also be working with HTMLDB, Designer, Portals, and other Oracle tools. So the problem is that I can create a table in the database to hold security settings, but I want the settings for Roles and Access rights to persist through all objects.
Can ALL of the security be done on the database itself???? or will we need to do coding on the Forms and Reports also??
Basically I need someone to point me to the right resource to start implementing security on the database and Forms, since that is the first step (in my opinion) in developing a good application.

All security can be done in the database. However, you probably want to have the security rules in your Forms as well. If your Forms are totally open for any action (insert, update, delete), the user will only get an error message when hitting the Save button. Only then are the database securities checked.
Usually the Form also checks if a user is allowed, e.g., to update a record. If not, in the Form you will set the record to non-updateable. That way the user immediately gets an error message, even before trying to save the changes.
Another approach is to have only ONE database user with all privileges for the application. Application users and authorization rules are stored in application tables. When you start the application, you automatically log in with a database username and password that are hidden or encoded in some way. Then the user logs in with the username and password that are stored in the application. This approach is very common in web environments.
I need to figure out how to allow some users to update a field while denying other usersI would never go as far as applying security on field level. That may become an administrative nightmare.

Resource estimation/Sizing (i.e CPU and Memory) for Oracle database servers

Hi,
I have came across one of the requirement of Oracle database server sizing in terms of CPU and Memory requirement. Has anybody metalink notes or white paper to have basic estimation or calculation for resources (i.e CPU and RAM) on based of database size, number of concurrent connections/sessions and/or number of transactions.
I have searched lot on metalink but failed to have such, will be great help if anybody has idea on this. I'm damn sure it has to be, because to start with implementation of IT infrastructure one has to do estimation of resources aligned with IT budget.
Thanks in advance.
Mehul.

You could start the other way around, if you already have a server is it sufficient for the database you want to run on it? Is there sufficient memory? Is it solely a database server (not shared)? How fast are the disks - SAN/RAID/local disk? Does it have the networking capacity (100mbps, gigabit)? How many CPUs, will there be intensive SQL? How does Oracle licensing fit into it? What type of application that will run on the database - OLTP or OLAP?
If you don't know if there is sufficient memory/CPU then profile the application based on what everyone expects, again, start with OLTP or OLAP and work your way down to the types of queries/jobs that will be run, number of concurrent users and what performance you expect/require. For an OLAP application you may want the fastest disks possible, multiple CPUs and a large SGA and PGA (2-4GB PGA?), pay a little extra for parallel server and partitioning in license fees.
This is just the start of an investigation, then you can work out what fits into your budget.

If the database was not registered in the OCR, after restoring the database you must manually add the database in the OCR (add database and instances)

Cannot enable IORM on OEM , kept getting:Resource cannot allocated for a database

Oracle Exadata X4, trying to allocate IORM through OEM 12c.
After chose the database, disk io allocation % and io allocation limit %, when I click update, it kept giving me this error: Resource cannot allocated for a database
I want to know if IORM is already setup or not, if not , how do I get it set?
Thanks in advance.

Hi user569151 -
I have configured IORM from the command line, cellcli, a number of times but haven't used OEM to set it up. IORM plans are setup on the Exadata storage cells and unlike its counterpart, DBRM, it manages workloads across databases not internal to a single database.
To see the current IORM plan and see if it is active and has an objective - which are required for IORM to start managing IO resources and before any inter-database or category plans can be created - you can use the following cellcli command:
cellcli -e list iormplan detail
This can be executed from the linux command line on each of the storage cells... or even better, if you have dcli setup you can execute it for all your storage cells at once from the linux command line of one of your compute servers, e.g.:
dcli -g cell_group cellcli -e list iormplan detail
You can then determine if you need to activate it, set an objective and then can look into creating your inter-database and/or category IORM plans. Look at the following MOS notes for some information on creating IORM plans:
Configuring Exadata I/O Resource Manager for Common Scenarios [ID 1363188.1]
Configuring Resource Manager for Mixed Workloads in a Database [ID 1358709.1]
Hope that helps get you started. Good luck!

Limiting / ChargeBack for Virtual Networks Per Tenant

Hi,
Is it possible to limit the number of virtual networks that a tenant can provision in Azure Pack, or even better is it possible to ChargeBack at a fixed cost per virtual network that is provisioned?
Reason being that every virtual network that is created uses one public IP address and these are limited and cost money to purchase... they are not an infinite resource for us.
Thanks in advance.
Microsoft Partner

If you follow Mark's advice, you will at the Plan level in the service admin portal see that you can limit the amount of VM networks that can be created.
This is for the plan in general.
Regarding usage and billing. Are you using CloudCruiser or any other third party integration with Azure Pack today? If you don't plan to expose any of the cost metrics to your tenants, I would say it is a matter of decision on how you plan to bill the tenants
in the end of the day.
Also note that you can "easily" create your own billing adapter using the billing API's available (using Powershell or/and JSON).
We have done this for several customers and stored the required data in a dedicated database for reporting.

Right way to configure Tomcat JDBC resource for MaxDB

Hi,
i need to configure one tomcat server with a pool of connections for a MaxDB instance with follow database parameters:
MAXUSERTASKS=150
SESSION_TIMEOUT=60
i do this configuration on tomcat:
<Resource name="jdbc/myApp"
                auth="Container"
                type="javax.sql.DataSource"
                username="DBUSER"
                password="secret"
                driverClassName="com.sap.dbtech.jdbc.DriverSapDB"
                url="jdbc:sapdb://dbserver/DBNAME"
                maxActive="150"
                maxIdle="75"
                validationQuery="SELECT NOW() FROM DBA.DUAL"/>
is this the right way? there is a way to check if the pool is working at database side? at java side i checked that the javax.sql.DataSource.loginTimeout is Unavailable, then what is the better way to avoid errors like:
2008-06-02 13:54:36 2165 WNG 11824 COMMUNIC Releasing T187 command timeout
i think that this problem occurs because the SESSION_TIMEOUT is 60, and the loginTimeout is Unavailable at javax.sql.DataSource then the DBCP of tomcat dont know when need to revalidate the session.
thanks for any help.
Clóvis

Hi Clovis,
to be honest, I'm no Tomcat expert at all. All I can do is read the documentation.
The error message you posted was about an timeout due to a too long idle session.
From the changes in your connection pool setup I cannot see any parameter that would influence this.
Instead - as already written - you may either want to change the session timeout in general, for the user or (by adding some connection parameters) for the sessions.
Concerning the question on wether it's better to have many connections or just a few - well this depends on what the java tasks do with the sessions.
The connection pool is used for saving resources on the database side and the time necessary to logon and create a session.
So whenever any of the java tasks needs a db connections it should "just get one" from the pool.
When you have "high load" (by the way what exactly does that mean? High CPU usage on the J2EE server? Huge transaction volume? Many parallel transactions?) this does not change.
Anyhow you have to be aware of the fact that the database can only process as many SQL requests in parallel as there are user kernel threads (UKTs) and each of the UKTs need to be able to run on a seperate CPU core. Therefore if it's necessary to have real parallel SQL activity many connections may not be the best idea.
On the other hand this requirement is seldom necessary - most often sessions can wait a bit until they get the reply from the database and synchronize on each other later on. At least that's how we do it with NetWeaver.

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)?
The following is my configuration in the conf\mapViewerConfig.xml:
<map_data_source name="mvdemo12"
jdbc_host="127.0.0.1"
jdbc_sid="orcl12c1"
jdbc_port="1522"
jdbc_user="mvdemo"
jdbc_password="7OVl2rJ+hOYxG5T3vKJQb+hW4NPgy9EN"
jdbc_mode="thin"
number_of_mappers="3"
allow_jdbc_theme_based_foi="true"
editable="true"/>

But it does not work.
After use "sqlplus mvdemo/[email protected]:1522/pdborcl", it connected to the Oracle database 12c.
Does anyone know it?
Thanks,

For 11.1.1.7.1 use the syntax for jdbc_sid, i.e.
//mypdb1.foo.com as described in the README,
- MapViewer native (non-container) data sources can now use database service name in place of SID. To supply a db service name, you will use the same jdbc_sid attribute, but specify the service name with double slashes in front, such as follows:
<map_data_source name="myds"
    jdbc_host="foo.com"
    jdbc_sid="//mypdb1.foo.com"
    jdbc_port="1522"
/>
For 11.1.1.7.0 use a container_ds instead.
i.e. instead of using
<map_data_source name="my_12c_test"
                   jdbc_host="mydbinstance"
                   jdbc_sid="pdborcl12c"
                   jdbc_port="1522"
                   jdbc_user="mytestuser"
                   jdbc_password="m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q="
                   jdbc_mode="thin"
                   number_of_mappers="6"
                   allow_jdbc_theme_based_foi="false"
                   editable="false"
   />
use
<map_data_source name="my_12c_test"
                   container_ds="jdbc/db12c"
                   number_of_mappers="6"
                   allow_jdbc_theme_based_foi="false"
                   editable="false"
   />
In my case the Glassfish 3.1.2.2 JDBC connection pool definition was
Property
url jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name
Uncheck the Wrap JDBC Objects option in Advanced panel, i.e. the Edit JDBC Connection Pool Advanced properties page.
Add a JDBC resource for that newly created pool
Use that in mapviewerconfig.xml as above

Best Practice for Distributing Databases to Customers

I did a little searching and was surprised to not find a best practice document for how to distribute Microsoft SQL Databases. With other database formats, it's common to distribute them as scripts. It seems that feature is rather limited with the built-in
tools Microsoft provides. There appear to be limits to the length of the script. We're looking to distribute a database several GBs in size. We could detach the database or provide a backup, but that has its own disadvantages by limiting what versions
of the SQL Server will accept the database.
What do you recommend and can you point me to some documentation that handles this practice?
Thank you.

Its much easier to distribute schema/data from an older version to a newer one than the other way around. Nearly all SQL Server deployment features supports database version upgrade, and these include the "Copy Database" wizard, BACKUP/RESTORE,
detach/attach, script generation, Microsoft Sync framework, and a few others.
EVEN if you just want to distribute schemas, you may want to distribute the entire database, and then truncate the tables to purge data.
Backing up and restoring your database is by far the most RELIABLE method of distributing it, but it may not be pratical in some cases because you'll need to generate a new backup every time a schema change occurs, but not if you already have an automated
backup/maintenance routine in your environment.
As an alternative, you can Copy Database functionality in SSMS, although it may present itself unstable in some situations, specially if you are distributing across multiple subnets and/or domains. It will also require you to purge data if/when applicable.
Another option is to detach your database, copy its files, and then attach them in both the source and destination instances. It will generate downtime for your detached databases, so there are better methods for distribution available.
And then there is the previously mentioned method of generating scripts for schema, and then using an INSERT statement or the import data wizard available in SSMS (which is very practical and implements a SSIS package internally that can be saved for repeated
executions). Works fine, not as practical as the other options, but is the best way for distributing databases when their version is being downgraded.
With all this said, there is no "best practice" for this. There are multiple features, each offering their own advantages and downfalls which allow them to align to different business requirements.

About listeners for different databases in the same ORACLE_HOME

Hello experts, I have a doubt
I have installed 3 different databases in the same server which OS is Suse Enterprise 10. At this moment I have just one listener that registers all the services. The number of connections are big for two of the three databases so I do not know what might be the best practices for this environment. I have some question I would like you suggestion for me:
DB version: 11.1.0.7
Should I have three listener, one for each database?
Is a good practice to have only one listener for multiple instances in the same server?
Are there differents between have only one listener for all the instance and have one listener for instance?
What about the performance?
Than you in advance, I hope you can guide me.

Best practice is not to have multiple databases on one server, depending on resources.
Should I have three listener, one for each database?
No. That is pretty undesirable and requires more administration.
Is a good practice to have only one listener for multiple instances in the same server?
Yes. Remember the listener is only a broker and there are no permanent connections between client, listener and database.
Are there differents between have only one listener for all the instance and have one listener for instance?
Yes. The latter is an administration nightmare.
What about the performance?
Who cares? The only factors are
listener.log becomes too big --> set up proper cleanup procedures
The number of semaphores is exceeded (Unix) or no more threads can be created (Microsoft winblows), which will give rise to ora-12500.

11gR1 backup for 11gR2 database clone.

Hi all,
Our OS is 64 bit RHEL 5.7. On this we have EBS R12.1.3. with db version 11.1. Recently I installed EBS 12.1.3 (actually installed 12.1.1 and upgraded to 12.1.3) on a VM and upgraded its 11.1.0.7 db to 11.2.0.3. Now as I want to test the CPU patches on this instance I decided to clone the production instance here. Since this is a higher version oracle home (11.2.0), I will have to do some new steps here but am not sure what they are. I have restored the controlfile, restored and recovered the database and opened the database with STARTUP UPGRADE command. What steps should I perform next?
Regards,
Vinod
