What's resource-ref for?

I'm a JNDI newbie, so I hope this isn't too dumb. :-)
I have a web app that I'm running in Tomcat 4.1.10 against a MySQL database. The app gets the DB using JNDI as described in the JNDI howto that comes with Tomcat. Everything works fine. Question is this: when I remove the <resource-ref> element from web.xml and restart the server, it still runs fine--yet every set of instructions I've seen on using JNDI from Tomcat says that I need to have <resource-ref> in web.xml. What's it for?
Thanks,
Willie

Here's my take:
The JNDI binding are done when the Tomcat parses server.xml.
The resource-ref is used to declare to the container how the application is going to use the named resource. The container will 'default' to a standard use; say 'Container' authentication and 'Shareable' which it will use if there are no overides provided in web.xml.
Each application can overide this 'default' behavior by specifying the appropriate settings for <res-auth> and <res-sharing-scope>.
Just an educated guess.

What programming resources exist for doing direct TCP/IP communication with the FP-1600 ethernet interface?

I am no stranger to IP communications (UDP or TCP), and I am attempting to build a project controlled by a Linux system. The FieldPoint 1600 looks interesting, but I can find no programming manual describing it's use.. only a dumbed-down 'user manual' describing how to use Windoze software. Is there any hard documentation on this device, or should I look elsewhere for my solution?

Nathaniel,
The FP-1600's use a National Instruments proprietary communications protocol. At this point in time, there are no plans to release the protocol. On the other hand, the protocol for the FP-1000/1001 serial network modules is published in the FP-1000/1001 Programmers Reference Manual and can be implemented on any platform.
If you are using LabVIEW, I have recently created a driver for the serial modules, that is multi-platform, that will be included in the next version of FieldPoint Explorer, but I will also be making it available for download independantly of FieldPoint Explorer.

What's the actual function of resource-ref in web.xml

I was configuring JNDI datasource in tomcat and found an confusing fact.
If I have the JNDI resource configuration in the context configuration of the project, I could get access to the JNDI element with or without the resource-ref configuration in my web.xml.
Can someone tell me what exactly resource-ref does in the web application?
Thank you.

Thank you, Sunny.
But I still don't quite understand.
In Tomcat, this <resource-ref> seems to be optional, right?
Plus, there should be a virtual name and actual location in the configuration.
<resource-ref>
<description>Resource reference to a factory for java.sql.Connection.</description>
<res-ref-name>jdbc/mydb</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
So, is "jdbc/mydb" the virtual name or the actual location of the resource?

Security Right 'Resource' id for 'User Impersonation For Seller' right

Hi,
Can someone tell me whats the RESOURCE id for security right 'User Impersonation For Seller'?
I need this to populate the workbook. None of the standard roles have this in E-Sourcing 5.1, so the standard workbook doesnt contain this right.
Manually this right can be set in the security profile in drop down 'Users and sercurity'.
Thanks & Regards,
Srivatsan

Hi
RESOURCE ID for security right "user impersonation" is usermgmt.impersonation

How do I know what is the minimum resource requirement for OLAP 11g?

How do I know for OLAP 11gR1 ...
1. what is the minimum number of CPUs and speed required
2. how much minimum physical memory, SGA, PGA etc. is required?
Regards, Anirban

Hello Anirban,
In summary, since the OLAP option is an option to Oracle Database 11g, Enterprise Edition the minimum requirements in order to run the database would be identical to those necessary to run a "Data Warehousing" type installation. That being said starting up a database is a far cry from actually performing well while accessing and building OLAP Cubes in your Database.
There are lots of things to consider. For example: the complexity of your model; data sparcity; level of aggregation; system load, SLAs, etc..
Lets look at true minimum requirements and then consider what it would take to achieve good performance in your environment
TRUE MINIMUM...
I performed a test in my environment (Oracle Database 11g Release 2 (11.2.0.2.0) on Oracle Enterprise Linux 5.5) using Analytic Workspace Manager 11.2.0.2.0A and found the following minimum settings to work against the OLAPTRAIN schema (You may find it here http://www.oracle.com/technetwork/database/options/olap/index.html). This is a very small schema which we use for demonstration purposes.
I discovered that the database started with a memory_target of only 160m (apparently this is the absolute minimum for my environment). I knew that if the database successfully started that I would be able to query the Cube but maintain it? Running queries against the OLAPTRAIN Sales Cube, despite being slow, worked as anticipated. Next, I performed a maintain operation on the Sales Cube where I had to abort the job because it ran into memory issues at 160m, however, when I increased it to only 180m it did a complete maintain in a reasonable timeframe, albeit slow considering the limited resources.
MINIMUM REQUIREMENTS TO ENSURE REASONABLE PERFORMANCE IN YOUR ENVIRONMENT
Most importantly ensure you have a good cube design
Run a sample set of your data in order to define what "reasonable performance" is for your environment. Create a small representative cube in order to test both build and query performance while collecting and analyzing database statistics through AWR and ADDM. For OLAP option specific queries please take a look at http://wiki.oracle.com/page/OLAP+option+-DBASample+Scripts.
You could creat a view on top of your fact table and use the view to generate your OLAP Cube. This will allow you to test a more manageable amount of data. For example, if you have 10 years of data and want to determine the footprint and resources required in order to manage a Cube of this volume then consider scoping it down to a few months first then increase it by a measured amount in order to predict requirements. Monitor your resources and ensure you balance I/O, memory and processors. Since the OLAP option is a Enterprise Edition option it falls under Data Warehousing. As such there is plenty of literature available on oracle.com in order to define what it takes to achieve a balanced Data Warehouse.
I would recommend contacting Oracle Consulting or an Oracle Partner to determine the best fit for your environment.

What are Resource Bundle Best Practices techniques for Enterprise App?

Regarding JDeveloper: 11.1.1.6.0, Studio Edition
I was wondering if someone could provide advice on Best Practices for managing Resource Bundles for an international Enterprise Application.
I have been reading textbooks and throughout the web, and I can find different options available. And I can find cautionary tales to get it right at the beginning of Development, but I cannot find Best Practices suggestions.
For instance:
- Should I use XLIFF Resource Bundle, Properties Bundle, or List Resource Bundle?
- What are the benefits and disadvantages of storing the Key/Value pairs in the database?
- It seems that storing in the db would make maintenance easier, because applications do not need to be redeployed, but would they be slower?
- One textbook indicates that "One Bundle per Project" is preferred for ViewController Project, and "One Bundle Per File" is preferred for Model Project. However, I cannot help but think if the whole Enterprise used just one Resource Bundle, it would save typing cust_id/Customer Number in 10 different Bundles.
- One text indicates how to maintain translated versions of Access Keys, if the Bundle is a Properties Bundle, but provides no assistance for other Resource Bundles.
Advice regarding Best Practices would be quite helpful.
Sincerely,
Arie

Hi There, What is the Location for resource folder in apps dir.

Hi There,
What is the Location for resource folder in apps dir Structure.

Are you trying to open the form locally or remotely?
If locally then do the following:
- From 'regedit' navigate to HKEY_LOCAL_MACHINE\Software\Oracle
- Search for FORMS60_PATH
- Make sure that "D:\oracle\visappl\au\11.5.0\resource" exist in FORMS60_PATH
If remotely the do the following:
- Copy "D:\oracle\visappl\au\11.5.0\resource" to your local machine (for example D:\resource)
- From 'regedit' navigate to HKEY_LOCAL_MACHINE\Software\Oracle
- Search for FORMS60_PATH
- Make sure that "D:\resource" exist in FORMS60_PATH
Close/Open the from builder, you should be able to open the form then.

Looking up Managed ConnectionFactory by JNDI Resource-Ref

Thank you in advance for your help...
I'm writing an Enterprise Java Bean using WebLogic Workshop that needs
to access a connection factory defined in a deployed Resource Adapter.
I'm trying to access the server managed connection factory through the
use of a resource-reference defined in the EJB file.
The resource ref is defined in the EJB header:
* @ejbgen:resource-ref
* sharing-scope="Shareable"
* auth = Container
* jndi-name = Target_7
* name = db/cf/Target
* type = javax.resource.cci.ConnectionFactory
* @ejbgen:session type="Stateless" default-transaction="NotSupported"
* ejb-name = "UberPhoneBook"
* @ejbgen:jndi-name
* remote = "ejb.UberPhoneBookRemoteHome"
* @ejbgen:file-generation remote-class = "true" remote-class-name =
"UberPhoneBookRemote" remote-home = "true" remote-home-name =
"UberPhoneBookHome" local-class = "false" local-class-name =
"UberPhoneBookLocal" local-home = "false" local-home-name =
"UberPhoneBookLocalHome"
And the lookup is done in the EJB code:
private void initialize() {
if( this.initialized ) return;
try {
// Lookup the ConnectionFactory we should be using
InitialContext initCntx = new InitialContext();
ConnectionFactory cf = (ConnectionFactory) initCntx.lookup(
"db/cf/Target" );
this.conn = (Connection) cf.getConnection();
this.initialized = true;
} catch( Exception e ) {
throw new EJBException(e);
But I'm running into problems. My lookup results in a Name Not Found
Exception, and I can't find my resource reference in the JNDI namespace.
I'm using the bean in a JSP page, and it is declared in the usebean tag.
Any ideas what my problem could be coming from?
Thanks,
Chris M.

          Hi!
          Did you deploy your rar file? Which jndi name has the connector?
          If you use a reference try "java:comp/env/" as prefix. Would be helpful if you
          cut the passage about the reference from your ejb-jar.xml and weblogic-ejb-jar.xml
          file and post it.

Some doubts in using resource-ref,connection pool n Data-source

Hi all ,
I need little bit clarification in the following points.
1) Does the connection pool which is created can be displayed in JNDI Tree???
I am seeing only DataSOurce in the JNDI Tree Only.
2)In case of Bean Managed Persistance, in ejb-jar.xml,
I had given the following info.
<resource-ref>
         <res-ref-name>ramukkDataSource</res-ref-name>
         <res-type>javax.sql.DataSource</res-type>
         <res-auth>Container</res-auth>
     </resource-ref>Does the <res-ref-name> refers to Datasource Name??
In weblogic-ejb-jar.xml
<reference-descriptor>
       <resource-description>
          <res-ref-name>ramukkDataSource</res-ref-name>
          <jndi-name>ramukkpool</jndi-name>
       </resource-description>
     </reference-descriptor>Here <jndi-name> refers to connection pool as per weblogic bible book.
If so when i deployed my ejb into the server iam getting Datasource cant be found.
If i had given like the following,
In ejb-jar.xml
<resource-ref>
          <res-ref-name>jdbc/ramuJndi</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Container</res-auth>
     </resource-ref> In weblogic-ejb-jar.xml
     <reference-descriptor>
          <resource-description>
           <res-ref-name>jdbc/ramuJndi</res-ref-name>
           <jndi-name>jdbc/ramuJndi</jndi-name>
       </resource-description>
    </reference-descriptor>Then only my ejb code is successfully deploying doing some work which is as per xpectation.
Can any body tell why I have to give the same name for <res-ref-name> n <jndi-name>??
I am working on this problem from last one week. Still not found the solution.

If not how to deploy the connection pool into server??)
I did not get any errors in the console.
Now i am creating a datasource

I have read the documentation.
I changed my class to oracle.jdbc.pool.OracleConnectionCacheImpl from
oracle.jdbc.pool.OracleConnectionPoolDataSource
I observed in the EM that the Open JDBC Connections and Total JDBC Connections are the same. When I used oracle.jdbc.pool.OracleConnectionPoolDataSource my Total JDBC Connections was increasing and Open JDBC Connections remains 0.
My question still remains unanswered, could some kindly help.
Q? I have defined a data source in JDeveloper using
oracle.jdbc.pool.OracleConnectionCacheImpl
In my java bean I am using the code pasted below to make a connection to database.
Can some one tell whether I am using the correct method of connection pooling mechanism or do I need to make some changes? This application uses JSP and used by lots of people which hits database very frequently.
Any help is highly appreciable.
Thanks in advance.

How to map a resource-ref in Jdev11 deployment plan editor

Hi all,
I have a ADF/BC web application where the BC4J application module does connect to a JNDI data source.
The ViewController project does declare the Datasource as needed resource in its web.xml:
<resource-ref>
<res-ref-name>jdbc/wlogDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Now i need to map that resouurce-ref to an actual data source that exist in the application container at deploy time.
As already in JDev 10.1.3 the deployment-plan editor provided during deployment from JDeveloper does not provide any means to enter the deployment mapping for that resourc-ref (When clicking on the node (which is named resouce-ref - that becomes very confusing in case you have defined three resource-refs in your web.xml) the right pane shows a gray pane without any edit controls) So I cannot enter the resource-ref-mapping unsing the Jdev UI.
My workaround in 10.1.3 was to save the deployment plan to disk and manually edit it, adding
<resource-ref-mapping name="jdbc/wlogDS" location="jdbc/wlogTestEnvDS">
</resource-ref-mapping>
to the orion-web-app document for that webapp
But in Jdev 11 the deployment plan file format changed (including some binary inline checksums???)and when doing exactly the same thing, the loading of the manually edited file into Jdev Deployment plan editor fails with

So no chance here to add a resource-ref-mapping. The alternative way of specifying a resource-ref-mapping using the web-based deployment proces of the Enterprise manager is impossible because the 11g preview OC4j does not include an enterprise manger web-application.
So how do I deploy the application correctly other that manually modifying the deployed orion-web-app.xml file in j2ee/home/application-deployments/earName/warName/orion-web-app.xml after deploying the app without a resource-ref-mapping? Because doing that step manually each time is quite annoying.
Greetings,
Thomas

Seems i'm slowly answering my own questions :-) I finally got my RMI service, even using several methods. But ...
It doesnt help me as the lookups are not done on the context classloader it seems. That means i need to add all my service jars to the global class path causing massive sealing issues with the war contained jars. Pretty useless. All the needed stubs etc are in the war.
But as it seems that the web app needs to contain deployment site info (sun-web.xml) anyway, i could just as easy read my own web xml from the context and resolve the services myself. But i do wonder how this is supposed to work with EJB and CORBA stuff. The samples actually also needed to add stuff to the global class path.
I'm probably not the easiest customer as i write this kind of middle ware for a living but i really like sjsws. It makes my own one partly obsolete as it is almost as fast and has all the fancy deployment stuff (in my case i use an in-house mobile agent frame work and agents that travel the various networks ) and infinitely easier to learn to work with and understand In case anyone is wondering i wrote Uhura because 1. i needed speed so it is a servlet based webserver and not a web server with a servlet module. 2. could not wait on ibm to fix bugs in webspere and we only used the servlet bit. 2. i needed full J2EE security and 3. i needed it to run on many OS'es
That is why i still need the same war files to be able to be deployed in both systems as i still need my systems going on IBM iservers etc.
Again i would welcome some feed back on such and related issues
Cheers,
Peter

What are the settings for rework order quality inspection

What are the announcements for renting VPS?

What are the announcements for renting VPS? For details, understand VPS and make the choice of rental; for Taiwan VPS and Hong Kong VPS, without records, unlimited contents, wider range, and more efficient experience. Your server will show its excellence with the advantages.
Most station agents become less inclined to virtual hosting, for national space, domain name records are needed, which waste the time; for overseas hosting such as Korea hosting, US hosting, no records, but slower speed than national space; therefore, more and more station agents prefer servers, but because the price of servers are too high, they turn their focus on VPS.
The following are the announcements:
1.Open remote desktop lander:
Start-run-mstsc or start-procedure-nearby-remote desktop connect
2.Several conditions for account halt:
First, client side login cause account halt
Second, certain account quits the remote control in midway when it runs routine
Third, certain routine is restricted by synchronous operation of system administrator.
3. Not install the third party firewall
If you need firewall, please use windows firewall, the third party firewall in VPS will cause system collapse and data loss, the system automatically obtains the newest windows patches and install itself, which do not require human operation. Installing system patches in VPS sometimes will heavily lead to VPS collapse and data loss.
Do not modify remote desktop port.
Because of the specialty of VPS system, default remote desktop port is 3389, do not modify randomly, or the remote connection will be out of work.
4. Except some special conditions that user registration is needed for certain procedure, when the remote connection has been close down, do not forget logout user to save memory resource, and prevent the loading connection next time, if it happens, reboot VPS.
5. VPS has been set with relative security when it was paid, with high security. It suggests that do not open firewall randomly, if you open it by your own, the following ports should be opened: 21(FTP), 3389(remote connection), 80(website http), 3306(MySQL), 1433(SQL Server). Timely check whether there is suspicious account or system log, download 360 safety guard to avoid these files and process.
6. Try not to modify registry hand-actuated, ensure the reboot of VPS. Modify remote ports please add the modified port in firewall first, and then reboot.
7.Modify IIS installation files, backup these files, and then modify them with the software that can keep the file layout, prevent these files from destroying IIS.
8.Website service of VPS and FTP service of IIS are default to open hand-actuated, set Web Publishing Service as automatically if you are station agent. If you often use FTP service of IIS, please set FTP Publishing Service as automatically, i.e. reboot it automatically. If you use serv-u, tick all the system service terms. In the terms of security and resource consumption , it suggests that those users who seldom use FTP do not set it as automatically.

Hi there
"So for ALL the apps, the annual monthly fee is £46.88, but you can rent occasionally for £70.32 pm.... ?" Correct
£17.58 single app plan requires an annual commit - it's £27.34 for the month-to-month plan without annual commit.
Thanks

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....
Regards,
Karthik

Hi, Karthick,
karthiksingh_dba wrote:
... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.

What's resource-ref for?
