i am having a problem in connecting the tables to each other. i know that it is all about the primary and foreign keys. how can i connect them and i want to fuly understand its importance. i need this because i will be doing a tree in my project. i cannot have the 2 attributes that i needed coz i d not have them in my tree binding editor
thanks for your helpMaileen,
for database design questions, please refer to the database website here on OTN. A primary key is a unique key in one table referenced by a column (the foreign key) in another table. In JDeveloper you can use the database modeller to visually design tables that use primary/foreign key relationships

Coherence Support -
I am an instructor at a two year technical college. We are starting a class the administration want to call Oracle. It is basically SQL and SQL Plus. I took a class recently in this subject and feel fairly confident in handling that. BUT - - Where do you go to find out some basic information about ORACLE itself. Everything I see or sites I go to are so complicated. Lots of information but nothing basic - - like from the beginning. If a student asks, "What is Oracle?" From everything I see it is huge and very difficult to explain.
I need some basic help in this area. Does anyone know where there is a good tutortial about the basics of "What is Oracle?" Not SQL information but Oracle itself.
Thanks - - if you can help me!Well dear i am learn oracle in 1998 after that due to some problems i left computers. but now a days i am again start to do OCP (DBA) and after that OCP Professional. I need your help too. Now come to your point whhat is oracle. Oracle is relational data base system. and now what is relational data base system. well i dont have words to ex[lain you but if u learn about relational data base then u must understand. and for oracle we use sql language. we write some statements behind the form or icons(button) like
search a person on age limit is graeter than 18
and we write
select all whose age > 18
i think so about this query bz i forgot every thing.
i need ur help to start oracle again. thanks

Tutorial for Oracle Coherence Release 3.6 does not work
I am new to Oracle Coherence and just download the newest release 3.6 of coherence together with JDveloper (Studio Edition Version 11.1.1.3.0, Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660) and started to go throught the tutorial step by step. Having completed chapter 1 and 2 and started to work on chapter 3: Accessing the Data Grid from Java and get stuck with the sampleas code related to classes "MyFirstSample" and "MyFirstSampleReader". According to the doc once the cahce-server is running (by running cache-server.cmd in dos) then
run a) MyFirstSample which will put an "Name" entry to myCache and exit
b) run MyFirstSampleReader which will retrieve the entry "Name" populated with "MyFirstSample". But i got null value back.
The following are logs for cache-server (I), MyFirstSample (II) and MyFirstSampleReader (III) respectively:

Oracle Coherence*Web and BlazeDS: Multiple FlexSessions created for the same HttpSession
Hi all,
I have searched this forum and found a lot of good information from Alex Glosband and others about the infamous "Detected duplicate HTTP - based FlexSessions, generally due to the remote host disabling session cookies. Session coolkies must be enable to manage the client connection correctly." message.
It seems, however, none of the cases are identical to ours. This is ours:
- Resin 3.1.9
- Oracle Coherence 3.7.1 with Coherence*Web (session replication)
With this setup we get the "Detected duplicate HTTP..." message on the first attempt to use BlazeDS and on every subsequent call. The same client and server code works fine in a local sessions setup. With Coherence 3.3 (currently our production environment) it seems to occur less frequently, but still as frequent as it is a major issue for us. It fails even with a single node using in-process distributed caching in our test setup (as well as with multi node out of process caching in our staging environment, for Coherence knowledgeable the resin app server runs with tangosol.coherence.session.localstorage=true in the first case and false in the second).
Both the listener and message broker are mapped as "Coherence aware" in web.xml[1] so that they should use clustered sessions.
We have been digging a bit and we found out that if we commented out lines 427 and 434 of flex.messaging.endpoints.BaseHTTPEndpoint from version 4.0.0.14931 it seems to mask the bug. We added some logging in the setupFlexClient method and it seems that we get more or less a new FlexSession for each and every call - but they have the same cookie and thus underlying HttpSession. I.e. the list returned from flexClient.getFlexSessions() keeps growing. Thus we are not so keen on going to production with that memory leak and the above mentioned ugly hack of commenting out the detection of duplicates.
We use request scope for the remote object, but could in theory use any scope as we do not really have any state on the object itself, it is all HttpSession state and return values that are key (logon is performed prior to doing the first blaze call, in pure forms and ajax, and it is not a timing issue in that regard we are seeing).
Hope someone can shed some light on what can be happening. Is there any "reference testing"[2] or something when the FlexSessions are created that makes them being created as new? Where are they created? We do not know the inner workings of the BlazeDS source, we just watched the call trace of the unwanted invalidation and found that to be line 427 of flex.messaging.endpoints.BaseHTTPEndpoint.
Can we disable FlexSessions? Since the flex and plain html parts of the app share the sessions, we always use FlexContext.getHttpRequest().getSession() anyway, never storing any state directly in the FlexSession or on the remote object. Or maybe there is a config option to help us with this detection (or creation) of multiple FlexSessions?
Cheers and TIA,

[2] - As you undertstand this is speculation based on pure air, but it could be that in Coherence there was a serialization/deserialization happening somehow that would break such a test?Just a quick update, it seems things are running in a stable fashion (and without visible memory leaks, just keeping the latest FlexSession) with these changes in BaseHTTPEndpoint:
* Overrides to guard against duplicate HTTP-based sessions for the same FlexClient which will occur if the remote host has disabled session
* cookies.
* @see AbstractEndpoint#setupFlexClient(String)
@Override
public FlexClient setupFlexClient(String id) {
log.debug("setupFlexClient start id " + id);
FlexClient flexClient = super.setupFlexClient(id);
// Scan for duplicate HTTP-sessions and if found, invalidate them and throw a MessageException.
// A request attribute is used to deal with batched AMF messages that arrive in a single request by trigger multiple passes through this
// method.
boolean duplicateSessionDetected = (FlexContext.getHttpRequest().getAttribute(REQUEST_ATTR_DUPLICATE_SESSION_FLAG) != null);
if (!duplicateSessionDetected) {
List<FlexSession> sessions = flexClient.getFlexSessions();
log.debug("Client has " + sessions.size() + " sessions.");
int n = sessions.size();
if (n > 1) {
int count = 0;
for (int i = 0; i < n; i++) {
if (sessions.get(i) instanceof HttpFlexSession)
count++;
if (count > 1) {
FlexContext.getHttpRequest().setAttribute(REQUEST_ATTR_DUPLICATE_SESSION_FLAG, Boolean.TRUE);
duplicateSessionDetected = true;
break;
// If more than one was found, remote host isn't using session cookies. Kill all duplicate sessions and return an error.
// Simplest to just re-scan the list given that it will be very short, but use an iterator for concurrent modification.
int i = 0;
if (duplicateSessionDetected) {
List<FlexSession> sessions = flexClient.getFlexSessions();
log.debug("Detected sessions from client: " + sessions);
for (FlexSession session : sessions) {
if (session instanceof HttpFlexSession && i < sessions.size()) {
// log.debug("----> sessionId: " + session.getId());
// Enumeration e1 = session.getAttributeNames();
// while (e1.hasMoreElements()) {
// Object key = e1.nextElement();
// log.debug("--------->" + key + "--------->" + session.getAttribute((String) key));
// session.invalidate();
flexClient.sessionDestroyed(session);
i++;
// Return an error to the client.
// DuplicateSessionException e = new DuplicateSessionException();
// e.setMessage(ERR_MSG_DUPLICATE_SESSIONS_DETECTED);
// throw e;
return flexClient;
It is not exactly beautiful (to say the least), but if it does the trick I might just be pragmatic enough to go with it... NB: I am of course not proposing this as a patch to this file or anything, it is just an ugly hack for our specific case, but maybe the information can help the BlazeDS team find the root cause making it incompatible with Coherence*Web.
Will give it a test run on our staging servers. -

Edited by: Anand Gupta on Dec 4, 2009 5:10 PMDavid,
Thanks for your detailed response. I will try all that you suggested and let you know my observation at the end. To give a back ground of the application I am working on.
Background
Try to replace home grown cache (very well optimized uses custom serialization using NIO bytebuffer etc.,) my mandate is to replace the legacy cache with coherence (I love coherence product (at least 3.4) from my previous job experience). Since all kind of optimization is done in legacy application I am converting NIO byteBuffer generated by legacy serialization to byteArray and converting ByteArray into POF. Also for various other reasons, I have to send entry processor to do even get and put data from the cluster.
Raw Data Set Size
My data size is just 500MB (In Production). I put enough cache nodes so that raw data is just 50MB per node. (Since it is compute heavy with entry processor and the number of clients are going to be ~2500)
What was happening when I got the exception?
I was doing stress testing of the cache. Not sure if that put lot of garbage in some of the node hence may be the garbage collection pause triggered the re-distribution of partition set. Since the stress testing was on the way it might had cascading effect on all the nodes.
Datagram Test result.
Tx summary 4 peers:
life: 96 MB/sec, 68774 packets/sec
now: 100 MB/sec, 71378 packets/sec, packets/burst: 1029, bursts/second: 69.41594
Success rate ranges from 0.87 to 1.0
Is a success rate less than 0.98 a cause for concern?
Regarding Size (to keep the extend client always connected to the proxy)
I do size request every 5 sec. if there is not other request has gone to the cluster in the past 5 sec.
In one of the oracle presentation it was said that "If you have map listener's and no other request from a long period of time extend client has to do a periodic size request to make sure that connection to proxy is alive"
In this regard my question is "Can the same effect achieved by doing member listener on the extend client and on disconnection do the size request?"
Proxy Size guide lines
In production number of extend clients are going to be ~2500 connected all the time.
Of which 2000 clients with few map listener + entry processor gets (Each of the clients will have distinct and disjoint set of data on which they work and listener)
And the remaining ~500 clients will do all kinds of request on the entire data set.
In this circumstance is there any recommendation for Number of extend-client : Number of extend-server : Number of threads ratio?
Regards

Oracle Coherence Technical Architecture
All,
I am currently looking to re-architect a Java based web service project that handles millions of (read-only) transactions a day. We currently return results very quickly (~3 milliseconds per transaction).
We have 12 application servers running IBM Websphere Application Server that hits a 3 node Oracle RAC. Very few database calls are made, however, since important data is held in an in-memory (heap) cache that is currently about 6 GB. The data isn't static, but it is only updated 4 or 5 times a year.
New enhancements are going to push the cache size to around 25 GB. We could get new RAM, but we have run into garbage collection issues with the current heap size.
I am researching new caching implementations, and Oracle Coherence has come up. I have two questions:
1) Do the coherence servers typically sit on the database tier, or the application tier?
2) Does anyone have any performance metrics on local, in-memory cache lookups versus using a distributed caching approach like Coherence?
Thanks,

2) Does anyone have any performance metrics on local, in-memory cache lookups versus using a distributed caching approach like Coherence?
IMHO, you should measure scenarios relevant to you, not use other people's metrics which likely are not applicable to your environment and requirements anyway. You should write your own tests with data retrieval and data storage implemented for your needs and optimized for Coherence's capabilities.

Oracle Coherence 3.7.1, It's always creating a new cluster in linux m/c.
Hi ,
I am facing an issue with Oracle Coherence 3.7.1 in linux m/c , where it’s always creating a new cluster, even if I start a new member provided with same cluster name as argument. -Dtangosol.coherence.cluster=name
It’s not joining the existing cluster , it’s always creating a new cluster with same name in Linux m/c.
But when I tried the same thing in windows m/c , it working fine , even If I start N number cache server’s it joining the same cluster as one more member.
Please someone help me, why it’s always creating a new cluster in linux m/c with same name ? why new VM’s are not joining the existing cluster? , Is there anything extra setup I need to do for Linux m/c.
Thanks in Advance.

For unicast, you need to define the override file as under:

<port system-property="tangosol.coherence.wka1.port"> coherence-node1-port</port>
</socket-address>
<socket-address id="2">

<port system-property="tangosol.coherence.wka2.port"> coherence-node2-port</port>

</logging-config>
</coherence>Use the property -Dtangosol.coherence.localhost=coherence-node1-ip and -Dtangosol.coherence.localport=coherence-node1-port for coherence server1 and -Dtangosol.coherence.localhost=coherence-node2-ip and -Dtangosol.coherence.localport=coherence-node2-port for Coherence server 2.

What are the prerequisites to install and configure Oracle Coherence 3.4
What are the prerequisites to install and configure an Oracle Coherence (3.4 Grid version) on RHEL5.0 system?
I want to make an Oracle Coherence Gid Data system for testing purpose using 3 machines.
What kind of network configuration is OK?
What software should be installed in advance？
Thank youHi,
I would read through the Testing and Tuning section of the following page.
http://coherence.oracle.com/display/COH34UG/Usage+(Full)
Even though you are not about to go into production I think the Production Checklist has some very useful information.

Is there any product that is same as oracle coherence but is open source?
I donot know if it is suitable to post this question here, but I really want to know it, so please help me~
Is there any product that has same function as oracle coherence but is open source?You may have a look at for instance JBoss Cache. It does however (as far as I know) lack Coherence most useful (and powerful) caching architectures (i.e. "partitioned" and "near" caches). Nor do I belive you should expect the same level of stability or proven track record for use in demanding applications as coherence has.
This said I think it can be a perfectly useful product for some applications were you don't need the most advanced features and don't have the budget for Coherence or some other commercial product - it is after all a lot better than writing your own project specific caching solution...

Please suggest me the best way to start learning about Oracle Purchasing.
Hi,
I have started reading about Oracle Procurement. I have an over all idea of how ERP functions. Anyhow I am like a fresher to ORACLE APPS. Can you pleasesuggest me what is the best way to start learning about Oracle Purchasing.
Is it is throuhg user guides or some thing else..... can you please specify the references also.......
Thank you so much.If you have a sponsorship, I would recommend taking classes with Oracle University. The other resources are documentation, functional and technical depending on what your interests are.
If you can load Vision database or access vision database (I think solutionbeacon offers a free account to login and play around), that will be another resource as well.
As you learn, join as much user groups like this one, and review all questions and answers in the discussions to understand and learn more.
Hope this helps.
