Listener registration

Hello,
I'm using Sun's Application Server. Go Sun!
I declared a ServletContextListener in the deployment descriptor. When I GET requested the servlet, the server responded w/ a 404. Did I miss something?

...by the way, the servlet is found when no listeners are declared.

Static listener registration 11gr2 RAC Primary and standalone Standby

Hi Guys,
I have to build up a single instance Physical Standby(Dataguard) for a primary RAC (11.2.0.1).The concern or rather confusion we have three SCAN LISTENERS across 2 node cluster,in order for me to have static registration for duplication of database for standby i need to have it put in the listener.ora .
Do i have to create the static listeners for default listener as well as the scan listeners?

My understanding is No.
The Oracle instance would automatically register the local listener to SCAN listeners, so I believe just the default needs this.
This document has Scan listener example and none of them use a _DGMGRL

JMX MBeanServerDelegate listener registration

I'm trying to register a listener with the MBeanServerDelegate in SAP
Netweaver. I'm always getting back a NPE when I call addNotificationListener
on the connection:
java.lang.NullPointerException

r(MBeanServerConnectionImpl.java:730)
        at
com.intersperse.agent.sapconnector.TestMBeanServerDelegate.main(TestMBeanSer
verDelegate.java:50)
It seems to apply to any MBean that I try as well, not just
MBeanServerDelegate. I have a very simple test:
Properties env = new Properties();
env.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"com.sap.engine.services.jndi.InitialContextFactoryImpl");
env.setProperty(Context.SECURITY_PRINCIPAL, "Administrator");
env.setProperty(Context.SECURITY_CREDENTIALS, "control");
env.setProperty(Context.PROVIDER_URL, "10.70.20.136:50004");
MBeanServerConnection serverConnection =
JmxConnectionFactory.getMBeanServerConnection(JmxConnectionFactory.PROTOCOL_
ENGINE_P4, env);
serverConnection.addNotificationListener(new
ObjectName("JMImplementation:type=MBeanServerDelegate"),
        new NotificationListener() {
                public void handleNotification(Notification notification,
Object handback) {
                        System.out.println("handle note: " + notification);
        }, null, null);
Anyone know what could be causing this?

Database listener registration

All,
How do you get a database to register itself with the listener?
rgds
Alan

Hi,
Oracle 10gR2 - Technically, a DB registers itself automatically with the Listener, at DB creation time.
But, I have found that I need to update my listener.ora and tnsnames.ora file manually, and restart the listener.
Hope that works.

Listener Removal Strategy

May be dumb - but I create a lot of objects in an application
written in 3.0. When they are done doing what they do, I would love
to be able to call a utility routine that shimply looped through
the listeners that are registered for all objects and remove them
where is .target is the object I am done with. I don't know if this
is possible but it would significantly simplify my code and I
suspect the internals of listener registration, removal and cycling
does the .target check anyways......
Am I barking up the wrong tree, is this something someone had
done or is the mere thought of it stupid from the start......
bob

Kglad - no, just the listeners. I would like something like
for each(listener in the listener stack) {
if listener.subscribed_to_target = mytarget
remove listener
In my coding - any listeners set up in an object are dealt
with by that object when done - typical remove_listeners funtion
removing listeners set-up, typically on instantiation of the
object. Listners that subscribe to the object events from other
objects deal with removal separately.
It would clean things up tremendously to simply walk the
listener stack and where the target is the object that is no longer
needed, I could have some iteration to remove all listeners that
have that object as a target.....
Hope this makes sense....
ccoonen - I fear the use of "weak reference" but do so as is
suggested in some texts. If I could confirm that the listener was
removed and collected as of a certain point I would follow your
strategy, but I always hesitate to rely on something I can not
test.

How do you add an ActionLister to a JTabbedPane???

I have an application that utilises a JTabbedPane. All of the tabbed panes that I add to it are declared in separate classes. Added to the main Frame is also a JMenu and a JToolbar. I can detect which pane is enabled when a button is selected using for example,
if(jtpFantasyLeague.getSelectedComponent() == FLI).
What I would like to do however, is enable and disable the relevant menu and toolbar items as each tabbed pane is selected.
The problem is I don't know how to implement it. I started trying ActionListeners with no success, but a book a have talks vaguely about ModelListener and an EventListener???
Any help, or a link to a relevant tutorial would be great.
Also I would like to know, can I monitor which Pane is selected from the main class where the JTAbbedPane is instantiated or do I need to do it separately in each class that I have added as a tabbed pane??
Thanks in advance for any help,
Kris

Have your main class implement ComponentListener to check on show/hide events. If your main class needs to know about these events, there are a few ways I know of to do so:
a) Inside your main class: FLI.addComponentListener(this);
b) If the panes themselves need to control listener registration, register the main class with a callback. I assume you have a class extending JPanel that represents the contents of each pane. Declare a constructor that requires a reference to an object of type MainClass (or whatever it is). In the constructor, set an attribute (declared as final MainClass owner; in the attribute section) to that arguments value. Whenever the pane needs to add a listener registered to the main class, have it call addComponentListener(owner).
c) This is somewhat sketchy, but...I'll write it anyway. Declare a static variable (active, for example) in MainClass of type MainClass. In your MainClass constructor, code MainClass.active = this;. In your pane's code, instead of addComponentListener(owner), code addComponentListener(MainClass.active).
That oughta do it.
Good Luck, and happy coding!

Why I can,t login???

Hi guys.I'am starting with Oracle db 10g.I just had installed db on windows xp, and it works vell.
When I tried connect to SQL Plus form start menu, I just can't do it, this is what I get "listener doesn't currently know of servise requested in connect descriptor "????
When I login from CMD, I can log as "sqlplus /nolog" , and "sqlplus hr/pass", but I can't login as SYSDBA, SYS.
What to do?
Thx

Hi,
In 10g you have to edit listener.ora file and add sid parameter.
One reason is default listener registration is DYNAMIC you have to change DYNAMIC to STATIC.
edit your listener.ora file like below
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oracle\product\10.1.0\Db_1)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = orcl)
(ORACLE_HOME = C:\oracle\product\10.1.0\Db_1) )
C:\>LSNRCTL stop
C:\>REM WAIT FEW SECONDS

Active-Passive Failover cluster in Windows Server 2008 R2

Hi,
As per the client requirements, I build an active-passive Oracle 11g R2 database cluster in Windows Server 2008 R2.
(Used Microsoft cluster as Client don't have Fail Safe licence)
As per the configuration, I follow the below mentioned steps:
a)OS vendor configured Active-Passive Windows Cluster
b)Installed Oracle 11g R2 on both the nodes with same ORACLE_HOME name
c)Create Listener and configured it with cluster IP in Node1
d)Create Database from Node1. Physical files location are all in Storage
e)Create Oracle Service with the same name in the 2nd node and copy all the files like spfile,tnsnames.ora,listener.ora,password file to Node2
f)Configure Listener with the same Oracle SID.
g)Test database failover from Node2 with Listener registration
h)Open the Windows Failover Manager to configure the Oracle Database and Listener Service in the Cluster Group
Now I am facing problem by moving Cluster Group movement. Whenever trying to moving the group, Listerner service is not getting up by Cluster Manager as quorum is not included in the group and that quorum disk is not moving in the failover node with the Oracle Cluster Group. As per my understanding Quorum having information of Cluster IP which has been configured with Listener.
But when I am shutdown one node, then in the other node all the resources successfully moving and cluster able to online all the resources. I guess at that time Quorum is also moving and thus cluster can able to make Listener online.
Please suggest how to resolve this issue. Means how can I make Listener up instead having any dependencies with Quorum in the fail over node?
Thanks a lot for your help.

hello
I was going through your post and i am also doing the same thing here at our organisation for Oracle 10g R2
Can you pls send me any docs u r having for configuration of Oracle in windows clusters .
And, can you pls elaborate on this point
e)Create Oracle Service with the same name in the 2nd node and copy all the files like spfile,tnsnames.ora,listener.ora,password file to Node2.
Pls send me the details at [email protected] or you can contact me at 08054641476.
Thanks in advance.

Ora-12523 error-not able to connect wid database

hi ,
my name is varun
i am using oracle 9i on window xp
my clint and server r on same machine
i was working on the database with a non-sys user
suddenly i got one errror
tns packet faliue
then after that
ORA-12523: TNS:listener could not find instance appropriate for the client
connection
could u plz help me out and resolve this problem
thanx in advance

Varun,
There is no problem with listener registration, problem is with the database processes (allowed connections). If the max number of processes allowed is reached, pmon doesnt allow any new connection from listerner. that the root cause for this problem.
Fix:
Increase the number of process in init<SID>.ora to higher value and restart database.
1. edit the file D:\oracle\ora92\database\initdb01.ora
Processes=200 ----- any higher value required
2. login as sysdba Shutdown the database -----
3. startup database -----
SQL> startup pfile=D:\oracle\ora92\database\initdb01.ora

CS3 / Javascript - Script Error 27: Stack overrun

Hi
I have a script who is running all the time (like an Idle). This script calls a method in my own plugin, this method execute an action in my plugin. During this action, I call another Javascript to checkout a document from a content management system.
This means:
- A running script (Idle) calls a method in my plugin written in C++
- The plugin calls another Javascript to checkout the document while the first plugin (Idle) is still runnung.
This generates an error 27, stack overrun. I have tried several possibilities (with and without a main function, with and without #targetengine and so on), but always the same error.
- What can I do?
- Is it possible to run another script during the execution of one?
- How can I do that?
- Can I run two Javascript in her own environments? I mean own stack, own main and so on...
Thanks for any hint.
Hans

John is right, this is more of a plugin/SDK question, I would have expected it in that forum first hand.
Hans has cross posted this question into a swiss/german scripting forum with more details, and I've given a few suggestions. It broils down to the fact that the plugin access to scripting in CS3 had to address the JavaScript scripting subsystem rather than talk to a specific engine. And my strong guess is that the RunFile function triggered by the idle task of the first plugin is not reentrant so the second plugin can not invoke a method the same way.
My suggestions, in brief: upgrade to CS4 where engines are independently addressible. Alternatively, one can try the other methods to invoke the script - RunScript rather than RunFile, or even use the callback mechanism that underlies the event listener registration. Easily accessible from the same interface class.
Of course for the reentrancy problem I would not expect a Stack overrun error, so maybe it is not reentrancy at all but just the obvious - the second plugin calling itself in recursion. A breakpoint should easily tell.

Implementing active data service proxy for MySQL database

Hi,
I am referring "Oracle Fusion Developer Guide - Building rich Internet Application..." to implement Active data Service to update Af:Table for any change in the MySQL database.
The book discusses of a class which extends ADS "BaseActiveDataModel" which should handle starting and stopping of active listener and listener registration.
1. Does this class is sufficient to detect changes coming from MySQL database or is it specific to Oracle database?
2. Also the book does not discuss about the code for starting stopping or registering active listeners. Can someone guide me to some reference material or to a right place which explains me what kind of code does these methods require?
3. Also I wonder if anyone knows, if we can differentiate between events generated from different database tables. (I guess we need to do that by using 'instanceof' operator and comparing ViewObjects from my project).
(Just trying to develop my understanding around various ADF concepts.)
Thanks!!
(Have also referred http://technology.amis.nl/2012/06/18/notifying-adf-applications-of-database-changes-fast-and-lean-using-database-query-result-change-notification-part-one/
not sure if that's the way I need to register the listener. ADF should have made that easy.)

Detecting Client Disconnect

I am looking for a way to determine when a client connects and disconnects (especially the latter) from the grid. Two approaches come to mind:
1) Polling for something that appears/disappears when a client connects or disconnects. The most obvious candidate is a lock. This approach is inefficient because it requires polling. It also raises the issue of how clients are distinguished, although that is not difficult (e.g. - invocable increments a counter which is used as a basis for the key to lock).
2) Getting a notification when this happens - preferably in-grid. However, I could find no listener for either the client connect/disconnect event or for locking. Likewise, using custom cache implementations (overriding a class and calling it out in the cache config) doesn't seem to provide notification of either locking, or (an alternate approach) the registration of a listener.
Overriding a cache indeed provides notice of listener registration, but it appear to be a general listener which is feeding some other internal Coherence facility which manages the specific per-client listeners.

Answering my own question, after research and help from Gene Glyzer:
There are a couple of ways to do this:
1) A client can lock a phantom (or real) entry in a cache. When the client member of the cluster goes away, the lock will be released.
2) Tracking cluster members:
* Add a listener:*service = CacheFactory.getService("name").addMemberListener(...)*
* Get the membership information (synchronously guard against listener events):*Set members = service.getServiceMembers()*
* Use subsequent listener events to adjust the members set.

Pfile

Hi all, I am using Oracle 10gR2 on Solaris 10.
We have a RAC, two nodes as well as ASM on them. Both the nodes are using their local PFILES. Currently the sga_target is set to 0 on my DB. I have checked the init.ora files on both the nodes and there is no entry on sga_target.
#### SGA Tuning ####
*.sga_max_size=12G
*.shared_pool_size=1024M
*.db_cache_size=4096M
*.large_pool_size=1024M
The total size of the SGA is 12G, but if we add up the below values they dont sum up to 12G. Is this normal? If I want oracle to use automatic memory management do I need to manually add the parameter in the PFILE? Do I need to make some other changes as well?
