Failover callback not called when listener dies

I need to create a RAC-aware Pro*C application.
I got the preconfigured VirtualBox images with OL 5 and RAC nodes.
The listener is installed on both machines too. They share a single IP address for the listener, which I added to the hosts file:
192.168.56.201 rac-scan.localdomain rac-scanActually, the cluster decides to create a virtual network adapter on one of the nodes and this address is assigned to it and then the listener becomes awailable. When this node dies, the cluster starts the listener on another node.
I don't know, whether it's a proper way. I heard that the listener should be on a separate machine.
But the problem is: when I turn off the node my client program is connected to, the failover callback function is not called. The next oracle operation fails with "ORA-03114: not connected to ORACLE".
I followed http://docs.oracle.com/cd/A91202_01/901_doc/appdev.901/a89857/oci09adv.htm#428924 and https://support.oracle.com/CSP/main/article?cmd=show&type=NOT&id=415245.1 to create the sample program that registers the callback.
Could it be that the failover only works when the DB service fails, but not the listener?

The problem was bad connection string

OCCI AQ Subscription: callback not called

When data changed in table, I want my application to know immediately. So I use the Subsription class. The implements as follows. When I insert row to table set_tab_info, the triggers acts, but the callback not called. What's wrong?

I don't know how to set the callback context. so just use this statement:

Thanks, once again. Sorry for my naive questions, but I'm unable to find a good example for this...
After registering the Subscriber, and creating the environment in EVENT mode, it seems like it is picking up the message. Once I send a AQ message, I get an error from visual studio, telling me the variable ESP was not properly saved across a function call. At least it reacts now :)
Could it be that I'm doing something wrong when defining or hooking my callback function? The breakpoint in the callback function is never called....
my registering routine now looks like this:
void aq_connection::create_callback() {
payload = new Bytes(env); //is this the correct way?
Subscription sub(env);
sub.setSubscriptionNamespace(oracle::occi::aq::Subscription::NS_AQ);

sub.setPayload(*payload);
sub.setCallbackContext((void *)this);
sub.setSubscriptionName(quename + ":" + config->subscribername);
sub.setPresentation(oracle::occi::aq::Subscription::PRES_DEFAULT);
sub.setNotifyCallback(&aq_connection::event_message);
subs.push_back(sub);

I thought it was ok to create a local Subscription instance, as I put it into the global subs-vector.

Region Monitoring iOS 7 : didEnterRegion method is not calling when app is killed by user or by OS in iOS 7 only. It is working fine when it is in background. and the same code is working fine with iOS 6 for both app in suspended mode and background mode. What changes I have to made to work great in iOS 7 also.

I rewrote code for debugging purpose and tried to catch error using GetLastError();  method,
but it only printed 0. Below is code snippet; I think Create() throw an exception
and code goes to catch block.
LONG ConnectTS(CString strIP, UINT n_Port)
try{
          ErrorLog(0,0,"ConnectTS is calling Create [is going to call]","");
          if(!Create())
// Exception Line
n_Err = GetLastError();
return NET_INIT;
catch(...)
                   DWORD errorCode = GetLastError();

Occi AQ callback not called

I have written code for dequeing messages with blocking calls (Consumer::recieve), which works fine. Now I try to register a callback function, which should be called when a message is in the queue.
Some code:
void aq_connection::create_callback() {
payload = new Bytes(env); //?
Subscription newSubscription(env);
newSubscription.setSubscriptionNamespace(oracle::occi::aq::Subscription::NS_AQ);
newSubscription.setProtocol(oracle::occi::aq::Subscription::PROTO_CBK);
newSubscription.setPayload(*payload);
newSubscription.setCallbackContext((void *)this);
newSubscription.setSubscriptionName(quename + ":" + config->subscribername);
newSubscription.setPresentation(oracle::occi::aq::Subscription::PRES_DEFAULT);
newSubscription.setNotifyCallback(&aq_connection::event_message);
mye callback method is defined like this:
static unsigned int event_message(oracle::occi::aq::Subscription &sub ,oracle::occi::aq::NotifyResult *not) {
std::cout << "got message\n";
return 0;
The problem is, the event_message function is never called... I send in messages into the queue with this stored procedure:
message := OURMSG_TYP(p_id, p_msg_type_id, p_msg, p_operation, p_data);
enqueue_options.visibility := DBMS_AQ.ON_COMMIT;
     enqueue_options.relative_msgid := NULL;
     enqueue_options.sequence_deviation := NULL;
     enqueue_options.transformation := NULL;
     message_properties.priority := 1;
     message_properties.delay :=     DBMS_AQ.NO_DELAY;
     message_properties.expiration := p_expiration;
     message_properties.correlation := NULL;
     --message_properties.recipient_list :=
     message_properties.exception_queue := vcp_exception_queue_name;
     --message_properties.sender_id :=
     message_properties.original_msgid := NULL;
     message_properties.transaction_group := NULL;
     message_properties.user_property :=     NULL;
     DBMS_AQ.ENQUEUE(
     queue_name => our_queue_name,
enqueue_options => enqueue_options,
message_properties => message_properties,
payload => message,
msgid => message_handle
Any obvious reason why my callback is never called?

Sverre

Failover did not happen when network switch went down!!! PLEASE HELP

Hi gurus,
Yesterday one disaster struck my RAC database. We have two node cluster and it is 10.2.0.2, both of them located in different sites, yesterday suddenly power went down and the one of the network switch went down and got destructed, node one of RAC database was connected to that switch, but the failover did not happen to the node two as this should be the case when one node goes down the other should be available for all the node one sessions/connections.
when I tried to ping/telnet the node 1, it was not happening because the switch was down, the network guyz connected the cables to other switch available. When I connected to the node 1, it was showing "Oracle is not available" message.
And when I tried the other node, it was the same case but I did not see any error in alert log file. Then my TL restarted both the nodes and then the database was available.
I am very confused that how the failover did not happen and how the database went down, PLEASE suggest something to how to identifiy what was happened. Thanks & Regards
Edited by: user1221 on Mar 18, 2009 1:09 AM

About Oracle RAC ... you have 2 nodes ... You have to connect 4 IPs.
I mean
- IP public node1
- IP public node2
- IP Virtual node1
- IP Virtual node2
When node1 down
You can not ping "IP public node1", but you should ping "- IP Virtual node1", because it should up on node2.
But not bind 1521 port.
Idea about failover
you have to create new difference Service...on RAC Database!
and on your client have to set TNS to on failover and balance (if you used OCI), you can use TAF feature
Example:
DB =
(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = db01-vip)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = db02-vip)(PORT = 1521)) (FAILOVER=ON)(LOAD_BALANCE = yes) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = NEW_SERVICE_DB) (FAILOVER_MODE = (TYPE = SELECT) (METHOD = BASIC) (RETRIES = 180) (DELAY = 5))))
If you use JDBC, can not use TAF.
Anyway, I suggest you read more about RAC on http://otn.oracle.com/rac and http://oracleracsig.org
Good Luck

Failover did not happen when one node went down!!! PLEASE HELP

Hi gurus,

Thanks for your reply,
after the network switch was replaced we connected to both the nodes and found that the instances are down with no reason given in the Alertlog file. We just restarted both the instances and then the database was up and the clients connected to both the instances with equal sessions on both the instances. I want to know that whether the failover can be done at the application side or it should be done on the database side i,e; in tnsnames.ora file with the required parameters? as in our scenario there is no failover configuration in the tnsnames.ora file.
Thanks & Regards

Command button action not calling when in subview

i have a page that is fine when it's in it's own view...
the command button calls a managed bean's method..
<af:commandButton text="Call Method"
action="#{backing_myPage.CallMethod}"
binding="#{backing_myPage.commandButton1}"
id="commandButton1"/>
but when i remove the view tags and include it in a main index.jspx page
that has a main view and a tabbed panel with showdetailitems and
for each showdetaileditem i have a subview
and then an include
<f:subview id="discovered_subview" rendered="true"
binding="#{backing_index.mypage_subview}">
<jsp:include page="/mypage.jspx" />
</f:subview>
Mypage renders but the commandbutton's action is not called..
but is called when run as a standalone page
tia

I also have the same problem as above. Changing the dropDown values to String does not fix it.
I am using Netbeans Visual Web Pack.
I drag a drop down box onto a brand new page.
I double click the drop down box and in the processValueChange action i put System.out.println("Hello World");
In the init() method i add 2 options to the drop down box:
"option 1", "1"
"option 2", "2"
values are Strings
I press F6 to run
I notice that the drop down box is correctly populated.
I change the drop down box selection
Nothing is printed.

NW2004s SP12, action not called when Save button pressed

Hi Experts,
I have a strange behaviour in my Interactive form SAVE functionality. If its a large form, the SAVE button does not call corresponding action method in the implementation.
However it does when the form size is small eg 1.5Mb or so.
Please advise. This is quite urgent.
Thanks in advance
Mona

Hi!
If you commit the form and insert data after that,
that data will not being commited to the database and got lost until you use
something like forms_ddl ( 'commit' ); after the insert.
:system.last_query, which is the very last query of a block in your form,
will never show an insert in any trigger.
May a commit-trigger is not a good place for an insert.
But anyway, hope this help you.

Substitution not called when posting from a different system through ALE

Hi
When I post an FI document using FB01 in FI system,the posting calls a substitution to fill the cost center if the cost centre is empty.We have a custom function module which substitute the cost center
The HR system is linked to FI system through an interface.
So when HR system post a document through FI,it post successfully if the cost center is filled.
But it fails to call the substitution when posting a document without cost center.
There is a statement in our custom fm
ASSIGN ('(SAPF110S)XBSEG[]') TO <lfs_bseg_tab>.
ASSIGN ('(SAPMF05A)XBSEG[]') TO <lfs_bseg_tab>.
These statements fails to work when calling remotely from HR system and so it doesnt fill <lfs_bseg_tab>.
So the HR guys telling tat because of this reason,the substitution is not called.
Could anyone please help?

Initializer block not called when static method called

public class Initializer {
     Initializer(){
          System.out.println("Constructor called");
               System.out.println("CLASS INITIALIZED");
     static void method(){
          System.out.println("Static method called");
     public static void main(String[] args) {
          Initializer.method();
From the JLS
A class or interface type T will be initialized immediately before the first occurrence of any one of the following:
T is a class and an instance of T is created.
T is a class and a static method declared by T is invoked.
[b]
But when i call the static method , if the class is initialized shouldnt the initializer block be called, it is not called, why.

Perhaps running something like this will add a little more colour?:
public class Initializer {
    static {
        System.out.println("First static initializer");
        System.out.println("First instance initializer");
    Initializer() {
        System.out.println("Constructor");
    static {
        System.out.println("Second static initializer");
        System.out.println("Second instance initializer");
    static void staticMethod() {
        System.out.println("staticMethod");
    void instanceMethod() {
        System.out.println("instanceMethod");
    public static void main(String[] args) {
        System.out.println("main");
        staticMethod();
        new Initializer().instanceMethod();
}

Position not saved when battery dies

I got an old 2nd gen nano, that is permanently connected in my car.
I use it to listen to audiobook.
Problem is:
an hour after turning off the engine, ipod nano loses power (battery not holding charge), and next time I power the engine, nano comes back up, but has no recollection as to what was playing, or even if I choose manually the track - position is lost
any way to 'bookmark' or 'save' last position?

Youve got to be kidding me.
Are you being serious?
The problem is not that the battery sometimes runs out.
The problem is that the SIM is not recognized when it does.
Its not "bad" or "wrong" or "improper" for your phone to die.
Why am i having this absurd conversation?

Callback Methods called when a UI Componet is displayed

Hi ,
There are 3 callback methods called as preInitialize , initialize and creationComplete that will come into picture when a UI Component is initialized .
Can anybody clarify my confusion here , what does a UI Component Mean here ??
Is it a Container like a Application or a control like Button ??
Please share your ideas . Thanks for reading .

Air.swf GetApplicationVersion callback not called

I am trying to use air.swf from
http://airdownload.adobe.com/air/browserapi
per the Adobe documentation to detect if an air application is
already installed. I'm using getApplicationVersion but the callback
function is never called. launchApplication() and
installApplication() work fine.
The code looks like this:
_air.getApplicationVersion(appID, pubID,
versionDetectCallback);
VersionDetectCallback() is never called. I de-compiled the
air.swf and ran the code directly to try and figure out what's
failing. But I get the same result. I can see the timer on the
LocalConnection endpoint timing out after 5 seconds. I just can't
figure out why the appinstaller is not calling back. The actual
call (taken from the decompiled swf) looks like this:
airappinstaller = new ProductManager("airappinstaller");
var launchArgs:Array;
launchArgs = ["-isinstalled", appID, pubID, "adobe.com" + ":"
+ lcName, "onApplicationVersion"];
airappinstaller.launch(launchArgs.join(" "));
where onApplicationVersion is the endpoint callback function
and lcName is the LocalConnection name.
Anyone know why GetApplicationVersion() doesn't work?
