Calling Substitution Strings in Supporting Object Installs

So, for lack of a better way of putting it, I have a need to have user input durring the script install part of the supporting objects. I would like to use the Substitution String prompts but can not figure out where it stores the values durring install. It looks as if the system does not commit it to tbl until after the install scripts are done.
I need to create some views that have a different Databaselink based on site location and want the supporting object install scripts to prompt for the name so I can use it in the install process.
Testing on APEX 4.0.1 Oracle 11g
Thanks for any help.

K, found something out. It does store it in a page variable P2103_SS_VALUES and can be called out using v('P2103_SS_VALUES') in the install scripts.

Get Application Id during supporting objects installation

Is there any possibility to get the APP_ID (Application ID) during the installation of the supporting objects?
Iam writing some version information in a application table which says which version is installed and the application id would also ne nice to save.

Installation of Supporting objects fails

I have upgraded successfully to APEX 3.1. I can successfully import packaged applications.
Now when I try to import this particular application from packaged applications named discussion_forum_installer_0.92.sql, it successfully
imports the first step, that is importing the definations.
but when I move on to the next step, i.e install the supporting objects, I get the following error message
The following prerequisite checks failed. Installation of this application's supporting objects cannot continue until these
issues are resolved.
To continue installation after addressing the errors, navigate to the Supporting Object Definitions of this application and
click INSTALL in the Supporting Objects Installation section.
Alternatively, you can deinstall the application definition and reinstall after resolving these issues.
Available Space in KB: 2,624
I even tried to install the supporting objects seperately, still the same problem exists.
Please help!!

I resolved this issue by setting the shared_pool_size to 100M. Previously it was 84M (default, I guess). This was mentioned as one of the pre-steps before installing APEX. But the install went well, just this packaged application was giving errors. Once I increased the size of shared_pool_size, life was good.
Just answering if someone else ran into such issues

Supporting objects was not installed successfully from the APEX 3.2 to 4.1

Hi, gurus:
greetings! I have a question regarding migrating application from 3.2 to 4.1. I need to migrate an application in a APEX 3.2 workspace to a new workspace of APEX 4.1. I exported the application from the APEX 3.2 workspace and imported it again to workspace of APEX 4.1, everything works fine except supporting objects was not installed successfully, and the application cannot show images. Could anyone give me a hint to find the cause and solution?
Thanks a lot!
Sam

Hi, Tony:
Nice to see you again! :) It proved out that was due to the wrong file format, I should choose UNIX file format to export my application from APEX 3.2 workspace instead of choosing DOS file format to export. Though I am still confused, Why this does matter? I used to export and import with random file type, as long as I keep consistency of file type for export and import, it never give me trouble like this.
I got the following error message

How to edit the installation scripts in the supporting objects

I wanted to update one of the installation scripts in the supporting objects. I clicked into that script and use the "script editor" tab. After editing the script, I clicked "Apply Changes" button. It redirected me to the upper level of the page. When I reopen the script, the content of this script is messed up and has the content of another script, not what I have changed. What could happen with it? There is one case that the script was all wiped out!
One general question, how can I easily update the install scripts and reload it without export and import the whole application? or Can I?
Thanks
Fengting

Fengting,
I am not sure what causes this, but I have had the same issue with shared components >> report queries. Sometimes if you have multiple report queries it becomes impossible to edit any of them. If I remember correctly I tried using a different browser and everything seemed to work ok. I was using Firefox when I was having the issue.
Sorry this is not an answer, but I feel your pain!
Cheers,

Inconsistent substitution string expansion in email templates - SCSM 2012 R2

Coming to the conclusion that email templates should not be stored in a custom MP ?
I'm seeing odd begaviour where only some fields are expanded when the email is created. See below example where ID in the subject line has not been expanded but it has been expanded in the body of the email. If I store the custom template in "Service
Manager Incident Management Configuration Library" then it works as expected.
In the following notification, Subject has not been expanded yet when ID is used in a subsequent field in the email body it is expanded (Fault No.)
Also Affected User Firstname has not been expanded.
Subject: Your call has been closed. ID: $Context/Property[Type='WorkItem!System.WorkItem']/Id$
Fault No: IR223
Fault Description: Testing Open, resolve & close notifications
Dear $Context/Path[Relationship='WorkItem!System.WorkItemAffectedUser' SeedRole='Source' TypeConstraint='System!System.Domain.User']/Property[Type='System!System.Domain.User']/FirstName$,
Please be advised that this call has now been marked as closed.
Ian Moran

it should be noted that those substitution strings are contingent on the MP that stores the notification template. for example, 'System!System.Domain.User' is only valid if the
MP Reference "System" points to an MP that contains the element System.WorkItemAffectedUser, and that element is a relationship class definition.
to break it down:
$Context/Path[Relationship='WorkItem!System.WorkItemAffectedUser' SeedRole='Source' TypeConstraint='System!System.Domain.User']/Property[Type='System!System.Domain.User']/FirstName$
$ starts and ends a variable.
Context is one of the keywords that control the behavior of the variable, but in this case, you can read it as the target of the notification template.
Path[] means we are going down the projections path \
Relationship modifies path by specifying which relationship to follow in the brackets with the Relationship element.
SeedRole modifies path by setting which side of the relationship the starting objects is on, in this case, the "context" is the source of the relationship.
TypeConstraint filters path based on what's on the other side of the relationship, in this case, it must be a user.
Property[] means we're reading data from a property of this user, as opposed to pathing again
Type modifies property by controling which class to get the property set from
the last entry is the property name to get data from, i.e. the
FirstName property.
Consider http://technet.microsoft.com/en-us/library/ff719642.aspx and
http://msdn.microsoft.com/en-us/library/ee533748.aspx, thou Context is new for service manager and is largely undocumented, I suspect it was added to address related classes, as (also speculation)
Target may refer only to the target entity without its relationships.

From which version JVM starts supporting Object bindings in collections.

from which version JVM starts supporting Object bindings in collections.
private ArrayList<String> arr = new ArrayList();
this will bind String objects to arr, nothing else will be stored.
which version of JVM should I confirm, before using this feature!!!
please comment.

thanks MLRon!!!
They are called "generics", not "bindings". In any case, you need Java 1.5 (also known as Java 5.0).Can generics be used anywhere, or only with collections.
for eg:-
public class Abc {
public Abc(Object obj) {
if(obj instanceOf String)
doSomething;
if(Obj instanceOf Xyz)
doSomething;
while creating Abc instance can I use this:-
Abc<String> abc = new Abc("abc");
and could we also do this:-
Abc<String[]> abc = new Abc(new String[5]);
and what exception does generics generate, if we don't obey them.
for eg:-
Abc<String> abc = null;
abc=new Abc(new Xyz);
and should generics code be kept in try catch block!!!
please guide me!!!

Thread safety bug in XPS Serializer or FixedDocument sequence? "calling thread cannot access this object..."

Every once in a while (500 iterations or more) I'm getting an exception in the static method below stating "calling thread cannot access this object because a different thread owns it". Thing is, this method references no external objects
and performs no special threading operations. All of the WPF objects are created and consumed in this method. The only aspect that is multi-threaded is that this method can get called concurrently on different threads in the same app domain (the
project is a Windows service). That said the fileToDecollate parameter will be unique every time, so there is no "collision" as far as that goes.
Any ideas?   This is maddening and in theory it should not be possible to blow this error.

I have opened a support case with Microsoft through my employer. I'm convinced there is some .NET framework code that is not thread safe. I did put together a test harness app that demonstrates the problem (within 30 seconds or so after
you start it) and I sent that to MS support. They're looking into it. Anyone else who is curious can download the sample project here:

Calling stopApp(String, Map) on J2EEServer instance results in exception

Hi All,
I'm trying to stop a deployed application on SJSAS 8.1 using AMX beans. The specific problem that I am having is that I receive an IllegalArgumentException when I call stopApp(String, Map) on an instance of J2EEServer.
The API documentation for J2EEServer leaves quite a lot to the imagination and as a result I'm not sure if I'm putting the correct information in the Map object. I have tried all sorts of things including passing in null and empty maps but every combination results in the same exception.
The code I am using is as follows:
        final String host = "localhost";
        final int port = 4867;
        final String user = "admin";
        final String password = "adminpassword";
        final TLSParams tlsParams = null;
        final AppserverConnectionSource conn =
        new AppserverConnectionSource(AppserverConnectionSource.PROTOCOL_RMI,
                                      host, port, user, password, tlsParams, null);
        JMXConnector jmxConn;
        DomainRoot dr = null;
        J2EEDomain j2eeDomain;
        J2EEServer j2eeServer = null;
        try
            jmxConn = conn.getJMXConnector(false);
            dr = conn.getDomainRoot();
            j2eeDomain = dr.getJ2EEDomain();
            final Map servers = j2eeDomain.getServerMap();
            j2eeServer = (J2EEServer) servers.get("sjsas-instance");
        catch (IOException ioe)
            fail("Test threw an unexpected exception, details: " + ioe.getMessage());
        System.out.println("Domain name is: " + dr.getAppserverDomainName());
        Map map = new HashMap();
        map.put(DeploymentMgr.DEPLOY_OPTION_NAME_KEY, "my-application-name");
        j2eeServer.stopApp("spr-adapter", map);The exception that I'm getting is as follows:

Generically calling a method on an object

Hello,
I am trying to write a small utility method to generically call a method on an object.
This is what I have.
    public static void doCall(Object o, String methodName, Object ... args){
        Class[] types = new Class[args.length];
        int i = 0;
        for(Object arg : args){
            types[i] = arg.getClass();
        try {
            Method m = o.getClass().getMethod(methodName, types);
            m.invoke(o, args);
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("Error dynamically calling method " + methodName + " on " + o.toString());
    }It doesn't work because it can't find the method. If I hard code the parameter types as "new Object[] {Double.TYPE}" it works fine (on methods that take a double).
So, my question is, how can I generically set up the parameter types based on the types of the arguments?
Thanks,
~Eric

The problem is not on calling agr.getClass(), your primitive double is already autoboxed to a Double object. It is the doCall(...) method who expects an object, not a primitive. So when giving it a primitive value, java autoboxes it to the corresponding object type.
This means your attempt will only work if the methods to call do not have any primitives as parameters.
Test this code:
public class GenericMethodCaller {
     public static void doCall(Object o, String methodName, Object ... args){
        Class[] types = new Class[args.length];
        int i = 0;
        for(Object arg : args){
            types[i++] = arg.getClass();
        try {
            Method m = o.getClass().getMethod(methodName, types);
            m.invoke(o, args);
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("Error dynamically calling method " + methodName + " on " + o.toString());
     public static void main(String[] args) {
          Callable callee = new Callable();
          callee.callabelMethod(10d);
          GenericMethodCaller.doCall( callee, "callabelMethod", 10d ); // 10d gets autoboxed to a Double object.
class Callable {
     public void callabelMethod(Double o) {
          System.out.println("callabelMethod(Double o) called");
     public void callabelMethod(double o) {
          System.out.println("callabelMethod(double o) called");
}The output will be:
callabelMethod(double o) called
callabelMethod(Double o) called

Finalize() method being called multiple times for same object?

I got a dilly of a pickle here.
Looks like according to the Tomcat output log file that the finalize method of class User is being called MANY more times than is being constructed.
Here is the User class:
package com.db.multi;
import java.io.*;
import com.db.ui.*;
import java.util.*;
* @author DBriscoe
public class User implements Serializable {
    private String userName = null;
    private int score = 0;
    private SocketImage img = null;
    private boolean gflag = false;
    private Calendar timeStamp = Calendar.getInstance();
    private static int counter = 0;
    /** Creates a new instance of User */
    public User() { counter++;
    public User(String userName) {
        this.userName = userName;
        counter++;
    public void setGflag(boolean gflag) {
        this.gflag = gflag;
    public boolean getGflag() {
        return gflag;
    public void setScore(int score) {
        this.score = score;
    public int getScore() {
        return score;
    public void setUserName(String userName) {
        this.userName = userName;
    public String getUserName() {
        return userName;
    public void setImage(SocketImage img) {
        this.img = img;
    public SocketImage getImage() {
        return img;
    public void setTimeStamp(Calendar c) {
        this.timeStamp = c;
    public Calendar getTimeStamp() {
        return this.timeStamp;
    public boolean equals(Object obj) {
        try {
            if (obj instanceof User) {
                User comp = (User)obj;
                return comp.getUserName().equals(userName);
            } else {
                return false;
        } catch (NullPointerException npe) {
            return false;
    public void finalize() {
        if (userName != null && !userName.startsWith("OUTOFDATE"))
            System.out.println("User " + userName + " destroyed. " + counter);
    }As you can see...
Every time a User object is created, a static counter variable is incremented and then when an object is destroyed it appends the current value of that static member to the Tomcat log file (via System.out.println being executed on server side).
Below is the log file from an example run in my webapp.

It really does seem to me like finalize is being called multiple times for the same object.
That number should incremement for every instantiated User, and finalize can only be called once for each User object.
I thought this was impossible?
Any help is appreciated!

Thanks...
I am already thinking of ideas to limit the number of threads.
Unfortunately there are two threads of execution in the servlet handler, one handles requests and the other parses the collection of User objects to check for out of date timestamps, and then eliminates them if they are out of date.
The collection parsing thread is currently a javax.swing.Timer thread (Bad design I know...) so I believe that I can routinely check for timestamps in another way and fix that problem.
Just found out too that Tomcat was throwing me a ConcurrentModificationException as well, which may help explain the slew of mysterious behavior from my servlet!
The Timer thread has to go. I got to think of a better way to routinely weed out User objects from the collection.
Or perhaps, maybe I can attempt to make it thread safe???
Eg. make my User collection volatile?
Any opinions on the best approach are well appreciated.

Xdb_installation_trigger does not support object creation of type SNAPSHOT

hi everyone, i'm using Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit on solaris sparc 5.10
we like to send an email through SSL, and after searching here and there I found out that oracle DB 11g able to go throught the SSL.
since upgrade our DB to 11g would not be an option, so i tried to export XDB of 11g and import it into XDB 10gR2 schema, it was a mess...
then i just reinstall XDB using catnoqm.sql & catqm.sql
and now one of our programmer cant run some script like above

Your video card appears to be missing one or more features required to run Call of Duty.
You should install the latest drivers for your video card, being sure to uninstall the old drivers first. If you already have the latest drivers, you should completely uninstall the drivers and then reinstall them. This fixes most problems. If the game still doesn't work, it may be that your video card does not have the minimum features required. Please check the readme for more information, including a list of supported video cards.
But i got direct rending and i tried to install the mesa-git and libgl-dri-git packages from AUR, but that didn't help.
Can somebody push me in the right direction?

When he installed the new fibre hub, did he use his laptop to take settings off old white hub and put it on new one?... way to check is dial into the hub ( 192.168.1.254 ) go to setting and then wireless, and see if the hub name and key are the same that is printed on card and back of hub....as this could be your problem...one thing to try is set the new hub back to default ( you will have to reconnect anything that uses wireless ) and see if this sorts it out.

Footer navigation using pl/sql - substitution strings

Hi
I want to make a footer navigation (a BLAF like footer with the same captions and links that appear in the Tabs and the Navigation Bar) using a PL/SQL region. The code I want to use should work for any HTML DB application.
The procedure could be defined like this:
PROCEDURE prb_footer_navigation( p_application_id VARCHAR2
, p_page_id VARCHAR2
, p_session_id VARCHAR2);
p_application_id will be used to get the caption and links of the specific application and p_page_id will be used to know which tab is selected.
I'm using this query in the procedure:
SELECT t.tab_text caption
, t.tab_target link
, t.tab_sequence num
FROM flows_010600.wwv_flow_toplevel_tabs t
WHERE t.flow_id = p_application_id
ORDER BY t.tab_sequence
(the user has been granted select from flows_010600.wwv_flow_toplevel_tabs)
The problem is:
tab_target has substitution strings like '&XXX.' or '&PX_XXX.', so how can I get the real link with resolved substitution strings using pl/sql?
Something like function_resolve_string(p_string, p_session_id) would be appreciated...
Thanks in advance!

A.U.,
Have you considered looking at how the navigation bar gets onto your page by examining the page template? You'll find something like this in the body section:
<table width="100%" cellpadding="0" cellspacing="0" border="0" summary="">
    <tr>
      <td valign="top" class="t1Logo">#LOGO#</td>
      <td align="right" valign="top">#NAVIGATION_BAR#</td>
    </tr>
</table>Just copy and paste that onto the end of the body section, or into the footer section of the template, although the footer might not support all the same substitution patterns.
If that's the kind of result you have in mind, do the same thing for the (html) tables that contain #PARENT_TAB_CELLS# and #TAB_CELLS#. I don't guarantee this will work, but it's worth experimenting with.

The extraction program does not support object 0MAT_PLANT

Pessoal alguém já passou por este problema?
Estou tentando fazer um delta no objeto 0MAT_PLANT, mas me retorna sempre este erro.
Já fiz um novo Init, mas o erro continua.
The extraction program does not support object 0MAT_PLANT
Message no. R3009
Diagnosis
The application program for the extraction of data was called up using the invalid InfoSource/invalid InfoObject 0MAT_PLANT.
System Response
The data extraction is terminated.
Procedure
Check the SAP Support Portal for the appropriate Notes and create a customer message if necessary.

Hi Eduard ,
You can try the following steps to solve that
1. Delete the previous Delta Init for the InfoObject
If you have access to R/3 Side you can follow the steps or you can follow the BW Steps
Goto RSA7 ->Select and Delete the Init Request for the InfoObject
From BW Side
InfoPackage-> Inti for Source System -> Select & Delete
the Init Request
2. Execute the Init InfoPackage for the InfoPackage again.
3. After successful completion, execute the delta InfoPackage.
Hope it solves your problem, if not pls let me know.
Thanks & Regards,
