References question
I wanted to create references that did some cleaning up by themselves when they were discarded because of low memory, so I tried to extend the clear method, but it seems that it is never called.
I thought, reading API and docs I found, that the GC calls the clear() method of a SoftReference when it moves the reference to the queue. But it appears that the GC does not use this method, but in stead clears the referent in some other way. Can someone confirm this, and maybe explain why?
I suppose I will need to use a referencequeue and poll every now and then ...
I thought, reading API and docs I found, that the GC
calls the clear() method of a SoftReference when it
moves the reference to the queue. But it appears that
the GC does not use this method, but in stead clears
the referent in some other way. Can someone confirm
this, and maybe explain why?That makes sense, although I cannot confirm for sure. My reasoning follows...
It is my understanding that the GC is guaranteed to clear and collect all SoftReference referents before throwing an OutOfMemoryError. If the GC clears the referents by calling an extensible method - in this case, clear() - it can no longer make this guarantee... simply because it cannot guarantee that your custom clear method will not require the allocation of memory that isn't available.
I am not overly knowledgeable about References, but I believe that PhantomReference is the only kind that prevents the object from being collected before the reference is cleared... this should allow you to perform your cleanup. If anyone has an example of this, I would be obliged to see it, because I have been unable to think up an example that would work...
Since you cannot get a reference to your object through a phantom reference, you can tell when an object is eligible for collection, but not which object or what resources it holds that might need to be released. It may be possible to create the reference as an inner class of the object requiring cleanup, but this technique would require a dedicated thread for every object requiring cleanup, doing nothing but waiting for the reference to be enqueued. This is as unscalable as any other thread-per-object model.
It may be apparent that I have talked myself in circles in this matter a few times now... if anyone holds the Ariadne's thread to this issue, I would love to see a phantom reference in a useful context.
Apologies if I confused the issue more than I clarified it.

Frame Maker 9 Cross References Question
Howdy,
I got two documents the original and a translated version of it. The original has a bunch of working cross references and it's all fine and dandy. The translated one on the other has a bunch of broken cross-references, chapter headers, headers in general and what not. Almost all of the "code" broke when the translator did it.
Either way, that's easy enough to fix it, I can just copy the working code from the original and paste into the translated document and it will generaelly fix the error.
Now for the question - Since my translated document is a couple of pages longer than the original due to the translation can I still copy of the cross references from the first document over, and it will be all fine and dandy?
Basically I didn't write either docuements I'm just fixing formatting and other errors, and I'm not entirely 100% how Frame Maker does it cross references are they based on a page number/paragraph parameters, or something like under X subheading go here and that's how it links.
TL;DR How do Cross refernces work in FM9? And if I have a translated doc longer than my original, can those same Cross references work in both docs?
Thanks much for any help/insight.
Dean,Almost all of the "code" broke when the translator did it.
They probably deleted the Cross-Ref Markers when over-typing the text. If Text Symbols were off during edit, that's pretty easy to do.
... and I'm not entirely 100% how Frame Maker does it cross references are they based on a page number/paragraph parameters, or something like under X subheading go here and that's how it links.
Unless you are Xref'ing a hand-created Marker, Frame auto-creates a Marker, of type "Cross-Ref" at the start of the target paragraph. It also auto creates an Mtext tag, which contains what appears to be a unique number string, the Paragraph Format name and the paragraph text (including any auto number). There is also a <Unique> tag with another unique number string.
When resolving references, my impression is that Frame first searches for the <Unique> number, and if not found, then for the Mtext string, and then possibly for the Mtext string without the leading number string.
If the translators do two things, I would expect the Xrefs to port:
Don't disturb Xref Markers. This can be tough, because it's sometimes hard to select text and not nab leading Markers, and because all Marker symbols look alike, and the Index markers do need to be messed with.
Don't translate text defined by Markers. That text will auto-translate from the source text at Update. -
Technical Reference question: Relationship between WIP Tables & INV Tables
Hi Community,
Due to my profile is more closer to the Financials Area than the Manufacturing and Work In Process Area, I want to leave the following question in the community, in order to see if anybody can give me an answer.
We want to modify a view created for its use in Discoverer. This view, retrieves the total number of units or kilograms that we have of all our items in all of our subinventory organizations, till submitted date. For all this itms, we want to know how many of them, and in which quantity should we depreciate them (is that to say, we categorized those items based on its antiquity in stock, to 6 months, 12 months, 18 months and more then 18 months). How we know the time range?, making a comparison between its last purchase date and its last sales date; and the result of that, with the submitted date.
This logic, works fine for all items added to our stock as a result of a Purchase Order and a Sales Order, cause in both operations, we can get the purchase date and the sales date; but for all of our items that we manufacture in our manufacturing process, all those items appears in the Discoverer Report, totally depreciated; is that to say, with an antiquity grater than 18 months. And in some cases that is correct, cause there are materials and items in stock since beginning implementation and migration from the old system, but for a huge number of them that is not correct, cause its stock is "constantly" up and down based on the manufacturing process or because its components are all of them purchased by a Purchase Order, but the final item get as a result of the manufacturing process, does not have this purchase date (does not inherit the first or last purchase date from any of its components), cause the only date that we can retrieve is the production date (transaction date) when the item was created.
So we want to include this production date in the logic of the query used to creation of the view which feed the discoverer report or to know the relationship between the WIP tables and INV tables (those where the items are reflected), in order to match the item, created in the manufacturing process, and the stock of that item in our subinventory organization.
Thanks in advance for your help and assistance.
LuisHello Experts, One of the Interview I faced a scenario,I have two tables T1,T2 and i have access to oracle and informatica .How can i know the relationship between two tables? Thankssirii

class A
A()
System.out.println("Inside A");
class OR
public static void main(String args[])
A obj_a=new A();//This create an Object of class A
A ref_a;//This create a Reference of class AWhat are the differences between an Object and a Reference of a class?new A() - creates the actual object.
Both obj_a and ref_a are references.
obj_a is referencing the object you created, and ref_a is not assigned yet. -
Question offsets - need to determine how to reference in formulas
I am using Crystal XI with a sequel database and have been unable to determine how to reference question offsets in a formula.
Example: Question 100 in the table is Appraisal Fee. However, question 100 has several offsets. Offset .01 is Appraisal Cost, Offset .02 is seller paid amount, Offset .03 is lender paid costs, etc.
The sequel database table contains question 100, but not entries for any off the offsets.
I need to reference the offsets in a Crystal Formula. Should I be able to do that without having the table updated to include entries for each offset? If so, helping me understand how would be greatly appreciated.Hi Diann,
Sounds like you need a big, ugly Case statement. If I'm understanding correctly, essentially you are trying to create a column with the offset label in it. The only way I can think of to do this is something like:
Create formula field called Offset, then define the formula simlar to below:
select
Case "Appraisal Cost" : "01"
Case "Seller Paid Amount" : "02"
Case "Lender Paid Costs" : "03"
Default : "99";
You could then use the Offset formul field as either a group in your report, or at least as a sort order for the records. You could also use it in other formulae.
Hope that helps!

I've seen cross reference questions, but none dealing with ID CC, which, I believe is 64-bit.
We've greatly expanded our use of cross-references with this new more power version with overall good success. However, ID still seems to insist on updating every cross-reference with every keystroke. What a pain.
I work with all book documents open to minimize this, but since it's across a network, it can still be pretty painful. In addition, some documents are used in multiple books so I use layers to control which cross-references are active any any given time.
It's getting very trying. Does anyone have experience with using 3rd party xref management software with ID CC?Hi Van,
I fear, I expressed myself not very clear. I try again.
We have DITA structured documents. However, lastest status often was saved in the FM document. The xml documents often are not representing the final status.
When I open the FM8 document in FM9 everything looks pretty good.
But: When I want to save the document as xml with FM9, I'm getting errors regarding the cross references.
The cross references which were created in FM8 - doesn't matter, if a valid xml document or a FM document - always look the same.
(BTW: I don't think that in structured documents cross references always refer to elemts with a unique ID.)
example from xml which was created with FM8:
<xref href = "#id08B4A0R30E9" type = "fm:Chapter">"..."</xref>
the only difference in the FM document is that the element is called fm-xref there, as it's not an external url.
in FM9 those cross references are totally different.
example from xml which was created in FM9:
<xref href = "#id08B4A0R30E9" class = "- topic/xref">"..."</xref>
When saving the FM documents with the cross references from the first example as xml in FM9 (we don't have FM8 anymore), I get an error that the attribute type is not defined.
When having a xml document that was last changed with FM8 and opening/ saving this with FM9, there is no error.
At the moment I do not know how to solve this issue.
And also I'm not sure weather the same problem might accour again with change from FM9 to FM10 or else.
It is a great effort to make new cross references just because we upgraded from FM8 to FM9. (And of course always at most inconvienent time.)
As we are thinking of upgrading to FM10, it would be good to know before, if there are any similar issues to expect.
Or if there is an fix for FM9 or FM10 to avoid this at all.

I have QuickTime 7.4.1 running on my G3 OS Panther and on my iMac OS Tiger.
Whenever it plays a movie on the Ge all I get is the sound and no picture.
On my iMac OS Tiger it runs ok.
I once installed Flip for Mac but deleted it. I searched for Flip for mac on my G3 and could not find any references to it except for some:
flip.jpg, flipbtn.gif, Flippers.tif.
Thanks for any advice.Hi Frank,
Try going to your HD/Library Folder/Internet Plugins and see if you have a QuickTime Plugin.webplugin folder there. If so, move this folder to the desktop. Try playing a QuickTime movie again and see if the video plays now. If not you can move this folder back to the Internet Plugins folder.
For future reference, questions concerning QuickTime can be placed in the QuickTime for Mac OS where there are many knowledgable users of the application there.
post back with any results,

I currently have 19000 emails and growing in my Mail application. I know this may seem stupid to have so many, but I run a small business and often have to quickly 'search' Mail to reference questions about previous communication with customers. I have 20-25 various email accounts for my business (i.e. Orders@, Shipping@, Sales@, Support@, Billing@, etc..., etc...) that come into Mail including a few gmail accounts.
I don't know of another way to quickly search my previous emails other than using the "search" feature in the Mail (top right of Mail) to find what I'm looking for. I've heard you can Archive mail but I'm not sure how I would quickly search to find something in a previous email that I need.
Will this many emails slow down my computer?
What else can I do with these emails to be able to reference them quickly when needed?
Thanks in advance.Ok so I had previously set up a few Smart Mailboxes but I really didn't know what I was doing. The messages from those specific emails are populating in the Smart Mailbox but it appears to just be a duplicate of the same INBOX email folder originally set up. I'm sure that's not the case, but I don't see any difference since my main Inboxes are specific to Shipping, Orders, Billing, etc... I can see how separating Orders by customer into Smart Mailboxes might benefit.
One thing to NOTE; I use my MacBook Pro and my iMac (soon to be new Mac Pro) switching from one to the other depending on whether I'm in office or out of office, so I want the emails readily available on both computers. I have them set up now so when I read an email on one computer it marks as read on the other. I'm processing lots of orders all the time so I need the luxury of both working as one, so to speak.
I also see where I can create a Mailbox "ON MY MAC". I don't know if this is what I need and will work for both computers or just the Smart Mailbox.
In order to avoid the "constant write/rewrite" of all my emails which do I need to do? (i'm assuming this adds to the memory and processing of the computer to constantly be doing this, which is what I'm wanting to cut down on).
And, if I could kindly ask, would you step me through what to do specifically?
AND... if I delete messages from my Inbox once I set up the folder you describe, do the emails still remain in the the place you are telling me to set up?
Many thanks. -
Session enabled RFC Web Service Fails & WSDL has enablesession=false
Please help Thanks in Advance
A stateful Webservice with 2 RFCs, consumed by a .NET application fails and the cause seems to be because of statelessness.
The call to 1st RFC succeeds and the call to the 2nd RFC fails with the below error message:
An exception with the type CX_SY_REF_IS_INITIAL occurred, but was neither handled locally,
nor declared in a RAISING clause.Dereferencing of the NULL reference"
Question:
1- Even though the "Session-Oriented Communication" is checked, the WSDL has EnableSession as false. Is there any special step to make it true?
2- Even though the SOA Manager says that the Session is enabled and SessionMode is Http Cookie, the HTTPFiddler doesn't show any cookie in the .NET side.
3- Are Web Service enabled HRXSS RFCs capable of performing Session Oriented Communication?
Eg. Can the RFCs HrxssPerInitPernr and HrxssPerReadP0002Us be called in a sequence?
service ws = new service();
ws.Credentials = new System.Net.NetworkCredential("abcd", "abcd");
System.Net.CookieContainer cookie1 = new System.Net.CookieContainer();

Exporting list to excel..order changes?
hello. thanks for the time and effort.
i'm a SharePoint 2013 noob. so forgive the simple question. we moved a team site from SharePoint 2010 to SharePoint 2013 and now a user is complaining that when they export to excel the list they see in IE the order gets changed around when it is exported
to Excel. They said it worked in SP 2010 where the list they saw on the team site was exported in the same order to Excel. It's an odd question that I wouldn't know where to start to look. Thanks again.
Also i did see that it cannot be exported when you open the site in Chrome due to ActiveX controls.Hi,
According to your post, my understanding is that you wanted to exporting list to excel. However, the orders were changed.
I recommend to create a page and add a Data View Web part using SPD on the page and then use SharePoint list as a Data source and add all items into the web part.
Then from Data view web part exported data to excel.
In addition, I recommend to modify view to remove the content type column.
Here are two similar blogs for your reference:
Question sequence is disordered when we export a survey list to excel
SharePoint 2010 Export to Excel 2010 Fails to Export All Fields in Some Views
The list cannot be exported when you open the site in Chrome due to ActiveX controls.
An ActiveX control is used in SharePoint 2013 to validate if you have Excel installed or not. You can try it out with Chrome on Windows -- it will fail.
Take a look at these ActiveX controls in use with SharePoint 2013:

Execute Shell Script through Demantra Workflow
Hi All ,
Can we execute shell script from Demantra Workflow ?
If yes where should we place the shell script file and wat should be the commandline command in the step .
We have the Demantra installed on a windows server and the workflow manager is on a linux server .
the batch file on the windows server can be executed through the secure shell from the linux server .
I am trying to achieve the same through thr demantra workflow
Appreciate any input on the same .
Thanks and regards
SuzyHi,
Shell script is not supported till Demantra 7.2.0.2 WF.
I have checked with Oracle team also and reply I got below for your reference:
QUESTION
*=========*
As per your details, shall we conclude like this:
*"only *.bat and *.exe files can be used in workflow. Demantra standard functionality doe*
*s not support shell script in workflow"*
ANSWER
*=======*
Hi ,
The Demantra standard functionality 7.2.0.2 does support shell script in workflow.
Thanks,
Asya
Please review the note#468071.1-Unable to Run EBS Workflows that Call EngineManager.exe in
You will find this note is referring to the Enhancement Request Bug 6644455-- ANALYTICAL ENGINE

Equivalence Operator - Oracle Text Search
Hi,
I am trying to use Equivalence Operator(=) as following,
SELECT SCORE (1), CLOB_COL
FROM TEST_CLOB
+WHERE CONTAINS (CLOB_COL, '({AIR}={WA@TER})', 1) > 0+
This seems to work fine for normal words, but when the word has any special characters(WA@TER) the equivalence operator throws the following error.
ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: Oracle Text error:
DRG-50921: EQUIV operand not a word or another EQUIV expression
DRG-50921: EQUIV operand not a word or another EQUIV expression
Please let me know if there is a way to escape the special characters.
The same query seem to work if i use "OR" operator instead of "Equivalence" but need to know whether it is possible to do it with "Equivalence" operator.
Thanks.865045 wrote:

Please keep google (and the Oracle documentation itself) in mind in the future, it's faster for you and less pollution to the forums for simple document reference questions like this. -
Error opening environment more than once
Hi,
I have two java classes which both need to access a container in an environment (in parallel). When the first class is instantiated the environment is opened successfully. However, when the second class subsequently attempts to open the same environment I get an error. (I do not want to close the env from the first class, while the second class does its thing)
The classes are Stylesheet extensions for an xmleditor which allows the stylesheet to look up item ID codes and display their names to the user by looking up the values in an xml file stored in a bdbxml container. There is a situation where two different objects need to have access to the environment at the same time - but its giving me an error when I instantiate the env for the second time - without having closed the first one)
Any help would by gratefully received
Kind Regards
Swami Kevala
I thought I could create multiple handles to the same environment?First is a class to encapsulate the environment (lifted mostly from the example code)
package org.isha.archives.bdbxml;
import java.io.*;
import java.util.*;
import com.sleepycat.db.*;
import com.sleepycat.dbxml.*;
//Class used to open and close a Berkeley DB environment
public class DbEnv
private Environment dbEnv_ = null;
private XmlManager mgr_ = null;
private boolean dbEnvIsOpen_ = false;
private File path2DbEnv_ = null;
public DbEnv(File path2DbEnv)
throws Throwable {
if (! path2DbEnv.isDirectory()) {
throw new Exception(path2DbEnv.getPath() +
" does not exist or is not a directory.");
EnvironmentConfig config = new EnvironmentConfig();
config.setCacheSize(50 * 1024 * 1024);
config.setAllowCreate(true);
config.setInitializeCache(true);
config.setTransactional(true);
config.setInitializeLocking(true);
config.setInitializeLogging(true);
config.setErrorStream(System.err);
config.setThreaded(true);
config.setRunRecovery(true);
config.setLogAutoRemove(true);
dbEnv_ = new Environment(path2DbEnv, config);
//Boolean used to know whether to close the environment
// when the cleanup() method is called.
dbEnvIsOpen_ = true;
path2DbEnv_ = path2DbEnv;
mgr_ = new XmlManager(dbEnv_, null);
//Returns the path to the database environment
public File getDbEnvPath() { return path2DbEnv_; }
//Returns the database environment encapsulated by this class.
public Environment getEnvironment() { return dbEnv_; }

public XmlManager getManager() { return mgr_; }
//Used to close the environment
public void cleanup() throws DatabaseException
if (dbEnvIsOpen_) {
dbEnv_.close();
dbEnvIsOpen_ = false;
Second is a class which encapsulates a container with a method for querying itself
package org.isha.archives.bdbxml;
import java.io.*;
import java.util.*;
import com.sleepycat.db.*;
import com.sleepycat.dbxml.*;

dbCont_ = new XmlContainer();
//Return the XmlContainer itself
public XmlContainer getContainer() { return dbCont_; }
//Returns the filename of the container
public String getFilename() { return cntr_; }
//Returns the XmlManager encapsulated by this class.
public XmlManager getManager() { return mgr_; }
//Used to close the container
public void close() throws DatabaseException
if (dbContainerIsOpen_) {
dbCont_.close();
dbContainerIsOpen_ = false;
//Used to open the container
public void open() {
try {
dbCont_ = mgr_.openContainer(cntr_, cfg_);
dbContainerIsOpen_ = true;
catch (Exception e) {
//Used to query the container
public String[] runQuery(String myQuery){
String [] queryOutput = null;
int counter = 0;
try {
XmlQueryContext context = mgr_.createQueryContext();
//Default namespace declaration does not work yet - this will work in the next release of BDB XML
//Until then we have to remove the namespace declaration from the reference.xml root element
//When this becomes available we can add the namespace declaration and uncomment the following line
//context.setNamespace("", defaultNS);
XmlResults results = mgr_.query(myQuery, context);
//Get the result set
queryOutput = new String[results.size()];
XmlValue value = results.next();
while (value != null)
queryOutput[counter] = value.asString().replaceAll("\\n", "").replaceAll(" "," ");
System.out.println(queryOutput[counter]);
counter ++;
value = results.next();
catch (Exception e) {
//Exception Handling code here
return queryOutput;
Now to explain what is happening:
When I open an xml document in xmlmind, it displays the document according to a prespecified CSS sheet. Sometimes the CSS rules alone are not sufficient to achieve the necessary effect/functionality, so the API allows you to write your own class, which contains methods to do what you want. As soon as the xml document is displayed, the CSS extension class gets instantiated.
Here is my extension class (called StyleSheetExtension). It contains a method called getKeywords. This method can then be invoked from within the CSS sheet, and is used to replace the keyword ID codes in the xml document with their corresponding keyword names - stored in an xml reference look-up document...

This instance (and consequently the newly created env and container objects) stay alive until the document is closed.
The xmlmind API also allows you to specify custom classes that will return a component that can be embedded in the stylesheet. (My class returns a JButton which - when clicked - brings up a dialog box which allows the user to specify /modify/addnew keywords to the selected text). As soon as the button is pressed I create a new env and container instance, for the duration of the pop-up window (since I have no way to pass the reference to the existing environment created by the StyleSheetExtension class.
Here's the class defn: (Here goes!) The env and container stuff is at the start of the nested-nested class called KpForm.

Used and allocated Shadow Copy Storage space is showing values in GB .
Hi All ,
This is an production issue and i need an urgent help on this case.
In my environment i am having exchange server 2013 in DAG extended with three sites.On that i am having two mailbox servers in the production site and one mailbox server in remaining two sites.
we have mounted all the mailbox databases in one production mailbox server.Those databases are present in LUN mapped to the production mailbox servers from SAN storage.
Issue :
Few of the mailbox databases are occupying too much of size on the LUN than it's original size.
Say for instance i have kept the mailbox database called "test" which is present on the LUN with the size of 190 GB.On that whole space the mailbox database is occupying only 100GB but on the diskmgmt and also on the explorer it is showing
only the free space as 17 GB.
Finally we have run the below mentioned command and found that the used and allocated shadow storage is occupying the size around 34 GB.
Attached snap for your reference :
Question : How to reclaim the space occupied by the shadow copy storage to the LUN ? If possible someone tell me why this issue is happening ?
Thanks & Regards S.NithyanandhamHi,
According to my research and technology, it’s caused by Volume Shadow Copy Service which is used to backup infrastructure for the Microsoft operation systems, as well as a mechanism for creating consistent point-in-time copies of data known as shadow copies.
We can use VssAdmin to create, delete, and list information about shadow copies. More details about Volume Shadow Copy Service, for your reference:

Besides, this issue may be related to Windows server. I recommend you to contact to Windows Server Team so that you can get more professional suggestions, please refer to:
