Right/best method to open and close form?

When i click a button from FormA, it open FormC and it should be the same with button from FormB-used to open the same FormC but it doesn't.
this happen when i previously open FormC from FormA before opening it in FormB.
I use setvisible(true) to open form and setvisible(false) to close the form and this doesn't seem right..
i use exactly the same method as shown in Creating Swing Clients for Business Components Tutorial
anyone can help? i'm new with Java n Jdeveloper...
Thank You..

Fatima,
this question is best answered in teh JDeveloper forum on OTN because this Forum is for Oracle Forms. You can start and hide forms in Java using setVisible(true|false), howvere, this doesn't release the hanlde to the data bound.
In the HowTo setcion of the otn.oracle.com/products/jdev there exist a document "How Do I dynamically Change the Binding of a View Object to JClient Panel?"
This explains how you work with RowSet Iterators to reuse forms.

What is the better way to open and close connection in bean

Hello, may i ask about the best way to open and close the connection?
At the first, the connection code is store in Conn class bean. The JSP page will call a method in Process bean to process the query and update of database. the Process bean is using th Conn to connect to database.
In my process bean, it have a method for each type of sql like select, insert, update, and delete for each tables. Each method will call the Conn to open and close the connection. The jsp page can simply call a method retrieve or update records.
However, when calling the processUpdate method, it is a method that update a group of tables base on the query result of another group of tables and calculation. If I calling the query method in the same bean file, it will open and close the connection many times (more than 1000 times). After open and close the connection several times, the connection to mySQL will be fail.
Currently, i include 2 method in Process that is only calling the Conn to open the connection and close connection. When calling the openConnection method, it will also set the boolean connected in the class to true and call Conn to open connection. When calling the closeConnection method, it will also set the boolean connected in the class to false and call Conn to close connection.
After that, i add some change to the query method which is when the connected is false, it will open the connection by calling the Conn and close the connection themself. If the connected is true, it will not call the Conn to open and close the connection because it already connected to the database.
Now, i when i calling the query method in jsp, it can open the connection and close the connection individually. When i call the processUpdate in the jsp, this method will calling the openConnection before calling the query and calling closeConnection at the end. It not only faster the process(less open and close), it also no cause the connect to mySQL fail error again. However, it also make the coding in the bean file more longer and complex.
Is there have any better solution?

Use connection pooling. This will put the connection management in the hands of the webserver, not your code. Check out this post:

Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels. Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer. I have a pretty simple system with only a few plug-ins, which are usually not in operation. I have 12GB of RAM in my Windows 7 PC. I could illustrate these problems with screen shots if you would tell me how to submit screen shots. Otherwise I will try to describe the problems in words.
The problem is clearly cumulative, growing worse as usage time passes. Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond. In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
To experiment I created a new catalog of 1100 images. After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data. (I have a screen shot to show this.) CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong. I could also send screen shots of this data.
At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR. This is not normal. I hope you can find the cause, and then the solution. If you would like to see my screen shots, tell me how to submit them.

Pages 09 document; open and close many times; right way with Lion?

I have a 106 page document that increases in size on a daily basis. With OS 10.7, iWork/Pages 09 on my new, iMac, it's common that I lose as much as two sentences after the document is closed and re opened. After 10.7 was installed the document was closed using Command - S, and subsequently closed by pulling down File and selecting Close. - Not the way to close; the red button was so easy with 10.6. IS UNINSTALLING LION THE BEST SOLUTION?
And yes, I've read the sorry jibberish in the Pages 09 manual - which doesn't say how to open and close repeatedly a document with Pages 09.
So, with the Lion - the worst ever of spending $30, is it necessary to do a Command S every time you close? And what exactly is necessary each time you close a document using Pages 09 and Lion? - And about Auto Save; well, what about Auto Save? - The Lion means well for something other than common, understandable, text production. -- How about a separate application of Appleworks for text producers like me?

The red button is always available under 10.7 (or 10.7.1)
Under 10.7, press cmd + S once when you create the document.
After that, the system automatically save your changes.
No need for cmd + S.
To close the document we may use :
the red button
cmd + W
File > Close
as it was with older systems.

IE open and close immediately. Can't fix using many methods.

A user reports that can't use IE 8 suddenly.
His PC is Windows 7 Pro sp1 and using Internet Explorer 8.
Don't know what he did before and he ever tried restore to previous point but no help.
I've tried the following.
1. http://support.microsoft.com/kb/967896
   Reset Internet Explorer to its default settings or
   Uninstall and then reinstall Internet Explorer through Turning on/ off windows features.
2. Use other user like Administrator to open IE. But result is same
3. Upgrade to IE 11. Still open and close immediately only.
   Repeat step 1 but still not solve.
4. Downloaded IE 11 and installed manually but it stated that IE 11 was installed. (Had turned off IE to uninstall it through Turning on/ off windows features)
Asked him to use Chrome but some websites need IE. So he must use IE too.
Please advise that how to fix it.
Hope not need to re-install OS.
Many thnaks.

1. Are there any traces in Event logs?
2. Try to delete history in IE
3. Try to disable add-ons.
4. If nothing helps, analyze your system with Process Monitor and Process Explorer. Check which programs starts with Autoruns (all programs are from Sysinternals)

Trackpad is presenting a bug to open and close windows, mission control, and to move/roll the application (App) up and down.

Totally out of the blue, my trackpad is presenting a "bug". Every time that I try to open and close my mission control, or in the moments that I move / roll up and downs the Applications Screen, my Mac freezes for less than a second.
It never suffered any damage (NEVER!)! I am feeling very frustrated because I have no idea about what could cause such problem.
My MacBook Air is running OS X 10.9.5.
Any help will be very welcome!

Well, it all really depends on the custom program and how it was written. Does it have an ActiveX interface? If it does, than that's the easiest way to go. If you put an automation refnum on the fron panel, you can right click and it and choose Select ActiveX Class>Browse. The browser will list all of the ActiveX type libraries that are registered on your system. If you can find one that refers to your custom program, then you should be able to use it's methods and properties to control. If it does not have an ActiveX interface, then things get much more difficult.

When to open and close database connection

im trying to connect to a oracle database using servlets
when should i open and close the connection
it works fine when i do both in the doPost() method
but when i tried to open connection in init() methd .. it doesnt seem to work
what should i do...
the connection is initialised in the init() method but is null in the doPost() method

1:
without seeing the code i would say the the connection is null
because you are storing it as a servlet class variable which is
not thread safe.
2:
The best way to do it using connection pooling
detailed docs on the tomcat website
3:
if you are not using connection pooling, then
open and close the connection in the do* method
or
use init() to place the connection in the servletconfig
and close in destroy() and use synching to access

Open and Close Posting Periods - 0B52 (FICO)

Dear Friend,
It will be much appreciated if you can help me with the below question.
What are the years to be mentioned in the year columns (_Underlined below_) in the Open and Close Posting Period (0B52) for the Fiscal Year 2011- 2012.
i.e., From Period 1 (1), Year (____), To Period (12), Year (____), From Period 2 (13), Year (_____), To Period (16), Year (____).
What is the significance of these years.
Thanks in advance,
Kiran RD.
Moderator: Please, avoid asking basic questions

Hi:
The column on the right From to TO is for special period opening and closing and columns on the left are for normal period opening and closing. If your fiscal year starts from January then for keeping open October period only and closing other , you will have to maintain all 10 in from and to along with year 2011 against account type A,S,K,D,M... I hope it will help you.
Regards

Open and close data input in DP.

Hi,
We have two periods in the future (actual and next) and we need open and close
actual year for input with macros.
We have built two macros to open and close actual year for input. The macro
to close the input is working OK (COL_INPUT( 0 )). the macro to open the input (COL_INPUT( 1 )) works OK too,
but the color doesn´t change, It goes on in grey color instead of white color.
We have used some operators (ROW_BG(), ROW_FG()...) to try to change the color but doesn´t change.
Did you Know how to bulid the macro to open actual year changing to white color?
Thanks in advance.
Raúl.

do you mean it is grey but you can still enter data?
check what your "input from" date is on the planning book design(data view tab)
I have seen this happen too... But, since you are using the column input macro you can let your input from be right from the beginning and use the macro to make it open and closed at the relevant years(means you set the column_input (0) for history too
the KF that should not be edited is set in the setting "output only"

Hi Guddan,
I created a RFC having a query which is taking a long time to execute. So i want to close RFC connection with portals which is via java connector(JCO) before that query and open the connction again after that query.
I guess i will need to understand your requirement a little more in detail, as i understand you have an RFC which has a query within to fetch some data and is taking a long time to do so. In the meantime you don't want to keep the connection open?
My question would be, Is the role of this RFC to only execute the query and fetch the data or does it do something else?
If it does other things and these are independent of the query execution, then you can span a parallel call within the RFC to execute the query and in the meantime the RFC does the other things (or vice versa) hence reducing the overall time taken.
If the sole purpose of this RFC is to execute the query, then you will not be able(i mean to say there is no simple and direct way of doing this) to close the connection after the Query is started and re-establish the connection after its execution, for a simple reason that - how will you know if the query has completed it's execution, so that you can establish the connection back.
Alternate solutions, make this a two way asynchronous call, 1) You invoke the RFC asynchronously and close the connection, the RFC in turn will execute the query and transfer the data to JCO via another RFC call.
If this needs to be a synchronous call, then you will need to optimize the query to its best.

Chen

[bdb bug]repeatly open and close db may cause memory leak

my test code is very simple :
char *filename = "xxx.db";
char *dbname = "xxx";
for( ; ;)
DB *dbp;
DB_TXN *txnp;
db_create(&dbp,dbenvp, 0);
dbenvp->txn_begin(dbenvp, NULL, &txnp, 0);
ret = dbp->open(dbp, txnp, filename, dbname, DB_BTREE, DB_CREATE, 0);
if(ret != 0)
printf("failed to open db:%s\n",db_strerror(ret));
return 0;
txnp->commit(txnp, 0);
dbp->close(dbp, DB_NOSYNC);
I try to run my test program for a long time opening and closing db repeatly, then use the PS command and find the RSS is increasing slowly:
ps -va
PID TTY STAT TIME MAJFL TRS DRS RSS %MEM COMMAND
1986 pts/0 S 0:00 466 588 4999 980 0.3 -bash
2615 pts/0 R 0:01 588 2 5141 2500 0.9 ./test
after a few minutes：

I had read bdb's source code before, so i tried to debug it for about a week and found something like a bug:
If open a db with both filename and dbname, bdb will open a db handle for master db and a db handle for subdb,
both of the two handle will get an fileid by a internal api called __dbreg_get_id, however, just the subdb's id will be
return to bdb's log region by calling __dbreg_pop_id. It leads to a id leak if I tried to open and close the db
repeatly, as a result， __dbreg_add_dbentry will call realloc repeatly to enlarge the dbentry area, this seens to be
the reason for RSS increasing.
Is it not a BUG?
sorry for my pool english :)

I have tested my program using Oracle Berkeley DB release 4.8.26 and 4.7.25 in redhat 9.0 (Kernel 2.4.20-8smp on an i686) and AIX Version 5.
The problem is easy to be reproduced by calling the open method of db handle with both filename and dbname being specified and calling the close method.
My program is very simple:
#include <stdlib.h>
#include <stdio.h>
#include <sys/time.h>
#include "db.h"
int main(int argc, char * argv[])
int ret, count;
DB_ENV *dbenvp;
char * filename = "test.dbf";
char * dbname = "test";
db_env_create(&dbenvp, 0);
dbenvp->open(dbenvp, "/home/bdb/code/test/env",DB_CREATE|DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_TXN|DB_INIT_MPOOL, 0);
for(count = 0 ; count < 10000000 ; count++)
DB *dbp;
DB_TXN *txnp;
db_create(&dbp,dbenvp, 0);
dbenvp->txn_begin(dbenvp, NULL, &txnp, 0);
ret = dbp->open(dbp, txnp, filename, dbname, DB_BTREE, DB_CREATE, 0);
if(ret != 0)
printf("failed to open db:%s\n",db_strerror(ret));
return 0;
txnp->commit(txnp, 0);
dbp->close(dbp, DB_NOSYNC);
dbenvp->close(dbenvp, 0);
return 0;
DB_CONFIG is like below:
set_cachesize 0 20000 0
set_flags db_auto_commit
set_flags db_txn_nosync
set_flags db_log_inmemory
set_lk_detect db_lock_minlocks

OB52 : open and close FI period by sales office

Dear experts,
I have a client who wants to open and close FI period by sales office.
After some researches, I find that itu2019s only possible to create the variants by FI company.
But what kind of solution I could suggest to the client ?
Thanks in advance for your help.
Best Regards.
Nathalie

hi
in ob52, you can define periods by account type i.e. A,K,D,M,S.
in your case if your sales office shall cater to Customers, you can specify those particular Account codes.
here i assume that a sales office shall cater to only certain group of customer accounts.
thanks

Is there a remote app that will let me open and close programs on my iMac

Hi There,
I know that I can use the Apple Inc "Remote App" to control my iTunes on my iMac - and I really like it for when I am not right at my computer, but I have to have iTunes open on my iMac before I can use it which is a bit of a pain to have to think "Am I going to use iTunes today?" or to run off to my office at the other end of my house when I decide I want music through my speakers and so my question is thus.
Is there a remote app that I can download for iPhone or even iPad lets you open and close programs on your iMac when you are not actually sitting at it. So say I want to open iTunes on my iMac i would do the following
1: Open the remote app on my device (either iPhone or iPad)
2: See a representation of iMac screen on that device (cut down for iPhone)
3: Chose the program I want (iTunes in this case) and it will open on my iMac allowing me to begin using the program remotely on my remote device.
I am not talking about remote desktop or anything here (I don't want to do complicated things on it) just be able to open programs like iTunes so I can have the music play through my home speaker system without having to have all of my programs already running on my mac incase I decide to use them
