How to create a file in memory and then store it in database

Hi Guys,
I'm wondering how could i create a file such a plain text or css styleshhet in runtime and then store this file in the database. I need to save them in the database cause the application doe not have write permission to filesystem.
Is that possible ? Can a file be created only in memory and saved in database instead of filesystem?
I'd appreciate your help on this.
Thanks a lot.

What i really need is to save information as a stylesheet into db. These information is input in a form and sent to a servlet. You have a servlet and in there you are creating data, lets say the data is representable as a string.
You have a database layer (however it is implemented) which takes data (string) and stores it as a blob presumably.
That is two distinct and completely separate processes.
The second has nothing to do with the first because the second doesn't care how the data is created. And you should write the code for the second and test it completely independent from the first (just as all of the database layer should be handled.)
As for the first you can use StringWriter, perhaps wrapping it in PrintWriter if you wish. Do whatever you want to put data in there. Be sure to close it, extract the string and then use it.
The only limitation to processing like this is that if the data gets too large (individually or due to number of threads) it could adversely impact the application.

How to create a file in memory and how to open it?

Hi All,
Warm greetings...
I bundle a file in encrypted form with my project's distribution. User may need to see this file while working on it. I want to load this file in memory, decrypt it there and then display its content to user in read only form.
Is there any way to do this.

And what happens if the OS swaps your application to hard drive while the user goes to lunch? Is that or is that not a problem?
In some business domains that is a problem and in others it isn't.

How to create OEMS JMS In-Memory and File-Based Persistence?

Anyone knows how to create OEMS JMS In-Memory and File-Based Persistence? Any help it is appreciated. I m working with Oracle BAM 11g TP4 and I want to test the capability of connecting directly to a JMS queue, and reading Oracle´s "complex" documentation I couldnt find the right way to make this happen.
tks

Hi Mario
This is explained in the soa developer's guide. Chapter 43 "Enterprise message source"should help you. You will find how to connect OEMS or JMS in-memory/file based to your BAM data objects with or without xpath transformation.
You can find sample of advanced XML formating in the 10g tech note: "Oracle BAM 10.1.3 configuration for BPEL 10.1.2 using JMS sensors" (useful even if you don't plan to use BPEL).
Anyway, if you plan to use BPEL, forget JMS and use the BAM adapter (chapter 42), it's quicker & easier.

How to create xml file from Oracle and sending the same xml file to an url

How to create xml file from Oracle and sending the same xml file to an url

SQL/XML (XMLElement, XMLForest, XMLAgg, etc) and UTL_HTTP.
Whether that works for you with the version of Oracle you have, your requirements, and needs is another story. A little detail goes a long way.

When pressing the "R" on the keyboard to record the following pop up - "Beta-only warning message-not to be localized Can't create record files please report" and then this "error occurred Result= -48" What does this mean?

When pressing the "R" key on the keyboard to record the following pops up - "Beta-only warning message-not to be localized. Can't create record file, Please Report" I press O.K. and this pops up - "Error occurred Result= -48". Can't figure out why. First time I have every had problems> What's up with this?

a -48 error is a duplicate filename.

How to create a page that tests and then creates a valid DB LINK connection

The problem is that I'd like to create a page that has all the necessary fields (name, host, port, etc) to create a database link just like the one in the SQL workshop - I'd prefer to have it done this way so as to limit the users from using SQL workshop. But i'd also like the DB Link tested before created.
I've tinkered around a bit and was able to create the database link using a page process that calls an execute immediate statement to add the database link using items in the form section, however I'm confused as to how I would test the connection before hand.

but rather the concept of a page that reads from table (maybe a "report?") to provide a result set of data which the user can click on a result to direct to another page.You are on the right track with the idea of an initial page with a report region listing your reports as links. Not sure from the provided information if this out of the box capability will meet your actual requirement, but try the Create Page wizard > New page > Form > Form on a Table with Report as a first approximation.
instead of creating unique individual pages for each of the 100 Oracle Reports, featuring the report's attributes (parameters, etc), what do I need to do just have one APEX page that dynamically reads from the table and builds the Region and its Items based on what's in the table?If this can't be handled using the built-in Form on a Table with Report design pattern, it sounds like it will be possible using a dynamic form generated using the [APEX_ITEM API|http://download.oracle.com/docs/cd/B28359_01/appdev.111/b32258/api.htm#BGBHDGAI] either as another report region or a PL/SQL Dynamic Content region.
Also, any reference books that you guys recommend on the ins/outs of APEX? [Pro Oracle Application Express|http://www.amazon.co.uk/gp/reader/159059827X/ref=sib_dp_pt#reader-link], the authors of which are active voices on this forum, is a good book. The forum itself is an unbelievable resource, as is the hosted service for learning and experiment at [apex.oracle.com|http://apex.oracle.com/i/index.html].

I am working in windows 7 and I am trying to enable the copy/paste and I can not find user.j file in the profile and I am not real sure how to create a file, I can create a folder .

I am trying to copy text from a word document and paste it into my web builder and it says that firefox does not support copy/paste from clipboard. Went to your site and it tells me to open the user.j file in my profile. This file does not exist and I am not real sure how to create that file so I can paste the fix from your site into it.

I went to that link and added to firefox add on but it still does not work. I went to the add on option button for this but it told me that my MYSIWG widget was disabled. Does this have something to do with it not working and if so how do you enable it.

How to Create a New Admin Account and Change Original to Standard Account?

I have a single user admin account that I set up when I got my PowerBook. Now I want to have two accounts with the new one being the admin account. This way I can leave most of the data files, email accounts, etc. with the old account and use the new one for personal data and admininistration. Then I could give out the password for the original account without fear that a user could change permissions and get access to the new account with the personal data. Can I create a new admin account and then change the original account to "Standard" instead of "admin"? What problems will this create?
PowerBook G4 Mac OS X (10.3.9)

i2:
Not sure if you are asking if or how. Templeton has
answered if. Here's how.
Apple Menu > System Prefs > Accounts. Click on the +
under User Options to create new account. Go to
Security and check box at bottom to make account
admin. You can take care of the other items, picture
etc, login options etc.
To make the other account Standard select the
account, go to Security and deselect box "Allow User
to Administer".
Hope this answers your questions.
Good luck.

How to create txt file in utf-8?

Hi,
if i create a txt file using vb in fdm, it is created with the ansi encoding. Is there any option how to create this file in utf-8?
Thx

Forms6i uses Oracle 8.0.6 client libraries. MetaLink Note 207303.1 lists supported client/server configurations, and the last database version supported with those libraries is Oracle 9.2. The only exception is made for e-Business Suite (Oracle Applications). Therefore, you configuration is not supported.
Anyway, Oracle 8.0.6 does not support AL32UTF8 well. You should select UTF8 as the database character set (not national character set!). You need to select a check box on DBCA interface (possibly unavailable in fast/default installation path) which allows you to see non-recommended character sets.

How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!

How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!
I want to know how to create a backup file (because I'm pretty new with itunes, and it's hard to use it for me still), how to store my app data/media/videos, etc. And how I can retrieve them back when I'm done with the app I tried on my friend's computer.
If anyone can help, it'd be great! Thank you so much!

Sure-glad to help you. You will not lose any data by changing synching to MacBook Pro from imac. You have set up Time Machine, right? that's how you'd do your backup, so I was told, and how I do my backup on my mac. You should be able to set a password for it. Save it. Your stuff should be saved there. So if you want to make your MacBook Pro your primary computer, I suppose, back up your stuff with Time machine, turn off Time machine on the iMac, turn it on on the new MacBook Pro, select the hard drive in your Time Capsule, enter your password, and do a backup from there. It might work, and it might take a while, but it should go. As for clogging the hard drive, I can't say. Depends how much stuff you have, and the hard drive's capacity. As for moving syncing from your iMac to your macbook pro, should be the same. Your phone uses iTunes to sync and so that data should be in the cloud. You can move your iTunes Library to your new Macbook pro
you should be able to sync your phone on your new MacBook Pro. Don't know if you can move the older backups yet-maybe try someone else, anyways,
This handy article from Apple explains how
How to move your iTunes library to a new computer - Apple Support''
don't forget to de-authorize your iMac if you don't want to play purchased stuff there
and re-authorize your new macBook Pro
time machine is an application, and should be found in the Applications folder. it is built in to OS X, so there is nothing else to buy. double click on it, get it going, choose the Hard drive in your Time capsule/Airport as your backup Time Machine and go for it. You should see a circle with an arrow on the top right hand of your screen (the Desktop), next to the bluetooth icon, and just after the wifi and eject key (looks sorta like a clock face). This will do automatic backups of your stuff.

How to create a file in the server?

Hi,
I'm making a webservice that has to generate a XML file, sign it using another webservice and return this XML. The problem is that i don't know how to create the file in the server throught webservice.
I use this code in the webservice to generate the XML and after I return the XML to client in a byte[]
 static void outputDocumentToFile(Document myDocument, String path) {
 //setup this like outputDocument
 try {
 // XMLOutputter outputter = new XMLOutputter(" ", true);
 XMLOutputter outputter = new XMLOutputter();
 //output to a file
 FileWriter writer = new FileWriter(path);
 outputter.output(myDocument, writer);
 writer.close();
 } catch(java.io.IOException e) {
 e.printStackTrace();
 }But the file is generated in the client-side, how can I generate the file in the server-side?
Thanks very much.

Well the File object doesn't create a file it's simply an abstract representation of file and directory pathnames.
You can try something like this:
<%
try
// get the path to the web server root
// I read somewhere not to use 'getRealPath' for some reason which I
// can't seem to remember :S Hopefull someone can enlighten us :)
String path = application.getRealPath("/project/jsp/demo.txt");
File file = new File(path);
PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter(file)));
writer.println("Hello World!");
writer.close();
catch (Exception e)
System.err.println(e.getMessage());
%>
Hope this helps :)

How to create temp files in temp tablespace

Dear all,
Due to outage of our SAN, we our out of production for the
last 3 days. By the grace of Almighty we have restored production by
database recovery from our standby backup. Since temp tablespace and
temp data files do not taken as backup for standby, now after recovery
we are getting abap dumps asking for temp_1 and temp_2 datafiles.
Please guide us how to create temp files. v$tablespace is showing tablespace PSAPTEMP but datafile are not there
Abap dumps are giving these errors as mentioned below
====================================================
The exception must either be prevented, caught within the procedure
"DATA_SELECTION"
"(FORM)", or declared in the procedure's RAISING clause.
To prevent the exception, note the following:
Database error text........: "ORA-01157: cannot identify/lock data file 256 -
see DBWR trace file#ORA-01110: data file 256:
'/oracle/SD1/sapdata4/temp_2/temp.data2'"
Internal call code.........: "[RSQL/FTCH/MARA ]"
===================================================
another one asking for
'/oracle/SD1/sapdata3/temp_1/temp.data1'"
Best Regards
Waqas

if you want to add a new tempfile to your TEMP Tablespace,you can do like that.
ALTER TABLESPACE <name of TEMP Tablespace> ADD TEMPFILE <pfad to the file_and_file name> SIZE <size>;
You can use also the options REUSE autoextend off or on .
e.g:
alter tablespace PSAPTEMP add tempfile '/oracle/SD1/sapdata4/temp_2/temp.data2' SIZE 1000K REUSE;
The directory temp_2 should exist.
Or you can use the BR*Tools to create a new datafile. Enter brtools and follow the instructions or menu.
More to TEMP Tablespaces see please following SAP notes:
659946 - FAQ: Temporary tablespaces
600513 - ORA-25153 after recovery due to missing tempfiles
and the Oracle Note:
160426.1: TEMPORARY Tablespaces : Tempfiles or Datafiles ?
I hope it helps.
