How to process Chinese when Oracle charset is US7ASCII

I'm using Oracle8.1.7 with charset in server is AMERICAN_AMERICA.US7ASCII. I can process Chinese with sqlplus, as well as the environment variable NLS_LANG in client is set as AMERICAN_AMERICA.US7ASCII. By with my java application,also with JBuilder's database pilot, I get the wrong character. I have tried thin driver and oci driver. The major difference is that with oci driver, the result
altered when the NLS_LANG is changed. But I can't get normal Chinese words until now. Could anyone tell me how can I handle this? BTW, the charset in DB server can't be changed because some other reason. Thanks in advance.

Thank you for your replying. Does that mean as the
database character set is US7ASCII, no Chinese
character will be saved into db correctlly at all? Depends on what you mean. Except for EBCDIC most (if not all) character sets (the computer term) use ascii as the base. There are certainly multi-byte chinese character sets that do that. So certainly parts of those will be correctly saved.
And it might also depend on exactly what "US7ASCII" means. In particular if it means that only 7 bits of each byte are saved then you have to use a mapping strategy. If it doesn't really mean that, and 8 bits are used, then multibyte character sets would be saved correctly because a multibyte chinese character set doesn't really do anything except add more 8 bit bytes.
But you still have to get it from java into the database. Java will map it into the character set regardless. One way around this might be to extract string values as bytes using a multibyte character set name (see the String.getBytes(String) method.) Then save that using Statement.setObject() into a string field.
At first, I also think Chinese character will lost it's
high bit when saved into ASCII DB. But another fact
puzzled me. Why sqlplus can save and retrive Chinese
correctlly? Could you please explain to me how does
sqlplus do that. Does it also execute some
transformation before saving into db.I couldn't help you there. It is possible that you just haven't tested enough - you haven't tested the entire character set. Or like I said, it is using an 8 bit ASCII character set and a chinese multibyte character set.
If you search this forum you will find some discussions about using foreign language character sets which might help. I don't recall any with this specific problem though.

How to install Chinese in Oracle Application Express 4.0?

hi,all
I want to know how to install Chinese in apex 4.0,though I know it's in the folder of "apex/builder/zh-cn",when I use a command like "@ load_zh-cn.sql",and it doesn't work.
and the path is >>>>>>>>>C:\oraclexe\apex\apex\builder
so what can i type in the terminal.
regards
hlee

You might want to go through the documentation here
To execute the SQL script you could either use the SQL script's full path
@C:\oraclexe\apex\apex\builder\load_zh-cn.sqlor
open Command prompt , move to that directory first and then run sqlplus
cd "C:\oraclexe\apex\apex\builder"
sqlplus sys/password
@load_zh-cn.sql

How solve ORA-04030: out of process memory when trying to allocate

i am facing problems in oracle 10g and after establishing 250 sessions
an error ocure
how solve ORA-04030: out of process memory when trying to allocate
how i can solve it.

The Oracle version and if Oracle and the OS are 32 or 64 bit versions affect whether or not the /3GB or /PAE flags come into play.
Also if pga_aggregate_target is not in use then the error generally means the userload is too large for available memory which could be because the previously mentioned switches are needed, because the user load is just to large for available resources, or that memory is being wasted by an excessive number of "dead" sessions. Again depending on the versions of the OS, Oracle, and the application space leaks could be an issue.
Bouncing will reclaim space lost to space leaks and clean up dead sessions but it is best to know why the problem exists before bouncing cause once you reboot you lose most of the information that will tell you what the cause of the problem is unless you make it a point to capture debugging information first.

How to convert Oracle charset database

I have a Oracle database which set charset "WE8ISO8859P1". how can I convert to "SJIS" charset that dont need create new database

You can't.
You can successfully convert an Oracle database's charset without database recreation if and only if 1) the original charset is a strict subset of the final charset (the letters in the set) and 2) the codepoints (the numbers that encode the letters) in the original charset don't change in the final charset and 3) all of the data in the database actually is encoded in the original charset (or at least is correctly encoded in the final charset). This is because this type of conversion is accomplished by simply slapping a new charest lable on the database as a whole; none of the binary values in the data get looked at, much less touched. If you "convert" a database and all three are not true, then some or all of your string data becomes complete and utter garbage.
For WE8ISO8859P1 to SJIS, both 1) and 2) are false.
3) becomes an issue because of what Oracle calls an optimization and I call a stupidity; when a database recieves string data from a client that asserts it's using the same charset, nothing checks that the data passed is actually in that charset; thus is it's trivially easy to get 8-bit data in a 7-bit US7ASCII database; it will read and write correctly until the day you try to convert to a superset of US7ASCII, such as UTF8. Then WHAM! Data corruption.
Oracle customers with support contracts can get a lot of documentation about character set conversions from the Metalink support site. Oracle also strongly recommends that customers file a support request for conversions (although someone who reads all the docs and understands character encoding and the NLS settings can muddle through on their own). Oracle also has lot of free documentation about globalization and character sets on the OTN site, which just requires a registration, but I'm not sure the nitty gritty details are there.
For non-subset conversions, the way to do it is to export the data, create a new database and import the data. Conversion to the new encoding will occur on import.
There is a utility, CSSCAN, that can be used to prepare for a conversion. It will scan the database for strings that will have difficulty converting.
Besides the possible issue of data that is outside of the original charset, it will also check for data that will be truncated on conversion. By default, the size specification of a VARCHAR2 in Oracle is the number of bytes; when a character is converted, it may expand the number of bytes that it requires, for example when switching form a 7 or 8 bit encoding to a 16 bit encoding. If enough characters in a value are expanded, the data exceeds the size of the column and is truncated or dropped (I forget). Recent Oracle versions lets you change from having the DB count size in bytes to counting size in characters; I don't yet know if this plays nice with imports with character set conversion (I'll know in a few months).

ADF how to display a processing page when executing large queries

ADF how to display a processing page when executing large queries
The ADF application that I have written currently has the following structure:
DataPage (search.jsp) that contains a form that the user enters their search criteria --> forward action (doSearch) --> DataAction (validate) that validates the inputted values --> forward action (success) --> DataAction (performSearch) that has a refresh method dragged on it, and an action that manually sets the itterator for the collection to -1 --> forward action (success) --> DataPage (results.jsp) that displays the results of the then (hopefully) populated collection.
I am not using a database, I am using a java collection to hold the data and the refresh method executes a query against an Autonomy Server that retrieves results in XML format.
The problem that I am experiencing is that sometimes a user may submit a query that is very large and this creates problems because the browser times out whilst waiting for results to be displayed, and as a result a JBO-29000 null pointer error is displayed.
I have previously got round this using Java Servlets where by when a processing servlet is called, it automatically redirects the browser to a processing page with an animation on it so that the user knows something is being processed. The processing page then recalls the servlet every 3seconds to see if the processing has been completed and if it has the forward to the appropriate results page.
Unfortunately I can not stop users entering large queries as the system requires users to be able to search in excess of 5 million documents on a regular basis.
I'd appreciate any help/suggestions that you may have regarding this matter as soon as possible so I can make the necessary amendments to the application prior to its pilot in a few weeks time.

Hi Steve,
After a few attempts - yes I have a hit a few snags.
I'll send you a copy of the example application that I am working on but this is what I have done so far.
I've taken a standard application that populates a simple java collection (not database driven) with the following structure:
DataPage --> DataAction (refresh Collection) -->DataPage
I have then added this code to the (refreshCollectionAction) DataAction
protected void invokeCustomMethod(DataActionContext ctx)
super.invokeCustomMethod(ctx);
HttpSession session = ctx.getHttpServletRequest().getSession();
Thread nominalSearch = (Thread)session.getAttribute("nominalSearch") ;
if (nominalSearch == null)
synchronized(this)
//create new instance of the thread
nominalSearch = new ns(ctx);
} //end of sychronized wrapper
session.setAttribute("nominalSearch", nominalSearch);
session.setAttribute("action", "nominalSearch");
nominalSearch.start();
System.err.println("started thread calling loading page");
ctx.setActionForward("loading.jsp");
else
if (nominalSearch.isAlive())
System.err.println("trying to call loading page");
ctx.setActionForward("loading.jsp");
else
System.err.println("trying to call results page");
ctx.setActionForward("success");
Created another class called ns.java:
package view;
import oracle.adf.controller.struts.actions.DataActionContext;
import oracle.adf.model.binding.DCIteratorBinding;
import oracle.adf.model.generic.DCRowSetIteratorImpl;
public class ns extends Thread
private DataActionContext ctx;
public ns(DataActionContext ctx)
this.ctx = ctx;
public void run()
System.err.println("START");
DCIteratorBinding b = ctx.getBindingContainer().findIteratorBinding("currentNominalCollectionIterator");
((DCRowSetIteratorImpl)b.getRowSetIterator()).rebuildIteratorUpto(-1);
//b.executeQuery();
System.err.println("END");
and added a loading.jsp page that calls a new dataAction called processing every second. The processing dataAction has the following code within it:
package view;
import javax.servlet.http.HttpSession;
import oracle.adf.controller.struts.actions.DataForwardAction;
import oracle.adf.controller.struts.actions.DataActionContext;
public class ProcessingAction extends DataForwardAction
protected void invokeCustomMethod(DataActionContext actionContext)
// TODO: Override this oracle.adf.controller.struts.actions.DataAction method
super.invokeCustomMethod(actionContext);
HttpSession session = actionContext.getHttpServletRequest().getSession();
String action = (String)session.getAttribute("action");
if (action.equalsIgnoreCase("nominalSearch"))
actionContext.setActionForward("refreshCollection.do");
I'd appreciate any help or guidance that you may have on this as I really need to implement a generic loading page that can be called by a number of actions within my application as soon as possible.
Thanks in advance for your help
David.

How to localize HumanTask names and process names of oracle BPM process ?

Anybody known how to localize HumanTask names and process names of oracle BPM process ?

Oracle Apex is an API, if that helps you understand / visualize. You do not start Apex process nor stop it.
When an Apex session starts it starts calling the API.
You can however start / stop the listener. It may be OHS, ApexListener and the J2EE container running it, OC4J or any other "server" that you are using.
The built-in EPG is something like an API again, you cannot start / stop it but you can disable/enable it with DBMS_XDB.SETHTTPPORT API.

How to process other task when reading the data from a file?

Hello,
I met a problem. I created a GUI to control the audio data processing. When the "Start" button is pressed, a block of data is read from the audio file and processed, then loop.But other buttons or method cannot be operated in that procession until all data is processed.
How to let the other methods work under that circumstance? Should I use multiple threads?
The relative code:
SourceDataLine line;
boolean stop = false;
// When press "Start" button, the following method is invoked:
public void play(){
line.start();
int bytesRead = 0;
byte[] dataBuf = new byte[7500];
while (bytesRead != -1& !stop)
try
bytesRead = audioInputStream.read(dataBuf, 0, dataBuf.length);
catch (IOException e)
e.printStackTrace();
if (bytesRead >= 0)
int bytesWritten = line.write(dataBuf, 0, bytesRead);
line.drain();
// When press "stop" button, this method is invoked.
public void stop(){
stop = true;
line.stop();
// When press "***" button, the following button is invoked:
public void ***(){
Many thanks.Looking forward to getting your answer.

You have to use a seperate thread :
Wheb you press the start button, you have to make sure a seperate thread is started :
Thread runner = new Thread(){
public void run(){
//Here comes your code which reads the file
runner.start();

How do I know when my unlock has been processed?

Hi all,
Sorry for what's probably a dumb question, but I can't find an answer anywhere.
I have an AT&T iPhone 4S, and I recently called them to request an unlock. Since it was on a business account while under contract, they had to submit a request directly to Apple instead of just using the web form. However, they told me that they never received anything from Apple during the process that would indicate that I'll be notified once the request has been approved. So from my understanding, completing the process on my end involves tethering to iTunes and restoring the phone - but how will I know when it's actually time for me to do that?
I should add: I am no longer with AT&T, or in touch with anyone else who is still on the account that I had been part of. So if anyone else on that old account gets notified, I won't know. And since I'm not with AT&T myself, I feel doubtful that they'd let me know.
Thanks for your help!
