How to check whether java.sql.Connection has been dropped or not

Hi,
How can i check whether the connection is dropped from the database or not by using java.sql.Connection API.
Thanks

There's a few ways to check Connections, each with a different use:
(1) conn.isOpen()
(2) conn == null
(3) the last one is a little more involved and adds some overhead. You can run SELECT 1 FROM dual; (Oracle) or SELECT 1 (MSSQL) and check for exceptions.
The only way to check a connection, as far as I know, is to use it. That said, there must be a better way???

How to identify whether a TransientVO value has been changed or not on jsff

Hi
I have a TransientVO view object dragged onto jsff page. Is there any way to identify in backing bean or in Application Module to identify whether there is any attribute value has been modified or not?
Thanks in advance !!

Hi:
My understanding is that's ADF's internal business to keep track of RowSet changes. In your code, it's not expensive to explicitly call commit OperationBinding. When your code issue an explicit commit, ADF will check if a real commit necessary or not. If any row or attribute changed, a real commit will happen.
If your application really want to get notified when any attribute changes, and you feel it too much to implement a valueChangeListener for every inputText, you should try a more generic one: rowUpdated(). I never use this one, but according to the manual, your probably can set a flag in your overwritten rowUpdated to flag an attribute value change when it happens.
But I really recommend you simply issue a commit and let ADF decide the necessity of a real commit. If you are really interested in which specific field changes, to me you have only 2 options, 1 is to do valueChangeListener, the other is try to figure out if rowUpdated() helps.
If you feel my answer helps, please mark it as 'helpful'; If it is correct, please mark it as 'correct'.

We are a retail shop which has a copy of AppleCare Protection plan. The box is not sealed. How can I tell if the product has been registered or not.

Since the only thing needed in that box is the small piece of paper with the (very long) registration code on it (usually found inside the booklet), see if that is actually there and, if it is, call Apple at 800-275-2273 and ask to be transferred to the Applecare department. Here is the link to the Applecare plan - just in case you may need it, see the fax numbers listed under para. 9 (Cancellation).

BC4J - How can I get java.sql.Connection ?

Hi,
I am using BC4J for my Application and want to get the java.sql.Connection from ApplicationModule or from anywhere such that I can use the same connection as in ApplicaitonModule, to do some work in the database.
I tried to get it from the SessionInfo :
sessioninfo.getConnectionInfo();
but this returns me oracle.dacf.dataset.connections.Connection
How can I convert this to java.sql.Connection?
Or Is there any other means to get hold of sql.Connection?
Any help would be appreciated.
TIA

Thanks for this reply.. but
I need java.sql.Connection to call a stored procedure in Oracle database and I have to pass oracle.sql.ARRAY to it.
My Stored Procedure looks like:
create or replace PROCEDURE updateRevenueNetworkInfo(revid varchar2, netids Varchar32Array)
where 'Varchar32Array' is my own datatype in the database which is mapped to oracle.sql.ARRAY object in java.
And in order to create oracle.sql.ARRAY I need java.sql.Connection as shown below
oracle.sql.ARRAY pTable = new oracle.sql.ARRAY(desc, connection, netidarray);
I am executing my stored procedure like this:
ArrayDescriptor desc = null; CallableStatement cs = null;
String[] netidarray = {"00-AOL-T1-N003"};
desc = ArrayDescriptor.createDescriptor("VARCHAR32ARRAY", conn);
oracle.sql.ARRAY pTable = new ARRAY(desc, connection, netidarray);
cs = conn.prepareCall( "BEGIN updaterevenuenetworkinfo(?,?); END;" );
((OracleCallableStatement)cs).setString(1,"00-AOL-T1-R3");
((OracleCallableStatement)cs).setArray(2, pTable);
cs.execute();
Is there any way of getting java.sql.Connection such that I can use the same connection as in the ApplicationModule?
OR Is there any other way of passing Array of Strings to a stored procedure in the database?
Thanks for the help.

Is there a way to check whether an Excel file has a header or not?

Hi!
I'm currently using POI Utility to read and write Excel files.
You normally use the HasHeaderRow = true / false to specify whether the file has a header or not.
Now, let's say I have a program that needs to read Excel files from a directory, some have headers, some don't.
Is there a way to know dynamically whether a header has been defined or not?
Then, for those having headers, the flag will be set as true, while for those which don't have any header, the flag will be set as false.
E.g.

    <cfset objPOI = CreateObject(
        "component",
        "POIUtility"
        ).Init()
        />

<cfset currentDirectory = GetDirectoryFromPath(GetTemplatePath()) & "newDir">

<cfif DirectoryExists(variables.currentDirectory)>
     
     <cfdirectory action="list" directory="#variables.currentDirectory#" type="file" filter="*.xls" name="qDirectory">
     
     <cfif variables.qDirectory.recordcount gt 0>
          
     <cfloop query="variables.qDirectory">
               
                    IF headerExists THEN
                         headerFlag = true
                    ELSE
                         headerFlag = false
                    END IF
               
            <cfset objSheet = objPOI.ReadExcel(FilePath = #variables.qDirectory.name#, HasHeaderRow = #variables.headerFlag#, SheetIndex = 0) />
          </cfloop>
     </cfif>
</cfif>
Any help would be most welcome.
Thanks and regards,
Yogesh Mahadnac

Hi cfSearching,
Many thanks for your reply! I really do appreciate!
However, I've still got 1 more question for you.
At the moment, I'm using POI and sometimes cfx_Excel2Query to read Excel files.
In both cases, you have to specify whether the first row is a header.
How would you read the Excel file to check whether the 1st row is the header?
I've tried using cffile, but I get all sorts of "garbage"
        <cffile action="read" file="#variables.filename#" variable="xlsResult">
        <cfloop index="i" list="#variables.xlsResult#" delimiters="#chr(13)#&#chr(10)#">
            <cfif variables.i eq 1>
                <cfoutput>
                    Test 1st Row: #trim(replacenocase(listgetat(variables.i,1,","),'"',"","All"))#
                </cfoutput>
            </cfif>
        </cfloop>
I get the following output:
ÐÏ à¡± á��.... etc etc
I'd be very much grateful if you could please advise on the latter at your earliest convenience.
Thanks and best regards,

How to check the sales order that has been PGI from a range of dates.

Hi SAP Gurus,
I have a query on how can I check the sales order that has been PGI from a range of dates in SAP?
Thanks,
Madelyn

Dear Madelyn
Go to VA05, give the date range and execute. List of sale orders will be generated. There you can see a tab "Status" in which, the status would be like
- Not delivered
- Partially delivered
So based on this, you can decide whether the order is still open or completed.
thanks

How to check whether a char string is in uppercase or not

Hi,
I know how to convert strings to change strings to uppercase or lowercase, but is there any function to check, beforehand, if the field is in uppercase, for instance ? The intention here is simply to spare processing in situations where the string is already in uppercase, and thus not needing any further processing (given I want to turn the string into uppercase.)
Thanks in advance,
Avraham

Hi Avraham ,
To check whether the string is in upper case or not use CA keyward.
To check try the following code ---
DATA : W_STRING(5) TYPE C,
W_ABCDE(26) TYPE C VALUE 'abcdefghijklmnopqrstuvwxyz'.
w_string = 'abcd'.
IF W_STRING CA W_ABCDE.
TRANSLATE w_string TO UPPER CASE.
ELSE.
MESSAGE 'It is a uppercase string' TYPE 'S'.
ENDIF.
Try this link this will definitely help you -

How to check remotely that a PC has been restarted after Labview Runtime 2011 has been installed on it?

Hello,
I am deploying a Labview 2011 application on 150 XP-machines in various plants worldwide. Currently all machines still have an old Labview 8.21 runtime (+old DAQmx). I have sent a procedure to my colleagues in the plants so that they install the new runtime (+ new DAQmx). On my side I have built a code to check from my Pc if a certain registry key is present on the 150 PCs which tells me that the new installer ran or not.
The key that I found is:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Installer\Products\1C5E801AE54C4AE43A59FC169F95CA28]
"ProductName"="NI-DAQmx MAX Configuration Support 9.3.5"
"PackageCode"="61EEAEC207A28A842B3341ED6809453D"
"Language"=dword:00000009
"Version"=dword:0923c001
"Assignment"=dword:00000001
"AdvertiseFlags"=dword:00000184
"InstanceType"=dword:00000000
"AuthorizedLUAApp"=dword:00000000
"Clients"=hex(7):3a,00,00,00,00,00
This works well but it does not tell me that the PC has restarted after the installer has been run. If I do not restart the PC and try to execute my Labview 2011 executable I get a long error message (NIDAQmx not registered,...).
As it seems difficult to get the properties of a key to know when it was installed I was rather leaning towards checking if a certain DLL (?) has been registered or not. But it is just a vague idea and I do not know how to put that in place.
I am attaching the current code that I have and that works well but cannot make the difference between Labview 2011 runtime installed and PC restarted or not.
Thanks for the help

You might look for a file that would be created as part of installation to determine the install date/time (ini or other support file created as part of runtime install)
Combine that with a query of the station's uptime and you could calculate if the station has been up longer than the time since the install. Not perfect, but should be possible...

How to check whether Java 3d is using hardware acceleration?

Hi
I just started looking into Java3d api. I am going through the tutorial examples. When I run it on Windows with JDK1.4.2, the app runs, but taskmanager shows cpu usage is around 55% of my 3GHz Intel processor.
I am sending the following VM parameters
-Djava.library.path=C:\progra~1\Java\Java3D\bin -Dj3d.rend=ogl -Dj3d.debug=true
I tried Direct3D as well by passing -Dj3d.rend=d3d. I don't see much difference in cpu usage. The sample I am playing is the one where you create a ColorCube and rotate it on a timeline. Pretty straight forward code taken from the tutorial.
I am wondering
a) Why is my cpu at 55% if it is using h/w acceleration?
b) Is there any way to find out whether Java is using software renderer vs h/w renderer.
I used sys internals processexp tool to look at the stack of java thread that is spinning the cube. I don't see any references to opengl or j3d dlls in the call stack.
I appreciate ur help.
Thanks

There isnt any other way except for doing a Java Callout. In the callout method you can access the Domain/Server MBean for the information that you seek. Based on the callout result you can go ahead with the logic in your PS..

How to check if an SQL profile is being used or not?

Hi,
We have a couple of SQL profiles and outlines in the database. There has been a couple of code changes and it is now difficult to keep track if an SQL profile or an Outline is still being used? Is there any way to find that?
Thanks in advance

Find the entry corresponding to the SQL statement you are reviewing in V$SQL. Look at OUTLINE_CATEGORY and SQL_PROFILE columns. NULL indicates that no Outline/Profile was used.

How to check whether a SMTP server is supporting Authentication or not

Hi All,
We are using Java Mail API 1.3.1/1.3.2 to send the messages. some of the SMTP servers that we use are supporting authentication and some of them are not.
As the SMTPTransport.supportsAuthentication() is not available only in Java mail API 1.4.1, we are identifying the SMTP server whether it is supporting authentication or not in the following way.
Socket clientSocket = null;
InetSocketAddress socketAddress = null;
OutputStream outStream = null;
InputStream inStream = null;
InputStreamReader inReader = null;
OutputStreamWriter outWritter = null;
try
clientSocket = new Socket();
socketAddress = new InetSocketAddress(host, port);
clientSocket.connect(socketAddress, timeout*1000); // convert timeout from second to miliseconds
// 1: now try to execute the given command by passing that on Out-Socket
outStream = clientSocket.getOutputStream();
outWritter = new OutputStreamWriter(outStream);
outWritter.write("ehlo localhost" +"\n");
outWritter.flush();
// 2:Read output of above command
inStream = clientSocket.getInputStream();
inReader = new InputStreamReader(inStream);
// This array limit would be fine to get "AUTH" extension of smtp server.
char[] arr = new char[16384];
StringBuilder strBuilder = new StringBuilder();
inReader.read(arr);
for(int i=0; i< arr.length; i++)
strBuilder.append(arr);
System.out.println(METHOD_NAME + "SMTP server response for ehlo localhost command ->"+strBuilder.toString());
// The output EHLO command comes like below :
// ehlo localhost
// 250-ap9058pc.us.oracle.com Hello ap614ses.us.oracle.com [130.35.33.43], pleased to meet you
// 250-ENHANCEDSTATUSCODES
// 250-PIPELINING
// 250-8BITMIME
// 250-SIZE
// 250-DSN
// 250-ETRN
// 250-AUTH GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN
// Since for XATUH ( like internal IP),
// we are not sure, so just checking for AUTH capability.
supported = strBuilder.indexOf("250-AUTH") >=0? true : false;
As shown in above code, we are issuing 'ehlo localhost' command to SMTP server, if the response i. 'strBuilder' contains '250-AUTH' then we are assuming that it is supporting authentication.
But for one SMTP server the 'strBuilder' value is showing as '220 mail.durofelguera.com ESMTP Service (Lotus Domino Release 8.5.2) ready at Thu, 16 Feb 2012 13:57:20 +0100' only which is socket connection output but not 'ehlo localhost' command output.
where as the telnet test output is showing correct only as below

The question is why the 'strBuilder' is not showing 'ehlo localhost' conad output where as the telnet test results are showing correctly, what is going wrong here?
Is there any other way to check that whether SMTP server is supporting authentication or not?
Edited by: sarojak on Feb 19, 2012 10:11 PM

There are so many things wrong with your code, it's hard to know where to start...
Basically, the problem is not as simple as you think it is.
For example, some servers might not allow authentication until you've issued
the STARTTLS command.
These days, essentially all servers allow authentication. You're probably better
off just assuming the server supports.
