BUG: retrieving NCHAR value using ViewObject returns "???" with OCI driver

Hi,
after upgrading JDeveloper to 10.1.3.1 we cannot use OCI JDBC drivers, because they don't work correctly - characters, that do not exist in database character set (EE8ISO8859P2 in our case) are converted to "?". Thin driver works well. We need to use OCI, because we had some issues with RAC with thin driver.
Test case is easy: create table with NCHAR column, populate with unicode data, create ViewObject to select from this table and it will work only with THIN and not with OCI driver. This worked well with 10.1.3.0. When I tried to directly connect to DB and select that table using java.sql.Statement, it worked with both drivers, that's why I suspect the mechanics inside ADF BC.
I logged a SR for this in Metalink, but try this way as well, for someone else could hit the same problem.
Thanks for any help,
Viliam

Is it possible to working in Java Stored Procedures with OCI driver?

Hello ALL.
Could you help me...
Is it possible to working in Java Stored Procedures with OCI driver?
I want to try to do some workaround...
I need to work with following parametrs from Java Stored Procedures:
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
String url = null;
url = "jdbc:oracle:oci:@TEST";
conn = DriverManager.getConnection (url,"scott","tiger");
Is it possible?
I tried but I have errors...
Please, help me!
Thanks

You cannot call OCI functions directly from PL/SQL. You could, of course, write an external procedure that made OCI calls, though you could also write an external procedure in Java. I'm guessing the documentation is trying to convey this same information-- you would need an external procedure that used OCI if you wanted to use the old-school interfaces for LONG and LOB data types. If you converted to using LOBs rather than LONGs, you could do everything in PL/SQL.

Retrieving the value using formatted search

Hi everyone. I have a question regarding on how I can get the value of the user-defined field in the title of a marketing document. I would like to get the value using formatted search and sql query.
Here's the format I am currently using.
$[$ <Item>.<Pane>.<Variable>]
Is my format correct? Thanks.
Regards,
Omann

Hi Omann,
You can refer to fields in an entry screen using the syntax
$[Table name.Field name]
The table name is the name of the table belonging to the entry screen, for example, OINV for the A/R invoice entry screen.
You can also use the fieldu2019s item number and fieldu2019s column number to refer to a field on the entry screen. By doing this, the query applies to all document entry screens. The syntax is then
$[$Fieldu2019s item number.Fieldu2019s column number.NUMBER/CURRENCY/DATE/0]
The system is able to uniquely identify each field of a document using the fieldu2019s index number and fieldu2019s column number. If you have activated the debug information under View  Debug Information, the system displays the fieldu2019s item number and the fieldu2019s column number in the status bar.
You use the NUMBER parameter if the field concerned contains an amount and a currency key, and you want to extract the amount only.
You use the CURRENCY parameter if the field concerned contains an amount and a currency key, and you want to extract only the currency key.
You use the DATE parameter if the field concerned is a date field and you want to use it for calculations.

ORA-24327 with OCI driver

Hi,
We noticed that when we use the OCI driver for Oracle 8.1.7, we cannot have
an initial connection pool size greater than 249. On the 250th one, there is
a DBMS exception (ORA-24327) and weblogic says that it cannot create the
connection.
If we move to the Thin driver, there is no longer this restriction and we've
tried it with success with more than 550 connections.
Anyone know any limitation about the OCI driver and if there is any
parameter on the OCI driver side or on the DB side to tune so that we can
have more than 249 connections in our pool ?
FI, we have the following configuration (in config.xml) :
<JDBCConnectionPool CapacityIncrement="5"
Name="imJDBCConnectionPool" Targets="imadmin"
DriverName="weblogic.jdbc.oci.Driver" URL="jdbc:weblogic:oracle"
InitialCapacity="270" MaxCapacity="270"
TestTableName="dual" RefreshMinutes="40"
ShrinkingEnabled="false" ShrinkPeriodMinutes="15"
Properties="user=im;password=im;server=im09"/>
and we have the following TNSNAMES.ORA :
IM09.IM =

Hi Vincent,
Just for curiosity sake, what are you doing with 250 connections?
It's not in the Cactus area, is it? :-)
grin ;-)
No, I'm currently working for a customer, doing some lab performance tests.
We wanted to use the OCI driver for the TAF feature of OPS (transparent
application failover) but found that the Thin driver is performing so much
better that we have switched to using it along with the multipool feature of
WebLogic. Hi. Beware of 'TAF'. Note that all cursors will be defunct on failover,
so any JDBC statement or ResultSet in progress at the time of failover will
be lost. (IE: not at all transparent).
Joe
We haven't done any failover test yet so we don't know yet how the
multipool (with a 'load-balancing' strategy) perform upon failover of one
instance. If it's ok we'll keep using the thin driver. If not, we'll switch
back to OCI drivers and try the TAF feature.
Also, I don't think we really need that big number of connections. It seems
we had some other performance issue which the DB which was making us use
lots of connections on the WL side. With the thin driver we're only using
about 39-100 connections maximum with a thread count of 40 (that's because a
given message does up to 3 SQL statements per transaction (and a connection
is only effectively released in the pool after the commit)).
I've introduced Cactus on the project, of course, but only for the unit
tests (I'm also using Mock Objects) ... :-)

Bug in Entity Framework: No rows returned with criteria.

Bug: Oracle fails to return rows with lambda criteria on string field from varchar2 column in view.
Steps to reproduce:
Create view:
CREATE OR REPLACE VIEW "PHILIP_TEST" ("ROWNUMBER", "DRIVER") AS
SELECT
ROWNUMBER,
DECODE(DRIVER,CHR(2),NULL,DRIVER) DRIVER
FROM FLIGHT
WHERE SCHEDULEDDATE = TRUNC(SYSDATE);
Rownumber is unique key (number), Driver is varchar2(7).
Create C# console application in VS2010
Add Entities Model and add view.
Add this code to Main()
var context = new Entities();
// Test code start
var allrows = context.PHILIP_TEST.Where(x => x.DRIVER != null).ToArray();
Console.WriteLine(allrows.Count());
// Select first driver as criteria
var driver = allrows[0].DRIVER;
Console.WriteLine(driver);
// Test code end
// This line fails to return any rows
var result = context.PHILIP_TEST.Where(x => x.DRIVER == driver).ToArray();
Console.WriteLine(result.Count());
Console.ReadLine();
Add some test data to flight.
Run it!
The expression with criteria x.DRIVER == driver should return at least 1 row. It doesnt.
Running the following from SQL Developer returns records: Conclution the view is fine.
SELECT * FROM PHILIP_TEST WHERE DRIVER = 'MJA'
If definition of DRIVER column in view is changed from: "DECODE(DRIVER,CHR(2),NULL,DRIVER) DRIVER" to just "DRIVER", then code returns rows as expected.

are you sure your two select statements can't be combined to one query with outer join?
if the outer join is possible, after creating the query, it will have one group with all the fields/columns you selected.
drag the columns you selected in the personal info, outside the group.
this should enable you to have one query with two groups, a master (personal info) and a detail (monetary calculations).
your first frame will have the master group as source, while for the second the detail. now, the "Value if Null" should work.
if the outer join is not possible,
create one query with only the personal info. in the group, create column formula to get the monetary columns (you may need to create place holders if selecting multiple columns)
drag the columns you selected in the personal info, outside the group.
this should enable you to have one query with two groups, a master (personal info) and a detail (monetary calculations, you CF_ and CP_ columns).
your first frame will have the master group as source, while for the second the detail. now, the "Value if Null" should work in your CF_ and CP_ columns

Retrieve Distinct Values using XQuery

The following query is returning me duplicate rows. How can we retrieve the distinct values? Can we use Distinct somewhere in this query? Please help me.

$demo_audit_type = "U"
return
<result>
<type>U</type>
<id>{$demo_id}</id>
</result>}</Data>' RETURNING CONTENT)

Geoff,
I tried distinct-values in both let and return; however the result isn't distinct. Is the usage correct?
SELECT XMLQuery('<Update>
{for   $a in ora:view("EMP")
       let   $a_empno         := distinct-values($a/ROW/EMPNO/text()),
             $a_ename         := $a/ROW/ENAME/text(),
             $a_job           := $a/ROW/JOB/text(),
             $a_mgr           := $a/ROW/MGR/text(),
             $a_deptno        := distinct-values($a/ROW/DEPTNO/text())
       return
       <op>

Bug: "Paste Special: Value" overwrites data hidden with Table filters

I've noticed the following....
Create a sheet with the values below and enable the "Filter" option on this table.
(I've added the row-numbers on the left, to later show the filter in action)
(1) col1
col2
(2) a 1
(3) a 2
(4) a 3
Using the filter option on the col2 column, unmark value "2".
This is an essential step, since the bug only appears when hiding rows -in between- of other rows.
Hiding 1 or 3 will not have the same result.
You table should now look like this. Notice row (3) is hidden, as it should be:
(1) col1
col2
(2) a 1
(4) a 3
Now type "b" in a random empty cell, select the cell (not the value), and copy it.
Now, and this is an essential step, click down on the "a" value on row (2), keeping your mouse pressed, drag to the "a" value on row (4), so that both cells are selected with one selection box, not two separate boxes.
Within this selection box, right-mouse click, and select "Paste Special -> Values" NOT "Paste Special -> Paste".
Now use the filter to unhide value "2". You table should/will look like this:
(1) col1
col2
(2) b 1
(3) b 2
(4) b 3
This is -not- the expected behavious, when using "Paste Special -> Paste", the result is
as expected:
(1) col1 col2
(2) b 1
(3) a 2
(4) b 3
This issue is also present in Excel 2010, and i've tested this on various computers.

Tested in Excel 2013, it also happens there.

Retrieving time value using getTimestamp

Hi, I like to retrieve date fields from Oracle9i database using getTimestamp. This works fine if the Date field has a date in it, or is null. However , if I try to retrieve a date field which only has a time component , say it is being used to store someones start time for their job (:-((((, then it fails with a format exception.
I can obviously use some other get , but why shouldn't I be able to retrieve a pure time value from a date using getTimestamp (0900 AM).
Is there any other way which would let me retrieve this using getTimestamp. I would like to keep all my date/times get and sets from the database as Timestamps.
Thanks in anticipation , Colin C
Exception was .... java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss.fffffffff; nested exception is:
java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss.fffffffff

Hi Colin,
I just answered this very same question you asked in Oracle's Technet forum. I will explicitly state what I implicitly hinted at in that response.
If you supply details of your platform/environment, plus the full error message and stack trace you are getting, as well as the part of your code that you believe to be causing the problem, I may be able to help you resolve it.
Good Luck,
Avi.

Excel 2013 bug printing when using two printers with same driver

Hi,
Was advise by "Community" to post this one here.
The environment:
Window 7 Sp1 x64
Office 2013 Sp1 32 bit
Windows 2012 Server (current patches).
Two IDENTICAL network connected printers shared from above Windows 2012 server.
As the two printers are the same, they both use the same printer driver.
Printer A is set to Greyscale. This is the default printer.
Printer B is set to Full Colour.
Open Excel and start a blank worksheet.
Choose Print - this shows the default printer (Printer A) - then Printer Properties - this verifies that the Default Printer is set to Greyscale as expected.
Change printer within Excel to Printer B - then printer properties again - this shows us that printing is STILL in Greyscale ignoring the Printer B settings. Printing will indeed produce a greyscale print on Printer B.
The reverse is also true - if we set Printer B (Color) as the Default, then choose Printer A (Greyscale) inside Excel, it will then show (and print) in Full Color - ignoring the printer A setting of greyscale.
This ONLY occurs when connecting to Shared Printers on a Windows host (Server 2012 in this case).
Direct IP printing from Win 7 to the printer works as expected (printer settings honoured).
Non-Windows server based printer sharing works as expected (printer settings honoured).
This ONLY occurs in Excel. Other programs including other Office components do not exhibit this bizarre behaviour.
This ONLY occurs where the same driver is used by both printers.
In effect, Excel is transposing the Default printer's settings onto whatever printer is chosen if it uses the same driver.
Installing Office 2013 Service Pack 1 made no difference.
This appears to be a long running issue (search result show Excel 2007,2010* and Windows 2008R2 server references).
*Confirmed same behaviour with Windows XP and Excel 2010.
This appears to affect multiple brands of printer (Xerox, Konica Minolta). Confirmed with 3 different generation Konica Minolta (Postscript) copiers and Dell multifunction (with PCL drivers).
Does anyone have a solution for this ?
Is there a setting hidden in Excel that should be changed ?
Is there a server setting to "isolate" the two printers from each other ?
Regards
Ian

KR,
Thanks for the reply but note I said "The reverse is also true - if we set Printer B (Color) as the Default, then choose Printer A (Greyscale) inside Excel, it will then show (and print) in Full Color - ignoring the printer A setting of greyscale."
Also, it is the printer properties that are being set. I believe the setting you refer to is per worksheet ?
Cheers
Ian

Installing XP using boot camp with partitiion drive?

I recently re-installed Leopard on my mac, and i decided to partition the drive.
Then, when I went to install XP using boot camp it said that it only works with 1 partition!
Is there any way round this without re-partitioning my drive?
I also have an ext drive now so maybe I could install it there, but that would be slower.

I just tried to run the hardware diagnostic test, half way through, the screen started to flicker so much, I had to abort the test. Please help!

Using XML DB with Oracle Drive as Webdav client

Hi all -
I'm looking into using XML DB (10g) to store files so we can query their content via SQL/XPATH and then access/edit them via Webdav.
Windows Vista makes this easy, since it can map a drive to a Webdav URL. Mac OSX can do a similar thing.
Windows XP however can't do the drive mapping for WebDav on a port other than port 80, which is our setup.
So I tried out Oracle Drive, which I stumbled across on some site somewhere, and it worked. But it was an old version, so I downloaded the "official" version from Oracle, which is v10.2.0.0.22. This version refuses to connect to XML DB no matter what I do. I've fiddled with authentication, proxies, and so on (there are several posts elsewhere with hints on this) but so far no joy.
Has anyone had any experience making the latest version of Oracle Drive talk to XML DB?
Many Thanks

Thanks for replying.
Yes, we may decide to move XML DB to port 80, but there are other services running on our server and such a move would be a significant hassle.
As for Windows XP, it is not possible to do this: net use * http://server:8080/public
This works on Vista, but it only works on XP if you use port 80.
Note that XP has TWO built in Webdav clients: Web Folders (= Network Places) which is a feature in Explorer, and the Webdav Mini-Director which works at the file-system level. I don't think Web Folders can work for us since we need to be able to create a real filepath to give to our editor application. Maybe I'm wrong on that, but I can't figure it out.
Oracle Drive seems to be a great solution, but I can't make the most recent version work (the old version worked but was buggy).

Major problems using DV cam with external drive connected. HELP

I am running Final Cut Pro 5.0.4 and Quicktime Pro 7.0.4 and I want to use one of my external Firewire drives as my scratch disk, and when I connect my Canon GL2 FCP either crashes if it is open, or hangs when trying tro start uo if external hard drives are connected. As I need to use an external to capture to I really need to resolve this A.S.A.P.
Thanks in advance for your reading and replying to my post,
Sebastian

firewire external hd is a perfectly acceptable medium for capturing footage. it works pretty flawlessly and has little issues or problems
This type of blanket statement really can't be supported in my view.
There are issues with single bus firewire captures.
And many cams, including Canons, don't play well with firewire hard drives on the same bus.
Glad it works for you, but that's doesn't mean it works for everyone.

How do I use migration assistance with hard drive reader for dead macbook

Hi,
My old mac laptop died without warning.
I took it to the apple store and they suggested getting a hard drive reader and using that to transfer
across my files.
I've connected it up and have requested the migration assistant to transfer the files. Last night it
said it would 27 hours to transfer and now this morning it is saying 72 hours. This seems to
be a very long time - is it correct? Can I make it go faster or is there another way?
I've got a bit of music on there but nothing excessive. I do have about 15,000 photos though.
I'm not very techy so any assistance would be very helpful
Thanks
Sarah

Hi, that's far to long, unless maybe it's USB1.1 speed.
If USB2 or Firewire, I'd start ober & try Disk utility>Repair Disk on the external drive.

Can you use time machine with 2 drives

I'd like to make two Time Machine backups - one per external drive - so that I can keep one in a different location. Is that possible? When I switch drives will each backup know where to pickup?
Thanks.

Yes, although that's not the best way to keep secondary backups.
See Time Machine - Frequently Asked Question #27 for details.
