Documentation bug?
Is the documentation right when it states that the getKeyPartition mathod must be in the range [0..N), where N is the value returned from PartitionedService.getPartitionCount()? I would have guessed it should be in the range [0 .. N - 1]?
/Magnus
Hi Magnus,
With the set notation on the page linked by Rob, [0..N) and [0..N-1] are equivalent (for integers).
For example, if N=3 (partitions) then:
* [0..N) represents the set {0, 1, 2}
* [0..N-1] also represents the set {0, 1, 2}
Using your example, the code should be "xxx % PartitionedService.getPartitionCount()" (or an appropriate equivalent).
Of course, that same page also points out that ")" is rarely used with integer intervals. And I agree that it would be more clear to use the closed interval notation [0..N-1]. I'll enter an enhancement request for the javadoc.

Documentation bug- -Djava.security.policy==weblogic.policy?
All,
According to the documentation, an example of invoking weblogic server
from the command line for JDK1.2 is as follows:
JDK 1.2 (Java 2) example
$ java -ms64m -mx64m -classpath c:/weblogic/classes/boot
-Dweblogic.class.path=c:/weblogic/classes;
c:/weblogic/license;c:/weblogic/lib/weblogicaux.jar;
c:/weblogic/myserver/serverclasses
-Djava.security.manager
-Djava.security.policy==c:/weblogic/weblogic.policy
weblogic.Server
Is the property
-Djava.security.policy==C:/weblogic/weblogic.policy
correct in that there are 2 equals signs? Should this be rather:
-Djava.security.policy=C:/weblogic/weblogic.policy?
It seems as if either works, I just wanted to clarify, as I've noticed
our startup scripts use the former and not the latter.
Thanks,
BenHi Ben,
the doc is correct, there is a semantic difference between '==' and '=',
check
http://java.sun.com/j2se/1.3/docs/guide/security/spec/security-spec.doc3

Apex 4 JavaScript API documentation bug
Hi,
JavaScript API documentation have exactly same description for functions
$f_Hide_On_Value_Item
$f_Show_On_Value_Item
>
Checks an page item's (pThis) value against a value (pValue). If it matches, a DOM node (pThat) is set to hidden. If it does not match, then the DOM node (pThat) is set to visible.
>
And also functions have same description
$f_Hide_On_Value_Item_Row
$f_Show_On_Value_Item_Row
>
Checks the value (pValue) of an item (pThis). If it matches, this function hides the table row that holds (pThat). If it does not match, then the table row is shown.
>
I think that is not correct
http://download.oracle.com/docs/cd/E17556_01/doc/apirefs.40/e15519/javascript_api.htm#CHDHIAJB
Somehow I recall there has been post about this, but I can not find it.

Documentation bug - "creating an about box" in wrong topic
I think I found a small error in the documentation for LabVIEW 2012. Under the Index tab, find 3D Surface. For some reason, the topic "Creating an About Dialog Box for a Stand-Alone Application" is listed under it, even though it has nothing to do with the 3D Surface plot. See attached image.
Solved!
Go to Solution.Hi nathand,
Thanks for the freedback. I will make sure this bug gets reported to the correct poeple and fixed.

Domain.Date / Documentation Bug??
Hi,
The documentation for addMonths() in domain.Date states that the method overrides addMonths() in sql.Date to return a domain.Date.
It doesn't. It still returns a sql.Date.
Am i wrong??
Enjoy!!Hi
The domain.Date:
addMonths
public DATE addMonths(int months)Adds months to a date. Overrides the oracle.sql.DATE method of the same name to return a Date Domain object.
Returns:
new Date object initialized to the Date value added to months. Months can be negative to perform month subtraction.
See Also:
"oracle.sql.DATE"
package mypackage1;
import oracle.jbo.domain.Date;
public class Class1
public Class1()
public static void main(String[] args)
Date date1 = null;
Date date2 = new Date();
date1 = date2.addMonths(1);
Error(16,28): incompatible types; found: oracle.sql.DATE, required: oracle.jbo.domain.Date
What am i doing wrong?? -
Order Item Specification Editor Property References Tab - Documentation Bug
Hi,
I am trying to create a cartridge with Order Transformation Manager entities. However I'm stuck with Property References tab of order item specification in 7.2.4 DS. I checked the documentation but its not completed it seems.
http://docs.oracle.com/cd/E49311_01/doc.724/e41610/dscom_oi_edt_propref.htm#DSCOM142
Check the above URL under "Dynamic Parameter Property"I notified the appropriate writer, who replied that the Dynamic Parameter Property description should read: "Select the order item property in which dynamic parameters for the order item should be stored."
The fix will be included in the help for the next major release. -

After Effects CC documentation bug and question
When you visit the page for AE CC to see if your Mac is eligible to run After Effects you go to:
https://creative.adobe.com/products/aftereffects
You are told
Optional: Graphics card from list below with at least 1GB VRAM and CUDA 5.0 for GPU acceleration of ray-traced 3D renderer
But there is no list below. It just switches to talking about the PC.
Can someone tell me which Graphics cards for the Mac are best to utilize the 3D ray-tracer in AE?
Thanks!The effect on render time depends entirely on the project. Temporal effects require CPU, particle effects require Ram, source footage that uses a codec that is hard to decompress line all mpeg formats load up the CPU, rendering large frame sizes may bog down the whole render if the pipeline to the destination disk is plugged up or the disk is slow. Personally I would say that once the minimum ram for your largest average project size is met, for my that is 4GB per core, CPU speed is the first consideration, then, GPU last.
Right now the only major consideration for me when considering a GPU purchase is compatibility with the Mercury playback engine used by Premiere Pro and it's inclusion in the approved for my 3D apps list.
My careful assessment of hardware requirements for the purchase of my new Mac Pro led me to the 8 core with 32GB and the D700 GPU because I could not find enough value in the nearly 30% price difference for the 12 core 64GB setup considering my projected work load for the next 2 years. If I end up doing larger resolution projects or Adobe significantly changes the way After Effects handles MP rendering I can always trade in for more capable system. Macs retain enough of their value that this was the best business decision. I'll use the savings for more storage and a couple of new plug-ins.
I hope this helps you make an intelligent business decision on your hardware purchase. -
Documentation bug/typo in Apex 4 workspace export
To someone on the Apex dev team:
I just did a workspace export from Apex 4, and noted the following remark near the top of the generated file:
This script can be run in sqlplus as the owner of the Oracle Apex owner.I can't make any sense of that statement. I know I can run the script as SYS, and perhaps as a used with the APEX_ADMINISTRATOR_ROLE, but I'd like the generated text in the script to be corrected/clarified.
Thanks!

Is this a bug in the intensity map cursor?
I'm using LabVIEW 7.1 on Windows 2000. When I pan an intensity graph, it jumps around. If there is a curosr over the map, the cursor does not jump with the map and can lead to the cursor reading from the wrong pixel. I've attached a vi that demonstrates my problem. Is this a known bug?
Attachments:
buggy-cursor.vi 707 KBExcellent work on the example VI! This is not a documented bug to date, but I was able to reproduce the unexpected behavior you were talking about. I will pass your example on to our R&D department to investigate and to take corrective action if necessary. Thank you so much for your feedback and hard work.

Data Guard Logical Standby Skip Handler bug
Does anyone know of a documented bug concerning the skip handler not skipping a grant on a view in a schema with a SCHEMA_DDL skip handler defined?
Here is my test case.
On Primary:
Create table scott.junk (x number) tablespace users; (created successfully on logical standby)
On logical standby:
exec dbms_logstdby.skip('SCHEMA_DDL','SCOTT','%'null,true,'\'); (created skip handler on all SCOTT objects)
On Primary:
grant select on scott.junk to public; (successfully skipped due to missing object)
On Primary:
create view scott.v_junk as select * from scott.junk; (successfully skipped on logical standby)
On Primary:
grant select on scott.v_junk to public; (received 'ora-00942 table or view does not exist' on logical standby and SQL Apply stopped).
I'm running version 10.2.0.4 but have not applied the recommended patch bundle for logcal standby #7937113.8.
If anyone knows whether this has been documented or not, please let me know. If not, I will submit an SR to get this documented.
Thanks,
Michael Anderson
OCP - Bank of the WestWhen I look at the syntax for the package
http://www.morganslibrary.org/reference/dbms_logstdby.html
what I see is:
dbms_logstdby.skip(
stmt IN VARCHAR2,
schema_name IN VARCHAR2 DEFAULT NULL,
object_name IN VARCHAR2 DEFAULT NULL,
proc_name IN VARCHAR2 DEFAULT NULL,
use_like IN BOOLEAN DEFAULT TRUE,
esc IN CHAR1 DEFAULT NULL);So looking at your code:
exec dbms_logstdby.skip('SCHEMA_DDL','SCOTT','%'null,true,'\'); (created skip handler on all SCOTT objects)
'SCHEMA_DDL' is your statement.
'SCOTT' is your schema name.
'%' indicates all objects
and ... shouldn't there be a comma before the NULL?
In the future don't provide values where the default's will suffice. It makes thing's far simpler.
