Correct way to cleanup lccs state for Connect/Disconnect functionality

I am trying to implement connect/disconnect functionality but I got some errors - when user connects to another room after disconnect different objects(for example AudioPublisher) may end up in incorrect state. Currently I perform following sequence of actions on disconnect: call stop method on AudioPublisher, call close method on AudioPublisher, and then call close method on ConnectionSession. When I reconnect again AudioPublisher object in wrong states and throws different exceptions("Stream not found", "Stream already exists"). Can you recommend some approach to avoid these errors?
Best Regards, Aleksey

Hi Aleksey,
Seems like using multiple connectsession (connecting to different rooms) is messing your app. We handle most of the clean up in the close & stop methods for AudioPublisher. If you are still facing issues can you share your code.
Thanks

APP-ALR-04106: Please correct the user-defined SQL statement for this alert

Hi All,
I have created an alert for engineering module in R12. It got tested and was working fine. when the user testing it, while trigger the alert getting the error, "APP-ALR-04106: Please correct the user-defined SQL statement for this alert".
when verified the alert, it got verified and ran also. It parsed the query successfully and when run it fetched few records.
Need help in resolving the issue.
Thanks in advance.

Hi Sri;
I have already gone through the Note: 948037.1. But this note is related to 11i. The solution provided in the Note is for 11i.
I am facing this issue in R12. Is this patch applicable to R12?I belive its not. But u can check Solution part 4 for your instance, at least it can give you idea. The other note in metalink related bug and all for R11 too.
I belive its better way to rise Sr while waiting other forum user response to that thread

Wondering if this was the correct way to patch my kernel for CFLAGS?

Hello. I use to build the zen-sources kernel but stopped many months ago. I didn't really need all of those patches but I did miss the Custom CFLAGS/MAKEFLAGS option that the zen kernel had. I also missed the 432HZ Timer frequency setting available in the zen patch.
So I researched a bit and grabbed these parts from the zen patch to add to the Arch kernel:

Well the code was added to my make menuconfig kernel settings, and is in the .config of my newly compiled kernel..... I'm just wondering if I did this correctly. (I'm pretty sure that I did a crappy job of patching since I just grabbed the pieces of the zen patch that I thought were the correct one)..... This is the message from the patch:
patching file Makefile
patching file init/Kconfig
patch unexpectedly ends in middle of line
Hunk #1 succeeded at 734 with fuzz 2.
patching file kernel/Kconfig.hz
patch unexpectedly ends in middle of line
Hunk #4 succeeded at 90 with fuzz 1.
So if someone can tell me a better way to patch the kernel26 for custom CFLAGS and 432HZ Timer frequency (for dual core) I would appreciate it. Thanks.

I'm still trying to find out if I needed to patch any other parts of the kernel source when I added CFLAGS to the kernel modules? I also would like to know if I did the Timing part correctly (so I could use the 432HZ setting for a dual core).
..... so far this kernel has worked ok for the last 4 days. Does anybody know how I can benchmark it and compare it to other kernels that I have built with different settings?
Any info is appreciated.

What is the correct way to set up artwork for a Billboard?

I need to set up photoshop artwork (which consists of about 5 layers) for a 6m x 3m billboard. I set up my whole billboard in Illustrator (at 3m x 1,5m - half of actual size) and placed the psd image in. I set up my photoshop artwork at a third of actual size (3m x 1m at 300dpi). However, this made my file VERY slow to work with (result was about 700mb!!!!). Someone suggested that I downscale the image to 500mm wide and choose resample image > Bicubic Sharper (best for reduction). This scaled my psd file to about 32mb, which worked much faster. Then I saved the psd file as a Tiff with LZW compression without layers and placed into my illustrator file. However, when I export for print as PDFX1a- 2001 my file size was only 17mb!!!! Did I do the whole process correctly?! Will the print quality still be fine for such a big billboard? Is there a better / standard way to set up photoshop graphics for a billboard?

You can use this test to check ppi resolution.
On your desktop printer print a few tiles from the image in real size at different ppi resolutions like 10, 20, 30, 40. Find a wall where you can mark 6 meters, and tape the tiles on it. Now step back to whichever is longer distance - from where you can see comfortably the whole size of the eventual billboard without turning your head or to the distance that will be possible to see the actual mounted billboard, . Choose the ppi resolution on which you can't see pixelation on the printed test tiles.

Correct way to Copy SD Card for FCP X

I have a series of SD cards that have AVCHD footage that I'll eventually ingest into FCP X. What I'd like to do is make a copy of the footage onto one of my hard drives and use that copy for Log and Transfer. I know I need make sure the file structure is unmodified, so what is the best way of doing this to make sure Log and Transfer goes properly in FCP X?

Correct way to compress 16X9 file for the web

Hello: Shot an HDV project. After importing converted files to DVCProHD. 1280X1080 16X9. Edited 5 min. piece. Exported QT with current settings. Need to upload to You Tube. Please tell me...what's the best choice in Compressor? I tried H.264 Streaming 800kbps and the file now looks 4X3. Please help. THANKS!

sdl wrote:
I tried H.264 Streaming 800kbps and the file now looks 4X3.
Because of the non-square pixel format you're mastering in (DVCProHD) you have to force the frame size to 1280x720. And for an HD file, you can up the bit rate to about 2000 kbps for YouTube. (I believe 800 kbps is recommended for the 16:9 High Quality file)
Also, be sure to turn on Frame Controls (in Compressor), as it'll help maintain sharpness that will otherwise be lost when going to 1280x720. Though that'll up the encode time significantly...

SQL query statement for stored procedure / function listing ...

Hi everyone,
Is there a SQL query to list all the stored procedures and functions of an user in an Oracle 8 database?
I have this idea:
select * from USER_SOURCE where TYPE = 'PROCEDURE' or TYPE = 'FUNCTION'
but I am not too sure whether this is correct.
Thanks in advance,
Eric

Yeah
I agree with you Garcia , my above posting was a correction to the query mentioned in the question only.
you are correct
If you only want the name of the object,
SELECT Object_Name from User_Objects where object_type in ( 'PROCEDURE' ,'FUNCTION');
is much faster than Selecting (distinct) from User_Source.

Stats for Web reports

Then I did load data from RSDDSTAT table into 0BWTC_C02 cube.Now no.of navigation isok but overall time and meantime are displaying as '0'.
What is the correct solution to record bw stats for web based queries?

Hi
My problem is not the performance problem.
When query ran on portal then BW stats not showing the details of meantime ,overall meantime,time olap processor etc.
When I run the stats query '0BWTC_C10_Q010' - Utilising OLAP, It's showing only number of navigations and it's showing remaining all the fields '0'.
How can I resolve this problem.

Attn - The correct way to connect to the repository

From iFS Product Management.
Many people appear to be having trouble connecting to the repository and are using the wrong API calls to do. The recommended API calls changed between beta and production. For the production release here is the correct way to connect:
1. Four pieces of information are need to connect to the repository
1. The iFS User Name
2. The iFS User's password
3. The properties file to be used
4. The database password of the user who owns the iFS Schema
This is different from the beta where the database password was hardcoded into the properties file.
Note that any TNSNAMES information is still containing in the databaseURL entry in the properties file.
package ifs.demo.samples;
import oracle.ifs.beans.*;
import oracle.ifs.common.*;
import java.util.Locale;

CleartextCredential me = new CleartextCredential("gking","ifs");

connect.setLocale(Locale.getDefault());
connect.setServiceName("IfsDefault");
connect.setServicePassword("manager");
return service.connect(me,connect);
public static void main(String[] args)
try {
LibrarySession ifs = testConnection();
ifs.disconnect();
} catch (IfsException e) {
IfsException.setVerboseMessage(true);
e.printStackTrace();
Note that in this example "gking" is the iFS user name, "ifs" is the gking user's ifs password. "manager" is the password of the database user who owns the iFS Schema.
"IfsDefault" is the server properties file that describes the ifs connection. This file is in called "IfsDefault.properties" and is located in the package oracle.ifs.server.properties". This means that the folder that contains the 'oracle' folder that is the root of this package must be referenced in the class path when running this example.
Note, if you use the older, 3 argument form of the connect you will get an unable to connect exception as the iFS will not have the Schema Password.

What is the "correct" way to point iTunes to an NAS disk for my music library

I have a 3.2ghz Core i5 Mac running OSX 10.9.2, iTunes 11.3.
My music library is over 600mb, taking up a very large portion of my hard drive. I have moved my music library to NAS in order to free up space. The "keep library organized" box is checked. Every time the computer loses connection with the NAS, it moves the location of the iTunes library back to the default.
There are several suggestions or "answers" in the communities, but I have not been able to get any of them to work. They all seem like workarounds. Is there a correct way to do this?
Thank you for the help.

Best is to keep the entire library on the NAS unless you have some pressing reason for not doing so. turingtest2 article: Make a split library portable - https://discussions.apple.com/docs/DOC-7392
If the NAS is disconnecting while iTunes is open that is something not built into the programming of iTunes and is a fundeamental problem of using a NAS with iTunes. Actually best is not to use a NAS. iTunes and NAS do not always play nicely together and a good number of problem posts on this forum with unrepairable broken links are from users of NAS. I know NAS owners do not like to hear this but a simple external drive is likely as far as iTunes can handle reliably. Some have gotten NAS to work but there isn't a magic solution.

Standard way of mutual exclusion control for rfc connection

Dear expert,
I want to know the standard way of mutual exclusion control
for rfc connection.
I am going to create JAVA screens for ERP ABAP objects.
As for SAP GUI screen, pessimistic locking is used when editing objects.
On the other hand, pessimistic locking is defficult for JAVA screens,
since most of lock objects on ERP are not available for RFC.
Besides, I'm afrraid if locks are correctly deleted
when something bad happens on screen.(i.e. Users close browsers.)
Do you have any recommendations?
Regards,
Fukuhara Yohei

Hello, we raised an OSS note.
They answered it was not possible to lock tasks.
Task completion is like a race, the first it completes it wins.

Correct way of using LayeredPane for animation

Hi,
before I post my questions some background info (it has become quite a long story sorry for that, you can skip to the bottom if you want):
i'm not an expert java programmer so I appologize for any stupid questions or remarks.
Currently i'm implementing a road traffic simulation. Cars drive over roads, intersections etc. To make the movements/animation look smooth i've used doublebuffering or page flipping (I'm not sure while I used the getBufferStrategy() from a JFrame: strategy = frame.getBufferStrategy(); )
To add my own JButtons created from .png file I've switched off the RepaintManager by creating a NullRepaintManager. The simulation thread is responsible for calling the repaint function, which is done every few milliseconds after the positions of the cars are updated. These buttons are added to the ContentPane of the frame which is made non-opaque to make the roadnetwork and cars visible (*i don't understand this)
Btw I've 'borrowed' these ideas from 'developing games in java ' from Brackeen: http://www.brackeen.com/javagamebook/
The roadnetwork and cars are drawn on the a Graphics2D by calling: (Graphics2D)strategy.getDrawGraphics(); first I draw an image of the roadnetwork to clear the old vehicle positions and then the new positions of the cars are drawn. after that the screen/frame is updated: strategy.show();
This all works fine.
The problems start when I want to have a popup JPanel to appear on the screen after I clicked somewhere on the roadnetwork. According to Brackeen this can be done by initializing a JPanel and add it to the LayeredPane of the JFrame and make it visible when needed. This does not work while the JPanel never pop's up and I don't understand why not, because the demo from brackeen works fine. When I add this JPanel to the contentPane it does popup but the buttons are shifted to the right which is not what i want.
Also I want to add a JMenuBar to the frame, i thought I could simply used: frame.tsetJMenuBar(menuBar);
however the menubar shows up next to my custom JButtons....
====>My Questions:
What is the correct way to draw smooth animations inJava without slowing down the whole program when quite a large area has to be draw... this seems to happen e.g. in the Java demos: ..\jfc\Java2D
How can I popup JPanels or internalFrames ontop of the animation?? probably by using the LayeredPane?
I also want to add a JMenuBar in the normal position.
Sorry for the long text and questions... but I'm struggling for almost two month with this now (using an increadible number of java books) and haven't solved it yet.
Any suggestions are welcome Thanks in advance!!

It gets the first address from the pxelinux.0, another one is usually handed down after it boots, but sometimes it reuses it again.
Usually what happens on a diskless system is it tries to use the dhcpcd lease from the last diskless workstation (or possibly reuses the same one it gets from pxelinux.0). But it has enough logic built into that it looks for another unique address for the next diskless workstation.
Do you have your pxeclient.cfg/default appended options set correctly to be ip=::::::dhcp?
Of course from the diskless wiki:
