How can I guarantee the consistency of tracsaction

Hi,
We have a product called SMS(Subscribe Management System). It is a CCB(Customer Care Billing) System used in DVB domain, and contains two server: billing server and customer server. Billing server is written using C++, Customer server is written using java. We uses corba for communications between Billing server and Customer server. Billing server uses omniORB-4.0.6(Opensource C++ ORB), Customer Server uses weblogic server 9.0, and uses weblogic ORB to invork corba service provided by Billing server in sessionstateless bean.
We have succeeded in invorking corba service in slsb, and now my challenge is the tracsaction in two server must be consistent, so I think it should be use distributed tracsaction and two-phase commit, but omniORB-4.0.6 doesn't provide any tracsaction support.
Could someone give me some advice for the question below
1ã€Must I use distributed tracsaction and two-phase commit?
2ã€How can I guarantee the consistency of tracsaction? I think I can define corba service throws exception, and in slsb, I can catch the exception and the CMT mechanism could guarantee the consistency of tracsaction; but if exception occurs in slsb, how can I rollback the tracsaction in billing server?
Any insight into the problem is appreciated.
Thanks
Haocheng Yuan

Switching to FIOS, want the new high-capacity DVR. How can I guarantee getting one?

After 12 years I have to say goodbye to Dish because my old oaks are getting too tall and too wide and I don't have a clean line of sight...so I'm switching to FiOS. I've gotten used to the best DVR in the industry, and I understand that there are new high capacity DVRs for FiOS that rival the Dish DVR's capacity. How can I guarantee that when I order FiOS I'll get one?

You can't . Its whatever is put on the truck that morning. HOWEVER, you can do what I did and refuse the install. My installer was nice enough to go back to the office and get one for me. It is outgrageous to offer the older smaller equipment to new customers.

How can I set the different boolean text in the button array?

I created the OK boolean button array. How can I change the boolean text of each button to be different at run-time? I changed one, but the others are changed also.

> Thank you for your help

Select the control using the positioning tool and choose
Customize... from the Edit menu or choose it by popping up
on/right clicking on the control and selecting Advanced>>
Customize...
This will open the control up in a new window -- the control
editor window. This window allows for lots of additional
control modifications and allows for them to be saved into
typedefs to promote reuse and make things more consistent.
Once in the control editor, popup on the button and select
the menu item near the bottom Multiple Text Strings.
Close the editor window and the first dialog will ask if
you would like to save the change
d file. Choose No, and a
second dialog will ask if you would like to Replace the
Original Control. Choose Yes.
At this point the Button will support multiple text labels.
To edit the True string, make the Boolean True and use the
Labeling tool to edit the string that is visible. To edit
the False string, make the Boolean False and use the labeling
tool to edit that string too.

How can I change the name of item in TableViewController iOS

How can I change the name of item in TableViewController? I want to be able to change the title of an item if I added one. Code:
// ViewController.m
// Movie List
// Created by Damian on 20/02/15.
// Copyright (c) 2015 Tika Software. All rights reserved.
#import "ViewController.h"
@interface ViewController ()
These outlets to the buttons use a `strong` reference instead of `weak` because we want
to keep the buttons around even if they're not inside a view.

How Can i retain the Shared Variable Values after PC rebooting

Hi all,
I am facing a paculiar problem with Shared Variables. I have an application in which shared variables are used for data communication.
One of the application requirement is to retain the variable values eventhough PC is rebooted or started after crashing.
As per the my understanding, the variable values will retain eventhough the PC is rebooted. But here i can observe a paculiar problem like some library variables are retaing the values while some others not. I enabled logging for all the variables.
I tried many ways. like logging enabled, logging disabled, changing variable names, changing process names etc... But i am not getting a consistent behaviour.
I hope some you can help me in solving this issue.. "How Can i retain the Shared Variable Values after PC rebooting"
Thanks and Regards,
Mir

Hi Blackperl,
Thanks for the post and I hope your well.
What do you mean by not getting consistent behaviour.. this will all depend on excatly when the crash happens i.e. before the write or after.
Surely a better method would be to log the data to a file during the reboot...
I beleived the value read back
will be the default value for the shared variable's data type.
The LabVIEW DSC 8.0 module adds more functionality to the shared variable, including initial values and alarms.
If you enable an initial value on a shared variable, when the variable
engine comes back on-line it will default to this value. Setting a bad
status alarm for the shared variable is also a good way of handling
this type of event. Additionally, if you are using a LabVIEW Real-Time
target such as Compact RIO or Compact FieldPoint, it is appropriate to
consider hosting the shared variable engine on the real-time target.
These devices have watch-dog capabilities and are typically the
hardware controlling the critical pieces of an application. Most
Windows or PC-based targets do not have these fail-safes.
I guess, if you could explain to me again that would be great. From my point of view, if I have a cRIO and a Windows PC. If the windows PC crashes, the cRIO will still update its shared variables. Then once the PC has started up its own shared variable engine, and the bindings are loaded, it will once again continue to update its copies of the variables.
Please let me know what you think,
Kind Regards,
James.

How can i transfer the system variable value through DTW in SBO

Hi,
I want to transfer the system variable("Excisable" in the Item master data in the SBO 'India' database) value through the template by the DTW.
But i don't have any template consisting of this system variable.
So please suggest me that how can i transfer the value of this system variable(Excisable) and by which template.Please tell me any constraint if it is on the value of this variable.
I will be very thankful to you.
Thanks & Regard,

How can i locate the properties files within a ejb container?

when i develop servlet+javabean structure application,in order to imploement decoupling,i
would like to write the config information in the properties files(key-value pair),in
servlet,i use "getResourceAsStream(String relativePath)" method to retrieve the
configuration information from the properties files(i even write the SQL clause
in the files),it alwsys works well.
now,i want to implement such function within the ejb container,that is to read
a properties file from session bean,but i don't know how can i locate the file
within the ejb container by using relative path,i wonder if there is the same
method within ejb container as "getResourceAsStream(.......)" method within servlet
container?
thanks for any helps!
the code snippet is appreciated!

In general, you should look at using environment entries (variables) in the
deployment descriptors (both the war and EJB jar rather than properties
files for configuring J2EE applications. The reasons for this are many:
1. This is the official way to do it according to the spec. Properties
files are the J2SE way of doing things
2. As you note, that it's not obvious how you would (legally) read a
properties file inside an EJB.
3. It's consistent between the web and EJB part of your code
4. the weblogic console and tools have good capabilities to edit these
fields.

How can we take the incremental export using the datapump at schema level.

Hi,
How can we take the incremental export using the datapump at schema level. Example, today i had taken the full export of one schema.
After 7 days from now , how can i take the export of change data , from the data of my full export.
using the export datapump parameter - FLASHBACK_TIME ,can we mention the date range. Example sysdate - (sysdate -7)
Please advice
thanks
Naveen.

Think of the Data Pump Export/Import tools as taking a "picture" or "snapshot."
When you use these utilities it exports the data as it appears (by default) while it's doing the export operation. There is no way to export a delta in comparison to a previous export.
The FLASHBACK_TIME parameter allows you to get a consistent export as of a particular point in time.
I recommend you go to http://tahiti.oracle.com. Click on your version and go to the Utilities Guide. This is where all the information on Data Pump is located and should answer a lot of your questions.

Uniqueness conflict avoidence,guarantee the consistency of data?

I lil'(........okay ,alot) confused about when is exactly we use the conflict avoidence (e.g. generating sequence number)or resolution???If we have alot, say it's millions row of data, is it wise for us to implement the conflict avoidence, since the generation of sequence number never guarantee the consistency of data.Just 4 example if i insert a new record for a students table, and I used the sequence number as the PK, it's never guarantee that a row with some information on it will not have redundant copies.....Confused...Could anyone have any solution for uniqueness conflict resolution/avoidence instead of generating the sequence number???Thanx lot!!!

I'm not completely sure I follow your question...
If you are asking how to ensure that a particular primary key is not reused in multiple nodes in a replicated environment, the easiest answer is to set up slightly different sequences on the different nodes. That is, when you have N nodes
Node 1
CREATE SEQUENCE seq_name START WITH 1 INCREMENT BY <<n>>;
Node 2
CREATE SEQUENCE seq_name START WITH 2 INCREMENT BY <<n>>;
Node N
CREATE SEQUENCE seq_name START WITH <<n>> INCREMENT BY <<n>>

How can i guarantee that comma (8'hbc) will be aligned to first byte of received data?

i'm now using the spartan6 gtp to transmit 32 data through the fiber(with 8b/10b encoding enable),when i send the data which includes the comma (32'h090909bc),how can i guarantee that comma (8'hbc) will be aligned to first byte of received data .and i just can guarantee that comma (8'hbc) will be aligned to even byte of received data (attribute ALIGN_COMMA_WORD is set to be 2).

Hi,
Please avoid posting multiple post. I have answered your query here - http://forums.xilinx.com/t5/Spartan-Family-FPGAs/how-can-i-guarantee-that-comma-8-hbc-will-be-aligned-to-first/m-p/644938/highlight/false#M32601

Please help me, How can i minimize the deadlock issue for this event

Indexing improvements might greatly improve query performance and reduce likelihood of deadlock, but they are no guarantee to remove deadlocks.
An additional strategy you might try is to serialise the queries. I am guessing that the SELECT and DELETE start at similar times getting IS and IX table locks respectively. Then the DELETE is escalating to a table X lock, for which it must wait for the
IS lock to go. The SELECT query continues until it needs a record/page that is X locked by the DELETE statement. That would be a deadlock. For the DELETE, you might get a full table lock at the beginning of the query. ie try changing the DELETE to the following
BEGIN TRANSACTION
SELECT TOP 0 * FROM WMDLXK.CDM_LOCATION_QUANTITY WITH (TABLOCKX)
DELETE FROM WMDLXK.CDM_LOCATION_QUANTITY WHERE EDI_BATCH_ID = @P0
COMMIT TRANSACTION
The SELECT in the query above will wait until it can get a full table X lock. No deadlock as it will wait for executing select queries to complete. Then the DELETE statement can execute within the full table X lock, so no deadlock there. At the COMMIT, the
full table X lock is released and waiting SELECT queries can continue.
Note: The SELECT queries will be slowed up (waiting for shared lock) while the DELETE executes. Are you OK with that? Actually, it is slightly worse, as a SELECT query might have to wait while the DELETE waits for its X lock, then wait while the DELETE executes.
Hope that helps,
Richard

How can I findout the coulm value contains 0 through 9 for the table

could u plz suggest me how can I findout the coulm value contains <> 0 through 9 for the table...

Well I am going to give it a shot, because I believe I am looking for the same thing.
I have a value that is of type varchar2. How can I determine if it has special characters or alpha characters in it? In other words, I only want the value to consist of numbers. (Initially it had been thought that Letters would be used as well, but now they just want numbers and the datatype of the column cannot be altered since there is data in it.)
I have gotten this far, but I do not know what else I can use besides '[:alpha:]'? I cannot seem to find this documented anywhere...I can find the regexp package reference, but not the character classes...
select regexp_instr('1a23456', '[[:alpha:]]',1,1,1, 'i') x
from dual
This works fine = returns 3, so I know there is an alpha character.
select regexp_instr('1$23456', '[[:alpha:]]',1,1,1, 'i') x
from dual
This returns 0 - what do I need to change so that it detects the '$' and returns 3?
Thanks!!
