Data access

I have a fileLoader class that process multiple files and store data in a Vector of Vector structure(data matrix), then I need to access these data in my other classes to process them. Should I use static modifier for the Vector of Vector in order for other classes to access it? What's the good and quick way to access these data ? Someone warned me that I should be careful when ever I declare a field static unless the field is either a WeakHashmap or a WeakReference. Is it true?
Any suggestions is greatly appreciated!

Please don't crosspost. It cuts down on the effectiveness of responses, leads to people wasting their time answering what others have already answered, makes for difficult discussion, and is generally just annoying and bad form.

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device (iPhone) using debug build. When running with a release build, the result handler is never called (nor is the fault handler called). Viewing the BlazeDS logs in debug mode, the call is received and send back with data. I've narrowed it down to what seems to be a data size issue.
I have targeted one specific data call that returns in the String value a string length of 44kb, which fails in the release build (result or fault handler never called), but the result handler is called as expected in debug build. When I do not populate the String value (in server side Java code) on the object (just set it empty string), the result handler is then called, and the object is returned (release build).
The custom object being returned in the call is a very a simple object, with getters/setters for simple types boolean, int, String, and one org.23c.dom.Document type. This same object type is used on other other RemoteObject calls (different data) and works fine (release and debug builds). I originally was returning as a Document, but, just to make sure this wasn't the problem, changed the value to be returned to a String, just to rule out XML/Dom issues in serialization.
I don't understand 1) why the release build vs. debug build behavior is different for a RemoteObject call, 2) why the calls work in debug build when sending over a somewhat large (but, not unreasonable) amount of data in a String object, but not in release build.
I have't tried to find out exactly where the failure point in size is, but, not sure that's even relevant, since 44kb isn't an unreasonable size to expect.
By turning on the Debug mode in BlazeDS, I can see the object and it's attributes being serialized and everything looks good there. The calls are received and processed appropriately in BlazeDS for both debug and release build testing.
Anyone have an idea on other things to try to debug/resolve this?
Platform testing is BlazeDS 4, Flashbuilder 4.7, Websphere 8 server, iPhone (iOS 7.1.2). Tried using multiple Flex SDK's 4.12 to the latest 4.13, with no change in behavior.
Thanks!

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.

How can I disable data access on C1-01 ?

I have a C1-01, for emergency use only. Today it displayed an unsolicited "Download Failed", message, and sure enough, my paygo account had been emptied. How can I prevent all data access, ie attempts to update firmware, internet access, etc?
TIA, Richard
Solved!
Go to Solution.

easiest way is to contact your network operator and ask them to disable your data plan and all internet access on your device. there are also a few miscellaneous settings in your phone, so you can try deleting access points if they are displayed in the Settings. i would check the phone Settings menu and the Web browser settings for items that you can turn off / disable.

How to get Current Log in BO user name in data access driver

In universe, to get the current log in user is via @Variable('BOUSER').
Right now, I need to be able to get the user name in the data access driver. I am writing a customized data access driver because we need to patch some where clause on the the query generated by the universe based on the logged-in user info. I only think of using end_sql parameter or adding an universe level filter to patch the @Variable('BOUSER') to the query, which would not work if user want to use customized query.
Can anyone tell me how to get currentBO user name from connection server ? or how @Variable('BOUSER') is translated into the logged-in user name in the universe?

Shweta,
The link you provided was the Auditor guide for BO 6.x, I'm not sure it that is going to help Karen or not.
Karen,
There is function called connection
(usage: =connection([Query Name]), where [Query Name]
denotes the name of the tab for the query under Edit Query)
Here is some of the output from connection:
4;ODBC18;MS SQL Server 2000166; VERSION=7; USER=xxxxx;
PASSWORD=; DBTYPE=Relational; DATABASE=xxx_xxxx;
ODBC_USER=xxxxxx; ODBC_PASSWORD=; BO_DSN=xxxx_xxxx;
BO_DRV_CONNECT_MODE=0; 224; VERSION=6; Name=xxxxx; Shared=4;
LoginTimeout=600; Timeout=600; Pool Time=60; Array Fetch Size=10;
Array Bind Size=5; RecommendedLenTransfert=1000; Password_Encryption=x;
AliasTable=; MeasureDimension=; Hint=; ConnectInit=; ArrayFetch=1;
I'm not sure if this info helps out either, being that connection provides info on a post-processing basis and it sounds like you need to get out ahead of the SQL generation. The @variable('bouser') would seem like the place to be, however, in allowing custom SQL to take place you loose the bouser due to an individual could customize the SQL to the point that it gets unwantingly yanked out. The end_sql might be your answer...
Thanks,
John

I do not know your EJB Service. But you should pass the credentials of the current logged on portal user to your service. That's not by default I think.
I had a similar problem with CAF developed webservices. I had to turn on permission checks in my web service and passed the credentials via logon ticket.

Hi,
Thanks for your suggestion's here i am going to run the datapump script so while i am running in workbench it is throwing data access error.So as you guy's suggested i created one import format and added this script to that import format which is added to one of my location even it is throwing the same error.I am getting the error at this sentence   "strWorkTableName" I want to know what is this where it reflect's?So my question is Is there any difference while running data pump or integration script.Please let me know a detailed navigation steps to run this script's with out data access error to run these kind of scripts.

Issue with Enterprise Library's Data Access Application

I do not know if I have the correct forum for this post. I hve put it in what I believe is the most likely best forum, but please move this if there is a more germane forum for it.
I have inherited a solution (C#) which uses the reference Microsoft.Practices.EnterpriseLibrary.Data. The reference was included with the codebase I inherited, there are no missing references.
When the library is called with:
Microsoft.Practices.EnterpriseLibrary.Data.ExecuteDataSet("configConfigurationKeysSelect", parameterValues);
It complains with the runtime error:
[InvalidOperationException: The stored procedure 'configConfigurationKeysSelect' doesn't exist.] (I have put the full trace below)
This is true, there IS no stored procedure  'configConfigurationKeysSelect' but there is a table named  'configConfigurationKeys.'
I assumed this stored procedure is built on the fly to select from that table? Must I do something regarding  Enterprise Library's Data Access Application so that this works on the system I am running it on? (I am simply accessing the references
included with the sourced for this, nothing else). I am looking for some guidance here, and thanks in advance.

0187 EAIA Data access error Lenovo Twist

When the error happend the systemboard was replaced (0187 EAIA Data access error on startup), and the error came back up again. Replaced the systemboard again and the error persists. Can't update eprom serial information because of this error. I currently have about 6 machines doing the same thing, and was wondering if anyone else had experianced this issue?

I get the same error on a brand new Lenovo Thinkpad S540 (+-1 month old). Besides that first issue I'm also getting these errors:
2200: Machine Type and Serial Number are invalid
2201: Machine UUID is invalid
These occur together and only in about one out of every ten boots.
Curious what's wrong here.

"unable to connect to the data access service" installing report server

Trying to do a 2 server SCOM 2012 R2 install on Server 2012 w/SQL 2012. Management server and operations console on one, and SQL, web console, and reporting server on the other. When I get to the web console and reporting server install, and
the "Specify Management Server" screen, I input the 1st management server name and it gives me a red X with the message:
"Unable to connect to the Data Access service for this management server. Ensure the Data Access service is running and that the service, the management group, and setup are all the same version."
Here is the setup log error:
"Info: :Could not connect to Management Server: scom-app with exception: Threw Exception.Type: System.ArgumentException, Exception Error Code: 0x80070057, Exception.Message: Version string portion was too short or
too long."
I don't see the "Data Access" service in services on either server. I followed all of the setup prereqs in SCOM 2012 unleashed book, and also referenced this article for setup advice:
http://blogs.technet.com/b/kevinholman/archive/2013/01/16/opsmgr-2012-sp1-quickstart-deployment-guide.aspx
Everything seems to be working until I get to this point.
Thank you for any help you can provide,
Dan

Hi Tom,
1. Did the setup complete successfully on the MS and Console server?
>>>Yes, without issue
2. You do not see the service "System Center Data Access Service"
>>>I do indeed see it on the MS and Console server, it is set to Auto and running. (I also tried rebooting this server and retried, no help)
3. Is the Windows Firewall enabled?
>>>It has symantec endpoint protection. I disabled symantec completely on both servers and retried, no help.
Thx,
Dan

How to Install Oracle Data Access Components (ODAC) on Windows Server 2003?

I recently installed "32-bit Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio" on my computer (Windows 7, 64bit). Everything seems fine and I can develop and run my application in Visual Studio 2010 and IIS 7.
Now, when I deploy my application to the Server, it raises error:
Exception: System.TypeInitializationException: The type initializer for 'Oracle.DataAccess.Client.OracleCommand' threw an exception. ---> Oracle.DataAccess.Client.OracleException: The provider is not compatible with the version of Oracle client
Obviously I need to install ODAC on the server, too. My server is:
- Windows 2003 32 bit R2 (I know, I know!)
- IIS 6
So. I downloaded the same installation from Oracle website (ODAC 11.2 Release 5 and Oracle Developer Tools for Visual Studio [11.2.0.3.20]) and installed it on the server. But still getting the same error.
PS: When I was installing, I chose Oracle Data Access Component for Oracle Client 11.2.0.3.20 in Oracle Universal Installer. hmmmm. Should I choose "Oracle Server" instead? Screenshot

ODP.NET, Unmanaged Driver uses unmanaged dependencies in the Oracle Client. The error you see means you have another Oracle Client installed on the Win2003 machine and ODP.NET is attempting to load the incorrect Oracle Client version, rather than the version you installed ODP.NET with.
What you need to do is direct ODP.NET where to find the correct version of its unamanaged Oracle Client dependencies. This will be generally the bin directory of your Oracle Client home that was installed with ODP.NET.
You can learn more about DllPath here:

The Date Accessed attribute is resetting to all the files in a folder

Hi all,
I have an issue that the "Date Accessed" attribute is often resetting to all the files in a folder if i open single file as this folder is from File server mapped as Drive to me. This is happening to all the users whoever connect to that fileserver
and i see same issue from RDP as well. is there any option to check which is resetting the "Date Accessed" attribute to all the files. The Date Access attribute is simillar to Date accessed and Date modified. We need to fix this issue as it is related
to security concern for us. The file server is windows 2008 R2 and the client machines are windows 7.
Side note: I can see that there is no software, antivirus, offline sycn is causing this issue.
Thank you,
Sampath
P.Sampath

Hi,
It seems that some specific process accessed the files and updated the attribute. You could configure auditing on the shared folder. Then you can go through the auditing log to check which process is doing the read operation on all these files.

Given an object that is stored in a database, is it better to have the database access code in a constructor method, or a data access layer object? E.g. I have a Person class
public class Person{
int Id;
String name;
int age;
}When I want to read a person's details from the database, I could use a constructor something like this:
public Person(int id){
Connection con = getDatabaseConnection();
ResultSet rs = con.createStatement().executeQuery("Select name, age from person where person_id = " + id);
rs.next();
this.name = rs.getString(1);
this.age=rs.getInt(2);
}Or I could use a method in a data access object :
public Person getPerson(int id){
Person p = new Person();
Connection con = getDatabaseConnection();
ResultSet rs = con.createStatement().executeQuery("Select name, age from person where person_id = " + id);
rs.next();
p.setName(rs.getString(1));
p.setAge(rs.getInt(2));
return p;
}It seems to me that the constructor approach has two advantages
(1) the SQL code is kept in the relevant class (so if I want to add a field to Person, I only have to make changes to the Person class)
(2) I don't have to have a setter method for each field
Is one or other of these ways generally recognized as 'best practise'?

But then, on the other hand, everytime a Person gains a new field that's two places you have to change it. if the persistence interface is written in terms of the object and uses ORM, I don't have to touch the implementation. all i have to do is update the object, the database, and the mapping - just like you and your home brew ORM.
besides, so what? i'd fear the resource leak, bad layering, more difficult testing more.
Actually lately I've used annotations to label setters with database field names and run a simple home brew ORM to convert rows into objects even when not using a more complex persistence manager.home brew ORM? why is that necessary when you can choose from hibernate, ibatis, jdo, jpa, etc.? that's just nuts.

How to check if Oracle Data Access Components is installed?

How to check if Oracle Data Access Components is installed and version on my computer?
Also How to check if Oracle Data Provider is installed and version?
TIA

Regedit HKLM->Software->Oracle. See what's there...
At the very least, that can give you paths and can check file versions from there.

Windows 7, file properties - Is "date accessed" ALWAYS 100% accurate?

Hello,
Here's the situation: I went on vacation for a couple of weeks, but before I left, I took the harddrive out of my computer and hid it in a different location. Upon coming back on Monday (January 10, 2011) and putting the harddrive back in my computer, I
right-clicked on different files to see their properties. Interestingly enough, several files had been accessed during the time I was gone! I right-clicked different files in various locations on the harddrive, and all of these suspect files had been accessed
within a certain time range (Sunday, ‎January ‎09, ‎2011, approximately ‏‎between 6:52:16 PM - 9:06:05 PM). Some of them had been accessed at the exact same time--down to the very second. This makes me think that someone must have done
a search on my harddrive for certain types of files and then copied all those files to some other medium. The Windows 7 installation on this harddrive is password protected, but NOT encrypted, so they could have easily put the harddrive into an enclosure/toaster
to access it from a different computer.
Of course I did not right-click every single file on my computer, but did so in different folders. For instance, one of the folders I went through has different types of files: .mp3, ,prproj, .3gp, .mpg, .wmv, .xmp, .txt with file-sizes ranging from 2 KB
to 29.7 MB (there is also a sub-folder in this folder which contains only .jpg files); however, of all these different types of files in this folder and its subfolder, all of them had been accessed (including the .jpg files from the sub-folder) EXCEPT the
.mp3 files (if it makes any difference, the .mp3 files in this folder range in size from 187 KB to 4881 KB). Additionally, this sub-folder which contained only .jpg files (48 .jpg files to be exact) was not accessed during this time--only the .jpg files within
it were accessed-- (between 6:57:03 PM - 6:57:08 PM).
I thought that perhaps this was some kind of Windows glitch that was displaying the wrong access date, but then I looked at the "date created" and "date modified" for all of these files in question, and their created/modified dates and
times were spot on correct.
My first thought was that someone put the harddrive into an enclosure/toaster and viewed the files; but then I realized that this was impossible because several of the files had been accessed at the same exact time down to the second. So this made me think
that the only other way the "date accessed" could have changed would have been if someone copied the files.
Is there any chance at all whatsoever that this is some kind of Windows glitch or something, or is it a fact that someone was indeed accessing my files (and if someone was accessing my files, am I right about the files in question having been copied)? Is
there any other possibility for what could have happened?
Do I need to use any kinds of forensics tools to further investigate this matter (and if so, which tools), or is there any other way in which I can be certain of what took place in that timeframe the day before I got back? Or is what I see with Windows 7
good enough (i.e. accurate and truthful)?
Thanks in advance, and please let me know if any other details are required on my part.
P.S. The harddrive is NTFS.

Never mind. Someone else already answered this for me:
"I use last accessed-created date time stamps all the time when troubleshooting-investigating software installs, its been very accurate in my uses of it in NTFS file systems.
Since some of the dates are while you were gone, I assume it was several days to a week, I would say someone did access those files.
These timestamps along with other data are used by computer forensics teams to reconstruct what a user did on a computer.
Experienced Hackers use software to alter these time stamps to cover their tracks when breaking into computer systems."

Additionally, I just now found out what happened. Someone else found the harddrive and thought it was theirs (since it was identical to one they had been missing), so they put it in their computer and scanned it with an anti-virus software. They realized it
wasn't theirs and then put it back in the place I had hidden it.
In my original question, I stated a possible theory that someone may have copied the files, but I later realized that copying in itself doesn't affect the "date accessed" of the original/source file, but rather only the "date accessed" of
the copy.
Thanks to all those that may have read my question.
