Database reply questions

Hi,
i'm testing database reply.
i've a test workload to reply on another test environment.
the target machine is more powerfull then the source, but in reply phases the green reply bar
is more long than capture bar.
Now there is no activity but replay bar still increase.
What can i check?

You need to explain your problem more.
What do you mean by database reply? Do you mean replay?

second question can I use my secondary ACS for the DataBase repository?

Hi,
You should use an nfs server, sftp or ftp repository for backups only, something that is dedicated for storage. I would not recommending using anything that is used for production which needs internal storage to take on the task of managing another applications data.
As far as the the first question, i am not talking about the purging, i am talking about the scheduled application backups:

Database connection question...

i am using Java 1.5.0_06 and to connect to MySQL database i use Connector/J and the following code:
try {
Class.forName("com.mysql.jdbc.Driver");
} catch(java.lang.ClassNotFoundException e) {
System.err.print("Main: ClassNotFoundException: ");
System.err.println(e.getMessage());
return;
try {
con = DriverManager.getConnection(dburl);
ps = con.prepareStatement(
I was told i should be using a DataSource to do connection pooling and i have read over the info and downloaded jdbc2_0-stdext.jar and i am using MySQL and windows XP pro.
the code looks like this
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/InventoryDB");
Connection con = ds.getConnection("myUserName", "myPassword");
then i just use con as i have already in my code.
Can someone please point me in the right direction to get this working.
I read this:
A systems administrator or someone working in that capacity deploys a DataSource object. Deployment, which involves setting the DataSource object's properties and then registering it with a JNDI naming service, is generally done with a tool. As part of the registration process, the systems administrator will associate the DataSource object with a logical name. This name can be almost anything, usually being a name that describes the data source and that is easy to remember. In the example that follows, the logical name for the data source is InventoryDB . By convention, logical names for DataSource objects are in the subcontext jdbc , so the full logical name in this example is jdbc/InventoryDB .
i have goggled but can't seem to find out exactly what i need to do next.
I can't find the "tool" and have to be honest i am lost lol.
can the The JDBC 2.0 Optional Package work with Java 1.5.0_06?

i am using Java 1.5.0_06 and to connect to MySQL database i use Connector/J and the following code: i updated it to use manual connection pooling like so:
final String dburl = "jdbc:mysql://localhost/......";
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver");
} catch(java.lang.ClassNotFoundException e) {
System.err.print("Main: ClassNotFoundException: ");
System.err.println(e.getMessage());
return;
try {
DataSource dataSource = setupDataSource(dburl);
con = dataSource.getConnection();
con.close();
public static DataSource setupDataSource(String connectURI) {
ObjectPool connectionPool = new GenericObjectPool(null);
ConnectionFactory connectionFactory = new DriverManagerConnectionFactory(connectURI,null);
PoolableConnectionFactory poolableConnectionFactory = new PoolableConnectionFactory(connectionFactory,connectionPool,null,null,false,true);
PoolingDataSource dataSource = new PoolingDataSource(connectionPool);
return dataSource;
so i compiled and ran it and it worked no problem but my question is that this is a server that does some db work upon starting and then waits for clients like so:
while (listening)
new PSMultiServerThread(serverSocket.accept()).start();
so once i am in PSMultiServerThread what exactly do i need to do?
i know i don't need to do this again:
Class.forName("com.mysql.jdbc.Driver");
but do i need to do this again:
DataSource dataSource = setupDataSource(dburl);
i geuss i have to to declare the variable lol.
and do i include this code in the PSMultiServerThread
public static DataSource setupDataSource(String connectURI) {
ObjectPool connectionPool = new GenericObjectPool(null);
ConnectionFactory connectionFactory = new DriverManagerConnectionFactory(connectURI,null);
PoolableConnectionFactory poolableConnectionFactory = new PoolableConnectionFactory(connectionFactory,connectionPool,null,null,false,true);
PoolingDataSource dataSource = new PoolingDataSource(connectionPool);
return dataSource;

Multiple Database Servers Question

Hi,
Please forgive this ignorant question, but can someone tell
me how one would go about using multiple database servers?
Just as there comes a time where one would need more than
one web server and would need to use a load balancing
solution, what happens when one would need more than one
Database Server?
How does one go about implementing that solution?
Is there some way to have two database servers carrying the
same information with some kind of load balancing solution
in front of it(?) or does one place some tables on one
Database
server, and other tables on the other database server?
(I have no clue as to how things would work.)
Thanks in advance,
Joe

Microsoft SQL allows for clustering of SQL databases, so for
instance two servers connected to a fileshare and a virtual address
shared across the two physical boxes. Database connections are made
to the virtual addres which will then be handled by the active
node. Becuase a database is ultimately a file(s) on a disk it can
only be attached to one node at a time so you end up with an
active/inactive cluster.

Database array questions

Disclaimer: I am new to DB's.
I'm looking at creating a MySQL database to hold tests done on DUTs (each with a specific serial). In theory, each DUT undergoes 3 tests. Each test produces a 401x9 2D array of DBLs. I am not concerned with the write speed to the DB, but I do want to optimize the read of the DB (potentially may need to retrieve 1000+ of these 2D arrays as fast as possible). I have the DB Toolkit; using LV 8.5. Questions:
1. I have seen two different ways to save a 2D array in a DB mentioned: first, writing one row at a time with the DB Insert vi, resulting in a 2D array in a table (which is slow writing) or second, changing the 2D array to a variant and using the DB Insert vi, resulting in a single cell in a table. I know I can use other methods (parameterized vi, sql commands, user defined functions on the DB server, please do comment if you have found drastic performance increase with these methods), but of the two ways of storing a 2D array, can I read a 2D array from a table faster than reading a 2D array from a single cell? Whenever I need this data, I will read it all (i.e. I will never have to search for certain data within these individual 2D arrays)
2. I may have installed the 8.2.1 DB toolkit, because the Database Variant to Data vi/function does not drop onto the Block Diagram when I drag it from the palette, and the Help has ???. I assume this is because it just points to the normal Variant to Data, which in 8.5 is in a subpalette as compared to 8.2.1. Any quick way to fix this?
3. Any other general suggestions for a DB newbie? I've been trying to derive best practices from KB aritcles, this forum, and the web, but there is so much information and so many varying opinions I find it hard to narrow down best practices.
Michael

Hi Miguel,
It looks like you are embarking on a very interesting project. Although you probably have seen many of the following documents, I've linked a few to get you started.
Discussion forum using LabVIEW to read from tables
Developer Zone article about developing a test system
Knowledgebase article about imitations of speed with database toolset
As far as your first question, I would suggest trying out both methods with simple code and testing with a small amount of values to determine which one will be the fastest.
Good luck with your project!

Simple java/mysql database application question about triggers

I am planning a new database application using java and mysql. I may want to use some triggers to automatically update the tables when a change is made. my question is this: If I write the trigger, and I use Java to modify the database, will java automatically pause and let the trigger finish doing its task before it continues? what if it writes more to the table before the trigger is finished modifying the table? how do I get java to pause and let the trigger finish?
thanks for your response

It doesn't have anything to do with java at that point.
When you execute, for example, an insert statement, then the database executes that statement. The database (not java, not the driver) decides with that statement is complete. Control returns to java when the database decides that execution is complete.
And except for tricks that one might do (or attempt to do) via SQL or triggers then when the statement execution finishes then everthing has completed running.

Create View from Database Links - Question

Question
I'm missing something simple.
I'm trying to create a view, from a Database Link.
CREATE VIEW view_name
AS SELECT a.*
FROM schema.tablename@dblink a;
When I run this in the SQL Commands window.
I get this error message.
ORA-00933: SQL command not properly ended
What am I missing? Any help is appreciated...

CREATE VIEW vw_name
AS SELECT a.*
FROM [email protected] a;

 
1) User (schema) which is creating view must have proper db_link to source database. For that try this for testing purpose:
select 1 from [email protected] 
If this fail then db_link is not ok! This step is absolute must to go any further step to!!!
 
2) when db_link is set, then your view should be named as:
CREATE VIEW vw_name
AS SELECT *
FROM schema_name.[email protected]; 
please pay attention to "schema_name", because from remote side every table is in some schema so it really need declaration of owner schema.
 
Hope this helps...

I have some database related questions

hey all
i am currently designing a java GUI program for a dvd renting shop.
this program obviously needs a databse, i was just wondering how much possibly a database on a home pc could hold data because this shop have about 15000 DVD title and about 1500 client so i was wondering how much a mySQL databse table could hold....
i also have another question...this shop have an access database...my question is can i use the existing database and querie it from my java program??? do i need a driver ??? can i querie an acces databse just like a regular SQL databse(e.g. SELECT * FROM TABLENAME) ????

You will not have issues even with Access with that few a number of rows. Disk is really the only limitation on the size of the database. (There can be O/S or database specific limitations, such as 2GB of total size). So, do not worry about how many records.
When you truly get a large number of records (tens of millions plus) or you are joining two large tables, then you can have performance issues. Good use of primary keys, indexes and database design can limit this issue.
i also have another question...this shop have an
access database...my question is can i use the
existing database and querie it from my java
program??? do i need a driver ??? can i querie an
acces databse just like a regular SQL databse(e.g.
SELECT * FROM TABLENAME) ????You can use Access, mySQL, Postgres or any number of other databases. Each will require (and will have on their site) a JDBC driver that you need to have on your application's CLASSPATH. My recommendation would be mySQL or Postgres. Both are free and excellent quality.
As an aside, you should rarely SELECT * from any table (other than a code or lookup table). Use a WHERE clause to limit results. What user would possibly want to scroll through ALL 15,000 records? :^)

MySQL Database Structure Question

This is probably going to seem a little odd, but I need some outside opinions. I'm using Dreamweaver CS5 to build a business website. When all is said and done, it's going to have around 20,000 items (not anytime soon, but it'll get there). I'm using a dynamic data set up to load the inventory because I'm way too lazy to build that many pages and links one at a time.
The corporate chain has two sections, lighting, and electrical supply. I want the database to hold the product ID(of course), name, description, image(this is part of where the question comes in), price, sale price(discounts not our cost), an enum field for whether or not the item is discontinued(for our own records), size / weight for shipping reasons, and if reality is permitting, a field for color selection of the products.
My original idea was to have two tables, one for lighting, one for electrical. Somebody pointed out to me that this could fail because they pointed out that some of the items might have multiple images, which is true. Some of the items (like some of the fans we sell) have different colors but still cost the same. They suggested I set the images up in a seperate table and use a foreign key. but that changes my entire structure.
Does anyone mind offering ideas on how I might set that up to avoid data redundancy and other problems that might pop up due to repeat listings? I've got the images all with unique names (in the case of the same product in different colors, I added a color code like pb for polished brass, etc.) That person had an excellent point on multiple tables, so now I'm wondering about a better and more reliable structure.

I'm ok with PHP, and usually pretty good with databases. Right now I've got enough sample stuff to build a smaller scale prototype with about 200 products, from both lighting and electric. Believe me, I haven't really done much more than start with the layout, because the many to many relationships just didn't occur to me. Pretty much going solo on this project with occasional advice from one co-worker who's good at his job but extremely busy, so I think I just got a little to close to it and overlooked some clear and obvious problems. As far as requirements, I'm using a 3 column div tag layout, the left column being the nav bar with the product categories. When they click one of those, it should display that category (image, name, price) with the clickable name and thumbnail image in the middle, and from there they click the product they want to see and it'll display the full size image and full description on the right column.
Set requirements...wish I had a clear list, but the bosses are pretty much illiterate in this area of computers, so I'm on my own with that. That's all I'm hoping to get out of the database is that three column layout. I figure I'll make a changeable nav bar later so customers can switch from one store to the other and the nav bar goes from there.
We're hoping to get the database to have the fields I mentioned for now (at least for initial testing) and maybe add an inventory tracking function so we know how many we have throughout the chain. We're not worried about that part now, just getting them up and selling cuz our current inventory system works just fine. How would 10 or more tables be better? Just breaking down the amount of products to be searched at a time, or is that how detailed you think it should be built? Don't worry, I wasn't hanging everything on a two table set up, I knew there would be room for much improvement.
Current basic layout:
Lighting / Electric Tables Image table: ID (either the product ID without the color code or maybe the document path), category(lighting / electric), subcategory (fan, lamp, etc)
id
class
category
description
price
sale price
discontinued
size
weight
That's what I've got so far, sorry for the weird way that list pasted....

Database Vault Question on a Test Server

I have a question about database vault. Say I have Database Vault protecting the DBA from viewing table XYZ in producion. If the DBA takes a backup of the production database and clones it onto another test server is table XYZ still protected on that test server? Or because Database Vault is not running against this test server does that mean that the table is wide open now for the DBA to see? Thanks for any help on this.

No, mysql_query() just needs the query. Your problem lies
with quotes in
the query itself. A couple of the values are not in quotes.
There should
also not be a comma before WHERE.
$query_updateAvailability = "UPDATE tbl_availability
SET
satStatus='".mysql_real_escape_string($_POST['satStatus'])."',
sunStatus='".mysql_real_escape_string($_POST['sunStatus'])."'
WHERE

Newbie Database Access Question

I am familiar with SQL and database access from web programming, but have never done these things from within a Java application. My google searching has been fruitless thus far, so I'd appreciate any references to beginner's guides about how to query databases from a Java app and manipulate the resulting recordsets. Anything on Access db's would be ideal.
TIA,
John

Thanks for the reference. I have a question about this section of the tutorial:
http://java.sun.com/docs/books/tutorial/jdbc/basics/connecting.html
Under the section "Loading the Drivers" is the following paragraph:
Loading the driver or drivers you want to use is very simple and involves just one line of code. If, for example, you want to use the JDBC-ODBC Bridge driver, the following code will load it:
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Your driver documentation will give you the class name to use. For instance, if the class name is jdbc.DriverXYZ , you would load the driver with the following line of code:
Class.forName("jdbc.DriverXYZ");My question is: How do I decide which driver I need for connecting to an Access db on a Win XP machine? Is there perhaps another reference which answers these kinds of questions?
Thanks again,
John

Project Server (SharePoint) - Database Collation question.

Hi,
I have been looking at the performance of our SharePoint database server and one of its uses is Project Server.
Our databases are set as follows
Project Server Databases (Latin1_General_CI_AS)
SharePoint Server Content Databases (Latin1_General_CI_AS_KS_WS)
TempDB (Latin1_General_CI_AS)
It seems that the Project Server databases should be (SQL_Latin1General_CP1_CI_AS):
https://technet.microsoft.com/en-us/library/ff800813(v=office.14).aspx
e.g.
Database
Collation
Project Server Archive
SQL_Latin1_General_CP1_CI_AS
Project Server Draft
SQL_Latin1_General_CP1_CI_AS
Project Server Published
SQL_Latin1_General_CP1_CI_AS
Project Server Reporting
SQL_Latin1_General_CP1_CI_AS
SharePoint Server Content
Latin1_General_CI_AS_KS_WS
I may be worrying unnecessarily but my understanding was that the tempdb should be the same collation as the user databases (where possible). With the SharePoint content and the Project Server databases on the same instance this is not possible.
Should I...
1. Not worry about it (the performance impact is negligable).
2. Create seperate instances so that the TempDB can match the user databases (I am worried that the overhead of an extra instance will be more than the overhead of different collations).
3. Implement Contained/Partially contained databases (new possible option)
4. Something else?
Also how bad is it that the Project server databases are Latin1_General_CI_AS rather than SQL_Latin1General_CP1_CI_AS.
Thanks in advance
Shaun

Hi Prasanna,
thank you for taking the time to respond.
From the link - I read this as Microsoft insisting that you use Latin1_General_CI_AS_KS_WS for the SharePoint content databases and recommending it for the system databases including TempDB?
Our TempDB is not the same collation as the SharePoint content databases but the same as the Project Server databases. Which brings me back to my original questions.
From the Technet article:
The following TechNet Article talks about the SQL Server collation for the SharePoint databases
http://technet.microsoft.com/en-us/library/cc288970.aspx#section1
“The SQL Server collation must be configured for case-insensitive. The SQL Server database collation must be configured for case-insensitive, accent-sensitive, Kana-sensitive, and width-sensitive. This is to
ensure file name uniqueness consistent with the Windows operating system.”
However, we do not support changing the default collation (Latin1_General_CI_AS_KS_WS) for SharePoint databases to any other collations (CI, AS, KS, WS).
We support any CI collation for the SQL instance (for master, tempdb databases). However we
recommend using Latin1_General_CI_AS_KS_WS as the instance default collation (master, tempdb databases).

Database Driver Question

Hello,
I wrote an application with the following statements:
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
} catch(Exception ex) {
setError("Can't find Database driver class: " + ex);
return;
The database driver can be found.
However, when I used the above in an applet and used appletviewer to run the applet, the message said
Can't find Database driver class:...........
(The database I tried to access was Oracle9i.) Why? Help will be appreciated.
myao1

What the question was then? The code is using the jdbc-odbc bridge. That works in an application and fails in the appletviewer. The question is why does it fail in the second while working in the first.
You suggested several inappropriate things.
For instance
You need to go to Oracle website. A lot of info there.
There is no information there about using the jdbc-odbc bridge.
You then proceeded to provide code for a connection using the Oracle driver. Which of course has nothing to do with the jdbc-odbc bridge nor why it doesn't work.
If the first thing in your post was to suggest that the poster's problem might be fixed by using a different driver then your answer would have made sense.
Given that you do not know the experience level of the poster your answer might lead them to believe that they are using the jdbc-odbc bridge incorrectly. And that is not the case.
And even if your solution fixes the problem it still doesn't answer the question as to why the appletviewer doesn't work.
jschell, if you are so
understanding, maybe you can explain, because I see
your job is to point out other people mistakes in
understanding other people. Yes. And I also point out answers that are wrong for the question. Which yours was.
And it happened that those
people who were misunderstood (already properly
reprimanded) cannot stand for themselves. I presume that a fair number of people that come here are very inexperienced. If that was not the case then I would presume that there would be more people answering questions on a daily basis then there are.
So they might not understand that your answer had nothing to do with the question. So they might not point it out. Or someone else might be searching the the same solution and come across your answer. And they wouldn't understand that it had nothing to do with the question. By making it explicit there can be no confusion.
It should be you stepping forward to protect... I see.
And I remember you don't like flowers. Sorry I don't know what the reference to flowers means.

Restart primary database - stupid question

I have a 10.1 primary database and have set, via OEM, DG with a physical standby database on another server.
I can use DG to switch the standby from read-only to standby and back.
My studpid question is that I need to stop and restart my primary database and I'm worried that if I shutdown the primary database that DG/OEM will see it down and try and set the standby as the primary.
I'm not sure where to look to see if it will automatically fail over or not. In this case I'm hoping not and that in a failure situation in the future I'd have to manually switch roles to make the standby database the primary database.
Hope it all makes sense?
James.

If you dont have fast start failover enabled then shutting down the primary will not affect the standby and no auto failover will occur.
Have a look in OEM on the DataGuard screen:
Under the Overview section - if it says the below then you can restart your primary without anything being initiated:
Fast-Start Failover Disabled

Siebel Sample Database Access question

I am from the Oracle EBS world and am a newbie to Siebel. I want to try out Siebel.
Just like Siebel sample database EBS has a sample instance called VISION. There are few Oracle Partners that give free online access to the VISION instance.
My question is are there any websites that has free Siebel Sample database access.
I understand that installing Siebel sample database on a pc is relatively straight forward but I'll take that route if there are no other option.
TIA
Harsha

Hi,
That is the easiest way (installing Siebel Sample DB) i guess it's the only way.
