I have a question about oracle commit and transactions. Following scenario:
Process A performs a single sql-INSERT into a table and commits the
transaction. Then he informs process B (ipc) to read the new date. So
process B starts "select ..." but does not get the previously inserted
row. The timespan between commit and select is very short.
(NOTE: two different sessions are used)
Questions:
1.) Does commit when returning from call...

We use DB2 Connect v 7.2 FP7 in Windows NT hitting a OS/390 DB2 v7.1
database. We have a Websphere (java) application that issues dynamic
SQL. Most of the time when we issue dynamic SQL SELECT statements,
like through a DB2 command window, the command will be processed using
a package like SQLLF000 which uses an isolation level of Cursor
Stability. However sometimes in the Websphere application when a
dynamic SELECT statement is issued...

I have been researching ADO.NET in order to train our programming
staff. I am curious if someone would know what the default isolation
level is with and without a transaction. Furthermore, if I specify the
isolation level on the transaction object, which one is the most like
cursor stability? Is it read commited?
Any other opinions/best practices regarding ADO.NET are welcome. I
have been reading the redbook DB2 for UDB V8.2 on the...

Dear All,
I have a VB6.COM program using a VB6.COM DLL, which in turn uses ADODB that
performs various bits of SQL.
I have re-written the VB6.COM DLL in C#.NET (with a VB6 shell), which uses
the ADODB.Interop library supplied with .NET. The VB6.COM program above
calls this C#.NET library in an effort to perform the equivalent
functionality.

Hello.
I am developing the application (VBA&ODBC, to be exact) which
periodically calls the stored procedures in the IBM DB2. A few of the
procedures require executing with isolation level RR ( ANSI
"SERIALIZABLE" ), not the default; default is CS (ANSI "Read
Committed")). The procedure language is SQL.
According to the documentation, I can adjust procedure *run*-time
isolation level by setting *compile*-time dataserver-wide option

Is there some way to track the isolation level of an indivual SQL
statement submitted via JDBC in a snaphot or some other similar means?
I have JDBC programs that are changing the isolation level via
Connection.setTransactionIsolation(int level) method, such as
TRANSACTION_SERIALIZABLE or TRANSACTION_REPEATABLE_READ and I need to
verify that in DB2 at a SQL statement level. I don't see isolation
level in a snapshot for Dynamic SQL.

I have a question about the "readCommitted" transaction isolation level.
I have a client that is updating a record on a table.
I suspend the execution after the UPDATE but before the commit statement.
Than another client is trying to read the same record.
As transaction isolation is set to "readCommited" I expected that the second
client will read the old version of the record (before the update).
Instead, the second client hangs and...

Hi everybody,
there are two ways to change the isolation level:
For instance i would like to change the isolation level to rs
1. "db2 change isolation to rs"
2. "db2 set current isolation rs"
When i use the first one and then "db2 values current isolation" to verify if the change was successful, i won't get anything. But when i use the second one and then invoke the command "db2 values current isolation", i will see that the...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
