Scrum And Xp From The Trenches
by Henrik Kniberg
He doesn’t offer a lengthy description of what Scrum is; he refers us to some simple websites for that. Instead, Henrik jumps right in and immediately begins describing how his team manages and works with their product backlog. From there he moves through all of the other elements and practices of a well-run agile project. No theorizing. No references. No footnotes. None are needed. Henrik’s book isn’t a philosophical explanation of why Scrum works or why you might want to try this or that. It is a description of how one well-running agile team works.
This is why the book’s subtitle, “How We Do Scrum,” is so apt. It may not be the way you do Scrum, it’s how Henrik’s team does Scrum.

Flush the buffer cache in [tag]Oracle[/tag]. This invalidates also the read cache, so the query performance results provides from the physical reads time.
alter system flush buffer_cache;
This command is not available prior to 10g. It flushes the buffer cache in the SGA.
9i had an undocumented command to flush the buffer cache:
alter session set events = 'immediate trace name flush_cache';

With the new row_number() feature of the MS SQL Server 2005, now it’s very easy to implement pagination: get data rows page by page to avoid the retrieve too much data at same time. The new feature it’s very similar to the Oracle ROWUM.
The prepare statement could be like the follow:
-
SELECT * FROM ( SELECT row_number() OVER (ORDER BY id) AS resultNum, id FROM table_name) AS numberResultsWHERE resultNum BETWEEN ? AND ?

Retrieving identity column values in JDBC applications:
You define an identity column in a CREATE TABLE by specifying the IDENTITY clause when you define a column.
This feature is defined in the JDBC, and implmented in the MS Sql Server 2005, not in the older version. For Oracle database this is not implemented, but the common solution of the rownum can be used instead.
1.Set the prepared statement to get the identity column from DB:
or
2. Get the generated values from the statement
-
rs = stmt.getGeneratedKeys();
-
while (rs.next()) {
-
rs.getBigDecimal(1);
-
}
