An optimistic approach always assumes that everything will be OK and that conflicting data modifications are rare. Optimistic concurrency control raises an error only at the end of a unit of work, when data is written. Multiuser applications usually default to optimistic concurrency control and database connections with a read-committed isolation level. Additional isolation guarantees are obtained only when appropriate; for example, when a repeatable read is required. This approach guarantees the best performance and scalability. Understanding the optimistic strategy To understand optimistic concurrency control, imagine that two transactions read a particular object from the database, and both modify it. Thanks to the read-committed isolation level of the database connection, neither transaction will run into

any dirty reads. However, reads are still nonrepeatable, and updates may also be lost. This is a problem you ll face when you think about conversations, which are atomic transactions from the point of view of your users. Look at figure 10.6. Let s assume that two users select the same piece of data at the same time. The user in conversation A submits changes first, and the conversation ends with a successful commit of the second transaction. Some time later (maybe only a second), the user in conversation B submits changes. This second transaction also commits successfully. The changes made in conversation A have been lost, and (potentially worse) modifications of data committed in conversation B may have been based on stale information. You have three choices for how to deal with lost updates in these second transactions in the conversations:

<compiler name="msvc" /> <fileset dir="src/cpp/windows" includes="**/*.cpp"/> <includepath location="${generated.dir}" /> <sysincludepath location="${env.JAVA_HOME}/include" /> <sysincludepath location="${env.JAVA_HOME}/include/win32" />

Last commit wins Both transactions commit successfully, and the second commit overwrites the changes of the first. No error message is shown. First commit wins The transaction of conversation A is committed, and the user committing the transaction in conversation B gets an error message. The user must restart the conversation by retrieving fresh data and go through all steps of the conversation again with nonstale data. Merge conflicting updates The first modification is committed, and the transaction in conversation B aborts with an error message when it s committed. The user of the failed conversation B may however apply changes selectively, instead of going through all the work in the conversation again.

First comes the selection of the compiler itself; the default is always GNU gcc. We will cover compiler declaration and configuration more in section 17.5. The next element is a fileset declaration pulling in our source files. We have created Windows and Unix subdirectories under the source, to keep everything separate. In a complex project, you may have common source as well as platform- and compiler-specific files, making fileset inclusion more complex. Conditional patternsets are the key to managing this. The compiler also needs to know the location of include files in external directories. We use the <includepath> and <sysincludepath> elements to describe this. We list the javah-generated header file in an <includepath> element, and the Java JNI header files in two <sysincludepath> elements. We don t need to refer to Visual Studio s own header files, provided the INCLUDE environment variable is configured correctly.

If you don t enable optimistic concurrency control, and by default it isn t enabled, your application runs with a last commit wins strategy. In practice, this issue of lost updates is frustrating for application users, because they may see all their work lost without an error message.

Header files listed in the <sysincludepath> directory are not included in the dependency checks; they are assumed to never change. We do want dependency checking on the generated header file, which is why we point to that directory using <includepath>. Configuring a linker After compilation comes linking, which we specify with the linker element:
