US Patent 7886281 System and methods for cross-tier transaction tracing

The disclosure is directed to a method of tracing processing of software instructions associated with a transaction. The method includes writing an access data stream addressed to a receiving application on a remote application server and writing a transaction identifier to the end of the access data stream. The receiving application is configured to read the access data stream and the transaction identifier when an instrumented version of the receiving application is implemented on the remote application server.
