What is SQLTXPLAIN (SQLT)?

SQLTXPLAIN, also known as SQLT, is a tool provided by Oracle Server Technologies Center of Expertise - ST CoE. SQLT inputs one SQL statement and outputs a set of diagnostics files. These files are commonly used to diagnose SQL statements performing poorly. SQLT connects to the database and collects execution plans, Cost-based Optimizer CBO statistics, schema objects metadata, performance statistics, configuration parameters, and similar elements that influence the performance of the SQL being analyzed.

Pro-Active Problem Avoidance and Diagnostic Collection

Although some problems may be unforeseen, in many cases problems may be avoidable if signs are detected early enough. Additionally, if an issue does occur, it is no use collecting information about that issue after the event. SQLTXPLAIN is one of the tools that support recommend for collecting such diagnostics.
