Use sqlprofile to optimize slow SQL statements in goldengate and SQL statements
In HP unix, a process is monitored to occupy a high cpu. Later, it was found that the statement execution plan in gg had a problem, resulting in a high cpu. Since the statements in gg cannot be changed, how can we change the execution plan of statements that cannot be changed? sqlprofile can be used here for optimization. [Szggs
SQL Profile provides other information except system statistics and object (table and index) statistics for an SQL statement, such as the running environment and more accurate statistics, to help the optimizer select a more suitable execution plan for SQL statements.SQL Profiles can be said to be the evolution of Outlines. The functions that Outlines can implemen
