Concurrency Control Through Isolation and Locking

TimesTen transactions support ANSI Serializable and ANSI Read Committed levels of isolation.

ANSI Serializable isolation is the most stringent transaction isolation level. ANSI Read Committed allows greater concurrency. Read Committed is the default and is an appropriate isolation level for most applications.

The following sections describe transaction isolation and locking levels:
