The Transaction Manager controls transactions and commit operations and manages database recovery.
Essbase commits data automatically. Commits are triggered by transactions that modify data—data loading, calculating, restructuring, and spreadsheet lock and send operations.
How Essbase commits data depends on whether the transaction isolation level is set to committed or uncommitted access (the default). See Committed Access and Uncommitted Access.
The Transaction Manager maintains a transaction control table, dbname.tct, to track transactions.
For information about commit operations and recovery, see Recovering from a Crashed Database.
