ISSUE: 3952
|
|
TITLE: TRACE: add statistics of actions that were after transaction finished
|
|
DESCRIPTION:
|
|
Three tables are created: permanent, GTT with on commit PRESERVE rows and on commit DELETE rows.
|
|
|
|
Trace config is created with *prohibition* of any activity related to security<N>.fdb
|
|
but allow to log transactions-related events (commits and rollbacks) for working database.
|
|
Trace is started before furthe actions.
|
|
|
|
Then we launch ISQL and apply two DML for each of these tables:
|
|
1) insert row + commit;
|
|
2) insert row + rollback.
|
|
|
|
Finally (after ISQL will finish), we stop trace and parse its log.
|
|
For *each* table TWO lines with performance statristics must exist: both for COMMIT and ROLLBACK events.
