OO Support Tip: Run history is not sequential in 9.x
This behavior is expected.
OO uses sequences to generate the next number in a list. Sequences do not guarantee they are in sequential order.
In Oracle for example the OO sequence is named hibernate_sequence.
To find the name of sequences in Oracle the following sql command can be used:
select sequence_name from user_sequences;
To Find the current value of a sequence use the following sql command:
select hibernate_sequence.currval from run_history;
