Home -> Community -> Mailing Lists -> Oracle-L -> RE: strange behaviour of sequence
Probably you use the (default) 'cache 20' and shut down the database between the 'BREAD4' and 'BREAD21' insert.
Or you use OPS/RAC, which cause each instance to cache this '20' numbers.
This can be avoided by using the 'nocache' option, but then you serialize access to the sequence number, which can be a very bad idea from the performance perspective..

Mario

Guys,
one of my developers is using sequence to auto-increment the value of a column while inserting.
he has created a sequence like this.
SQL > create sequence testseq start with 1;
and then uses a INSERT statement as below in a JSP.
insert into testtab values ('BREAD'||testseq.nextval);
after some inserts .....when he does SELECT from TESTTAB...he
finds
the values as :
BREAD1
BREAD2
BREAD3
BREAD4
BREAD21
BREAD22
it should increment by 1.but it is not so ?
any hint/clue ????
Regards,
Jp.
