Dear DBA Gurus,
Can you tell me how to prevent oracle
Hi Ranganath,
There are several situation for oracle to commit.
one of them of course you type 'commit;' manually
others can be :
when checkpoint occur
when switch redo log occur
when LRU function need to find space in your SGA
when shutdown normal (am I wrong ?, Oracle rollback or
set autocommit off (in sqlplus)
and i'm not sure but cant you set this to be the default to happen in some
glogin.sql file ?

Ranganath,
AFAIK, this can't be done. A normal exit has an
implied commit. Perhaps someone else can suggest a
way to do this programmatically.

Dear DBA
Sinardy,
I am afraid that you are under a number of misconceptions, and confusing writing to
disk and commiting. The former is something physical, and the later more logical,
althought it is also accompanied by a physical write.
Whenever a disk flush occurs, the 'state' of your transaction
Hi,
If you set autocommit off it will rollback any uncommitted transactions by
default when you exit SQL*Plus.

Can you tell me how to prevent oracle from
committing a transaction unless unless
I explicitly commit it.
To do what you are asking, exit sql*plus with the command:
exit rollback
This will exit you from sql*plus and it will prevent Oracle from committing
a transaction unless you have
Hi DBA Gurus,

Wow, you're right.
Let this be a warning to you all; this is what happens to your brain when you
mess with DB2. Just say no kids.

Hi Mike,
I was also thinking so. But it doesn't do so. Setting autocommit
off will
implicitly commit all your transactions
Keep in mind that if at any point you issue any DDL command, a commit is
automatically performed. For example, if you open a SQL*Plus session,
insert a few records, then do an alter table ..., those records will be
committed.
Just a thought...

Wait a minute here.
Why would oracle do a commit on your transaction
just because it needs to do a checkpoint, logfile switch, or shutdown?
What if errors occur during validation?
Do you think Oracle will commit the data anyways?

Commit will take place after any DDL statement. Besides that, Oracle
Complete Reference by George Koch and Kevin Loney states that commit will
occur after you execute the following commands: exit, quit, and even
connect.
If you are worried about unmanaged commits after the sudden instance crash
I did not try it but what if we have a trigger on logoff which will raise
application error.

No Oracle doesn't do commits for checkpoint, log switch or shutdown normal.
It will only commit data explicitliy (using the commit command) or implicitly (DDL).
SQL*PLUS by default auto commits for you if you just exit after doing some DML.
But you can turn that off.
