about create index online

HI,

Just wondering is that OK to create index online ( without down the
application servers)..

it's OLTP 24*7 production environment..

Is that OK to create index on one table online ? the table size is
less than 1GB.

there is insert and update on the table from application.

very appreciated for any suggestion on it.

It's not so much the size (1GB) as the number of rows as the the table
as to be scanned to pick up the keys then sort them to generate this
index.
This can be done online if you are at DB2 V8.2 and up. The CREATE
INDEX command will run while providing full access to the data for
other appls.
Regards, Pierre.

SQL Server 7/2000: We have reasonably large tables (3,000,000 rows) that we need to add some indexes for. In a test, it took over 12 hours to CREATE a new INDEX against this table. One of us suggested that we create a temp table with the new index and copy the data from the old table into the new one, then rename it. I understand this took 15 minutes. Why the heck would it be faster to move the data and build multiple indexes...

Greetings, I have a 23GB data table upon which I am building a primary key of three columns. The data is mounted in a 137GB device and pg_xlog is mounted on a separate 3.5GB device. I have configured 24 checkpoint segments, which I expect gives me a worst-case usage in pg_xlog of 384MB. Unfortunately, during the CREATE INDEX, pg_xlog becomes full!
