Create index filled up transaction log

yongsing

I tried to create an index on a column of a table. It failed because
the creation caused the transaction log to be full. What can I do?
Should I export out the data in the table, then recreate the table
with the index, and finally import back the data?

Thanks in advance.

Why not increase the number and size of the log files?

clean the log (it's better to enlarge it)
and then rebuild the index (or maybe recreate the index)

You can increase the number and/or the size of your logs. For future
references, you may want to look at creating a table with the 'NOT LOGGED
INITIALLY' feature. When adding a new index, the table can be altered to
activate the above feature so that logging will not occur. Look at the
documentation for more details.

The easiest way is to use the Control Center. Right click on the database
(sample, etc) and select Configure...

You will see a tab there for "Logs." Increase the file size, number of
primary logs, and number of secondary logs. When you click on the parameter
there are hints on the lower right to assist you. The default values are
extremely low and need to be increased significantly for any large
production database.

Note that this is for Version 7 Control Center, version 8 Control Center is
slightly different, but same concept.

To change the parms using the command line, see chapter called Configuring
DB2 in the Administration Guide: Performance. The command line format is:
db2 connect to <dbname>
db2 update db cfg using <parameter-name> <parameter-value>
db2 connect reset

CREATE INDEX on large table

by: dfurtney | last post by:

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...

How to create non-unique index with DDL?

by: deko | last post by:

I'd like to use DDL (Data Definition Language) rather than VBA code to create a new table. The below DDL statement creates the table very nicely: CREATE TABLE tblTx03 (Subject Text (100), Entity_ID Long, TxDate Date, Tx_ID AutoIncrement Constraint PrimaryKey PRIMARY KEY); The problem is I want a non-unique index on TxDate - can this be done in the same statement? Or do I need to run a separate statement to add the non-unique index?

pg_xlog becomes extremely large during CREATE INDEX

by: Jeffrey W. Baker | last post by:

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!

type-2 index causing performance hit

by: bernhard.willems | last post by:

We are using DB2 UDB version 8.1 fp7 & fp9 on AIX 5.2. On our databases we do massive inserts and deletes (millions of rows). The performance is dramatically reduced because of pseudo deleted keys. In a 10 minutes it goes from 18000 transaction per minute to 9000 and lower. When an index reorg with CLEANUP ONLY PAGES is executed, the number of transactions climbs again. But a few minutes later it drops again to 9000. We have to run the...

Index and Null values

by: john | last post by:

Last week I posted about making a unique index on multiple fields to prevent importing identical records twice. I still have trouble with the nulls in the index. The only way that I can make it work is to make all the index' fields required fields and set the allow nulls setting to false. But then every field in the index should always have some kind of value, and I have to put a default value like "0" in them or "empty". Is this indeed the...
