If you’re interested in creating a TPC-H schema for testing purposes, then the following scripts may be of use to you:

Unix Scripts:
Multi Load TPCH
Load TPCH Stream

SQL*Loader Control files:
REGION Table
NATION Table
SUPPLIER Table
CUSTOMER Table
PART Table
PARTSUPP Table
ORDERS Table
LINEITEM Table

You may wish to read and check them before you use them – they’re not exactly rocket science but they seem to do the job.

I have all the files in the same directory for simplicity sake.

I then use them to create a scale factor 1 target TPC-H schema using the following calls:

# “l” loads the REGION and NATION tables
On completion of the registration cheap online levitra process a mail will be sent to you confirming your request. The plant’s ability to increase Facts about viagra samples sale viagra sexual desire and improve sexual function. One medicine that has stood out in the market, and these equipment are utilized by skilled spebuy generic cialis http://davidfraymusic.com/events/meyerson-hall/ts in different fields. Thus, next time do buy whenever you are out for grocery purchase female viagra davidfraymusic.com shopping. ./multi_load_tpch.sh 1 l “tpch/tpch@test” 1

# “s” loads the SUPPLIER table
./multi_load_tpch.sh 1 s “tpch/tpch@test” 10

# “c” loads the CUSTOMER table
./multi_load_tpch.sh 1 c “tpch/tpch@test” 10

# “p” loads the PART and PARTSUPP tables
./multi_load_tpch.sh 1 p “tpch/tpch@test” 10

# “o” loads the ORDERS and LINEITEM tables
./multi_load_tpch.sh 1 o “tpch/tpch@test” 10

Obviously, you need to change the connection string to match your environment.

Caveats:

1. Obviously, they are supplied as is – use at your own discretion and risk.
2. You need to have created the target schema tables and made sure they are empty as the SQL*Loader control files use APPEND.
3. Bear in mind that choosing too high a number of parallel streams (the last parameter in the calls) will overload your machine so try and balance it against the available system resources.
