I hv 24 tables in the schema, and needs to use DML and select operations on these tables for 24 tables to check the db performance testing. Can someone give the idea how can I generate the load on db??

If you needs any details then let me know.

I have gone through many testing tools like SLOB, SwingBench, and HammerDb etc but there are restriction of tables means these tool can generate upto max 9 tables in a schema. if you have the idea of testing tool that can generate the load testing for higher numbers. to come up over to 8-9 tables I have created 24 static table so now I want to load on those data tables by script/tools. pls let me know for details. thanks

Yes, I need detail! Specifically, what is the purpose of this load testing? If it is to compare performance of the database and hardware then the TPC benchmarks should be fine; if it is some application that you have written, then you may have to write your own tool.

Simple shell script(s) will do the trick like a master script which will execute a client one (syntax may change depending on your shell):
# parameter = number of clients
i=1
while [ $i -le $1 ];
do
  client.sh &
  i=`expr $i + 1`
done
client.sh:
sqlplus usr/psw <<EOF
  <....the statements you want...>
EOF
Now client.sh may accept parameters like:
- type of the client: depending on it the statements are different
- think time: between each statements you wait for this time to simulate an interactive client
- a number of times the statements hav to be executed before leaving
...
Instead of sqlplus, this may a SQL*Loader or imp/impdp call...

John,

Yes, It is to compare performance of the database and hardware. I have already tried to use TPC-C/TPC-H benchmark but these benchmark generates the schema only for 8 to 9 tables. Client here suggest us that 9 tables is not good enough to check, it must me 20-50 table set to check the performance test. I have here now 24 table's schema with dummy data set. is there any testing tool there we can enter/set the numbers of table more than 9.

thanks,

You need to educate your client. The TPC benchmarks are the industry standard, in what way does he think they are inadequate for him when they are good enough for the rest of the world? There is no reason why the number of tables used by the benchmark is of any significance.

Of course, if he has the budget you can charge him to develop his own benchmark that hits a thousand tables Smile

My question is based on oracle load testing and needs to know the process of load testing with lot of tables(dummy datasets). Bcz benchmark tools as I hv used test only on max 9 tables. Client need more than 20(min).

John, Agreed with your comment. But Hereafter I have one more question that What is the workload percentage of DML/Select operations in hammerdb TPC-H???
As calling circle (Oracle swingbench) benchmark percentage is like • Select 83% • Insert 7% • Update 10% • Delete 0%

Come on, man. How would I know? If you can't work it out by looking at the code and the docs yourself, ask the appropriate people. Not me.

I wanted to provide you a complete set of scripts to achieve your needs but as you have not the slightness correctness to answer me and showed the behavior of a lazy contemptible person I leave this topic and won't come back to any of your future ones.
