When you upgrade
your DB2® server, it is a good
measure to run some tests on the new environment to verify that the DB2 server is working as expected.
These tests can consist of batch programs that you usually run against
the DB2 server or any programs
or scripts that you run for benchmarks.
If you have DB2 command scripts with SQL statements,
you can use the db2batch benchmark tool command
to execute the statements in these scripts, and gather performance
information details and statistics such as CPU time and elapsed time.
This tool can work in both a single partition database and in a multiple
partition database.
Before you begin
Ensure that you have the same authority level that is required
to run the SQL statements in your script.
Procedure
To verify that your DB2 server
upgrade was successful:
- Log on to the DB2 server
as a user with the same authority level that is required to run the
SQL statements in the script.
- Prepare a script with SQL statements that you frequently
run. If you installed the sample files, you can also run any of the
sample CLP scripts.
- Run your script using the db2batch command. The following example shows you how to run this tool with
the testdata.db2 sample script:
cd samplefile-dir-clp
db2batch -d sample -f testdata.db2 -o r 0 p 3
where samplefile-dir-clp is DB2DIR/samples/clp on Linux and UNIX and DB2DIR\samples\clp on Windows, DB2DIR represents
the location for your DB2 Version 10.1 copy, sample is the database name, and the option -o
r 0 p3 indicates to print 0 fetched rows to the output
and to report elapsed time, CPU time, and summary of monitoring information
for each statement in the testdata.db2 script.
The
following text is an extract of the summary table output generated
by the command in the previous example:
