I have hundreds of tables in my DB2.
Is there a way to get a list of them with a description of their content (the
procedure and the transaction they are related to)?

Thank you. Anna - Verona (Italy)

db2look can reproduce the ddl of all objects

Please, could you tell me what is db2look and what is a ddl?
I use QMF for Windows or TSO.
Thank you

ddl is all the statements you need to recreate the database and objects
db2look is a utility supplied with db2 to mimic a database
try : start - run - db2cmd
db2look -d dbname -e -l -x -o db2look.out
the file db2look.out will contain all statements (data definition language)
to recreat all objects in indicated database

Excuse me, but do I have to write -e -l -x -o?
Thank you

yes
-e mimic plain text objects
-l tablespaces
-o output file
-x grant statements

db2look is available on the DB2 for Linux, UNIX, and Windows client, and maybe works with DB2 for z/OS if you have a remote dcs client connection. It does not work directly in DB2 for z/OS from TSO. It will not show which plans/packages (programs) the tables are bound to, except that it "may" show SQL stored procedures DDL. I doubt that this is what you are looking for.

Many DB2 for z/OS shops have TSO applications (from IBM or 3rd party tools) that let you browse for information from the DB2 catalog. Contact your DBA about such tools.
