DB2 Query to retrieve all table names for a given schema

DB2 LIST TABLES FOR SCHEMA <schema_name>

--for DB2/z
    select * from sysibm.systables
    where owner = 'SCHEMA'
    and name like '%CUR%'
    and type = 'T';

--for DB2/LUW
    select * from sysibm.systables
    where CREATOR = 'SCHEMA'
    and name like '%CUR%'
    and type = 'T';

This will give you all the tables with CUR in them in the SCHEMA schema.

See here for more details on the SYSIBM.SYSTABLES table. If you have a look at the navigation pane on the left, you can get all sorts of wonderful DB2 metatdata.

Note that this link is for the mainframe DB2/z. DB2/LUW (the Linux/UNIX/Windows one) has slightly different columns, as per the second query above.

You should examine the IBM docs for your specific variant if you're using neither of those.
