You might try reading the DB2 dictionary tables with explicit SQL passthrough. The code would look something like this (at the minimum, the items in CAPS will need to be modified):
proc sql;
connect to db2(database=MYDB);
select * from connection to db2
(select tabschema
, tabname
, create_time
, stats_time
from syscat.tables
where tabschema = 'SCHEMA_NAME'
order by typename);
disconnect from db2;
quit;
