| Local Fix: |
As a temporary workaround, follow the following steps:
1. Open partial populated db2look output and navigate to the
very end.
2. The last table for which column stats are updated is the one
having NULL values in its statistics.
3. Run runstats command on that specific table to populate the
statistics.
ex:
db2 runstats on table <tabschema>.<tablename>
NOTE: Any runstats option can be used.
4. Run db2look again.
Note: Step 3 and 4 maybe repeated as there may be other tables
having similar issue. |
