Warehouse DB maintenance

Technote (FAQ)


What tasks should we have to perform in order to maintain our Datawarehouse DB on DB2 ?


The S&P agent only remove Data of tables without performing an allocation of the space released. Therefore a reorganisation of data in tables and indexes needs be performed.


A. we can schedule the reorg automatically as it is indicated in the url:


B. we can do it manually running the commands:

1. db2 connect to warehous user <user> using <password>

2. db2 reorgchk on table all (the output will tell us what tables are asking for a reorg)

then for each of these tables we are going to run:

3. db2 reorg table <schema>.<table_name>

4. db2 reorg indexes all for table <schema>.<table_name>

5. db2 runstats on table <table> with distribution and detailed indexes all db2 terminate
