Question

Why do I have big '*.LRG' files under 'db2' directory, like:
$SCAPI_HOME/ db2/db2inst1/db2inst1/NODE0000/SCAPIDB/T0000004
rw------- 1 db2inst1 db2iadm1 422718734336 Aug 1 07:32 C0000000.LRG

Answer

We can apply the following 'DB2' commands to reduce table-space size:

db2 connect to SCAPIDB

db2 alter tablespace TSAA_LARGE reduce max;

db2 alter tablespace TSAA_HUGE reduce max;

db2 alter tablespace TSAA_SMALL reduce max;

db2 alter tablespace TSAA_RDF reduce max;

db2 terminate

 

-- these commands can be run against an active database.

-- they might take up to 20 minutes to take full effect.

-- the effect can have be small or large - depends on the churn/usage on the system
