To find out the current size of the APP_CTL_HEAP_SZ value
, run:
db2 get db cfg for <databasename>
To increase the size of the APP_CTL_HEAP_SZ value, run:
db2 update db cfg for <databasename> using APP_CTL_HEAP_SZ
512
The following problem is encountered when the APP_CTL_HEAP_SZ
value is set at 128 in a V3.5 configuration.
In a V3.5.7 single node configuration, after creating 17 application
servers, the next start of an administration server fails with the
following exception:

This problem is resolved by increasing the administrative repository
database APP_CTL_HEAP_SZ to 512 in DB2.
