Except for end of first paragraph, copied from DB6 613

What causes this issue?

The database heap is a global area the database uses for memory areas
it administers itself, such as the:
Log buffer
Catalog cache
Control structures for the buffer pool
Instead of monitoring the upper limits, the system monitors here the
current database heap fill level.

System Response

If the database heap is full, transactions may terminated.

How to fix this error?

If there is an error, increase the size of the database heap using:
<LB>UPDATE DB CFG USING DBHEAP <value></>
Increasing this value increases the use of virtual memory, which
increases paging if there is not enough main memory available.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
