memory heap dump

Dumps

Memory Heaps

To dump the top-level heap in a memory area

    ALTER SESSION SET EVENTS
    'immediate trace name heapdump level level';

Levels are

Level Description 1 PGA summary 2 SGA summary 4 UGA summary 8 Callheap (Current) 16 Callheap (User) 32 Large pool 64 Streams pool 128 Java pool 1025 PGA with contents 2050 SGA with contents 4100 UGA with contents 8200 Callheap with contents (Current) 16400 Callheap with contents (User) 32800 Large pool with contents 65600 Streams pool with contents 131200 Java pool with contents

Levels are correct to Oracle 10.2.0.1

The levels can be combined. For example a level 3 dump will contain both the PGA and SGA
