RE: identifying shared memory segments

From: Trassens, Christian <CTrassens_at_uni2.es>

sysresv is an utility that comes on 8i and works on each Unix env. However, you can issue oradebug ipc from svrmgrl or from sqlplus since 8i on every env.. Before 8 oradebug ipc shows you semaphores sets and shared memory segments on the screen. From 8 it writes the info in a trace.

F.e.:
On 7.X.:

SVRMGR> oradebug ipc
-------------- Shared memory --------------

Seg Id     Address   Size
61009      ca7ec000  195010560

Total: # of segments = 1, size = 195010560
-------------- Semaphores ----------------
Total number of semaphores = 300
Number of semaphores per set = 300
Number of semaphore sets = 1
Semaphore identifiers:
 6762152

On 8.1.X:

Conectado a:
Oracle8i Enterprise Edition Release 8.1.6.2.0 - Production With the Partitioning option
JServer Release 8.1.6.2.0 - Production

SQL> oradebug ipc
Information written to trace file.
