GOAL:
SHMMAX and SHMSEG Changes in Version 9.0B
FIX:
SUMMARY:
Changes made to Progress Version 9.0B
with regards to SHMMAX and SHMSEG. You might encounter error 1175 as
a result of these changes.
EXPLANATION:
Prior to 9.0B the maximum shared memory segment size (SHMMAX) we used
in the Progress RDBMS was 16,777,216 (16MB) for most UNIX Operating
Systems. The exception to this was NT, AIX, Sequent PTX and DG-UX
where it was 134,217,728 (128MB). The maximum number of shared memory
segments (SHMSEG) you could have was 116.
In 9.0B and later, these values have changed to the following:
Progress Total Shared
Port: SHMMAX SHMSEG Memory Accessed:
-------- ------------ ------ ----------------
32-bit 134,217,728 21 2.8 gig
(128MB)
64-bit 1,073,741,824 116 124 gig
(1GB)
NOTE: The total shared memory directly accessed is dependent on the OS
limitations.
