| SPR # XJXJ6RW8VF | Fixed in 7.0.2 FP1; 7.0.3 release |  |
Product Area: Server Technical Area: Server Platform: AIX
SPR# XJXJ6RW8VF - The Notes.ini variable AixLimitShmSegments, is to be used in place of the Notes.ini variable ConstrainedSHMSizeMB to ensure entire segments are specified for shared memory. The lower limit is 3 and the current upper limit is 10. The maximum number of shared memory segments when using the AIX Large Memory Model is 8. The maximum number of shared memory segments when using the AIX Very Large Memory Model is 10. Future releases of Domino may allow for a maximum of 11 shared memory segments.
Technote Number: 1253505
Problem:
This issue has been fixed in Domino 7.0.2 Fix Pack 1 (FP1).
Excerpt from the Lotus Domino Release 7.0.2 FP1 fix list (available at
http://www.ibm.com/developerworks/lotus):
SPR# XJXJ6RW8VF - The Notes.ini variable AixLimitShmSegments, is to be used in
place of the Notes.ini variable ConstrainedSHMSizeMB to ensure entire segments
are specified for shared memory. The lower limit is 3 and the current upper
limit is 10. The maximum number of shared memory segments when using the AIX
Large Memory Model is 8. The maximum number of shared memory segments when
using the AIX Very Large Memory Model is 10. Future releases of Domino may
allow for a maximum of 11 shared memory segments.
Refer to the Upgrade Central site for details on upgrading Notes/Domino.
By setting AIX_LIMIT_SHM_SEGMENTS, the Domino instance will have access to
shared memory on a whole segment basis. One memory segment on AIX has the
maximum value of 256 Meg.
The lower segment limit is 3 and the current upper segment limit is 10 for
AIX_LIMIT_SHM_SEGMENTS.
To have access to the full 10 segments of shared memory, for use with
AIX_LIMIT_SHM_SEGMENTS, it is necessary to set AIX_VERY_LARGE_MM=1.
AIX_VERY_LARGE_MM requires Domino 7.0.2, AIX 5L version 5.2 or later, running
the AIX 64 bit kernel.
Without setting AIX_VERY_LARGE_MM, the upper limit for AIX_LIMIT_SHM_SEGMENTS
is 8.
An example setting of AIX_LIMIT_SHM_SEGMENTS=5 would provide 5 256 Meg segments
or 1280 Meg of shared memory.
As with ConstrainedSHMSizeMB, setting AIX_LIMIT_SHM_SEGMENTS, too high will
result in limiting the number of segments for process memory. More >
