Dear people,
After installing ORACLE 8.0.4 on the DEC with Digital Unix version 4.0D I
get the error message 'ORA 27123: unable to attach to shared memory
segment'.
I believe this has to due with attributes in one of the subsystems of the
kernel.
In the past I have modified the file '/etc/sysconfigtab' for tuning the
dynamic kernel with the following attributes:
ipc:
shm-min = 1
shm-max = 8388608
shm-mni = 100
shm-seg = 10
shm-all = 240
num-of-sems = 60
sem-map = 1026
sem-mni = 1024
sem-mns = 1024
sem-mnu = 1024
sem-ume = 10
msg-max = 4096
msg-mnb = 8192
msg-mni = 320
msg-tql = 320
Also I have created a new kernel by modifying the file /sys/conf/DEC, I
have added the following attributes:
dfldsiz 134217728
#maxdsiz 1073741824
dflssiz 2097152
#maxssiz 33554432
shmmin 1
shmmax 8388608
shmmni 100
shmseg 10
semmni 1024
semmns 1024
semume 10
maxdsiz 52428800
maxssiz 52428800
During boot of the system the following errors/messages appears:
attribute shm_all not in subsystem ipc
attribute sem_map not in subsystem ipc
attribute sem_mns not in subsystem ipc
attribute sem_mnu not in subsystem ipc
This modofications have I done in the past on version Digital Unix version
4.0B and Then I did not get these messages.
Can you tell me what to do to configure and tuning the (shared) memory to
let the existing applications and ORACLE run without problems?
Thanks in advange,
