Hi Jim,

Have you set the access to the kernal memory file /dev/kmem on unix
equivalent...ingres must be able to read this file :

How You Create the System Administrator Account on UNIX
Only the system administrator (instance owner) can install Ingres,
therefore, you must create this account before installing the product.

Follow this process to create the system administrator account:

Log in to your system through the root account.
If you do not have access to this account, have the UNIX system
administrator complete this procedure or log in for you.

Set up an account with a login name of your choice. (The default is
"ingres.")
This account should have a user identification code (UID) greater than
100.

Add this user to the kmem group in the /etc/group file, as described in
your operating system documentation.
Make sure that /dev/kmem is in the kmem group and that its permissions
are set to "group read." For example:
%ls -lgL /dev/kmem

crw-r----- 1 sys 13, 1 Jun 19 09:05 /dev/kmem

Note: Check the Readme file for your operating system for any variation
in this procedure.

Subject: [Info-Ingres] Insufficient shared memory is available

Hello all,

I am attempting to install ingres 2006 r2 on redhat es linux
2.6.9-78.0.8.ELsmp. The install seems to go ok, but I keep getting
insufficient shared memory errors. I am a little confused though, as
the following is set in the kernel:

shmmax: 4294967295
shmall: 268435456

And then ingres complains when starting:

An attempt to allocate 33100768 bytes from the shared memory for use as
a log page buffer was rejected because the shared memory is exhausted.

It would seem to me that there is plenty of share memory available, am I
missing something?

Thanks,

Jim
