Detect Ingres Startup Problems on System Reboot (UNIX)
To detect Ingres startup problems on system reboot on UNIX, follow these steps:
1. The most common cause of startup failure following a reboot is failure to include the startup command ingstart in the boot script for your machine. (The boot file is vendor-specific but can be named “/etc/rc” or “etc/rc.local”.) This file contains the commands that are to be executed immediately after a reboot.
Make sure that the following line appears in the boot script:
su userid -c "ii_system/ingres/utility/ingstart ii_system" /dev/console
where:
userid refers to the user that owns the installation
ii_system refers to the value of II_SYSTEM for your installation.
2. Make sure that /dev/kmem is readable to the user that owns the installation. If this is a security problem for your machine, you can add this user as a member of /dev/kmem’s group and make the /dev/kmem group readable.
Issue the following command at the operating system prompt:
chmod g+w /dev/kmem
The user that owns the installation must be able to read /dev/kmem or the kernel resource checks in ingstart fails.
