Hi!
I have installed IAS 9i under linux RH 7.2, SErver is a LH6000 with 4.5 GB RAM. We cann't access to Console administration is that problem of memory? this is the free command show.

total used free shared buffers cached
Mem: 4207 4201 5 307 229 2231
-/+ buffers/cache: 1741 2466
Swap: 2047 0 2047

I have performance problem too. can i reduce the cached memory?

Oracle made arrangements for enhancements to be put into the later versions of the Linux Kernel.

A good idea would be to use the red hat network and get the latest Kernel big memory version.

The console administration issue is probably due to configuration issues on the httpd server that ships with ias.

You swap is a little light based on my experience. In general for ias installation I set swap to 1.0 to 1.5 times physical memory.

`swapoff' the present swap area. Resize your swap partition using fdisk and `mkswap' it. Bring up the new swap area with `swapon'. Your friends here are the manpages for fdisk, mount and swapon.

creating a swap file
if you don't have free space to create new partition - then do the following:
1.mkdir -p /var/swap
2. dd if=/dev/zero of=/var/swap/swap.file bs=1024 count=250000 (to create aproximately 250 MB file)
3. mkswap /var/swap/swap.file
4.swapon /var/swap/swap.file

The above update speaks about, adding a file swap. If you have a partition (fdisk) or a volume (VxVM or LVM),
# mkswap
# swapon

Thanks,

Do i need to restart server?

I don't think you need to restart the server.

You should however to make sure the swap area is activated at boot time.

you don't need to restart your server.
You can use the "free" command to see how much memory you have.
For this configuration to load after you reboot your pc-you must add an entry to /etc/fstab file.Add something like this:
/var/swap/swap.file swap swap defaults 0 0
