Hi There,

Our admin guy is not here so how can i check if the kernel table ninode is over threshold 80%?

Thanks

An easy way is through glance. You can issue the command "glance" to access the text based version, or "gpm" to acces the graphical version. Once there you can look at the appropriate tables to determine usages.

The ninode parameter is for HFS file systems, most, if not all, database filesystems are on vxfs, so the ninode parametere does not apply.

hello,

Use "glance" and move to system table info using key "T" and you can find the usage of ninode parm. or use "sar -v 2 5"

Cheers

If you look at ninode in glance under System Tables, you can do a h for help, highlight current screen metrics and inode cache to read information about the inode table.

ninode applies only to hfs file systems. How many files on your system are hfs?? (only /stand would be)

you can monitor the real time usage of it as follows.

sar -v 2 10
glance -T

The simple answer is: sar -v 1

However, ninode will always be 100% within a few days. This is because it is a cache and cannot be measured as to how many entries are reusable. For a 'normal' 11.00 or 11.11 system, ninode should be about 4k to 8k and larger ONLY if you have a massively large HFS filesystems that are very busy with lots of open files.

To see exactly which filesystems are HFS, type the command:

bdf -t hfs

If all you see is /stand, and ninode is about 4k-8k, you're fine. If ninode ever overflows, it will be logged in syslog with the message: inode: table is full. Otherwise, don't worry about it.
