Full Discussion: Intermittent "slowdowns" on Solaris 2.6
Special Forums Hardware Filesystems, Disks and Memory Intermittent "slowdowns" on Solaris 2.6 Post 26372 by RTM on Thursday 15th of August 2002 11:28:45 PM

Sorry, more questions!

The 'identical' machine - how many users does it have on it?

(back to the original server) Are you running NFS on it sharing out drives?

What does swap look like during normal times versus slow times?

Do the users on the normal server have the same paths as on the 'second' server? Do the two server reside on the same network?

Are there any backup processes running (both our Sybase and Oracle DBA run hourly backups - found that the Sybase one ran gzip across a NFS mount which was killing our server for about 3 minutes each hour - combination of the program running from a NFS mount, doing the compression, and the fact it was on the same drive as the data - top didn't show it except for once in a while - it was more guessing than knowing that it was the problem and we turned it off to every two hours during the normal work day )

Are /etc/system the same on both servers?

Do you have any 3rd party monitoring software (such as BMC Patrol or Landmark) that shows anything ?

Are you the only admin who can change things? Are you SURE no one added something - changed when things run -

install-solaris

install-solaris(1M)													       install-solaris(1M)

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
