Full Discussion: Intermittent "slowdowns" on Solaris 2.6

More information would be required - and even then it's hard to completely diagnose your problem.

1. What application(s) are running on the server?
2. How are the filesystems laid out?
3. How much memory (physical) in the server?
4. How much swap space?
5. What (if any) disk management software is being used?
6. Do you have top installed? What does it show as the top processes during the 'problem'?
7. Has the problem always occurred?
8. What changed recently - more users, more data, more cron jobs, more applications, ....


It comes down to knowing your system - something that may be hard to do if you never looked before. If you don't know how it ran before, you may not know what could have caused the change. Another thing - is this temporary slowdown seen as a problem to the users? If they don't complain, don't fix it. Just start keeping history of how it runs. Then when they do complain, you can show how it's out-grown the server in use.

Remember, adding memory can solve one problem and cause another - same with adding cpu and disk space. Rearranging how your data is laid out may help without buying anything.

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.

       See attributes(5) for descriptions of the following attributes:
