I beg to differ. Normally, a wrong entry in the semaphore in the /etc/system file will cause the DB to be unable to start up.

If the error you see happens a couple of days after restarting the DB, most likely it is due to fragmentation shared pool.

These are the things you can try in order:
1) Check for SQL that are not using binding variable, get your developers to change them to binding variable. This will reduce the number of distinct SQLs required to be cached in the shared_pool.

2) Increase the shared_pool and reduce the shared_pool_reserved size. This will allow more distinct SQLs to be cached in shared_pool and at the same time, reduce the usage of shared_pool_reserved. (This will help if the fragmented shared pool you are facing is at the shared_pool_reserved)

3) Check Oracle metalink for bugs related to this oracle error. I do know that Oracle 9i has a bug related to this, not too sure on Oracle 8i.

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.

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