If so, take a look how that user is setuped, especially projects. Solaris uses projects to impose various limits to users projects -l

What is your SGA ?
Are you running your database as a user ? (oracle?)
Are you using zfs filesystems for your database or ASM ?

Zones also have a limit system regarding memory and cpu which is defined in zone configuration file.

This is fairly well documented on oracle site regarding setup of solaris OS for oracle database (global and non-global zones).
Numbers in that documentation are subject to your environment needs.

For instance, in documentation parameter project.max-shm-memory is
4294967295 which is equivalent to 4 GB. This parameter should probably be increased in real life scenario to much higher value (again, depending on your workload, but looks like the errors are coming from there...)

As you might notice, me, as well as others, are guessing
That is not nice from your side, and time consuming from ours.

Hope that clears things out

Hi There is no project is created in server.

Code:

and there is no cpu/memory cpping implemented from zone level.

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:
