This section describes the system files modified by installation of Sun Management Center, and provides an overview of operating system patches.
The values listed in the /etc/system file are the default values for Sun Management Center system parameters. The shmmax value is computed based on the available RAM on the machine.
The Sun Management Center software installation checks whether the limits in the /etc/system file are sufficient for the services layer to perform as expected. For example, the following entries are added to the /etc/system file if the entries are absent. If the values present are inadequate, the values are updated accordingly.
**************************************************** * This file has been modified by Sun MC 3.6.1 setup. * * DO NOT REMOVE THESE TWO COMMENT LINES. * **************************************************** set shmsys:shminfo_shmmax=201326592 set shmsys:shminfo_shmmin=1 set shmsys:shminfo_shmmni=100 set shmsys:shminfo_shmseg=10 set semsys:seminfo_semmni=100 set semsys:seminfo_semmsl=115 set semsys:seminfo_semmns=200 set semsys:seminfo_semopm=100 set semsys:seminfo_semvmx=32767 |
If any of the /etc/system entries are changed by the Sun Management Center software installation, then the system must be rebooted before proceeding further. After the system has rebooted, you must rerun the setup process using either es-setup or es-guisetup.
If /etc/system was changed by a previous installation of the Sun Management Center software, a system reboot is not necessary.
The Sun Management Center software installation program adds the groups esadm, esdomadm, and esops to the local /etc/group file on the machine. A group entry is created for the database group smcorag in /etc/group on the machine where the Sun Management Center server is installed.
The user specified as the administrator during Sun Management Center setup is added to the esadm and esdomadm groups. For example, if the root user account is specified as the Sun Management Center administrator, the installation program appends the following lines to /etc/group:
smcorag::101011: esadm::1000:root esdomadm::1001:root esops::1002:
The Sun Management Center software installation adds the user smcorau to the /etc/passwd file. The smcorau user account is needed to run the database on the Sun Management Center server layer.
The /var/opt/SUNWsymon/cfg/esusers file is used to define authorized Sun Management Center users. For further information, see Users, Groups, and Roles Overview.
