Sun N1 Service Provisioning System 5.2 Installation Guide

Operating System Configurations

To install and run the provisioning system, you must configure your systems as described in the following sections.

Solaris System Configuration Requirements

A Solaris system that is running the Master Server requires the following /etc/system settings.

Note –

If you are using the Solaris 9 or Solaris 10 OS, you cannot change the values for shmsys:shminfo_shmmin and shmsys:shminfo_shmseg. If you are using the Solaris 10 OS, you cannot change the values for shmsys:shminfo_shmmax, shmsys:shminfo_shmmni, semsys:seminfo_semmns, and semsys:seminfo_semvmx.

The default values for these settings are acceptable.

Table 2–2 Solaris /etc/system Settings

Variable 

Minimum Value 

shmsys:shminfo_shmmax

0x20000000 [536870912 in decimal (512Mb), but this number must be specified in hex for the Solaris 8 Operating System.]

shmsys:shminfo_shmmin

1 

shmsys:shminfo_shmmni

2 

shmsys:shminfo_shmseg

1 

semsys:seminfo_semmni

32 

semsys:seminfo_semmns

512 

semsys:seminfo_semmsl

17 

semsys:seminfo_semvmx

537 

For more instructions to change the /etc/system settings, see Solaris Tunable Parameters Reference Manual.

Solaris 10 Configuration Requirements

In the Solaris 10 environment, the /etc/system settings are replaced by resource controls in the context of the user who owns the installation. The following table defines the minimum values:

Table 2–3 Solaris 10 Resource Controls Settings

Variable 

Minimum Value 

project.max-shm-memory

512 

project.max-sem-ids

32 

process.max-sem-nsems

17 

ProcedureTo Determine If the Resource Controls Need to be Reset

Steps

  1. Determine the project ID.


    $ id -p

  2. Verify the current values of project.max-shm-memory, project.max-sem-ids, and process.max-sem-nsems assuming a project ID value of 1.


    # prctl -P -n project.max-shm-memory -i project 1
# prctl -P -n project.max-sem-ids -i project 1
# prctl -P -n process.max-sem-nsems -i process $$

  3. Set resource controls.

    If the current values do not meet the minimum settings required, you can use either the prctl command or the projmod command. Changes made with the prctl command are good only until system reboot. The projmod command should be used to make changes that persist across reboot.

    • Using the prctl command:


      # prctl -n project.max-shm-memory -v 536870912 -r -i project 1
# prctl -n project.max-sem-ids -v 32 -r -i project 1
# prctl -n process.max-sem-nsems -v 17 -r -i process $$

    • Using the projmod command:


      # projmod -a -K "project.max-shm-memory=(priv,512mb,deny)" default
# projmod -a -K "project.max-sem-ids=(priv,32,deny)" default
# projmod -a -K "process.max-sem-nsems=(priv,17,deny)" default

Linux System Configuration Requirements

The bc command must be in the user's path when you install the Sun N1 Service Provisioning System. Without the bc command, the installation exits and requests that bc be installed. Install the bc-1.06-5.rpm package or a later version of the package.

When you install the Sun N1 Service Provisioning System on an NFS mounted directory on a SUSE Linux 8 server and you want to use SSH or SSL for secure connections, configure the NFS client with nolocks or the NFS server to allow locks. If neither the NFS client nor the NFS server is configured properly, the Sun N1 Service Provisioning System application will not start.

The Linux Master Server installation program checks the following system parameters and exits with an error if the minimum values are not met.

Table 2–4 Linux Master Server System Settings (32–bit, 64–bit)

System Parameter 

Minimum Value 

shmall in /proc/sys/kernel/shmall

536870912 (512Mb) 

shmmax in /proc/sys/kernel/shmmax

536870912 (512Mb) 

Additionally, for the Linux 64–bit platform the semaphore settings should be changed in the /proc/sys/kernel/sem file to the following values:


4000  512000  512  4096

These numbers equate to the following four values:
