Gateserver OS Configuration

The actual amount of hard disk space can vary slightly from one disk to another. Be sure that you use all the available space on the drive taking care not to go below the levels outlined in the file system minimums column.

The /home2 file system should have a capacity of at least 800 MB. In addition, the /tmp file system should be created as a tmpfs file system with 100MB capacity minimum. Larger /tmp capacity may be necessary if any of your Classes of Service (COS) permits many subscribers to receive large (> 3 minutes) voice messages.

You may have to borrow from the /home2 file system to accommodate the other minimums, but place as much available space as possible in the /home2 file system.

Note Use showrev -p to determine which Solaris patches are currently installed.

Solaris tuning

Note Prior to making the following changes, ensure that a copy of the original /etc/system file is preserved.

The following settings should be present in the /etc/system file.

set pt_cnt=1024
set shmsys:shminfo_shmmax=67108864
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmseg=32
set dosynctodr=0

Machine Naming Requirements for DAP

You must use names instead of IP addresses when referring to hosts on the Gateserver. It is recommended to use /etc/hosts as your primary means of name resolution and DNS as your secondary means of name resolution. Use of NIS is discouraged. Take care to keep /etc/hosts consistent on all hosts. If you use DNS, be sure to:

Configure your Domain Name System (DNS) servers to include the names of all hosts.
Configure mail exchange MX records for the e-mail domains honored by your SMTP servers.
Configure your hosts to use at least two DNS servers (primary and secondary).

Setup sendmail Daemon

You should setup the sendmail Daemon. This is used as a secondary SMTP MTA if the primary fails.

Configuring RPC Service Names (Recommended)

Note You cannot perform this procedure until the ACB has produced a $PARMLIB/parms/BASE/ObjectInfo.APP.<hostname> file. Thus you may have to return to this step later. Such a file is created by running the ACB on a host. This can be any host because the output in this file has to be consistent for all hosts.

You can add one line to the /etc/rpc file for the ACB. This configures the ACB name so it will be visible in the output of the rpcinfo command.

Note the following requirements when editing the /etc/rpc file:

This assumes /etc/nsswitch.conf contains files for rpc.
Edit the file as superuser.
Gather name (column 2) and RPC number (column 1) information for APP from one of your $PARMLIB/parms/BASE/ObjectInfo.APP.<hostname> files.
Add the name, prefixed with "DAP_", and number to the end of the file. The format is as follows:

DAP_ACB <RPC-number>

Ignore the line containing TNT.

Figure 4-1: Example /etc/rpc addition

Note It is important that the RPC number correspondence be consistent on each host. Files that configure or display RPC number are /etc/rpc and $PARMLIB/parms/BASE/ObjectInfo.<object>.<hostname>. Be sure not to create any inconsistencies between these files.
