A minimum of two accounts are needed to install and run IEPM-BW. The account for running IEPM-BW
should be named 'iepm', and the recommended home directory is '/home/iepm'. An account with root privileges
for the installer/administrator is also required.
It is recommended that the operating system be the latest stable version of RedHat.
The following /etc/sysctl.conf parameters are recommended for optimum performance on both the
Monitoring host and the target host:
/proc/sys/net/core/wmem_max = 20971520
/proc/sys/net/core/rmem_max = 20971520
/proc/sys/net/core/rmem_default = 65536
/proc/sys/net/core/wmem_default = 65536
/proc/sys/net/ipv4/tcp_rmem = 4096 87380 20971520
/proc/sys/net/ipv4/tcp_wmem = 4096 65536 20971520

To allow for running OWAMP, the monitoring and target hosts should be configured with 4 NTP servers.
The OWAMP documentation discusses how to setup NTP.
A web server must be installed and running on the monitoring host machine. The document root should be set to '/var/www'.
An account 'iepm' must be allocated on both target and monitoring hosts. The source code will be put into ~iepm/v3src.
The latest version of JAVA must be installed on the monitoring host.
Gnuplot 3.7 Patchlevel 3 (or higher...4,0 is ok) 4.0 is required and must be installed on the monitoring host machine
MySQL is required on the monitoring host. We are currently installing "mysql MySQL Ver 14.12 Distrib 5.0.18".
I recommend installing the latest production version of MySQL to ensure upward compatibility.
Important notes for later reference:
- To start they mysql daemon, use mysqld_safe&
- To set the root password after installation use: mysqladmin -u root password "new password"
- To shut mysql down, use mysqladmin -u root -p shutdown
