3.1.5 Files that are executed during system startup

This section identifies, for each OS, the files that are executed during system startup and how the native agent is started.

For details about the native agent processes required for SNMP Agent, see Appendix D. List of Prerequisite Patches and Processes (Services) for SNMP Agent.

• In HP-UX (IPF)

  The /opt/CM2/ESA/bin/snmpstart command is executed from /sbin/rc2.d/S560esa. If the native agent process is not running, the SNMP Agent process and native agent process are started.

  If the native agent process is running, the SNMP Agent process is started, and the native agent process is restarted.

• In Solaris

  /etc/rc2.d/S97esa is executed.

  In Solaris 10, if the native agent (snmpd process) is not running, the SNMP Agent process and the native agent (snmpd process) are started.

  If the native agent is running, only the SNMP Agent process is started.

  In Solaris 11, only the SNMP Agent process is started, regardless of whether the native agent (snmpd process) is running.

  Starting of the native agent is controlled on the OS side.

• In AIX

  The /usr/CM2/ESA/bin/snmpstart command is executed with no arguments from the startup shell script /usr/CM2/ESA/bin/esa specified in /etc/inittab.

  If the native agent process is not running, the SNMP Agent process and native agent process are started.

  If the native agent is running, the SNMP Agent process is started, and the native agent process is restarted.

• In Linux

  According to the run level of the system, the /opt/CM2/ESA/bin/snmpstart command (without any arguments) is executed from one of the following files:

  • /etc/rc.d/rc2.d/S55esa

  • /etc/rc.d/rc3.d/S55esa

  • /etc/rc.d/rc5.d/S55esa

  Only SNMP agent processes are started, regardless of whether the native agent is running. The starting of the native agent depends on controls on the OS side.
