On Windows, OnSNMP comprises the following files. The table also lists the directories in which the HCL Informix® installation procedure installs each file.

Table 1. OnSNMP files and associated directories
File	Description	Directory
infxsnmp.dll	Library that provides the interface between onsnmp.exe and the master agent. The HCL Informix installation procedure installs one infxsnmp.dll on each workstation. The initialization process for the master agent loads infxsnmp.dll.	%Windows%\system32
onsnmp.exe	Subagent program. The HCL Informix installation procedure installs an onsnmp.exe file for each database server.	%INFORMIXDIR%\bin
onsrvapd.exe	Server discovery process, which starts onsnmp.exe for each database server that starts. The HCL Informix installation procedure performs the following tasks for onsrvapd.exe: Installs one onsrvapd.exe on each workstation Creates the Informix Server Discovery Process for SNMP in the control panel and configures it to start automatically when the system reboots	32-bit platforms: %Windows%\system32 64-bit platforms: Windows\SysWOW64

When you install the Informix database server, the installation procedure automatically installs OnSNMP. When you start the Informix database server that is on a network that uses SNMP, onsrvapd.exe detects this event and starts OnSNMP for the database server. When the database server halts, onsrvapd.exe stops OnSNMP for that database server.
