Windows subagent

On Windows™, OnSNMP comprises the following files. The table also lists the directories in which the 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 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 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 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.
