Discontinue use of the Infoprint Server SNMP subagent

Description

In z/OS V2R2, the Simple Network Management Protocol (SNMP) subagent is no longer provided with Infoprint Server, so you must take steps to stop using it. The SNMP subagent lets network management systems (such as Ricoh Network Printer Manager for the web) communicate with PSF-controlled printers that do not have internal SNMP agents. However, because most newer printers contain internal SNMP agents, network management systems can communicate directly with these printers.

As an alternative to using a network management system to monitor PSF-controlled printers, you can use Infoprint Central, a web-based print management system. Infoprint Central can display the status of all your PSF-controlled printers. In addition, Infoprint Central lets you stop and start the printers, change printer work-selection criteria, and turn TCP/IP-connected printers online and offline.

Table 1 provides more details about this migration action. Use this information to plan your changes to the system.

Table 1. Information about this migration action
Element or feature: z/OS Infoprint Server.
When change was introduced: z/OS V2R2.
Applies to migration from: z/OS V2R1 and z/OS V1R13.
Timing: Before installing z/OS V2R2.
Is the migration action required? Yes, if you use the SNMP subagent. You are using the SNMP subagent if the start-daemons={snmpd} attribute is specified in the Infoprint Server configuration file. The configuration file's default location is /etc/Printsrv/aopd.conf. However, you might have specified a different location in environment variable AOPCONF in the aopstart EXEC.
Target system hardware requirements: None.
Target system software requirements: None.
Other system (coexistence or fallback) requirements: None.
Restrictions: None.
System impacts: None.
Related IBM® Health Checker for z/OS® check: None.

Steps to take

Follow these steps:
  1. If you use a network management system to monitor PSF-controlled printers, do one of these:
    • Configure the network management system to communicate with the printers directly.
    • Use Infoprint Central to manage the printers. To use Infoprint Central, you must customize PSF to use the Infoprint Server Printer Inventory.
  2. Stop the SNMP subagent daemon:
    1. (Optional) Edit the Infoprint Server configuration file (aopd.conf) to remove the snmp value from the start-daemons attribute. This step is optional because Infoprint Server will ignore the snmp value.
    2. If Infoprint Server is running, stop the SNMP subagent daemon (aopsnmpd). For example, enter this MVS START command to run the AOPSTOP procedure to stop daemon aopsnmpd: 
      START AOPSTOP,OPTIONS='-d snmpd'
