Services

Agent Technology for z/OS is comprised of the following services, which are a subset of the CA services on the distributed platforms:

awservices

Service controller.

aws_orb

Object request broker (that is, the communications handler).

aws_sadmin

SNMP handler. This service is also responsible for maintaining the MIBs within the Object Store in the UNIX System Services (USS) zSeries File System (zFS).

All of the z/OS-based agents communicate with the Agent Technology for z/OS services, which in turn communicate with the various NSM machines. This communication occurs using the TCP/IP protocol. By default, the following ports are used by these services:

• 6665-UDP-type port used by sadmin for SNMP requests.
• 7770-TCP-type port used for ORB->ORB communications (Release 2.0-2.1).
• 7774-TCP-type port used for ORB->ORB communications (Release 2.2-3.0 and 11.0).
• 9990-TCP-type port used by awservices (request port).
• 9991-TCP-type port used by awservices (control port).

Review the TCPIP.ETC.SERVICES file to determine if any other service has been registered to use any of these ports.

You can also issue the netstat command (at the ready prompt in TSO) to determine if any of the default ports are already in use prior to starting the Agent Technology services.
