Introduction:

Pdm_vdbinfo is one of the best tools for determining when to increase the number of database agents. The pdm_vdbinfo command produces a report that shows you what each database agent is currently doing in your CA Service Management environment.

 

There are two variable shown in the output which could provoke confusion: "Num Agents running" vs "Max Config Agents"

Answer:

Open NX.env file and look for MAX_DBAGENT and  NX_VIRTDB_AGENTn variables:

@NX_MAX_DBAGENT=6                      <=Define SELECT Agents

@NX_VIRTDB_AGENT1=                      <=Define UPDATE Agents, AGENT#0 is not shown in NX.env.

...

@NX_VIRTDB_AGENTN=

 

Max Config Agents : Specifies the maximum number of Select agents to start. The NX_MAX_DBAGENT variable sets this value. In this example, the bpvirtdb_srvr is configured to start up a maximum of 6 SELECT database agents. 

 

Num Agents running :Identifies the total number of UPDATE agents currently connected to the bpvirtdb_srvr process.  It is the sum of SELECT and UPDATE agents: MAX_DBAGENT +  NX_VIRTDB_AGENTn values.
