Monitoring policy settings

Use this page to view or change settings that control how the node agent monitors and restarts a process.

To view this administrative console page, click Servers > Application Servers > server_name. Then, under Server Infrastructure, click Java and Process Management > Monitoring Policy.

Configuration tab

Maximum Startup Attempts

Specifies the maximum number of times to attempt to start the application server before giving up.

Data type Integer
Ping Interval

Specifies the frequency of communication attempts between the parent process, and the process it has spawned. Adjust this value based on your requirements for restarting failed servers. Decreasing the value detects failures sooner; increasing the value reduces the frequency of pings, reducing system overhead.

For example, the parent process might be a node agent, and an application server might be the process it has spawned.

Data type Integer
Range Set the value greater than or equal to 0 (zero) and less than 2147483647. If you specify a value greater than 2147483647, the application server acts as though you set the value to 0.
Ping Timeout

When a parent process is spawning a child process, such as when a process manager spawns a server, the parent process pings the child process to see whether the child was spawned successfully. This value specifies the number of seconds that the parent process should wait (after pinging the child process) before assuming that the child process failed.

Data type Integer
Units Seconds
Range Set the value greater than or equal to 0 (zero) and less than 2147483647. If you specify a value greater than 2147483647, the application server acts as though you set the value to 0.
Automatic Restart

Specifies whether the process should restart automatically if it fails. On distributed systems, the default is to restart the process automatically. On a z/OS system, the default is to not start the process automatically.

If you change the value specified for this field, you must restart the application server and the node agent before the new setting takes effect.

If you change the value specified for this field, you must restart the application server before the new setting takes effect.

This setting does not affect what you specified for the Node Restart State setting. The two settings are mutually exclusive.

Data type Boolean
Default true (distributed) / false (z/OS)
Node Restart State

The setting only displays for the Network Deployment product. It specifies the desired behavior of the servers after the node completely shuts down and restarts.

If a server is already running when the node agent stops, that server is still running after the node agent restarts. If a server is stopped when the node agent restarts, whether the node agent starts the server depends on the setting for this property:
  • If this property is set to STOPPED, node agent does not start the server.
  • If this property is set to RUNNING, the node agent always starts the server.
  • If this property is set to PREVIOUS, the node agent starts the server only if the server was running when the node agent stopped.

This setting does not affect what you specified for the Automatic Restart setting. The two settings are mutually exclusive.

Data type String
Default STOPPED
Range Valid values are STOPPED, RUNNING, or PREVIOUS. If you want the process to return to its current state after the node restarts, use PREVIOUS.
