Usage: pico -list <ip/host> ... | -view <pico name> | -add <ec name> <EC> <ip/host>group name> | -delete <ec name> <EC> <ip/host> | -mark_for_shutdown <ec name> <EC> <ip/host> <true | false>group name>

This command is used to:

  • Listlist, view add, add, or delete pico instancesSignal to the Platform that an EC is scheduled to be shut down
Note
titleNote!

With the introduction of STR, it is typically no longer required to add pico instances. Provided that the value of the property pico.rcp.server.host is set to its default value or that the value can be found in the address attribute of the container, EC, and SCs are implicitly added via the STR.

If pico.rcp.server.host does not match with any of the container addresses you can grant access to the system by:

  • Adding the missing address in the container attribute additional-addresses in the STR.
  • Setting the Platform property mz.pico.skip-registration-check to true. This will grant access for any pico host.
  • Adding a new pico host in the Pico Manager.

The Memory column is a comma-separated list of Used, Committed, and Maximum memory, and Response Time is measured in milliseconds.

If Error Status indicates "Error", an OutOfMemoryError has occurred and additional information will be included in the output. For example, in case of an OutOfMemoryError on the Platform, the following could be shown:

Code Block
languagetext
themeEclipse
Platform: Mon Jan 23 09:59:47 CET 2012 OutOfMemoryError on platform at platform-e6410. 
See log/platform.log for more information

OutOfMemoryError is further described in Out of Memory Info in System Log.

If Error Status indicates "Connection failure", an RCP error has occurred.

If Marked for Shutdown is set to true, the EC is scheduled to be shut down and will not be assigned workflows.

The following command displays the status of the pico instance named ec1.
