*******
.. rubric:: Output of :code:`--help=replace`
The following help text is generated by :code:`ecflow_client --help=replace`
::
replace
-------
Replaces a node in the server, with the given path
Can also be used to add nodes in the server
arg1 = path to node
must exist in the client defs(arg2). This is also the node we want to
replace in the server
arg2 = path to client definition file
provides the definition of the new node
arg3 = (optional) [ parent | false ] (default = parent)
create parent families or suite as needed, when arg1 does not
exist in the server
arg4 = (optional) force (default = false)
Force the replacement even if it causes zombies to be created
Replace can fail if:
- The node path(arg1) does not exist in the provided client definition(arg2)
- The client definition(arg2) must be free of errors
- If the third argument is not provided, then node path(arg1) must exist in the server
- Nodes to be replaced are in active/submitted state, in which case arg4(force) can be used
Replace will preserve the suspended status, if this is not required please re-queue first
After replace is done, we check trigger expressions. These are reported to standard output.
It is up to the user to correct invalid trigger expressions, otherwise the tasks will *not* run.
Please note, you can use --check to check trigger expression and limits in the server.
For more information use --help check.
Usage:
--replace=/suite/f1/t1 /tmp/client.def parent # Add/replace node tree /suite/f1/t1
--replace=/suite/f1/t1 /tmp/client.def false force # replace t1 even if its active or submitted
The client considers, for both user and child commands, the following environment variables:
ECF_HOST <string> [mandatory*]
The main server hostname; default value is 'localhost'
ECF_PORT <int> [mandatory*]
The main server port; default value is '3141'
ECF_SSL <any> [optional*]
Enable secure communication between client and server.
ECF_HOSTFILE <string> [optional]
File that lists alternate hosts to try, if connection to main host fails
ECF_HOSTFILE_POLICY <string> [optional]
The policy ('task' or 'all') to define which commands consider using alternate hosts.
The options marked with (*) must be specified in order for the client to communicate
with the server, either by setting the environment variables or by specifying the
command line options.
