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 reads in the following environment variables. These are read by user and child command
|----------|----------|------------|-------------------------------------------------------------------|
| Name | Type | Required | Description |
|----------|----------|------------|-------------------------------------------------------------------|
| ECF_HOST | <string> | Mandatory* | The host name of the main server. defaults to 'localhost' |
| ECF_PORT | <int> | Mandatory* | The TCP/IP port to call on the server. Must be unique to a server |
| ECF_SSL | <any> | Optional* | Enable encrypted comms with SSL enabled server. |
|----------|----------|------------|-------------------------------------------------------------------|
* The host and port must be specified in order for the client to communicate with the server, this can
be done by setting ECF_HOST, ECF_PORT or by specifying --host=<host> --port=<int> on the command line
