OCT 24 / 9AM ET Register nowRun DQC Process
Runs a ONE plan or component in a new Java process: the task waits until the process finishes. This allows you to run the ONE plan within the new JVM while using a specific Java version and runtime parameters (such as memory settings).
The plan is validated before the run: if the plan is invalid, the task fails with FINISHED_FAILURE state and log details into a log. Logs of the process are stored in the task resources folder. The STDOUT log also contains a copy of the process command.
This task requires the Ataccama Home system or user environment variable to be correctly set, otherwise the task might fail.
Make sure that ATACCAMA_HOME is set for the user running the online server (especially when the server is started as a Windows service; see Set ATACCAMA_HOME on Linux for Linux instructions).

Set ATACCAMA_HOME on Linux
The Run DQC Process task is a separate Java task, so it does not inherit the ATACCAMA_HOME
variable.
To set ATACCAMA_HOME
for Run DQC Process on Linux, you have to set it as a global variable.
Make sure the variable is set by the user running the online server.
To set the global variable:
-
Navigate to the root/home, for example,
/home/<user_name>
. -
Open the hidden file
.bash_profile
and add the following parameter:export ATACCAMA_HOME=/one20/app/server/runtime
Make sure the parameter points to the correct distribution.
-
Stop the server.
-
Log out from your Linux account and log back in.
-
Start the server.
