- NOTE: Starting in R2019a the following name changes occurred:
- MATLAB Distributed Computing Server was renamed to MATLAB Parallel Server
- mdce_def was renamed to mjs_def
- mdce binary was renamed to mjs
Why do I receive errors when starting a job manager or worker in MATLAB Parallel Server 1.0 (R14SP1+)?

When I start a job manager or worker on my host host_name, where host_name is the name of my host, as follows:
./startjobmanager.sh -name MyJobManager (on UNIX)
startjobmanager -name MyJobManager (on Windows)
I receive errors such as ERROR: Could not find activation system. The cause of this problem is: ====================================================== Could not locate mdce service daemon at host: host_name.domain.com and port: 1098. ====================================================

This enhancement has been incorporated in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:
According to RFC 2396, RFC 952, and RFC 1123, the underscore (_) is not a valid character in a hostname . You need to change your hostname so that it does not contain an underscore (_). You can use a dash (-) instead of an underscore.
