Problem:

What does the following error message mean?

ASLM: Errno -301002 when running COBOL application

Resolution:

The message means that Application Server licensing is unable to open a licensing file (/var/mfaslmf/aslmodf), which is shipped with the product (Server Express 4.0).

The reason given in the error code is that the file does not exist. The aslmodf file has to be present in the /var/mfaslmf directory every time that a COBOL application runs.

A re-installation of the Application Server Licensing system should solve the problem.
