License Management with FLEXlm and COBOL

• The license client (HP Micro Focus Object COBOL/UX)

The license client, HP Micro Focus Object COBOL/UX, is linked with

the FLEXlm Client Library that provides the communication with

the license server. During execution, the license client communicates

with the vendor daemon to request a license.

The License Request Process

When you run a FLEXlm-licensed application, a license is automatically

requested and the following process occurs:

1. The license client, HP Micro Focus Object COBOL/UX, ﬁnds and

reads the license ﬁle to determine the license server node and port

number of the license manager daemon, lmgrd.

2. The license client establishes a connection with lmgrd and requests

connection to the vendor daemon speciﬁed for this license.

3. lmgrd responds to the license client with the hostname and assigned

port number for the requested vendor daemon speciﬁed for this

license.

4. The license client then disconnects from lmgrd and connects to the

correct vendor daemon.

5. The license client requests the check out of its license from the vendor

daemon and the request is either granted unconditionally (execution

will continue), granted with overdraft warning (execution will

continue after a delay), or denied (the license client will terminate

with a licensing error).
