WAN example

A design center contains the following hosts configuration in a WAN:

LIM starts bld on the following hosts:

  • lsf.conf in Design Center A

    LSF_LIC_SCHED_HOSTS="hostA1.designcenter_a.com hostA2.designcenter_a.com hostA3.designcenter_a.com"

  • lsf.conf in Design Center B

    LSF_LIC_SCHED_HOSTS="hostB1.designcenter_b.com hostB2.designcenter_b.com hostB3.designcenter_b.com"

License Scheduler candidate hosts are listed in the following order of preference:

  • lsf.licensescheduler in Design Center A

    HOSTS=hostB1.designcenter_b.com hostB2.designcenter_b.com hostA1.designcenter_a.com hostA2.designcenter_a.com hostA3.designcenter_a.com

  • lsf.licensescheduler in Design Center B

    HOSTS=hostB1.designcenter_b.com hostB2.designcenter_b.com hostB3.designcenter_b.com

The following diagram shows hostB1.designcenter_b.com, the License Scheduler host for the WAN containing Design Center A and Design Center B.

How it works

The LSF LIM daemon starts the License Scheduler daemon (bld) on each host that is listed in LSF_LIC_SCHED_HOSTS in Design Center A and Design Center B.

Each host in the HOSTS list in Design Center A is a potential License Scheduler candidate in Design Center A and is running the bld daemon, but only one host becomes the License Scheduler host: the first host in the HOSTS list that is up and that is running the bld daemon. Similarly, the License Scheduler host in Design Center B is the first host in the HOSTS list that is up and that is running the bld daemon.

License Scheduler manages the licenses in Design Center A and Design Center B as follows:

  • Both design centers list hostB1.designcenter_b.com at the top of their HOSTS lists.

  • hostB1.designcenter_b.com is the License Scheduler host for Design Center A and for Design Center B.

  • The rest of the hosts in both design centers remain on standby as candidate License Scheduler hosts.

  • License Scheduler manages the license scheduling across the WAN connection.
