Scenario 2

The cluster alias PLANET is changed to SPHERE. The old cluster alias PLANET is not accessible over the network.

Implications:

The following jobs might get stuck in DepWait state:

ALPHAS::ALP1
PRD1/PRD2::PROD4
PLANET::PL1
PLANET::PL2

Solution:

Define the logical name NSCHED$ALIAS_GROUPS as follows on the ALPHAS and PRD1/PRD2 clusters:

$ DEFINE/TABLE=LNM$SYSCLUSTER_TABLE NSCHED$ALIAS_GROUPS "PLANET, SPHERE"

Results after defining the logical name:

All jobs run as expected. Dependency records are updated as follows:

Job ALPHAS::ALP1 is dependent on job SPHERE::E1

Job SPHERE::PL1 is dependent on job ALPHAS::ALP3

Job SPHERE::PL2 is dependent on job PRD2::PROD2

Job PRD1/PRD2::PROD4 is dependent on job SPHERE::M1
