A new cluster alias PRODS is introduced on PRD1/PRD2 cluster. The jobs PROD1 and PROD2 are modified to run on any cluster node.
Implications:
When the job PROD1 completes on node PRD2, its dependent job ALPHAS::ALP2 won't start. When the job PROD2 completes on node PRD1 , its dependent job PLANET::PL2 won't start. If either of the PRD1/PRD2 nodes is down, jobs PROD3 and PROD4 might get stuck in DepWait state.
Solution:
Define the logical name NSCHED$ALIAS_GROUPS as follows on the ALPHAS and PLANET clusters:
$ DEFINE/TABLE=LNM$SYSCLUSTER_TABLE NSCHED$ALIAS_GROUPS "PRODS, PRD1, PRD2"
Results of the above logical name definition:
All jobs run as expected. The dependency records are updated as follows:
Job ALPHAS::ALP2 is dependent on job PRODS::PROD1
Job PLANET::PL2 is dependent on job PRODS::PROD2
Job PRODS::PROD3 is dependent on job ALPHAS::ALP4
Job PRODS::PROD4 is dependent on job PLANET::M1
