Nodes Configration strange warning
Posted: Tue Oct 27, 2009 2:10 am
Hi all,
I faced a strang behavior in the configration file , which i need to understand
we are using datastage 7.5.2 on IBM AIX Server with 4 processors and 24 GB ram
i've made 8 nodes pointing to the same file system , i.e. the same node and copied it 8 times with diffrent name and i have some questions now :
1- There are warrning while checking configration file appears only on node1 the warning is
Warning: Config file checker on node node1 can only create 413 processes. Ascential Software recommends that ORCHESTRATE users be able to create at least 64 processes per logical node. This node is one of 8 on the physical node csdsp1. Therefore, ORCHESTRATE users should be able to create 512 processes on this node
although the 8 nodes refer to the same file system i.e. the datasets & scratch folders are the same for the 8 nodes , so i think that it is strang behavior to warn in one node only
2- does making 8 file systems , i.e. mount points and making each node point to different file system will improve the performance of parallel jobs ?
3- what is the difference between physical nodes and logical nodes , i really need to understand that
i tried to search dsxchange for these questions , i found really some usefull information but i need more illustrated answers for my questuions
i really appreciate your effort and support
