The best scheduler avaiable is autosys it is a 3rd party tool. By this we can do all the scheduling and have attributes to incorporate dependency between various abinitio graphs. Through autosys command jobs we run the script file corresponding to any abinitio graph.

In ab initio there are no specific scheduling options as in informatica. What we can do is use cronjob options as in unix

You can do anything in Ab Initio, depends on the logic you use


Say there are 10 jobs 1,2,3,4,5 .. 10 and all the graphs are deployed as script.
Suppose 1-4 graps should run at the same time and sequential pattern after that.

These are steps you may get into --

1. Create a script in Unix that is required for sequential run,viz.

seq_2_run.sh would call the scripts generated by deployment of the graphs in the following manner -

vi seq_2_run.sh

nohup 5.ksh &
nohup 6.ksh &
nohup 7.ksh &
nohup 8.ksh &
nohup 9.ksh &
nohup 10.ksh &

2.Create a scheduler graph in abinitio.

a. Take five script execute components,
b. Call the 1.ksh 2.ksh 3.ksh and 4.ksh in four script execute components and keep them all in the same phase, say phase 0.
c. Call the seq_2_run.sh in four script execute components and assign it as phase 2.

3. Run the graph.

Output :

1-4 would run at the same time and seqential pattern after the completion of the prior.
