RE: 1.What is the use of parameters in datastage job?

there are two types of parameters we can create

1.Job level parameters. - Those parameters only use in that particular job.U can create in Desinger.

2.Project Level parameters. - Those parameters can use into multi jobs under that particular project.Using Admin we have to create the project level parameters.

Use - Dynamic value passing at runtime(while running of job) like file_name , path etc.so, runtime u can pass the file name or path or whatever u want.so ur job wil be dynamic take that parameters and do perform the work.

i hope u understand the parameters usage.

Regards,

Anwar

Parameters are helps to enter values at run time. and also makes secure by not to forcing a hard coding.

Unit testing is the one mainly deals with a single job.

system testing is the one deals with system compatabilty.

integration testing deals with entire set of jobs that meets business requirements.

Schudeling jobs helps to set a timer to run a job at a perticuler event of time

error hanling is done through a stage in job sequences.

We can remove duplicates using remove duplicate stage
