Have any of you had much experience using Java in a batch environment
on the System i?
Much of the customer's workload is batch - currently written in
COBOL. They are experiencing problems in getting experienced COBOL
programmers and this situation is likely to be exacerbated as their
in-house pool shrinks when their mainframe applications are replaced
during the 2008 - 2009 timeframe.
Everything else in the shop is Java WebSphere (but not on i). They
want to keep the data on the i but need to address the programmer
problem.
My gut tells me that the Java performance will be an issue - but I
have no experience to back that up one way or the other. COBOL
already outperforms RPG in batch and I've never seen a Java program
beat out RPG performance wise so ... but if somebody has some
experience that suggests that Java is viable as an option in this
arena I'm more that happy to be wrong.
No religious wars please.
