I've an installer that uses sqlplus at the moment but I would like to use SQLcl instead. When I replace sqlplus with sqlcl I find that my installer runs a lot longer. After some debugging I found that starting and then executing the first sql statement can take up to 12 seconds. When I do the same thing in SQLPlus it goes a lot faster within 2-3 seconds. What can I do to make the startup time a bit faster? Are there some Java switches that might help?
