Quartz, Log4J and Data Queue

["Sameer Jaffer" <sijaffer@xxxxxxxxxxx>]

I am writing a servlet that is scheduled from quartz, uses logging with
log4j and gets/sends data to AS400 Data queue. Now my question is Does
the jt400 api for sending and receiving data from the data queue utilize
multiple threading and/or queue locking mechanism. What I mean by this
is if I schedule a process for a get and send for every second, and if
that first job is not complete, when the next process starts after the
first or second second, will I have locking issues, or missed/dropped
message issues? I understand that this is a little convoluted scenario,
but if this were the case, what would be the proper way to handle the
scheduling, logging, locking and performance?

 

Remember that quartz, spawns another thread when it starts a new job
while the previous job is still processing. Please help, your expertise
in this matter is greatly appreciated. 

 

 

Thank you,
