We have had problems where the WRITE to an SFS file does not close
quickly enough for a subsequent READ. IBM may have addressed all those
problems.
I believe someone suggested doing a LOCK on the file. We do just that
with a LOG file that we have for an application that has data put into
it by several SVMs somewhat concurrently.
We use a LOCK when the SVM want do do a write and test for it before
attemting to do a WRITE. You could put the LOCK on the WRITE and test
before the READ if the LOCK exists.
Our code looks somewhat like:
b2bfile = "B2BLOG" date("S") "L"
"PIPE CMS CREATE LOCK" b2bfile "UPDATE SESSION",
"| VAR MESSAGE"
"PIPE CMS QUERY LOCK" b2bfile ,
"| STEM LOCK_MSG."
"PIPE CMS DELETE LOCK" b2bfile "| HOLE"
