Problem Note 18396: Queries or WHERE clauses run against large data sets can cause
SAS/SHARE® server to hang
With some queries or WHERE clauses that run against large data sets
through a SAS/SHARE server, the server might become unresponsive. For
example, a query such as the query shown below, when run against a table
that has 20 million observations, might not yield to other users or
requests.
select idvar from libref.table where lowcase(textvar) ? "some text"
The problem is that the underlying BASE engine yields only after a given
number of selected observations are read, rather than after raw
observations are read. In this situation, setting LRPYIELD= to a higher
value in PROC SERVER will not help.
