Problem:
...
When
...
I
...
run
...
a
...
gene
...
expression
...
query,
...
I
...
get
...
a
...
Java
...
stack
...
trace
...
error
...
regardless
...
of
...
whether
...
the
...
query
...
or
...
study
...
is
...
new
...
or
...
previously
...
saved
...
or
...
deployed.

Solution
This error occurs in Linux when caIntegrator can not access study data, which by default is stored in the system temporary directory (/tmp).
...
Every
...
time
...
the
...
application
...
is
...
restarted,
...
the
...
contents
...
of
...
this
...
/tmp
...
directory
...
are
...
flushed,
...
so
...
when
...
the
...
user
...
attempts
...
to
...
run
...
a
...
query
...
after
...
the
...
restart,
...
the
...
query
...
will
...
not
...
be
...
able
...
to
...
access
...
the
...
study
...
data
...
it
...
needs,
...
regardless
...
of
...
whether
...
the
...
query
...
is
...
new
...
or
...
if
...
it
...
was
...
saved
...
before
...
the
...
restart.
...
An
...
example
...
of
...
the
...
Java
...
stack
...
trace
...
error
...
is
...
attached
...
below
...
as
...
a
...
plain

The exact error message you get may vary slightly from the contents of the attached text file. Note that this error is not recorded in the server log; it is only displayed in the caIntegrator browser window after the query attempt fails.
The best solution to this problem is to change the study data storage location from the default /tmp directory to a permanent location. For instructions on how to change the study storage location, please refer to the KB article at https://wiki.nci.nih.gov/x/oZKNAg.
