# title: Error "connection lost to database" could happen when application creates few local attachments (using XNET) simultaneously
|
|
# decription:
|
|
# Test uses 15 threads and each of them launches loop for 10 iterations with making attach/detach from DB.
|
|
# We use Python package with name "threading" here, but it should be declared as global inside class because of fbtest specific
|
|
# (otherwise test will failed with message "global name 'threading' is not defined").
|
|
# No such declaration is needed in normal way (i.e. when running code directly from Python, w/o using fbtest).
|
|
# Each instance of worker thread has dict() for storing its ID (as a key) and pair of values (success and fail count) as value.
|
|
#
|
|
# We have to ensure at the final point that for every of <THREADS_CNT> threads:
|
|
# * 1) number of SUCCESSFUL attempts is equal to limit that is declared here as LOOP_CNT.
|
|
# * 2) number of FAILED attempts is ZERO.
|
|
#
|
|
# Confirmed bug on 4.0.0.1598, 3.0.5.33166 (checked both SS and CS).
|
|
# It was enough 3 threads (which tried to establish attachments at the same time) to get runtime error:
|
|
# "- SQLCODE: -901 / - connection lost to database".
|
|
#
|
|
# Checked on 4.0.0.1607, 3.0.5.33171.
|
|
# :: NB ::
|
|
# Execution time for this test strongly depends on major version and server mode:
|
|
# 4.0 Classic: ~9"; 3.0.5 Classic: ~5";
|
|
# 4.0 Super: ~5"; 3.0.5 Super: ~1".
