# title: Online validation during DML activity in other connection leads to message "Error while trying to read from file" and "page in use during flush (210), file: cch.cpp line: 2672"
# decription:
# In order to check ticket issues this test does following:
# 1. Change on test database FW to OFF - this will increase DML performance.
# 2. Create two tables: one for inserting rows ('test') and second to serve as 'signal' to stop DML:
# inserts will be done until 2nd table (with name = 'stop') is empty.
# 3. Adds to SQL script DML (execute block) that will be used in ISQL session #1: it inserts rows
# into 'test' and checks after each inserting table 'stop' on presence there at least one row.
# This 'stop-row' will be inserted into 'stop' table in another ISQL session.
# 4. Launches ISQL connection #1 in separate (child) process. This ISQL will start 'heavy DML'.
# 5. Proceeds several online-validation actions by using synchronous call of 'FBSVCMGR action_validate'.
# Adds result of each validation to log.
# 6. Launches ISQL connection #2 in separate (child) process and give to this session trivial job:
# 'insert into stop(id) values(1); commit;'. This will cause ISQL session #1 to stop its activity
# because it runs in transaction with TIL = RC.
# 7. Outputs log of ISQL-1 and online validation results.
#
# Tested on WI-V3.0.0.32008, SS, SC and CS. Result: OK.
# Updated since WI-V3.0.0.32064: reduced key-length from extremely huge (1000) to "normal" value 36,
# otherwise get 'Statement failed, SQLSTATE = 54000 / Implementation limit exceeded / -Maximum index level reached'.
