I ran into a logical error “This connection has already been closed (NOSQL).” while running Grid DB Shell commands on Docker.
Following the documentation on the installation of Grid DB on Docker, I ran the command
docker exec -it griddb-server gs_sh
to start my Grid DB server on Docker and attempt to run some GridDB shell command
showcontainer
However, I didn’t get the list of container on the Grid DB database. I expect a response that show a table list of containers (available or not available) on the Grid DB database but got the response “This connection has already been closed (NOSQL).”
I tried other Grid Shell commands and some SQL commands but got the same response.
I realize that the error occurs due to starting the Grid Shell on root user instead of gsadm on your environment (most likely docker when running docker exec -it griddb-server gs_sh)
If you are using the docker environment, I will recommend you follow the steps below;
docker exec -it griddb-server gs_stat -u admin/admin To start the griddb-server
docker exec -it griddb-server /bin/bash To enter the griddb server environment
su gsadm To change to the user gsadm where we can access the griddb-server
gs_sh To enter the griddb shell and run successfully Grid DB command
While on other environment; You need to ensure you run the following commands before running SQL or TQL commands;
