[sqlalchemy] oracle database error.
I am using Sqlalchemy with Oracle backend in my project. I am running into listener issues with the Oracle database. Here are the steps that I am following: 1. My connection string. sqlalchemy.url=oracle://root::password@localhost:1521/orcdb 2. Environment variables . export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/ server export PATH=$PATH:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib export ORACLE_SID=orc10g The following is the error that I get when my project tries to connect to the Oracle db.
