login.sql

If you use a login.sql script to set the SQL*Plus environment from your current working directory, you will see that it will not run anymore in 12.2. This is a security feature, and a good occasion to explain how sqlplus finds the scritps to run, on Linux.

For my test I have login.sql, LOGIN.SQL and script.sql in the following directories

$ tree /tmp/mytest/
/tmp/mytest/
├── a
│   ├── login.sql
│   ├── LOGIN.SQL
│   └── script.sqlL
├── b
│   ├── login.sql
│   ├── LOGIN.SQL
│   └── script.sql
├── login.sql
├── LOGIN.SQL
└── script.sql

I’m going to the parent directory
cd /tmp/mytest

The scripts display their name:

+ head login.sql LOGIN.SQL script.sql
==> login.sql LOGIN.SQL script.sql <==
prompt Hello from /tmp/mytest/script.sql
