I have installed an Oracle 12c database on my development environment, which I start only once a while for integration testing. But today, it does not seem to start, or did it start but does not allow connections? Here are some clues:
- OS is Debian 8
- I use a shell script to start and stop the database
- $ORACLE_SID contains
- The hosts file contains
127.0.0.1 localhost and 127.0.1.1 Strada.nohoo.biz Strada
- The /u01/app/oracle/diag/rdbms/info/INFO/alert_INFO.log file ends with
Completed: ALTER DATABASE OPEN Sun Mar 11 20:27:57 2018 Shared IO Pool defaulting to 112MB. Trying to get it from Buffer Cache for process 4294. =========================================================== Dumping current patch information =========================================================== No patches have been applied =========================================================== Sun Mar 11 20:27:57 2018 db_recovery_file_dest_size of 4560 MB is 0.00% used. This is a user-specified limit on the amount of space that will be used by this database for recovery-related files, and does not reflect the amount of space available in the underlying filesystem or ASM diskgroup.

But all this does not look like a successful situation!
And finally, trying to connect with SQLplus ends up with
ORA-12547: TNS:lost contact
Thanks for you help!
