I get this error message each time I try to connect to my Oracle XE local database under Ubuntu 15.10 :
user@user-X220:/u01/app/oracle/product/11.2.0/xe/network/admin$ sqlplus SQL*Plus: Release 126.96.36.199.0 Production on Thu May 5 20:58:13 2016 Copyright (c) 1982, 2011, Oracle. All rights reserved. Enter user-name: SYS Enter password: ERROR: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist Linux-x86_64 Error: 2: No such file or directory Process ID: 0 Session ID: 0 Serial number: 0
I have read on some forums that i have to delete my /dev/shm repository :
sudo rm -rf /dev/shm sudo mkdir /dev/shm sudo mount -t tmpfs shmfs -o size=2048m /dev/shm
I tried actually to do that but it seems that
/dev/shm is used by several processors including my firefox navigator.
Any help will more than welcome.
