I have a problem with my Oracle XE 188.8.131.52.
Today I have tried to change account, under which are services running (OracleXE and OracleXEListener).
My new functional account has is in group administartors on the PC, where Oracle is running.
I have restarted PC after change and after restart I could see that services were started.
When I tried to connect, I got an error "tns listener does not currently know of sid given in connect descriptor".
I have checked listener with LSNRCTL STATUS and I could see, that there are missing services XE and XEXDB.
So my personal feeling is, that service OracleXE is not started correctly...
If I return the service account back - to Local system, it is working correctly.
Please, could you advice me, what I should check?
You may need to put your users into appropriate groups. See the membership of the critical group with:
net localgroup ora_dba
It probably includes your local system user, and no-one else.
