I felt myself stupid when I lost a few minutes to undestand this error:
SQL> startup pfile=init_corpdb.ora ORA-29760: instance_number parameter not specified
Do you belive the solution was simply to set a number in ORACLE_SID?
Take a look:
dbsrvr>echo $ORACLE_SID corpdb dbsrvr>export ORACLE_SID=corpdb_1 dbsrvr>sqlplus / as sysdba SQL*Plus: Release 184.108.40.206.0 Production on Sun Jun 28 00:18:05 2015 Copyright (c) 1982, 2009, Oracle.
