例如以下图

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQveGlhb2ZhbjIzeg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="">

CAUSE

There's a script in ORACLE_HOME/sqlplus/admin which is called glogin.sql.  This script is automatically run when the user starts SQL*PLUS or uses the Connect command, hence any command
added to it will be executed. 



Checking the script, it had a "select * from v$instance;" statement added. It was always executing this statement when SQL*PLUS was started or when Connect was issued, and this statement is returning the ORA-01034 when invoking DBCA.

SOLUTION

1. Check the glogin.sql script in ORACLE_HOME/sqlplus/admin and make sure it has no statements that could cause the ORA-01034.

    disable glogin.sql (mv glogin.sql glogin.sql.bak)  

2. If the issue is still not resolved, then please log an SR with Oracle Support.
