    sqlplus: half a dozen failed to initialize SQL*Plus SP2-0067: sp1 message document. msb not found SP2-0750: You may need to set ORACLE_HOME to your own Oracle software directory. If the voice message file exists. Then the root cause of this problem is usually PATH.

    I recently completely uninstalled the 11g client (using the universal installer) while installing the latest 10g full client on a Windows XP workstation. When I try to run SQLPLUS I get:

    SP2-0750: You may need to set ORACLE_HOME to Oracle Software Directory

    I’m sure sp1us.msb is in C:oracleproduct10.2.0client_1slqplusmesg (12Kb size)

    and I tried removing the ORACLE_HOME environment variable completely. Fortunately, in both cases I get the same error

    I tried to set ORACLE_HOME=C:oracleproduct10.2.0client_1 (note the backslash) and got another error saying Oracle is not working properly (sorry I didn’t write that) . errors).

    I uninstalled and reinstalled the 10g client at least 3 years ago.

    Home» SQL & PL/SQL» Client Tools» 6 SQL*Plus Initialization Errors (Oracle Instant Client 12102 win10)



    My sysadmin, on behalf of 12c, walked me through the installation process of Oracle Instant Client meticulously. Basically copying the best folder to C:Program Filesoraclnt12102 and setting environment variables at the top:
    and update PATH.

    When I run the ORACLE_HOME folder in sqlplus everything works fine.

    But when I call it from another file (C:>sqlplus) I get the message:
    Error 10 when initializing SQL*Plus
    SP2-0667: Sp1 message file not found.msb
    SP2-0750: You may need to set ORACLE_HOME in the program directory of your Oracle software

    What am I doing wrong (other than I have Win10 ^^)
