    How to check the Oracle version from the installed Oracle database RDBMS?

    Using the following queries, we can check the version of Oracle has been installed.

    SQL>select * from v$version;
    Oracle Database 10g Express Edition Release – Product
    PL/SQL Release – Production
    CORE Production
    TNS for 32-bit Windows: Version – Production
    NLSRTL Version – Production

    SQL>select * from product_component_version;
    —————————————- ———— ———-
    NLSRTL Production
    Oracle Database 10g Enterprise Edition Prod
    PL/SQL Production
    TNS for 32-bit Windows: Production

    Interpretation and understanding of Oracle version numbering:

    First digit is Major database release number
    Second digit is Database maintenance release number
    Third digit is Application server release number
    Fourth digit is Component specific release number
    Fifth digit is Platform specific release number

    For Example take output of above sample:


    Oracle 10 <=Major database release number
    .2 <=Database maintenance release number
    .0 <=Application server release number
    .1 <=Component specific release number
    .0 <=Platform specific release number

    Thanks and regards,
