    Basic script for creating snapshot logs on masterrep site and
    snapshots on snapshot site - This is assuming that you have the
    site work done (setup master and snapshot sites)


    ----------------------- MASTER SITE ----------------------------
    CONNECT REPADMIN/xxxx@MASTERREPSITE

    -- SAI_PARAMETERS ---
    execute DBMS_REPCAT.CREATE_MASTER_REPOBJECT(-
    gname => '"WORKORDER_DETAIL"',-
    type => 'TABLE',-
    oname => '"SAI_PARAMETERS"',-
    sname => '"OWNER"',-
    copy_rows => TRUE,-
    comment => 'SAI_PARAMETERS table in WORKORDER DETAIL',-
    use_existing_object => TRUE);

    -- SAI_PARAMETERS ---
    execute dbms_repcat.generate_replication_support (-
    sname => 'OWNER',-
    oname => 'SAI_PARAMETERS',-
    type => 'table',-
    distributed => true,-
    min_communication => true);

    -- SAI_PARAMETERS ---
    CREATE SNAPSHOT LOG ON "OWNER"."SAI_PARAMETERS"
    TABLESPACE "WORK_ORDER"
    PARALLEL ( DEGREE 2)
    WITH PRIMARY KEY
    INCLUDING NEW VALUES;

    COMMIT;
    --------- SAI_PARAMETERS (CONFLICT RESOLUTION) ------------
    --
    BEGIN
    DBMS_REPCAT.DEFINE_COLUMN_GROUP(
    'SYSADM',
    'SAI_PARAMETERS',
    'SAI_PARAMETERS_GRP',
    'Column Group for update resolution - Snapshot wins');
    END;
    /
    BEGIN
    DBMS_REPCAT.ADD_GROUPED_COLUMN(
    'SYSADM',
    'SAI_PARAMETERS',
    'SAI_PARAMETERS_GRP',
    '*');
    END;
    /
    BEGIN
    DBMS_REPCAT.ADD_UPDATE_RESOLUTION(
    'SYSADM',
    'SAI_PARAMETERS',
    'SAI_PARAMETERS_GRP',
    5,
    'OVERWRITE',
    '*',
    NULL,
    NULL,
    'Update Conflict resolution - Snapshot wins');
    END;
    /
    BEGIN
    DBMS_REPCAT.ADD_UNIQUE_RESOLUTION(
    'SYSADM',
    'SAI_PARAMETERS',
    'PK_SAI_PARAMETERS',
    10,
    'DISCARD',
    '*',
    NULL,
    'Insert Conflict resolution - Master wins');
    END;
    /
    COMMIT;
    EXECUTE DBMS_REPCAT.GENERATE_REPLICATION_SUPPORT(-
    sname => 'OWNER',-
    oname => 'SAI_PARAMETERS',-
    type => 'table',-
    distributed => true,-
    min_communication => true)
    COMMIT;


    ----------------------- SNAPSHOT SITE ----------------------------

    CONNECT SNAPADMIN/XXX@SNAPSHOTSITE

    -- SAI_PARAMETERS ---
    CREATE SNAPSHOT "OWNER"."SAI_PARAMETERS"
    STORAGE ( INITIAL 1M NEXT 16384 MAXEXTENTS 249)
    PARALLEL ( DEGREE 2)
    LOGGING
    TABLESPACE "WORK_ORDER"
    BUILD IMMEDIATE
    USING INDEX TABLESPACE "USER_INDEX"
    STORAGE( INITIAL 16384 nEXT 16384 MAXEXTENTS 249 )
    REFRESH FAST
    ON DEMAND
    FOR UPDATE

    BEGIN

    END;
    /

    CONNECT OWNER/XXXX@SNAPSHOTSITE

    GRANT SELECT,INSERT,UPDATE,DELETE ON SAI_PARAMETERS TO PUBLIC
    ;
    drop public synonym SAI_parameters;

    CREATE PUBLIC SYNONYM SAI_PARAMETERS FOR OWNER.SAI_PARAMETERS
