    Creating materialized view thru db link?

    Hi

    Anyone knows how to create a view/materialized view of table in remote server thru database link.

    I have created the following:

    1. database link orcltst
    SQL>create database link orcltst connect to tester identifed by tester using 'orcltst';

    2. Try to create a view remotely from another server:
    SQL>CREATE MATERIALIZED VIEW abcview
    AS SELECT * FROM abc@orcltst;


    But it failed to create the view.

    Can anybody share the expertise on this

    Thanks you so much for your help

    First as tester in orcltst run (change the names of the tablespaces):

    CREATE MATERIALIZED VIEW LOG ON abcview TABLESPACE MV_LOG_TS
    PCTFREE 60 PCTUSED 30 MAXTRANS 255
    STORAGE (INITIAL 1M NEXT 1M MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0)
    WITH PRIMARY KEY INCLUDING NEW VALUES;

    Then on the snapshot DB:

    CREATE MATERIALIZED VIEW abcview
    PCTFREE 10 PCTUSED 40 MAXTRANS 255
    STORAGE (INITIAL 1024K NEXT 1024K MINEXTENTS 1 MAXEXTENTS 2147483645
    PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1)
    TABLESPACE TS_DATA_NAME
    BUILD IMMEDIATE
    USING INDEX TABLESPACE TS_INDEX_NAME
    PCTFREE 10 INITRANS 2 MAXTRANS 255
    STORAGE(INITIAL 256K NEXT 256K PCTINCREASE 0 MINEXTENTS 1 MAXEXTENTS 2147483645
    FREELISTS 1 FREELIST GROUPS 1)
    REFRESH force WITH PRIMARY KEY
    START WITH trunc(sysdate) + 4/24
    NEXT trunc(sysdate+1) + 4/24
    AS
    SELECT * FROM abc@orcltst;

    This MV will be fast refreshesd every morning at 4AM.
