6、If all above are OK, The following statement to create the mview.

.(Red font need be replaced to step 2 db_link name)

   
   
   
   
    
    
    
    
    
  1. CREATE MATERIALIZED VIEW PRDADMC.PARAM_FLUX_SENDER TABLESPACE PRDADMC_SNAP_DATA 
    2. 
    
    
    
    
  2.  
    3. 
    
    
    
    
  3. BUILD IMMEDIATE USING INDEX TABLESPACE PRDADMC_SNAP_INDEX  REFRESH FORCE ON DEMAND AS 
    4. 
    
    
    
    
  4.  
    5. 
    
    
    
    
  5. SELECT * FROM "PRDADMC"."PARAM_FLUX_SENDER"@TETRIX21_TKUDBX31.DKTETRIX.NET; 
    6.

 7、Executing ‘select * from user_refresh;

Create Mview step by step_第6张图片

8、We need replace the RNAME value of script (statement in red),using step 7 select result.

   
   
   
   
    
    
    
    
    
  1. begin 
    2. 
    
    
    
    
  2.  
    3. 
    
    
    
    
  3.   DBMS_REFRESH.ADD(name => 'PRDADMC. R_PRDADMC_TKUDBX31_1',list => 'PRDADMC.PARAM_FLUX_SENDER',lax => TRUE); 
    4. 
    
    
    
    
  4.  
    5.

  6.  
    7. 
    
    
    
    
  7. /

9、Creating the materialized view log. Attention, all the red font, you need to change.

   
   
   
   
    
    
    
    
    
  1. CREATE MATERIALIZED VIEW LOG ON PRDADMC.PARAM_FLUX_SENDER TABLESPACE PRDADMC_SNAP_DATA; 
    2.


10、Please use this SQL to know how many slaves in this instance.

   
   
   
   
    
    
    
    
    
  1. select mowner, r.snapsite, count(*) 
    2. 
    
    
    
    
  2.  
    3. 
    
    
    
    
  3. from   sys.slog$ s, sys.reg_snap$ r 
    4. 
    
    
    
    
  4.  
    5. 
    
    
    
    
  5. where  s.snapid=r.snapshot_id(+) 
    6. 
    
    
    
    
  6.  
    7. 
    
    
    
    
  7. group by mowner, r.snapsite 
    8. 
    
    
    
    
  8.  
    9. 
    
    
    
    
  9. order by 1 
    10.

11、When we know the slaves, we need to operate all the step at every instance.

 

12、We need grant right to VISU_xxxx account, and create synonym.

 

   
   
   
   
    
    
    
    
    
  1. grant select on PRDADMC.REF_SPECIFIC_CUSTOMER  to visu_prdadmc;  
    2. 
    
    
    
    
  2.  
    3. 
    
    
    
    
  3. create synonym visu_prdadmc.REF_SPECIFIC_CUSTOMER  for PRDADMC.REF_SPECIFIC_CUSTOMER; 
    4. 
    
    
    
    
  4.  
    5. 
    
    
    
    
  5. alter session set current_schema= visu_prdadmc; 
    6. 
    
    
    
    
  6.  
    7. 
    
    
    
    
  7. select * from dba_synonyms where table_name='REF_SPECIFIC_CUSTOMER' 
    8.
