Oracle 10g Real Time Backup

Question

Hi
My company need to set database real time backup for Oracle 10g release 2 (Standard Edition).
I see in Oracle Database 10g Product Family [Oracle Database 10g Product Family|http://www.oracle.com/technology/products/database/oracle10g/pdf/twp_general_10gdb_product_family.pdf] not support the Data Guard.
Can I do it in Oracle 10g SE ?
Thanks in advance

Answer 1

hi,
trouble is the cost of EE can be quite expensive
another way of creating a psuedo (hope I spelt that correctly) dataguard would be to script a method of shipping archive files to a DR server.
Live System
=========
             BEGIN
          IF ORACLE ONLINE THEN
                        SWITCH LOG;
                   END IF;
                   IF ANOTHER INSTANCE OF SCRIPT RUNNING (LOCAL OR REMOTE) THEN
                             ERROR;
                             EXIT;
                   END IF;
          IF (STANDBY NOT ONLINE) THEN
                          ERROR;
                          SEND EMAIL;
                          EXIT;
                   END IF;
                   GET LAST SHIPPED LOG FILE TIMESTAMP FROM THE REMOTE SITE OR FROM LOCAL SERVER;
                    WHILE LOG > SHIPPED LOG FILE TIMESTAMP DO
                              TRANSFER LOG FILE TO REMOTE SITE;
                              DO CHECKSUM ON LOG FILES;
                              IF NOT MATCH THEN
                                     RETRY TRANSFER;
                                     IF FAILURE 3 TIME THEN
                                           ERROR;
                                           SEND EMAIL;
                                     END IF;
                      END IF;
                              ' GOT THIS FAR SO ALL IS OK
                              MARK THE LOG FILE AS TRANSFERRED;
                    WEND;        
DR System
========
          BEGIN
               CREATE A LOCK SEMAPHORE;        - Only one instance allowed
                             CHECK LAST APPLIED LOG FILE;
               IF CONNECTION TO LIVE SERVER OK THEN
                                     CHECKSUM  NEXT LOG FILE WITH LIVE SYSTEM;
                                     IF CHECKSUM NOT SAME THEN
                                              IF LOG FILE ON ITS WAY FROM LIVE THEN
                                                       EXIT;
                                              END IF;
                                              WHILE  LOGFILE EXISTS DO
                                                        GET NEXT LOG FILE FROM LIVE;
                                              WEND;
                                     END IF;
                             ELSE
                                     ' Extra work
                                     APPLY NEXT LOG FILE
                             END IF;
               APPLY LOG FILES;
                             WORKOUT NO OF LOG FILE APPLIED;
                             KEEP SPECIFIED PERCENTAGE LOG FILES;
                             DELETE EXTRA LOG FILES;
                             TRANSFER LAST APPLIED LOG FILE ATTRIBUTES TO LIVE SERVER;
                             EXIT;
                     END;       I cannot give you the actual code that I have as there are some more bits that I have added for our client but what it does is give you an over view of the process involved for creating a pseudo DG environment.
