Hi,
I am planning copy my source database to target database. Here my challenge is the source is a non-compression database and target is a compression database. How can i reach the optimize downtime. My sandbox database is 4TB. It is an system copy-> oracle->source system export-> based on as-abap-> table splitting
I did a system export it took me the system down time of 8 hours with 44 parallel jobs. I took 2 jobs for r3load process for one cpu ( 22 cpus).
Now for optimizing I am going for table split preparation and I am very new to it. If you have any documents can you please share it to my email.
now I am planning to do table splitting preparation. For this table splitting preparation.
I downloaded the MIGCHECK_2, MIGMON, MIGTIME, ORABRCOPY and SPLIT as it suggested in note: 784118 - System Copy Tools for ABAP Systems
I also found the couple of notes 1875778 - Performance Optimization for System Copy Procedures and 936441 - Oracle settings for R3load based system copy.
I need some more stuff from the experts so i can go ahead and kick off the table splitting preparation.
Note: here my operating system and database are same for source and target.
O.S: Unix and database : oracle.
Thanks in advance.
