customer has 3 environments: 2 single (dev and pre) and 1 RAC-ASM (prod). We are doing the first complete refresh from PROD to PRE, then from RAC to Single, following Note Cloning Oracle Applications Release 12 with Rapid Clone [Article ID 406982.1] , which has a reference to Cloning an Oracle RAC System, which refers to follow Note Cloning Oracle E-Business Suite Release 12 RAC-Enabled Systems with Rapid Clone [ID 559518.1].
Following this Note, you have to create a Database Image in an stage directory, then you need unless the same database size as free space for this db image. This is not an option for very big application databases, then our idea is not to create the db image, but cloning database separatelly, following steps in Option6 in cloning Note 406982.1.
The question is, we have to refresh DB and app tier from PROD (RAC ASM) to PRE (single), colud we ignore Note " Cloning Oracle E-Business Suite Release 12 RAC-Enabled Systems with Rapid Clone [ID 559518.1]" and follow Clone Article ID 406982.1 specially Option 6, recovering PROD database separatelly with rman duplicate or we have to follow Note 559518.1 and create a db image? Any experience cloning R12 from RAC to single?
If this task will be done often to keep the environment updated. You may want to create an stand by database, single. This will allow you to clone easily, without touching much prod.
In you lines, are fine, just ensure the oracle_home from the single environment, have all the patches as the interpretability note state.
Can any one provide step to step configuration for RAC to RAC cloning in EBS R12
How to clone multi tier (2 node application Tier) using adcfgclone ... Thanks in Advance.
