Though Shareplex can be run in archivelog or noarchivelog on both source and target, on source it is highly desirable to run it in archivelog mode whereas on target it can be run in either mode, though running it in archivelog mode has many advantages. The question arises as to whether a target database can be resync'd and recovered using hotbackup reconcile if it is running in noarchivelog mode.
It is only possible to take a hotbackup of a database if it is running in archivelog mode. But a database running in noarchivelog can be recovered using archive logs from another database. For this reason, it is possible to use the hotbackup with reconcile procedure for resync of a target database that is running in noarchivelog mode.
If there are any issues during the process, it is always possible to change the mode of the target database to archivelog and then do the recovery, or create a new target database with archivelog mode and then do the recovery.
Oracle backup and recovery are within the DBA domain, Shareplex support does not provide or troubleshoot procedures on how to perform Oracle backup and recovery.
