Test your Archive logs by importing them into a standby database that already exists, or which you create for just this purpose.
A standby database with the purpose of testing the archive log needs the same disk space but needs hardly any CPU and memory resources.
An associated SAP System is not required. This method is the most secure, since a recovery is actually executed.
By using the brarchive options '-w use_rmv' or '-w first_rmv' These options implicitly call RMAN functions to check the archive logs, even if you do not use RMAN to save the database.
This method is particularly reliable when you have set db_block_checksum to true (in accordance with the parameter recommendations ), and you use '-w use_rmv'.
By dumping an archive log. If a dump shows an error, it can be assumed that corruption has occurred. Even if no error is displayed the archive may STILL be corrupted.
