When archive logs fail to transfer from the primary to the standby database, it creates gaps that prevent proper synchronization. Running this query on the standby database reveals which log sequences are present locally but missing at the destination, allowing administrators to take corrective action before the gap becomes too large. <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-1012089347386563" crossorigin="anonymous"></script> <ins class="adsbygoogle" style="display:block" data-ad-client="ca-pub-1012089347386563" data-ad-slot="5317081938" data-ad-format="auto" data-full-width-responsive="true"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> </p>
