When a support call comes in — &quot;the database was slow last night, can you check the logs?&quot; — the fastest first pass is a single grep across every log file in the diagnostic directory. This one-liner, drawn from the shutdownabort.com DBA Quick Guides (Andrew Barry, 2007–2013, preserved via the Wayback Machine), scans all alert logs under the Oracle diagnostic root and prints every line containing an ORA- error code.</p>
