TEMP Tablespace in Oracle: Monitoring, Errors & Best Practices (Day 10)

Welcome to Day 10 of the 100-Day Oracle DBA Challenge. In today’s lesson, we break down Temporary Tablespaces and Tempfiles in Oracle Database — a critical topic that directly impacts query performance, sorting operations, and overall database stability. Temporary tablespaces act as Oracle’s workspace for large operations that cannot fit into memory, including sorts, hash joins, index creation, and complex SQL execution. Poor TEMP sizing or monitoring can lead to slow queries, ORA-1652 errors, and failed reports. In this video, you’ll learn: • What a Temporary Tablespace is in Oracle • The difference between TEMPFILE vs DATAFILE • Why tempfiles do not generate redo • How to create and manage TEMP tablespaces • How to monitor TEMP usage using Oracle views • Common TEMP-related errors and how to fix them • Best practices every Oracle DBA must follow This lesson is essential for junior DBAs, Oracle learners, SQL developers, and anyone preparing for Oracle DBA certifications or real-world production environments. 📌 Key takeaway: A poorly sized TEMP tablespace can crash queries and bring workloads to a halt — proper monitoring and tuning are mandatory. 👍 Like this video if it helped 💬 Comment which TEMP issue you’ve encountered most 🔔 Subscribe to follow the full 100-Day Oracle DBA Challenge
