Preamble
Oracle PLSQL GLOBAL TEMPORARY TABLES are tables that are created for individual Oracle sessions.
Oracle CREATE GLOBAL TEMPORARY TABLE syntax:
CREATE GLOBAL TEMPORARY TABLE table_name
( column1 datatype [ NULL | NOT NULL ],
column2 datatype [ NULL | NOT NULL ],
…
column_n datatype [ NULL | NOT NULL ]
);
Parameters or arguments
- table_name – The name of the table you want to create.
- column1, column2, … column_n – The columns that you want to create in the global time table. Each column must have a data type. The column must be defined as NULL or NOT NULL, and if this value remains empty, the database takes on the default value of NULL.
Let’s consider the example of Oracle CREATE GLOBAL TEMPORARY TABLE:
CREATE GLOBAL TEMPORARY TABLE suppliers
( supplier_id numeric(10) NOT NULL,
supplier_name varchar2(50) NOT NULL,
contact_name varchar2(50)
);
This example will allow Oracle to create a global temporary table with a name.

- Database Performance Management
Financial institutions can improve hybrid-cloud database reliability by combining continuous observability, workload-aware monitoring, resilient architecture, capacity planning, and faster root-cause analysis across on-premises and cloud systems. Strong hybrid cloud database reliability depends on seeing performance, availability, replication, SQL, and resource risks in one place. Enteros supports this with deeper visibility that strengthens BFSI cloud database … Continue reading “How Can Financial Institutions Improve Database Reliability Across Hybrid Cloud Environments?”
What Database Metrics Should Banks Monitor for Real-Time Transaction Processing?
Banks should continuously track database metrics for banking, including transaction latency, throughput, CPU utilisation, memory pressure, disk I/O, query performance, locks, waits, connection usage, replication lag, and error rates. Effective database monitoring for banks helps teams detect performance degradation early, protect real-time transaction processing, maintain application reliability, optimise infrastructure resources, and respond faster to emerging … Continue reading “What Database Metrics Should Banks Monitor for Real-Time Transaction Processing?”
