How to Check and Analyze Oracle Table Data Size? – Tips

November 18, 2024May 25, 2024 by admin

In Oracle, the size of a table can be checked using the `SELECT` statement along with the `SUM` and `LENGTH` functions. The `SUM` function calculates the total number of rows in the table, while the `LENGTH` function determines the average length of each row. By multiplying these two values, we can estimate the total size of the table in bytes.

Knowing the size of a table is important for several reasons. It helps in capacity planning, performance tuning, and cost optimization. By understanding the size of a table, database administrators can allocate appropriate resources to ensure optimal performance and avoid potential bottlenecks. Additionally, it aids in estimating the storage requirements for backups and data archiving purposes.

Check Oracle Wait Events – Simple and Practical Guide

November 13, 2024April 27, 2024 by admin

Wait events provide insight into why a session is waiting and the resources it is waiting for. Some common wait events include:

db file sequential read
db file scattered read
latch: cache buffers chains
log file sync
library cache: load into buffer

The impact of wait events can vary depending on the type of wait event and the duration of the wait. Some wait events, such as db file sequential read, can be caused by normal database operations. Other wait events, such as latch: cache buffers chains, can indicate a problem with the database configuration or hardware.
