Bigfile Tablespace Shrinking in Oracle Database 23ai

Oracle Database 23ai November 10, 2024

The "Long-Term Support" edition of Oracle Database 23c brings important improvements to database management, performance, and storage effectiveness. The ability to reduce the size of Bigfile tablespaces is one of Oracle Database 23c's noteworthy features. This enables database managers to maximize storage, recover underutilized space, and enhance the general effectiveness of database operations. Here's a closer look at the new shrink feature, Bigfile tablespaces, and how to make the most of it.

What is a Bigfile Tablespace?

Using a single data file that can expand to a very high size—up to 128 TB or more, depending on the block size—a bigfile tablespace is a sort of Oracle tablespace made to manage massive volumes of data. By lowering the number of files in the database, bigfile tablespaces make management easier. This is particularly helpful for databases that include enormous datasets. These big files, however, might collect idle space as data usage changes and objects are added or removed, raising storage costs and affecting speed.

Why Shrink Bigfile Tablespaces?

Bigfile tablespace shrinkage solves several important issues:

Recovering Unused Space: A Bigfile tablespace may have a significant amount of unused space as data is transferred or erased. You can take back this space with the new shrink option, freeing up storage for other purposes.
Cutting Storage Expenses: Storage is still used for unused space in a Bigfile tablespace. You can optimize space consumption and reduce your overall storage costs by reducing the tablespace.
Enhancing the Performance of Databases: Performance may be enhanced by a slimmer tablespace since the database engine will have less superfluous data to handle, particularly during backup, recovery, and maintenance procedures.

Key Features of Bigfile Tablespace Shrinking in Oracle Database 23c

Oracle Database 23c has made it easier to handle huge databases by streamlining the process of decreasing Bigfile tablespaces. Here are a few noteworthy aspects:

Dynamic Shrinking: To minimize interference with users and applications, you can dynamically reduce the size of a Bigfile tablespace while the database is operational and online.
Automatic Space Reclamation: Oracle Database 23c eliminates the need for manual monitoring by automatically identifying and recovering unneeded space.
Flexible Shrinking Options: By letting you choose a target size, the shrink operation makes sure that the tablespace is downsized to suit your requirements.

How to Shrink a Bigfile Tablespace in Oracle Database 23c

In Oracle Database 23c, shrinking a Bigfile tablespace is simple. A detailed tutorial on how to carry out this operation can be found below:

Determine which Bigfile Tablespace needs to be shrunk.
To start, find out how much spare space is in your Bigfile tablespace by looking at its current usage. To verify space utilization, use the following query:

Shrink the Bigfile Tablespace

Use the new ALTER TABLESPACE SHRINK command to shrink the Bigfile tablespace. This command can be customized to shrink to a specific size or automatically reclaim as much space as possible.

To shrink to a specific target size:

To automatically reclaim maximum available space:

Verify the Shrink Operation

After the shrink operation completes, verify the results by checking the tablespace size again:

Considerations for Bigfile Tablespace Shrinking

Although reducing the size of a Bigfile tablespace has advantages, there are a few things to think about:

Data Fragmentation: The shrink operation might not be able to recover all of the space if the tablespace contains fragmented data. To improve space reclamation, a coalescence or rearrangement procedure might be conducted beforehand.
Storage Thresholds: If you are establishing a target size, be sure that it is sensible. If more data is added later, an excessive amount of shrinking may cause out-of-space issues.
Performance Impact: Large tablespaces may still see some slowdown during the shrink process, even if Oracle Database 23c reduces the performance impact of shrink operations. If at all possible, run this process at off-peak hours.

Benefits of Bigfile Tablespace Shrinking

Optimized Storage: By making better use of storage, shrinking Bigfile tablespaces can help cut expenses related to excessive data space usage.
Better Manageability: The database is easier to administer, backup, and recover by maintaining ideal tablespace sizes, which lowers administrative overhead.
Improved Performance: By simplifying data access and cutting down on pointless I/O operations, a well-maintained tablespace enhances database performance.

Conclusion

For DBAs seeking to maximize storage and boost database performance, Oracle Database 23c's new Bigfile tablespace shrinking capability is an effective tool. Bigfile tablespaces are kept affordable and manageable over time via Oracle Database 23c's dynamic shrinking features, customizable settings, and automated space reclamation. This function, which provides a practical means of recovering unneeded space and improving database performance, is particularly helpful in large-scale settings where storage efficiency is crucial.

Empowering Women in Tech: My Journey with the Girls Who Code Self Paced Program

AI August 12, 2024

The technology industry is fast evolving, and more women are entering the field, reshaping what it means to be a leader in technology. Taking part in the Girls Who Code Self-Paced program was a genuinely profound event. Along with helping me develop my technical abilities, the program stressed the value of expanding chances for women in technology and the power of education to effect change.

Dive Into Technology: Mastering AI, Cybersecurity, and Web Programming

Web programming, cybersecurity, data science, and artificial intelligence were all well-represented in the curriculum. Working on practical projects forced me to use coding languages like HTML, CSS, JavaScript, and Python in real-world situations. Every assignment forced me to use my innovative and effective problem-solving abilities, which are vital in everyday life as well as technology.

The format of the program was perfect for anyone wishing to learn more and explore various facets of technology at their own pace. In addition to strengthening my knowledge in front-end web development, it gave me the chance to investigate challenging subjects like data encryption and machine learning.

The Greater Picture: Advancing Women in Technology

While technical skills were an important aspect of the program, what really stuck out to me was the emphasis on encouraging women in tech. I heard about how programs like Girls Who Code are fostering an environment that inspires young women to pursue and excel in STEM fields. Seeing how initiatives like these are providing opportunities and a nurturing environment for ambitious female programmers is encouraging.

Considering My Future in Technology

The experience strengthened my love of technology and my resolve to promote diversity in the industry. I can't wait to put what I've learned into practice as I continue my tech career, whether it be through upcoming projects, teamwork, or even coaching others who are just starting out with coding.

I'm glad to be a part of the movement that is empowering women in technology. More than just a learning experience, the Girls Who Code program offered participants the chance to develop, meet like-minded individuals, and help ensure that everyone has a seat at the tech table in the future.

A Sweet Day at Watermark: Senior Connect’s Ice Cream Social and More!

Non-Profit August 11, 2024

At Senior Connect, our purpose is to deliver joy, connection, and assistance to the senior community. Our most recent visit to Watermark served as the ideal illustration of that goal. It was a day full of laughs, smiles, and meaningful encounters, from setting up a lovely ice cream bar to planning activities and providing assistance when required.

Nothing quite says summertime like ice cream, so we decided to provide the elders at Watermark with this delightful treat. Our group put up an ice cream bar that attracted a lot of interest right away. We took care to provide an assortment of toppings and flavors so that everyone could design their ideal dessert. Cups were stacked high with scoops of ice cream, sauces, sprinkles, and more in a matter of seconds. Everybody was enjoying their customized sweets, and the excitement in the room was great. The lovely grins and conversation over sweet sweets exemplified the happiness that arises from simple pleasures.

While the ice cream was a tremendous hit, we did not stop there. We also arranged a card game that made everyone laugh a lot and brought out the competitive side in some of them. The residents' interactions, jokes, and enjoyment of one another's company served as a potent reminder of how crucial it is to promote social connections.

During our visit, we saw that Watermark's storage area could need some organization, so we pulled up our sleeves and went to work. We made sure everything was tidy and in order, went over the supplies, and arranged things so they were easier to get. Small actions like these can have a major impact on how well centers operate and how well staff and residents are taken care of.

We appreciate the Watermark staff's hospitality. We are even more determined to positively influence our community as a result of this experience, and we hope to have many more days just like this one in the future. We are grateful to the elders at Watermark for letting us be a part of their lives.
