How To Create A Secure Network In Just 14 Days!

Today, more than ever, people are realizing the need for more privacy and security in their lives. With advances in technology, it is easier than ever for someone who wants to do you harm to get your information. This is why I feel it is more important than ever for each one of us to be aware of the basics of creating a secure private network. Let's face it... no matter how careful you are, at some point, you are going to click on a link or open an attachment from someone you don't know well. Or perhaps you will visit a website you didn't intend to visit. No matter what, if you are not 100% careful, your personal info can and WILL end up in the wrong hands. But don't worry. That isn't the only way your info can (and probably WILL) get into trouble. There are many other ways as well. And there are scammers and spammers and hackers of every nationality who are always on the lookout for new ways to get your info.

But don't despair. Creating a secure private network does NOT have to be difficult. In this month's newsletter, I'm going to reveal to you exactly how to go about doing just that...

STEP 1 - Determine What You Will Be Using Your Private Network For!

Do you need to send out announcements to everyone on your email list? Are you going to use your private network to receive emails from people you don't know? If so, you need to make sure your email program is set up to filter out unwanted emails so they don't clutter up your mailbox. Another thing you should think about is...

Does Anyone You Give Access To Your Network Have A Criminal Mind Or Perhaps An Intelligence Agency Mind?

If someone you give access to your network has even a shred of evil in them, it could ruin your life. There are many people (with more power than me) who would like to see you suffer a painful and slow death. These are the same people who would love to get their hands on the info you put on websites like this one. If you do not take steps to secure your private network, these people will get exactly what they want... which is...

All Of Your Info!

STEP 2 - Determine What Information You Will Give Out To Your Private Network!

Think about what you are going to put on your website and any other place you are going to make your network available to the world. It is a good idea to think about putting a little "secret" code in all your important info. This way, even if someone does get access to your info, it won't mean much to them. Unless they happen to have access to someone with the proper "keys". By the way, this is also a good idea for all your credit card numbers, bank account numbers, social security numbers, and all those other things which if abused can ruin your life... or at least make your life very uncomfortable.

STEP 3 - Give Your Network A "Fingerprint" Or "Mark" Of Some Kind!

Put a little "tag" on your website or any other info you give out to your private network so you will know if someone else has had access to it. The fingerprint or mark should be easy to detect. For example, if you are giving someone your email address, you could use a special character like this: email@email.com

And every time someone else tries to use that email address, a little alarm will go off in your mind and you will know right away if someone else has been using it. If your network is going to have a physical location, you could use a special color like red to represent an unauthorized person... and... use another color like green for you. Or perhaps a different kind of "mark" could be used.

By the way, there is no need for you to be paranoid about all this. Even if all these measures are not taken, your info will still be safe... because...

All Of This Is Just A Little Extra Protection You Are Giving Yourself!

Bottom-line:

 If you don't take some basic precautions, your personal info will end up in the wrong hands... and... it could ruin your life. So please... do yourself a favor and take a few minutes out of your life to learn how

How To Delete Huge Rows In Oracle Table Using Parallel Sessions Query Quickly

 

Traditional file-based systems are slow and tedious to access. In addition to that, they suffer from redundancy and inconsistency. Having said that, these issues can be easily resolved if you use an indexed database. Indexed databases are much faster than traditional file-based systems because they use an automated process to search for specific information. Also, since every piece of data has an index, it is redundant and consistent.

How to delete a huge table with more than 100 million rows in Oracle 19c. There are 2 ways to perform a conditional rollback in Oracle. If you have an AUTONOMOUS transaction running then you should use the built-in mechanism to perform a ROLLBACK. Otherwise, if you have a TRANSACTIONAL block of code (BEGIN...END) then you should use the ABORT command to halt the execution of your current block of code and return control to the calling program.

The best way to learn something is to teach it to someone else. So, I am going to teach you another very important SQL statement called the MERGE statement. The MERGE statement is a very powerful statement and is used to combine data from multiple tables or views into a single result set for easier processing. You can use the MERGE statement when you need to combine rows from different tables based on the values in one or more columns. Consider the following example: Let's say you have three tables: Customers, Orders, and Order_Items. Here is how the three tables might look like:

DELETE sets the index to be checked for each row to be deleted. In this case, it's the unique constraint on the column named "job_id".

I am not concerned about recovery though and some may hence want the checkpoint.

In this article, you will learn how to use the Oracle DELETE statement to remove rows from a table. All the rows whose column is 1 in such a table are also deleted automatically by the database system. Note that the COMMIT WORK statement ensures both DELETE statements execute in all or nothing manner, which prevents the orphaned rows in a such table in case the second DELETE statement fails.

A: Learn how to use SQL to clean up your data and protect yourself against malicious or accidental changes to your tables. This will prevent corrupting data, unnecessarily slowing down your application, and causing serious problems for you and your customers.

B: Learn how to use SQL to clean up your data and protect yourself against malicious or accidental changes to your tables. This will prevent corrupting data, unnecessarily slowing down your application, and causing serious problems for you and your customers.

A: Use the REPLACE command to replace each instance of a specified string in all matching rows. Use the WITH REPLACE option to specify a backup filename and a backup type. If you don't specify the WITH REPLACE option, the database system will create a new file with the same name as the original file and the extension changed from.dbf to.

I am not concerned about recovery though and some may hence want the checkpoint. Checkpointing is very handy and it is especially helpful when you are testing at high load levels or testing on large datasets. However, be careful not to use it as a crutch to avoid having to make difficult decisions. Instead, use it to give yourself a little "breathing room" to make an intelligent decision.

Archiving Tables Each of these tables must be empty for the Archive-Preview or Archive and Purge programs to run. If your data set gets too big, the system will create a new table automatically and copy the data from the old table into the new one. While this is happening, it will also archive the old table and keep it available for you to restore if needed. This process continues until all the data is archived. Then the system deletes the old table and makes the new one the current table. You can get more reading on our Oracle DBA Tips blog.

Just disable all indexes temporarily and put commit in the end of the loop of PL/SQL block. Execute your PL/SQL block or delete the statement. It will delete millions of records within seconds and execute commit. After execution of this task, Just rebuild all indexes for taking deletation effect.
