Welcome to Database Patch News, Buda Consulting’s newsletter of current patch information for Oracle and Microsoft SQL Server. Here you’ll find information on available patches—including security patches—and desupported versions recently made available.
Why should you care about patching vulnerabilities and bugs? Two big reasons:
-
- Unpatched systems are a top cyber attack target. Patch releases literally advertise vulnerabilities to the hacker community. The longer you wait to patch, the greater your security risk.
- Along with running a supported database version, applying the latest patches ensures that you can get support from the vendor in case of an issue. Patching also helps eliminate downtime and lost productivity associated with bugs.
Here are the latest patch updates for Oracle and SQL Server:

Do I really need Oracle Enterprise Edition? Do I need Oracle Enterprise Edition in order to have a standby database? What version of Oracle do I need?
We get questions like these a lot. Oracle’s editions and features can be a bit overwhelming. This post shares some key information that I hope will make your choice easier.
To keep this post to a manageable length, this post deals only with Oracle Version 12c and Version 19c, and excludes Oracle cloud offerings. A future post will cover those feature sets.
Oracle Standard Vs. Enterprise
For each version covered below, I took the feature set from Oracle’s licensing documentation and listed those things that are available only in the Enterprise Edition of Oracle, and not in any of the Standard Editions.
But before we look at the specific features available in each version, let’s explore two important categories of features:
Data Guard
One of the more frequently used options in Enterprise Edition is Data Guard. A set of Data Guard features is listed in the first table for each edition below. These are used to implement high availability; that is, having a standby database available that is kept up to date with your primary production database in case your primary database goes down.
If Data Guard related features are the only set of “Enterprise-only” features that you need, then you may still be able to use Oracle’s Standard Edition. Here’s why:
DBvisit Standby, an alternative to Oracle’s Data Guard, provides an active standby database using any version of Oracle. You will still need to license the database software on both the primary and the standby server, but both can be much less expensive Standard Edition licenses.
Oracle Security
Oracle has a number of important security options.
The advanced security option is an extra cost option that is only available with Enterprise Edition. This includes transparent data encryption, data redaction, data masking and subsetting (very helpful for development environments), and other security options. To adequately secure sensitive data at the database level, we advise that you use advanced security, and thus Oracle Enterprise Edition.
With that said, if you are not using advanced security, and the only Enterprise-only option you need is Data Guard, then we recommend taking a good look at Dbvisit.
Oracle Version 12c Features
Below are the features that are only available in Enterprise Edition for Oracle 12c. If you need anything on this list, then you need Oracle Enterprise Edition. Period!

If you need any of the above features, then you may need Oracle Enterprise Edition, depending on the specifics as listed in the notes.
That’s it!
Your DBA team should be able to tell you if you need/use these Enterprise-only features.
If you don’t need any of these features, then potentially you can save many thousands of dollars by using the Standard Edition instead.
Oracle version 19c Features
OK, that’s it for 12c. Oracle 19c is essentially the same but with a somewhat different, more “evolved” set of options. The considerations mentioned above remain valid.
First, let’s look at the 19c features that definitely require Enterprise Edition:

If you need any of the above, the you must use Oracle Enterprise Edition
Now we look at the features that are included in the Oracle 19c Standard edition, but are limited.

Oracle Multitenant – # of PDBs |
The number value in each column indicates the maximum number of pluggable databases (PDBs) that can be created for each offering.
For all offerings, if you are not licensed for Oracle Multitenant, then you may have up to 3 user-created PDBs in a given container database at any time. |
| Manageability |
SQL Plan Management |
SE2: Only one SQL plan baseline per SQL statement is allowed and SQL plan evolution is disabled. Limits on baseline capture methods as well.
The following DBMS_SPM functions and procedures are not allowed: CONFIGURE, LOAD_PLANS_FROM_AWR, LOAD_PLANS_FROM_SQLSET, and all functions and procedures associated with SQL plan evolution. |
If you are not using pluggable databases, or if three databases are enough, and if you are not using sophisticated plan management, then you can likely use Standard Edition.
If you know of any other enterprise-only options that are not listed here, or if you think I misstated anything, please comment. I’d like to hear from you. Also, if you know of other good disaster recovery alternatives, let me know.
If you are not sure about any of this, or you just want to double-check your thought process, leave a comment or give me a call and I will be happy to have a conversation with you about it.
by Robert Buda | Mar 19, 2015 | Cloud, Database Architecture, Oracle
If you’re thinking of moving to Oracle Database 12c, “the first database designed for the cloud,” one of the most compelling reasons could be the Oracle Multitenant Architecture option. In this revolutionary new architecture, you can “plug” many Oracle databases into a single container database—no application changes required.
Let’s quickly head off any potential confusion around the term “multitenant.” That word has been used for awhile in relation to sharing data elements (records) across databases, especially in contexts like Software-as-a-Service (SaaS) delivery. This scenario is now best referred to as tenant striped database. With Oracle’s multitenancy, you can run many databases within one container, with several databases potentially sharing a common set of metadata.
The advantages of Oracle’s multitenant architecture are sweeping, driving economies of scale across both capital and operating expenses. First, plugging multiple databases into a single, multitenant container creates the highest density yet possible, with shared memory and background processes to further enhance hardware utilization. The advantages over the schema-based consolidation possible with Oracle 11 are 1) no application changes required; and 2) pluggable databases are isolated for improved reliability and security.
Next, multitenancy enables rapid provisioning and cloning. Creating, moving and cloning pluggable databases takes just seconds with new SQL commands. Patching and upgrades are also simplified and accelerated—just unplug/plug to an upgraded container! (What will you do with all the time that will save?) The overall theme is “manage many as one” across tasks like backup and recovery. You even get new capabilities in the Resource Manager to optimize allocation of resources among pluggable databases.
What are the best use cases for Oracle Multitenant? There are quite a few but these four stand out:
- Application development/testing
Multitenant makes it very quick, simple, safe and efficient for individual engineers to rapidly provision and recycle private copies of a few “master test databases.” Just the productivity benefits of this one use case might be sufficient to justify implementing multitenancy.
- Infrastructure consolidation
Multitenancy supports the use of fewer, more powerful physical servers.
- Delivering and supporting SaaS applications
Multitenancy is ideal for deploying separate instances of identical applications to individual “tenants.” This model is predicted to be popular among cloud vendors in particular.
- Enabling Database-as-a-Service (DBaaS) in a private or hybrid cloud.
Multitenancy has a built-in self-service provisioning mechanism that makes it straightforward to enable self-service provisioning of databases; e.g., in development test environments.
Can you upgrade to Oracle Database 12c and not deploy the multitenant option? Yes… but why would you want to? You can even dip a toe in the water by plugging just one database into a container, which requires no additional license.
If you’re considering upgrading to Oracle Database 12c and want to talk over the architecture and design considerations, I invite you to contact Buda Consulting for guidance on analyzing your requirements and architecting an optimal solution.
