In this appendix:. You may need to disable Oracle Database Vault to perform upgrade tasks or correct erroneous configurations. You can reenable Oracle Database Vault after you complete the corrective tasks.
You must perform maintenance tasks on Oracle Database Vault. You are about to install a third-party product, install an Oracle product, or perform an Oracle patch update whose installation may be prevented if Oracle Database Vault is running.
Any user can query this table. Turn off the software processes. Stop the dbconsole process in case it is running. For both single-instance and Oracle Real Application Clusters installations, use the following command:. If you use a cleartext password on the command line, you must include the nodecrypt option.
If you omit the password, DVCA prompts you for it. Preferably, omit the password and then enter it interactively when prompted. This option is required if you are not running DVCA in an xterm window. Select the Standard tab, right-click the following services, and from the menu, select Stop :.

I do not wish to wait for Oracle to provide a procedure to disable SSL version 3. This process may work on older versions. You take all responsibility for any issues you encounter by following these instructions. Of course, you also take the responsibility for operating your EM12c system in a way by which your encrypted connections can be trivially hacked, so make a decision appropriate to your environment.
I recommend you do NOT follow these steps and instead raise a priority Sev-1 service request with Oracle demanding an immediate, supported fix, but for those in a situation requiring an immediate response, I offer this post.
If you have not made a specific effort to disable it or applied a future patchset in which Oracle disables the functionality, you have SSL v3 enabled. How can you test and how can you validate that you have disabled it once complete?
I advise that you open up a copy of the Firefox browser, and go to the about:config page. The image below shows a secure setting of 1, and 3 for TLS 1. Double-click on each of the top two lines and change the setting to 0. The screen should now look like the image below.
Make sure you change this setting back once you have finished testing or you have created a huge security risk for this browser. See my previous post on Firefox security for more information. If the page loads and you see a login prompt like below, your EM12c installation allows insecure SSLv3 connections. After disabling SSLv3 you should return to this section, repeat these steps, and make sure that you get an error page instead of the login screen.
As an aside, MOS note Specifically, you need to modify the SSLProtocol declaration in four different configuration files:. You should now see an error like the following:. Now revert those Firefox security.This appendix contains:. You may need to disable Oracle Database Vault to perform upgrade tasks or correct erroneous configurations. You can reenable Oracle Database Vault after you complete the corrective tasks. The Oracle Database Vault user accounts have been inadvertently locked or their passwords forgotten.
See the tip under "Oracle Database Vault Accounts" for a guideline for avoiding this problem in the future. Any user can query this view. For Oracle RAC installations, repeat these steps for each node on which the database is installed. At this stage, Oracle Database Vault is disabled. You can perform the following types of activities:. This enables a Database Vault administrator to correct a misconfigured protection without having to disable Database Vault.
Perform the installation or other tasks that require security protections to be disabled. Oracle Label security must be enabled before you can use Database Vault. Skip Headers.

Network encryption is of prime importance to you if you are considering moving your databases to the cloud. Check the contents of the wallet. Notice the self-signed certificate is both a user and trusted certificate. Each side of the connection needs to trust the other, so we must load the certificate from the server as a trusted certificate into the client wallet and vice versa.
Check the contents of the client wallet. Notice the server certificate is now included in the list of trusted certificates. Check the contents of the server wallet.
Notice the client certificate is now included in the list of trusted certificates. You probably need to think about what cipher suites you want to support. Your decision my vary depending on the Oracle database and client versions. Make sure the client cipher suites match the server configuration.
Needless to say that your personal optimal settings may vary - either in size range or DOP - and highly depend on your target workload and business requirements only. You can enable parallel execution and determine the DOP in the following priority order:. This method is mainly useful for testing purposes, or if you have a particular statement or few statements that you want to execute in parallel, but most statements run in serial. This force method is useful if your application always runs in serial except for this particular session that you want to execute in parallel.
A batch operation in an OLTP application may fall into this category. For a query that processes objects with different DOP settings, the object with the highest parallel degree setting accessed in the query determines the requested DOP. Marketing Advertising Analytics Email. Oracle Database pages. Table of Contents 1 - About. How to enable a parallel execution: for a query. You can enable parallel execution and determine the DOP in the following priority order: hint.
I then ran IISCrypto and disabled the two protocols. Passed the security scan and proceeded, I thought everything was good to go. Now having a lot of issues getting the app server to connect to SQL. I do not want to load any certificates or use SQL encrypted. How do I get the flag to go away that is reporting that it's turned on. Check with them first, but I cannot believe they would want you forcing plain-text database connections.

OLE DB? SQL Native Client? Anytime I disable TLS v1. I've reached out to the vendor asking what protocol they are using. Feb 23 '18 at Active Oldest Votes. Yea, I've done that.

Featured on Meta. Responding to the Lavender Letter and commitments moving forward.Starting with this release, you can configure signature-based security for large object LOB locators. Parent topic: Changes in Oracle Database Security 19c.
Using the schema only account feature from Oracle Database release 18c, most of the Oracle Database supplied schemas users now have their passwords removed to prevent users from authenticating to these accounts. This enhancement does not affect the sample schemas. Sample schemas are still installed with their default passwords. For the default schemas that are schema only, administrators can still alter these accounts with passwords if they need to authenticate to the schema, but Oracle recommends changing the schemas back to a schema-only account afterward.
The benefit of this feature is that administrators no longer have to periodically rotate the passwords for these Oracle Database-provided schemas. This feature also reduces the security risk of attackers using default passwords to hack into these accounts. Existing user accounts active, rarely accessed, and unused users that are currently granted administrative privileges can be altered to be schema-only accounts.
This enhancement prevents administrators from having to manage the passwords of these accounts. The Active Directory administrator is responsible for configuring the connection parameters for Active Directory server, but does not need to configure the database to match this new Active Directory connection enhancement. This new support for partial DN matching adds the ability for the client to further verify the server certificate.
How to unofficially disable SSL v3 in Oracle Enterprise Manager 12c to mitigate POODLE attack
The client supports both full and partial DN matching. If the server DN matching is enabled, then partial DN matching is the default. Allowing partial and full DN matching for certificate verification enables more flexibility based on how the certificates were created. The unified auditing top-level statements feature enables you to audit top level user or, direct user activities in the database but without collecting indirect user activity audit data.
You can use this feature to audit only the top-level user directly issued events, without the overhead of indirect SQL statements. Top-level statements are SQL statements that users directly issue. These statements can be important for both security and compliance. In a multitenant database deployment, the pluggable database that generated a unified audit trail record must be identified in the audit trail.
