How to Add New Disk To Virtual Machine using Oracle

Virtual disks are stored as files on the host computer or on a network file server. It does not matter whether the physical disk that holds the files is IDE or SCSI. A virtual IDE drive can be stored on an IDE drive or on a SCSI drive. So can a virtual SCSI drive.

On Learning To Use A Virtual Machine

Never used one before the course required me to use one.

You might have heard JVM (Java Virtual Machine) coming with the JDK (Java Development Kit) and JRE (Java Runtime Environment). And we have Oracle’s Virtual Box that is equipped with having multiple virtual machines being stored and used if necessary. Now, let’s go into details about how you can use various virtual machines.

Oracle Kills 402 Bugs in Massive October Patch Update

Business software giant Oracle is urging customers to update their systems in the October release of its quarterly Critical Patch Update (CPU), which fixes 402 vulnerabilities across various product families.

Well over half (272) of these vulnerabilities open products up to remote exploitation without authentication. That means that the flaw may be exploited over a network without requiring user credentials.

The majority of the flaws are in Oracle Financial Services Applications (53), Oracle MySQL (53), Oracle Communications (52), Oracle Fusion Middleware (46), Oracle Retail Applications (28) and Oracle E-Business Suite (27). But overall, 27 Oracle product families are affected by the flaws. Users can find a patch availability document for each product, available here.

“Oracle continues to periodically receive reports of attempts to maliciously exploit vulnerabilities for which Oracle has already released security patches,” according to the company’s release on Tuesday. “In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches. Oracle therefore strongly recommends that customers remain on actively-supported versions and apply Critical Patch Update security patches without delay.”

While details of the flaws themselves are scant, two of the critical vulnerabilities disclosed by Oracle rank the highest severity score – 10 out of 10 – on the CVSS scale.

These include a flaw in the self-service analytics component of Oracle Healthcare Foundation, which is a unified healthcare-analytics platform that is part of the Oracle Health Science Applications suite. The flaw (CVE-2020-1953), which can be remotely exploited without requiring any user credentials, requires no user interaction and is easy to exploit, according to Oracle. Affected supported versions include 7.1.1, 7.2.0, 7.2.1 and 7.3.0.

The second severe flaw (CVE-2020-14871) exists in the pluggable authentication module of Oracle Solaris, its enterprise operating system for Oracle Database and Java applications (part of the Oracle Systems risk matrix). The flaw is also remotely exploitable without user credentials, requires no user interaction and is a “low-complexity” attack. Versions 10 and 11 are affected.

Sixty-five of the vulnerabilities also had a CVSS base score of 9.8 (and six had a score of 9.4) out of 10, making them critical in severity.

Oracle did offer some workarounds, advising that for attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Users can also reduce the risk of successful attack by blocking network protocols required by an attack.

However, both these approaches may break application functionality, and Oracle does not recommend that either approach be considered a long-term solution as neither corrects the underlying problem.

“Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply Critical Patch Update security patches as soon as possible,” according to the company.

Oracle releases its CPUs on the Tuesday closest to the 17th day of January, April, July and October.

Previous quarterly updates have stomped out hundreds of bugs across the company’s product lines, including one in April that patched 405. There are also out-of-band updates; in June for instance, Oracle warned of a critical remote code-execution flaw in its WebLogic Server being actively exploited in the wild.

Python Packages in SQL Server – Get Started with SQL Server Machine Learning Services

Introduction

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.

Python Packages

When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

  • revoscalepy – This Microsoft Python package is used for remote compute contexts, streaming, parallel execution of rx functions for data import and transformation, modeling, visualization, and analysis.
  • microsoftml – This is another Microsoft Python package which adds machine learning algorithms in Python.
  • Anaconda 4.2 – Anaconda is an opensource Python package

Top 5 New Features of Oracle 18c Database

Any of the developments are fairly minor and incremental. For example, in previous versions of App Express, the end date within a range was removed from the list. In version 5.1, it is including with Oracle 18c, the range end date is included as it is with all other elements of Application Express. Now, version 5.1 also enables end-users to access their scheduling with the arrow keys on the keyboard, an update to the interface that is tiny but usefully intuitive.
In the updated Oracle, other improvements are more important and can have a greater impact on your everyday operations. These five impacts us as has been the most important.

Integration with Microsoft Active Directory
The database will authenticate and authorize users from Microsoft’s Active Directory, beginning with Oracle 18c, without any intermediate directories being needed.
This is a modern, easier way for Active Directory to integrate. Intermediary software such as Oracle Enterprise Public Participation was needed in previous versions to achieve integration.
This new function is called Centrally Managed Users (CMU) and allows you to manage Oracle application access authorization for Active Directory users. When clients are authenticated in this way, Active Directory account policies are implemented by the Oracle database.
Schema Only Accounts
In the past, as a user profile that held certain objects, a schema could be linked more closely. But this also meant that a user could log in and have control over all artifacts in the schema.
With schema accounts only, clients are still unable to login to the schema directly. These kinds of profiles can be developed without a password and, much like a normal user profile, allowances or tasks can be allocated.
Server Draining Ahead of Planned Maintenance
The database will now fail over the sessions to another service or node in a RAC area, Oracle 18c. For example, if a service is transferred to another node, the database labels existing drainage sessions so that the application is not disturbed. Any new sessions will be guided to another usable operating service.
The database uses a collection of rules to assess the end of a session and can be deleted from the server. These rules include custom SQL link checks and access limits where no request is active or operation is finished and the session has one or more recoverable states that can be reconstructed during failover.
Automatic In-Memory
As a manner to improve performance by maintaining columnar-compressed database segments in storage, Oracle In-Memory was implemented in version 12c. In 18c, Oracle promotes in-memory development by introducing Automatic In-memory (AIM). By creating a heat map of the in-memory enabled items, Target operates and creates opportunities for more commonly used applications objects. Only when there isn’t enough space to add another item to the memory store will Goal kick in.
SQL Cancel
In previous versions of Oracle, it was determined to destroy the session that was operating SQL if a database administrator tried to cancel a SQL query. This meant the session had to be removed from the database and a new connection had to be started. In Oracle 18c, the SQL statement itself can now be deleted and scaled back.
