Database administrator in Oracle Cloud database: Resources and tools

For nearly 40 years, numerous customers from around the world have relied on Oracle database technology to run their database applications. Today, Oracle brings to the cloud the speed, scalability, and reliability of this technology through a new DbaaS (Database as a Service). This new Oracle Database has full compatibility from entry-level to larger database workloads. It enables organizations to take advantage of all the features of an on-premises database development system in the cloud data, SME, and departmental applications as well as enterprise applications.

Oracle DBaaS is an Oracle Cloud service that provides a database in the cloud. Thus it is offering scalability and connectivity between known and anonymous devices. That's why Oracle DBaaS can serve to drive smart actions for B2B and B2C organizations. DBaaS is the future of the Oracle Cloud Technology. And it's some of the advantages and results that can be obtained with Oracle DBaaS are following.

Taking a backup and performing recovery becomes easy in Oracle Cloud environment, but DBA needs to monitor backup process and corruption of the database. Patching becomes easy but pre-checks and post-checks tasks are same here too but you need to perform these tasks using DBaaS tools like DBaaSCLI with DBPATCHM or RACCLI. Still, DBA needs to deployment and maintain disaster recovery plan and backup recovery using some different cloud tools. There is some extra work also DBA needs to do that is change firewall rules, maintain security lists, etc. As DBA you should be aware of risk of database is on public cloud then you should need to maintain more precaution steps of security.

Which is best cloud database is wide subject. We cannot provide more detail in this kind of single article. But I tried to give you short advise and tips using this article. Exclusive and professional remote Database services offered by Dbametrix with strong response time and high availability for important and critical Oracle databases. Expert remote dba team of Dbametrix is having wide experience to manage large and critical database with quick problem resolution.

The general idea behind cloud computing is that IT resources such as computing power, database services, applications, and storage are delivered by a service provider over the internet with pay-as-you-use pricing. Organizations are shifting to the cloud for many reasons, but the most prominent are the promise of cost reduction and improved scalability.

With database-as-a-service (DBaaS), some traditional DBA tasks will be managed by the cloud provider. DBaaS is a cloud computing managed-service offering that provides access to a database without requiring the set-up of physical hardware, the installation of software, or the configuration of the database. With DBaaS, many maintenance and administrative tasks are overseen by the service provider, freeing up users to quickly benefit from using the database.

With cloud databases, availability also can become less of a DBA concern because the cloud can replicate databases across multiple geographical locations. Keep in mind, too, that cloud DBaaS providers manage the maintenance, the upgrading, and the application of fix packs to the DBMS, a particularly time-consuming process most DBAs dislike. Nevertheless, DBAs still need to communicate with the DBaaS provider to know when maintenance is being applied and if there could be any impact that would need to be addressed.

Furthermore, the DBA team must comprehend the exact cloud services being provided and verify that they conform to its usage needs. For example, DBAs need to understand issues such as latency problems, size limitations, and any other considerations that change the way that an organization works with the database.

The DBA must also become a vital cog in the budget management process for the cloud database. Just because it is easy to scale up using cloud database services does not mean there is no cost. As a result, the organization needs an expert who understands the impact of additional workloads on the DBaaS contract. Moreover, the DBA must have knowledge of the impact of database and application design and architecture decisions and how they affect costs.

The Azure database administrator implements and manages the operational aspects of cloud-native and hybrid data platform solutions built with Microsoft SQL Server and Microsoft Azure Data Services. The Azure database administrator uses a variety of methods and tools to perform day-to-day operations, including applying knowledge of using T-SQL for administrative management purposes.

In your Appian cloud database, you can use schemas to control access to certain data. All Appian Cloud databases ship with a default "Appian" schema which has broad access. However, database administrators can create additional schemas and use system groups and object security to secure access to them.

Even though there may be no predefined limits (besides disk) to the amount of process data that can be stored in the Appian Cloud database, it is important to keep in mind that you might experience decreased query performance as disk footprint increases, unless you properly design the schema.

Because we want the Appian Cloud database to be easy to use, it is not a full-featured database solution. Many advanced features would require a dedicated database administrator for support. In order to avoid that, Appian Cloud customers don't have access to advanced database configurations.

If you are editing a stored procedure or function as a database administrator in phpMyAdmin, make sure that the value in the definer field is either empty or dbadmin.In general, it is a best practice not to use the DEFINER clause when running scripts in phpMyAdmin.

As a database administrator (DBA), you need to demonstrate your skills on a daily basis. However, if you have no formal training or certification, it can be challenging to land a new job or achieve an internal promotion.

Fortunately, there are various highly-regarded database certifications for the leading databases. Whether you work primarily with SQL or Oracle, you can use a prestigious certificate to increase your earning potential.

Database certification can demonstrate your skills as a proficient database administrator (DBA). Furthermore, a prestigious certificate could increase your job prospects or land you an internal promotion.

A third type of database administrator is the Application DBA. This role focuses specifically on integrating databases into the applications that use them. Navigating most databases usually requires knowledge of a specific type of query language. The most common is the Structured Query Language, or SQL. Most users will not learn how to use and navigate SQL; instead they will use a front end application to carry out the tasks required of them. In a commercial bank, this application is the banking software itself (the users are only able to access the database via an application, which ensures data security). It is the work of the application DBA to ensure that the database and the application using it communicate properly, and that accurate results are communicated between the two. For instance, when a user enters a customer name and clicks to display their bank account balance, the database returns the correct amount and not, say, the loan balance.

According to remuneration-tracker Payscale, the median base database administrator salary across the U.S. was $67,733 in 2015, or a base hourly rate of $22. However, this is simply a rough average, ranging from a starting salary in the low 40ks for an entry-level DBA position, to the high $200ks for an expert, senior database administrator in charge of multi-terabyte distributed databases for large corporations. These senior-level positions are far less likely to be concerned with the technical day-to-day aspects of database management. Instead, they are strategic-level senior management positions within the ICT department, and often head large, multi-site teams of DBAs. Nevertheless, most senior database managers begin their careers as techie DBAs, tinkering with and learning the various aspects of databases and database management.

There are two main paths to become a database administrator: Focusing on being a DBA from the beginning of an IT career, or (more commonly) starting in a general ICT field, such as helpdesk support or development, and gradually becoming more proficient in database administration.

As such, in order to determine how long it will take to become a database administrator, you need to look at the math. The assumptions below are very general database administrator education requirements for a rookie DBA, not for someone already working as a database administrator looking to switch database administration jobs:

This highlights another fact about the database administrator field: you will always be learning something new. The software and platforms are always changing. New non-relational databases, along with new versions of existing databases, create an ever-shifting landscape that can be difficult to navigate without constant education. At the same time, the database administration field encompasses so many other related areas of expertise within IT (such as systems administration, virtualization, networking, cloud computing, etc.), that database administrators find themselves constantly acquiring new nuggets of information throughout their careers.

Next, it is a good idea to get certified in one or more commercial database systems. Your college degree may have taught you the basics of database administration, and you may have even learned some SQL, but this is only an introduction. Most companies will focus on hiring people with certification and DBA training in the specific database software they use. Some of the big players and their database administrator certifications are:

A related and important skill for a database administrator is SQL tuning, or query optimization. This means creating SQL statements that place the minimum possible load on the database in terms of CPU, memory management and disk access. 2ff7e9595c
