Como você pode lidar com tarefas de administração de banco de dados em um ambiente de equipe?

As a member of a DBA shared services team with 18 DBA's, I believe that having clear SOP's, rules and processes is essential for our work. We know how to escalate issues in a timely manner and avoid unnecessary delays. We also focus on automating repetitive tasks, documenting our work and standardizing our troubleshooting guide to ensure smooth handling of database administrative tasks in a team environment.

If you are managing a team of DBAs working 24/7 I would focus on 1) Process to investigate and resolve issue 2) Use tools for schedule shifts, and tickets for work and ensure it's used properly 3) Configuration and documentation of all database and application dependencies. 4) Training of DBA on business and technology updates. 5) Ensure knowledge transfer happens to new joiners and trained about process, people, and culture. 6) Have juniors and train them to ensure you have people to cover shifts and not over-burned people to work on holidays. 7) Have a budget and time for recognition, awards, and team outings. Ensure efforts are recognized by management, application team, and customers.

No, you don't need a large team to manage a large set of databases. You only need 3-4 very skilled dba's who are not foul of miner tasks as backups, but those few skilled dba's should be able to script and automate as much as possible. The text at the left looks like it is written bij some AI framework. If the workload for the 3-4 very skilled dba's becomes too big too handle themselves - they should describe exactly what needs to be done from A - Z by extra resources. But 3-4 very skilled dba's are able to manage a very large environment. Off course very-skilled dba's are expensive what did anyone expect. If yoy pay peanuts you get monkeys. Oh yes and there is the holy grail of segregation of duties. Fed up playing for now.

Let’s be honest right from the start here. A DBA’s job is to be a Database Administrator, not a pie splitter. I wouldn’t allow a Developer to breath on a database of mine, let alone give them access to decide themselves, that’s what Test/Dev is for. A skilled DBA can juggle many tasks but a skilled management will realise the efforts and 24/7 nature of what a DBA role entails and reward the efforts.

Handling database administration tasks in a team environment requires coordination, collaboration, and effective communication among team members. Here are some best practices for managing database administration tasks in a team: 1. Define Roles and Responsibilities: 2. Team Collaboration: 3. Use Version Control: 4. Change Management: 5. Documentation: 6. Automation: 7. Monitoring and Alerting: 8. Incident Response: 9. Security: 10. Backups and Disaster Recovery: 11. Performance Optimization: 12. Training and Skill Development: 13. Communication: 14. Testing and Staging Environments: 15. Scalability Planning: 16. Audit and Compliance: 17. Rotation and Cross-Training:

Team works make the dream works. There are few simple steps which can work like magic. First: understand the strength and weaknesses of each team member and assign work accordingly. 2. Understand the responsibility of your team. If it is increasing and need more help, then hire to fulfil additional skillset or have team come up with ideas on how to handle by divide and conquer rule. 3. Documentation plays a key role in knowledge share to make sure you are not creating dependency on any team member. 4. Even though there is always assumed responsibilities in any work env, define them as you become aware of it. 5. Focus on making team efficient, remind everyone that there is no I in the team, have it integrated by using we when addressing team

Create runbooks for each database and assign SME and make him/her responsible for the maintenance activities like backups, patching, capacity planning and interaction with stake holders. Carve out a schedule for periodic activities. Document the day-to-day emails with stakeholders with proper ticketing system. Any unforeseen events/issues are to be documented along with proper RCA documentation to be shared in a repository. Hold weekly/bi-weekly catchup calls to make sure entire team is posted on the activities.

Clarity of work and yeah in task specially, building a small team who have good sound of it. Team must be know the impotency.

yeh - off course - but that is not the essence. As said - fed up of playing with texts written by an AI bot. I will ask ChatGPT to write my text. Oh yes - an essential part of the small team is that I am the primus inter pares. I will listen to my team members but if I feel not convinced about the approach to take it will be my call. But a golden rule is to use a test or sandbox environment to validate your thoughts or my thoughts before executing it on production. Oh yes documentation has the principal aim to make very skilled people redundant and pay peanuts to much less skilled people. With the best documentation a dba still needs to be able to interpret that documentation and sense if the documentation is not correct.

You need to be able to track all changes on your database in all environments. The 5W1H is a questioning approach and a problem-solving method that answers all the basic elements within a problem: what, who, when, where, why, and how. If you do not provide an infrastructure where you can get answers to all your questions, you may have many headaches in the future. DB versioning control is a must, otherwise, you may have to use DB compare tools, extending your deployment times until the morning.

I can speak from my own experience that Documenting beyond just DB design, config, usage, is valuable. Using Confluence docs to document things such as a list of SSRS reports that are scheduled, SQL Agent Jobs are that enabled and their schedule, AG Failover steps before and after, the list can be endless of what can be documented.

Version control is essential to DBAs. Github can be a great place to start not only for version control, but also for collaboration and project management and documentation. Documenting these changes and thought process with a properly executed Github workflow will save you big time along the way. Another tool I recommend that leans towards data modeling and architecture is dbdiagram.io Its a tool to visualize your design and collaborate with other team members on the same platform. It also support version control which is neat for this use case.

Version control is essential to rollback/improve/automate and having a shared repository control duplicate work and efforts. It also invites creativity to do something new rather than reinventing a wheel. Productivity lost occurs almost everyday due to duplicate work efforts. Tools can be used in effective way to reduce workload and create greater work life balance, which can strengthen the team and increase employee retention.

Another important step to handle database administration tasks in a team environment is to use version control and documentation tools to track and manage the changes and updates in the database schema, code, and configuration. This can help ensure consistency, quality, and reliability of the database and prevent errors and data loss. For example, you can use tools such as Git, Subversion, or Mercurial to store and manage the database scripts and files in a central repository. You can also use tools such as Markdown, Sphinx, or Jupyter to create and maintain documentation for the database design, functionality, and usage.

Database design itself should not belong to DBAs. All the scripts needed for maintenance could be well put in version control systems not just for accessibility but historical references as well (what changes in the system triggered particular scripts to be altered). Having these alone doesn't guarantee avoiding data loss directly, but can be a help with past examples in the restoration process.

It is rare, but it always happens, that we do not have a well-documented or version-controlled database environment. These are fundamental tools for a database administrator to ensure that the SGBDS are maintained in an organized, consistent and well-documented manner, facilitating development, maintenance and collaboration between team members.

Eis uma das tarefas mais importantes e maioria das vezes que recebe menos atenção. Utilizar softwares de versionamento como GitHub ajudam e muito, desde que utilizado de forma adequada ao ritmo do desenvolvimento e de forma homogênea entre todos do grupo. Se cada indivíduo faz de um jeito diferente, cria-se mais complexidade e não facilidade.

I agree. It is also possible to include some performance considerations in guidelines. Therefore, DBAs should hold courses that explain them in detail. For example, some SQL Server developers use multi-statement functions, which can mostly be replaced by inline functions. Or rely solely on Cursors, failing to use CTEs or recursive CTEs.

Defining guidelines and standards will ensure the service your team provides to your clients, internal or external, is consistent and efficient. These will allow for anyone on the team to address a request with confidence and agility. Also, provide an answer to the client that is well understood by all members on the team allowing anyone to take over the request at any time. Documentation is critical in this matter so that any new member could easily understand these standards and guidelines and ensure that they will persist in the long term.

No, follow best practices and they will contain of course standards and guidelines. Why should a successful team implement its own standards and guidelines.

Yes I agree with that. DBAs can write their own standards, and they must be also published to development teams. So to enforce security, what features are allowed or not (for example we don't allow database links), or for example to build new databases or servers. DBAs don't stay forever in a company and the next ones must have some documentation to guide them, at least at the beginning of their duties. We need standardized environments to be able to automatize/patch and have the same behavior from the databases.

Implementing standards and guidelines is fairly simple. Making sure the development teams respect and follow those standards is the hard part if you're a DBA working for an independent software vendor. Another thing that's impacted by communication, or lack thereof, between DBAs and developers is that, occasionally, developers might want to enable/change database or instance level configurations that would either affect performance or weaken security without first consulting with the DBA team.

In the collaboration with application and other administration teams, it is essential to get a proper handover documentation. Application development can be carried out by different parties (contractors, in-house dev teams) with unique set of rules and practices. A database administrator should make sure their team gets all information they need to keep the database performant, up and running all the time. They can, of course, give advices or guidelines when implementing a database structure based on their- or industry experiences, but again, a DBA is not a developer, therefore standard developer conventions don't matter.

This is a critical step no matter how small your team is. The need for someone else to be able to step in is always present and common practice at this point.

Databases have an important role in software engineering, they are easy to work with but must be designed efficiently. So database design must meet consistent rules.

É importante também estar atento e acessível a novas propostas sobre como lidar ou evoluir os métodos utilizados. Por exemplo, quando escutei em um forum de desenvolvimento de software vs acessibilidade para pessoas com déficit de visão, onde pedia-se “por favor não utilizem linha vazia de código como espaçador, atrapalha a leitura via OSR” tornou-se claro que perde-se oportunidade e velocidade se não houver consenso e acordo entre todos os envolvidos; afinal como no ditado “a capacidade de resistência de uma corrente é determinada pelo seu elo mais fraco”.

Automation is key to reducing the workload for monitoring and reducing resolution time. The use of scripting and other tools is a must-have skill for any DBA.

Automate comes after setting standards and guidelines and is a great way to ensure that these are implemented by default even for new members of the team that aren't familiarized with these standards yet. Testing this procedure is critical to guarantee efficiency and consistent times for completing a request.

Automation is the key to easy life and redundant work. Lots of operations like sessions or load monitoring or backup in database can be automated and monitored over logs or using apex application on your phone. If we talk about autonomous database there are so many PL/SQL APIs like scaling up and down cpus or transferring files to object storage which can help to automate your tasks.

The technology and tools being used plays a crucial role in the automation process and manageability. More a company invest in latest available tools and technologies, the more productive the DBAs are.

Any repetitive task is a chance to do something wrong, specially if that one is manually done. Don’t hesitate to automate that boring process. Technologies like ansible and Jenkins make things easier to reproduce and to follow up.

Ansible is useful for patching oracle databases. You are able to patch at night with no intervention, and some servers in parallel, yes for sure you need to test that in a non production environment.

For SQL Server, the dbatools PowerShell module is the most powerful free automation tool currently available. It's open source and it's actively maintained by highly knowledgeable members of the SQL Server community. With dbatools and a little PowerShell knowledge you can cover all the automation tasks you can think of, regardless of the size of your environment, including, but not limited to: - SQL Server instance deployments - backup test restores - migrations - patching - configuration changes - checking for configuration drift - copying databases, data, database or instance level objects across your entire environment

I find it is always helpful to go ahead and test it more than once. Use varying data allows more thorough testing and peace of mind.

Automation is one of the key factor in the database to reduce human error , automate the daily routine and time consuming task etc. , It also increases the productivity and efficiency of the resource, apart from Jenkins, ansible etc. we can also python & shell script for the automation too.

Automatizar é uma atitude excelente, desde que feita para o que realmente é repetitivo e com elementos fixos de entrada-saída. Caso contrário, gasta-se dias/meses criando e mantendo fluxos de automação que trazem ganhos mínimos para tarefas executadas manualmente em segundos em longos intervalos de tempo. Ou seja, deve-se equilibrar automação vs esforço. Outro fator importante, lembrar que será necessário manter e atualizar a automação a medida que os softwares evoluem, nada adianta ter uma automação maravilhosa a qual está defasada há anos.

SQL Server Profiler isn't as good of a tool as some people might think it is. It's resource-intensive, which is the last thing you would want on an already heavily used instance. There are far better options currently available either built into SQL Server like Extended Events, a lightweight performance monitoring system that uses minimal performance resources, or Query Store, which provides insight on query plan choice and performance for SQL Server, Azure SQL Database, Azure SQL Managed Instance. And there are tools built by community members that take advantage of SQL Server's existing performance metrics, like Brent Ozar's First Responder Kit, Erik Darling's sp_HumanEvents, or PSBlitz which I actively develop and maintain.

Since someone took a negative stand on SQL Profiler, I find that it's only "Resource Intensive" when used incorrectly by people that don't actually know the correct methods to use it. So, as with all else, I'll say "It Depends". To the other great point, I agree... there are a lot of incredible tools out there. When and how should you use them? Again, "It Depends". What that means is that you should actually know the server(s) and how SQL Server actually works before you do any "administration". A grand example of that is, do you actually know what's happening when you do Index Maintenance and why you might actually be crippling your server on the proverbial "morning after" or that you may be perpetuating Page Splits? Most, do not.

checking AWR report for each and every database without any performance issue is not a good approach, I believe a better approach to monitor the database performance is to check the alerts that the DBA usually receive and try to figure it out if anything they can do to resolve those alerts on a permanent basis, if possible and for other improvements in database a DBA can check the task which comes on a frequent basis like DB Refresh , cloning etc. and figure out a way how they can do it better , in a less no. Of time, without less chances of error etc.

It is often said that reviewing and monitoring database environments is the most assertive way of being proactive, without waiting for the customer to open a ticket or notify a problem to be resolved. These practices are essential to guarantee performance, availability, in addition to providing valuable information for planning and optimizing resources.

Keeping an eye on the database parameters requires an advanced monitoring tool. For one-off checks, standard SQL managers can be used, but for health checks, alerts and logging they are useless. Proper monitoring tools have database specific plugins which can be utilized to provide awareness and high availibility.

I know normally best add disk and Tempspace and also look the right sizing of the memory's sizing of the day thanks I know that right sizing of the size of filed Normally should be more a file and once done doing tde encryption and done and done thanks I know something done with stuff I end you settle the setup then when done the tde encryption that the best setup you once once completed you get it done completed sop and when do the tde encryption and settle follow the sop and settle it when it is done but follow the sop and do it asap as possible thanks

Agree But it is not straight forward Look the plan the transaction and see what can be done I know it is not not difficult to do at try I am also also applying for job if I can Look at the whole picture of you can thanks

To add to some of the great points in this article and to emphasize one in particular, proper communication is paramount. Every action should follow the same rules as those for teaching... 1. Let people know what your going to do (with enough warning for objections to be raised). 2. Do what you said. 3. Let people know what you just did.

It is highly recommended when you work alone, but in a shared environment, with several administrators, for me it is the first and main rule. Never ever use a graphical tool to change anything. All changes, even the simplest ones, should be made with a script that you can properly document and that helps you have a complete view of what you are doing. Using graphical tools may seem easier, but they are the gate to disaster.

In a team, I always strive for a structured and collaborative approach, so sharing knowledge through workshops, internal lectures, and documentation is one of the best practical ways to ensure business continuity and team satisfaction.

🤝 To effectively manage database administration tasks in a team, it is essential to define roles, foster open communication, and collaborate on challenging tasks. 📝 Thoroughly document processes and delegate effectively to empower team members. 📊 Utilize task management tools, 🔄 automate routine tasks, and encourage knowledge sharing. 🌱 Establishing a collaborative culture will enhance teamwork and ensure that database systems operate efficiently.

If a DBA team is doing their work properly, routine tasks will disappear or be outsourced to support teams. From that point, every experience will be unique and valuable for the whole team and future endevours. If you see you're doing the same thing every day, you may well be in the support team already.

I personally always join the provider's forum. Look for shared resources to take advantage of and minimize your efforts and maintenance.
