Administración de bases de datos Jobs

La plataforma SoftGuard que administro dejó de conectarse a la base de datos SQL Server justo al momento de iniciar sesión; siempre devuelve “Tiempo de espera agotado”. Quiero que analices la infraestructura completa de SoftGuard y del motor SQL, identifiques la causa de la conexión fallida y la restaures sin afectar los datos ya existentes. Contexto – El fallo ocurre únicamente al loguearse; una vez que la aplicación supera ese punto (cuando lo logra en entornos de prueba) todo funciona. – Base de datos alojada en SQL Server; gestión habitual con SQL Server Management Studio. – No hay indicios de datos corruptos, por lo que el foco es la capa de conexión, autenticación, puertos o parámetr...

I want to watch a complete, real-time walkthrough of Oracle Database 19c patching and fresh installation, carried out on a running system while I ask questions as we go. Each step needs to be explained: pre-checks, backup strategy, patch download, opatch execution, post-patch verification, clean installation and initial configuration. Alongside the live screen-share session, I also need a polished recording of the same process (it can be the live session itself if the audio is clear), plus any command scripts or checklists you use so I can repeat everything on my own later. We will arrange at least one interactive meeting for Q&A, followed by delivery of the recording and support materials. Once I can reproduce the patching and install procedures without issues, the job is done.

I’m running a ZKtec Biotime deployment that has begun throwing software errors I can’t pin down. My immediate goal is to get the system fully stable again and understand the root cause of the bugs, whether they stem from the database, the Biotime service, or an interaction with the operating system. Here’s what I need from you: • Diagnose the recurring software errors in my current Biotime installation. • Apply fixes or patches to remove the bugs and restore normal operation. • Document what went wrong, how you resolved it, and any preventive steps I should take.

I have a web-based application almost ready to roll out; the only item still missing is a set of secure database access links that my front-end can call for standard user-login sessions. I need those links built, verified, and handed over together with any connection strings or tokens that go with them so that end-users can sign in without ever touching elevated credentials. What I expect from you • Create the actual database access URLs (or connection strings) configured strictly for user-level privileges. • Confirm they function end-to-end by testing a sample login flow against the live site. • Supply a short note or README explaining where each link should be placed in the codebase and how to rotate or revoke it if required. If you have experience hardening conn...

I need a Windows-based virtual machine spun up on Amazon Web Services and fully prepared for an Electronic Health Records (EHR) trial. I will provide the installer and licence keys; you bring the AWS know-how to choose the right instance type, harden the OS, open only the essential ports, and grant me full administrator access. Once the server is online, the EHR package must be installed, configured, and connected to its database engine (SQL Server Express is fine for now unless you advise otherwise). After installation, I want to walk through the application together, troubleshoot any performance or permission issues, and confirm that remote users can reach the live environment securely over HTTPS. If everything works well, I’m likely to need ad-hoc help down the road—patchi...

Every time I open VisionPoint to create a new purchase order, “ghost” line-items appear—records that were never added, don’t show on the printed PO, yet linger in the database and stop me from saving. The problem started the moment I tried entering a fresh purchase order and now happens on every single attempt. I need someone who knows their way around VisionPoint’s backend (tables, data integrity routines and any related SQL/Visual FoxPro utilities) to: • Locate the underlying cause of these ghost items. • Clean the current data so no phantom records remain. • Validate that new purchase orders save and print correctly without introducing more stray records. • Provide a brief summary of what was fixed so I can prevent a repeat. If ...

I have a fully-functional SQL Server database that currently sits as separate MDF and LDF files. My only goal is to turn this live set into a single, clean .BAK file that I can archive safely for future use. You can remote in or guide me through the process—whatever gets the job done quickly and without data loss.

I need an engineer who already knows their way around the API well enough to move beyond simple pulls and actually manipulate the data in-flight. My immediate objective is to ingest large streams of stock-market quotes, on-chain cryptocurrency metrics, and FRED macro-economic series, reshape them as needed, and then run clean Pearson correlation studies that I can query on demand. A working site is already created with NextJS/Supabase/Vercel, but I need help taking it to the next level and also hosting it in a budget friendly SQL provider. 2M+ rows of data. More details will be provided if interested. Looking to work with solo engineers not teams or agencies. Thank you!

I’m ready to move our data into a brand-new Azure SQL Database instance and need a seasoned SQL developer to take the lead from design through deployment. The job starts with a clean slate—no legacy SQL Server to worry about—so I want a solid, future-proof schema that follows best practices for normalization, indexing, and naming. Your work will cover: • Designing the database structure and providing the DDL scripts to create it in Azure SQL Database • Configuring the instance for performance, security, and scalability (firewall rules, Transparent Data Encryption, role-based access, automated backups, etc.) • Writing any necessary stored procedures, views, or functions to support day-to-day operations • Supplying clear documentation and a qu...

I have a sizeable MySQL database that needs to be turned into clear, decision-ready insights. The work begins with pulling the raw tables, writing efficient SQL queries, and cleaning or restructuring the data where necessary. Once the dataset is reliable, I’d like you to run deeper statistical analyses in Python (or Excel where it makes sense) to surface patterns, trends, and any significant correlations. The final step is to convert those findings into intuitive visuals and interactive reports in Power BI so my non-technical stakeholders can drill down by date, segment, and KPI without ever touching the underlying code. Deliverables I expect: • A cleaned, well-documented dataset (or SQL scripts) ready for downstream use • A concise statistical analysis report wi...

I have a PHP-based website that suddenly stopped talking to its MySQL database. Every page that relies on data now throws a connection error, so visitors see nothing but an ugly message. The rest of the codebase is stable; it’s purely the database hand-shake that’s broken. Your task is to dive into the existing PHP, identify why the connection fails, and deliver a clean, working fix. Once repaired, the site should load data normally without warnings or deprecated notices, and your solution must stay compatible with the current server stack (PHP 7.4 on Apache, MySQL 5.7). Deliverables • Updated PHP file(s) with the corrected connection logic • A short note outlining the root cause and the exact change made so I can maintain it later I can provide SSH or cP...

I need a robust, cloud-hosted database that can safely store and retrieve large volumes of transaction records for my application. At this stage I am still open to advice on whether a relational SQL solution or a NoSQL alternative will serve me better, so part of the job is to walk me through the trade-offs and recommend the architecture that best balances scalability, speed, and cost. Once the platform is agreed, I will look to you to design the schema (or data model), implement the database online, seed it with some sample data so I can run realistic tests, and deliver clear connection details for my dev team. Security best practices—encryption at rest and in transit, sensible indexing, parameterized queries or their equivalent—are essential. Deliverables • Technical...
