grigorian.tech is Vlad Grigorian’s personal technical notes site. The content explicitly describes the material as technical records “for my personal use,” with topics mainly focused on Oracle database, GoldenGate, Terraform, and Ansible. It is not a productized developer tool or SaaS, but rather a knowledge base of practical experience for Oracle DBAs and operations engineers.
The site covers a wide range of topics: Oracle RAC, Data Guard, RMAN backup and recovery, SQL tuning, auditing, data warehousing, SQL Server, as well as Oracle GoldenGate unidirectional/bidirectional replication, disaster recovery switchover, OCI deployment, Microservices testing, and more. The crawled content includes a fairly complete GoldenGate bidirectional Active-Active replication troubleshooting case, with extract, datapump, and replicat parameters, a design using odd/even sequences to avoid primary key conflicts, and analysis of errors such as ORA-00001, OGG-01296, and OGG-01668. This kind of material can be useful as a reference for real-world troubleshooting.
The content does not mention pricing, account systems, APIs, SDKs, or commercial support, so it should be regarded as a free public reference site. It also does not offer self-hosting in the conventional sense. However, the scripts, parameters, and lab steps described can be reproduced in users’ own Oracle/GoldenGate environments. The site mentions resources such as PDFs, screenshots, and compressed scripts, but does not specify a license, so it cannot be considered an open-source project.
Its main strength is that the content is highly practical, directly providing configuration snippets, SQL, logs, and troubleshooting approaches, making it suitable for experienced engineers who need to quickly diagnose similar issues. It also covers multiple key areas of the Oracle ecosystem. The downsides are that the site feels somewhat dated, with dense navigation and a less modern information architecture. Some cases are based on older environments such as Oracle 11gR2, so readers need to assess version compatibility themselves. In addition, there is no SLA, community, ticketing system, or systematic documentation maintenance process.
It is suitable for Oracle DBAs, GoldenGate replication maintenance engineers, database migration and disaster recovery engineers, and operations staff who want to automate Oracle environments with Ansible/Terraform. It is not suitable for users looking for low-code platforms, cloud IDEs, general-purpose SDKs, or commercial DevTools. There is no evidence in the source content regarding access from China, so it should be marked as unknown. If access is unstable, alternatives such as Oracle official documentation, Oracle Base, OraFAQ, and the official Ansible and Terraform documentation may be better starting points.
