1. The document describes how Oracle allocates CU blocks and CR blocks in the buffer cache when updating column values from A to I through consecutive commits.
2. It shows the expected outcome of 6 CR blocks being allocated for the 6 updates before a new CU block is needed.
3. An analysis using ODI Analyzer on an Oracle database shows this expected behavior occurring, with CR blocks 1-6 being allocated and reused for each update before a new CU block is created on the 7th update.
The document describes the Oracle undo segment and how it tracks changes to data in transactions.
1) It shows the initial state when a value of "A" is entered into a table column.
2) It then shows an update transaction that changes the value from "A" to "B", with the undo segment recording the before image of "A".
3) A second update transaction is shown, changing the value from "B" to "C", with the undo segment recording the before images of "B" and "A".
This document discusses transaction slot before-image chaining in Oracle databases. It begins with questions about cleanout, undo storage, and commit SCNs. It then describes the architecture of before-image chaining, where commit SCNs and other metadata are stored in undo blocks and transaction control blocks to link a transaction's multiple before-images together. Diagrams show how before-images are chained across multiple undo blocks using these references.
[ODI] chapter3 What is Max CR DBA(Max length)? EXEM
The document discusses how Oracle's buffer cache allocates consistent read (CR) blocks and current (CU) blocks when updating a single column value in a table multiple times with commits. It finds that with the parameter _db_block_max_cr_dba set to 6, Oracle allocates a new CU block for each update while reusing the first 6 CR blocks, allocating a new one for the 7th update. Screenshots from an internal tool show the state of blocks in the buffer cache after each update.
[ODI] chapter2 what is "undo record chaining"?EXEM
- Undo record chaining allows Oracle to rollback multiple transactions by linking undo records together in a chain.
- When an update is made, an undo record is generated and added to the undo block. A new record contains the before image of the update.
- Undo records for a transaction are chained together by transaction ID and sequence number. This allows Oracle to efficiently rollback a whole transaction by traversing the undo record chain.
[ODI] chapter1 When Update statement is executed, How does oracle undo work?EXEM
When an update statement is executed in Oracle, the undo mechanism works as follows:
1. Oracle generates a new change undo (CU) block in the buffer cache to track the before image of the updated row.
2. The original data block is copied to the new CU block, and the original block is marked as a change redo (CR) block.
3. Oracle allocates memory and assigns a transaction ID (XID) to the transaction in the V$TRANSACTION view, tracking the undo information for the update.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
