How to properly Start/Stop SAP system through command line ?

Starting/stopping an SAP system is not a critical task, but the method that most of us follow to achieve this is sometimes wrong. A common mistake that most of the SAP admins do is, making use of the 'startsap' and 'stopsap' commands for starting/stopping the system. These commands got deprecated in 2015 because the scripts were not being maintained anymore and SAP recommends not to use them as many people have faced errors while executing those scripts. For more info and the bugs in scripts, you can check the sap note 809477. These scripts are not available in kernel version 7.73 and later. So if these are not the correct commands, then how to start/stop the sap system? In this post, we will see how to do it in the correct way. SAP SYSTEM VS INSTANCE In SAP, an instance is a group of resources such as memory, work processes and so on, usually in support of a single application server or database server with...

KPIs for Recovery in HANA Database Administration

Introduction: In the dynamic landscape of database administration, ensuring the robustness of a system is paramount. One crucial aspect that demands meticulous attention is the recovery process following a system failure. Two key performance indicators (KPIs) stand out in this realm – Recovery Point Objective (RPO) and Recovery Time Objective (RTO) . In this technical blog, we will delve into the significance of these KPIs for HANA database administrators and explore strategies to optimize them. Recovery Point Objective (RPO): RPO is a critical metric that defines the maximum acceptable data loss in the event of a system failure . For HANA database administrators, establishing an RPO involves a careful balance between data consistency and the overhead of continuous data replication. Continuous Data Backups: To meet stringent RPO requirements, implementing continuous data backups is imperative. Utilizing HANA's native backup capabilities and integrating them with a robust backup s...

Huge Multiversion Concurrency Control (MVCC) Versions in HANA

What is MVCC? MVCC is a database concurrency control method that allows multiple transactions to occur concurrently without conflicting with each other. In a nutshell, it ensures that each transaction sees a snapshot of the database at a specific point in time, even if other transactions are making changes concurrently. MVCC in SAP HANA: SAP HANA uses MVCC to manage concurrent access to data. Each transaction in HANA sees a consistent snapshot of the data at the time the transaction began. This is achieved by maintaining multiple versions of a data row, each associated with a specific transaction or point in time. The Issue of Huge MVCC Versions: Now, the term "Huge MVCC Versions" indicates a situation where there is a significant number of these versions for a particular set of data. Here's why this might become a problem: Increased Memory Usage: Each version of a data row consumes memory. As the number of versions increases, the overall memory consumption by the databas...

Execute HANASitter for hang situation analysis

The SAP HANAsitter is configured to perform default checks once every hour to ascertain the online and primary status of SAP HANA. Upon confirmation, it initiates tracking procedures, which involve regular responsiveness assessments (typically every minute). If SAP HANA becomes unresponsive, the HANAsitter commences recording activities, potentially capturing call stacks of active threads, run-time dumps, index server gstacks, and/or kernel profiler traces, although, by default, no recording occurs. When SAP HANA is responsive, the script scrutinizes critical features, including a standard check for more than 30 active threads. If this threshold is exceeded, the script triggers recording. Upon completing the recording process, the script exits, with an option to be configured for restart using the command line. Setup Steps Overview: Begin by creating an SAP HANA user with the desired name (e.g., HANASITTER) and assign the CATALOG READ privilege to it. Establish a user key in the hdbuse...

Building the Foundation of the PO System: Architecture and some terminologies

1. Loosely Coupled and Tightly Coupled Services : Loosely Coupled Services : These services interact with each other with minimal dependencies. Changes in one service don't significantly impact others. Pros include flexibility, easier updates, and better scalability. A common example in PO is when a shipping service communicates with an inventory service. Changes in the inventory service won't necessarily disrupt shipping. Tightly Coupled Services : These services are interdependent, so changes in one service can affect others. While they might provide faster communication, they can be less flexible and harder to maintain. For example, tightly coupling an order processing service with a payment service means any change in payment could ripple to order processing. 2. SOA - Service-Oriented Architecture : SOA is an architectural approach where everything is treated as a service, encapsulating specific functionality. Service Orchestration Example (Banking Transaction) : Consider ...

Work Process and Memory Management in SAP

Let’s talk about the entire concepts that are related to memory when we talk about SAP Application. Starting with few basic terminologies, Local Memory : Local process memory, the operating system keeps the two allocation steps transparent. The operating system does the other tasks, such as reserving physical memory, loading and unloading virtual memory into and out of the main memory. Shared Memory : If several processes are to access the same memory area, the two allocation steps are not transparent. One object is created that represents the physical memory and can be used by various processes. The processes can map the object fully or partially into the address space. The way this is done varies from platform to platform. Memory mapped files, unnamed mapped files, and shared memory are used. Extended Memory : SAP extended memory is the core of the SAP memory management system. Each SAP work process has a part reserved in its virtual address space for extended memory...
