What to do when end users complain that login to SAP system is taking more time ?

Network Connectivity: Verify the network connectivity between the user's workstation and the SAP server. Check for any network issues or latency that may be causing delays in the login process.


Ping Test: Open the command prompt or terminal on the user's workstation and execute a ping command to the SAP server's IP address or hostname. For example, enter ping <SAP server IP address/hostname> and observe the response times. A high response time or packet loss indicates network connectivity issues.

e.g. : ping <app server name>

Traceroute: Use the traceroute command to trace the network path between the user's workstation and the SAP server. In the command prompt or terminal, enter tracert <SAP server IP address/hostname> to see the hop-by-hop route and response times. Look for any delays or timeouts at specific hops.

e.g. tracert <app server name>

Network Monitoring Tools: Utilize network monitoring tools to monitor network performance and identify potential issues. Tools like Wireshark or PRTG Network Monitor can capture and analyze network traffic, helping you detect any latency or bottlenecks.

Bandwidth Test: Conduct a bandwidth test between the user's workstation and the SAP server. Various online speed test tools are available that can measure upload and download speeds. Ensure that the network bandwidth meets the required specifications for smooth communication.

or check with your Network Team

Firewall and Proxy Settings: Verify the firewall and proxy settings on both the user's workstation and the SAP server. Check if any rules or configurations are blocking or limiting network connectivity. Adjust firewall rules or proxy settings as necessary.

This is something your Network team or Server Admin team can help with

VPN Connectivity: If the user's workstation connects to the SAP server via a virtual private network (VPN), verify the VPN connectivity and settings. Ensure that the VPN connection is stable and not causing any delays in network communication.

To investigate login delays in the SAP system for a specific user, log in yourself to check if the issue is user-specific. Compare the login experience with other users to identify any discrepancies. Verify the user's account details and analyze their login history. Assess the user's workstation and configuration for potential local issues. If the problem persists, enable error logging and seek support from SAP. This approach helps pinpoint the cause of the login delays and directs troubleshooting efforts effectively.
Network Infrastructure Check: Collaborate with your network team or IT department to review the network infrastructure. Assess routers, switches, cables, and other network devices for potential issues. They can perform tests, such as link quality testing, to identify any problems.

Network Latency Measurements: Use tools like pingplotter or iperf to measure network latency, jitter, and packet loss. These tools provide detailed insights into network performance and can help pinpoint areas causing delays.


SAP System Performance: Examine the overall performance of the SAP system. High system load or resource constraints, such as CPU or memory usage, can slow down the login process. Monitor the system performance using transaction ST06 (Operating System Monitor) or similar tools.


High System Load: A high system load can affect login performance. Monitor the workload of the SAP system by analyzing factors such as CPU utilization, memory consumption, and disk I/O. Transaction ST06, also known as the Operating System Monitor, provides insights into system resource usage.

CPU Utilization: Check the CPU usage of the application servers to identify if they are heavily loaded. High CPU utilization may indicate a need for additional server resources or optimizations. You can also check the programs that are using high CPU using ST03N

Memory Consumption: Examine the memory utilization of the SAP system. Insufficient memory can lead to slow response times. Monitor the available memory, swap space, and buffer sizes to ensure optimal performance. Transaction code that you can use is ST02

Disk I/O: Analyze disk I/O operations to identify any bottlenecks that may impact login performance. High disk read/write activity can slow down the system. Consider optimizing disk access or upgrading hardware if necessary. 

Utilize transaction ST06 to access detailed system monitoring information. This tool provides a comprehensive overview of the SAP system's performance metrics, including CPU, memory, and disk usage.

Memory Utilization: ST06 provides information on memory consumption, including shared memory and heap memory. Check if memory usage is within acceptable limits and consider adjusting memory parameters if required.

CPU Time Breakdown: Transaction ST06 offers insights into how the CPU time is distributed across different SAP work processes, such as dialog, background, or update processes. Identify any imbalances or excessive CPU consumption in specific work processes.

Disk Utilization: The disk utilization section in ST06 displays disk I/O activity, including read and write operations. Identify any high disk I/O activity or potential disk bottlenecks that may affect login performance.

Work Process Analysis: Analyze the workload distribution among work processes using transaction SM50. This transaction provides an overview of active work processes and their status. Look for any long-running or stuck processes that may impact system performance and login times.

System Monitoring Tools: Besides transaction ST06, consider using additional system monitoring tools like SAP Solution Manager or third-party performance monitoring tools. These tools offer more in-depth performance analysis and monitoring capabilities to identify and resolve system performance issues.

E.g :Splunk

If high system load or resource constraints are identified during the performance analysis, consider the following actions:

  •         Hardware Upgrades: Evaluate the hardware infrastructure to ensure it meets the system requirements. If necessary, consider upgrading hardware components such as CPUs, memory, or disk storage to improve system performance.

  •         System Tuning: Optimize system parameters and configurations to enhance performance. Work closely with Senior BASIS administrators to adjust SAP profile parameters, buffer sizes, or parallel processing settings based on the system's requirements and workload.

  • Memory Parameters: Parameters like abap/heap_area_dia and abap/heap_area_nondia control the size of memory areas allocated for different types of work processes. Adjusting these parameters can ensure sufficient memory allocation based on workload patterns.

  • Parallel Processing Parameters: Parameters like rdisp/max_comm_entries and rdisp/max_wp_count determine the degree of parallel processing in SAP. Optimizing these parameters can enhance system responsiveness and improve processing efficiency for parallelizable tasks.

  • I/O and Database Parameters: Parameters like rsdb/max_blocking_factor and rsdb/ntab/entrycount can be adjusted to optimize database access and I/O operations. Properly configuring these parameters can minimize disk I/O bottlenecks and improve overall system performance.

  •         Performance Testing: Conduct performance testing to identify potential bottlenecks or areas for improvement. Simulate high load scenarios and analyze system behavior to optimize performance.


Check user Master Data: Check the user master data in SAP to ensure there are no issues or inconsistencies. Verify that the user's profile, authorizations, and roles are correctly assigned and up to date.

SAP Application Server: Analyze the performance of the application server where the user is logging in. Look for any bottlenecks or issues that may be affecting the login process, such as high response times or long database access times.

Single Sign-On (SSO) Configuration: If you have SSO configured in your SAP environment, verify the SSO configuration settings. Incorrect configuration can cause delays in the login process.

Network Bandwidth: Assess the network bandwidth between the user's workstation and the SAP server. Insufficient bandwidth can lead to slow login times. Consider any network congestion or limitations that may impact the login process.

SAP System Logs: Review the system logs, such as the SAP system log (transaction SM21) and the application server logs (transaction SM50), for any error messages or warnings related to the login process. These logs may provide valuable insights into the cause of the delay.

Load Balancing: If load balancing is implemented in your SAP system, check the load distribution among application servers. Imbalanced server loads can result in slow login times. Adjust the load balancing configuration if necessary. Transaction to be used here is SMLG 

Hardware or Infrastructure Issues: Evaluate the underlying hardware and infrastructure components of your SAP system. Ensure that servers, storage, and network devices are functioning optimally and meet the system requirements.

If all this does not work you can surely do as ChatGPT says :

"When code goes awry, seek wisdom from the senior sages or unleash the mighty power of SAP support!"

Here is a checklist that can be used :-

Network Connectivity




Verify network connectivity between the user's workstation and the SAP server.



Perform ping tests to check response times and packet loss.



Use traceroute to trace the network path and identify delays.



Identify any network congestion or limitations affecting login.

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

ST03N : The chapter for all BASIS Admins

This blog is targeted to BASIS ADMINS Transaction for workload analysis statistical data changed over time are monitored using transaction code ST03 , now ST03N (from SAP R/3 4.6C) . With SAP Web AS 6.4 the transaction ST03 is available again. From time to time ST03 and ST03N has seen many changes but later in SAP NW7.0 ST03N has reworked in detail specially processing time is now shown in separate column. Main Use of ST03N  is to get detailed information on performance of any ABAP based SAP system. Workload monitor analyzes the statistical data originally collected by kernel. You can compare or analyze the performance of a single application server or multiple application server. Using this you start checking from the entire system and finding your way to that one application server and narrowing down to exact issue. By Default :- You see data of current day as default view , you can change the default view. Source of the image : sap-perf.ca Let's discuss the WORKLOAD MONITOR By D

HANA hdbuserstore

The hdbuserstore (hana secure user store) is a tool which comes as an executable with the SAP Hana Client package. This secure user store allows you to store SAP HANA connection information, including user passwords, securely on clients. With the help of secure store, the client applications can connect to SAP HANA without the user having to enter host name or logon credentials. You can also use the secure store to configure failover support for application servers in a 3-tier scenario (for example, SAP Business Warehouse) by storing a list of all the hosts that the application server can connect to. To access the system using secure store, there are two connect options: (1)key and (2)virtualHostName. key is the hdbuserstore key that you use to connect to SAP HANA, while virtualHostName specifies the virtual host name. This option allows you to change where the hdbuserstore searches for the data and key files. Note

ABAP Dumps Analysis

Ever now and then have you heard about ABAP Dumps, We also have a joke everything in temporary in life except ABAP dumps for SAP Consultants. Lets try to understand ABAP dumps from perspective of a SAP BASIS Consultant. Dumps happen when an ABAP program runs and something goes wrong that cannot be handled by the program We have two broad categories of Dumps , In custom program Dumps and SAP provided program Dumps. Dumps that happen in the customer namespace ranges (i.e. own-developed code) or known as Custom Program , can usually be fixed by the ABAP programmer of your team. Dumps that happen in SAP standard code probably need a fix from SAP. You do not have to be an "ABAPer" in order to resolve ABAP dump issues. The common way to deal with them is to look up in ST22 How to correct the error ? Hints are given for the keywords that may be used to search on the note system. Gather Information about the issue  Go to System > Status and Check the Basis SP level as well as info

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. You can set

SAP system migration blog series - part 1: migration overview

Summary : This blog is part 1 of the blog series on SAP system migration. In this blog, we will provide overview about SAP migration, types of migration, their differences and usage scenario. SAP migration overview :   As the Greek philosopher, Heraclitus, said: “change is the only constant.” Same goes within SAP world too, often customer have to change the SAP systems along with its underlying components to meet the changing requirements, be it change from old hardware to new one, changing operating system, database. This change in SAP system components (DB, OS or Hardware) is termed as migration. Before we go into details of migration, let’s understand architecture of a typical SAP system.   An SAP system consist of SAP application instances, running on database (DB), hosted on operating system (OS), provisioned on hardware. Change in any one or more of these underlying components (DB, OS or hardware) warrant us to perform migration. Types of migration:   Broadly, there are two types
