SAP Logon Configuration(Load Balancing)

Image
Logon groups (or work groups) are configured to dynamically distribute the load being processed by the dialog work processes. Setting up logon groups helps in uniform distribution of the work load across the available instances. While logging on using a logon group, the ABAP message server is contacted to identify the instance with best performance statistics within the selected logon group . A report runs in SAP every 5 minutes which determines the load across each server and updates in the memory area of the message server. This information will be used by SAP GUI to determine the best instance to distribute the next user.   SAP Logon Process Let’s start with discussing an overview of SAP Logon process. High-level understanding of the process will help to explain details of SAP Logon configuration. SAP Logon Process Overview When user(s) accessing SAP system via  SAP GUI , the request is forwarded into ABAP dispatcher for the direct logon. If SAP GUI is using logon group, th...

EHP Upgrade (SUM)

Image
  Introduction: SAP Technical Upgrade is a periodic project that is implemented across companies to upgrade their SAP system to the latest released version. Most of the upgrade activities are done by the technical team, and functional consultants' role is limited and mostly confined to regression testing. Reasons for SAP Technical Upgrade : Since technology and businesses evolve, companies need to maintain a technological infrastructure that can support that change. This is the major reason why companies should undertake a technical upgrade of their SAP system. Of course, there are many secondary reasons, the significant one being the fact that like all software vendors SAP supports a released version of its software only for a limited period. Now we can go through the detailed phases included in the SUM upgrade process. latest SPAM version and Kernal also considered prerequisites  Prerequisites : 1. Check SYSTEM user is De-active, if yes, it should be activated. Passwords f...

SAP Startup Troubleshooting

Image
  1. IS DATABASE UP AND RUNNING? This is an  absolute  prerequisite for SAP SYSTEM to start. In order to test this, operating system command  R3trans -d   can be executed (as SIDadm user). Any return code different than 0 means that DB cannot be reached by DIALOG work processes, and so SAP system will not initiate. The following return indicates that the database is up, running, and reachable by SAP work processes: <hostname>:SIDadm > R3trans -d This is R3trans version X.xx (release 742 - 18.11.14 - 20:14:09). unicode enabled version R3trans finished (0000). -->There is  NO POINT  in moving the analysis further while the return code is different than zero. --> In case the return code is different than zero, please involve your DBA/Network/OS teams. 2 . IS SAP STARTUP AGENT (SAPSTARTSRV) RUNNING? There must be  ONLY ONE  sapstartsrv process running for each instance. Examples for each platform below: Examples...

SAP Transport Management System (STMS)

TMS is used to move, manage and control copy development objects and customizing settings in an orderly fashion across SAP Landscape. STMS [SAP Transport Management System] Domain Controller–:  It is used to control the landscape. There will be only one domain controller in the landscape. Initially, it is set to development and later can be moved to on higher available system such as PRD/QAS/Pre7/ production but to keep things simple most of the cases we keep DEV as Domain Controller Member Systems–: The other systems are included in the domain referred to as member systems.  How to Configure   STMS Log on to the SAP system, which is decided to be the Domain Controller, in client  000  and enter the transaction code  STMS. If there is no Domain Controller already, a system will prompt you to create one. When the Transport Domain is created for the first time, the following activities happen in the background: Initiation of the Transport Domain / Landsc...

Hana Column and Row Store & Delta Merge Operation

Image
  Row Vs Column store : The SAP HANA database supports two types of table: store data either 1) column-wise (column tables) 2) row-wise (row tables). SAP HANA is optimized for column storage and this is the default table type. Conceptually, a database table is a two dimensional data structure with cells organized in rows and columns. Computer memory however is organized as a linear sequence. For storing a table in linear memory, two options can be chosen as shown below. A row store stores a sequence of records that contains the fields of one row in the table. In a column store, the entries of a column are stored in contiguous memory locations. Storage Type When to Use Column store Calculations are typically executed on individual or a small number of columns. The table is searched based on the values of a few columns. The table has a large number of columns . The table has a large number of rows and columnar operations are required (aggregate, scan, and so on ) High compression rat...

  Software Download: SAP HANA System Types : Ø   Single-host system - One  SAP HANA  instance on one host Ø   Multiple-host (distributed) system - Multiple  SAP HANA  instances distributed over multiple hosts, with one instance per host. SAP HANA Deployment Types : Tenant Databases : The tenant database deployment type makes it possible to run several SAP HANA instances on the same hardware in a production environment. Multiple Components on One Database (MCOD) : MCOD deployments are characterized by multiple applications on one SAP HANA system. SAP supports deploying and running multiple applications on a single SAP HANA production database  only  for packaged applications and scenarios listed on the "White List" included in SAP Note 1661202. Virtualized : SAP HANA systems can be run on virtual machines with restrictions to the hypervisor (including logical partitions). Multiple Components on One System (MCOS): MCOS...

SAP HANA Backup

Image
  SAP HANA Persistence To ensure optimal performance, the SAP HANA database holds most of its data in-memory. However, it still uses persistent storage to provide a fallback in case of failure.   During normal database operation, data is automatically saved from memory to disk at regular savepoints . Additionally, all data changes are recorded in the redo log . The redo log is saved from memory to disk with each committed database transaction. After a power failure , you can restart the database as you would with any disk-based database. It then returns to its last consistent state by replaying the redo log since the last savepoints . Although savepoints and log writing protect your data against power failures, savepoints do not help if the persistent storage itself is damaged . To protect against data loss because of disk failures, backups are required . Backups save the payload (the actual data) of the data area and log area to different locations.   Types o...
