HANA Installation & upgrade

 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 deployments are characterized by multiple SAP HANA systems on one host. This configuration is approved for production environments as of SAP HANA Support Package Stack (SPS) 09. This is restricted to single host / scale-up scenarios only. Please keep in mind that multi-SID requires significant attention to various detailed tasks related to system administration and performance management

5.  



6.    Define additional properties, depending on which components are selected.

7.    After specifying all system properties, review the summary, and select y.

Next Steps

SAP HANA content that was installed as part of the SAP HANA database is updated automatically on tenant databases. Restarting the tenant databases is not necessary to trigger the deployment of the updated content on the tenant databases. You can monitor the progress of DU deployment by executing the following statement:

SELECT * FROM "PUBLIC"."M_SERVICE_THREADS" WHERE THREAD_TYPE = 'ImportOrUpdate Content';

Non-automated content and delivery units that were not installed together with the SAP HANA database and are not part of the SAP HANA database need to be updated manually on the database where the content was initially installed.

If your system is configured for system replication, you must perform the update on each host individually, starting with the secondary host. The version of the secondary system must be the same or higher as the one running on the primary system

Resident HDBLCM :

1)       Installing a Multiple-Host System

2)    Uninstall the SAP HANA System Using the Command-Line Interface

3)    Install &Uninstall SAP HANA Components Using the Command-Line Interface

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.

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, the logon w

SAP Startup Troubleshooting

  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 .

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 of Back-ups: 1.

SAP Kernel Upgrade in Distributed System

Image
What is the kernel of an SAP system? The kernel is a central program that acts as an interface between the SAP application and operating system. These files help startup the R/3 system, initialize the memory, create buffers and start managing the requests from users and effectively utilizing of hardware resources. The kernel is also responsible for starting and stopping all the application services like dispatcher, message server, collector, etc. Why Kernel Upgrade? SAP Kernel is the core of the application. Like all other applications, the Kernel contains the executable files (.EXE files for stating various processes in SAP). The Kernel is the heart of the operating system. It contains those files which are used to run every event in SAP. E.g.|: starting database, shutdowns of the database, starting sap, shutdown of sap, saposcol, to uncar the sap files etc. That's the reason why when a Kernel upgrade is done it means new versions of the various EXE files replace the older version

Set Up SAP HANA System Replication with hdbnsutil

Image
  Procedure:                                               SITE -A Enable system replication on the primary system(SITE A) as follows: In the Administration editor of SAP HANA studio, choose the  Configuration  tab and ensure that  log_mode  is set to "normal" in the  persistence  section of the  global.ini  file. Log mode  normal  means that log segments must be backed up. Log mode  overwrite  means log segments are freed by the savepoint (therefore only useful for test installations without backup and recovery). Do an initial data backup or create a storage snapshot. In multiple-container systems, the system database and all tenant databases must be backed up. As  <sid>adm  on the command line enable the primary for system replication and give it a logical name with the following command. The primary system must be online at this time: cd /usr/sap/<sid>/HDB<instancenr>/exe hdbnsutil -sr_enable --name=SITEA To check if the site has been successfully enable

Client copy means " transferring client-specific data"  within the same instance(SID) or between different instances(SID). Client copy can be performed with three different methods - Local client copy. Local client copy. Remote client copy. Client Import/Export. Prerequisites : Disconnect and lock dialog users. Suspend background jobs : This can be done using the report BTCTRNS1. The jobs will be released afterward using the report BTCTRNS2. Client Space check by using the report "RSSPACECHECK" in SE38. 1. Local Client Copy A local client copy copies between clients within the same SAP system. The local client copy must be initiated from the target client. The steps to perform a local client copy: Create an entry for the target client in the client maintenance table, choose transaction  SCC4 . In this example, client 101 will be created: Log on to the target client (client 101) as  SAP*  with the initial password pass (The user SAP* with the password pass is only ac
