SAP liveCache Technology

The SAP liveCache technology is an object-based enhancement of the SAP MaxDB database system. It was developed for managing complex objects in applications in which large quantities of data must be constantly available and changeable. You can only use SAP liveCache technology with SAP applications.

Properties of an SAP application with SAP liveCache technology:

  • With optimal configuration, all application data and objects are located in the working memory
  • Multiple application servers are sharing the read/write cache
  • Relational and object-oriented data modelling
  • Data-intensive business logic is executed close to the application data (minimizing round trips)
  • All database functions are available

SAP_livecache_technology

SAP liveCache Technology: Technical System Landscape:

In addition to the SAP MaxDB database kernel which provides basic database functions such as saving, restoring, and transaction management, an SAP liveCache database instance also comprises the following software layers:

  • SAP liveCache Applications (LCApps)

    The business logic is included in the SAP liveCache kernel by using DB procedures (stored procedures). This removes much of the work that would otherwise be needed for communication and the transfer of data.

  • Object Management System (OMS)

    A large part of the application data in an SAP liveCache database instance is managed in objects (OMS data). OMS data is managed in containers that are assigned to a persistent C++ class of the object type as object memory.

Java node not coming up,dispatcher and SDM is running

Problem statement:

We have enabled the debug port as per the client requirement. This enabling the debug port, system need to be restarted for this get into effect. After the restart 2 java node not coming up out of three nodes,dispatcher and SDM is up and running fine.

Solution:

Example screen shorts of before restart:

Before restart_Debug mode disabled

You can able to see that the debug mode is disabled.

Step 1: SAP standard information for your reference.

Portal std port number-5-system number-portocol port[EX: 53000] if it’s https connection use [53001].

Debug std port number-5-system number-start with 21.[EX: 53021].

Step 2: We have given the same debug  port number for all the three java nodes. So here FCFS concepts working,only one java node is capable for working,rest of two java node don’t have any other port number. so the result is java node went down.

Step 3: Go to config tool [EX:G:\usr\sap\SID\JC30\j2ee\configtool.bat].

Step 4:Two possible method to declare the debug port :

   1. Global Server Configuration[ We can declare the port number as a global value]

2.Instance Configuration [ Need to declare each and every instance]. PFB for your quick reference.

Config Tool

Step 5: In this case we have 3 java nodes, obviously we can choose the option two.

We have given the three port number as Node 1=53021

Node 2=53026

Node 3 =53031

PFB for your reference:
