SAP HANA In Memory Strategy

SAP HANA has many processes running on the SUSE Linux Server. SUSE Linux server manages the reservation of memory to all process.

 When SAP HANA starts up, Linux OS reserves memory for the program code, program stack, and static data. OS can dynamically reserve additional data memory upon request from the SAP HANA Server.

 SAP HANA create a memory pool for managing and tracking the consumption of memory. The memory pool is used to store all the in-memory data and system tables, thread stack, temporary computations and all other data structure required for managing the database.


When more memory is required for table growth or temporary computations, the SAP HANA memory manager obtains this from the pool.
For an overview, check out the Memory Overview feature of the SAP HANA studio. To access it, right-click on a System ->Configuration and Monitoring -> Open Memory Overview in the context menu, as follows:

The Imperial Valley of the Sonoran desert in southern California has been converted into a green patch which yields crops all the year round. Forests are not to be considered merely as a direct source of wealth; they are to be considered in relation to the national economy and geography. Forests serve many purposes. They hold together the soil and prevent or minimize soil erosion. The oxygen in the air is replenished by forests and plankton in the sea. Trees and plants, during photosynthesis, absorb carbon dioxide and release oxygen. Scientists fear that if forests are destroyed indiscriminately, there will be an increase in carbon dioxide and eventually the sun's rays will become hotter, the polar caps will melt and the ocean level rise and submerge much of our land. Vegetable mould that forests supply increases the fe...

The importance of water

Introduction  Life, both animal and plant, is impossible without water. Without water men die of dehydration About 70% of the human body is water. Of the total surface of the earth, 75 % is water and just below the surface of the land in most areas there is a saturated layer known as the water table. Animals and plants have large percentages of water in their make-up and some animals regulate their movements according to the water sources. Water: If there is no water there can be no life. The moon is a sterile desert because there is no water in it. It is to be remembered that it was water that determined the location of human settlements and without the Nile the Egyptian Civilization would not have developed The Nile provided the Egyptians facilities for irrigation and transport. As Herodotus said, Egypt is the "Gift of the Nile". Importance of water: The urban man rarely thinks of the importance of water. When he needs water, all he has to do is to turn on the tap.
