Using Shared Memory in CE 7.1

[Former Member]

Hi,

With CE 7.1 SAP introduced a new SAP VM that supports "shared memory".

I wounder if this could be used by a developer like the shared memory in ABAP.

Our case is that we want to load a huge table from ERP and hold/cache it in RAM for a WebDynpro Java app.

However, as we are using 2 server nodes the data would be twice in RAM so it would be great to move the data into the shared memory of the NetWeaver instance.

Thomas Jung presents this issue in his nice blog on reading 1 million rows in 3 seconds for the ABAP world: [http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/10552] [original link is broken] [original link is broken] [original link is broken];

Do you know if this is possible with NetWeaver CE and Java/JEE, e.g. declaring a class as part of shared memory and using a static field for the data?

Thanks for any hints.

Hi Kilian,

Shared Memory is used internally. If you need share data between many servers/nodes without replication, maybe a good solution can be the use of a Cache Solution like Terracota, JBoss Cache, Memcached
