Background Processing in SAP R/3

Programs can execute in the background of the SAP system while online operation is occurring. SAP's background processing system is easy to use and completely integrated within the system. Suppose a manager wants an accounting report ever Monday morning. Rather than having the manager execute this program online every Monday morning, it could be scheduled to run every Sunday night so that the report would already be printed for the manager when she arrived to work. This scheduling of a report program is accomplished with SAP' background processing system.

SAP R/3 System Profiles - Default Profile, Start Profile and Instance Profile

What are SAP Default, Start, Instance Profiles?

• Profiles contain parameters that specify how to startup an instance and how to setup the various variables that define the way the SAP instances and system work.
• Path: <SAPMNT>\<SID>\SYS\profile\
• Example:D:\usr\sap\DEV\SYS\profile\
• Only the Central Instance Host file system contains the profiles for all instances.
• Dialog/regular instance hosts do not have any profiles stored on them.
• If you have N instances on a SAP system (sharing the same SID) you will see 2*N+1 profiles files and their corresponding backup files if any in the SYS/profile folder.

Default Profile

Name: DEFAULT.PFL Contains global parameters that apply to all instances in the SAP R/3 SID such as:

SAPSYSTEMNAME = DEV
SAPDBHOST = CHALAKI
rdisp/mshost = CHALAKI
rdisp/sna_gateway = CHALAKI
rdisp/sna_gw_service = sapgw00
rslg/collect_daemon/listen_port = 37

Logon Load Balancing in SAP R/3, Logon Groups, SMLG and CCMS Configuration for Basis Admins

What is SAP Logon Load Balancing?

• SAP R/3 Logon load balancing enables a SAP Basis admin to create various log on groups.
• Logon groups are logical groups of users that can be assigned to one or more SAP instances.
• A group GroupX, Once assigned to an instance I, all users who login using that group in the SAP log on pad client, will automatically login into the instance.
• If you have two instances I1, I2 then you can create two groups GroupX and GroupY and assign them to I1 and I2 respectively. You can also divide your users according to some criterion (such as Floor1 thru 5 will use GroupX and floor 6 thru 10 will use GroupY) and ask them to use only those groups.
• In SAP Logon Pad, you can create and delete logon group entries, remove instances from groups, and delete entire logon groups.
• When you call transaction SMLG, the CCMS: Maintain Logon Groups screen shows a table with entries for logon groups and the associated instances. An entry in this table, which is characterized by an instance and a logon group, is known as an assignment.
• A logon group to which multiple instances belong therefore consists of multiple assignments in this table, where an assignment contains one instance in each case.
