Difference between system & server map

Hello All,

Need to know what’s the difference between system & server map, please explain with an example

What I understood is System is for workstations & Server map is for server only activities, why we go for server map when we have system , why 2 entries in some systems

Thanks in Advance!

Hi,

System = these are the OCM entries corresponding to users.
When they need to access a table or launch a process, they
will run and retrieve data according to System OCM entries.

Server Map = same for servers. When your server needs
to access a table or launch a process, it will run and
retrieve data according to its own Server Map OCM entry.

If you have N Enterprise Servers, you'll have 1 System
OCM and N Server Map OCMs.

Very good description. However, I want to point out that your last statement is not a hard and fast rule. I have designed system where I have enterprise servers share Server Maps.

Again, not a criticism, just wanted to point out that it can be designed otherwise and one should not think a system misconfigured if they find that it has multiple enterprise servers with a single server map.

Hi Brother of Karamazov :

Yes, you're right.
Just wanted to provide a quick and easy explanation.
Thanks for providing additional detail!

Thanks for the info, Appreciated!

System - a datasource which contains information about how the system is defined. All workstations use this as a bootstrap datasource (defined in their JDE.INI file). Contains OneWorld CNC specific definitions including OCM, Datasource Definitions, Printer Definitions, Security, OMW etc.

Servermap - a datasource that provides information about how the system is defined for server differences. A single servermap is require for each TYPE of server in the configuration. This can be viewed as a "subset" of the System Datasource that contain information that different Operating Systems from a FAT Client requires to connect in their own perspective.

A major difference, which explains why there is one System and different Server Maps is the F98611 - the Datasource Definition. An example is a database datasource for an AS400. The System Datasource would utilize JDBODBC.DLL for its connectivity (going through iSeries Access) - whereas the SAME EXACT datasource for the Server (the AS/400) would use "DBDR" to connect (direct connectivity).

Another example is the OCM. In the J environments, the default BSFN is mapped to the Enterprise Server, and overrides for specific business functions might map certain items to "LOCAL". The server map will ALWAYS run Business Functions "Locally" - so the same J environment mappings might not have any BSFN mappings at all, but would definitely NOT have something mapped to "LOCAL" (which is actually a FAT Client definition, not a server definition).

It is important that the System Tables and Server Map tables look somewhat similar, that they pretty much contain everything the enterprise needs to correctly operate.

In an example customer's site (taken directly from Configuration Planning and Setup) with 1 AS/400 and 1 HP9000 machine, there would be 1 System Datasource, and 2 Server Map datasources (one for the AS/400 and one for the HP9000). If an HP9000 was added to the architecture, a new Server Map would not need to be added - but if a new Intel Application Server is added, then a new server map would have to be created.

Hope that explains it all.

Thanks all for valuable information!
