Heap Size for the BI4.1 Servers

server administration XI Server Discussion

Dear Forum Members,

I would like to understand what the memory each of the servers take up in a default installation.

We only see sizing the APS and AJS, but I would like to know what the memory each of the other servers take, so as to calculate the amount of free RAM left on server. Can someone help me understand for the servers listed below(as available in BO BI4.1)?

AdaptiveJobServer(the xmx parameter is not available for this server. So does this mean it does not take any RAM capacity)?
AdaptiveProcessingServer(xmx is 8g, I understand the RAM for this server is 8G
CentralManagementServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
ConnectionServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
ConnectionServer32(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
CrystalReports2013ProcessingServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
CrystalReports2013ReportApplicationServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
CrystalReportsCacheServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
CrystalReportsProcessingServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
DashboardsCacheServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
DashboardsProcessingServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
EventServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
InputFileRepository(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
OutputFileRepository(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?
WebApplicationContainerServer(the xmx parameter in the properties of this server 2g)…So, the RAM for this is 2G?
WebIntelligenceProcessingServer(cannot find the xmx parameter in the properties of this server)…So, what is the RAM for this?

Can you please assist me on this?

Thanks.

I suggest you read a little more about the architecture.
https://bobj-board.org/t/202803/5

RAM assigned to the services will be dynamic depending on what activity is happening / what is being used.

It might help also, if you describe exactly what you are hoping to achieve.

I am trying to understand the minimum memory requirement for each of the Business Objets servers.

Please help me.

I don’t think waht you are asking for really exists.
You don’t “size” an installation that way.

A minimum hardware spec is a minimum hardware spec, in fact SAP state what the minimum spec is for running BO.

This is going to depend on how you use Business Objects. This is why conducting sizing is important. Every installation will be different.

For instance, we use Crystal Reports so we will need to look at the services that run Crystal Reports to determine what amount of memory we need to get good throughput and response. You may not use Crystal Reports at all so that doesn’t matter to you.

As another example, if you have mostly scheduled reports, then your job servers will need more memory. If you have mostly reports that are viewed on demand, then you processing servers will need more memory.

You need to look at the requirements for your services from the perspective of how you use Business Objects, not from a standard that has been generated by someone else for a system with different usage.

For Crystal look at the parameters for spawning servers.
For Webi Processing server look at the properties (scroll down in the CMC to the bottom of properties for Webi Proc server), there you can configure RAM usage.

Otherwise, please do read the admin manual available at help.SAP.com and the sizing guide here https://scn.sap.com/docs/DOC-33126

Sorry for not being clear about my query. What I want to understand is…We set the xmx parameter for the APS to limit the max memory that APS can take at any time. In the similar lines how do I understand the maximum memory that each of the BO servers(CMS, AJS, Webi Processing Server, Connection Server etc…) can use at any time?

Hope I have put my question clearly now.

Thanks.

You can only do this by observation. You have to monitor how much memory these processes use when you system is in use.

And as I said earlier, totally dynamic, so you need to look at peak usage to get any idea.
