Max no. of Webi services possible on a single physical server

[former_member205194]

Hi All,

We have been facing the below errors -

1) The Web Intelligence server is busy. Please save any pending change and try again later. If the problem persists, contact your BusinessObjects administrator. (Error: ERR_WIS_30284)

2) The Web Intelligence server memory is full. Please log off and try to connect later. If the problem persists, contact your Business Objects administrator. (WIS 30280)

Our reports are very very complex and seem to be crossing the memory limits (Upper Memory Threshold =1500MB/Max Memory Threshold=1800MB)

Testing done from our end : We scheduled a very complex report, retreiving huge data, every 3 mins (scheduled a particular Webi Processing server)

Observations :

1) The first 4 instances of CST-2203 report ran successfully.

2) 5^th instance failed with following error message:

The Web Intelligence server is busy. Please save any pending change and try again later. If the problem persists, contact your BusinessObjects administrator. (Error: ERR_WIS_30284)

3) 6^th & 7^th instance also failed but the error message was:

The Web Intelligence server memory is full. Please log off and try to connect later. If the problem persists, contact your Business Objects administrator. (WIS 30280)

We went through quite a few SAP notes, specifically-

1482911 - talks about increasing Webi servers and reducing idle connection timeouts

1297195 - reducing connection limit, idle timeout, Adding Webi servers and hardware

Can you please help me understand the max no of Webi servers I can have on a single machine? (currently we have 4 webi services)

BO server specs :

-Microsoft Windows Server 2003 Enterprise x64 Edition Service pack 2

-No of CPU cores : 16

-RAM : 32 GB

-BOE XI 3.1 SP4 FP 4.2

-Physical servers

-We have 2 physical servers with BOE installed, 2 Weblogic 10.3.2 servers, Oracle 10.2.0.4.0 Repository DB,

-2 CMS services (1 on each server)

-2 IFRS and 2OFRS(1 on each server)

-4 Adaptive Job server(2 on each server)

-8 Webi servers (4 on each server)

Please let me know if in case any queries/clarifications.

Thanks,

hi Monish,

It is recommeded to have one webi server per core, in this case you have 16 CPU cores/ node (I am guessing) and can have as many as 16 webi servers.

Thanks Peter, could you share any documents/SAP Note/KBA stating the same, if possible ?

If you using BO 4.x then there no need to keep many webi services in a single host. It is not recommended as well by SAP.

In 3.1 we can keep many as its a 32bit architecture and uses a max ~2G memory per service..

However in 4.X There is no need to keep 16 webi services in a single box.

As 4.X using 64 architecture you can keep a max of 2 services in a box. These services can use all the available memory.

Share the same memory for these two services. (2*16G=32G)

Keeping the number 2 because of considering failover situation

Thanks Ajay & Viswanadh for your inputs.

1) Actually, my initial question was for BOE XI R3.1. Peter's post above says that for 3.1 we can have one webi server per core. Do we have any documentation for this ? I understand that 3.1 is out of support, but would be great for anyone of you can share documents for 3.1 ?

2) Talking about BI4.1, you mentioned that we can keep 2 WIPS in a single box & that they would use all the available services.

If we are keeping 4 WIPS on a single box,

- How much memory a single WIPS can/will utilize ? (I believe it will depend on memory threshold setting)

- In that case, what should we keep the value of "Max/Upper/Lower Memory Thresholds" ?

Thanks for your inputs.

Monish
