Dear experts,

I posted earlier in the same thread that we have split our APS into 3. We didnt have any problems with daily load as it is our POC box.

However, we are in the middle of performing some VST on our BO POC server and we notice that no matter how the load varied (in the high load range by chaging the number of concurrent users) the core APS (we have 3 APS instances, one of which is the core APS with DSL Bridge, Webi Monitoring, Visualization; 1 APS with LCM services; 1 APS edge with everything else remaining from the processes running under the APS) holds on to max memory allocated to it, be it 6 GB or 8 GB, once it passes a "high load" mark and reaches its allocated memory (given by -xmg8g parameter) it doesn't release it even after load is decreased, unless SIA is stopped and restarted.

So, my question is: why is that? Which service is causing it..?? Has anyone tested?

Thanks in advance for your input!

@_panda_: The APS not releasing memory contains the following services:
Adaptive Connectivity Service
DSL Bridge
Document Recovery
TraceLog service
Visualization service
WebI Monitoring service.

Platform search is not part of this APS. However, I checked in Applications and it is activily running, indexing Full content with Continious crawling. I am tempted to stop it but this wud be a change to VST test environment. I will have to postpone this as a later activity.

Main problem still remains though..

Thanks!

Post subject: Error getting after applying patch 12 on SAP BI 4.0 SP2

Error 1

When we were trying to logon from CCM, to check the manage servers; it is
showing an error pop-up " Unable to logon: could not connect to server <Server
name> :port, Please check the server name is correct and the server is running "

We found the CMS is getting stopped with the following messages

"Node Name: mcflbo01]
[User Name: SYSTEM]
Server Intelligence Agent: CMS mcflbo01.CentralManagementServer has failed and
the Server Intelligence Agent has not been able to connect to the cluster.
Please verify your CMS port and database settings are correct."

We checked with SIA properties under configuration tab and found

"Failed to Retrieve Cluster name from the database. Reason: Parser failed to
initialize"

Error 2

BW Publishers vanished from CCM which was earlier there.

---------------------------------------------------

Just to inform in this regard that Patch installation was succesful without any
errors and even prior to that everything was fine.

Thanks,
Rajib

Was this right after applying a patch? If so just roll that patch off, test the system for functionality and reinstall the patch.

I had a simliar problem and it was recommended to do this process and it worked..

Do we still have issues with APS in BI 4 ???
I'm in confusion of whether to go BOXI R3 PS5 or BI 4?
My client requirement is pretty simple. Planning to build BO from scratch, so migrations involved. Reporting db is Teradata. Planning of creating user friendly universes and Webi reports and Adhoc webi reports.
Other than these users are interested in dashboards.
Here is the server configuration what we have for BO installation,
Brand new VM with 2 CPU's 64bit and 4GB of memory.

So please advice me, should I go with BOXI R3 or BI 4???

4 GB Ram ist not enough for SAP BI 4.0 server platform. 8 GB RAM are required at minimum, start at least with 16 GB is recommended.

Post subject: Re: SAP BI 4.0 - adaptive processing servers

I just ran into this today; that is the cms not coming up and throwing the parser error. SAP fixed the problem. Here are the steps:

Attempted to log in to BI Launchpad / CMC after reboot of virtual machine. User sees error message that server is not found or down.

Launched CCM and selected SIA --> Properties --> Configuration. User sees error message Failed to retrieve cluster name from the dat
abase.

Reason: Parser failed to initialize...

Resolution:

- Observed that, we were not able to change the CMS database name from CCM.
- Tried to Recreate SIA, however it was not letting us to go through after entering dabase name and password.
- Only a small window without any error was popping up.
- Checked the trace and found error in CMS.log and SVCMgr.logs as:
\sqlruleClasses.cpp:294). (false : jsqlprs::findDFA_LLR(): Cannot find sqlrule.llr and sqlrule.dfa. Please check your Business Objec
ts executable directories. Alternatively, you can set the SQLRULEDIRECTORY system environment variable.).
- Searched for the two files : sqlrule.llr and sqlrule.dfa and found in the following directory:
C:\Program Files\SAP Business Objects\InstallData\InstallCache\platform. services.cms.cpp.dbcheck-4.0-core-64\14.0.2.364

- Copied and pasted both the files to..
.\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win64_x64 folder
- Started SIA and all the services came fine.

Also see; KBA Attached to the ticket

1553803 - After installing Patch 6 for SAP BusinessObjects 4.0 the CMS fails to start
1581285 - SBOP BI 4.0 cannot connect to the database after patch 10 installation


It worked for me. Hope it helps.

Hello everyone

We are 4.0 SP02 Patch 7.

We have been thru some pain with APS as well. We had initially cloned it and enabled only certain services on each clone, but this didnt help much and the memory consumption was enormous and we couldnt afford them with the that-time allocated 8 GB physical and 4 GB virtual memory. Finally, based on our needs (deplying Webi and Xcelsius only) we were recommended! to split the APS into 3:
APS1: DSLBridge, ACS, Documenttation recovery, Visualization and Webi Monitoring Service with 4GB allocated to this split only
APS2: LCM and Monitoring 2GB
APS3: Search and everything else 2 GB

btw: the setting of -xm2g means 2GB allocated to the service, etc.

I did try to clone as we have done before, but the clones would fail to start and we were back to 1 single APS with 2 GB memory until today, as I have created the new APS nodes from scratch. So far so good. Will update how we progress.

I know the cloning procedure had a bug previously on patch 2, and was hoping they have resolved it by patch 7, but not the case. Do not clone!

HTH


We are on 4.0 SP11, and went one step further to strip out the DSL-Bridge Service. We are experiencing same problem (if it is a problem) with servers not releasing memory - sort of defeats the purpose of the monitoring.

Does anyone know if this is fixed in any patches beyond 11?

Post subject: Re: SAP BI 4.0 - adaptive processing servers

We've had exactly the same problem. This problem was introduced with SP2 FP4. Everything worked fine before installing that. After the install I noticed that when executing one specific report the APS service went into a "starting" state but then does not go over to a "running" state. The you have to stop and start the service again. We currently have quite a few APS services, couple to only handle DSL bridge, another couple only for MDAS, another couple for WebI and then APS for all other services. All of them also have xmx and xms modified. Also have had to throw quite a lot of hardware to support this setup. Unfortunately this server is still falling over for no reason whatsoever and when looking at the parameters on the services, they all seem to loose their logging path. Only way to then fix this is to recreate the splitting of these services again. I'm not sure why this is happening and I've never received feedback from SAP as to why but one thing is for sure, I am almost 100% convinced that whatever was introduced in FP4 has caused this problem. We had BI 4 from the very first install from Ramp up and this only started with this patch.

If you mean "Patch 4 for SP02" by FP4 dude/gal you are way... behind. Definately time to upgrade to a recent patch level!

We have upgraded a long time ago, I'm merely referring that I believe that something was introduced in that specific FP that has caused all of this....in my humble opinion.

Following SP4 apparently the recommendation is now 32gb icon_rolleyes.gif

Hi, some useful information regarding APS management, memory allocation and troobleshooting (have a look to all valuable additional resources at the end of the post):
Sizing the Adaptive Processing Server in BI 4.0 by Dallas Marks.

Monitoring and alerts should help fine tuning everything.
