How to determine optimal no of concurrent manager processes

Hi,
We have a PROD env with 8 cpu and 64 G in database tier which is also the conc processing tier. The release version is 12.0.4 and OS is HP Itanium. Currently there are more than 160 conc manager processes running including the standard manager and is creating huge load during peak hrs. I want to cut down on the number of processes and implement the optimal no of processes. Looking for some suggestion on the same.
Is there any algorithm to calculate the optimal no of processes that should run depending on system hardware resource, no of users etc..
Thanks
Rit

Hi,
I do not believe such a formula exists or documented somewhere. I believe you need to tune you concurrent managers, and this depends on many factors (number of CPUs, number of users, number of concurrent requests, ..etc).
I would suggest you go through the following documents for some recommendations. You will have to adjust the Concurrent Managers parameters according to the load you have until you are satisfied with the performance. Make sure you consider reviewing the following parameters/factors:
- PMON cycle
- Sleep time
- Cache size
- Number of records in CM tables (using "Purge Concurrent Requests And/Or Manager Data" concurrent program)
- Number of standard managers
- Statistics for CM tables (using "Gather Table Statistics" concurrent program)

CPU를 많이 점유하는 CONCURRENT MANAGER PROCESSES 의 조치방법
================================================
PURPOSE
OS상에서 TOP/TOPAS같은 Monitoring tool로 볼때 FNDLIBR process중 과도하게 CPU를 많이 차지하는 것을 확인할때가 있다. 이는 CM Setup의 조정을 통해
일부 해소할수 있다. 이 Note는 이에 대해 기술하고 있다.
Explanation
우선 Process의 갯수, Sleep time을 확인해야 한다.
Process한개당 CPU 점유율을 줄이기 위해서는 Process의 갯수를 줄이고 Sleep time을 늘려줘야 한다.
1. Select the System Administrator Responsibility
2. (N)Concurrent -> Manager -> Define
3. Look up the manager that is taking all the CPU.
4. Click on the Work Shifts button. Here, you can find the number or target
processes and the sleep time.
5. Lower the number of processes, or increase the sleep time.
6. Restart the manager for the changes to take effect.
Example
만약 manager 한개당 10개의 process , Sleep time 3을 지정했다면, 10개의 process가 3초에 한번씩 처리할 job 이 있는지 확인하고 이런 빈번한 확인이 시스템에 부하를 줄수 있으므로 Sleep time을 늘리고 이를 확인하는 process의 갯수를 줄여줘야 한다.

From System Administrator responsibility, navigate to Concurrent > Manager > Administer. Query "Standard Manager", click on "Work Shifts" and verify the number of Processes.
2-The problem is basically, concurrent manager processing is very slow.Do you run "Purge Concurrent Request and/or Manager Data" concurrent program on regular basis?
How many rows you have in the FND_CONCURRENT_PROCESSES and FND_CONCURRENT_REQUESTS tables? Make sure it does in exceed 50K by running "Purge Concurrent Request and/or Manager Data" concurrent program.

CONCURRENT MANAGER SETUP AND CONFIGURATION REQUIREMENTS IN AN 11I RAC ENVIR

제품 : AOL
작성날짜 : 2004-05-13
PURPOSE
RAC-PCP 구성에 대한 Setup 사항을 기술한 문서입니다.
PCP 구현은 CM의 workload 분산, Failover등을 목적으로 합니다.
Explanation
Failure sceniro 는 다음 3가지로 구분해 볼수 있습니다.
1. The database instance that supports the CP, Applications, and Middle-Tier
processes such as Forms, or iAS can fail.
2. The Database node server that supports the CP, Applications, and Middle-
Tier processes such as Forms, or iAS can fail.
3. The Applications/Middle-Tier server that supports the CP (and Applications)
base can fail.
아래부분은 CM,AP 구성과
CM과 GSM(Global Service Management)과의 관계를 설명하고 있습니다.
The concurrent processing tier can reside on either the Applications, Middle-
Tier, or Database Tier nodes. In a single tier configuration, non PCP
environment, a node failure will impact Concurrent Processing operations do to
any of these failure conditions. In a multi-node configuration the impact of
any these types of failures will be dependent upon what type of failure is
experienced, and how concurrent processing is distributed among the nodes in
the configuration. Parallel Concurrent Processing provides seamless failover
for a Concurrent Processing environment in the event that any of these types of
failures takes place.
In an Applications environment where the database tier utilizes Listener (
server) load balancing is implemented, and in a non-load balanced environment,
there are changes that must be made to the default configuration generated by
Autoconfig so that CP initialization, processing, and PCP functionality are
initiated properly on their respective/assigned nodes. These changes are
described in the next section - Concurrent Manager Setup and Configuration
Requirements in an 11i RAC Environment.
The current Concurrent Processing architecture with Global Service Management
consists of the following processes and communication model, where each process
is responsible for performing a specific set of routines and communicating with
parent and dependent processes.
아래 내용은 PCP환경에서 ICM, FNDSM, IM, Standard Manager의 역활을 설명하고
있습니다.
Internal Concurrent Manager (FNDLIBR process) - Communicates with the Service
Manager.
The Internal Concurrent Manager (ICM) starts, sets the number of active
processes, monitors, and terminates all other concurrent processes through
requests made to the Service Manager, including restarting any failed processes.
The ICM also starts and stops, and restarts the Service Manager for each node.
The ICM will perform process migration during an instance or node failure.
The ICM will be
active on a single node. This is also true in a PCP environment, where the ICM
will be active on at least one node at all times.
Service Manager (FNDSM process) - Communicates with the Internal Concurrent
Manager, Concurrent Manager, and non-Manager Service processes.
The Service Manager (SM) spawns, and terminates manager and service processes (
these could be Forms, or Apache Listeners, Metrics or Reports Server, and any
other process controlled through Generic Service Management). When the ICM
terminates the SM that
resides on the same node with the ICM will also terminate. The SM is ？hained?
to the ICM. The SM will only reinitialize after termination when there is a
function it needs to perform (start, or stop a process), so there may be
periods of time when the SM is not active, and this would be normal. All
processes initialized by the SM
inherit the same environment as the SM. The SM environment is set by APPSORA.
env file, and the gsmstart.sh script. The TWO_TASK used by the SM to connect
to a RAC instance must match the instance_name from GV$INSTANCE. The apps_<sid>
listener must be active on each CP node to support the SM connection to the
local instance. There
should be a Service Manager active on each node where a Concurrent or non-
Manager service process will reside.
Internal Monitor (FNDIMON process) - Communicates with the Internal Concurrent
Manager.
The Internal Monitor (IM) monitors the Internal Concurrent Manager, and
restarts any failed ICM on the local node. During a node failure in a PCP
environment the IM will restart the ICM on a surviving node (multiple ICM's may
be started on multiple nodes, but only the first ICM started will eventually
remain active, all others will gracefully terminate). There should be an
Internal Monitor defined on each node
where the ICM may migrate.
Standard Manager (FNDLIBR process) - Communicates with the Service Manager and
any client application process.
The Standard Manager is a worker process, that initiates, and executes client
requests on behalf of Applications batch, and OLTP clients.
Transaction Manager - Communicates with the Service Manager, and any user
process initiated on behalf of a Forms, or Standard Manager request. See Note:
240818.1 regarding Transaction Manager communication and setup requirements for
RAC.
Concurrent Manager Setup and Configuration Requirements in an 11i RAC
Environment
PCP를 사용하기위한 기본적인 Setup 절차를 설명하고 있습니다.
In order to set up Setup Parallel Concurrent Processing Using AutoConfig with
GSM,
follow the instructions in the 11.5.8 Oracle Applications System Administrators
Guide
under Implementing Parallel Concurrent Processing using the following steps:
1. Applications 11.5.8 and higher is configured to use GSM. Verify the
configuration on each node (see WebIV Note:165041.1).
2. On each cluster node edit the Applications Context file (<SID>.xml), that
resides in APPL_TOP/admin, to set the variable <APPLDCP oa_var="s_appldcp">
ON </APPLDCP>. It is normally set to OFF. This change should be performed
using the Context Editor.
3. Prior to regenerating the configuration, copy the existing tnsnames.ora,
listener.ora and sqlnet.ora files, where they exist, under the 8.0.6 and iAS
ORACLE_HOME locations on the each node to preserve the files (i.e./<some_
directory>/<SID>ora/$ORACLE_HOME/network/admin/<SID>/tnsnames.ora). If any of
the Applications startup scripts that reside in COMMON_TOP/admin/scripts/<SID>
have been modified also copy these to preserve the files.
4. Regenerate the configuration by running adautocfg.sh on each cluster node as
outlined in Note:165195.1.
5. After regenerating the configuration merge any changes back into the
tnsnames.ora, listener.ora and sqlnet.ora files in the network directories,
and the startup scripts in the COMMON_TOP/admin/scripts/<SID> directory.
Each nodes tnsnames.ora file must contain the aliases that exist on all
other nodes in the cluster. When merging tnsnames.ora files ensure that each
node contains all other nodes tnsnames.ora entries. This includes tns
entries for any Applications tier nodes where a concurrent request could be
initiated, or request output to be viewed.
6. In the tnsnames.ora file of each Concurrent Processing node ensure that
there is an alias that matches the instance name from GV$INSTANCE of each
Oracle instance on each RAC node in the cluster. This is required in order
for the SM to establish connectivity to the local node during startup. The
entry for the local node will be the entry that is used for the TWO_TASK in
APPSORA.env (also in the APPS<SID>_<HOSTNAME>.env file referenced in the
Applications Listener [APPS_<SID>] listener.ora file entry "envs='MYAPPSORA=<
some directory>/APPS<SID>_<HOSTNAME>.env)
on each node in the cluster (this is modified in step 12).
7. Verify that the FNDSM_<SID> entry has been added to the listener.ora file
under the 8.0.6 ORACLE_HOME/network/admin/<SID> directory. See WebiV Note:
165041.1 for instructions regarding configuring this entry. NOTE: With the
implementation of GSM the 8.0.6 Applications, and 9.2.0 Database listeners
must be active on all PCP nodes in the cluster during normal operations.
8. AutoConfig will update the database profiles and reset them for the node
from which it was last run. If necessary reset the database profiles back to
their original settings.
9. Ensure that the Applications Listener is active on each node in the cluster
where Concurrent, or Service processes will execute. On each node start the
database and Forms Server processes as required by the configuration that
has been implemented.
10. Navigate to Install > Nodes and ensure that each node is registered. Use
the node name as it appears when executing a nodename?from the Unix prompt on
the server. GSM will add the appropriate services for each node at startup.
11. Navigate to Concurrent > Manager > Define, and set up the primary and
secondary node names for all the concurrent managers according to the
desired configuration for each node workload. The Internal Concurrent
Manager should be defined on the primary PCP node only. When defining the
Internal Monitor for the secondary (target) node(s), make the primary node (
local node) assignment, and assign a secondary node designation to the
Internal Monitor, also assign a standard work shift with one process.
12. Prior to starting the Manager processes it is necessary to edit the APPSORA.
env file on each node in order to specify a TWO_TASK entry that contains
the INSTANCE_NAME parameter for the local nodes Oracle instance, in order
to bind each Manager to the local instance. This should be done regardless
of whether Listener load balancing is configured, as it will ensure the
configuration conforms to the required standards of having the TWO_TASK set
to the instance name of each node as specified in GV$INSTANCE. Start the
Concurrent Processes on their primary node(s). This is the environment
that the Service Manager passes on to each process that it initializes on
behalf of the Internal Concurrent Manager. Also make the same update to
the file referenced by the Applications Listener APPS_<SID> in the
listener.ora entry "envs='MYAPPSORA= <some directory>/APPS<SID>_<HOSTNAME>.
env" on each node.
13. Navigate to Concurrent > Manager > Administer and verify that the Service
Manager and Internal Monitor are activated on the secondary node, and any
other addititional nodes in the cluster. The Internal Monitor should not be
active on the primary cluster node.
14. Stop and restart the Concurrent Manager processes on their primary node(s),
and verify that the managers are starting on their appropriate nodes. On
the target (secondary) node in addition to any defined managers you will
see an FNDSM process (the Service Manager), along with the FNDIMON process (
Internal Monitor).

What is your database version? OS?
We are using VCP suite for Planning Purpose. We are using VCP environment (12.1.3) in Decentralized structure connecting to 3 differect source environment ( consisting 11i and R12). As per the Oracle Note {RAC Configuration Setup For Running MRP Planning, APS Planning, and Data Collection Processes [ID 279156]} we have implemented RAC in our test environment to get better performance.
But after doing all the setups and concurrent programs assignment to different nodes, we are seeing huge performance issue. The Complete Collection which takes generally on an avg 180 mins in Production, is taking more than 6 hours to complete in RAC.
So I would like to get suggestion from this forum, if anyone has implemented RAC in pure VCP (decentralized) environment ? Will there be any improvement if we make our VCP Instance in RAC ?Do you PCP enabled? Can you reproduce the issue when you stop the CM?

Oracle RAC Concept - load balancing

Hello All,
I have a question about Oracle RAC and how it balance loading.
What I know about Oracle RAC that it balancing load between its node, so if a new session is connected to the Database it will execute on the node which have less load.
If I am having an application that connects to the database with few number of sessions and some sessions have huge (huge load) processes to execute while the other sessions are executing small process (in terms of load).
So below is an example scenario that i am asking for an answer of it:
if am having a two node RAC database.
My application that is connected to this RAC database wants to execute three processes P1, P2 and P3 each will have a session correspondingly S1, S2 and S3
Let is say that P1 will take 60% of the database resources (memory ....) and P2 will take 1% and P3 1%.
So my question is it a sessions load balancing or Processes load balancing ? So in case and randomly (Managed by ORACLE RAC) S1 is connected to node 1 and it is using node 1 resources so the load on node 1 will be 60%, so when S2 and S3 needs to connect it will go to node 2 since node 1 is loaded. in that case i will have Node 1 using 60% of it is resources (becuase of S1 that is executing P1) while node 2 only uses 2 % (because of S2 and S3 that is executing P2 and P3).
Is that how Oracle RAC works ? or it balance the load of S1 (60%) between node 1 and node 2 ?
I am asking this question since my application is not users application, so it will connect to the database with few number of sessions, and 1 session of them may execute a huge process while the other are executing small processes.
So in that case, how RAC is doing the balance loading?
Regards,

i hope , this links may help you.

Question about Cluster/DSync/Load Balance

According to the admin doc of iplanet, primary server is
the "manager" for data sync, is there any impact on
load balance when the iAS run as primary or backup?
will the primary kxs get the request first and do dispatching?
Thanks.
Heng

First of all lets discuss load balancing....
The type of load balancing you are using will determine which process manages the load balancing. If you are using Response time (per server or per component response time) or round robin (regular or weighted) the web connector does the load balancing. If you are using User Defined (iAS based) load balancing then the kxs process becomes involved with load balancing of requests since the "Load Balancing System" is part of the kxs process.
Now for Dsync and how it impacts load balancing.
When a server is a sync primary or a sync backup role it is doing more work. For the sync primary the extra work is making sure the backup has the latest Dsync Data and processing requests from the other servers in the cluster about the Distributed data. All state/session information is updated/created/deleted on the sync primary, when this happens the sync primary immediately updates the sync backup(s) with this new information. As you can guess managing the Dsync information and making the updates to the sync backups causes extra processing on the sync primary, so this will impact the overall performance of the machine (whether it be in server load or response time of processing). All lookup of state/session information is done on the sync primary only so the more lookups/updates you have to more impact on the server.
The sync backup(s) also have the extra work of managing their copy of the Dsync Data which will impact server performance but to a lessor degree of the sync primary.
Ultimately the extra overhead involved does have an impact on loadbalancing due to the extra load on the sync primary and sync backups.
Hope that helps,
Chris Buzzetta

Cisco ACE - Firewall load balancing

I am using two sets of ACE load balancers for load balancing traffic across two firewalls (firewall load balancing).
The solution works fine. I have a virtual address of 0.0.0.0 in either direction to match traffci going from the internal users to the internet and vice versa.
The problem is that when I try to manage the load-balanced firewalls (either using SSH (or) HTTPS) from outside, then that connection also gets load balanced and when I try to connect to FW1 then sometimes this connection ends up on FW2 and vice versa and the connection gets dropped. I have a workaround in place where i am using a virtual address per firewall to connect to the real IP address of the firewall.
Is there any other way of managing firewalls (which are defined as real-servers) in a FWLB setup.
Attached is the configuration of the external ACE which has the two firewalls defined as the real-servers.

H-REAP and Client Load-Balancing

I'm told by Cisco that H-REAP does not support client load-balancing.
We have a situation where we want to deploy LWAPPs using H-REAP into a conference room where training would take place.
Any suggestions on how to overcome the inevitable slowness these people are going to experience from being unevenly associated with the APs?
We can't re-write the application so we are looking for a wireless solution.
Anyone hear about how other organizations have dealt with this type of situation?
I'll be glad to supply more details if I am not being clear in my description of the problem.
Thanks in advance. All responses will be rated.

This is the functionality which is missing in H-REAP: Client and Network Load Balancing
"Radio Resource Management (RRM) load-balances new clients across grouped lightweight access points reporting to each controller. This function is particularly important when many clients converge in one spot (such as a conference room or auditorium) because RRM can automatically force some subscribers to associate with nearby access points, allowing higher throughput for all clients. The controller provides a centralized view of client loads on all access points. This information can be used to influence where new clients attach to the network or to direct existing clients to new access points to improve wireless LAN performance. The result is an even distribution of capacity across an entire wireless network.
Note: Client load balancing works only for a single controller. It is not operate in a multi-controller environment."
I suppose if we limit the number of users that can associate with a particular AP then we will achieve some client load-balancing. Though a hard limit on the number of end-users will also lead to situations where some end users will not be allowed any access.

Concurrent Manager Issue in Oracle Apps 11i on MS Windows 2003

Hi,
We have Oracle Apps 11i (11.5.10) on Windows 2003 running Oracle Financilas and Supply Chain.
From this morning onwards, concurrent requests are not getting completed. All requests are showing Running Normally. I checked the server (Single Node 4 GB Memory) and CPU usage is more than 90%. Task Manager is showing 50% CPU usage for SYSTEM (Image Name). Once the CPU usage for SYSTEM(image name) goes beyond 40% then the server is becoming slow and the problem starts.
When I stop the Concurrent Manager it does not stop and I have to End Process the FNDLIBR process manually.
I have recreated the concurrent manager using CCMSETUP and also ran cmclean.sql. Nothing is helping.
System is Live since 2006 and the issue started only today.
Please suggest any solutions as this is happening in our Production system.
Thanks.
Thiru

Thiru,
Which concurrent manager consumes the CPU usage? Are you able to identify it?
Any errors in the CM log file? Did you try to start the CM with diag=y and see if any errors are reported in the log files?
What happen to the CPU usage when you stop the CM?
I assume that you are running Purge Concurrent Manager/Requests on regular basis, so this should not be an issue here.
Please review the following notes, and see if it helps.

System is Live since 2006 and the issue started only today.I assume no changes have been done recently, correct?

Re: concurrent manager quest

Hello,
Sometimes even we kill the concurrent manager process at os level but that session still exits in the database.So now how can we verify the control code of concurrent managers in the database.Kindly tell me.

Sometimes even we kill the concurrent manager process at os level but that session still exits in the database.So now how can we verify the control code of concurrent managers in the database.Kindly tell me.If you kill the CM process from the OS, you do not need to kill any concurrent manager sessions from the database.
If you terminate a concurrent request, then you can kill the database sessions (if any exist) from the database using (Concurrent Processing - How to Find Database Session & Process Associated with a Concurrent Program Which is Currently Running. [ID 735119.1]).
