Maximum number of nodes in Multimaster Replication
Has anyone setup a multimaster replication environment on 8.1.7 with more than 11 nodes?
What could be the maximum number of nodes for reliable operation?
Hi,
With Oracle 8.1 you can have upto 9; but I think you can have under one of the replicated DB another replicated DB. tree like tructure.
Best,
EA

Maximum number of nodes reached
Hello all,
I am currently trying to explain a problem with one of our WF run and I just found out, under the "Step History" tab of a Work Item, the error message "Maximum number of nodes reached" was logged. That certainly explains the problem but I have some questions regarding such a message:
1) If WF-A calls a subworkflow WF-B, does this limit of 10,000 nodes apllies for the whole WF run (i.e. WF-A nodes + WF-B nodes) or is it 10,000 nodes for WF-A and 10,000 nodes for WF-B?
2) In our situation, the error was logged within the WF-B (subworkflow) work item which I beleive caused WF-A to fall into an error status. Some people have tried to re-execute the WF-B workitem without any success... Always the same error was reported. Is there anyway to re-start a WF that is in Error if it has reached this limit of nodes?
Thanks.
JoséHello Rick,
You are right, this worfwlow run was started back in May 2010 and yes, it is for the creation of a new point of sale. I understand when you say that obviously, the business managed to survive and we should cancel and restart and this is exactly what we are investigating at the moment but this customer wanted us to try to restart it considering, I suppose, the amount of work already completed in this workflow (which contains many subworkflows that are also in progress and stopped because of this problem).
To your question "How come this error didn't affect other wokflow instances?", I would say that the customer have been lucky so far because there was a design issue in this workflow definition but the "context" required to create this error happened only once since its implementation. However, they are still at risk and this WF definition requires a modification for sure to prevent this from happening again in the futur.
Concerning this 10,000 value, I've asked myself the same question since the change in the customizing made no differences, it has to be kept somewhere inside the workflow instance but where?. I have chekced all the elements of the WF container but, not there!
I will investigate with SWI2_DIAG, thanks for the hint and I will let you know through this thread.
Merci ! (Thanks)

Maximum Number of Nodes 10000 reached
Hi Im using a loop condition for deadline rendering with system time then the worlkflow showing error with the message
"Maximum Number of Nodes 10000 reached" where im going wrong
im checking my dealine requirement for every 3 minutes by using loop condition original requirement is to check for every 3 days
im confused over here where im going wrong
ThanksHi Prasad,
As suggested by our friends, there is no termination condition in the loop , and it has become an infinite loop.
To elaborate this error description, find extarcts from help :
Maximum number of nodes that can be processed at runtime before the workflow runtime system assumes an endless loop and cancels the current workflow.
The presetting for this value is 10000.

Workflow erro: maximum number of nodes for a session reached
Hi
a number of workflows went into error with message maximum number of nodes for the session reached 11000 . what can be the reason . is there some settings thats need to be made in production . because it is working in dr3 and qr3Hi,
Check the condition on the loop for you workflow. It seems its getting into infinite loop.
Also check for the possibility FM which might be triggering your workflow is getting executed in an infinite loop. So it might trigger multiple instances of the same workflow.

Maximum number of nodes in a Weblogic cluster on RedHat Linux?
Is there a limitation of the number of nodes in a weblogic cluster
running under RedHat Linux?
Can I start with 5 nodes and in a year scale up to 500 or 5000 nodes?
Thanks!
Ralf.
Ralf,

A realistic limit, of course.
> Can I start with 5 nodes and in a year scale up to 500 or 5000 nodes?
If your app is completely stateless, then it can scale to 40 maybe 80
servers.
The problem is that stateless apps typically manage state that sits behind
them, and there's basically no database in the world that can handle the
load that 40 servers can put on it. Depending on the app, you can easily
saturate 4 database CPUs per 1 app server CPU, but usually the factor is
closer to 1:1, and with agressive caching in the app tier even less.
Things like stateful session bean replication and HTTP session replication
in a cluster ... well, YMMV ... but I would hypothesize that it won't scale
up anywhere close to 40 servers under load.

Set maximum number of BPM nodes
Hy all,
can someone tell me how can i set the maximum number of bpm node in XI.(Transaktion for example)
Thank's a lot.
MatHi Jürgen,
You can try changing this with TCODE: SWPA
"Maximum node number" parameter
By default the value is 10.000 (at least on my DEV XI)
maybe this will help you

Maximum number of RAC services in a Node
DB, Grid Version: 11.2.0.3/RHEL 5.4
My question is on the preferred node for a RAC service.
What is the maximum number of RAC services that can created in a node ?Hi,
You can add maximum 145 service different default services.
It is not documented information.

Xs:group refs and "ORA-30936: Maximum number (1) of XML nodes exceeded'
We registered a subset of the IBM DITA schemas in Oracle XDB. These schemas contain a lot of xs:group definitions where references to these groups contain "minOccurs" and "maxOccurs" atttributes, for instance:
<xs:group name="category">
<xs:sequence>
<xs:element ref="category"/>
</xs:sequence>
</xs:group>
<xs:complexType name="metadata.class">
<xs:sequence>
<xs:group ref="audience" minOccurs="0" maxOccurs="unbounded"/>
<xs:group ref="category" minOccurs="0" maxOccurs="unbounded"/>
<xs:group ref="keywords" minOccurs="0" maxOccurs="unbounded"/>
<xs:group ref="prodinfo" minOccurs="0" maxOccurs="unbounded"/>
<xs:group ref="othermeta" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="mapkeyref" type="xs:string"/>
<xs:attributeGroup ref="global-atts"/>
<xs:attribute ref="class" default="- topic/metadata "/>
</xs:complexType>
When we create an instance document that contains more than one "category" element under the element "metadata" element, like:
<metadata>
<audience type="purchaser" othertype="" job="using" otherjob="" experiencelevel="general"/>
<category/>
<category/>
</metadata>
we get the error: ORA-30936: Maximum number (1) of 'category' XML node elements exceeded
This error is not consistent with the schema and XML parsers like Xerces and the Oracle "XDK parser" think the instance is fine.
When we skip the reference to the group and reference the element definition "category" directly the problem is gone:
<xs:complexType name="metadata.class">
<xs:sequence>
<xs:group ref="audience" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="category" minOccurs="0" maxOccurs="unbounded"/>
<xs:group ref="keywords" minOccurs="0" maxOccurs="unbounded"/>
<xs:group ref="prodinfo" minOccurs="0" maxOccurs="unbounded"/>
<xs:group ref="othermeta" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="mapkeyref" type="xs:string"/>
<xs:attributeGroup ref="global-atts"/>
<xs:attribute ref="class" default="- topic/metadata "/>
</xs:complexType>
In this case the problems for the other group references like "audience" remain.
It looks like Oracle XDB doesn't honor the cardinality attributes "minOccurs" and "maxOccurs" on xs:group elements that are references. Does anyone experienced similar problems?
Thanks,
MaartenThis sounds like bug 5204107. You'll need to open a tar with Oracle Support if you need a fix for this..
It happens when a group is used once without a maxOccurs and then later with a maxOccurs.
The workaround is 'in-line' the group before registering the XML Schema. This can be done as follows (assuming the group definition and reference are in the same XML Schema)..
procedure expandGroup(xmlschema in out xmltype, groupName varchar2,xsdDirectory varchar2)
is
xsdSchemaPath varchar2(512);
groupModel xmltype;
sequenceModel xmlType := xmlType('<xsd:sequence ' || xdb_namespaces.XMLSCHEMA_PREFIX_XSD || '><xsd:sequence/></xsd:sequence>');
maxOccursValue binary_integer;
begin
-- FInd the Group Definition
if xmlSchema.existsNode('/xsd:schema//xsd:group[@ref="' || groupName || '"]',NAMESPACES) = 1 then
if xmlSchema.existsNode('/xsd:schema/xsd:group[@name="' || groupName || '"]',NAMESPACES) = 1 then

) = 1;
dbms_output.put_line('Resolved ' || groupModel.extract('/xsd:group/@name',NAMESPACES).getStringVal() || ' in Schema ' || xsdSchemaPath);
end if;
if groupModel.existsNode('/xsd:group/xsd:annotation',NAMESPACES) = 1 then
select deleteXML

'/xsd:group/xsd:annotation',
NAMESPACES

end if;

Maximum number of server nodes for a dispatcher
Hi,
Is there a maximum (recommended) number of server nodes that can be created per dispatcher, for the 6.40 J2EE Engine? We are considering using a 16GB RAM server with 1 dispatcher and 8 server nodes to run our EP6 SP18 portal. Are there any implications we should be aware of with this setup? Is there any additional configuration for the dispatcher necessary for a high number of server nodes?
Any advice greatly appreciated, points will be awarded.
Many thanks

Increasing maximum number of Logical Processors in a Processor Group greater than the default (64)
Can the maximum number of Logical Processors allowed in a Processor Group be increased by Bcdedit command or registry key to a number greater than the default (64) to allow non-group-aware applications to seamlessly scale via multithreading across more cores
MSDN documents methods to reduce the max number of LP's in a Processor Group to 1 or any power of 2 less than 64 in order to increase the number of Processor Groups. But there is no discussion of how to increase the maximum number of Logical Processors
allowed in a Processor Group to a number greater than the default (64), e.g. to 128 or 256.
Since a non-group-aware application/process can only run on 1 Processor Group, increasing this limit is needed to allow non-group-aware multithreaded applications to scale seamlessly for parallel computation across more than 64 cores simultaneously on systems
with more than 64 cores (for example, a quad-socket Intel Xeon system with 24 cores per socket, including true and hyper cores). If that limit can be set via registry key or command line, or if there is another way to force all the cores on
all 4 sockets (4 NUMA nodes in this case) to join in 1 Processor Group, then non-group-aware applications will not need to be rewritten using group-aware thread-affinity APIs.Hi John,
Are you trying to specify a static NUMA-node-to-group assignment, rather than letting Windows dynamically assign NUMA nodes to groups at boot time? If yes, You can refer the
following related KB:
How to manually configure K-Group assignment on multiprocessor machines
http://support.microsoft.com/kb/2506384
Systems with fewer than 64 logical processors always have a single group, Group 0. On systems with 64 or fewer processors, existing applications will operate correctly without
modification. Applications that do not call any functions that use processor affinity masks or processor numbers will operate correctly on all systems, regardless of the number of processors. To operate correctly on systems with more than 64 logical processors,
the following kinds of applications might require modification:
•Applications that manage, maintain, or display per-processor information for the entire system must be modified to support more than 64 logical processors. An example of
such an application is Windows Task Manager, which displays the workload of each processor in the system.
•Applications for which performance is critical and that can scale efficiently beyond 64 logical processors must be modified to run on such systems. For example, database
applications might benefit from modifications.
•If an application uses a DLL that has per-processor data structures, and the DLL has not been modified to support more than 64 logical processors, all threads in the application
that call functions exported by the DLL must be assigned to the same group.
By design, a non-NUMA computer is considered to have one NUMA node. Because NUMA nodes cannot span groups, the system creates a node for each group after you restart the computer.

Maximum number of service in a database?
Somebody can tell me if there is a maximum number of service I can use in a database? Those services are create with dbms_service or "srvctl add service" or dbca. Those services are set in the database parameter SERVICE_NAME automatically by the Clusterware or manually if it is not a cluster database.
Thank,
GGI would tend to be suspicious just because 50 services is quite a lot. If you really have 50 distinct applications and you want to manage 50 different services, 50 different TNS aliases, etc. you certainly can. But most organizations aren't going to see a lot of benefit from having that many services and may end up spending a lot of time micro-managing things the system unnecessarily.
You would generally have separate services if you wanted to have different services on different nodes of the cluster (i.e. create a reporting service on a subset of the nodes of the cluster for reporting work so that doesn't get comingled with the OLTP workload on the other nodes). It would be rather hard to manage 50 services on the same cluster effectively-- you'd either have all 50 services spread across all the nodes, in which case there would be little benefit to having all those services, or you'd have something like 5 services on each of 10 nodes which would tend to result in poor load balancing (assuming the load profile of each application is rather variable) or lead to constant administrative "futzing" to improve load balancing.

Maximum number of fabric logins
Hi there
I need to provide documented references for a large SAN, and have a few queries.
I have the show tech-supports for an edge-core-edge SAN consisting of 2 redundant fabrics.
There are 4 host edges, 1 core, 4 storage edges per fabric. All are MDS 9500 series directors, running SAN-OS 3.2.2a.
In the Large SAN Design Best Practices whitepaper
(http://www.cisco.com/en/US/prod/collateral/ps4159/ps6409/ps5990/white_paper_C11-515630.pdf)
there is a reference to the maximum number of fabric logins.
"The Cisco MDS Family supports up to 10,000 fabric logins in a physical fabric, regardless of the number of VSANs in the network."
1) Is this specifically refering to the number of f_ports?
2) If not, what is the 10,000 referring to?
In the Cisco MDS NX-OS Release 5.0 Configuration Limits
(http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/sw/5_0/configuration/guides/limits/limits_50.html)
there is a mention of 10000 FCNS entries per fabric.
This is the only reference I can find that correlates the two limits.
The Configuration Limits for Cisco MDS SAN-OS Release 3.x
(http://www.cisco.com/en/US/products/ps5989/prod_troubleshooting_guide_chapter09186a0080679fd4.html)
makes no mention of FCNS or fabric login limits.
3) Is the reference to 10000 FCNS entries (in the NX-OS 5 limits) also the number of fabric logins?
In the show tech-support, there is a command
`show tech-support fcns`
`show fcns database vsan 1-4093`
VSAN 431:

It shows that most of the entries have the port-type: N.
5) Does this mean they are N_ports, not F_ports?
I would really appreaciate answers to these questions.John,
Cisco NXOS Configuration Limits (reference/background link)
1) Is this specifically refering to the number of f_ports?
Answer: Yes, the 10k logins in the Design Guide Whitepaper refer to the number of Fabric logins, not the number of physical ports. This is because you could have a single F_Port that has multiple logins as part of it. For example, an Nexus 5000 in NPV mode could connect to a MDS 9513 via one F_port (NP_Port on the Nexus 5k), but have many Fabric Logins (technically, one FLOGI and multiple FDISC).
2) If not, what is the 10,000 referring to?
Answer: Number of devices logged into the Fabric not the number of ports in the fabric.
3) Is the reference to 10000 FCNS entries (in the NX-OS 5 limits) also the number of fabric logins?
Answer: Yes, since every device out there that FLOGIs into the fabric registers with the nameserver.
4) In the below output does this mean that there are 1066 fabric logins?
In the show tech-support, there is a command
`show tech-support fcns`
`show fcns database vsan 1-4093`

It shows that most of the entries have the port-type: N.
Answer: An N_Port is an end device like a storage port or an HBA, which connects to an F_Port (Fabric Port) which is the corresponding port on the switch. This is why you see it as an port-type of N, rather than NL (Node Loop) F, E, or FL (Fabric Loop), as only N or NL can represent the end device itself and not the port on the switch.
Hope this helps,

ASM maximum number of processes (300) exceeded
Hi Everyone,
My Oracle database is 11g r2(11.2.0.2.0) and linux version is redhat 5.5.
In ASM one of our diskgroup getting full. so we added 5 disks to diskgroup with size of 545 GB lun(disk) each..succesfully added diskgroups but while rebalancing is going on ASM instance got stuck and node got hanged up and from application side process got stuck up and thrown with the below error from alert log, for temporariy solution we rebooted the first node.

can you please let us know the solution for the above error
Thanks in advance
Thanks & Regards
PrasanthHi Jos
--> How to calculate ASM Parmaeter process? with which view i can get the information?
-->I cheked with below command by connecting ASM instance show below like 300 process .But while doing any operation on ASM crossing 300+ connection of process.
SQL>show parameter process
NAME TYPE VALUE
processes integer 300
--> I confirmed by checking by ps -aef|grep beq command in linux it shown 380 beq connection.
--> Power limit i given 5 while adding disks to diskgroup..!
--> long back ago we changed ASM Parameter process value to 300 in place of 100.
--> A question like while rebalancing is going node got hanged got alert error like ASM MAXIMUM PROCESS GOT EXCEED so no operation were allowed to the node, so we rebooted the node after rebooted node came in to normal state and able to do all operation normally..but my question is that rebalance is completed succesfully or not?
--> For this issue we need to apply any Patch to overcome this issue in future while doing any operation on ASM
Thanks a lot for your quick reply.
Thanks & Regards
Prasanth
