TimerManager in non-clusterer environment

Hi all,
Is it possible to lookup TimerManager object in a POJO? Since it's not EJB I don't know the JNDI name of TimerManager, and I couldn't find it in JNDI tree.
@Resource injection will not work in this case.
Any help would be greatly appreciated.

For role-based vlan mapping, the vlan is switched to the final vlan and then agent requests an ip refresh since if you had the access vlan IP address, and you're now in a new vlan, network access wont be there.
I don't think we have any white papers discussing setting up NAC with static IPs, but I'll look.
HTH,
Faisal

OSM v7.2 - More that 1 instance in a non clustered environment

I am just wondering...
1) Can i install OSM separately on 2 servers while using the same database instance in a non-clustered manner?
This is for circumstances where I need a dedicated server resource for bulk provisioning for example.
2) If I am not using AIA in my implementation, how does COM calls a SOM cartridge and how does SOM reply COM on the completed status?
Is it via some default provided webservice, or do i need to find a way to implement it myself.
Thanks :)

Hi,
1. Though technically it is feasible to use two OSM instances with same database, it is not suggested as it may lead to locking issues and not sure how you are planning to acheive bulk provisioning by this way
2. The calling of SOM cartridge by COM and status updates of SOM to COM has to be implemented by yourself if you are not using AIA. You can make use of default webservices proivded by OSM

Remote JMS Queue in Non-Clustered Environment

          We have two hosts, both running WLS 8.1, that are not clustered. We would like
          to create a queue on the first and be able to read it from the second. Is this
          possible? How does one go about setting this up?

          Hi Paul,
          This a common use case. Even user transactions
          can include operations from both servers.
          The remote server just looks a regular
          client as far as the JMS server is concerned.
          I recommend using MDBs - which can be be configured with a URL
          and connection factory, messaging bridges, and/or foreign destination
          wrappers. In addition, you can use the JMS resource reference
          pooling feature to pool the "foreign" JMS server's resources.
          For information you can start here:
          http://edocs.bea.com/wls/docs81/jms/intro.html#jms_features
          and here:
          http://dev2dev.bea.com/technologies/jms/index.jsp
          Important: As documented, for various reasons, some not
          having to do with JMS, you will need to ensure the following are
          true to enable "non-clustered" communication:
          - all domains should be named uniquely
          - all wl servers must be named uniquely
          - all jms servers must be named uniquely
          - all jms stores must be named uniquely

Load balancing, failover and fallback in Non-Clustered WebLogic environment

hi,
Has anyone implemented WebLogic 10.3.3 (or 10.3.4) in a Non-Clustered environment, but also got load balancing, failover and fallback work?
We were successful in getting failover working using t3://server1:7001,server2:7002 provider URL, but not load balancing or fallback.
The fallback is working when it was connecting to server2 and if we kill server2, then it switches to server1, but not when server2 is still running while server1 comes back.
All we need to find a way to enforce fallback to primary site, even if secondary which the client connected is still up and running and primary site comes back.
Any help appreciated.
Thanks.
Best regards,
Bala

OCFS2 in a non-RAC environment

Here's a question I've been batting around with a sysadmin. I thought I'd run it past this group.
We're spec'ing out the hardware for a very large Oracle database (3+ TB) running on Linux. This will be a single, non-RAC instance. This particular SA has very bad feelings about the ext3 filesystem (I am not exactly sure what his objections are). He has heard about ocfs2 and wonders if it would be superior to ext3.
What do you think? Would ocfs2 be appropriate in a non-clustered environment? Can you suggest any arguments for or against this approach?
Thanks, I appreciate any thoughts anyone might have.

Note that paper was written in 2004, and their tests used Pentium III processors. The OS was RHAS 2.1 and their kernel was 2.4.9
I'm not saying that invalidates the paper's conclusions, but I'm certainly saying you'd have to be very careful indeed in assuming that conclusions drawn from that combination of hardware and software had anything much to say about today's quad cores, multi-gigabyte RAM, kernel 2.6.x setups.
I'm concerned when I see their graphs on page 8: no axis scales in either x or y directions. If they're going to come to the conclusion that ext2/3 performance tails off, it would be nice to know whether it does so when the number of users hits 10, 50, 100, 500 or whatever, wouldn't it? But you can't tell anything from their graphs on that score.
And I don't see any mention of them adjusting the buffer cache when using raw, which (having just abolished the file system cache) is something you should sensibly do when making such comparisons.
And, of course, they were testing OCFS not OCFS2, so again... the applicability of anything concluded in that paper to today's situation is highly questionable, at least in my mind. But I do note that OCFS with "high numbers" of users ended up clobbering the CPU to death, whereas ext2/3 didn't...
And they seem to claim that transactions per second levelled out with ext2/3 because they hit a lot of free buffer waits -and there are ways of dealing with them that don't involve getting rid of the file system! The fact that they didn't report a lot of write complete waits as well as free buffer waits might indicate that they just need more DBWRs, and not a switch of file system, for example.
Anyway... short answer is, I wouldn't read too much into that report, which looks to me to be poorly devised and written and very much 'of its time and place' with little general applicability outside of that.

Instnce name in non-RAC environment

Hi!
In non-RAC environment V$INSTANCE.INSTANCE_NAME does not actually displays the name of the instance,that was set in INSTANCE_NAME parameter.
It always displays DB_NAME instead.
Is it any way to get instance_name that has service user connected to in this environment?

This would imply that setting INSTANCE_NAME in non-RAC is ignored. The usage of the word "usually" is weak.

Regarding issue sender file adapter in clustered environment(PI 7.0)

Hi Experts,
we are using sender file adapter in clustered environment(there are 6 J2EE cluster nodes in XI system) for an interface.the file sender communication channel for this interface is scheduled to run twice every day. recently the channel stopped polling (picking the files from the source directory) and i dont see any error.
when i open Communication Channel monitoring in RWB and select the file sender communication channel and run it manually, none of the cluster nodes are polling for the file.
i have tried editing the communication channel in Integration Directory and activating it. but it does not pick the file.
Can you let me know how the issue can be resolved.
Thanks

Edited by: Kausik M on Dec 18, 2008 4:13 AM

Kausik,
A computer cluster is a group of linked computers, working together closely so that in many respects they form a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and/or availability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.
clearly your cluster nodes are out of sync...!!!!
It is possible that your ftp server went down for a while . And in the profile of FTP machine the entry of XI server is not made permanent .
1. Try to ping the FTP site from XI server.
BTW are u getting any error msg at RWB ?

IS IT SUPPORTED TO CENTRALLY MOUNT THE ORACLE_HOME IN A NON-RAC ENVIRONMENT

SR 7250090.993 : (http://qmon.oraclecorp.com/qmon3/quickpicks.pl?t=t&q=7250090.993)
Technical Summary:
Customer is planing to install Oracle 10.2.0.4 and 11.1.0.x software on a Red Hat5 with NetApp storage.
Customer came across the following :
For single instance installations (as opposed to RAC installations), you must create a separate Oracle home directory for each installation. Run the software in this Oracle home directory only from the system that you used to install it. For Oracle Real Application Clusters (RAC) installations, you can use a single Oracle home directory mounted from each node in the cluster. You must mount this Oracle home directory on each node so that it has the same directory path on all nodes.
mentioned in the 10gR2 documentation link :
http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/app_nas.htm#BCFIDEJA
Requirements/Expectations:
As the above statements, that customer came across is not present in 9i documentation, customer wants to understand if it is actually supported to centrally mount the 10g/11g ORACLE_HOME to many servers that are not RAC enabled.
Also, I would like to understand if the statements in documentation indicate that it is not generally recommended centrally mount the 10g/11g ORACLE_HOME or does it mean that it is not supported to centrally mount the ORACLE_HOME in a non RAC environment?
Please advice.

The binaries (executables) in an Oracle home are "linked" (link edited?) to the OS libraries on each server where the software is installed.
Unless the OS is IDENTICAL on each of the IDENTICAL(HW) servers -- that would share the Oracle home--, you could be in trouble.
The only supported configuration (I know of) where the Oracle binaries are shared between servers is 9i RAC. On 10g RAC the binaries are installed on each server.
Other wise I'd say it's NOT recommended, besides you don't save anything (execpt a cooupl of Gigs disk space).

Running BizTalk on multiple non-clustered servers. Potential serious issue

Hi,
I have just discovered what has potential to be a fairly large issue in our current BizTalk Architecture. We are running BizTalk Server 2006 R2 on 2 different servers, running Windows Server 2003 R2. These servers are NOT clustered. Instead, BizTalk is installed
to both, configured on 1 and then on the 2nd, they have joined the existing BizTalk environment. We have 1 host with 2 host-instances for say an Orchestration Host. (So 1 Orchestration Host and then 1 Orchestration Host Instance on each server), we also have
a host instance for Receive and Send on each server.
This is a problem that I have identified on an application currently in UAT:
We have a routine called 'Recovery Mode'. It doesn't matter what Recovery Mode is but what does matter is that only a single instance can go into recovery mode at the same time.
Consider this:
bool inRecovery;
while (isBroken) {
if (!inRecovery){
inRecovery = true;
// Recover
inRecovery = false;
else {
// Wait, recheck until not in recovery, or fixed.
Imagine an instance on server 1 needs to go into recovery, it first checks the inRecovery flag, gets returned false so goes into recovery, let's say this takes 5 minutes to complete. During this time, an instance on server 2 needs to go into recovery, checks
the flag, but the flag on server 2 has not been set to true.... Now I have 2 instances in Recovery...
My questions are:
1. Can I cluster 2 non-clustered servers? I'd need to upgrade from Windows Server 2003 R2 Standard to Enterprise is that possible? If so, Can I simply upgrade and cluster the servers or would I need to format the disks?
2. If no to number 1, where would you store the 'inRecovery' flag'? I can't store in a DB as there will be slight cross over where instance 2 might return false in my example just as instance 1 is writing unless I can lock it on write or something.
Some advice would be greatly appreciated.
Thanks
Rod

To answer your specific question:
1. Yes, but you would need to upgrade to at least Enterprise. Windows Server 2003 R2 Standard does not support clustering. IIRC, the upgrade from Standard to Enterprise is pretty easy, perhaps just a SKU change.
2. If you absolutely cannot upgrade Windows Server, then you'd have to store the state externally, such as SQL Server. There shouldn't be any concurrency issues if you do the check in the right sequence. Basically, begin a transaction, attempt
to UPDATE, return weather the UPDATE was successful, meaning that call grabbed the lock. If you check then update, yes, there is a miniscule chance both will return the same value but only one near-sumultaneous UPDATE will succeed.

Will it support non cluster environment.

Dear Coherent,
How will I test my configuration of oracle coherence on non clustered Oracle database environment.
Thanks,
Biplab.

There is no relation between Coherence in memory Data GRID and Oracle Db (with or not RAC)

Data Caching in a Clustered Environment

          I want to cache read-only reference/code table data that will run in a clustered
          WLS6 environment. It's a JSP application and I am storing a complete HTML Select
          Control per reference/code table data in the cache. The question is where to
          cache it? I was going to put it in the ServletContext (JSP "application" implicit
          object), but the ServletContext is not replicated. I considered using JNDI, but
          there are problems with duplicate name errors when another server who doesn't
          originally bind the object tries to lookup, change and rebind the object. I guess
          JMS Multicasting is an option, but I don't want to implement JMS just for an application
          data cache.
          Any suggestions for a simple reference/code table read-only caching strategy that
          will work in a clustered WLS6 environment?


If the data is strictly read-only, and you do not have to worry about cache
          integrity, then look at WebLogic JSP cachetag:
          http://www.weblogic.com/docs51/classdocs/API_jsp.html#cachetag
          You can use it to cache both the output and the calculations results
          (variables calculated inside the cache tag).
          The scenario will be exactly the same for non-clustered and clustered
          cases - using multicast to broadcast small invalidation messages (so the
          data can be refreshed from the database) is ok, but replicating application
          data is not (and you definitely do not want to use JNDI for this purpose).
          BTW, the initial CacheTag implementation in 5.1 (supposedly) had a 'cluster'
          scope and I assume it was multicasting fresh data after cache miss - there
          is no such scope in 6.0 implementation.
          If you still want replication you can look at javagroups:
          http://sourceforge.net/projects/javagroups/
          (distributedhashtable example).

Issue in Synchronous File Read in clustered environment

Hi,
We are using clustered environment (4 managed servers) in Unix. In a OSB 11gR3 proxy service we are using Synchronous File Read. Randomly we are getting the below error. Let us know what could cause the issue. But the same code is working fine in a single stand-alone server configuration.
Error Code : BEA-380002 , Error Reason : Invoke JCA outbound service failed with connection error, exception: com.bea.wli.sb.transports.jca.JCATransportException: oracle.tip.adapter.sa.api.JCABindingException: oracle.tip.adapter.sa.impl.fw.ext.org.collaxa.thirdparty.apache.wsif.WSIFException: servicebus:/WSDL/wsdlPathAndName [ SynchRead_ptt::SynchRead(Empty,body) ] - WSIF JCA Execute of operation 'SynchRead' failed due to: No Data to process.

I face the same issue and I have given all permissions to the folder for OS user.
Because of this error my server is not starting up . Is there any way I can undeploy this composite to get my server running.
I cant do this from EM because SOA server is failing to start up.
I have tried removing it from $DOMAIN_HOME/deployed-composites but still when i try restarting the soa server the composite comes up there. Do we need to delete the entry some where else too. Kindly help.
Thanks,
Sri.

What is RID in non clustered index and its use

Hi All,
I need help regarding following articles on sql server
1) what is RID in non clustered index and its use.
2) What is Physical and virtual address space. Difference in 32 bit vs 64 bit Virtual address space
Regards
Rahul

Next time Please ask single question in a thread you will get better response.
1. RID is location of heap. When you create Non clustered index on heap and
lookup happens to get extra records RID is used to locate the records. RID is basically Row ID. This is basic definition for you. Please read
this Thread for more details
2. I have not heard of Physical address space. I Know Virtual address space( VAS)
VAS is simple terms is amount of memory( virtual ) 'visible' to a process, a process can be SQL Server process or windows process. It theoretically depends on architecture of Operating System. 32 bit OS will have maximum range of 4 G VAS, it's calculated
like a process ruining on 32 bit system can address max up to 2^32 locations ( which is equivalent to 4 G). Similarly for 64 bit max VAS will be 2^64 which is theoretically infinite. To make things feasible maximum VAS for 64 bit system is kept to 8 TB. Now
VAS acts as layer of abstraction an intermediate .Instead of all request directly mapping to physical memory it first maps to VAS and then mapped to physical memory so that it can manage request for memory in more coordinated fashion than allowing process
to do it ,if not it will soon cause memory crunch.Any process when created on windows will see virtual memory according to its VAS limit.

Space occupied by clustered index Vs non-clustered index

I am trying to understand the indexes. Does clustered index occupy more space than a non-clustered index because it carries the information about rest of the other columns also. Could you guys please help me understand this. Thanks in advance.
svk

Hi czarvk,
Clustered index in SQL Server takes up more space than non-clustered indexes.
Clustered index arranges the way records are stored in a table putting them in order (key, value), all the data are sorted on the values of the index.
A non-clustered index is a completely different object in a table, containing only a subset of columns and a row locator to the table’s rows or to the clustered index’s key.
So clustered index in SQL Server takes up more space than non-clustered indexes.
If you have any question, please feel free to let me know.

Donghui Li
