Using loopback filesystems in a cluster

Hi,
We need to share a filesystem on one of our zones to another zone on the same server. Obviously we can't use NFS so i thought lofs might be an option.
The problem is is that the directory they want sharing is on a clustered filesystem as is where they want to mount it. So if one of those 2 servers fails over the share will stop working.
Any ideas about the best way to set this up?
Thanks
Daz

Do both zones need to be able to access the file system read-write or is one read-only? You seem to suggest that the file system is a clustered one. If so, I think this can be done with zone clusters, but one zone gets to access the file system read-only. I've not tried this, which is why my memory is a little vague.
If both need read-write access, then I can't really see how it can be done.
Regards,
Tim

When not to use loopback?

Hi guys,
It seems very simple question, but it made me go thinking and thinking and decided it would be worthwhile to share it here with you.
I am building a small network with one core switch doing all inter vlan routing and connecting to two edge routers (these routers are used for different purpose).
I am planning to use a management vlan having all the switches as part of it. And I was thinking of using loopback interfaces on the routers and use static routing so the core knows where they are located.
My question (which may seem stupid here ) was to ask whether having loopback here would be really worthwhile? or if there is a better way in regards to management of the network devices?
Thanks,
Mo

having a loop back really only makes sense if you have more than 1 path into the router. If you have a single network connection into the switch and that connection goes down, having a loop back wouldn't help much.

          Admin server is not supposed to participate in the cluster. I wouldn't
          deploy anything on the admin server.
          I think my personal preferene would be connection factories to the cluster
          and use distributed destinations.

Is it possible to use Loopback in Logic pro 9?

I try to make some goods loops with Logic pro 9, but for live events it's very bad. In mainstage there is a good Loopback, but I need to make some mixage in the same time, and I prefer to use Logic. Is there a solution to use Loopback in Logic Pro 9?
Thank's

Hi
The Loopback plugin is only available in Mainstage, & not within Logic.

Is there anybody really using Loopback ??

Hi,
I'm using latest version of MainStage ( 2.1.1 ) in 32-bit mode and I cannot figure out how to use the overdubbing feature in Loopback plugin. First record is always fine, but overdubbing is normally failing: maybe no record or just starting late or at wrong time.
Also problems undoing last record or even clearing the tape I have found sounds not deleted.
Is there anybody using Loopback at all ??
Regards,
Joan

I'd also like to hear who is successfully using Loopback during live performance. I had it hooked up to some footswitches and was learning my way around it, but was finding it too temperamental to risk using for using looping in my live solo performances. As you know, timing has to be accurate, and operation flawless.
I have resorted back to using my Boomerang III hardware looper, which I am very comfortable with. I use Mainstage for all my other guitar effects (as well as vocal, sax, and WX5). I also use Mainstage to route what goes into the Boomerang, and to control loop volume in the mix. This combination has been stable and predictable for me so far, which is crucial for live solo performance.

Sparse Root Zone using loopback refuses to shutdown

New to zones, so been following along with the System Administration Guide: Solaris Containers-Resource Management and Solaris Zones doc from Sun (#817-1592). Everything seems ok with a plain jane zone, but I've run into trouble trying to use the loopback method to mount some other filesystems.
The zone in question refuses to shut down no matter what method I use, and seemingly points to an RPC issue.
using zlogin from the global zone, I get this, and it just hangs:

I take that back - my other test zone also seems to be giving me issues. I initally issues a zone halt to shut it down, which seems to work for all zones. But is that recommended?

Listener setup when using multiple databases on same cluster

Hi,
In our 2-node RAC cluster, we have 5 databases running on the same cluster. Since we are using SCAN listener on port #1521, does this mean db port# for all databases is 1521?
If I decide to use a unique port# (other than SCAN port#), what are the choices?
ENV: 11gR2, 2-node RH 5.x
Thanks!

The answer to your question depends on how it was configured.
My recommendation ... run some tests and see if that is the way it was done.

In labview 64bit, Use PostLVUserEvent with user data cluster, unhandled exception occured.

My labview is Labview 2009 64 bit, I use PostLVUserEvent to post message with cluster data to labview. The following is the struct in dll:
typedef struct {
   int32 dimSize;
   uInt8 elt[1];
} TD1DINT8;
typedef TD1DINT8 **TD1DINT8Hdl;
typedef struct{
   int32       interruptSource;
   TD1DINT8Hdl portData;
}DIInterruptData, *PDIInterruptData, **HDIInterruptData;
In labview, the DIInterruptData corresponds to a cluster, in which there are a int32 integer and a uint8 array.
It works well in labview 32bit. But in labview 64bit, unhanlded exception occured. why?

Using dbca to extend RAC cluster error

Hi all,
I'm trying to extend my 11gR2 RAC cluster (POC) using the Oracle documentation (http://vishalgupta.com/oracle/docs/Database11.2/rac.112/e10718/adddelunix.htm). I've already cloned and extended Clusterware and ASM (Grid Infrastructure) to the new node, as well as cloned the RAC database software to the new node. When I run the below statement to have dbca extend add a new instance on the node for the RAC I get the error shown:
CMD:
$ORACLE_HOME/bin/dbca -silent -addInstance -nodeList newnode13 -gdbName racdb -instanceName racdb4 -sysDBAUserName sys
-sysDBAPassword manager123
ERROR:
cat racdb0.log
"Adding instance" operation on the admin managed database racdb requires instance configured on local node. There is no instance configured on the local node "newnode13".
I set ORACLE_HOME before running dbca, and I've also tried setting ORACLE_SID to both racdb4 and racdb, no change. My environment is below, any help is appreciated.
OS: SLES 11.1
Database: 11.2.0.1
Existing Nodes: node01,node02, node03
New Node: newnode13
DB Name: racdb
Instances: racdb1, racdb2, racdb3
New Instance: racdb4
Thanks.

Silly me, I was running the command from the new node instead of an existing node. I guess it was a rough weekend after all. Thanks all!

Using UMS on a Glassfish cluster - how to support session replication ?

Hello,
I have deployed the imqums.war in a Glassfish cluster but can not use the session replication.
The UMS uses sid as client session identifier. If the client session is is created on node 1, when the call hits the node 2 it gets:
com.sun.messaging.ums.service.UMSServiceException: javax.jms.JMSException: sid is not authenticated. Use login to get a new sid, expired/invalid sid=4-LTE2NTA5ODMzMTU=
at com.sun.messaging.ums.service.ClientPool.getClient(ClientPool.java:157)
at com.sun.messaging.ums.service.SendServiceImpl.commit(SendServiceImpl.java:244)
at com.sun.messaging.ums.service.UMSServiceImpl.commit(UMSServiceImpl.java:234)
at com.sun.messaging.ums.core.UMSServlet.doSimpleMessaging(UMSServlet.java:786)
at com.sun.messaging.ums.core.UMSServlet.doPost(UMSServlet.java:633)
Can you provide advise how to obtain session replication for UMS calls ?
Thank you,
Cristina

There is an example here,

It was run on WebLogic but should be runnable on Glassfish without too much effort. (if you port it, please submit your changes to the wiki or bugzilla).

RAC 10gr2 using ASM for RMAN a cluster file system or a Local directory

The environment is composed of a RAC with 2 nodes using ASM. I have to determine what design is better for Backup and Recovery with RMAN. The backups are going to be saved to disk only. The database is only transactional and small in size
I am not sure how to create a cluster file system or if it is better to use a local directory. What's the benefit of having a recovery catalog that is optional to the database?
I very much appreciate your advice and recommendation, Terry

Arf,
I am new to RAC. I analyzed Alejandro's script. He is main connection is to the first instance; then through sql*plus, he gets connected to the second instance. he exits the second instance and starts with RMAN backup to the database . Therefore the backup to the database is done from the first instance.
I do not see where he setenv again to change to the second instance to run RMAN to backup the second instance. It looks to me that the backup is only done to the first instance, but not to the second instance. I may be wrong, but I do not see the second instance backup.
Kindly, I request your assistance on the steps/connection to backup the second instance. Thank you so much!! Terry

Poll the new or changed records use DB Adapter in OSB Cluster

Hi！
I have an OSB Cluster which is included two servers: osbServer1 & osbServer2.
I need to poll a view V_TMS_GOODS, and I use the "SequencingPollingStrategy" to implement it. The following is my JCA config:
<adapter-config name="getGoodsInfoFromERP" adapter="Database Adapter" wsdlLocation="getGoodsInfoFromERP.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/DB/shaphar" UIConnectionName="shaphar" adapterRef=""/>
<endpoint-activation portType="getGoodsInfoFromERP_ptt" operation="receive">
<activation-spec className="oracle.tip.adapter.db.DBActivationSpec">
<property name="DescriptorName" value="getGoodsInfoFromERP.VTmsGoods"/>
<property name="QueryName" value="getGoodsInfoFromERPSelect"/>
<property name="MappingsMetaDataURL" value="getGoodsInfoFromERP-or-mappings.xml"/>
<property name="PollingStrategy" value="SequencingPollingStrategy"/>
<property name="SequencingColumn" value="LAST_MODIFY_DATE"/>
<property name="PollingInterval" value="60"/>
<property name="MaxRaiseSize" value="50"/>
<property name="MaxTransactionSize" value="unlimited"/>
<property name="NumberOfThreads" value="1"/>
<property name="ReturnSingleResultSet" value="false"/>
<property name="SequencingTable" value="EDI_TRANS_TIMELOG"/>
<property name="SequencingTableKeyColumn" value="TRANS_TYPE"/>
<property name="SequencingTableValueColumn" value="LAST_TRANS_DATE"/>
<property name="SequencingTableKey" value="V_TMS_GOODS"/>
</activation-spec>
</endpoint-activation>
</adapter-config>
The question is:
If I check the "Distributed Polling" box in the JCA Configuration Wizard, the sequence table will have two records for the polling Sequencing, just like the following:
TRANS_TYPE LAST_TRANS_DATE
V_TMS_CLIENT 2011/12/19 16:23:36
V_TMS_CLIENT 2011/12/19 16:23:36
If I don't check it, the records is single
And weither I check "Distributed Polling" box or not, the two servers will poll the view twice(one server one times); For example: There are one thousand records in this view, but all the records will be polled twice by the osbServer1 & osbServer2. Finally the client will get tow thousand duplicate records。
So, how can I make a balance with the two servers or use the one server to execute the polling?
Thank you for your help!

aren't the default cluster aware settings enough for this ?

you could enable a few in the adapter wizards

Using AQ Topic in OC4J Cluster

Hello,
I want to load balance messages from an AQ JMS Topic to an OC4J JEE application running in an AS Cluster. I have that setup:
AQ: Topic / Durable Subscriber -> OC4J: 2 Containers
Comming from the BEA JMS terminology I used to configure a "Messaging Bridge" (singleton) which had managed a durable subscription to that topic. The "Messaging Bridge" then load balanced the incoming messages to local destinations using a "Distributed Destination" to each logical JVM.
Is here somebody how had before a similiar scenario? What's the concept of "Distributed Destinations" in OC4J?
grüße,
\thomas

This forum is "DATABASE >> AQ"
In what way does your question relate to the database and what version if it does?

Different used space for CSV in cluster manager / explorer

Hi everyone,
in our Hyper-V Cluster consisting of two 2012 Servers we have got the following problem:
The used disk space in windows Explorer is roughly 1TB less than the used disk space which is shown in the Failover Cluster Manager. In other words: The CSV is nearly full and I don't know why.
Diskpart, failovercluster Manager and every disk tool I tried is showing 6TB as disk size and although Explorer is showing only 5TB data the cluster is showing only 100GB free.
any help?
thanks,
Michael
