Why remote listener is used in RAc environment

why remote listener is used in RAc environment

I'm sure there is something in some concepts papers anywhere on tahiti.
But as I'm as lazy to search as you are, I will try to answer:
local_listener is the listener which serves the instances which register to it (as local_listener).
remote_listener(s) should be all the listeners which serve the other instances belonging to the database.
every pmon tells all the local and remote listeners the load of the system where it resists.
In server side load balancing, the listener will redirect the client to the listener on the system with the lowest load.

Any major differences of exadata database, listener, processes than regular RAC environment?

I would like to ask for any input regarding any major differences of exadata database, listener, processes than regular RAC environment.
I know now the exadata not only have SCAN listener, but a lot other listeners. can expert here provide more details?
Thanks

We will use zfs to do backups, is that possible for the initiband listener to communicate with ZFS? where I can find documents for zfs?
The SDP (Infiniband) Listener is for client connections connecting to the database on Exadata over the SDP protocol on the Infiniband network. You should use the Infiniband network to connect the ZFS to Exadata and mount the ZFS shares to the Exadata compute nodes using DNFS; but this doesn't use the SDP listener because there is no database connection originating from the ZFS you are just backing up your databases to it. See the "Oracle ZFS Storage: FAQ: Exadata RMAN Backup with The Oracle ZFS Storage Appliance (Doc ID 1354980.1)" MOS note for good information and references regarding backing up from Exadata to ZFS.
Plus how do I know we have exalogic? I dont think we have one, but is there a way to check to be sure?
Exalogic is another of Oracle's engineered systems. It contains integrated compute, network and storage - similar to Exadata - but is used for running application environments, specifically for fusion middleware (e.g. Weblogic) applications, instead of databases. It uses a ZFS storage appliance for the storage, as opposed to the storage cells on Exadata, and for virtualized environments uses the Exalogic Elastic Cloud software. You would know if you have one.
So basically after oracle engineer installed onecommand and created sample database, as oracle dba, we can dbca to create a database just like regular RAC environment? There is nothing specific on exadata perspective?
Yes... Oracle on Exadata is still the same RDBMS - same Oracle Enterprise edition with the RAC option. The Exadata difference comes with the hardware integration and the storage cell software... the database software is the same.
Another question is do I have to configure exadata specific parameters in order for all those features of smart scan, storage index, comrpession, etc work?
Some Exadata features are mostly "black box" and work without any configuration others may take some configuration or tuning to take advantage of. For example, storage indexes are created dynamically on the storage cells... there is not much you can do to control them. For smart scans you need full table/index scans with direct path reads. So you need to tune for direct path reads. HCC requires setting up your tables/partitions to compress at one of the HCC compression levels and using direct path loads.

Tnsname.ora and listener.ora files in RAC environment.

Want to clear my concept regarding
tnsname.ora and listener.ora files in RAC environment. Is there any good notes on Metalink for that?

Check this metalink note, it covers specific RAC issues:

Questions on sqlnet.ora, listener.ora files in RAC environment.

Experts,
I've some confusion with below files in RAC environment.
sqlnet.ora
listener.ora
These files are available in two locations: <GRID_HOME> & <DB_HOME>.
My questions:
1. Why do we have two versions of files ?
2. When I query lsnrctl status from BOTH the homes, it says it is using listener.ora from <GRID_HOME> as shown below.
Listener Parameter File D:\app\11.2.0\grid\network\admin\listener.ora
3. What is the use of files which are in <DB_Home>
4. If you make some changes to listener using "Netmgr" tool, we expect it will update listener.ora in <GRID_HOME>. Interestingly, it is changing the contents of listener.ora in <DB_HOME> .
Can anyone please clarify it ?
Thanks in advance.

1. Why do we have two versions of files ? In the past, the CRS s/w did not include ASM (ASM did not provide support for cluster voting and registration disks). Thus the networking components such as SQL*Net and the Listener were not part of the CRS installation.
With Grid Infrastructure, ASM supports cluster voting and registration disks and is recommended to be used for that (as oppose to the old style of raw disks or using an external cluster-based cooked file system like <i>ocfs</i>). And with ASM comes the SQL*Net networking layer and s/w (such as the Listener). As ASM ships with Grid Infrastructure, it now also includes the same networking layer as what the RDBMS installation will. Thus both <GRID_HOME> and <DB_HOME> will contain the same networking components.
However, only a single Listener is for example needed. And that can only run from a single base location. So for operational use, only one version will be actively in use.

Oracle RAC 10g - Remote Listener

Hi DBAs,
In Oracle 10g RAC env, I see the remote listerner as well as local listerner. Can anyone throw some light what is the use of Remote Listener. Can we use only Local Listener.
Thanks
-Samar-

If you configured the dedicated server mode using the DBCA Connection Mode tab on the Initialization Parameters page, then DBCA automatically configures the LOCAL_LISTENER parameter when the listener uses a nondefault address port.
If you configured the dedicated server mode by setting the REMOTE_LISTENER initialization parameter, then you must also configure the instance-specific LOCAL_LISTENER initialization parameter.
For example, to configure the LOCAL_LISTENER parameter, add the following entry to the initialization parameter file, where listener_sid is resolved to a listener address through either a tnsnames.ora file or through the Oracle Names Server:
sid.local_listener=listener_sid
The following entry should be in your tnsnames.ora file:
listener_sid=(address=(protocol=tcp)(host=node1-vip)(port=1522))

Cloning a RAC environment using ASM to a single node.

Hi partners,
I would like to know if, there is any procedure to clone a RAC environment with Ebusiness Suite using ASM, OMF and raw devices to a single node database?
I know, it can reached using Rapid Clone, but I would like to know, what are the needed steps to clone the database which is using ASM and raw devices, I am thinking to recrate manually the controlfiles.
Also, I think that I will need to clone firstable the ASM instance, and then try to clone the database.
I have looking at Metalink, but I haven't found any Note about that.
Any advice or help will be really appreciated.
Thanks in advance.
Kind regards,
Francisco Mtz.

Cssd does not start in non-RAC environment Thus we can not bring up ASM

Non-RAC environment
ASM version = 11.1.0.7
HP-UX Itanium 11.23
After power outage, CSSD does not start on non-RAC environment
Running as root "/sbin/init.d/init.cssd start" does not start cssd
Oracle support tried "$ASM_HOME/bin/localconfig delete" and "$ASM_HOME/bin/localconfig add"
but it did not start CSS
Oracle support tried "$ASM_HOME/bin/localconfig reset $ASM_HOME"
It started the CSSD and the "crsctl check css" came back with CSS is healthy
But around 1 minute later it rebooted the server and when it came up again CSS does not start.
They checked /etc/inittab and it looked fine.
Before the reboot we saw this message in the /var/adm/syslog/OLDsyslog.log:
Cluster Ready Services completed waiting on dependencies
Again it is a NON-RAC environment. We only need CSSD for ASM. We do not have CRS installed on this server.
Our test system has been down for a week and we did not get the resolution from Oracle support yet !
Any pointers are greately appriciated.
Thanks,
Dzung

Is a gateway mandatory for RAC environment?

Question:
Is a gateway mandatory for RAC installation, general on RAC environment?
*..when yes, why?*
Many thanks
I make this test with my only one RAC node
1. Run with gateway:
[oracle@linux1 ~]$ crs_stat -t
Name           Type           Target    State     Host
ora....SM1.asm application    ONLINE    ONLINE    linux1
ora....X1.lsnr application    ONLINE    ONLINE    linux1
ora.linux1.gsd application    ONLINE    ONLINE    linux1
ora.linux1.ons application    ONLINE    ONLINE    linux1
ora.linux1.vip application    ONLINE    ONLINE    linux1
ora.orcl.db    application    ONLINE    ONLINE    linux1
ora....l1.inst application    ONLINE    ONLINE    linux1
ora....test.cs application    ONLINE    ONLINE    linux1
ora....cl1.srv application    ONLINE    ONLINE    linux1
[oracle@linux1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node linux1All thing seem correct!
2. run without gateway (blank setting):
[oracle@linux1 ~]$ crs_stat -t
Name           Type           Target    State     Host
ora....SM1.asm application    ONLINE    OFFLINE

ora.orcl.db    application    ONLINE    OFFLINE
ora....l1.inst application    ONLINE    OFFLINE
ora....test.cs application    ONLINE    OFFLINE
ora....cl1.srv application    ONLINE    OFFLINE
[oracle@linux1 ~]$ srvctl status database -d orcl
Instance orcl1 is not running on node linux1Something is false!

By default, the server's default gateway is used as a ping target during the Oracle RAC 10g VIP status check action.
Upon a ping failure, Oracle will decide that the current interface where the VIP is running has failed, and will initiate
an interface / internode VIP failover.
In above case, we used just one node for CRS installation, so the VIP coudn't failover to other nodes and thus reported additional error like :
CRS-1006: No more members to consider
CRS-0215: Could not start resource 'ora.dbtest2.vip'.
Try ->
A parameter FAIL_WHEN_DEFAULTGW_NOT_FOUND in the file
$ORA_CRS_HOME/bin/racvip to address this problem.
The following steps will fix the VIP starting problem for above mentioned scenario.
1- stop nodeapps
2- As root,
vi the script $ORA_CRS_HOME/bin/racgvip and change the value of
variable FAIL_WHEN_DEFAULTGW_NOT_FOUND=0 .
3- start nodeapps and you should see the resources ONLINE
You may proceed with netca and dbca to create a RAC database after this.

Listener as bottleneck on RAC?

Hello *,
global topic: configuration connection load balancing on Oracle RAC with two nodes
Oracle 10.2.0.1 RAC with two nodes
the service is configured as "prefered" on node 2/instance 2 and "available" on node 1/instance1
the listener on node 2 is set offline (for testing)
the listener on node 1 is running
both instances on node 1 and two are running
when I try to connect via the service, I got the response that the listener is not running
is this the normal behavior?
can I configure the first listener on node 1 to connect to instance 2 as well?
and the second listener on node 2 to connect to instance 1 as well?
Thank you reading an anwering!
Christian

The problem still persists:
I changed the remote listener parameter:
alter system set remote_listener= LISTENER_TCOMM2 sid='1';
alter system set remote_listener= LISTENER_TCOMM1 sid='2';
# Error message while listener of node two is offline

Why can't i use the radio on my nano 7g with bluetooth

why can't i use the radio on my nano 7g with bluetooth. i wanted to use wireless feature at work but i only use the radio at work , so i bought bluetooth stereo headphones by plantronics, got the backbeat 903, at wal-mart . got home got it all set up and works fine but not for radio , i'm so dissaponted and am thinking i might take them back and continue using the wire ware , but then again i like listening to my podcast while doing dishes and chores at home so the bluetooth would be better for that .

i have sent a feedback form to apple about this problem . i hope that they work on a sulotion for it .

Why doesn't SAP use SAPUI5 for this and that

This is my personal opinion about this topic! Again and again I stumble about this and now I want to share some of my thoughts about this topic. I want to share this from a point of view, when I was not a SAP Employee - I worked at a SAP Partner company - because this best reflects the view from the outside.
1. SAP "wants" us to use SAPUI5
I don't think that "wants" is the right word - the right word is offers! In terms of: hey now even included in your license and open sourced (because you wanted it so). Look - we build sooo many Fiori apps with it - and put in some great enterprise features (right to left, accessibility, translation, ...) and it is responsive. So if you want to build Fiori-like "apps" - there you go - this is your technology to go! This is what I understood.
I was very very very happy that it was build with open standards. But the main point for me another thing - (because I worked with Sybase Unwired Platform and SAP Mobile Platform) OMG an open data protocol!!! OData FTW! I could use ANY front-end technology and consume SAP data - the protocol is REST based - a dream came true. And so I did - yes I played around with Sencha Touch and OData, I used data.js and used it in a standard HTML5 application. We played around with an iOS application we already had and consumed the data. I feed the data into d3.js. I prototyped around with SAPUI5 and I have build apps with it. Brilliant, so I could choose whatever UI technology I wanted.
I always had the feeling, that SAPUI5 was meant for B2E applications - and building many of that - and they should look and feel the same and I can theme the apps. I can use it when I want to make my applications SAP like - so that the user thinks the apps are all the same and everything fits nicely into the Fiori launchpad - great if you want to build partner apps. In my ex company we won a SAP Pinnacle Award - for a native iOS app, no SAPUI5 in sight - but we have received an award, so SAP did not "want us" to use SAPUI5 ;-)
2. Is it the right UI technology for everything?
At my ex-company I was dealing with mobile applications and web apps. I always knew that I get the best user experience when I write a real native application and if you want it to look like in a very specific way with awesome UI --> you would not do it with a write-once-run-everywhere HTML5 super-styled wrapped (phone gap/cordova) app - you would write the apps for the specific platform and it should feel like it was written for the platform. SAP offered us the SAP Fiori Client that I could enhance the user experience for the Fiori apps, but I was never told to use SAPUI5 it for everything.
The same discussion goes on with: why was the new SAP website not build with SAPUI5, or the UX Explorer (eat your own dog food), or a useful internal app - why Angular, or the other way around why do we even use SAPUI5 and not Angular JS itself. Back to the past - SAP did never tell me to build a website with it, or to build something tiny and small with it (a widget) - or to enhance parts of a website with it - or to build something super-specific with it.
And yes maybe the UI in a mobile app was not SAPUI5 but do you know if it uses Gateway with OData or the SAP Mobile Platform, was the API managed with Apigee, was HCI involved in getting the data from different sources, was it maybe wrapped with SAP Mobile Secure, did it maybe use a HANA backend or some of its features (predictions, text analytics, ...) - are some backend parts maybe hosted on HCP - who knows? So yeah, maybe other SAP technology was involved which you don't see, but in the end it made your life simpler.
Instead of arguing around why this and that was used for this and that - can we save our energy and instead look at the result - which is all what counts - that it was the right UI technology with the right user interface which makes the user happy? I stated something like - does Google use AngularJS for everything? Nope. They offer us something great we can use. Right, maybe AngularJS is not as important for Google like SAPUI5 is for us. But we have something with which we can build our day-to-day business apps with and we do so.
3. We missed great opportunity in not using SAPUI5 for this and that
Let's think about how projects are going: you want something, you look at the costs, you choose most efficient option. Yes this could mean reusing an existing native application which was written long ago and you pimped it up. Or you had outsourced it to a company which wrote a similar app. Or you bought the source code. Or you have some cheap internal staff which could do it (students, trainee), or you could outsource it cheaply. Or all you have is people with experience in this and that technology. Or it must look in a very very specific way (because marketing says so) and you go native. Or it maybe should even differentiate itself and should look NOT like a Fiori app. And no - I don't think - this is my employees view - we are not for example an event app producer. We normally build business applications. And I don't think that we can write an app from scratch "just" for an event in a certain technology. Yes it would be nice if this and that would use SAPUI5, I think if it would be possible in terms of time and costs and UI wishes and hundreds of other factors we would do it with SAPUI5.
Working at the partner SAP showed me over 50 Fiori apps, now hundreds of Fiori apps are released. SAP now showed that SAPUI5 is going big with S/4HANA. We have seen the Simple Finance solution. I was walking around at the CeBIT this year and I was impressed myself which cool apps and screens have been shown with SAPUI5. I used the SAPUI5 app on a Samsung Smart Watch myself. The SAP Web IDE itself is built with SAPUI5 in its heart. I don't need any other "proves" that SAPUI5 is great. I have seen great use cases for it, but I also know myself when I would use other stuff.
4. My conclusion
There is never every anything which can cover all different use cases. One-size-fits-all clothes also does not fit for everyone even if it says so. If someone creates something great don't judge it by the UI technology. Judge it by the experience and the value it creates. There are reasons why this and that was chosen. Use what fits your needs best with your requirements. Make the end user happy!

Hey Denise,
Thanks for pulling this discussion into SCN. Makes it much easier to discuss compared to Twitter. But I also have to apologize in the beginning that my answer now exceeds 140 characters by 50 times.
Let me share my thoughts and personal opinion as well. I will try to look at it from a strategic point of view, as you – as the technical UI5 expert - have already covered the technical perspective.
SAP recommends using SAPUI5 where it fits to customers’ requirements
Let me begin with a clear statement from my perspective: It makes no sense that SAP takes customer decisions.
Of course, customers expect SAP to help them with their strategies and decisions and of course we are helping. But at the end, the decisions have to be taken by the customer who needs to take the specific conditions of the company into account. The most important condition in the context of UX is the end user. But we shouldn't forget the business strategy as the most important influence factor. I’m not saying that technical decisions are completely unimportant, but I would like to point out that other things are more important for a company.
As a result, it wouldn't make a lot of sense if SAP would just want every customer to use SAPUI5. To me, customers need recommendations leading to solutions that satisfy their needs and requirements.
There is not that one UI technology that serves all needs
This headline might be a challenging statement and I can already imagine reactions to it. But in fact I can confirm this sentence easily. You always have to combine different technologies. Some of them are from SAP others not. The selection and combination of these technologies is different from customer to customer because the requirements are different. There are still reasons to use Web Dynpro ABAP and I’m still recommending SAP NetWeaver Business Client, POWL (Power Lists), WDA Chips, FPM based on the given environment of the customer. And obviously there are also reasons for UI5.
SAP already proves the usage of SAPUI5
In general, I see two different use cases here: Developing custom applications vs. adopting applications from SAP.
In the one case, customers want recommendations on development environments and UI technologies that consider their development requirements and existing conditions (e.g. existing skills, given implementations). SAPUI5 is a great UI technology and there are some special aspects that make the decision obviously easy. If I want to create simple business applications that can be connected with my SAP system easily, especially in combination under responsive conditions on multiple devices and targeted for casual and/or occasional users UI5 might be the right choice for many. Exactly this pattern is what many customers are searching for these days. So, the recommendation for UI5 comes quite often.
Whether or not SAP proves the usage of SAPUI5 in their own world is to me more connected to the use case where customers want to adopt SAP applications. And in deed, SAP is using SAPUI5. There are hundreds of SAP Fiori applications that have been built with SAPUI5 and there have been a lot of other applications developed using SAPUI5, too. And again, there is a huge need for applications for casual and/or occasional users, so that’s a big reason for SAP to create such applications.
Websites vs. Business Applications
This discussion was triggered by some statements in twitter, that SAP sites such as sap.com, SAP UX Explorer or the latest mobile conference app are not developed using UI5. Actually I see these to be websites but not business applications. I have never told a customer to build a website in UI5 and I would continue to do so.
Maybe we need to discuss the difference between a website and a business application. I guess it is not easy to find a common understanding here, as the borderlines between several worlds have disappeared in the last years.
Some years ago it was more or less easy to differ between:
Native desktop applications running on a specific desktop OS
Native mobile applications running on a specific mobile OS
Browser-based applications running in specific browsers
Websites, basically running on many browsers
In the first three categories we saw business applications. 1 and 2 were selected especially when specific functions of the device and OS where needed to be accessed (for example the camera of the mobile device, the fast rendering capability of the desktop). 3 was also used for business applications but in most cases on desktop browsers.
Today, one can develop browser-based applications that look like native applications and even can access the devices like native applications. Responsive design breaks the borderlines even more. Now, browser-based content can be rendered perfectly on a desktop browser as well as on a mobile phone and a user might even not be able to judge whether it was originally intended to be developed for the one or the other.
So maybe there is no big difference anymore between websites and browser-based applications. But there is still a difference between browser-based applications and browser-based business applications, where additional requirements such as integration into business systems are drivers. Here I see SAPUI5 as a very cool UI technology.
That’s just my 2 (personal) cents,
JJ

Unable to access remote database object using database link

Hi all,
I have created a database link to a remote server
SQL> create database link remote_link connect to lax_dba identified by lax_dba using 'abc.corp.com';
database link created
when i am trying to access any table of lax_dba
sql> select * from laxtab@remote_link;
i am getting this Ora error
ORA-12514: TNS:listener does not currently know of service requested in connect
I need your help please to solve this issue
Thanks n Regards
Laxman

The database server where you defined the link (not your PC) has resolved 'abc.corp.com' to a server/port/service combination using its tnsnames.ora, sqlnet.ora and possibly ldap.ora settings. You can try
tnsping abc.corp.comon the server (as ReubenC suggested) to see what it's attempting to connect to. (It's important to do this on the database server and not on your PC as they will have different tns settings etc.)
It has then found the server and found a listener running on it (so you're getting close), but that remote listener doesn't recognise the service you're asking for. It might be something like the '.com' suffix.

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?

The documentation on INSTANCE_NAME in the 10gR2 Reference says :
"In a single-instance database system, the instance name is usually the same as the database name."
(this after
"In a Real Application Clusters environment, multiple instances can be associated with a single database service. Clients can override Oracle's connection load balancing by specifying a particular instance by which to connect to the database. INSTANCE_NAME specifies the unique name of this instance.")
This would imply that setting INSTANCE_NAME in non-RAC is ignored. The usage of the word "usually" is weak.

How to create DIR/File on a raw device in RAC environment.

Hi all,
I use a shell script to create DIR and File on a raw device also it creates schema and tablespaces.
I am facing problem in creating DIR and Files on raw device.
One more thing, can multiple tablespaces be created on a raw device.
Thanks & regards,
Sanjeev

Thanks for the response. Please help me further.
About the Script - It asks for the path for creating DIR and uses shell command to create DIR. Later same path and DIR name is used to create Oracle DIR. Now in place of absolute path raw device name is passed. The same script is also used for creating tablespaces and schema.
There is second script that is .sql script that creates external table in the newly created schema. All this has been working fine on single instance Oracle server. we have tested many times but fails in RAC environment when we use raw device.
Question is - If I use filesystem will the external table's flat files and Directories be accessible to all the instances.
I have one application written in java that would be clustered and running on these oracle servers. This application would be accessing those external tables and their flat files. Will there be a problem accessing these flat files accross the instances.
Regards,
Sanjeev.
