Few Standby doubts

Hello all,
I have few queries regarding standby database.
1)Correct me if I am wrong. On primary Database Standby Redo log is required for switchover and on standby database Standby Redo log is required for
--Real time Apply
--Maximum protection or Maximum availability
Am I correct?
2)My database is in Maximum Performance mode. I set up following entry on init.ora:
LOG_ARCHIVE_DEST_2=’service=standby LGWR ASYNC’. My question is do I need to have STANDBY Redo log file on standby database in order to use LGWR transport (LGWR ASYNC)mode from primary? Without Standby redo log on standby database can it transport redo data from primary to standby using LGWR transport mode (LGWR ASYNC)?
3)I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter. But I have not changed the protection mode. I would like to know whether is there any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY"?
Thanks ans reagrds

Hi,
concerning your questions
What Version of Oracle you are using?
1)Correct me if I am wrong. On primary Database Standby Redo log is required for switchover and on standby database Standby Redo log is required for
In Oracle Release 11.2 you should have to create Standby Redolog in all protection modes.
Yes, you create on the primary side Standby Redologs if you do a role change.
2)My database is in Maximum Performance mode. I set up following entry on init.ora:
LOG_ARCHIVE_DEST_2=’service=standby LGWR ASYNC’. My question is do I need to have STANDBY Redo log file on standby database in order to use LGWR transport (LGWR ASYNC)mode from primary? Without Standby redo log on standby database can it transport redo data from primary to standby using LGWR transport mode (LGWR ASYNC)?
Yes, you should create standby redologs. ARCH transport is in Oracle 11g deprecated.
3)I have changed from the "ARCH" attribute to "LGWR" attribute of the LOG_ARCHIVE_DEST_n initialization parameter. But I have not changed the protection mode. I would like to know whether is there any impact in the behavior of the database, if we do not change the mode from "MAXIMUM PERFORMANCE" to "MAXIMUM AVAILABILITY"?
I don't understand your question. You said under point 2.) that LGWR ASYNC in is configured. But now you say LGWR ARCH.
Only in Oracle Version 11.2 it is possible to change the protection mode via dgmgrl command without restart the database.
So first of all what plattform and Oracle Release you are using?

Few errror/doubts in Primary and Standby server - Need Help

Hi All,
I am having below doubts/errors. I need help to solve all the below questions.
I configured Dataguard successfully. Now the sync is upto date using the below parameters (using 11g):
at primary:
log_archive_dest_1=
log_archive_dest_2='SERVICE=standby.123 arch'
standby_file_management=auto
at sandby:
log_archive_dest_1=
standby_file_management=auto
Still i face below messages in the alertliog. Can anybody clearly explain me all the points.
Primary:
ORA-1652: unable to extend temp segment by 640 in tablespace NEWTEMP
I get this error when my archvie destination got filled up, later we released the enough space, the archived are generating. Still i see this message once in between. Need to solve this.
Primary:
Checkpoint not complete ( i see this message very often, want to get rid of this)
standby:
kcrrvslf: active RFS archival for log thread 1 sequence (sometimes i see this KCRRVSLF)
standby:
check that the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter is defined to a value that is sufficiently large enough to maintain afequate log switch information to resolve archivelog gaps. (also get this message in between the alertlog file in standby)
Standby:
FAL[client]: Error fetching gap sequence, no FAL server specified (this is very often message. How to remove this, what needs to be added. Do i need to add the below parameters)

Need to solve this.This error has absolutely nothing to do with the handling of archive logs, the status of archivelog destination, or primary/standby. Any relation you thought you saw was pure coincidence.

Here is the very first hit I got when I googled "oracle checkpoint not complete". Tom says it better than I would have.

A quick google of that one, and it looks like it is not even an error, but rather simply an informative

In that case I would check that the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter is defined to a value that is sufficiently large enough to maintain adequate log switch information to resolve archivelog gaps.
How big is that? Well, at least bigger than it is now. Beyond that, it would have to be "large enough to maintain adequate log switch information to resolve archivelog gaps" Just play with it until you get the result you want.

Few basic doubts about accessing AM from backing bean class

Hi ADF experts,
I have just started working in ADF Faces.I made a sample search page.My page is attached to a managed backing bean. I have attached command button on my page to a custom method in backing bean class.
So on, click of button this method is called in backing bean.Now, i have few doubts:
1)How to get values of various UI beans in this event code?
2)I am accesing AM , in my method with this code:
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext extContext = facesContext.getExternalContext();
Application app = facesContext.getApplication();
DCBindingContainer binding = (DCBindingContainer)app.getVariableResolver().resolveVariable(facesContext, "bindings");
//Accessing AM
ApplicationModule am = binding.getDataControl().getApplicationModule();
iS this correct ?
3) After getting handle of am how to call my custom method in AM Class?there was "invokeMethod" API in application module class in OAF, is there any such method here?
Please help me.
--ADF learner.

Thanks for ur response Frank, actually I am from OA Framework back ground.It would be great if help us a little with ur valuble thoughts.
OA Framework also uses bc4j in model layer of framework. We have a requirement where our existing developers from OA Framework have to move to ADF to make a new application where time lines are quite strict.If this would not be possible we will switch to plain jsp and jdbc,but our tech experts say ADF Faces is the best tech.
In OA Framework, Application Module is key class for all busiess logic and Controller is used for page navigation. So, I m just trying to find the same similarity , where we write we add all event codes in custom action methods in the backing bean class of page, which we consider equivalent to process form request method in Controller class of OAF.
But there are two things, I still want to know:
1)While page render, how to call specific AM methods(like setting where clause of certain VOs)
2)In action methods, the way i described(I found that in one thread only)to access AM, what is wrong in that?Also, I went through
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
where coule of examples use similar approach to access AM from backing bean class and call custom methods of AM(Doing various, deletes etc from VOs).
3)In these methods can we set any property of beans on the page, I am asking because in OAF, generally we use PPR for js alternatives.But all properties of beans cannot be set in post event.
Thanks and Regards

How to upgrade standby doubt

hello,
I read various Oracle documents, guides and metalink notes but I still have some doubts. Perhaps I missed something.
starting env: dataguard (manual config, without broker) env with primary and physical standby in 11.2.0.1 on Linux x86_64
I don't want to go with rolling upgrades or similar; I'm on a test environment and also for production I can tolerate some downtime during the week end.
My upgrade scenario is to install sw in new oracle_home as recommended.
One note: the link provided in note 884522.1 gives a file for preupgrade (utlu112i.sql) that is not current ... I had to make a clean install of 11.2.0.2 and get the file provided inside rdbms/adin directory....
I start runInstaller with primary DB open and physical in mount with managed recovery and in sync
I install new binaries and then complete the dbua step (100% without errors)
I only had to change my log_archive_dest_2 that was
service=TESDB1DR ASYNC DB_UNIQUE_NAME=TESDB1DR VALID_FOR=(primary_role, online_logfile) COMPRESSION=ENABLE
and worked in 11.2.01. but dbua complained about syntax and so I had to change in:
service=TESDB1DR ASYNC DB_UNIQUE_NAME=TESDB1DR VALID_FOR=(online_logfiles,primary_role) COMPRESSION=ENABLE
Now I have my primary db in new version.
dbua didn't update the tnsnames.ora, so I get this on primary alert.log
Thu Nov 04 15:25:33 2010
Error 12154 received logging on to the standby
PING[ARC2]: Heartbeat failed to connect to standby 'TESDB1DR'. Error is 12154.
while at the end of upgrade, on standby alert.log I got:
TNS-00507: Connection closed
nt secondary err code: 0
nt OS err code: 0
Error 12537 received logging on to the standby
FAL[client, USER]: Error 12537 connecting to TESDB1 for fetching gap sequence

Thu Nov 04 13:23:12 2010
What are the steps to do at standby? The same as in primary:
1) install binaries for 11.2.0.2
2) upgrade db
and only at the end
3) modify parameters on both instances tnsnames.ora so that they are able again to communicate
Can the standby db stay in mount + recovery mode while upgrading?
I hope I have not to refresh the whole standby....
Thanks for suggestions,
Gianluca

What do you mean by "Do I have to manually update my .ora files?" and where Primary or Standby?When on standby I select install software only, I get a new $ORACLE_HOME/network/admin that is empty
So I presume I have to copy my 11.2.0.1 tnsnames.ora and listener.ora to the new path
And to change inside my listener.ora the line
(ORACLE_HOME = /app/oracle/product/11.2.0/dbhome_1)
matching now
(ORACLE_HOME = /app/oracle/product/11.2.0/dbhome_2)
at least for the instances I want to upgrade (if more than one)
Also, I noticed that upgrading the primary with dbua, it got as a result this kind of "strange" tnsnames.ora:
# tnsnames.ora Network Configuration File: /app/oracle/product/11.2.0/dbhome_2/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
TESDB1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = primary_server_name)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = TESDB1)
LISTENER_TESDB1 =
(ADDRESS = (PROTOCOL = TCP)(HOST = primary_server_name)(PORT = 1522))
And this listener.ora
# listener.ora Network Configuration File: /app/oracle/product/11.2.0/dbhome_2/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = primary_server_name)(PORT = 1522))
ADR_BASE_LISTENER = /app/oracle
So it seems it didn't update the network config. It has no knowledge of my standby TESDB1DR
I presume I can copy listener.ora and tnsnames.ora as configured in 11.2.0.1...
From 11.2.0.1 to 11.2.0.2 I don't think about major changes in these files... am I correct?
Thanks for your time.

Standby doubt

Hi Experts im on 11G R2 database on linux 5.4, while configuring a physical standby from scratch, remember i dont want to use RMAN, when i copy datafiles from primary to standby, is it necesarry to shut down primary and then copy datafiles ? or i can use SCP command and copy even though primary is up in read write mode ?

Hello;
"SCP command and copy even though primary is up in read write mode"
The answer to this is no.
If you want to SCP your primary you have to:
1. Create the directories for the file on the Standby server
2. Shutdown the primary database and then SCP the data files, online logs and temp files over.
If you use this method you still have to account for the standby control file and the password file.
My notes on this method are here:

Few Standby questions

Hello,
1) Should a dedicated network be used for the redo shipping?
2) On the create standby, how many parameters are mandatory?
3) What is the purpose of standby Control file?
Thanks

Hello;
1) Should a dedicated network be used for the redo shipping?It's not common but if you have either a business need or a network requirement it can be done.
2) On the create standby, how many parameters are mandatory?Not many. For Oracle 10 for example these are common, but not all all required.
FAL_SERVER
FAL_CLIENT
STANDBY_FILE_MANAGEMENT
DB_FILE_NAME_CONVERT
LOG_FILE_NAME_CONVERT
LOG_ARCHIVE_DEST_1
LOG_ARCHIVE_DEST_2
LOG_ARCHIVE_DEST_STATE_1
LOG_ARCHIVE_DEST_STATE_2
LOG_ARCHIVE_MAX_PROCESSESSeveral default just fine. But DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT are only required if the directory
structure is different or the standby is on the same server as the primary ( heaven forbid ).
3) What is the purpose of standby Control file? I like Freddie's answer

Standby doubts

Hello all,
1)Standby Redo Logs do not to be multiplexed. Is it bacause to prevent additional writes by RFS process to SRL?
2) How can I open the standby in read only mode if I have no online redo logs?
3)If standby redo logs files is not present then RFS process directly creates archive logs?

1)Standby Redo Logs do not to be multiplexed. Is it bacause to prevent additional writes by RFS process to SRL? Yes, if you configure multiplexed standby redo log files it has to write simultaneously.
2) How can I open the standby in read only mode if I have no online redo logs?To open standby database in open-mode still it wont use any Online redo log files, In read only it wont perform any read/write operations, hence no need of online redo log files. Moreover if you have duplicated the online redo log files exist but they will be in idle mode, Once you performed role transition like switchover/failover then only they will be used.
3)If standby redo logs files is not present then RFS process directly creates archive logs?Yes, it will create.

Few basic doubts

Dear All,
             Does RFC adapter use Logical system in any way?
Is there Adapter Monitoring in PI 7.0 or is it called Communication Channel Monitoring?
              Can we see the response message of RFC synchronous communication in SXMB_MONI?
           Can you please list a few transactions which execute on ABAP stack and Java Stack respectively?
Regards,
Ashish

Ashish,
>>Does RFC adapter use Logical system in any way?
Logical Sysytems are required only for IDOC transfer scenarios.
>>Is there Adapter Monitoring in PI 7.0 or is it called Communication Channel Monitoring?
Adapter monitoring is a part of Communication channel monitoring from SP17 (regardless of XI 3.0, PI 7.0)
>>Can we see the response message of RFC synchronous communication in SXMB_MONI?
Yes. But you have to enable logging for synch msg in SXMB_ADM--> Integration Engine Configuration -->Specific Information.
Add the parameter. LOGGING_SYNCH value 1.
>>Can you please list a few transactions which execute on ABAP stack and Java Stack respectively?
All transactions execute in ABAP to my knowledge.

Code Comparision using SE39, Have few fundamental doubts

Dear Members,
I am doing a code comparison using SE39.
even though some lines are identical, System is showing sign of not-identical. I don"t understand why system is doing that.
I have changed the settings to ignore Comments, Indentation and Upper/Lower case.
Also Some time System shows the line as as Not Identical and keep "$$ signs. what does this mean.
Advance thanks for your inputs.
Sunitha.

Hi Suneetha,
u go to menu system..............>settings................make changes in setting ignore uppercases or lower cases.
if the program is in the same system in Utility......> version management u can see the changes in two versions.
Best Regards,
Flavya

Few more doubts

once i clicked yes....the window closed and give message like
MASS MAINTAINENCE STARTED IN THE BACKGROUND.
So after how much time can i check to see the records deleted??? so now i should have 2100 customers (3000 i had and i hv given 900 to delete).
Where can i find the changes...and how much time will it take to display?

raghu,
at the bottom of the transaction on the status bar where you normally see the transaction code, click there after the deletion process is over. You will find the program which ran, the interpretation time and Response time. the time you see here is the time taken to complete the deletion job.
How fast can it be completed, it depends on the program logic, the calls made to database for any required access or updation, whether the program is doing a synchronous or asych updation etc.
Hope it answers your query.

Standby Database Configuration with LGWR and ASYNC

Hi,
I am running a standby database configuration on a 100MBit LAN
with the following set-up:
log_archive_dest_2='service=standby mandatory reopen=300 lgwr
async=2000'
The system is handling a lot of very small transactions, not
involving large amounts of data.
My questions are:
- What are the potential problems in using a small ASYNC buffer
like the one above?
- Does a larger ASYNC buffer influence the latency in copying
changes from the production database to the standby database -
will it buffer more changes before sending them to the standby
database?

Murlib,
I have few more doubt-
Our requirement is to configure a Standby( Physical-MAXIMUM PERFORMANCE
mode) in a place, which is 600 KM away from our primary destination.
Currently our LAN network traffic rate is 100 Mbps. but this traffic is
virtually reduced to 1Mbps out side our LAN.
Our Production Database is 24X7 and Its generating 17 GB Archive files every
day.
Since the net work traffic is slow i think, it will create some log gaps,and
also we couldn't do a point in time recovery.
We are configuring a Standby, here inside our LAN in Managed Recovery Mode
for recovery purpose and will keep a Standby there in remote place for
Reports.
and it will be recover it in every morning.If iam following this procedure,
my
log_archive_dest_2 ='service=stby ARCH NOAFFIRM' ( which is the standby here
inside our LAN and should be in MANAGED RECOVERY mode)
and i need to configure the parameters for standby in my remote location.So
my doubt is-
Shall i need to configure "log_archive_dest_n" in the parameterlist of my
Primary for that remote Standby ?
I think for manual recovery we can aviod that.But we need to eonnect it
thrrough Oracle Net
Can you please tell me the essential PRIMARY parameter list entries for this
kind of remote standby , recovering in a manual mode ?
i think the following parameter should be there -
FAL_SERVER
FAL_CLIENT
DB_FILE_NAME_CONVERT
LOG_FILE_NAME_CONVERT
STANDBY_FILE_MANAGEMENT=AUTO
STANDBY_ARCHIVE_DEST
Thanks and Regards,

Nokia Mix Radio+ subscription doubt

Can someone please clear few of my doubt regarding using nokia mixradio.
First of this is when Nokia write statement like this
"Listen to Nokia MixRadio – unlimited FREE music mixes to play now or download for later."
Source (http://www.nokia.com/in-en/support/product/mixradio/)
What does it mean ?
As per my understanding I can play at least mixes without having a subscription plan. Is it correct ?
In no than its too bad to advertise like that, but as always customer won't be able to anything about it other than regrating buying Mobile from Nokia.
Now comes the few more doubt. If I plan to buy the MixRadio+ subscription plan than,
Will I be allowed to have only offline mixes or more at a time?
Will streaming available in HD quality also or only SD quality ?
I am fan of Mix Radio and even willing to buy subscription but only if these two restriction ( limited offline mixes and poor sd quality audio) are not there.

Hi, RDhorawat. Welcome to the Nokia Support Discussions! Given the link that you have provided, please allow me to assume that you are currently in India. If not, feel free to specify your location.
Provided that you are in India, the link refers to the Nokia Music Unlimited service. This is a music service which allows the user to download unlimited music files from the Nokia Music Store within a specific period of time (3, 6, and 12 months). To avail this, your phone must have the supported variant (India & China only) and the user is using the service within the supported territory/country.
The other Nokia Music service is Nokia MixRadio+ which supports the following feature:
- Skip an unlimited number of tracks while listening to mixes
- Save an unlimited number of mixes for offline listening
- Stream mixes with higher-quality audio
- View lyrics (when available) while listening to music on my music or MixRadio
Note: This is exclusive to certain countries: Australia, Austria, Brazil, Canada, China, Finland, France, Germany, India, Indonesia, Ireland, Italy, Malaysia, Mexico, Netherlands, Norway, Poland, Portugal, Russia, Saudi Arabia, Singapore, South Africa, Spain, Sweden, Switzerland, Thailand, Turkey, UAE, UK, United States, Vietnam
Given this information, let's answer your questions in the same manner that you have presented them:
1. As per my understanding I can play at least mixes without having a subscription plan. Is it correct ? - For India & China, it will require you to have a NMU subscription to enjoy this service.
2. Will I be allowed to have only offline mixes or more at a time? Will streaming available in HD quality also or only SD quality ?
- These features are not available for your region. But for those who have MixRadio+, they can download unlimited offline mixes and can stream higher quality audio.
Hope this helps.

Oracle Apps - 9iAS : Basic doubts

Hello,
I am new to Oracle Apps and 9iAS
I have few basic doubts regarding the integration of these
Can anybody please clarify...
The middle tier of Orcale Apps is the 9iAS Application Server.
Read that Oracle9i AS Components are :
- J2EE and Internet Applications (sub-components are Oracle HTTP Server, OC4J, Web services etc)
- Portals
- Wireless
- Web cache
- Business Intelligence
- E-Business Integration
Read that middle tier of Oracle Apps has following servers
- Web server
- Forms server
- Concurrent Processing server
- Reports server
- Discoverer server (optional)
- Admin server
So, all the components of 9iAS are installed with Oracle Apps ?
If only some, then which are those ?
Where do Concurrent Processing server, Reports server etc come from as these are not the components of 9iAS ?
Are these very specific to Oracle Apps only ?
As the core database administration knowledge is required for Apps administration (for managing database tier), isn't the 9iAS knowledge required (for managing the middle tier) ?
If yes, then upto what level ?
Knowing about Oracle HTTP Server, Apache server, Web cache, OC4J etc etc is required ?
Please suggest some links / documents related to all these ?
I found a couple of them on metalink & OTN, but not very useful !
Thanks

9iAS consist of Apache and an Oracle database on the middle tier.
The other components come from the developer suite.

Whats the basic difference between OracleBase, OracleInventory and OracleHome ?

Where are trace files, pfile, dump files, archive files, etc stores. I found control, dbf and log files under
/u01/app/oracle/product/10.2.0/db_1/oradata/orcl/
Can you guys please help me understanding the Oracle File Structure on Linux. Its bit complex yet interesting. Waiting for some guides.
Edited by: sachinaddy on Nov 29, 2010 11:54 PMORACLE_BASE is an environment variable used as base directory for an OFA installation. On Unix systems, this is usually /app/oracle or /u01/app/oracle.
ORACLE_HOME refers to either:
a directory where the Oracle software is installed; or
an environment variable pointing to the directory where the Oracle software is installed.
Check current value:
$env | grep ORACLE_HOME
$env | grep ORACLE_BASE
ORACLE INVENTORY
inventory stores information about all Oracle software products installed in all Oracle homes on a machine, provided the product was installed using OUI or oraInst.
you can find the bdump,udump,cdump folders in the location
