Standby Database and Server Mode

Hi gurus,
Can the client TNSNAMES.ORA file specify Server=Shared for a primary and standby configuration? Or does it have to be Dedicated to make the switchover/failover work?
Thanks a lot.
Ben

as document says
The connect descriptor must also specify that a dedicated server be used.

Running a physical standby database in noarchivelog mode

Primary Database: 2 node rac cluster, 11.2.0.2 GI and RDBMS
Standby Database: single instance 11.2.0.2
OS: AIX 7.1
Hello,
I'm in the process of implementing a data guard standby system. To make this system simpler to admin, I want to run the standby database in NOARCHIVELOG mode. This standby is used only as a mirror of production (to be copied to a 3rd site for separate user activity) and will never be switched to active mode. Maintaining another set of archive logs seems to be redundant to me and another point of failure, so I want to disable archiving. I wanted to ask if any of the DG experts on the forums have ever had experience with this? Does anyone know if this is recommended? I've searched the Oracle Data guard documentation online... it says that the primary obviously needs to be in archive mode, but I'm not seeing anything specific about the standby. Please let me know if anyone has experience with this.
Thanks

Hello again;
If this is the case, then I have nothing to worry about here. Does that sound right to you?Yes.
For this :
b) monthly, shutdown this system and copy it to a 3rd site to host a separate set of business activityI would consider RMAN Duplicate in which case you may avoid the shutdown.
And for this :
resync the "mirror" with productionAll you have to do if DEFER the primary to the standby, then ENABLE and Data Guard will catch up.
--- Will post a detailed example here in a moment.
Right at the first of the year they wanted to work on our Primary server room ( Power ). What I did was switchover to the Standby but I kept log_archive_dest_state_2 on the new primary set to DEFER. Then I shutdown
all the databases at the Primary site. At the end of work two days later I started the databases at the Primary site in standby mode. Switched log_archive_dest_state_2 to ENABLE. When the databases were back in SYNC
I did another switchover and it was done. I used TAF and none of the users even noticed.

Starting Physically Standby Database in Mount Mode

Hi All
I have configured Data Guard using Oracle 10g 10.2.0.4.0 (64 bits) on Windows 2008 Server (64 bits) Release 2 Enterprise.
Data guard configuration was OK as the message from "Enable Configuration DG1" was "SUCCESS" for both
Primary and Standby Database. I have also set both Databases and TNS to start Automatically whenever Windows Starts.
The Problem is as long as the Standby Server is running, there is No issue.
But when we Restarts the Backup Server, Physically Standby Database is Started and TNS is also Started,
but Archives are not received until I physically do the following steps so that it can received the Archives.
SQL> startup nomount;
SQL> alter database mount standby database;
SQL> alter database recover managed standby database disconnect from session;
Is there a way to start Physically Standby Database in Mount mode when windows started.

SECURITY PATCH ON STANDBY DATABASE AND PRIMARY DATABASE

I have a question on applying CPU on standby and primary database
I have a standby database on machine2 and primary on machine1
I applied a CPU patch on the Oracle Home of Standby database and
did not run the catcpu.sql as standbydatabase is in mount state.
Now i am going to apply the CPU patch on primary database.
What i need to confirm is that after i apply the patch on primary database oracle home
and run the cat cpu.sql on that do i have to do anything on the standby database
for instance rebuilding it or something or the change would be shipped to the standby
server automatically.
The purpose is to have the primary and standby database on the same patch level
in case of a failover
Please let me know asap

Any one has any idea on this. Any ideas would be appreciated

Creaton of Standby database and dataguard broker

Hi Experts,
I am using Linux with Oracle version 11gR2. We have planned to create a physical standby database and also configure dataguard broker for the standby database.
Also, I've read the documents that active dataguard is a feature on 11g. Is it not possible on 10g ?
Can someone please provide me the steps to create the standby database and configure the dataguard broker.

Hello;
A simple Data Broker setup would be :
On both Primary and Standby sites, change the initialization parameter in the spfile to enable the Data guard broker.
SQL> Alter system set dg_broker_start=True scope=both;
On the PRIMARY site, open the ‘cmd’ and start Command Line Interface (CLI) of the Dataguard Broker (DGMGRL).
/home/oracle:PRIMARY >dgmgrl
DGMGRL for Linux: Version 11.2.0.1.0 - 64bit Production
DGMGRL> connect sys/password@PRIMARY
Create broker configuration.
DGMGRL> create configuration ‘broker1’ as
primary database is 'PRIMARY'
connect identifier is primary;Configuration "?broker1?" created with primary database "PRIMARY"
DGMGRL>
(‘primary’ in Connect identifier is the service name through which the broker is connected to the PRIMARY database)
Add Standby Database to the above configuration.
DGMGRL> add database 'standby' as
connect identifier is 'STANDBY'
maintained as physical;
Database "standby" added
(‘to_standby’ in Connect identifier is the service name through which the broker is connected to the STANDBY database)
Now the configuration has been set up but it is still disabled. You can view the configuration by executing:
DGMGRL> show configuration
The next step is to ENABLE the configuration ‘broker1’.
DGMGRL> enable configuration;
Enabled.
Again view the configuration.
DGMGRL> show configuration
Configuration - ?broker1?
Protection Mode: MaxPerformance
Databases:
PRIMARY - Primary database
standby - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESSIn my humble opinion its a good idea to setup Data Guard without Broker and get the "feel" of it first.
Remember, once you setup Broker, you cannot use SQL to change your Data Guard setup.

Are Adobe promoting the alternatives to Database and Server Behaviours

The apparently disastrous depreciation of Database and Server Behaviours in Dreaweaver CC seem to have left a nasty taste in the mouth for many users. I am not a very experienced web developer, to the point where I cringe when describing myself as such, and I assume, possibly naively, that if Adobe have made them optional now, that there is an alternative; if not, the decision seems dimwitted in the extreme, and I did not expect that to be the case with a company who's software I have admired and found useful for so long.
So, assuming there is an alternative method to create dynamic data driven websites in Dreamweaver, can people please suggest what they are, and possibly point me towards the Adobe support and tutorials that encourage and explain their use. It must be in Adobe's interest to to get Dreamweaver's users to adopt the new technologies, and, at the moment, I cannot believe there is no adequate alternative.
I have seen many complaints about the depreciation of the support, but no one seems to be saying "don't use those, this is what you need to do the job". If anyone can do that for me, it would be greatly appreciated, and I imagine others would also benefit.
And if the alternatives are inadequate, then perhaps we could discuss how to get Adobe to repair a broken product.

As the web has evolved it makes sense that websites are no longer created by one person using one tool (DreamWeaver).
I agree with you there, depending at what level you are. A large design company will have specialists in all areas whilst a small one man set up will not. These small one-man band businesses usually attract low paying clients who will not have a budget to employ 'specialists' which is where DW server behaviours fitted in perfectly. Although it's benefited me enormously by learning how to manually connect and query databases I still think it was and is pretty lazy on the part of Adobe NOT to update the behaviours which were an important part of the program for many. 3rd party developers have produced extensions at a considerable cost, over and above what it costs to run DW. They quickly rolled out these extensions when it became clear Adobe had decided to upset many of its customers by not including any alternative in CC/CC 2014 - so don't tell me it would have taken many hours development and financial resources which Adobe just could not afford. That's bollocks. This is purely a decision by some wanker at top level in Adobe that is probably smoking crack and don't know their *** from their elbow, or what their customers really want.
Rob Hecker2 wrote:
It always seemed to me that by adding support for PHP/MySQL at all, Adobe was just going to frustrate people.
NO, the frustration is that Adobe introduce components and then doesn't develop them any further preferring to introduce a bag of dog poo into their programs like fluid grids instead of concentrating on what they do best.
Rob Hecker2 wrote:
PHP programmers do not use Dreamweaver for PHP Development. I recall a questionnaire on a website where the question was "What tools do you use for PHP development?" Dreamweaver was not even on the list of choices.
Serious php developers don't - you're right - but for those who don't program php/mysql on a daily or even weekly basis, but occasionally have the need for it, they do. Most websites can benefit from having a backend database these days and at a time when databases are main stream Adobe decide to ditch what was a premium attraction of the software, completely senseless decision. A few years ago when static sites were main stream Macromedia were ahead of the game an introduced the Server Behaviours. I guess the top brass in charge at the time (Macromedia) weren't smoking crack all day and instead listening to what their customers wanted.

Difference between physical standby database and Data Guard

Hi guys,
Today I attended one interview. They asked me a difference between the Oracle Physical Standby database and Oracle Dataguard?
Upto my knowledge Oracle Physical Standby Database is one type of Standby Database can be configured using Oracle Databaguard Feature.
Can you people calrify me on this.
Regards,
Vijayaraghavan K

hello,
yes you are right upto some extent...here is para form oracle doc
Oracle Data Guard is the most effective and comprehensive
data availability, data protection, and disaster recovery solution
for enterprise databases. It provides the management, monitoring,
and automation software infrastructure to create and maintain one
or more synchronized standby databases to protect data from failures,
disasters, errors, and corruptions.
Data Guard standby databases can be located at remote disaster
recovery sites thousands of miles away from the production data center,
or they may be located in the same city, same campus,
or even in the same building. If the production database
becomes unavailable because of a planned or an unplanned outage,
Data Guard can switch any standby database to the production role,
thus minimizing downtime and preventing any data loss.oracle data guard is maximum availiblity solution which maintain physical standby databases and in case of failure of production can switch production role to and standby database.

Logical Standby Database in NOARCHIVE Mode

Hi,
I have configured a Logical Standby Database for Reporting purposes. A Physical Standby Database is running for MAA. i.e. in case of Role Transition (switch/Failover) the Physical Stdby Db will get the role of the Primary.
The logical standby database is creating a lot of Archive Redologs files, nearly every minute. Redolog files are 50MB and there is no work done in db during the time. I'm NOT using Standby Redolog files.
Is there a need for logical standby database to be in NOARCHIVELOG mode? The Primary is definatley in ARCHIVELOG mode.
Thanks for any responses.
regards
Sahba

hi,
well there are two things to the above:-
1. there was an archive file nearly every minute:
this is due to a db recovery. for some reason, the db was in inconsistent state, after a sudden shutdownof the OS. I was on a test environment, on windows vista, unfortunately. unimportant ... a reboot solved it.
2. Logical standby db in NOARCHIVE MODE when setup for the purpose of Reporting.
As long as the MAA configured for the primary db, such as physical standby db, and a second, the logical standby db setup purely for the purpose of reporting, which then can run with NOARCHIVELOG mode, after converting the physical standby db to logical.
logical standby db uses Streams architecture, so this method brings cost, time and performance advantages to the customer.

Sahba

Logical Standby Database and XMLDB

I couldn't find a proper group to post this message and thought I would try here.
I want to set up a Logical Standby Database for our production database server 9.2.0.4.0 with XMLDB. I am having problem with some system tables that were created when I registered some XML schemas.
These tables are in the standby database but Oracle complains the object does not exist.
Any idea?

>
The "may be" is because I have tested flashback of a physical standby to before resetlogs, but not a logical standby.
>
A physical standby keeps the DBID of the primary - a logical standby does not. That is exactly the problem that restricts the reconversion into physical from logical, and you did not encounter that problem.
>
I haven't used "keep identity" but from what I read it relates to "convert to physical" not "flashback database".
>
Exactly. And that is what the OP wants to do: convert to physical (from logical).
You mentioned that this might be possible with flashback.
Problem: During the conversion from physical to logical, the DBID gets changed unless you specify (in 11g) KEEP IDENTITY. This would make it possible to reconvert into phyiscal from logical.
In short: If there is no solution for the changed DBID of the logical standby in order to flashback it into physical as you suggested, then it is not possible .
When I saw your first answer, I thought that you might have a solution in mind in order to solve that obvious problem. Sorry for having bothered you.
Kind regards

Standby Database (Archive Log Mode)

I'm going to be setting up a standby database.
I understand that the primary database must be in archive log mode.
Is there any reason for the standby database to be in archivelog mode?

Since your primary Db is in archive log mode, so will be your standby, when it is made primary.But. you can use STANDBY REDO LOGS from 9i version, where these Standby Redo Logs then store the information received from the Primary Database.
As per metalink:-
>
Standby Redo Logs are only supported for the Physical Standby Database in Oracle 9i and as well for Logical Standby Databases in 10g. Standby Redo Logs are only used if you have the LGWR activated for archival to the Remote Standby Database.If you have Standby Redo Logs, the RFS process will write into the Standby RedoLog as mentioned above and when a log switch occurs, the Archiver Process of the Standby Database will archive this Standby Redo Log to an Archived Redo Log, while the MRP process applies the information to the Standby Database. In a Failover situation, you will also have access to the information already written in the Standby Redo Logs, so the information will not be lost.

Creating standby database and replication of primary database in 9i

Hi,
We have a 9i database on Windows Server.Now recently we are planning to replicate the primary database to standby database once after creating the standby database.Can anyone guide me with the procedure or documentation with this . We were asked to do this without the data guard set-up. Please do help me regarding this ASAP.
Regards,

specifiying ASAP isnt a way to get people to help on a volunteer forum.
If you dont have dataguard You need to search for "manual standby apply".
lots and lots and lots of google hits for you but this is the official cookbook

Synchronizing local database and server database

Hi,
I am working on an application where users store information on their laptops in a local database. Once a day, synchronizing has to take place with the server database. The clients will send their mutated data to the server and the server will send its mutated data, e.g. changed item file.
The choice of database is Mysql for the laptop, and server resides on AS400, so DB2 is the platform.
I am wondering what techniques could be used to accomplish this. Should it be done by sql or via text files? Through a socket or something else?
Does anyone have an idea what the best approach is for this matter?
And if possible, some sample code would be very much appreciated.
Thanks in advance.

Hi,
There are numerous solutions to this. I have worked on a similar project a couple of years ago. The plan is as follows:
1. A java client is run on the laptop (user) which connects to the remote server on calls a procedure passing the localdata as the parameter.
2. the server parses the local data and updates itself and returns the updated data to the client.
The main considerations:
1. Connectivity: Connecting via internet to the server tunnelling through firewall or VPN ( I have no adequate knowledge on this).
2. The amount of data transfer. I was working on relatively less transactional data and hence the connection thru a dial up was not a problem.
3. The frequency of this operation. TO me it was once a day process, and hence I scheduled it during vee hours when the network was relatively free.
This is all my thoughts about the scenario. Any comments and suggestions are welcome.
Cheers,
Sekar

How Auto starting Physical Standby Database ( when Server Restart)

Dear All(s)
I have configure oracle (10.2.0) dataguard on production database, some time server restart due to power disconnectivity, i want to restard dataguard when server restart. i am using Server 2003 32bit. Guide me how i can run following commands when server restart.
SQL> connect/as sysdba
SQL> Startup mount;

Thanks in Advance

i want to run these command each time when server restart.Yes, I did understand that... but what's the problem ? can't you schedule a task when the server starts ?

OT: Bindings panel, Databases, and Server behaviors in Dreamweaver CC

Hi all,
There was a query on the Dreamweaver Facebook page about using server behaviors in Dreamweaver going forward. The product team replied to the post, and I am posting it on this forum for the benefit of users not on our Facebook page.
In Dreamweaver cc release server behaviors will be available as an extension. Once you install the extension server behaviors feature will be enabled and extensions dependent on it will work as before. In the CC release, you can find the extension at the location
* Vista/Windows 7: C:\Program Files (x86)\Adobe\Adobe Dreamweaver CC\Configuration\DisabledFeatures
* Mac OS X: /Applications/Adobe Dreamweaver CC/Configuration/DisabledFeatures
Additional documentation is available at
http://helpx.adobe.com/x-productkb/policy-pricing/dreamweaver-cc-server-extensions.html
Also, check out this video created by Silas http://www.youtube.com/watch?v=cB2vmNfcq7A
The Dreamweaver team has posted their view about the latest changes in Dreamweaver in their blog post http://blogs.adobe.com/dreamweaver/2013/06/a-look-at-the-modernized-dreamweaver-cc.html
Thanks,
Preran

I am sorry to say so, but your disappointing blog post just tells us two things:
You claim that you are listening to your users, but you have just proved you don’t. Despite the high volume of disappointment expressed through the comments to previous posts of this blog, through comments in Dreamweaver Help or through the Community Forum, you show no change of direction, nor any will to cater for the disrupted workflow that Dreamweaver CC is introducing. Instead, you are just producing blog posts that desperately try to prove us that you are “streamlining” and “modernizing” Dreamweaver. An extension that brings back half of the features is not a strong-enough signal that you have taken into account our needs. Extensions written by third parties which you claim are alternatives but are not resemble more leg-pulling than anything else. Will you reduce Dreamweaver’s price for the removal of killer features that were sold with the software before?
You do not seem to know how Dreamweaver users use the software or at least, to be fair, how a large number of users do. I thought the aim of software makers was to sell a tool that aids its clients in, and brings value to, their work.
As an extension writer, I can tell that the vast majority of my users are either DIY guys or professionals working on their own. Not big companies with teams of developers. The majority of those never have been Dreamweaver users and will never be, having different needs and ways of working.
As responses to your “streamlining” and “modernization” of Dreamweaver have shown, for a large number of users, the strength of Dreamweaver lies in its extensibility, of which server behaviors are the most advanced feature. I am not talking about the code they write, which we all agree has to be updated (and we have been waiting this for a number of releases, now…), I am talking about their very mechanism, which allow us to write our code and use Dreamweaver to speed up our job by helping us to write it again, faster, without errors, visually.
No other tool offers this possibility. Without server behaviors and database support, Dreamweaver is simply not worth its price…
Obviously, you are the ones with the real figures and only you can tell if it is a strategic decision or a big mistake. I was a bit surprised though by the number of voices that rose after the Dreamweaver CC release, so I tend to think that Mr. Adobe would not be that pleased by the loss of a good number of faithful clients. But then at least, be honest enough to tell us if you intend to drop a part of long-term users, and stop serving us your commercial soup…
Now, what will happen?
You still refuse to listen to the numerous voices who have called against your decision to remove useful features to us, and in this case, we will act accordingly: we are big enough, we do not need your blatant propaganda even by the product manager himself to decide whether Dreamweaver CC will still be worth its high price into our workflow, if the new features will outweigh the loss of server behaviors and database support. If not, of course, we will not upgrade just because you are marketing the supposedly wonderful new features, and we will turn to other tools, with features that will help us improve our workflow in other ways. And goodbye Adobe, we do not trust you anymore… It is as simple as that.
You show us you really are listening to your customers and you bring back updated server behaviors and database support. In this case, we will know that we can trust Adobe again, that you do listen to us, and will applaud with both hands.
And, more important to you, we will have a valid reason to upgrade and we will. Come on guys, our productivity is at stake, but your jobs may be in the line too…
