Best Practice for monitoring database targets configured for Data Guard

We are in the process of migrating our DB targets to 12c Cloud Control.
In our current 10g environment the Primary Targets are monitored and administered by OEM GC A, and the Standby Targets are monitored by OEM GC B. Originally, I believe this was because of proximity and network speed, and over time it evolved to a Primary/Standby separation. One of the greatest challenges in this configuration is keeping OEM jobs in sync on both sides (in case of switchover/failover).
For our new OEM CC environment we are setting up CC A and CC B. However, I would like to determine if it would be smarter to monitor all DB targets (Primary and Standby) from the same CC console. In other words, monitor and administer DB Primary and Standby from the same OEM CC Console. I am trying to determine the best practice. I am not sure if administering a swichover from Cloud Control from Primary to Standby requires that both targets are monitored in the same environment or not.
I am interested in feedback. I am also interested in finding good reference materials (I have been looking at Oracle documentation and other documents online). Thanks for your input and thoughts. I am deliberately trying to keep this as concise as possible.

OMS is a tool it is not need to monitor your primary and standby what is what I meant by the comment.
The reason you need the same OMS to monitor both the primary and the standby is in the Data Guard administration screen it will show both targets. You also will have the option of doing switch-overs and fail-overs as well as convert the primary or standby. One of the options is also to move all the jobs that are scheduled with primary over to the standby during a switch-over or fail-over.
There is no document that states that you need to have all targets on one OMS but that is the best method for the reason of having OMS. OMS is a tool to have all targets in a central repository. If you start have different OMS server and OMS repository you will need to log into separate OMS to administrator the targets.

Database is configured for Data Guard

I am run a UTF8 conversion on a development database that has been cloned from Data Guard. There is a warning in Migration Status: "Database is configured for Data Guard" What is the DMU looking at to determine this? The database is open in read-write mode and it behaving like a primary database (I run the DMU scan and run updates to fix invalid representations). I would like to know what settings I need to update.
Is this preventing me from converting tables using CTAS? When I try to select this for all tables I get the message, "The DMU does not support the conversion method "Copy data using CREATE TABLE AS SELECT" for tables that are involved in an Oracle Streams process, like capture or apply. Use another available conversion method for the table"
Thanks,
Ben

The DMU checks if the parameter DG_BROKER_START is set to true.
The problem with CTAS is independent from Data Guard. The DMU checks for tables that:
- are source of asynchronous Streams capture, or
- have update conflict handlers, or
- have DML handlers, or
- have conflict resolution parameters
The above tables are considered configured for Oracle Streams and are not supported by CTAS conversion method. This is because the CTAS method creates a converted copy of the table and drops the original. The DMU is not capable of moving the Streams configuration information from the old table to the new one.
Thanks,

Best practice to monitor 10gR3 OSB performance using JMX API?

Hi guys,
I need some advice on the best practice to monitor 10gR3 OSB performance using JMX API.
Jus to show I have done my home work, I managed to get the JMX sample code from
http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/jmx_monitoring/example.html#wp1109828
working.
The following is the list of options I am think about:
* Set up: I have a cluster of one 1 admin server with 2 managed servers, which managed server runs an instance of OSB
* What I try to achieve:
- use JMX API to collect OSB stats data periodically as in sample code above then save data as a record to a
     database table
Options/ideas:
1. Simplest approach: Run the modified version of JMX sample on the Admin Server to save stats data to database
regularly. I can't see problems with this one ...
2. Use WLI to schedule the Task of collecting stats data regularly. May be overkill if option 1 above is good for production
3. Deploy a simple web app on Admin Server, say a simple servlet that displays a simple page to start/stop and configure
data collection interval for the timer
What approach would you experts recommend?
BTW, the caveats os using JMX in http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/jmx_monitoring/concepts.html#wp1095673
says
     Oracle strongly discourages using this API in a concurrent manner with more than one thread or process. This is because a reset performed in
     one thread or process is not visible to another threads or processes. This caveat also applies to resets performed from the Monitoring Dashboard of
     the Oracle Service Bus Console, as such resets are not visible to this API.
Under what scenario would I be breaking this rule? I am a little worried about its statement
     discourages using this API in a concurrent manner with more than one thread or process
Thanks in advance,
Sam

Hi Manoj,
Thanks for getting back. I am afraid configuring aggregation interval from Dashboard doesn't solve problem as I need to collect stats data of endpoint URI or in hourly or daily basis, then output to CSV files so line graphs can be drawn for chosen applications.
Just for those who may be interested. It's not possible to use SQL to query database tables to extract OSB stats for a specified time period, say 9am - 5pm. I raised a support case already and the response I got back is 'No'.
That means using JMX API will be the way to go :)
Has anyone actually done this kind of OSB stats report and care to give some pointers?
I am thinking of using 7 or 1 days as the aggregation interval set in Dashboard of OSB admin console then collects stats data using JMX(as described in previous link) hourly using WebLogic Server JMX Timer Service as described in
http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jmxinst/timer.html instead of Java's Timer class.
Not sure if this is the best practice.
Thanks,
Regards,
Sam

Best practice on monitoring Endeca health / defining outage

(This is a double post from the Endeca Experience Management forum)
I am looking for best practice on how to define Endeca service outage and monitor the health of the system. I understand this depends on your user requirements and it may vary from customer to customer. Specifically what criteria do you use to notify your engineer there is a problem? We have our load balancers pinging dgraphs on an interval. However the ping operation is not sufficient in our use case. We are also experimenting running a "low cost" query to the dgraphs on an interval and using some query latency thresholds to determine outage. I want to hear from people on the field running large commercial web site about your best practice of monitoring/notifying health of the system.
Thanks.

The performance metric should help to analyse the query and metrics for fine tuning.
Here are few best practices:
1. Reduce the number of components per page
2. Avoid complex LQL queries
3. Keep the LQL threshold small
4. Display the minimum number of columns needed

What is "best practice" to set up and configure a Mac Mini server with dual 1 TB drives, using RAID 1?

I have been handed a new, out of the box, Mac Mini server. Has two 1 TB drives in it. Contractor suggested RAID 1 for the set up. I have done some research
and found out that in creating the software RAID, this takes away the recovery partition, so I have been reading up on how to create a recovery "disk" using a thumb drive. this part of the operation I am comfortable with, but there are other issues/concerns that I have.
Basically, what is the "best practice" to setup the Mini, configure the RAID and then start the server. I am assuming the steps would be something like this:
1) start up the Mini and run through the normal Maverick setup/config - keep it plain and vanilla
2) grab a copy of the Server app and store it offline in a safe place
3) perform the RAID configuration / reinstall of OS X Maverick using the recovery tools
4) copy down and start the server app
This might be considered a very simplified version of this article (http://support.apple.com/kb/HT4886 - Mac mini server (Late 2012 and Mid 2011): How to install OS X Server on a software RAID volume), with the biggest difference being I grab a copy of the Server App off of the mini before I reinstall, since I did not purchase it from the App store, but rather it came with the mini.
Is there a best practice / how-to tutorial somewhere that I can follow/learn from? Am I on the right track or headed for a train wreck?
thanks in advance

I think this article will answer your question. Hope this helps: http://wisebyte.blogspot.com/2014/01/best-configuration-for-mac-mini-server.html

Is there an app for monitoring CELLPHONE usage? (Not data, calls, SMS, etc.)

Hey! Is there an app for monitoring CELLPHONE usage? (Not data, calls, SMS, etc.). I know there's for data, but I wanna know if there's one that keeps track of calls, SMS, etc.
Thanks!

Unless O2 has an app available via the iTunes app store that provides for this as AT&T does for the iPhone sold in the U.S., I don't believe so.
The iPhone includes a usage indicator for Call Time and Cellular Network Data usage, which can be reset on a monthly basis based on your billing cycle, but there is no usage indicator for the number of messages sent or received.

Init SID .ora during configuration of Data Guard - advice required

Hi All,
I am looking to implement data guard across 2 RAC clusters. One cluster will be primary and the other is for Disaster Recovery.
I have already set up the two 11g R 2 RAC clusters on RHEL 5 and now need some pointers to good docs for data guard install.
Can some one direct me to good step by step info for configuring data guard between to RAC clusters - detailed explanations of each step would be useful too, in particular around the init.ora file configuration changes between the primary and DR sites
Much appreciated

Database issues after starting data guard

Hi. We run OEM12c in Linux. All is working well and we monitor several targets and DBs.
In our QA db server, sun solaris 11 running oracle 10g, we started to test data guard configuration for several instances we are running there. our standy server is called STDBY. All works fine, but now we have a problem managing some aspects of data guard with OEM12c.
First problem is that the instances appear as SID_IPaddress of server, as opposed as DB_UNIQUENAME.DB_DOMAIN. curiously enough, the std by copy, appears correctly (SID_sbyp.db_domain)... This is very puzzling...
Second problem is when we try to access the Data Guard performance pane, it fails showing (both in primary and secondary DBs)
Data Guard Internal Error : See the OMS log for details.
No clue where to look for this problem.
All other functions, TOP, performance home, etc... look fine.

Hi ,
Regarding "Data Guard Internal Error : See the OMS log for details"
Follow the below steps
On the Data Guard Page run the 'Verify Configuration'-Option twice. The first Execution will show an Output like
Initializing
Connected to instance test.oracle.com:mydb
Starting alert log monitor...
Updating Data Guard link on database homepage...
WARNING: Broker name (mytest) and target name (mydb) do not match.
WARNING: The broker name will be renamed to match the target name.
Skipping verification of fast-start failover static services check.
Data Protection Settings:
Protection mode : Maximum Performance
Redo Transport Mode settings:
pnjpcep1: ASYNC
cnjpcep1: ASYNC
Checking standby redo log files.....not checked due to broker name mismatch. Run verify again.
Checking Data Guard status
mydb : Normal
my11g : Normal
Tthe second Execution does not show this Warning any more, ie. it got fixed during the first Execution. Now it's possible to access the Data Guard Performance Page without Errors and you can see the Statistics.

Best practice with respect to wcf configuration files for SSIS

So after reading a lot of posts and blogs on how to configure SSIS to read from configuration files , I am still not clear and would like any expert to provide a definitive stance. In my case the WCF service consumption is wrapped into a separate assembly.
I am referencing the assembly in an embedded C# script within my SSIS package.
When I make the helper class call to the webservice , I get the endpoint not found WCF exception.
Keep in mind I am running this from VS 2012 IDE and did the following to make sure the WCF call works:
1. Googled and found that you need to have config entries in DtsDebugHost.exe.config file. But it still did not work
2. Had the same entries in the associated app.config file for C# script but it still did not work.
It seems like SSIS is very fragile w.r.t consuming WCF entires in a config file. Is the best practice to just have the end point created in code and externalize the end point as a SSIS variable / xml file or is there really a way to get these config files working.
Attached is the wcf snippet of my config file.
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="ITransactionProcessor">
<security mode="TransportWithMessageCredential" />
</binding>
</basicHttpBinding>
</bindings>
<client>
<endpoint address="https://ics2wstest.ic3.com/commerce/1.x/transactionProcessor" binding="basicHttpBinding" bindingConfiguration="ITransactionProcessor" contract="CyberSource.ITransactionProcessor" name="portXML" />
</client>
</system.serviceModel>
SM

I have the code working without use of config files. I am just disappointed that it is not working using the configuration files. That was one of the primary intents of my code re-factoring.
Katherine
Xiong , If you are proposing this as an answer then does this imply that Microsoft's stance is not to use configuration files with SSIS?? Please answer.

Meanwhile, to reduce the risks and time consumed during the completion of migration process, you can have a look at this proficient application(http://www.exchangemigrationtool.com/) that would also be
a good approach for 1500 users. It will help you to ensure the data security during the migration between exchange 2007 and 2013.

Best practice to implement different Xcelsius dashboard for different users

I'm implementing an Xcelsius dashboard that requires to show each individual user with different content (e.g. When a user logins in, the dashboard shows her name and job title, her performance and her subordinate's performance). I'm just wondering what's the best practice to implement scenario like this? Thanks.

Hi Thomas
What you are looking at is "Row Level Security" within BusinessObjects and the options you have are determined by what type of data you are reporting off of (relational data, OLAP data, BW data, etc.)
For instance, if you are using relational data with a Universe you could setup a database table with the BusinessObjects username to correspond with their e-mail address or other unique identifier. From there, you could add security to your universe using the @variable('BOUSER')
That way, any objects created off of the universe (whether it is a Crystal Report, Web Intelligence, BI Web Service, QaaWS, LiveOffice, etc.) will filter the data based on this security model. So any Xcelsius dashboard based on this underlying data will also be filtered.
And that is just one of the options you have, depending on your data source.

Best practice to Deployment Oracle WebCenter Suite for enterpsie

I have a lead with enterprise client; and we need to proposed to this client best practice to deploy high availability on cluster environment contains the following components:
- oracle web center content: it will used for WebCenter portal (spaces) repository for x-trantent portal as well as it will used to build internet website using WCM
- oracle WebCenter portal; to build x-intranet portal
- oracle access manager for single sign on authentication
- oracle web tier for HTTP server and web cache.
i reviewed the enterprise deployment "http://docs.oracle.com/cd/E23943_01/core.1111/e12037/intro.htm" and contains rich information on the configuration.
However; my question is could you provide us a best practice to deploy above components on a high availability cluster environment "on a Linux environment prefared" to support and tested around 20k users? By the way client already had oracle exadata 11g server and it will used for this deployment.

Is OEM database control configured for the DBs?

Hi
I have multiple oracle (10gR2) databases running on a linux (5.8) server. How can I check that for which of the databases has the OEM Database Control been configured and on what port is it listening?
Best regards

Thank you everyone!
Here is what I see (I have changed the DB names):

And these "dots" just continue to appear and it is running for 15+ minutes now.
Please advise how to check what is happening.

Any best practice/suggestion on giving Id's for UI Component

Hi,
I came to know that for better performance, id's on naming containers shall be less than 7 characters in length.
What about UI Components other than container components?
Is there any best practice available for giving Id's for UI Components and its length?
Do we face any issue if we give ids with more than 7 characters (just to make the id meaningful one)?
Thanks in Advance
Raguraman

a quotation from
Oracle® Fusion Middleware Performance and Tuning Guide book
11g Release 1 (11.1.1)
E10108-02
>
The "id" attribute should not be longer than 7 characters in length. This is
particularly important for naming containers. A long id can impact
performance as the amount of HTML that must be sent down to the
client is impacted by the length of the ids.
