Use dedicated server for data guard?

Hi All,
I've heard from someone that it is possible to separate data guard from the database and put it to a server, such that the data guard server will be dedicated to shipping log to standby site db etc. I don't know if such architecture would work. Could anyone please clarify it? Thanks in advance.

An Introduction to Data Guard from Oracle Doc's is here:

Separate listener for Data Guard

I am setting up a best practice about using a dedicated listener for Data Guard. The idea is to maintain full functionality of Data Guard while application team is requesting to bring down listener service (according to business requirement). Need your opinion on these:
1. I understand that there may be a very little chance when listener is required by Data Guard, but I find it no harm to do this. Do you agree with me?
2. In RAC environment, we can only have 1 VIP to be used in listener.ora. I am thinking of using same IP but different port numbers for different listener. Any better idea than this?
Many thanks

It is never a bad practice to use separate listeners at the primary and at the Standby for Data Guard's use. A listener at the standby is required by Data Guard to make a connection to that standby. A listener at the Primary is required for Data Guard to make a reverse connection from the Standby to the Primary for some kinds of Gap resolution (missing log file the the Primary thinks it already sent or a corrupted log file etc). And of course, when you switch roles.
To answer the second question could you please tell me what version of Oracle you are using and if you plan on using the Data Guard Broker or not?
Thanks.

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,

Can I use Leopard Server for a few things without a static IP/DNS mapping?

Caveat: I'm pretty capable at setting up and running macs, but not a crack server admin or anything like that. I don't write code and my eyes start to glaze over when you start talking about Kerbos and the like...
Question: I'd like to use Leopard server for a few things on my local network - with some vpn access to the same services:
- iCal server (the most important feature) for 3 users
- File server services for Time Machine (yes, base Leopard can do this)
- vpn access into the iCal server for one user
Do I have to go through the headache of switching over from a dynamic IP to a static IP, setting up DNS mapping, etc? Or is there a simpler way?
Any help appreciated. Thanks

Using number datatype for date column

Hi
Is there a side effect for using "number" datatype for "date" column?
If so, what is the disadvantage?
Many thanks

Oracle provides date arithmetic and a number of functions for manipulating DATEs. None of them work with numbers.
For example,
SELECT    TRUNC (order_date, 'MONTH')     AS order_month
,       AVG (ship_date - order_date)     AS avg_delay
FROM       orders
GROUP BY TRUNC (order_date, 'MONTH')
;order_month involves a DATE function; it's pretty easy to find the month that conatins order_date.
avg_delay involves date arithmetic. It's extrememly easy to find how much the time passed between order_date and ship_date.
Depending on how you code dates as numbers, doing either one of the above may be just as easy, but doing the other will be very difficult. You'll waste a lot of effort converting the NUMBERs to real DATEs whenever you need to manipulate them.
Validation can be very difficult for NUMBERs, also.
Watch this forum. It's a rare day when there's not some question about how to get around a problem caused by storing dates in a NUMBER (or VARCHAR2) column. Don't add to that. Always use DATE columns for dates.

"do not use proxy server for local (intranet) addresses" IEM setting

Hi, i would like to find out where can i find the following setting in GPO which used be found in IEM.
"do not use proxy server for local (intranet) addresses" Enabled/Disabled
as currently im setting the IE proxy exception list via GPP, i don't see that option.

Hi,
As you notice that when we use GPP Internet Setting item to configure bypass proxy servers, there is no "do not use proxy server for local (intranet) addresses" option in GPP Internet
Setting item. However, as suggested by zanderol24’s reply, we can use bypass proxy server for local addresses option under
Proxy server to achieve the same function.
Best Regards,

Sorry but that makes no sense in English. Only your mobile phone company (i.e. "carrier") can enable the Personal Hotspot feature.

Use MacMini server for windows apps and save for windows files ?

My question : Office equiped mixed computers , aslo Windows and Mac,
Could we use MacMini server for both machines, working by windows apps and / or to save and work with windows files on MacMini server and with Mac as well?
We woud use it for normal office work and get it by internet from other places as well
windows apps: merchandising, invoice, word, excel, pictures editing, Outlook Express + the Mac apps
thnx ,
MACIren

In general what you can do is: in OS X, use Windows in virtualization (aka emulation), as a "virtual machine" with VMWare Fusion, Parallels, or Oracle VM Virtual box.
That way you have both operating system open side by side without having to reboot into one or the other operating system.
Not sure whether you need a Mac Mini Server per se to do that, I do that with my MacBook Pro for instance. But the server would help since it has a quad-core CPU (more cores that you can dedicate to the virtual macine), and you can put the virtual machine on the second harddrive for better disk access performance. Was there some particular reason you were thinking of the Mini Server -- do you want to use server side Windows apps?
Again I have that setup on my MacBook Pro using VMWare Fusion with an XP virtual machine. In the Windows, I only use Office 2003 and some company apps that are Windows only. With Fusion (and I'm sure the other apps can do it as well) you can set a "shared" folder so both Windows and Lion will see the contents of it for reading and writing. I believe with Fusion you can also do your entire Home directory, but I prefer to limit it to a single shared "work" folder.

Question on db_unique_name in init.ora for Data Guard

I need to set up only one physical standby on a different box (at a different location) for the primary db in production.
OS: Sun Sparc Solaris 10
Oracle: 10.2.0.3
Can I use the same db_unique_name in init.ora for both primary and standby DBs?
What are the minimal parameters required by Data Guard I have to specify in the init.ora in my case?
Could anyone please post an example of init.ora for both primary and standby DBs?
Thanks very much in advance.

Oracle: 10g R2
O/S: Windows
Primary database ken10g
standby database: ken10gbk
Following is the content of my current listener files on both of servers:
Primary server:
# listener.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =

Hi Ken,
You need to configure this on both primary and standby, I would have kept different listener name on primary and standby. Also if you are going to use dataguard broker you would need to set GLOBAL_DBNAME in your listener.ora file
I have give a sample entry for tnsnames.ora and listener.ora
TNSNAMES.ORA on primary
STNDBY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = node2-prv)(PORT = 10521))
(CONNECT_DATA =
(SERVICE_NAME = STNDBY)
PRIM =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1-prv)(PORT = 10521)))
PRIMARY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1-prv)(PORT = 10521))
(CONNECT_DATA =
(SERVICE_NAME = PRIMARY)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
Copy the same file to the standby server and adjust it based on the listener.ora file. Also update the listener.ora file so that it listen the SIDs mentioned in the tnsnames.ora file.
Listener.ora
LISTENER_STBY =
(DESCRIPTION_LIST =

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.

Using OEM to monitor Data Guard database

Can someone please send me the link or docs of how to use OEM monitoring data guard? In specific, I would like to use OEM to monitor and be sure logs are applying to stand by site.
Any ideas?

Hello ,
I will extend the document on the Fast Failover feature one of these days.
What you need to do is:
For using Fast Failover, you need to configure the Data Guard observer process.
The configuration of this process can be done by selecting the Fast-Start Failover Disabled link on the Data Guard page of the database (Primary or Standby).
You will be automatically redirected to the Fast-Start Failover: Configure Page.
From this page you can do the configuration of the DG observer process, that then will enable you to activate the Fast Failover feature.

Use dedicated server for data guard?
