Implementing dataguard on same machine

Hi
I am trying to implement Dataguard to create physical stand by using the primary database on the same system in windows platform. My questions are:
1. Is possible to implement on the same machine where the primary database resides. If so do i need to install a seperate oracle software i mean oracle home path on it for the standby. This question was asked because in one of my posting regarding the dataguard, one guy has specified that for implementing dataguard on same machine..i should have different Oracle_ Home paths. Is that true.
2. If not is it possible to set the path like this in same machine and using same oracle_home path:
Primary Dtabase --> oracle\product\10.2.0.4\db_1
Physical Standby --> oracle\product\10.2.0.4\standby

What is your Oracle version?

Yes that is possible.But there you have to use db_unique_name initialization parameter.Provide this params value different between primary and standby database.And do not need create additionally ORACLE_HOMEs.
2. If not is it possible to set the path like this in same machine and using same oracle_home path:
Primary Dtabase --> oracle\product\10.2.0.4\db_1
Physical Standby --> oracle\product\10.2.0.4\standbyDo not need additionally ORACLE_HOME.Just create additionally directories and continue.

Creating physical standby database on same machine with dataguard

hi every one
i m new in oracle databases,
i read documentation to create physical standby databases,
now i install virtual machine (vmware) on my system,
i install windows xp on this vm and oracle 9i
now i want to create standby database on the same machine in some other drive configured with datagurd
virtual machine
OS windows xp
database oracle 9i
plz reply me how i do this
explain clearly step by step.
plz reply me in detail

When you need to have the standby database on the same server as the master, use lock_name_space in the init.ora.
This parameter permits this to occur without having to worry about changing the db_name.

Tomcat : Hlow to run more than 1 instance of tomcat server on same machine?

Hi,
How to run more than 1 instance of tomcat server on the same machine.
I use tomcat 5.5. ,updated port number for second instance and tried to run,it takes the same old port number .No batch file available with this version to update the home directory to second instance to run the second server..
How to work on clustering and load balancing on tomcat server?

If are only getting your site hosted, then, normally, the host would handle clustering (to your sepcifications, of course, but it is normally the hosts responsibility).
If i need to implement clustering and load balancing for tomcat server then do we need to go for 2 different servers for production environment?
Yes, you would need two, or more, servers.
Also please guide me on how to implement clustering and load balancing for tomcat server by running 2 instances on 2 different machine? I'm a newbie to it..
It should have no (or at least minimal) impact on the code (as long as you are using beans, sessions, and the other components properly). It is handled by the web container (by the tomcat in this case). The tomcat documentation should show how to set it up (if it supports it all, I don't know, we don't have Tomcat at work, and at home I use only a single).

Configuration of the Physical & Logical standby servers on the same machine

I've encoutered a problem to connect to one of the standby servers .
I created a DataGuard in 10.2. Primary on 1 machine, 1 physical standby and 1 logical standby on another machine (both phy and logical in same machine)
I first created a primary then a physical standby. I've got no problem at all.
But when I created a logical standby server on the same machine with the physical then I could not connect to both phy and logical . I can connect to either one of them.
According to DataGuard setup, the db_name must be the same in primary and all standby servers. This is fine when each of the primary or the standby installed in a separate machine.
The db_name of the physical = rolex
The db_name of the logical = rolex
When we have more than one instance in the same machine, we just set the ORACLE_SID = db_name ( or instance), then connect to it.
If I connect to the physical, then I try to connect to the logical, it goes to the physical or vice versus.
Does anyone have the solution ?
QN

DB_UNIQUE_NAME parameter will be the seperator.
give DB_UNIQUE_NAME parameters different names and set ORACLE_SID with DB_UNIQUE_NAME name you gave
DB_NAME is the primary instances database name DB_UNIQUE_NAME is given for standby instances database name

Encountering ORA-01152 when implementing DataGuard

Working of a 2-node cluster hosting 11.1.0.7 on a Linux RH4 platform, and attempting to implement DataGuard on a single node with same OS and same DB version, and followed document http://www.oracle.com/technology/deploy/availability/pdf/dataguard11g_rac_maa.pdf
The "duplicate target " command works successfully, and having recreated the sp file on the standby node, when I attempt to startup the standby database I get the following error.
SQL> startup
ORACLE instance started.
Total System Global Area 534462464 bytes

ORA-01110: data file 1: '+DATA/abcdg/datafile/system.258.697912407'
I have re-tried several times without success - any ideas anybody?

I've skimmed the PDF and I think what has happened is that you may have slightly diverged from the sequence shown by issuing "startup" instead of "startup mount", the difference being that "startup" tries to open the standby database in read only mode, which is when ORA-01152 is thrown.
I'm assuming here that the rman duplicate operation does not include a recovery phase, if that is true then the restored datafiles will need recovering to a consistent state before the database can be opened in read-only mode.
In short you probably just need to issue:
recover managed standby database disconnect;and let managed recovery run the archive logs in. Once it is consistent then subsequent "startup" commands should work without error.
If you don't actually want it open read-only then you can just leave it in a mount state and running managed recovery.

Can Veristand 2009 and Veristand 2010 be installed on the same machine?

I have VS2009 running on my machine. I would like to install VS2010 as an eval to start porting an implementation over to VS2010 before I pull the plug on VS2009. Can these bothe be installed and functional side-by-side on the same machine? Are there any caveats to bouncing back and forth between the two? I already have the prereqs listed on the VS2010 eval page (NI-DAQmx 9.1.5, NI-RIO 3.5 and NI-XNET 1.1).
Solved!
Go to Solution.

Hi,
I have VS2009 and VS2010 installed in my Windows XP and I can work with them without any problem.
I also tried to port my LV2009 programs to LV2010 but I got problems with VS2009 Off-line API VIs because LV2010 can not convert them. According to the error message, NI delivered the API VIs protected (without diagram).
I believe that you could not have VS2009 and 2010 in the same RT target.

Then you haven't followed the method correctly. That error is
addressed specifcally on that site, as that error is the main
reason for the site. Did you read the note about the "known
bug" because of the one port that is not included in the
sample file?
If you had tried the first method (set up a second IP and
started both servers with the command line option providing
an IP) there is no way this error could happen.
If you followed the second method, and specified a different
port for every port listed (including the one that is not in the
sample file per default) then there is, once again, no way that
this error could happen.
The error happens on the second server because it is trying
to bind the same port, using the same address, as the first
server, which is impossible if you fully implement one of the
two methods described there.

I want to run an NI GPIB card and a Keithly GPIB in the same machine.

I want to run a NI GPIB and a Keithly in the same machine for software development. Our labs use both types of card. Another employee tried to make it happen, but failed. I would like to use 1 machine due to software licensing issues.

Hi,
There shouldn't be any interaction between the two GPIB drivers. The NI interfaces will use NI-488.2, wil the Keithley interfaces will use their low-level device driver. Each driver will manage the their own hardware.
In LabVIEW, you will use the NI-488.2 Vis to communicate with the NI interface. The Keithley driver has to install their own driver interface VIs.
The only problem is you want to use VISA for both interfaces. I don't know if there is a Keithley implementation of VISA, but there can nly be one installed in the system. The NI_VISA driver will allow you to control the NI interface, but not the Keithley interface. You can still use the Keithley interface using the low-level driver.
Finally, here is a knowledge base I found that has
some information that may be useful to you Using a Keithley PC488 GPIB Interface with LabVIEW
Hope this helps.

Test & Dev on Same Machine

Hi,
I want to install test & dev on the same machine
what i know is i have to assign different port numbers to them.
But i want to access them with diffrenet url addresses
how i can install with same host or different host
plz clarify
one more thing, how i can synchronize test & dev instance on the same machine
i mean combine them
but access them separately
sorry for my terminology
Thanks in advance....

You can install multiple instances on the same server. The URL for each will be slightly different - each URL will have a different port number (but the same hostname). Another option is to use virtual hostnames - this is an advanced feature described in these MOS Docs

Does it support install OEM12c with OEM12c ops center into same machine?

Hi,
I'm not familiar for OEM and OPS center.
- Does it support install OEM12c and OEM12c ops center into same machine?
- Would you please share any hardware / OS in OEM12c and OEM12c ops center?
Thanks.

Holger,
Thanks for the reply, that was useful.
I posted this message in service markeplace, and got a reply from SAP, and they do not have out of box solution. Since the project is on aggressive schedule, may be this issue, which involves lot of devlopment needs to tackle in next proect cycle.
Qustion regarding the Apache was also resolved. Reply from SAP is posted below.
Thanks,

HI Mr Durga,
Can a user say "abc" can have different content displayed while he
logins from Internet or intranet.
This feature is not provided with the standard Delivered NWO4 suite.
I would ask you to take this query in the sdn forum,as these type of
questions are answered by SAP consulting guys.
As far as multitenant EP is concerned,
Based on ramp-up experience and customer feedback, SAP has decided to

Interprocess Communication on same machine (Help needed)

Hello everyone, I have a question that I thought you guys could help. Actually I have multiple processes running on a same machine and I want to put messages from one process to the queue of other process what is the best way to achieve this functionality in Java?
Currently I'm working on C++(linux). I have a webservice and some TCP listener processes running on the same machine, and there is another process (i call it processing engine) running one the same machine. So everytime I receive the message from webservice or from TCP socket, I write those messages to the Queue of Processing Engine, and after processing that message my processing engine writes the reply to the queue of webservice/TCP (from wherever it received the message).
I want to achive the same functionality in java. My messages are simple literals/string and I'll write all my processes (webservice/tcp/proc. engine etc) in java aswel.
Secondly I want to process the messages according to FIFO.
Your help will be appreciated.
Thank you.

What we are trying to accomplish is implement a transaction processing system...
There will several processes working independently, but these processes will be sending messages to one another.. for example
- a TCP process will read the message and translate it into our internal message format and send that formatted message to Processing engine..
- TCP process will then wait for other message from the network..
- Processing Engine will do its job and reply back to TCP process...
We cannot incorporate all the business logic in one process .. since its too big...
Why not? The first server should not involve that much processing. So only the second is the problem. And that is one server.
And what is the actual performance metrics for a single server?
For comparisons I usually use max 2000 txns a second. If you have a server that handles 100 txns a second then you need between 25-40 servers depending on the target box load and back up servers. That really isn't a lot of servers if you really are doing 2000 txns a second (and getting a reasonable per txn fee.)
And I speak from some experience since I have been working on txn processing systems for years.
But I can see the allure of thinking that the front end and back end make more sense. One real advantage is adding another front end (different protocol) without touching the current systems.
Communications options that do work that way would normally be
- messages via sockets
- message queues.
Remember JMS is an API not a solution so you for the second above you need to investigate solutions.
I consider message queues more complex than sockets (message queues of course use sockets and provide more functionality so that is probably a reasonable view.) There have however been some impressive processing speeds reported for them. And getting that same throughput using sockets takes some work.
For either solution spend some time building some non-trivial test setups to gauge real speed paying attention to what you expect your real production needs to be. Experience speaking there since what they claim and what one can actually do for a particular situation can vary.
Keep in mind that a two server solution where you anticipate that the second server might be doing more work might suggest that you need to consider a cluster of second servers servicing the front end server. Either solution requires thought about that before implemetation proceeds.

Configuring Data Guard on 2 different instance in same machine

Hi All,
I am new to the Data Guard concept. I am using Oracle 10g (Release 10.2.0.1.0) in Windows 7 environment . I have created 2 database instance its running fine.
For testing purpose, Is it possible to implement Data Guard concept between 2 instance in the same machine? whether it will impact any problem?
Thanks & Regards
Sami.

You would use the same one. That is, you would not have a separate tnsnames.ora and listener.ora.
What I was trying to say is you still need to add the SID_LIST_LISTENER lines that Data Guard uses
Example
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(PROGRAM = extproc)
(SID_DESC =
(global_dbname = PRIMARY_DGMGRL.uservices.umn.edu)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(sid_name = PRIMARY)
TNS Example
STANDBY =
(DESCRIPTION =
(SDU=32767)
(SEND_BUF_SIZE=2092500)
(RECV_BUF_SIZE=2092500)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = HOSTNAME)(PORT = 1521))

Problem with 2 physical standbys on same machine

Hi,
I've set up the Dataguard with one primary on machine A and 2 physical standbys on the same machine B.
Note: the Dataguard worked fine with one primary and one phy standby on the separate machines.
The problem I have is the Redo Logs can only applied to either one of the phy stdbys.
Which one started 1st, then that phy stdby can apply the Redo Log.
The redo logs have been transferred to both phy stdbys successfully but ONLY one phy stdby can apply the Redo Logs.
Anyone got this experience, pls point out. Thanks.

Thanks a lot for asking me questions. Thus I understand my problem.
I checked the locations of datafiles of both phy stdbys, I saw they use the same datafiles.
Because when I created the phy standby, I shutdown the pri, copy a COLD backup of the pri to the stdby, then startup mount db. This is not right. The directories of the datafiles are not the same.
I'm not clear about how to create a phy stdby if their directories of the datafiles are different.
Thanks.
