Two clusterware homes on one machine?

I want to install a test environment for 11g RAC.
I have a test environment with 10g RAC, and to avoid requesting new machines I want to install 11g on same two nodes.
I know that I can have 10g and 11g databases on top of 11g clusterware, but I want to do something a bit different.
I'd like to have 11g DB on 11g clusterware and 10g db on 10g clusterware, by installing two clusterwares in two different clusterware homes on the same machine.
Any reason this will not work?

Well clusterware exists on disk as a set of files and entries in confguration files etc. you'd have to rename - /etc/oracle and also poke about inside /etc/inittab amongst other changes.
It would be easier to base your system on Oracle Clusterware 11g

Two ASM instance on one machine

Can we have two ASM instance on one machine ? My Manager is saying he is positive and I don't have anything to show him that we can not do that. Is there any link, document anything available for this ?
Thanks

Keyur,
This is an interesting question. I have seen references where in it clearly says that only one ASM instance is required per node irrespective of number of databases on a node. But, I haven't seen a clear indication, wherein it is mentioned that you can't start more than 1 ASM instances on a node. Therefore, I thought, I would give it a shot, by attempting to bring up a second ASM instance and here is what I get:
SQL> startup nomount pfile=init+ASM5.ora
ORA-00304: requested INSTANCE_NUMBER is busy
SQL>
If I shutdown my ASM1 (first ASM instance) then it allows me to bring up the ASM5 instance. This leads me to believe that you can't startup up more than one ASM instance on a single node.
Here is a note, which mentions that you need only one ASM instance per node. https://metalink.oracle.com/metalink/plsql/docs/ASM%20best%20practices.pdf

Dear Sadiq,
From DB point of view there is no problem to install two separate databases
of DB2 on one machine. The DB2 source files are installed into different directories and will not
impact each other.
After installing the software, the DB2 instance called "db2<SID>' is
created with the DB2 version you choose. The installation procedure
depends on the SAP release.
Whether of not your machine is able to handle both systems running on one server depends on
the hardware and settings.

Two family home sharing one Verizon Fios network. I want to use my time capsule to boost the signal in my basement apartment while still using the Fios network for the apartment upstairs. Is this possible?

Hi there,
I just moved into a basement apartment in a two family home. We share internet and cable. The signal in my apartment is mediocre at best and I wanted to use my time capsule to boost the signal in my apartment while keeping their Fios network intact upstairs. Is there any way to do this without having to turn off the wifi in the Verizon actiontec router? Any help or tips would be extremely helpful. Thanks in advance.

The only way to boost signal with apple products is to another apple product.
Or run ethernet or some other replacement for wireless. eg EOP (homeplug) adapters. These are not foolproof though.. they depend on circuits being wired via simple fuses and can at times not work.
Your other choice is to get an Airport Express.. plug it into the FIOS router and use that to establish a network.. it can also be used as a wireless bridge in the downstairs area but you can pick whichever works the best. If your wireless is reasonable at least in one location downstairs any wireless bridge could do the same thing.. and plug into the TC for your downstairs wireless.

Install two Process Server on one machine

Hi everyone,
I would like to install two Process Server on only one server (machine). This machine will be use for two different environnements?
Do you think it's possible? and what would be the impact about this kind of installation?
If it's possible, the port used by the two Process Server will not be in conflict?
Thanks,
Regards,
Jean-Christophe

Hi,
With software trees I meant software installation directory trees, so say:
- /opt/redwood/dev for your development process server and
- /opt/redwood/test for your test process server
If you install in two different directories like above, because you want to be able to do independent upgrades, then it is recommended to have two network agents too on different ports, so these can be independently upgraded too. For future reference it then helps to name the services rwna_dev and rwna_test respectively in the above directory example.
If you need to run two process servers on the same box but connecting to the same repository, then you can use one software installation (f.i. /opt/redwood/server) and you need only one network agent.
Regards,
Anton.

Two apex instances on one machine

I am trying to create two apex instances using the embedded PL/SQL gateway on a single machine. I have two database instances up and running, one for development and one for production. I successfully installed apex 3.2.1 on the development instance, created some simple apps and everything seems to work as advertised, running from port 8080.
I installed 3.2.1 on my other instance and everthing went fine until I had to create a way to connect. My
select dbms_xdb.gethttpport from dual;
returned zero, so I knew I had to set a port to wake up the network services on the instance. That's where I have my question. I cannot find out whether I need to use port 8080 and somehow separate my apex instances based on the DAD or if I should use a separate port for each instance. I tried setting the httpport to 8090 on the new install and my listener shows it active, but when I hit it, I cannot get a response with ~/apex/apex_admin - just a browser password dialog.
The apex environment on the development install continues to work fine, responding to ~:8080/apex/apex_admin.
I am guessing that I have a logical gap somewhere. Where can I read about how to manage this kind of setup?
Thanks,
Brandt

Brandt:
You want to check if a DAD named 'apex' is configured in the Oracle instance where you have the http port set to 8090.
Login to this instance as the sys user and run this bit of pl/sql. It will display all DADS and their mappings
SET SERVEROUTPUT ON SIZE UNLIMITED
DECLARE
pths DBMS_EPG.varchar2_table;
dads DBMS_EPG.varchar2_table;
BEGIN
dbms_epg.get_dad_list(dads);
for i in 1..dads.count loop
    DBMS_EPG.get_all_dad_mappings (
       dad_name => dads(i),
       paths    => pths);
    DBMS_OUTPUT.put_line('Mappings for DAD'|| dads(i));
    FOR j IN 1 .. pths.count LOOP
       DBMS_OUTPUT.put_line(pths(j));
    END LOOP;
end loop;

Question on Oratab file when installing two Oracle instances in one machine

OS: AIX 5.3
DB version:10.2.0.1.0
I already have an instance of version 9.2 which is very important and which we don't want to upgrade and we wanted another test(unimportant) oracle instance called testdb_10gR2 of version 10.2.0.1.0 on the same machine.
So i installed 10.2.0.1.0 on a different ORACLE_HOME .Installation of the new 10.2.0.1.0 (testdb_10gR2) went ahead successfully and at the last step i have to log in as root and execute root.sh
I entered 'n' for the options "dbhome", "oraenv", "coraenv" as shown below so that the settings for our 9.2 instance (which is very important) will remain intact.
What would have happened if i entered 'y' ie. Overwrite ?
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u04/testdb_10gR2_Feb2009
Enter the full pathname of the local bin directory: [/usr/local/bin]: /usr/local/bin
The file "dbhome" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: n
The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: n
The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n) [n]: n
Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
During installEdited by: Citizen_2 on Jan 30, 2009 5:05 AM

'dbhome','oraenv','coraenv' are sripts used to set a proper environment (see the descriptions at the beginning of these scripts). These scripts rely on oratab (they check for existing SIDs), but answering 'Y' does not mean you will modifiy an existing oratab.
I think these scripts change rarely, so it's very likely overwriting the existing 9i scripts with the 10g scripts changes nothing. To be honest I don't use the scripts , so in my case 'Y' or 'N' doesn't matter. But important is you don't have to worry about 'oratab'.

IPhoto '09: Two Facebook users on one machine

Hello,
My wife and I each have a Facebook account. When I want to upload pictures on my Facebook page, I get an error message saying iPhoto cannot connect to the social network. This happens afer a session where my wife added pictures in her own Facebook account. Then, I have to reenter my Fb username and password in iPhoto.
When my wife wants to upload pics to Facebook, she has to deal with the same situation.
Is there something we're not doing the right way? Can't we just provide both accounts' details in iPhoto and live a happier life???
Thanks!

Thanks for the reply.
I'm sure there would be a better way to ask an user to provide the necessary authentication information, instead of the actual error message...
Maybe someday Apple will consider the fact that more than one member of a family can use a computer and online services.
But I appreciate the reply. Thanks

Possible to install two groupware connectors on one machine/system?

Hi gurus,
we want to save the money for a new machine, so I'm currently looking to get a second groupware connector installation done on the same machine. Anyone having experience with that? Is it even possible?
The setup.exe does not really offer to do a second groupware connector installation for exchange. Even if that would be possible I fear the created services for our machine (SAP MS Exchange Groupware Connector 2.1) will be overwritten by the second installation?
Torsten

Torsten,
I know from how the Lotus Notes version of the connector works, it just wouldn't work because of how it uses the Lotus Notes libraries. For exchange I'm not sure if there is as tight of integration. The connector is relatively light weight, so have you considered piggy backing it on another box such as a SAP webdispatcher or something else. You could also look at using a VM as the requirements for the connector aren't that much for a test system.
Take care,
Stephen

DTRShell and 2 DTRs on one machine

Hi,
I'm playing around with the DTR and have two DTRs sitting on one machine in two instances. One is on instance 00 and the other one on 03. When I open the dtrshell it connects to the instance 00 by default. How can I connect to the DTR on instance 03???
Kind regards,
Heiko

Hello Heiko,
the DTRs on the 00 and 03 instance listen to different HTTP ports, i.e. 50000 for instance 00 and 50300 for 03 by default ( 50000 + instance_number*100 ).
Localize the files servers.xml and clients.xml on your system (usually in the .dtr folder in your home directory) and create corresponding entries for your second instance. The <client> entry with attribute "active=true" is the default client.
Best Regards
Michael

Have multiple iTunes libraries on one machine?

Hi,
I want to have multiple iTunes libraries on one machine (with two different hard drives, internal fore mp3s and external for AAC files). One library is composed of mp3s for an iPod, I want the other library to have AAC audio files for burning CDs. I would rather the libraries not be mixed.
I have read the article (#301748) for migrating an iTunes library and am preparing to migrate one of the libraries on to a external hard drive.
I have read about using Libra to maintain two different libraries on one machine. I was wondering if anyone does this and if they have encountered any problems? Is there a better solution?
Thank you,
TPK

It's one thing to want two music libraries on one machine and another to want two music libraries on one user account. For the latter, here's what I've done.
I created folders in my iTunes folder called, say, Main Library Folder and Second Library Folder. (These could be anywhere you find convenient.) I dragged my regular iTunes Library file into the Main Library Folder. Then I opened iTunes and created my second music library. When I finished that, I closed iTunes and dragged the just-created iTunes Library file into the Second Library Folder.
If I want to use my main iTunes library, before opening iTunes I drag an alias (Cmmd-Option-drag) of the iTunes Library file from the Main Library Folder into the iTunes folder. Then, when I open iTunes, iTunes reads my main library file. And of course, it works the same way for the second library.
Of course, you could just shuffle the actual library files into position in the iTunes folder from their holding areas, but I strongly preferred to get myself into the habit of relying on aliases, so I could leave the actual library file alone in their respective folders. You most definitely would not want to accidentally overwrite one of your iTunes Library files.
I'm sure one of the shareware products would do a more elegant job, but this just shows you that it's not a difficult process.
The alternative is to set up separate user accounts to access different libraries on the same machine. This has real benefits and, to me, should be the first option one considers. It's easier on the brain, as it sticks to iTunes' one-user-one-library model, and there's absolutely no risk of getting libraries confused. Fast User Switching on the Mac makes going back and forth between accounts easy. But if you really want to avoid using different accounts, and it's only you that has to keep things straight, the approach of jumping back and forth between different libraries in the same user account should be OK.

Multiple remote home directory users logged into one machine?

Hello,
Just wondering if it's possible to have two or more users logged into the same machine at the same time. Each user has a home directory located on an XServe RAID connected to an XServe.
We have a new employee who is needing to toggle back and forth between his account and an account that belongs to a previous employee.
So far I've only had success logging in one remote home directory user, and a user account local to the machine. Making.. two users logged in on the same machine at the same time.
Anyone able to offer some insight? thanks!

The way afp works, you won't be able to log in more than one user with a remote home directory on any one machine at a time. This is a known limitation.
If you need access to more than one account at a time, you could copy the home directory of the old user onto the local machine and set up a local account with it. Or you could give the new user a copy of the old home directory if it's just a matter of file access.
Hope this helps,
Andrew

One lieneter for two oracle homes?

Hi
If I have two Oracle Homes on the same servers (say, 10.2.0.4 and 10.2.0.5), do I need to configure two listeners (one for databases of each Home) OR one listener (from the higher version Oracle home probably) will be good enough? If one listener is enough, is there special configuration for such case?
Best regards

No, the listener from the most recent release would be sufficient for all the databases running on the machine.
