How do I remove Yosemite installation partition

I have a 2009 iMac with the primary OS disk being an SSD and the secondary disk as my Home drive. I downloaded Yosemite via the App Store but never installed it. Instead, I created a bootable installation USB stick in order to perform a fresh installation on this iMac. After successful "clean" installation to the primary SSD, I noticed there is an approximate 100GB partition on my secondary Home HD called, "Install OS X Yosemite". How do I remove this partition without affecting all the contents on my HD?
Thank you in advance.

Please open Disk Utility, select the primary drive entry (out-dented) then click on the Partition tab in the main window. Take a screenshot and post here.
To post screen shot do this:
Press COMMAND-SHIFT-4 which will change the cursor to crosshairs.
Hold down the mouse button and use the crosshairs to select the part of the screen you wish to capture.
Release the button and the image will be saved to your Desktop.

How do you remove software installations???

Hello.
I am coming from the PC world. How do you UNinstall software on a MAC? There's no uninstall program. How do you make sure that all associated files and 'trash' are removed with the software? Is there a registry to manipulate? I've used Linux, and I don't see a package manager that takes care of the housekeeping. Anyway, you get the idea.
Informaion greatly appreciated.
Thank you,

Hello, welcome to the Mac world.
Generally speaking, all you need to do to uninstall a program is drag it to the trash and empty it. If the program is in it's own folder, like Photoshop for example, then you can trash the whole folder and its related files. Some programs may leave behind small settings files that hold your Preferences but they are small and it doesn't hurt to leave them. Preferences and other settings are kept in either the Preferences or Application Support folders - they are located in either the Library folder or youruser/Library folder.
Usually the case is this - if you install a program by manually copying it to the Applications folder, then all you have to do is drag it out to deinstall. If installing requires the use of an installer program, then try running the installer again to see if it offers an uninstall feature.
There is no registry to muddle with - that's a Windows-only "feature".

Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. (The results from mydigitallife and Major Geeks are worth checking.)
After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove".
Quit out of CleanUp. Restart the PC, and try another iTunes install. Does it go through properly this time?

How can I remove asm and ocr installation in AIX?

Hi,
I try to install single instance with using ASM in AIX.
But I did not make successfully.
Now I want to remove ASM and OCR installation then
I will plan to make new clear installation.
How can I remove asm and ocr ??
Or How can I control my removing is fully correct ?

1) ASM Instance Clean-Up Procedures
Stop all of the databases that use the ASM instance that is running from the Oracle home that is on the node that you are deleting.
On the node that you are deleting, if this is the Oracle home which from which the ASM instance runs, then remove the ASM configuration by completing the following steps. Run the command srvctl stop asm -n node_name for all of the nodes on which this Oracle home exists. Run the command srvctl remove asm -n node for all nodes on which this Oracle home exists. If there are databases on this node that use ASM, then use DBCA Disk Group Management to create an ASM instance on one of the existing Oracle homes on the node, restart the databases if you stopped them.
If you are using a cluster file system for your ASM Oracle home, then ensure that your local node has the $ORACLE_BASE and $ORACLE_HOME environment variables set correctly. Run the following commands from a node other than the node that you are deleting, where node_number is the node number of the node that you are deleting:
rm -r $ORACLE_BASE/admin/+ASMnode_number
rm -f $ORACLE_HOME/dbs/*ASMnode_number
If you are not using a cluster file system for your ASM Oracle home, then run the rm or delete commands mentioned in the previous step on each node on which the Oracle home exists.
2) Deleting an Oracle Clusterware Home Using OUI in Silent Mode
!!! Oracle recommends that you back up your voting disk and OCR files after you complete the node deletion process.
If you ran the Oracle Interface Configuration Tool (OIFCFG) with the -global flag during the installation, then skip this step. Otherwise, from a node that is going to remain in your cluster, from the CRS_home/bin directory, run the following command where node2 is the name of the node that you are deleting:
./oifcfg delif –node node2
Obtain the remote port number, which you will use in the next step, using the following command from the CRS_home/opmn/conf directory:
cat ons.config
From CRS_home/bin on a node that is going to remain in the cluster, run the Oracle Notification Service Utility (RACGONS) as in the following example where remote_port is the ONS remote port number that you obtained in the previous step and node2 is the name of the node that you are deleting:
./racgons remove_config node2:remote_port
On the node to be deleted, run rootdelete.sh as the root user from the CRS_home/install directory. If you are deleting more than one node, then perform this step on all of the other nodes that you are deleting.
From any node that you are not deleting, run the following command from the CRS_home/install directory as the root user where node2,node2-number represents the node and the node number that you want to delete:
./rootdeletenode.sh node2,node2-number
If necessary, identify the node number using the following command on the node that you are deleting:
CRS_home/bin/olsnodes -n
Perform this step only if your are using a non-shared Oracle home. On the node or nodes to be deleted, run the following command from the CRS_home/oui/bin directory where node_to_be_deleted is the name of the node that you are deleting:
./runInstaller -updateNodeList ORACLE_HOME=CRS_home
"CLUSTER_NODES={node_to_be_deleted}"
CRS=TRUE -local
Deinstall the Oracle Clusterware home from the node that you are deleting using OUI as follows by running the following command from the Oracle_home/oui/bin directory, where CRS_home is the name defined for the Oracle Clusterware home:
./runInstaller -deinstall –silent "REMOVE_HOMES={CRS_home}"
Perform step 9 from the previous section about using OUI interactively under the heading "Deleting an Oracle Clusterware Home Using OUI in Interactive Mode".

How to change of NAME and IP after RAC installation.

Hi Friends,
I have a challenge here...Would appreciate if anyone can help me..
I have to install 10.2.0.3 Oracle RAC on windows 2003 server 64 bit.
My issue is now the server names and ips are set and I am going to install the RAC.
But the client need is that after one month, they need to change the names and ips of the servers (a one time change).
Because according to their server naming standards, current production servers are having the acceptable names and ips.
The installation was on a 32 bit OS, so they are facing out of process memory errors. Thats why they are going to 64 bit OS on new servers.
After the new servers are ready, the data will be migrated to new server. After a month, they need to change the names of new servers to that of the old (current production) servers.
Could anybody help me by giving me information about how to change the NAME and IP after a RAC installation ?
Any metalink notes or commands as it is........
Thank you,
Mahesh.

Hi,
You can change the IP later but you can not change the hostname of the system.
You have to install CRS freah if you want to change the hostname of the system.
Please let us know which IP you want to change.
You can see the metalink Note.276434.1 for VIP or VIP hostname change.

CRS-0213 error during 10g RAC installation

The two nodes are 2 Sun machines. The Oracle CRS installation went smoothly without incidents. I then kicked in the 10g DB RAC installation. At the end of the installation, I got error. I took a snapshot here:
http://bostonfx.com/temp/ora10g.gif
Any advise is much appreciated,
Lucas

Hi Lucas -
This sounds simliar to Bug 3584146 PRKR-1008 adding instance to CRS via SRVCTL. The published workaround follows:
The workaround is to give permissions on the vip resources for all oracle users on the machine.
crs_setperm ora.<nodename>.vip -u user:<orauser1>:rwx
crs_setperm ora.<nodename>.vip -u user:<orauser2>:rwx
Repeat this for all oracle users on the system.
Hope this helps

How do you remove previous Oracle Database installations from your registry

HI,
I am trying to reinstall Oracle 9i and Oracle 9i developer on windows XP home and i have used the OUI to uninstall both programs. I tried re-installing the database and Oracle universal Installer gave me a message indicating i have 2 previous databases. Besides taking a different Oracle Home and removing the Oracle folder on the hard disk, how can i remove the Oracle Entries in the registry so that the computer is free of Oracle?
Thanks

if u reinstall oracle and before that u have to delete the oracle related previous installation information from your registry.for that go to registry and open
1)hkey_local_machine-software-in that delete oracle folder
2)hkey_local_machine-system-controlset001-in that delete the old database service information,listener info._lo
3)hkey_local_machine-system-controlset002-in that also delete the old database service,listener information.

I was told by apple support that I have malware on my iMac that is trying to convince me to buy their cleanup software. I was told it was a scam and my computer is not infected, but they want my credit card info. How do I remove the malware?

How do I remove malware from my iMac?

you can do a Google search for "anti-virus" and "mac" and see what you come up with. I think Norton now makes a program for mac with anti-trogan and anti-rootkit detection, and hopefully it'll get better with more time and more complaints
As laverne's mom said, Norton's should never be installed on any Mac - period. I would not let it within 10 feet of my machines. It creates so many problems, it should be considered malware. If you must install AV software, try ClamXAV; it is free. However, there are no viruses for Mac; the current problem is a trojan and if due diligence is observed, there is no problem.
