- \n
- Install the OS on the first node<\/li>\n
- Add the shared disks<\/li>\n
- Install the clusterware in RAC mode on on the first node only<\/li>\n
- Remove temporarily the shared disks<\/li>\n
- Clone the server as linked clone as many times as you want<\/li>\n
- Reconfigure the new nodes with the new ip and naming<\/li>\n
- Add back the shared disks on the first node and on all other nodes<\/li>\n
- Clone the GI + database homes in order to add them to the cluster<\/li>\n<\/ul>\n
Using this method the Oracle binaries (the most space consuming portion of the RAC installation) are installed and allocated on the first node only.<\/p>\n
The long step list<\/strong><\/p>\n
Actually you can follow many instruction steps from the RAC Attack 12c book<\/a>.<\/p>\n
- \n
- Review the HW requirements<\/a>\u00a0 but let at least 3Gb RAM for each guest + 2Gb more for your host (you may try with less RAM but everything will slow down).<\/li>\n
- Download all the SW components<\/a> , additionally you may download the latest PSU (12.1.0.1.2) from MOS<\/a>.<\/li>\n
- Prepare the host<\/a> and install linux<\/a> on the first node. When configuring the OS, make sure you enter all the required IP addresses for the additional nodes. RAC Attack has two nodes collabn1, collabn2. Add as many nodes as you want to configure. As example, the DNS config may have four nodes<\/li>\n<\/ul>\n
collabn1 A 192.168.78.51\r\ncollabn2 A 192.168.78.52\r\ncollabn3 A 192.168.78.53\r\ncollabn4 A 192.168.78.54\r\ncollabn1-vip A 192.168.78.61\r\ncollabn2-vip A 192.168.78.62\r\ncollabn3-vip A 192.168.78.63\r\ncollabn4-vip A 192.168.78.64\r\ncollabn1-priv A 172.16.100.51\r\ncollabn2-priv A 172.16.100.52\r\ncollabn3-priv A 172.16.100.53\r\ncollabn4-priv A 172.16.100.54\r\ncollabn-cluster-scan A 192.168.78.251\r\ncollabn-cluster-scan A 192.168.78.252\r\ncollabn-cluster-scan A 192.168.78.253<\/pre>\n
- \n
- \u00a0Create the shared disks<\/a> and configure the persistent storage naming<\/a> using udev.<\/li>\n<\/ul>\n
At this point, the procedure starts differing from the RAC Attack book.<\/strong><\/p>\n
- \n
- Skip the creation of the second host and go directly to the VNC Server setup<\/a>.<\/li>\n
- Install the Grid Infrastructure<\/a> and the Database software <\/a>using only the first node.<\/li>\n
- You may want to install the latest PSU (12.1.0.1.2), use my previous post as guideline<\/a><\/li>\n
- Once the GI + DB are installed correctly, stop and disable the crs on the first node:<\/li>\n<\/ul>\n
# <GIHOME>\/bin\/crsctl stop crs\r\n# <GIHOME>\/bin\/crsctl disable crs\r\n# shutdown -h now<\/pre>\n
- \n
- \u00a0Go to the VirtualBox VM settings and delete all the shared disks
![\"2014_03_16_22_05_26_Oracle_VM_VirtualBox_Manager\"](\"https:\/\/www.ludovicocaldara.net\/dba\/wp-content\/uploads\/2014\/03\/2014_03_16_22_05_26_Oracle_VM_VirtualBox_Manager.png\")
<\/a><\/li>\n- \u00a0Clone the first server as linked clone (right-click, clone, choose the name, flag “Linked Clone” as many times as the number of additional servers you want.<\/li>\n<\/ul>\n
![\"2014-03-16](\"https:\/\/www.ludovicocaldara.net\/dba\/wp-content\/uploads\/2014\/03\/2014-03-16-22_09_42-Clone-Virtual-Machine.png\")
<\/a><\/p>\n<\/p>\n
- \n
- By using this method \u00a0the new servers will use the same virtual disk file of the first server and a second file will be used to track the differences. This will save a lot of space on the disk.<\/li>\n
- Add back the shared disks to all the servers.<\/li>\n
- Start the other nodes and configure them following the RAC Attack instructions<\/a> again.<\/li>\n
- Once all the nodes are configured, the GI installation has to be cleaned out on all the cloned servers using these guidelines:<\/li>\n<\/ul>\n
cd $GI_HOME\r\nrm -rf log\/$(hostname)\r\nrm -rf gpnp\/$(hostname)\r\nfind gpnp -type f -exec rm -f {} \\;\r\nrm -rf cfgtoollogs\/*\r\nrm -rf crs\/init\/*\r\nrm -rf cdata\/*\r\nrm -rf crf\/*\r\nrm -rf network\/admin\/*.ora\r\nrm -rf crs\/install\/crsconfig_params\r\nfind . -name '*.ouibak' -exec rm {} \\;\r\nfind . -name '*.ouibak.1' -exec rm {} \\;\r\nrm -rf root.sh*\r\nrm -rf rdbms\/audit\/*\r\nrm -rf rdbms\/log\/*\r\nrm -rf inventory\/backup\/*\r\nchown -R oracle:oinstall \/u01\/app\r\n\r\nrm -f \/etc\/init.d\/ohasd \r\nrm -rf \/etc\/oracle \r\nrm -rf \/u01\/app\/oraInventory\/*<\/pre>\n- \n
- Then, on each cloned server, run the perl clone.pl as follows to clone the GI home, but change the LOCAL_NODE accordingly (note: the GI Home name must be identical to the one specified in the original installation!):<\/li>\n<\/ul>\n

I know it seems a little complex, but if you have several nodes this is dramatically faster than the standard installation and also the space used is reduced. This is good if you have invested in a high-performance but low-capacity SSD disk like I did :-(.<\/p>\n
Hope it helps, I paste here the official documentation links that I’ve used to clone the installations. The other steps are my own work.<\/p>\n

Recently I’ve had to install a four-node RAC cluster on my laptop in order to do some tests. I have found an “easy” (well, easy, it depends), fast and space-efficient way to do it so I would like to track … Continue reading

- As result, you should be able to seen all the cluster resources started correctly on all the nodes.<\/li>\n<\/ul>\n
- \u00a0and finally, run the GI root.sh on each new node to finalize their inclusion in the cluster!! \ud83d\ude42<\/li>\n<\/ul>\n
- \u00a0On each new node run also the updatenodelist and the DB root.sh command to update the node list for the DB home:<\/li>\n<\/ul>\n
- \u00a0Then clone also the DB Home (again, run it on each new server and specify the same DB home name that you have used in the original installation):<\/li>\n<\/ul>\n
- from the first server copy these files on all the other nodes:<\/li>\n<\/ul>\n
- \u00a0Then, on the first node (that you have started and you have reactivated the clusterware stack on it with crsctl enable crs \/ crsctl start crs ;-)), run this command to add the new nodes in the definition of the cluster:<\/li>\n<\/ul>\n
- Once all the nodes are configured, the GI installation has to be cleaned out on all the cloned servers using these guidelines:<\/li>\n<\/ul>\n
- \u00a0Clone the first server as linked clone (right-click, clone, choose the name, flag “Linked Clone” as many times as the number of additional servers you want.<\/li>\n<\/ul>\n
- Install the Grid Infrastructure<\/a> and the Database software <\/a>using only the first node.<\/li>\n
- Skip the creation of the second host and go directly to the VNC Server setup<\/a>.<\/li>\n
- Download all the SW components<\/a> , additionally you may download the latest PSU (12.1.0.1.2) from MOS<\/a>.<\/li>\n
- Review the HW requirements<\/a>\u00a0 but let at least 3Gb RAM for each guest + 2Gb more for your host (you may try with less RAM but everything will slow down).<\/li>\n
