11gR2 should be retired now, and there is normally no need to deploy a new database using this version anymore. But in the real world, you may need to do that for some reasons. 11gR2 is no more supported on Oracle Database Appliance, but this is the way you can setup a “brand new” Oracle Database 11gR2 environment on ODA. Obviously, I would only recommend doing this if there is no other options.<\/p>\n\n\n\n
The first ODAs were designed for 11gR2, but support for this version disappeared nearly 2 years ago. There are still ODAs running 11gR2 databases, but it’s mostly old ODAs deployed several years ago. Applying the latest ODA patch on top of 11gR2 databases is not a problem, your 11gR2 databases won’t be patched although every other components will. Therefore, running the most recent 19.17 patch with 11gR2 databases is OK. But deploying a new infrastructure with X9-2 ODAs running 11gR2 databases wouldn’t make sense and is not supported. Furthermore, ODA development’s team now focus on modern features, mainly tied with Oracle 19c. Don’t expect to run these new features on old 11gR2 databases. Most of the time it won’t work correctly as Oracle doesn’t bother anymore testing on 11gR2.<\/p>\n\n\n\n
If you absolutely need 11gR2, you currently have 2 solutions.<\/p>\n\n\n\n
The first one is deploying an old set of binaries from an old patch, for example 19.10. It’s the easiest way to put 11gR2 on your ODA:<\/p>\n\n\n\n
cd \/opt\/dbi\/\nunzip p23494997_1910000_Linux-x86-64.zip\nodacli update-repository -f \/opt\/dbi\/odacli-dcs-19.10.0.0.0-210115-DB-11.2.0.4.zip \nodacli create-dbhome -v 11.2.0.4.210119\nodacli list-dbhomes \n\nID Name DB Version Home Location Status\n---------------------------------------- -------------------- ---------------------------------------- --------------------------------------------- ----------\n2a00d3bb-b042-4720-94a2-bef13bfaf5f5 OraDB19000_home1 19.15.0.0.220419 \/u01\/app\/odaorahome\/oracle\/product\/19.0.0.0\/dbhome_1 CONFIGURED\n4f56e25e-e228-4cc3-b827-b15b66c67143 OraDB19000_home4 19.16.0.0.220719 \/u01\/app\/odaorahome\/oracle\/product\/19.0.0.0\/dbhome_4 CONFIGURED\n306d949e-6a61-4d7f-83e2-b023a9c47586 OraDB11204_home2 11.2.0.4.210119 \/u01\/app\/odaorahome\/oracle\/product\/11.2.0.4\/dbhome_2 CREATING<\/code><\/pre>\n\n\n\n<\/p>\n\n\n\n
The second one we will focus on is creating a new user-managed VM and manually deploy an 11gR2 DB home. I would definitely prefer this solution because I don’t want to use unsupported version on my ODA: I want to keep everything clean and supported. Creating a user-managed VM needs some work, but this VM won’t have any link to my ODA system, everything will be running on its own inside the VM.<\/p>\n\n\n\n
License considerations<\/h2>\n\n\n\n
You should be careful when using user-managed VMs with Oracle databases inside. If you run on Standard Edition, you normally have 1 license per socket on your system, and you can use as may cores as you want. When using Enterprise Edition, you will limit the available number of cores on your ODA with odacli update-cpucore, or you will use CPU Pools for DB Systems and run all your DB Systems in these CPU Pools. Configuring a VM CPU pool (which is different from DB Systems’ CPU pool) for databases in user-managed VMs is not compliant with the Oracle licensing model. You’d better limiting the total CPU-cores of your ODA in this case. For example, if you need 6 cores for 19c DB Systems and 2 cores for your 11gR2, configure 8 cores on your ODA with odacli update-cpucore and then configure the 2 CPU pools accordingly.<\/p>\n\n\n\n
Test environment<\/h2>\n\n\n\n
My test environment is based on a brand new ODA X9-2S deployed with 19.16 and using Standard Edition. I will use 19c DB Systems for most databases, and I will need a user-managed VM for 11gR2. The purpose of this user-managed VM is to decomission an old 11gR2 server and put all Oracle databases into the ODA. The application linked to this 11gR2 database will also be decomissioned, but later. It’s why there is no plan to migrate this database to a newer version.<\/p>\n\n\n\n
Setting up the user-managed 11gR2 VM<\/h2>\n\n\n\n
I will need a VM CPU pool for this “old” system:<\/p>\n\n\n\n

I will use an Oracle Linux distribution provided as an ISO file. Creating this VM will create a boot disk on the VM storage VMsDATA, and connect the 2 vdisks previously created. I will use my ODA’s IP address to map the VNC port.<\/p>\n\n\n\n

Now I can use a VNC client connected to 10.146.107.31:5903 and deploy a Linux distribution. I would recommend using the same OS as your ODA, meaning an Oracle Linux 7.9, but you can use an older one if needed. Linux setup on this VM is quite typical, additional settings and packages will be deployed using preinstall package provided by Oracle.<\/p>\n\n\n\n
Once the Linux is deployed, let’s check the disks and configure LVM according to OFA naming:<\/p>\n\n\n\n

I will mount this ISO file, configure a local repository on this ISO, and install the preinstall package. Other packages will be needed for 11gR2:<\/p>\n\n\n\n
mkdir \/install\r\nscp root@10.168.1.54:\/mnt\/nas\/V1009690-01.iso \/install\/\r\n\r\n\u2003\r\nmkdir \/mnt\/iso\r\nmount -o loop \/install\/V1009690-01.iso \/mnt\/iso\r\nrm -f \/etc\/yum.repos.d\/*\r\nvi \/etc\/yum.repos.d\/local-oel7.repo\r\n[OEL790]\r\nname=Oracle Linux 7.9 x86_64\r\nbaseurl=file:\/\/\/mnt\/iso\r\ngpgkey=file:\/\/\/mnt\/iso\/RPM-GPG-KEY\r\ngpgcheck=1\r\nenabled=1\r\n\r\nyum install oracle-database-preinstall-19c.x86_64\r\n...\n\nyum install compat-libstdc++-33-3.2.3-72.el7.x86_64\r\nyum install gcc-4.8.5-44.0.3.el7.x86_64\r\nyum install gcc-c++-4.8.5-44.0.3.el7.x86_64\r\nyum install mlocate\r\n<\/code><\/pre>\n\n\n\nNow I will do the 11gR2 setup using an image from the old system and the cloning method: I don’t want any changes regarding the binaries.<\/p>\n\n\n\n

Next steps<\/h2>\n\n\n\n
The system is now deployed and ready to host a first database. Creating a database is done by using dbca or by restoring a database from a backup. Using a backup is definitely the best idea to keep the database as close as the source one. You may need to use db_file_name_convert to remap the old datafile structure to the new one. I would probably create a pfile from the source database, make the needed changes and start my new instance with this pfile.<\/p>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
Only consider this solution if no other one is possible. Remember that it comes without any support and without any performance guarantee. For sure, I wouldn’t recommend using this solution for a production database, and I definitely advise migrating all your old databases to 19c. Don’t forget that 11gR2 is more than 15-year old now, and you shouldn’t deploy it in 2023.<\/p>\n","protected":false},"excerpt":{"rendered":"
