How To Set up Oracle 12c On Linux – I am very excited concerning the presentation I will be doing with Kellyn PotVin-Gorman on the RMOUG Coaching Days subsequent month, referred to as Efficiency Analytics: Visualizing the Energy of the AWR Warehouse. Okay…in the event you insist…I will provide you with a fast plug. Kellyn and the workforce have been engaged on creating the AWR Warehouse characteristic of Enterprise Supervisor to retailer the enterprise historical past of the Automated Workload Repository (AWR) in a single repository… all managed by EM. Nicely good proper? I believed… it might be good to see what OBIEE 12c can do in opposition to AWR Warehouse… and effectively, a proposal was born.
For this presentation, I would like an Oracle 12c database working on Home windows. The Home windows half is definitely solely a half-truth… You may simply construct a database, EM, AWRW and OBIEE 12c on Linux… it is an ordinary working situation for many of our prospects. However for OBIEE addicts… you already know that, sadly, metadata layer growth is being performed utilizing a Home windows-only device referred to as the administration device. I need one other machine for every thing that I can use to simply show the metadata layer throughout manufacturing… and I do not like the necessity to run two separate machines throughout demo if I can keep away from it.

How To Set up Oracle 12c On Linux
I’ve a brand new Apple MacBook Professional. I am not bragging…this is essential, however you need to belief me for a second. Anyway… I exploit VMware Fusion at any time when I can… In fact, I additionally use VirtualBox fairly a bit, since all Oracle machines include ViritualBox, together with the wonderful SampleApp and Large Knowledge Lite VM. Nonetheless, for this process I began with VMware Fusion, created a Home windows 7 working system, downloaded the Oracle Database 12c implementation recordsdata, and began the set up. I select the choice “Create and configure the database”, and the primary set up of the binaries was accomplished with out issues, however then the Database Configuration Wizard began (step 8, precisely 83% of all the course of) after which it falls. Immovable. The very last thing within the log file was “Beginning the Database Creation Wizard…”, then silence. Cricket. I gave him a variety of time to complete… a variety of time. I helped the youngsters with homework, folded laundry, and watched the newest episode of Mr. Robotic. Nonetheless… it did not go over 83%.
The Straightforward Means To Get Began With Oracle Database:virtualbox!
All through the troubleshooting course of, I’ve tried the next, in numerous steps and combos, with growing ranges of frustration and desperation:
None of this labored. I bought the very same consequence each time. I can not create a database. Nonetheless, it wasn’t till I began digging into answer #8 above that I began to get some clues about the issue.
So the subject of this text is a bit attention-grabbing… I do know that Oracle Database 12c will work on Home windows… as a result of I’ve put in and configured it many instances. I’ve performed it earlier than on VMware Fusion and VirtualBox, and I’ve performed it lately on Amazon EC2. Whereas I used to be constructing my new Efficiency Analytics VM (ultimate plugin, I promise), I launched one of many Amazon EC2 situations working to carry out a reliability check and I did not get nothing. Nothing attention-grabbing in any respect. No loopback adapters, no ORACLE_HOSTNAME, no scientist recordsdata. It is simply an Oracle 12c database that works nice and there is nothing particular about it. I went again to analyze one in all my defective machines the place I had put in solely the Oracle database software program, however not working DBCA, and eventually bought the clue. Not one of the on-line instruments truly work. I attempted lsnrctl and tnsping within the command line and despite the fact that they ran and gave the anticipated response, they did not end and stayed there.
So, as an alternative of specializing in database configuration, I began serious about database set up… which till then I took with no consideration. I knew one thing was flawed with these TNS providers…like they weren’t compiled 100% appropriately. And I suspected the issue was virtualization associated… which was my second clue.
Oracle Database Templates For Oracle Linux Kvm Now Obtainable!
Again in October, I used to be attempting to put in Oracle Database 12c on Oracle Linux 7.0, and bumped into what seemed to be a virtualization-only situation with Linux as effectively… this was uncovered by the wonderful work of Oracle Base Tim Corridor. Tim had identified an issue the place the Perl set up for the 12c database was corrupted and wanted to get replaced. Tim did not go into the main points of the issue, however he did discuss with a publish by Laurent Leturgez that describes a workaround for downloading a brand new Perl binary to exchange the present Oracle one. That solved the Linux set up on the time, however now with the Home windows situation, I used to be questioning in the event that they have been one way or the other unrelated, particularly since each appeared to focus on VMware and VirtualBox. I revisited Laurent on this subject and located a current replace on the web page that referenced Danny Bryant’s publish explaining that the issue was associated to newer variations of the virtualization software program in addition to the standing cache. 4 on previous Intel chips. And the final a part of the sport was this publish by Mike Dietrich at Oracle that actually opened up the case.
As Mike defined…it isn’t virtualization software program particularly…it appeared prefer it. As a substitute, it’s associated to the brand new Iris Professional processors utilized by Apple within the new MacBook Execs. Oracle software program is just not ported to MacOS, so the one technique to apply it to these new Iris Professional chips is to make use of virtualization software program. The hyperlinks listed above have extra data…however I will quote a small part from Mike beneath for context. However bear in mind… whenever you speak concerning the Perl binary… perceive that it isn’t simply Perl on Linux… but additionally a compilation of many TNS instruments on Home windows, it appears, and who is aware of greater than that:
Present pondering is that Intel CPUs with Iris Professional graphics are affected. Iris Professional represents eDRAM (built-in DRAM) which is reported because the fourth stage cache within the CPUID. We’ve confirmed that Crystal Nicely and Broadwell CPUs with Iris Professional are affected. The Xeon E3–1200 v4 household may additionally be affected. There appears to be a bug within the Perl binary. It hyperlinks to legacy code from the Intel compiler suite and makes optimizations primarily based on CPU traits. The most recent Intel CPUs have 4 cache specs. The individuals who discovered this used Digital Field VBox 5.0.x and forwarded this data to the visitor. This causes an issue within the Perl code. You will not see it in VBox 4.3 as this model does not move data to the host. However truly it appears that evidently this downside is unbiased of Digital Field or another virtualization software program. On this case, it solely occurs when many individuals use VBox on Mac and a few Macs have this new sort of CPU.
The rationale I had not seen this situation earlier than when utilizing Oracle Database 12c on VMware or VirtualBox is that these stage 4 cache instructions weren’t handed on to earlier variations of the virtualization software program, or the MacBook Professional that I had use it at the moment. not. geared up with an Iris Professional chipset. Though Danny and Mike talked about above supplied an answer that lastly labored for me… I will embody it right here as effectively. In VirtualBox, run the next command line for every VM that should have an Oracle database put in. On this instance, “awrw” is the identify of my VirtualBox VM:
How To Set up Oracle Database 18c Xe On Home windows
These adjustments will persist throughout VM clones… so you possibly can run the instructions as soon as on a Home windows VM and use that VM because the supply for all future clones. I have never discovered an answer corresponding to VMware…perhaps somebody is aware of somebody who is aware of somebody who is aware of a trick.
