When implementing Database as a Service (DBaaS) and/or Snap Clone, a common request was for a way to hide the other service types like IaaS, MWaaS, etc from the self service portal for the end users. Before EM12c R4, there was no way to restrict the portal view. Essentially, any user with the EM_SSA_USER role would be directed to the self service portal and would then be able to see all service types supported by EM12c.
Surprisingly, a popular question posted on our internal forum is about the possibility of using the Enterprise Manager (EM) Job System to replace customer’s numerous cron jobs. The answer is obviously YES! I say surprisingly because the EM Job system has been in existence for around 10 years (I believe since EM 10.2.0.1), and my hope was that, by now, customers would have moved to using more enterprise class job schedulers instead of cron.
This is part 2 of my two part blog post on
Job System Easter Eggs (hidden features). The two features being covered are:
So you just installed a new EM12c R4 environment or upgraded your existing EM environment to EM12c R4. Post upgrade you go to the Job System activity page (via Enterprise->Job->Activity menu) and view the progress details of a job. Well nothing seems to have changed, its the same UI, the same multi-page drill down to view step output, same no. of clicks, etc. Wrong!
I have a deadlock being reported in my 3-node Oracle RAC database (version 22.214.171.124) as can be seen in the Alert Log. Being that this is an Oracle RAC database, resources are managed globally and the Lock Manager Daemon (LMD) gets involved. The message in the alert log pointed me to a LMD trace file which contained this Global Wait-For-Graph (GWFG).
While we spend a lot of time developing GUI for our private cloud features – like the self service portal, setup screens, etc, a large percentage of our customers use these features via our APIs, both EMCLI and REST based.
Q: So why would anyone not use the out of the box cloud (self service) portal and use the APIs instead?
A: Well, there are many reasons:
In the days past, everybody in EM used to end up with Super Administrator privileges due to lack of granularity in permissions. Not any more! Now we have more permissions than you know what to do with, but that’s another blog topic all together!
Here’s a quick list of activities that one might still need Super Administrator for – note these are all considered EM administration activities and most are accessed through the Setup menu:
