Hi Finn,

Did you just apply the 13584107 patch to resolve this? We applied the patch but we are still getting alerts from our targets once the blackout is over (since the database went down during the blackout). We do not take our agent down.

Thanks,
Mike

Yes it's fixed in 12c. Unfortunately, sometimes, when you take the agent down and then bring it back up the targets monitored by the agent goes into a "warning" state with a message of "agent down" instead of going into a agent unreachable state as they should. The rulesets handle these 2 status' differently which will most likely result in your oncall DBA getting an alert about the status of the targets followed by another alert that the status of the target is now up.

I have a severity 2 SR open about this currently.

Finn

We have been dealing with this blackout issue as well. I was thrilled to find this morning that there looks to be a patch to fix this issue in 12.1.0.1.

Patch 13584107: CRITICAL ALERT IS TRIGGERED WHEN BLACKOUT ENDED EVEN THOUGH TARGET REMAIN UP

We have been moving off of EM10g and to EM12c and have been happy with the it. I would recommend the upgrade to EM12c, except there is an issue that causes an alert to get sent out when a blackout ends. I believe this is a showstopper to anyone who uses EM12c to page and utilizes some cold backups as well. It has caused us to keep our production in EM10g while monitoring DEV in EM12c. If anyone knows a workaround to this issue please let me know.

I would love to try out the automated patching features, but unfortunately we are not licensed for it. It does not look like you are licensed for it either since I do not believe it is not included in the diagnostics + tunning packs. Please see "Lifecycle management pack"

For a shop with 30 instances on a dozen hosts, would it make sense to use Grid Control EM 11g or EM 12c to deploy PSUs? Is one more reliable than the other? Our approach is opatch. And each quarter it takes much labor, time, and frustration to complete. We have an aging but functioning EM 10g Grid Control infrastructure. Never tried to use it for patching. But we have the diagnostic + tuning packs for our instances. So we should be licensed to use this technology for PSUs. When I've suggested we upgrade to EM 11g or EM 12c I typically get a response of the variety "we don't have time for that" (e.g. researching, testing, and then deploying EM 11g or 12c). My opinion? We don't have time *not* to do this. It's an investment in efficiency and I take the long view. It gives me no pleasure, and much pain, to repeatedly hear "we don't have time to learn X" when X is something that will improve efficiency, customer service, excellence, etc.

Sound familiar to anyone? If so, how have you played it short of finding another gig? I may try to track all staff hours involved with getting July PSUs completed to have some baseline metrics--everyone from the DBA team (reading about quirks and idiosyncracies of various PSUs on particular platforms/Oracle releases) to sysadmins to ops to managers, etc. In the time it takes to coordinate and execute the work using opatch, I can't help but wonder if we could have set-up at least EM 11g Grid Control in preparation for the next quarter. For now, I'm trying to socialize a January 1st, 2013 date to deploy EM 11g or EM 12c for patching and other goodness. You know, try to implement it, at least on some Production Floor dev and test boxes, when things have slowed down and most people (here in the U.S.) will be out of the office.

It may be that patching with EM 11g or EM 12c isn't patching nirvana. I'm not sure precisely how many staff hours (and frustration) it might save. Would love to hear personal stories here. But I'll settle for incremental improvement so we can move on to work higher up the value chain. If all my instances got moved to The Cloud, for instance, patching is a task I wouldn't miss.

Finally, are there cases in which folks would recommend sticking with opatch versus applying patches with Grid/Cloud Control? I imagine in very small shops using opatch would be fine. But in shops as large as the one I've described or larger--when DBAs are managing hundreds or thousands of instances--I can't imagine using opatch. Not unless it is fully scripted in some way.

If no one bites, and persists in saying "we don't have time for this", I'm going to make time on my home sandbox and work everything out there on my own time. Feels like The Right Thing To Do. Because an operational DBA group could always say "we don't have time for X." It's a bit like saying  "I don't have money to invest in a retirement plan." Decades pass and then you find you have to work forever...
