Mac Studio Recovery Mode

[Edelmar Easley]

Wehave a SQL Server Database Project (.sqlproj) in Visual Studio 2012 that we use as source control for our database schema. One of the cool things that it does is generate the SQL to update the schema when we release code.

Recently we changed our live database from "Simple" Recovery to "Full" Recovery. Everything was great until we tried to run our next deploy to dev and test. We don't want to change the recovery mode from Simple to Full on dev and test - there is no need for us to change it. However when we publish the database project it now wants to set it.

My current work around is to create a script in the Post-Deployment folder to work out which server I'm on and then set the recovery model back to simple if it's dev or test. This doesn't seem like the best solution.

Alter your VSTS Build definition to replace your 'Database Option:Recovery' with the desired state in your *.sqlproj before the msbuild step (I'm not sure you can change this per Release environment or based on the branch you're building on, so kinda ugly and unworkable to start with unless you have a separate build definition per environment):

Modify your VSTS Release to use "SQL Server Database Deploy" AND specify a "Publish Profile". I think the "Deploy database properties" option in the profile is equivalent to "Script Database Options" but I've not tested it because 2 was a reasonable solution for me. One could pre-setup the different profiles before build time or attempt to change a master profile with variables for each Release environment. I really didn't want to complicate my life with this...

So in the end I chose option (2) above and tested with and without the /p:ScriptDatabaseOptions=false setting. It worked as expected. Choosing option (2) means that you'll need to setup your environment databases ahead of time. We use a Recovery mode of SIMPLE in our non-Prod environments and FULL in our Prod environment. To verify either open up the database options in MSSQL Mgt Studio or view the SQL Server Logs to see if a message like so appeared:

If I needed to be able to stand up new databases as part of my release process then I may have to venture into the realm of option 3. If that is where you're at, then good luck and let us know what you had to do to make it work.

This codespace is currently running in recovery mode due to a container error. Review the creation logs, update your devcontainer configuration as needed, and run the "Rebuild Container" command to retry.

A recovery model is a database property that controls how transactions are logged, whether the transaction log requires (and allows) backing up, and what kinds of restore operations are available. Three recovery models exist: simple, full, and bulk-logged. Typically, a database uses the full recovery model or simple recovery model. A database can be switched to another recovery model at any time. The model database sets the default recovery model of new databases.

Point-in-time recovery isn't possible with bulk-logged model. Running transactions under the bulk-logged recovery model that require a transaction log restore, can expose them to data loss. To maximize data recoverability in a disaster-recovery scenario, switch to the bulk-logged recovery model only under the following conditions:

Copy and paste the following example into the query window and select Execute. This example shows how to query the sys.databases catalog view to learn the recovery model of the model database.

Copy and paste the following example into the query window and select Execute. This example shows how to change the recovery model in the model database to FULL by using the SET RECOVERY option of the ALTER DATABASE statement.

In this wiki, we will show you how to flash Jetpack OS to reComputer J1020. Since the carrier board of it is designed like the offical NVIDIA Nano Developer Carrier Board, we can flash the JetPack in two ways.

We can use NVIDIA SDK Manager Linux Software or we can directly use the NVIDIA Linux Driver Package via Linux command line to flash JetPack OS into the reComputer J1020. For the beginners to NVIDIA Jetson, we highly recommand NVIDIA SDK Manager.

Step 4. Under the command line window of the host computer, enter the command lsusb. When the returned content has the ID 0955:7f21 NVidia Corp. in it, it means that the reComputer is in the force recovery mode and we can proceed to the subsequent operations.

Next we will go through the tutorial about installing the system via NVIDIA SDK Manager. The an NVIDIA SDK Manager all-in-one tool that bundles developer software and provides an end-to-end development environment setup solution for NVIDIA SDKs. Thus, it is recommanded for the beginners.

After logging in, you will be taken to the first screen where the first step of installing. Since we have already connected the reComputer J1020, there will be a window pop up to let you select the hardware device.

!!!TipWhen choosing which components to install, you may want to keep an eye on the capacity used. The built-in eMMC size is only 16GB, please allocate and use this space wisely according to your actual needs.

If you want SDK Manager to download all the files to a location other than the default path, go to the Download & Install Options located at the bottom of the screen, then select the path you wish to use.

After a while, we will be asked to set up the new system for our reComputer. Since we manually force into recovery mode, we select Manual setup: set the target to Force Recovery Mode via manual operations here. Meanwhile, we choose the default Pre-Config.

After a moment, you will be able to see a new window pop up in the NVIDIA SDK Manager, prompting you that you need to connect to your device via IP address. It means the system has been alreadly installed and the components installing will be proceeded.

In this case, we can pull out the jumper and restart the reComputer. Then we need to connect the reComputer to a monitor via HDMI, enter the password you entered in step 4, and log in to the main interface.

Go back to the Linux host PC and enter the IP address you just obtained. NVIDIA SDK Manager will try to connect to the Jetson device and proceed to complete the installation of the next SDK components.

Once you find the proper version, click to go to the downloaded page. Find and click the "L4T Driver Package (BSP)" and "Sample Root Filesystem" to download the driver files. The names of the files are like Tegra_Linux_Sample-Root-Filesystem_Rxx.x.x_aarch64.tbz2 and Jetson-210_Linux_Rxx.x.x_aarch64.tbz2.

On the Linux host PC, we should find a folder and store the package files we download before. Then open a command line window(Terminal) at the folder and use the command line below to unzip the files and assemble the rootfs:

a. From Flashing to eMMC with SDK Manager -- Step 3, use the Repair/Uninstall button to get to the Manage NVIDIA SDKs page. If needed, expand the SDK that has the "Broken" status, then click Repair for the relevant part (Host or Target).

If you encounter the error shown below in Flashing to eMMC with command-line -- Step 2, you probably did not succeed in getting the Carrier Board into force recovery mode. Please pay special attention, do not enter force recovery mode with the Carrier Board powered on, as this is not valid.

If you can't get into the system in Flashing to eMMC with command-line -- Step 3 and are stuck on the boot up display command line, you probably did not exit force recovery mode. Likewise, it is not valid for you to unplug the jumper to exit force recovery mode while the Carrier Board is powered up, this all needs to be done while you are powered down.

I tried adb reboot recovery, adb reboot bootloader, adb shell reboot recovery, etc. All of these commands print no output, and hang indefinitely while the emulator shows no response. (Side note: adb devices shows emulator-5554, as expected.)

I noted that issuing a shutdown command through the UI also hangs indefinitely, so I'm thinking maybe rebooting is simply not an option for the emulator. Is there a different way that I can boot an Android virtual device into recovery mode?

If your goal is to install Google Apps in the emulator, then you need to follow a completely different proceedure then the one telling you to reboot into recovery. Truth is, the emulators do not have a recovery partition, so there's no such thing as recovery mode for an emulator.

Search for procedures that are specific to the problem of getting Google Apps running in the emulator. I've done it before, but I can tell you it's a pain and there's no generic way to explain it without knowing the specifics of your setup (i.e., SDK version, x86 vs. ARM, etc.). Even then, it may not be possible.

If there's not a compelling reason forcing you to use the emulators, consider trying a virtual machine solution like Genymotion instead of the emulator. VMs are way faster than the SDK emulators and for most there are clear procedures available for installing Google Apps. Genymotion in particular has instructions for doing so. Genymotion also integrates with Android Studio/Eclipse and supports the debug bridge (adb). See genymotion.com to download.
