The devicemapper driver uses block devices dedicated to Docker and operates atthe block level, rather than the file level. These devices can be extended byadding physical storage to your Docker host, and they perform better than usinga filesystem at the operating system (OS) level.
This host is running in loop-lvm mode, which is not supported on production systems. This is indicated by the fact that the Data loop file and a Metadata loop file are on files under /var/lib/docker/devicemapper. These are loopback-mounted sparse files. For production systems, see Configure direct-lvm mode for production.
Production hosts using the devicemapper storage driver must use direct-lvmmode. This mode uses block devices to create the thin pool. This is faster thanusing loopback devices, uses system resources more efficiently, and blockdevices can grow as needed. However, more setup is required than in loop-lvmmode.
Create two logical volumes named thinpool and thinpoolmeta using thelvcreate command. The last parameter specifies the amount of free spaceto allow for automatic expanding of the data or metadata if space runs low,as a temporary stop-gap. These are the recommended values.
Increase the size of the data file to 200 G using the truncate command,which is used to increase or decrease the size of a file. Note thatdecreasing the size is a destructive operation.
c. Calculate the total sectors of the thin pool using the second field of the output. The number is expressed in 512-k sectors. A 100G file has 209715200 512-k sectors. If you double this number to 200G, you get 419430400 512-k sectors.
To extend a direct-lvm thin pool, you need to first attach a new block deviceto the Docker host, and make note of the name assigned to it by the kernel. Inthis example, the new block device is /dev/xvdg.
The /var/lib/docker/devicemapper/metadata/ directory contains metadata aboutthe Devicemapper configuration itself and about each image and container layerthat exist. The devicemapper storage driver uses snapshots, and this metadatainclude information about those snapshots. These files are in JSON format.
The base device is the lowest-level object. This is the thin pool itself.You can examine it using docker info. It contains a filesystem. This basedevice is the starting point for every image and container layer. The basedevice is a Device Mapper implementation detail, rather than a Docker layer.
Each image layer is a snapshot of the layer below it. The lowest layer of eachimage is a snapshot of the base device that exists in the pool. When you run acontainer, it is a snapshot of the image the container is based on. The followingexample shows a Docker host with two running containers. The first is a ubuntucontainer and the second is a busybox container.
Data on a lost or stolen computer is vulnerable to unauthorized access, either by running a software-attack tool against it or by transferring the computer's hard disk to a different computer. BitLocker helps mitigate unauthorized data access by enhancing file and system protections. BitLocker also helps render data inaccessible when BitLocker-protected computers are decommissioned or recycled.

Pass an additional OVERRIDE_VIDEO_OUTPUT_DIR environment variable with absolute path to video directory on host machine. This is required because video recorder container, automatically created by Selenoid should save video to host machine video storage directory.
Selenoid can save session metadata to a separate JSON file. Main use case is to somehow post-process session logs, e.g. send them to map-reduce cluster. No additional configuration is needed to enable this feature. When enabled and -log-output-dir flag is set - Selenoid will automatically save JSON files /.json with the following content:
All the information on your WordPress site, such as post data, page data, meta information, plugin settings, login information, etc. is stored in your MySQL database. The only data not stored there is media content such as images and your theme/plugin/core files such as index.php, wp-login.php, etc.
Then take those new credentials and update your wp-config.php file. You will want to update the DB_USER and DB_PASSWORD values. You could also rerun the test file from earlier. This should then resolve your credentials issue. If not, you could still have the wrong hostname (DB_HOST). Some hosts use different values.
If you are a Kinsta user, checking your credentials against your wp-config.php file and the server is much easier! All you need to do is click on the info section of your site, and towards the bottom, you will see the database name, username, and password. By default, Kinsta uses localhost for the DB_HOST.
After running the repair of the database above, ensure that you remove the line of code you added to your wp-config.php file. Otherwise, anyone will be able to access the repair.php page. If you are running cPanel, you can also run a repair from within the MySQL databases screen.
How the session information is encoded. Use md5 for encryption using the md5 algorithm, or hex for hexadecimal encoding. If you encrypt the session data, a user with access to the file system cannot read the session contents. The default is md5.
The AEM integration with Adobe Analytics delivers configuration data in an analytics.sitecatalyst.js file in your website. The example dispatcher.any file that is provided with Dispatcher includes the following invalidation rule for this file:
The mode property specifies what file permissions are applied to new directories and files in the cache. This setting is restricted by the umask of the calling process. It is an octal number constructed from the sum of one or more of the following values:

pgbench is a simple program for running benchmark tests on PostgreSQL. It runs the same sequence of SQL commands over and over, possibly in multiple concurrent database sessions, and then calculates the average transaction rate (transactions per second). By default, pgbench tests a scenario that is loosely based on TPC-B, involving five SELECT, UPDATE, and INSERT commands per transaction. However, it is easy to test other cases by writing your own transaction script files. 153554b96e
