A Docker container is a standardized, encapsulated environment that runs applications. [25] A container is managed using the Docker API or CLI. [22] A Docker image is a read-only template used to build containers. Images are used to store and ship applications. [22] A Docker service allows containers to be scaled across multiple Docker daemons.
Container clusters need to be managed. This includes functionality to create a cluster, to upgrade the software or repair it, balance the load between existing instances, scale by starting or stopping instances to adapt to the number of users, to log activities and monitor produced logs or the application itself by querying sensors.
The Jazelle instruction set is well documented as Java bytecode.However, ARM has not released details on the exact execution environment details; the documentation provided with Sun's HotSpot Java Virtual Machine goes as far as to state: "For the avoidance of doubt, distribution of products containing software code to exercise the BXJ instruction and enable the use of the ARM Jazelle ...
The kill command is a wrapper around the kill() system call, which sends signals to processes or process groups on the system, referenced by their numeric process IDs (PIDs) or process group IDs (PGIDs). kill is always provided as a standalone utility as defined by the POSIX standard.
push 1L (the number one with type long) onto the stack ldc 12 0001 0010 1: index → value push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack ldc_w 13 0001 0011 2: indexbyte1, indexbyte2 → value
Portable number: For most signals the corresponding signal number is implementation-defined. This column lists the numbers specified in the POSIX standard. [10] Actions explained: Terminate – Abnormal termination of the process. The process is terminated with all the consequences of _exit() except that the status made available to wait() and ...
The most common method of assigning numbers to lines is to assign every line a unique number, starting at 1 for the first line, and incrementing by 1 for each successive line. In the C programming language the line number of a source code line is one greater than the number of new-line characters read or introduced up to that point.
