Mongo -authenticationDatabase admin -u -p On the command line you see the result of the execution and possible log outputs. If mongo.exe is not available in the path of your command line, you find the shell in the bin directory in the installation directory of your MongoDB. Mongo.exe -authenticationDatabase admin -u -p Replace the placeholders in and execute the following command.To successfully execute a script, you need the database user and the name of the database from the effektif-onpremise.properties configuration file: The shell is already installed with most MongoDB installations and is available on the server on which MongoDB was installed. I think this is how Linux works, and a consistent viable design.To execute a JavaScript file for MongoDB, the Mongo Shell is required ( mongo/mongo.exe).

(I think this is right I've looked at a few bits of Linux kernel code but haven't really gotten my hands dirty experimenting with things. But this is irrelevant because Linux doesn't keep stuff on a task's kernel stack while user-space is running, except for a pointer to per-task stuff at the bottom of the region where the kernel can find it with SP & -16384. So even if there was some desire to re-enter the kernel with the stack as you left it, that would normally be at the TSS location anyway. (Context switches between asks actually happen in the kernel, switching kernel stacks to the formerly-sleeping task's kernel stack, so eventually returning to user-space means returning up the call-chain of whatever that task was doing in the kernel first).īTW, unless the kernel pushes a new CS:EIP / EFLAGS / SS:ESP for iret to pop, the stuff it pops will be the stuff pushed by hardware at the address specified in the TSS. Kernel state doesn't live on the kernel stack between entries into the kernel it's kept elsewhere in a process control block. There's no useful data on it, so the TSS can hold a fixed SS:SP value that points to the top of the virtual page allocated as the kernel stack for the current task. Once the kernel returns to user-space for a given task, it's done with that task's kernel stack until the next interrupt / exception. How is this kernel stack value set up, since they are not stored to TSS in step 2? Here it needs to find the kernel stack from ESP & SS in TSS. But from the manual, there is no change to TSS Resumes execution of the interrupted procedure.Restores the SS and ESP registers to their values prior to the interrupt or exception, resulting in a stack switch back to the stack of the interrupted procedure.Restores the CS and EIP registers to their values prior to the interrupt or exception.Begins execution of the handler procedure at the new privilege level.If the call is through an interrupt gate, clears the IF flag in the EFLAGS register.Loads the segment selector for the new code segment and the new instruction pointer (from the interrupt gate or trap gate) into the CS and EIP registers, respectively.Pushes an error code on the new stack (if appropriate).Pushes the temporarily saved SS, ESP, EFLAGS, CS, and EIP values for the interrupted procedure’s stack onto the new stack.Loads the segment selector and stack pointer for the new stack (that is, the stack for the privilege level being called) from the TSS into the SS and ESP registers and switches to the new stack.Temporarily saves (internally) the current contents of the SS, ESP, EFLAGS, CS, and EIP registers.If a stack switch does occur, the processor does the following: When I read Intel's X86 programmer's manual, see the following for interrupt & interrupt return with stack switching:
