Method and system for extracting log and trace buffers in the event of system crashes

A system for extracting data of a buffer after a failure of an operating system in a computing environment, wherein said buffer is a region of a volatile memory in which said data is stored prior to said failure, said system comprising:

• means for registering an application prior to said failure, said registering comprising means for identifying a buffer in which data resides, said data stored in said buffer by said application, said application being executed under said operating system;
• means for reserving said buffer, said reserving maintaining said data residing in said buffer as unchanged from an initiation of a reboot of said operating system responsive to said failure to a completion of said reboot, said reboot being a fast reboot;
• means for generating an in-memory file during said reboot, said in-memory file pointing to said data residing in said buffer, and said in-memory file being stored in said volatile memory and not in a persistent storage medium;
• and
• means for extracting said data via an instruction operating on said in-memory file, said instruction executed by said application after said completion of said reboot.

At least one program storage device readable by a machine, tangibly embodying at least one program of instructions executable by the machine to perform a method of extracting data of a buffer after a failure of an operating system in a computing environment, wherein said buffer is a region of a volatile memory in which said data is stored prior to said failure, said method comprising:

• registering an application prior to said failure, said registering comprising identifying a buffer in which data resides, said data stored in said buffer by said application, said application being executed under said operating system;
• reserving said buffer, said reserving maintaining said data residing in said buffer as unchanged from an initiation of a reboot of said operating system responsive to said failure to a completion of said reboot, said reboot being a fast reboot;
• generating an in-memory file during said reboot, said in-memory file pointing to said data residing in said buffer, and said in-memory file being stored in said volatile memory and not in a persistent storage medium;
• and
• extracting said data via an instruction operating on said in-memory file, said instruction executed by said application after said completion of said reboot.

A method for deploying computing infrastructure, comprising integrating computer-readable code into a computing system, wherein the code in combination with the computing system is capable of performing a process of extracting data of a buffer after a failure of an operating system in a computing environment, wherein said buffer is a region of a volatile memory in which said data is stored prior to said failure, said process comprising:

• registering an application prior to said failure, said registering comprising identifying a buffer in which data resides, said data stored in said buffer by said application, said application being executed under said operating system;
• reserving said buffer, said reserving maintaining said data residing in said buffer as unchanged from an initiation of a reboot of said operating system responsive to said failure to a completion of said reboot, said reboot being a fast reboot;
• generating an in-memory file during said reboot, said in-memory file pointing to said data residing in said buffer, and said in-memory file being stored in said volatile memory and not in a persistent storage medium;
• and
• extracting said data via an instruction operating on said in-memory file, said instruction executed by said application after said completion of said reboot.
