JPH04105128A - High speed command starting system by residence - Google Patents

Abstract

PURPOSE:To shorten the command starting time by selecting a specific command that is frequently used and making this command reside in a memory when a system is started. CONSTITUTION:A terminal 1 is provided, together with a command processor 2, a command residence means 3, a residence command name table 4, a residence command name table updating means 5, a command starting log collection means 6, the command starting log information 7, a loader 8, a disk file 9, a residence command lading part 10, and a non-residence command loading part 11. Then a command having a high starting frequency is kept resident n a memory when a system is started. Thus the commands which are frequently used are started at a high speed.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for quickly starting a command by making it resident.

[Conventional technology]

Conventionally, when a command in a computer system is started by specifying a command name from a command processor, a loader searches a disk file, finds the specified command, loads it into memory, and controls it. was passing it on.

[Problem to be solved by the invention]

In the conventional command startup method described above, the loader always searches for a disk file and, if found, loads it into memory, so the disadvantage is that it takes time to start each time even if the command is used very frequently. There is.

SUMMARY OF THE INVENTION An object of the present invention is to provide a high-speed command startup method by selecting a frequently used specific command and making it resident in memory at system startup, thereby reducing command startup time. It is.

[Means to solve the problem]

The high-speed command startup method using resident command of the present invention loads the corresponding command based on the resident command name list obtained from the disk file at system startup, makes it resident in memory, and associates its entry address with the resident command name. A command resident means registers a resident command name table, and when a command name is specified from the terminal, it refers to the resident command name table and if the corresponding command is in memory, it is activated as is, and if not, it is activated. a command processor that is started after being loaded by a loader; a command startup log collection unit that updates command startup log information that records the number of startups for each command that is started by the command processor; and resident command name table updating means for updating the resident command name table and storing the updated resident command name in the disk file.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In the embodiment of FIG. 1, terminal 1. Command processor 2. Command resident means 3. Resident command name table 4. Resident command name table update means 5, command startup log collection means 6. Command startup log information 7. Loader 8. Disk file 9. Resident command load section 10. It consists of a non-resident command load section 11.

FIG. 2 is an explanatory diagram showing the structure of the resident command name table 4, and FIGS. 3 to 5 respectively show the command resident means 3.
．． 2 is a flowchart showing the processing flow of the command processor 2 and the resident command name table updating means 5. FIG.

Next, the operation of this embodiment will be explained with reference to the drawings.

When the system is started up, the command resident means 3 is activated by the system. According to the procedure shown in FIG. 3, the command resident means 3 first reads and expands the information in the resident command name entry 41 of the resident command name table 4 from the disk file 9 in step 31. next,
In step 32, expanded resident command name entry 4
The loader 8 is started based on the command name of No. 1, and the command program is loaded into the resident command loading unit 10 on the memory. In step 33, the entry address is set as the resident command entry address entry 42 of the resident command name table 4. Store in parts. After storing the entry address, it is determined in step 34 whether processing has been completed for all command names in the resident command name table 4. If not completed, the same processing steps are repeated for the next command name stored in the resident command name entry 41, and when all command names are completed, the command resident processing is ended.

When a command name is specified from the terminal 1 during system operation, control is passed to the command processor 2.

According to the procedure shown in FIG. 4, the command processor 2 first searches for the resident command name entry 41 in the resident command name table 4 in step 21. As a result of the search, if it is determined in step 22 that the corresponding command does not exist (non-resident), the loader 8 is activated in step 23 to load the command program into the non-resident command loading section 11 of the memory.

If the command is determined to be resident, the entry address is read from the resident command entry address entry 42. Thereafter, in step 24, the command activation log collection means 6 is activated, and the activation number information for each command recorded in the command activation log information 7 is counted up. Then, in step 25, control is passed to the command program.

When the system is shut down, the resident command name table updating means 5 is activated by the system. The resident command name table updating means 5 performs step 5 according to the procedure shown in FIG.
1, the number of activations for each command in the command activation log information 7 is referred to, and the n highest number of activations are checked, and the resident command name entry 41 is updated in step 52. Thereafter, in step 53, only the updated resident command name entry 41 of the resident command name table 4 is saved on the disk file.

〔Effect of the invention〕

As described above in detail, the present invention has the advantage that frequently used commands can be started quickly by making them resident in memory. Further, by referring to the command activation log information, it is possible to follow changes in the system state and even if frequently used commands change.
