Abstract

It discloses an improved adapter tool, which provides optimal interface between message queues ("MQ") and databases ("DB") and also provides a developer with efficient interpreter script language. In order to connect MQ and DB, the present adapter performs the following steps. 1. Generation of Script Lists(DEFINE and COMMAND lists) (i) It reads the I/F script file that the developer has made using the interpreter script language. (ii)It generates a DEFINE list by using configuration sentences for I/F header information read from the script file. (iii)It also generates a COMMAND list by using command sentences for I/F execution read from the script file. (iv)If the sentence from the script file is sub script macro command, it repeatedly performs the above three steps to generate DEFINE and COMMANS lists for the sub script macro command. 2. Parsing the COMMAND List (i) It parses the COMMAND list and checks for command error. (ii) It generates GOTO label list, if there is found a label command (i.e., GOTO sentence) in the COMMAND list. (iii) It appoints the execution location for GOTO sentence. (iv) In order to enhance the execution performance, it connects MQ and DB before executing the COMMAND list. MQ and DB are connected until the termination of the adapter. 3. Execution (i) It waits for Send/Receive request (ii) When it receives Send/Receive request, the COMMAND list is executed line by line. (iii) In order to record the process trace information, the log message of the executed COMMAND list is registered on the log information.

Adapter Tool which runs on multi-platform

  It discloses an improved adapter tool, which provides optimal
interface between message queues ("MQ") and databases ("DB") and
also provides a developer with efficient interpreter script
language. In order to connect MQ and DB, the present adapter
performs the following steps.

1. Generation of Script Lists(DEFINE and COMMAND lists)
(i) It reads the I/F script file that the developer has made
using the interpreter script language.
(ii)It generates a DEFINE list by using configuration sentences
for I/F header information read from the script file.
(iii)It also generates a COMMAND list by using command
sentences for I/F execution read from the script file.
(iv)If the sentence from the script file is sub script macro
command, it repeatedly performs the above three steps to
generate DEFINE and COMMANS lists for the sub script macro
command.

2. Parsing the COMMAND List
(i) It parses the COMMAND list and checks for command error.
(ii) It generates GOTO label list, if there is found a label
command (i.e., GOTO sentence) in the COMMAND list.
(iii) It appoints the execution location for GOTO sentence.
(iv) In order to enhance the execution performance, it connects
MQ and DB before executing the COMMAND list. MQ and DB are
connected until the termination of the adapter.

3. Execution
(i) It waits for Send/Receive request
(ii) When it receives Send/Receive request, the COMMAND
list is executed line by line.
(iii) In order to record the process trace informat...
