Retention of Variable Value when a script is called by different processes in parallel- Linux 2.6.9
Hi,

I have a generic FTP script which will be called by 28 different processes in parallel (through a GUI tool) may or may not be at the exact moment (there could be a delay of about a minute or so).

Code:
 
./FTP.ksh 1 (1 through 28)

This script after importing file from remote m/c inserts a record for that particular file in an Oracle table (see Fig 2). The "ID" column takes value from 1 ... 28. Column "SEQ" takes value from Oracle Sequence generator (so its unique). Column "TABLE_RECORD_COUNT" is inserted with '0'."Column "FILE_STATUS_FLAG" will have default value of 'A' (arrived) while inserting.

Code:
FILE_NAME|ID|SEQ|FILE_STATUS_FLAG|FILE_RECORD_COUNT|TABLE_RECORD_COUNT|CREATED_DATE|LAST_UPDATED_DATE|FILE_SIZE
r1_file1_<timestamp>.gz|1|1|A|899800|0|16-Mar-10|16-Mar-10|4000000
r1_file2_<timestamp>.gz|2|2|A|894700|0|16-Mar-10|16-Mar-10|187852398
r2_file1_<timestamp>.gz|3|3|A|799800|0|16-Mar-10|16-Mar-10|187852398
r2_file2_<timestamp>.gz|4|4|A|799720|0|16-Mar-10|16-Mar-10|187852398
r1_file1_<timestamp>.gz|1|5|A|899800|0|17-Mar-10|17-Mar-10|4000000
r1_file2_<timestamp>.gz|2|6|A|894700|0|17-Mar-10|17-Mar-10|187852398
r2_file1_<timestamp>.gz|3|7|A|799800|0|17-Mar-10|17-Mar-10|187852398
r2_file2_<timestamp>.gz|4|8|A|799720|0|17-Mar-10|17-Mar-10|187852398

Fig 2 (INSERT)

At the end of the process (which loads data from the file to a table) again a Unix script will be called which will update the record inserted by the FTP script.

Now the updating script some how should know which record to update? And then it will update the table with values as below:

Code:
FILE_NAME|ID|SEQ|FILE_STATUS_FLAG|FILE_RECORD_COUNT|TABLE_RECORD_COUNT|CREATED_DATE|LAST_UPDATED_DATE|FILE_SIZE
r1_file1_<timestamp>.gz|1|1|P|899800|899800|16-Mar-10|16-Mar-10|4000000
r1_file2_<timestamp>.gz|2|2|P|894700|894700|16-Mar-10|16-Mar-10|187852398
r2_file1_<timestamp>.gz|3|3|P|799800|799800|16-Mar-10|16-Mar-10|187852398
r2_file2_<timestamp>.gz|4|4|P|799720|799720|16-Mar-10|16-Mar-10|187852398
r1_file1_<timestamp>.gz|1|5|P|899800|899800|17-Mar-10|17-Mar-10|4000000
r1_file2_<timestamp>.gz|2|6|P|894700|894700|17-Mar-10|17-Mar-10|187852398
r2_file1_<timestamp>.gz|3|7|P|799800|799800|17-Mar-10|17-Mar-10|187852398
r2_file2_<timestamp>.gz|4|8|P|799720|799720|17-Mar-10|17-Mar-10|187852398

Fig 3 (UPDATE)

The script has updated column "FILE_STATUS_FLAG" to 'P' (processed) and column "TABLE_RECORD_COUNT" by executing "SELECT COUNT(1) FROM TABLE". Now I wonder if there's a way of remebering SEQ value till one process gets complete. Even if another process has kicked off the FTP script. Please suggest.
