Compacting dbase via unattended scheduled task - DELAYED WRITE FAILED

Last Modified: 2012-08-14
I will explain what I am doing, then the error I keep recieiving.

I run a series of ACCESS 2000 macros at night and have scheduled them to run using a batch file.  The batch file uses the names of tasks that have been set up in windows task scheduler.


::--Start script.cmd---
@echo off
::Put your task names in order of execution here.
::Surround names with qoutes. Use space as delimiter.
set tasklist="ImportLVTCData" "Compact Sales" "Import Web Data" "Compact Webdata" "Import Website" "Compact Website" "Compact LVTC1_DATA"

::Main routine
for %%c in (%tasklist%) do (
schtasks /Run /TN %%c
call :loop %%c
goto :eof

::Task status checker
:: Pause. If you have sleep.exe
:: or other pause utility, put it
:: here instead of ping command
ping -n 5 > nul 2>&1

for /f "tokens=1,3,4 delims=," %%i in ('schtasks /QUERY /FO CSV /NH') do (
    If %%i==%1 (
        set var1=%%~j
        set var2=%%~k))
If "%var1:~0,-1%"=="Runnin" (
    echo Task %1 is running. Waiting...
    goto loop)
If "%var2:~0,-1%"=="Runnin" (
    echo Task %1 is running. Waiting...
    goto loop)
echo Task %1 ended.
goto :eof

::--End script.cmd---

Sometimes it works with no problems, but more often than not, I am getting the following error during the task IMPORTLVTCDATA.  

Unable to save all the data to db1.mdb.  All the data will be lost.  May be caused by a failure of hardware or network connection.

. . . when I try to open the dbase it tells me that I cannot open it because it is currently in use by someone else - even if I reboot - and it IS NOT being used by anyone else!!!

This particular task imports 8 *.dbf (dbase4) tables then compacts on close.  I believe that the error is occuring during the compact - this task used to ONLY import the tables followed by another task that would compact the dbase(via the /compact switch) & I used to always get that error during the compact task - now that I compact on close, the error seems to be happening after the importing of the tables.

ACCESS has added a table called: MSysCompactError - it has the following columns:

ErrorCode      ErrorDescription      ErrorRecid      ErrorTable
-1611      Could not find field 'Description'.            INVENTORY
-1611      Could not find field 'Description'.            MSysObjects

. . . under the 3rd column, it lists a row for each table & query in the dbase plus 6 rows with the "MSysObjects"????

The dbase that I am trying to compact is on a network drive (not local), but I am sure that nobody is using it at the time it is being compacted.  I am using XP pro - I recently switched from Win 98 & never had this problem.

Any thoughts on this would be greatly appreciated.
