To leverage the power of multi-threading with a Domino server tasks, you have to load the same task several times. But then you have to divide the work between each of them.

Example: I would like to do a quick Fixup on 200 mail databases. That will take 4 less time if I load 4 Fixup tasks, and affect a quarter of the databases to each of them. The problem has always been to build these 4 databases lists in indirect files (IND).

This simple script will do the job in one second. 

The script is written with Windows PowerShell, so restricted to Windows platform, but not old Windows server.

1. Just open a Windows PowerShell command.
   You may need to open it in ADMIN mode, otherwise you won't have enough rights to write the files.
2. Look at the script and correct the parameters
3. Paste the script and run.
4. Done. The IND files are ready for use in the Data directory.

The script:

$DATA = "d:\ibm\domino\data";$DIRECTORY = "mail";$GROUPSNB = 4 ;$files = Get-ChildItem "$DATA\$directory\*.nsf" -Name; $count = $files.count; $nb = [math]::ceiling($count / $GROUPSNB) ;$groupi = 1 ;$results = @(); $i = 0 ;foreach ($filename in $files){$results += "$directory\$filename";$i += 1 ;if ( $i -eq $nb ) { $results | Out-File "$DATA\$DIRECTORY$groupi.ind" -Encoding "default"; $i = 0 ; $groupi += 1 ; $results = @();};}; if ( $results -ne "" ) { $results | Out-File "$DATA\$DIRECTORY$groupi.ind"  -Encoding "default"; };  Write-Host "succeed: $groupi files have been created, listing $count databases." ; Write-Host "The files are in the directory: $DATA, they are named '$DIRECTORY`X.ind' ,  where X is from 1 to $GROUPSNB." ;

Use the .IND files

The IND files are waiting for you in the Domino DATA Directory, you can just call:

load fixup mail1.ind
