If we lost adconfig.pl file?Can we able to run autoconfig.

[applvision@apps admin]$ cd $AD_TOP/bin
[applvision@apps bin]$ ls -tlrh adconfig.pl
-rwxr-xr-x 1 applvision applmgr 36K Nov  6  2008 adconfig.pl
[applvision@apps bin]$ mv adconfig.pl adconfig.pl_27sep2013
[applvision@apps bin]$ sh /apps/vision/inst/apps/vision_apps/admin/scripts/adautocfg.sh
Enter the APPS user password:
Can't open perl script "/apps/vision/apps/apps_st/appl/ad/12.0.0/bin/adconfig.pl": No such file or directory
[applvision@apps bin]$

When we run autoconfig using "adautocfg.sh" it calls adconfig.sh file and which in turn calls adconfig.pl script.
adconfig.pl is main script which start the autoconfig engine.If we lost adconfig.pl it not possible to run autoconfig.

Once we lost adconfig.pl file its not possible to re generate it.We have to copy it from other server.
