Sreenivash, Is backup an option in your case? If not you can try to use the following command: adrelink.sh force=y "ad adpatch" (exact syntax is abailable in Oracle Applications Maintenance Utilities book). The third option for you is to reinstall everything as if you don't have a backup this environment is not that important for your business ;) Jurijs On 7/27/07, k srinivas <k.sridba@xxxxxxxxx> wrote: > Hi DBAs, > > I have lost my adpatch executable.... > But I have to apply the patch...How to go about it.... > Anyway to get back???How to compile again? > > Thanks > Sreenivash.. > -- Yury +371 29268222 (+2 GMT) ============================================ http://otn.oracle.com/ocm/jvelikanovs.html
