First time upgrading Oracle Apps Server. So not that familiar in this area.
1. Step 6.1.2 in Oracle Application Server Patch Set Notes it says <p>
If you are applying 10g Release 3 (10.1.3) Patch Set 5 (10.1.3.5.0) to a 10g Release 3 (10.1.3.0.0) Oracle home and your system uses Enterprise Javabeans 3.0 applications, then you must undeploy your applications before applying the patch </p>
When I try to start Application Server Control I get the following error, please advice <p>
./apps/tech_st/10.1.2/bin/emctl start iasconsole
./apps/tech_st/10.1.2/bin/emctl: line 336: cd: /d2/R12AB/ab/apps/FINVIS19/apps/tech_st/10.1.2/: No such file or directory

It seems like you are upgrading E-Business Suite . If thats the case its better post the problem in Ebiz forum. Also post the document id you are following, your app and db release, OS release. We do not deploy J2EE applications on Ebiz Tech Stack app server. So un-deployment should not be applicable here.
