Whenever we clone Production to Dev, the s_login_page changes from /oa_servlets/AppsLogin to the old style /OA_HTML/ICXINDEX.htm.
This is not a bother as it redirects to the correct page, however it always bothered me. Using ICXINDEX.htm causes other problems as I learnt in a TAR with Oracle in 2006.
The context file is created from files in $COMMON_TOP/clone/context/apps, so I searched for the string ICXINDEX in all files in that directory:
$ cd $COMMON_TOP/clone/context/apps
$ grep ICXINDEX *
If you change the value of %s_login_page% variable to point to /
This would solve it temporarily. However where does adxmlctx.tmp come from ?
It comes from $AD_TOP/admin/template/adxmlctx.tmp
If you modify that you should be ok. I'll log an SR with Oracle to get them to fix this in their template.
