1- Why the  Platform is showing linux 32 as this instance is running on a Linux 64 bit server   ?
2 - The same value is showing for Database report  " Platform linux 32 "  as this instance is running on 1 Linux 64 bit server ?  Both DB and Apps running in the same server.
         a) I think Apps doesn't have 64 bit version, but I have installed DB 64 bit only.
3 - To upgrade the java, Do I need to follow the both Notes ID as per my TXK output ?             
Deploying  Sun JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release  12 (Note 393931.1)
Upgrading OracleAS 10g Forms and Reports in Oracle E-Business Suite Release 12 (Note 437878.1)
4 - Lots of patches are not applied as per the note 437878.1
5 - Is it mandatory to upgrade JDK as well as per the note  " Using JDK 7.0 Latest Update with Oracle E-Business Suite Release 12.0 and 12.1 ( Doc ID 1467892.1) ?
6 - Please suggest me on all queries and the order which I have to follow
Please give me a clear picture .
Thanks,
Sal

   I wan to do everything in one project.so I followed below steps. But I stuck in one place:
1 - Upgrading OracleAS 10g Forms and Reports in Oracle E-Business Suite Release 12 and done successfully
2 - Deploying JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release 12 (Doc ID 393931.1):
      Upgraded JRE plugin successfully
3 -  Upgrade JDK to 6
          JDK to 6 [ 1.6_51]
          Using Latest Java 6.0 Update With Oracle E-Business Suite Release 12 (Doc ID 455492.1)
        Successfully completed.
4 - Upgrade OracleAS 10g to 10.1.3.5
      Note:Upgrading to the Latest OracleAS 10g 10.1.3.x Patch Set in Oracle E-Business Suite Release 12 (Doc ID 454811.1)
      Successfully completed
5 -  Upgrade JDK to 7u25 on both both 10.1.2 and 10.1.3 Homes
     JDK to 7 [ 1.7.25]
     Note:Using JDK 7.0 Latest Update with Oracle E-Business Suite Release 12.0 and 12.1 (Doc ID 1467892.1)
     While applying patch - 14703419, I got conflict patch with 12848228 which I hv applied during the JDK upgrade to 6. So I hv rolledback the patch 12848228 and applied the patch 14703419
    While running below
#   cd $ORACLE_HOME/forms/lib
#   make -f ins_forms.mk sharedlib install
I got below error:
