How is the environment?

In my environment i have five servers, one for backup, two for test purposes and two more for production.

In Production Environment(PE), one of sever has installed oracle database(DB) and the other has Oracle Application Server(OAS). Test Environment(TE) has a copy of production environment and it's used for new developments, testing them, news products installation. When new developments has been checked then pass from TE to PE.

 In TE, i have installed two different eBS instances. One of them called  desa and the other called test.

Desa and test instance has differents folder in differents machines:
- In db machine(called ioversondb2):
              /u02/oracle/iosadesadata
        /u02/oracle/iosatestdata
with this datafiles:
archive01.dbf                a_ref02.dbf                      a_txn_ind04.dbf                 olap.dbf               a_archive02.dbf            a_summ01.dbf          a_txn_ind05.dbf            owad01.dbf                     a_int01.dbf                        a_tools01.dbf        cntrl03.dbf            portal01.dbf                a_media01.dbf           a_txn_data01.dbf                       ctxd01.dbf              temp01.dbf                      a_nolog01.dbf                     a_txn_data02.dbf         discoverer01.dbf           undo01.dbf                             a_queue01.dbf           a_txn_data03.dbf             log01b.dbf
undo02.dbf                 a_queue02.dbf             a_txn_ind01.dbf                       log02b.dbf               user_data01.dbf                archive a_txn_ind02.dbf log03b.dbf                  user_idx01.dbf            a_ref01.dbf                               a_txn_ind03.dbf        odm.dbf                         xx_data01.dbf          

- In oas machine(called ioversonas2):
 /u02/oracle/iosatestappl
/u02/oracle/iosatestcomn
/u02/oracle/iosatestora

/u02/oracle/iosadesaappl
/u02/oracle/iosadesacomn
/u02/oracle/iosadesaorap



Depending on login user: appltest or applmgr, then start .bash_profile within:
/u02/oracle/iosatestappl/APPSIOSATEST_ioversonas2.env for appltest

/u02/oracle/iosatestappl/APPSIOSADESA_ioversonas2.env for applmgr

inside APPSIOSATEST_ioversonas2.env appears very important path:

# APPL_TOP is the top-level directory for Oracle Applications.
APPL_TOP="/u02/oracle/iosatestappl"
