Apache httpd services fail to start

R12 Apache server does not start. But the log file reports exiting status 0, which means normal.

Error
   --> Process (index=1,uid=41488097,pid=14132)
   failed to start a managed process after the maximum retry limit
   Log:
   /u02/app/EBSPROD/inst/apps/
<CONTEXT name>/logs/ora/10.1.3/opmn/HTTP_Server~1.log
   10/26/2014-10:04:39 : : adapcctl.sh: existing with status 0

 
HTTP_Server~1.log file does not give any useful information as well:
   14/10/26 10:04:39 Start process
   --------
   /u02/app/EBSPROD/inst/apps/
<CONTEXT name>/ora/10.1.3/Apache/Apache/bin/apachectl startssl: execing httpd


After deleted httpd.pid file in $INST_TOP/pids/10.1.3/Apache and added below debug options to httpd.conf file in $ORA_CONFIG_HOME/10.1.3/Apache/Apache/conf, "adapcctl.sh start" can start the httpd services. See Doc ID 422419.1 on how to enable debug logs.

LogLevel debug
OraLogMode oracle
OraLogSeverity TRACE:32
OraLogDir /u02/app/EBSPROD/inst/apps/<CONTEXT name>/logs/ora/10.1.3/Apache/oracle
 
But, The real fix seems to delete Apache folder under $LOG_HOME/ora/10.1.3 with all httpd log files, and then re-create it (and sub-folder oracle). I believe the cause was some log file exceeded 2GB limit in size.

Troubleshooting:

Logs for troubleshooting on startup:
$LOG_HOME/ora/10.1.3/Apache
$LOG_HOME/ora/10.1.3/opmn/     <= Check file HTTP_Server~1.log here if Apache does not start & no logs
$LOG_HOME/ora/10.1.3/j2ee/oacore/oacore_default_group_1/application.log      <= Notes: For example, this file got 8GB in size due to all 10.1.3.5.0 Container error entries (bug 10126440 ? )
$LOG_HOME/ora/10.1.3/j2ee/forms/forms_default_group_1/application.log

Other files can be checked with egrep -i 'fail|error' to see if any issues, when getting "Page not found":
$LOG_HOME/ora/10.1.3/opmn/oacore_default_group_1/oacorestd.err
$LOG_HOME/appl/rgf/javacache.log   (Java Object Cache (JOC) log, $APPLRGF)

- start APACHE by adapcctl.sh start
Make sure below lines do not give back any error:
./adapcctl.sh status
./adalnctl.sh status
If Apache is up and running with enabled ssl, below URL shall work
https://siteName.domian.com:ssl_port
siteName.domain.com can be replaced by its DNS ip address for troubleshooting (with possible "Certificate error" because the certs file is issued for the original site URL).
By this time, the re-direction to login page will not work because it needs oacore process running.

- start OACORE process (in 10.1.3 Oracle_Home) by adoacorectl.sh start
If the login page is unavailable immediately, check the opmn log first
$LOG_HOME/ora/10.1.3/opmn/default_group~oacore~default_group~1.log
If the login page gets internal errors or hangs, but below URLs work (in R12):
https://ip_address:ssl_port/OA_HTML/ServletPing
https://ip_address:ssl_port/OA_HTML/jsp/fnd/aoljtest.jsp   (it may not be configured in some sites)
https://siteName.domian.com:ssl_port/OA_HTML/jsp/fnd/aoljtest.jsp    -- bring up a test HTML form
check log files in $LOG_HOME/ora/10.1.3/j2ee/oacore/oacore_default_group_1 to get the real error.

-start FORMS process by adformsctl.sh start
After forms services are running, you shall be able to open forms by JRE popup. If forms does not open, check logs in $LOG_HOME/ora/10.1.3/j2ee/forms/forms_default_group_1 for any error.

- start OAFM OC4J by adoafmctl.sh start

If Apache is running on a server with IP 188.xx.67.77, TELNET on port s_webport (8020) returns below message in my R12.1 environment:
$ telnet 188.xx.67.77 8020
Trying...
Connected to 188.xx.67.77.
Escape character is '^]'.
GET
  <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
  <HTML><HEAD>
  <TITLE>400 Bad Request</TITLE>
  </HEAD><BODY>
  <H1>Bad Request</H1>
  Your browser sent a request that this server could not understand.<P>
  invalid request-URI <P>
  </BODY></HTML>
  Connection closed.

But "$ telnet 188.xx.67.77 4463" and GET return only "Connection closed." (for unknown reason). 4463 is the ssl_prot in the ssl-enabled configuration.

Most of times, Apache works fine. The problem may come from company Security policy change, fire wall or F5 network settings. All you need is to provide evidence as proof.

NOTE1: after using "adapcctl.sh start" to start Apache services, do not use "adapcctl.sh stop" to stop httpd services, which may leave file httpd.pid on the file system and leave opmn processes still running. Instead, Use "adopmnctl.sh stopall" to stop opmn processes and httpd processes.

NOTE2: All Apaches logs and opmn logs  (or log directories) can be deleted safely, including
    $LOG_HOME/appl/admin/log/adapcctl.text
    $LOG_HOME/ora/10.1.3/opmn/HTTP_Server~1.log
See Doc ID 1964851.1 to clean the logs and enable debug.

NOTE3: If a port defined for Apache is not available, Apache will not start. One day, "adstrtal.sh" gave a similar message above. After added debug options to Apache conf file, I found the problem "make_sock: could not bind to port 4482". Usually profile option APPS_SERVLET_AGENT has the site URL (name and port).

Trun on trace in EBS forms and Forms Node

EBS R12.1 has different ways to trace a user's session. Usually, apps tracing will help address issues on performance.

1. Trace a concurrent program with database .trc file

1) As System Administrator, go to Concurrent-> programs -> Define, and query program PROGRAM_NAME ie ARRGTA, or RAXTRX

2) Enable (or make sure) the check box called 'Enable Trace' and save

3) Before starting trace, make sure the following DB parameters are set:

MAX_DUMP_FILE_SIZE = UNLIMITED
TIMED_STATISTICS = TRUE
STATISTICS_LEVEL = ALL

If they are not set as above, run the following as SYS:

SQL> alter system set MAX_DUMP_FILE_SIZE=UNLIMITED;
SQL> alter system set TIMED_STATISTICS=TRUE;
SQL> alter system set STATISTICS_LEVEL=ALL;

4) Ask the user to rerun the report reproducing the issue

5) After the process finishes, run tkprof for the trace file with sort=exeela,prsela,fchela and
explain=<apps owner>/<apps password>. Example:
tkprof <sourcefile> <outputfile> sys=no explain=apps/<pw> sort=exeela,prsela,fchela

Please make sure the process already finished. If the process has not finished the rows column in tkprof will be all zeros and useless. Be sure to use the TKPROF under the RDBMS Oracle Home /bin directory. The TKPROF under the Applications Oracle Home will not yield accurate results.

2.  Oracle Support steps to trace just one session (when trace can not be turned on on a program) using SQL code.

1) Make sure trace is NOT enabled for any of the concurrent programs we will be running:
System Administrator > Concurrent > Programs > Define
Query the program ARRGTA
Make sure trace is DISABLED (It is important trace is disabled for the program so it does not interfere with the rest of the steps)

2) Create the following Procedure as database user APPS:

CREATE OR REPLACE PROCEDURE cp_level12_trace_util AS
req_id number:=fnd_global.conc_request_id;
prog_id number:=fnd_global.conc_program_id;
appl_id number:=fnd_global.RESP_APPL_ID;
prog_name varchar2(128);
trc_label varchar2(128);

BEGIN

if req_id > 0 then
select max(concurrent_program_name) into prog_name
from fnd_concurrent_programs
where concurrent_program_id=prog_id
and application_id=appl_id;

trc_label:='CP_'||prog_name||'_REQ_'||req_id;

FND_CTL.FND_SESS_CTL(''
,''
,''
,'TRUE'
,''
,'ALTER SESSION SET MAX_DUMP_FILE_SIZE=UNLIMITED');

FND_CTL.FND_SESS_CTL(''
,''
,''
,'TRUE'
,''
,'ALTER SESSION SET TIMED_STATISTICS=TRUE');

FND_CTL.FND_SESS_CTL(''
,''
,''
,'TRUE'
,''
,'ALTER SESSION SET STATISTICS_LEVEL=ALL');


FND_CTL.FND_SESS_CTL(''
, ''
, ''
, 'TRUE'
, ''
, 'ALTER SESSION SET TRACEFILE_IDENTIFIER='||''''
|| trc_label
|| ''''
|| ' EVENTS ='
|| ''''
|| ' 10046 TRACE NAME CONTEXT FOREVER, LEVEL 12 '
|| '''');

end if;
END;
/

3) Set the following profile option at user level, only for the user who reproduces the issue:

Profile option: Initialization SQL Statement - Custom
Value: begin cp_level12_trace_util; end;

NOTES: Be careful, as sometimes it may block user from login, and also see FND_INIT_SQL may cause error.

4) Run the concurrent request by the user, and upload all trace files, which have the request_id in their name (It will have something like CP_PROGNAME_REQ_999999, where PROGNAME is the short name of the program, and 999999 is the request id). If Trace files are too big, do not upload them for now

5) Run tkprof for the above trace files, and upload the output:
tkprof <trace file> <output file> sort=exeela,prsela,fchela explain=apps/<password>

Make sure the process already finished (if it hangs, please leave it running for a few hours before canceling). If the process has not finished the rows column in tkprof will be all zeros.

6) Upload also the log files for the concurrent requests

7) Do not forget to set the profile option “Initialization SQL Statement – Custom” back to BLANK afterwards.

3.  Trace EBS Forms session

1) Change Profile option Utilities:Diagnostics to "Yes" at user level
2) Help --> Diagnostics --> Trace --> to choose a tracing level. Then, a popup box will tell where the trace file .trc is saved.

4.  Find which node an EBS R12 session is connecting to

1) Change Profile option FND: Diagnostics to "Yes" at user level
2) Help -> About Oracle Applications (below section will tell which form node you have connected):
----------------------------------------
Forms Server
----------------------------------------
Oracle Forms Version : 10.1.2.3.0
Application Object Library : 12.0.0
Machine : node_name.domain.COM

NOTES:

- Turn "FND: Diagnostics" profile to Yes at user level will also add "About this Page" to EBS Homepage's left bottom after login and add "Diagnostics" on the right top of OA Framework pages. Clean the cache if they do not show up immediately after re-login.
- This profile option is different from turning "Utilities:Diagnostics" to Yes, which enables tracing on sub-menus of Help on GUI forms.
- I found that even "FND: Diagnostics" profile is set to No, "About this Page" may still shows up. That could be controlled by other things, such as other profile options for Personalization:

Personalize Self-Service Defn = YES
FND: Personalization Region Link Enabled = YES
Disable Self-Service Personal = NO (Only at Site)

Compile Oracle EBS forms and/or libraries

1. Use below steps as Applmgr to compile one R12 form in $CUSTOM_TOP/forms/US directory. Note frmcmp_batch.sh shall exist in $ORACLE_HOME/bin.

$ export FORMS_PATH=$FORMS_PATH:$AU_TOP/forms/US:$AU_TOP/resource:$CUSTOM_TOP/forms/US
$ cd $CUSTOM_TOP/forms/US
$ mv FORM_NAME.fmx FORM_NAME.fmx_BK (or delete it)
$ chmod 664 FORM_NAME.fmb (to make it -rw-rw-r--. This step seems optional).

$ frmcmp_batch.sh module=FORM_NAME.fmb userid=apps/XXXpwd output_file=FORM_NAME.fmx module_type=form compile_all=yes

If it works, it shall say "Created form file FORM_NAME.fmx". And new time stamp for two files FORM_NAME.fmb and FORM_NAME.fmx.

2. To compile only library (.pll) files, env variable $FORMS_PATH is not needed. Go to $AU_TOP/resources and run the command:

$ cd $AU_TOP/resource
$ frmcmp_batch.sh module=FORM_NAME.pll userid=apps/XXXpwd module_type=library compile_all=special batch=yes

After it completes, new timestamp will be on FORM_NAME.pll and FORM_NAME.plx without doing anything on .fmb and .fmx files (in $CUSTOM_TOP/forms/US if it is a custom form). The file size on FORM_NAME.pll may become bigger. Use command to check and compare contents:

$ adident Header $AU_TOP/resource/FORM_NAME.pll 

Notes:
(1). If option "batch=yes" is used, progress and error messages will not echo out on the screen when the commend runs. But they will be written to .err file in current directory.
(2). If it gets ORA-12154 error in R12, the workaround is to modify $TNS_ADMIN variable in frmcmp_batch.sh (Doc ID 431324.1).
export TNS_ADMIN=${TNS_ADMIN:-$ORACLE_HOME/network/admin}
(3). For a non-Applmgr user to compile a R12 form, it is necessary to change permission on a set of files (Doc ID 561334.1). Make sure ORACLE_HOME points to 10.1.2 location.
chmod +rx $ORACLE_HOME
chmod +rx $ORACLE_HOME/bin
chmod +rx $ORACLE_HOME/bin/frm*
chmod -R +rx $ORACLE_HOME/lib
chmod +rx $ORACLE_HOME/forms
chmod -R +rx $ORACLE_HOME/forms/mesg
chmod -R +rx $ORACLE_HOME/forms/admin
chmod -R +rx $ORACLE_HOME/oracore
chmod +rx $ORACLE_HOME/nls
chmod -R +rx $ORACLE_HOME/nls/data
chmod +rx $ORACLE_HOME/rdbms
chmod -R +rx $ORACLE_HOME/rdbms/mesg
chmod +rx $ORACLE_HOME/ldap
chmod -R +rx $ORACLE_HOME/ldap/mesg
chmod -R +rx $ORACLE_HOME/ldap/admin
chmod +rx $ORACLE_HOME/network
chmod -R +rx $ORACLE_HOME/network/admin
chmod -R +rx $ORACLE_HOME/jre
chmod -R +rx $ORACLE_HOME/procbuilder

(also go to $CUSTOM_TOP/forms/US, and give 666 to .fmx and .fmb files so that user can re-create the form files.) 
Note: after above grants, sqlplus is still not available to other users but form compile shall work.

3. Use ADADMIN to compile (or re-generate) multiple forms. The steps are documented in very good document: How To Regenerate Forms Library Files Using "adadmin" (11i & R12) (Doc ID 141118.1)
A) Select the "1. Generate Applications Files menu" option.
B) Then select the "2. Generate forms files" option.
C) Choose the number of workers (default is the # of CPUs in the server).
D) Enter "yes" to regenerate PL/SQL library files (.pll extension)
E) Enter "yes" to regenerate Forms Menu files (.mmb -> .mmx extension)
F) Enter "yes" to regenerate Forms Executable files (.fmb->.fmx extension)
G) Enter the list of products, by short name as they are listed in "$APPL_TOP/" (all OR ont, po, fnd, ar, gl)
H) Enter "No" to generate specific files for each product. If you like to generate specific files for each product, you may answer "Yes" here and a list of files will be displayed
I) Enter "all" to generate all the previously selected items for all languages, or only some of the installed languages.
J) Shows your default and/or selected languages
K) Enter "yes" if the languages selected are the desired languages

yes on F) will give new timestamp on .fmx files. After answered yes on D), some .plx files get new timestamp, but no .pll files get new timestamp.  I used adadmin to compile all forms in an instance and got one error:

The following Oracle Forms objects did not generate successfully:
ap      forms/US        APXWCARD.fmx

An error occurred while generating Oracle Forms objects.
Continue as if it were successful [No] :


adadmin log does not give much details on the error. So, I ran the command to compile this form individually:

$ cd $AP_TOP/forms/US
$ mv APXWCARD.fmx APXWCARD.fmx_BK_04292015
$ export FORMS_PATH=$FORMS_PATH:$AU_TOP/forms/US:$AU_TOP/resource:$AP_TOP/forms/US

$ frmcmp_batch.sh module=$AU_TOP/forms/US/APXWCARD.fmb userid=apps/APPS_PWD output_file=APXWCARD.fmx module_type=form compile_all=yes

FRM-30064: Unable to parse statement select distinct full_name, employee_number, date_of_birth, pa.person_id
from per_all_people_f pap,
financials_system_parameters fsp,
per_assignments_f pa
where (trunc(sysdate) between pap.effective_start_date and pap.effective_end_date)
and (trunc(sysdate) between pa.effective_start_date and pa.effective_end_date)
and pap.business_group_id = fsp.business_group_id
and pa.business_group_id = fsp.business_group_id
and pap.person_id = pa.person_id
and pa.assignment_type = 'E'
order by upper(full_name).
ORA-01791: not a SELECTed expression
Record Group FULL_NAME
Form: APXWCARD

FRM-30085: Unable to adjust form for output.
Form not created

To fix the problem, check the file version:
$ strings $AU_TOP/forms/US/APXWCARD.fmb | grep '$Header'
FDRCSID('$Header: APPSTAND.fmb 120.6.12010000.6 2010/03/10 12:58  dbowles ship     $');
FDRCSID('$Header: APXWCARD.fmb 120.16.12010000.14 2010/02/22 22:27  meesubra ship   $');

Doc ID 1314734.1 says it hits a database bug. So, there is always a risk of failures from compiling all forms.

4. Write a script to compile forms file

~~~~~~~~~~~~~~ Script to compile one custom form ~~~~~~~~~~~~~~
# Call:  $ ./script_name.sh forms_name
#
export CUSTOM_TOP=$APPL_TOP/custom     # where the custom form .fmb file is saved under
export FORMS_PATH=$FORMS_PATH:$AU_TOP/forms/US:$AU_TOP/resource:$CUSTOM_TOP/forms/US

Passwd='appsPWD'
custom_top=$CUSTOM_TOP/forms/US

cd $custom_top
custom_form=$1

frmcmp_batch module=$custom_form.fmb userid=apps/${Passwd} output_file=$custom_form.fmx module_type=form compile_all=yes batch=yes

exit 0

~~~~~~~~~~~~~~~~ Compile multiple forms ~~~~~~~~~~~~~~~~~
/path/to/script_name.sh forms_name1
/path/to/script_name.sh forms_name2
/path/to/script_name.sh forms_name3


UPDATES: If frmcmp_batch.sh in R12.1.3 gets ORA-12154 error (or error relates to listener), modify it with workaround described in Dec ID 431324.1 on $TNS_ADMIN:

TNS_ADMIN=${TNS_ADMIN:-$ORACLE_HOME/network/admin}
export TNS_ADMIN

Relinek apps executable file

1. Relink the AutoInvoice Master program (report) as follows: (refer to Doc ID 1209514.1)

a) Log into the Operating System as APPLMGR (on CM node)
b) $ cd $AR_TOP/bin
c) Make a backup copy on file RAXMTR
d) Make sure that Autoinvoice is not running (by checking concurrent jobs)
e) Run the relink script
    $ adrelink.sh force=y ranlib=y "ar RAXMTR"
 
=====log on the screen ==============================
  .....
  Done with link of ar executable 'RAXMTR' on Fri Jul 18 12:51:41 EDT 2014
  Done relinking module RAXMTR in product ar
  Done with link of product 'ar' on Fri Jul 18 12:51:41 EDT 2014
  adrelink is exiting with status 0
  End of adrelink session
  Date/time is Fri Jul 18 12:51:41 EDT 2014

2. To relink 10.1.2 reports executables:
a) $ cd $ORACLE_HOME/reports/lib (or $ORACLE_HOME/reports/lib32)
b) $ make -f ins_reports.mk install

3.To relink 10.1.2 forms executables:
a) $ cd $ORACLE_HOME/forms/lib (or $ORACLE_HOME/forms/lib32)
b) $ make -f ins_forms.mk install

4. Use adadmin to relink all apps programs
   choices:  2 => 1
    If all worked, you will see " adrelink is exiting with status 0 " at the end.
    Log file is $APPL_TOP/admin/${TWO_TASK}/log/adrelink.log

5. Regenerate the jar files with force:
 $ adadmin
   1 => 4. Make sure that you choose force equals Yes.

NOTES/UPDATES
1: Oracle usually suggests "regenerate the jar files with force" after "relink" all form excutables.

2: If below errors exist in the make log file:
    /usr/lib/libXtst.so.6: undefined reference to `__stack_chk_fail@GLIBC_2.4'
    /usr/lib/libXtst.so.6: undefined reference to `__fprintf_chk@GLIBC_2.3.4'
    /usr/lib/libXtst.so.6: undefined reference to `__sprintf_chk@GLIBC_2.3.4'

The fix is to update a required link to a Motif library (as root)
  # unlink /usr/lib/libXtst.so.6
  # ln -s /usr/X11R6/lib/libXtst.so.6.1 /usr/lib/libXtst.so.6

Before the change
$ ls -al /usr/lib/libXtst.so.6
lrwxrwxrwx 1 root root 16 Oct 11  2012 /usr/lib/libXtst.so.6 -> libXtst.so.6.1.0

After the fix, the result shall be
$ ls -al /usr/lib/libXtst.so.6
lrwxrwxrwx 1 root root 29 Jun 18 2014 /usr/lib/libXtst.so.6 -> /usr/X11R6/lib/libXtst.so.6.1
$ ls -al /usr/X11R6/lib/libXtst*
lrwxrwxrwx 1 root root    14 Oct 18  2011 /usr/X11R6/lib/libXtst.so -> libXtst.so.6.1
lrwxrwxrwx 1 root root    14 Oct 18  2011 /usr/X11R6/lib/libXtst.so.6 -> libXtst.so.6.1
-rwxr-xr-x 1 root root 17204 Feb 26  2008 /usr/X11R6/lib/libXtst.so.6.1


3: On Linux RHEL 6 and 7, R12.1 adadmin relink and/or adpatch may hit error
    libgcc_s.so: undefined reference to `__stack_chk_fail@GLIBC_2.4'

The fix is to apply patch 12415211 to 10.1.2 AND 10.1.3 ORACLE HOMES manually (see Doc ID 1525823.1). Below script shall do the job.

#!/bin/ksh
# Steps from Doc ID 761566.1 - search keyword 12415211 (patch number)
# copy file libgcc_s-2.3.2-stub.so from patch folder (

# $ORACLE_HOME/lib/stubs and $IAS_ORACLE_HOME/lib/stubs

echo $ORACLE_HOME
cd $ORACLE_HOME/lib
cp -p -R stubs stubsORIG_`date +%H%M`
pwd
cd stubs
ls -al libgcc_s-2.3.2-stub.so*
cp -p $HOME/RHEL6/libgcc_s-2.3.2-stub.so .
ln -s libgcc_s-2.3.2-stub.so libgcc_s.so.1

$ORACLE_HOME/lib/stubs/libgcc_s.so.1 -> libgcc_s-2.3.2-stub.so
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
echo $IAS_ORACLE_HOME
cd $IAS_ORACLE_HOME/lib

cp -p -R stubs stubsORIG_`date +%H%M`
pwd
cd stubs
ls -al libgcc_s-2.3.2-stub.so*
cp -p $HOME/RHEL6/libgcc_s-2.3.2-stub.so .
ln -s libgcc_s-2.3.2-stub.so libgcc_s.so.1
ln -s libgcc_s.so.1 libgcc_s.so
ls -al libgcc_s*.*


4: One day, after I applied patches to ORACLE HOMEs and applied an AR patch, some AR forms hang and get frozen forever without any error or warning message. The issue was fixed by running steps 3 and 5 above (on each Web node).

R12 Patchset Level, R12 Apps code Level

How to determine R12 Patchset Level (or Module code level) , and module is installed/implemented or not (Doc ID 443699.1)

1. As applmgr or OS environment owner
(a) source environment
(b) login as apps
(c) SQL> @$AD_TOP/sql/adutconf.sql

The adutconf.sql script will create a text file adutconf.lst containing version information and product top information.  There is a section->”Product Installation Status, Version Info and Patch Level”, e.g.
     Product    Appl Status    Version    Patchset Level
     AD           Shared           12.0.0      R12.AD.B.3         

     FND         Installed         12.0.0      R12.FND.B.3       <-- call this "FND code level" also
  • Implemented product has status Installed.
  • Not installed Product has the Status Inactive.
  • Products with status Shared are not fully implemented - only partially installed for dependent Product(s).
  Note: there are exceptions. e.g. WebEDI module (BNE) may be used even its status is Inactive.
           AD = Applications DBA,  FND = Application Object Library (AOL, i.e. Foundation tables). 

2.  Doc ID 550654.1 (for R12.1)
Login to OAM. Choose menu “OAM Support Cart” in upper right hand corner
Navigate to :
(a) Support Cart –> Applications Signature –> Collect –> Check “Product Information” box
(b) Click on “View” (eyeglasses) to get the patchset level report

3.  Script (similar to the one for 11i in Doc ID 443699.1)
SELECT a.application_name, a.application_short_name, a.product_code,  b.patch_level, DECODE (b.status, 'I', 'Installed', 'S', 'Shared', 'Not Installed - N/A') status, b.last_update_date, b.tablespace
FROM  apps.fnd_product_installations b, apps.fnd_application_vl a,
WHERE a.application_id = b.application_id
-- and b.status=’I’
order by a.application_short_name asc;

--  Not sure what is in this table
