Oracle Application in DMZ (Demilitarized Zone)

DMZs For Civilians

In the IT industry, a demilitarized zone is a single or multi-segment perimeter network that demarks the portion of the corporate network that lies between the intranet and outside networks. Corporate DMZ borders are enforced by firewalls and other dedicated networking devices.

DMZs for the E-Business Suite

AutoConfig supports the use of DMZs with the E-Business Suite Release 11i, and an increasing number of our customers have either already implemented them or are planning to do so. This is a common configuration:

In the configuration above, there are two different E-Business Suite application servers, each with its own unique domain name and setup. External users access the E-Business Suite via the external "acme.company.com" address, and internal users access it via the "staff.acme.com" address.

Different Responsibilities for Internal and External Servers

It's possible (and recommended) to restrict the general set of Applications Responsibilities based on the application server that you're using.

For example, there should be no reason to allow external users to modify your company's Chart of Accounts, so that responsibility can't be used if the end-user is logging in from outside the corporate intranet.

Possible Weak Points

There are two possible weaknesses with the first configuration shown above:

If your external firewall is compromised, your external application server is also compromised, exposing an attack on your E-Business Suite database.
There's nothing to prevent your internal users from attacking your internal application server, also exposing an attack on your E-Business Suite database.

Reverse Proxies and DMZs

If you're concerned about your external firewall being hacked, one possible countermeasure is to use layered DMZs and put a reverse proxy in the first DMZ.

The reverse proxy has restricted capabilities and and the authority only to speak with the external application server. It's possible to use the following as reverse proxies with the E-Business Suite:

Oracle Web Cache
Oracle HTTP Server
Other third-party reverse proxy servers, including Apache and Microsoft Proxy Server

An Inside Job

I'm a big fan of heist and con artist movies. According to Hollywood, you can't pull off a big job without someone on the inside.

It seems a lot of IT security analysts are fans, too, since they regularly publish surveys that suggest that the majority of security breaches are the result of employees with their hand in the till. If we're to learn anything from movies, it's this: trust nobody, not even your internal end-users.

That's why the second configuration above shows the E-Business Suite database server protected by its own firewall. Even if your internal application server is compromised by an industrious but disgruntled fellow employee, your database is still protected.

Scratching the Surface

There are a number of other interesting DMZ-related architectural options for the E-Business Suite. If you'd like to get more details, the following document is recommended reading:

The XML Publisher Concurrent Request Fails Due to the Output Post Processing

Three possible errors can occur as below:

The Output Post Processor is not running or does not pick up the request

…
+————- 1) PUBLISH ————-+
Unable to find an Output Post Processor service to post-process request [request_id].

Check that the Output Post Processor service is running.
+————————————–+
…

Solutions:

* Verify that the Output Post Processor is enabled and active.
* If confirmed, retrieve the OPP log file either via the Forms application or via the Oracle Application Manager.
– Via the Forms application:

Login to the application as SYSADMIN
Responsibility: System Administrator
Function: Concurrent –> Manager –> Administration
Select the Output Post Processor
Click on the Processes button
Select the Concurrent Process which was active during the time that the request ran
Click on the Manager Log button to open the Output Post Processor log file

– Via the Oracle Application Manager

Login to the application as SYSADMIN
Responsibility: System Administration
Function: Oracle Applications Manager –> Concurrent Managers
Select the Output Post Processor Service and click on View Details
Click on View Processes
Select the Concurrent Process which was active during the time that the request ran
Click on the Log button to open the Output Post Processor log file

The Output Post Processor is running but has not picked up the request

... +------------- 1) PUBLISH -------------+ The Output Post-processor is running but has not picked up this request.No further attempts will be made to post-process this request, and the request will be marked with Warning status. Setting the profile option Concurrent: OPP Response Timeout to a higher value may be necessary. +--------------------------------------+ ...

By default a timeout will occur if it takes longer then 120 seconds (2 min.) for the Output Post Processor to pick up the request from the Concurrent Manager process. In that case, the Concurrent Request will complete with status Warning and the Request log file will contain error message like above.

Solutions:

* Increase the value (in seconds) for the profile option ‘Concurrent:OPP Response Timeout‘.

The concurrent manager has timed out waiting for the Output Post-processor to finish this request

…
+————- 1) PUBLISH ————-+
The concurrent manager has timed out waiting for the Output Post-processor
to finish this request.

Check that there are enough Output Post-processor service processes running.
More information may be found in the service process logfile.
+————————————–+
…

The concurrent manager process has successfully invoked the OPP but it a timeout is encountered as the OPP takes too long to complete the job.

The time that this takes will depends on various elements such as:

size of the XML Data File
complexity of the template
performance of the server
….

By default a timeout will occur if it takes longer then 300 seconds (5 min.) for the XML Publisher engine to generate the output file. The Concurrent Request will complete with status Warning and the Request log file will contain error message like above.

Solutions:
* Increase the value (in seconds) for the profile option ‘Concurrent:OPP Process Timeout‘.

Output Post Processor (OPP) Log Contains Error “java.lang.OutOfMemoryError: Java heap space”
java.lang.reflect.InvocationTargetException Caused by:java.lang.OutOfMemoryError: Java heap space atoracle.xdo.parser.v2.XMLDocument.createNodeFromType(XMLDocument.java:2869) atoracle.xdo.parser.v2.XMLDocument.createNodeFromType(XMLDocument.java:3000)

Solutions:

1. Determine what the heap size per OPP process is currently:

select DEVELOPER_PARAMETERS from FND_CP_SERVICES
where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUES
where CONCURRENT_QUEUE_NAME = ‘FNDCPOPP’);

2. The default should be:

J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx512m

3. Increase the Heap Space per Process to 1024:

update FND_CP_SERVICES
set DEVELOPER_PARAMETERS = ‘J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx1024m’
where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUES
where CONCURRENT_QUEUE_NAME = ‘FNDCPOPP’);

4. Bring the managers down.
5. Run cmclean.sql script from Note 134007.1 – CMCLEAN.SQL Non-Destructive Script to Clean Concurrent Manager Tables.
6. Bring the managers up again.

1. Log into applications with the System Administrator responsibility.
2. Navigate to Concurrent -> Program -> Define
3. Query the XML Publisher Template Re-Generator program
4. Set the following value for the Executable Options : -Xmx1024m
5. Save changes.
6. Retest the program.

Configure the XML Publisher Administrator Configuration settings.
1. As XML Publisher Administrator navigate to Administration->Configuration.
2. Under Temporary Directory pick a temporary file location on your concurrent processing node. This should be at least 5GB or 20x larger than largest XML data file you generate
3. Under FO Processing, set:
o Use XML Publisher’s XSLT processor set to True
o Enable scalable feature of XSLT processor set to False
o Enable XSLT runtime optimization set to True

Issue resolved.

The referenced database doesn't contain a valid management Repository.

OMS 13c agent installation failed with "The referenced database doesn't contain a valid management Repository."

Cause :-

Generally this error comes when the database we are using as OMS database was already used as a database for OMS installation before or A failed OMS installation already happened using this database.

Error:-
The referenced database doesn't contain a valid management Repository.

Solution :-

we have to properly clean the database before using it again as a OMS database :-

Below steps I did to clean my database :-

1. Drop sysman related schemas.

[ACSDB@acs-oem13c ~]$ . .bash_profile
[ACSDB@acs-oem13c ~]$ sqlplus / as sysdba

SQL> DROP USER SYSMAN CASCADE;

User dropped.
SQL> DROP USER SYSMAN_OPSS CASCADE;

User dropped.

SQL> DROP USER SYSMAN_MDS CASCADE;

User dropped.

SQL> DROP USER SYSMAN_STB CASCADE;

User dropped.

SQL> DROP USER SYSMAN_BIPLATFORM CASCADE;

User dropped.

SQL> DROP USER SYSMAN_RO CASCADE;

User dropped.

2. Remove Synonyms related to sysman accounts :-

DECLARE
CURSOR l_syn_csr IS
SELECT 'DROP ' ||
CASE owner
WHEN 'PUBLIC'
THEN 'PUBLIC SYNONYM '
ELSE 'SYNONYM ' || owner || '.'
END ||
synonym_name AS cmd
FROM
dba_synonyms
WHERE
table_owner IN (
'SYSMAN',
'SYSMAN_MDS',
'MGMT_VIEW',
'SYSMAN_BIP',
'SYSMAN_APM',
'BIP',
'SYSMAN_OPSS',
'SYSMAN_RO'
);
BEGIN
FOR l_syn_rec IN l_syn_csr LOOP
BEGIN
EXECUTE IMMEDIATE l_syn_rec.cmd;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line( '===> ' || l_syn_rec.cmd );
dbms_output.put_line( sqlerrm );
END;
END LOOP;
END;
/

PL/SQL procedure successfully completed.

3. Removing remaining Objects and tablespaces :-

SQL> DROP USER mgmt_view CASCADE;

User dropped.

SQL> DROP TABLESPACE mgmt_ecm_depot_ts INCLUDING CONTENTS AND DATAFILES CASCADE CONSTRAINTS;

Tablespace dropped.

SQL> DROP TABLESPACE mgmt_tablespace INCLUDING CONTENTS AND DATAFILES CASCADE CONSTRAINTS;

Tablespace dropped.

SQL> DROP TABLESPACE mgmt_ad4j_ts INCLUDING CONTENTS AND DATAFILES CASCADE CONSTRAINTS;

Tablespace dropped.

4. As proper database cleaning using RepManager dropall didn't happen, so we have to clean up the registry details :-

DELETE
FROM
schema_version_registry
WHERE
(comp_name,owner) IN (
('Authorization Policy Manager','SYSMAN_APM'),
('Metadata Services','SYSMAN_MDS'),
('Oracle Platform Security Services','SYSMAN_OPSS')
);

2 rows deleted.
SQL> commit;

Commit complete.

SQL> ALTER SYSTEM SET optimizer_dynamic_sampling = 0 SCOPE=both;

System altered.

How To Resize the Online Redo Logfiles

1. First see the size of the current logs:

> sqlplus /nolog
SQL> connect / as sysdba

SQL> select group#, bytes, status from v$log;
GROUP# BYTES STATUS
———- ———- —————-
1 1048576 INACTIVE
2 1048576 CURRENT
3 1048576 INACTIVE

Logs are 1MB from above, let’s size them to 10MB.

2. Retrieve all the log member names for the groups:

SQL> select group#, member from v$logfile;

GROUP# MEMBER
————— —————————————-
1 /usr/oracle/dbs/log1PROD.dbf
2 /usr/oracle/dbs/log2PROD.dbf
3 /usr/oracle/dbs/log3PROD.dbf

3. Let’s create 3 new log groups and name them groups 4, 5, and 6, each 10MB in size:

SQL> alter database add logfile group 4 '/usr/oracle/dbs/log4PROD.dbf' size 10M;
SQL> alter database add logfile group 5 '/usr/oracle/dbs/log5PROD.dbf' size 10M;
SQL> alter database add logfile group 6 '/usr/oracle/dbs/log6PROD.dbf' size 10M;
4. Now run a query to view the v$log status:

SQL> select group#, status from v$log;
GROUP# STATUS
--------- ----------------
1 INACTIVE
2 CURRENT

3 INACTIVE

4 UNUSED

5 UNUSED

6 UNUSED

From the above we can see log group 2 is current, and this is one of the
smaller groups we must drop. Therefore let’s switch out of this group into
one of the newly created log groups.

5. Switch until we are into log group 4, so we can drop log groups 1, 2, and 3:

SQL> alter system switch logfile;
** repeat as necessary until group 4 is CURRENT **

6. Run the query again to verify the current log group is group 4:

SQL> select group#, status from v$log;

GROUP# STATUS
——— —————-
1 INACTIVE
2 INACTIVE
3 INACTIVE
4 CURRENT
5 UNUSED
6 UNUSED

Note: redo log Group 1 or 2 or 3 can be active after “alter system switch log file”
which means could not be dropped, in this case,
you need to do “alter system checkpoint” to make redo log groups 1,2 and 3 inactive.

7. Now drop redo log groups 1, 2, and 3:

SQL> alter database drop logfile group 1;
SQL> alter database drop logfile group 2;
SQL> alter database drop logfile group 3;

Verify the groups were dropped, and the new groups’ sizes are correct.

SVRMGR> select group#, bytes, status from v$log;

GROUP# BYTES STATUS
——— ——— —————-
4 10485760 CURRENT
5 10485760 UNUSED
6 10485760 UNUSED

8. At this point, you consider taking a backup of the database.

9. You can now go out to the operating system and delete the files associated
with redo log groups 1, 2, and 3 in step 2 above as they are no longer
needed:

% rm /usr/oracle/dbs/log1PROD.dbf
% rm /usr/oracle/dbs/log2PROD.dbf
% rm /usr/oracle/dbs/log3PROD.dbf

Output Post Processor (OPP) in oracle R12

What is Output Post Processor?

Concurrent Processing now uses the Output Post Processor (OPP) to enforce post-processing actions for concurrent requests.Post-processing actions are actions taken on concurrent request output. An example of a post-processing action is that used in Concurrent Processing support of XML Publisher.
If a request is submitted with an XML Publisher template specified as a layout for the concurrent request output, then after the concurrent manager finishes running the concurrent program, it will contact the OPP to apply the XML Publisher template and create the final output.

OPP runs as a service that can be managed through Oracle Applications Manager (OAM) from the System Activity page (Navigation: Applications Dashboard > Applications

Service (from the dropdown list) > Go).

The integration of XML Publisher within Concurrent Processing is done by means of a specialized concurrent manager called the Output Post Processor (OPP). If a request is submitted which has an XML Publisher template specified as a layout for the output, then after the concurrent manager finishes running the concurrent program, it will contact the OPP to apply the XML Publisher template and create the final output.

An overview of the actions involved:

1. An application user submits an XML Publisher based report.
2. The standard concurrent manager processes the request.
3. The XML data file is generated by the standard concurrent manager. This can be done by various methods:
o Oracle Reports - Report Definition File (RDF)
o XML Publisher Data Template - XML data template linked to the Data Definition
o Any other process that produces XML output
4. A post processing action defines that the output needs to be generated by the Output Post Processor hence it is triggered by the standard manager.
5. The Output Post Processor generates the final report and informs the standard concurrent manager whether that was successful.
6. The standard concurrent manager finalizes the concurrent request.

Processes in OPP:

There should always be at least one OPP process active in the system. If no OPP service is available to process concurrent requests, completed requests that require OPP post-processing will complete with a status of Warning.

One service instance of the OPP service is seeded by default. This seeded OPP service instance has one workshift with one process.

A concurrent manager contacts an available OPP process when a running concurrent request needs an OPP post-processing action. Concurrent managers use a local OPP process (on the same node) by default, but will choose a remote OPP if no local OPP process is available.

How to Increase the number of Output Post Processors?
1.Log on to Applications with “System Administrator” responsibility.
2.Navigate to Concurrent -> Manager -> Define.
3.Query for the “Output Post Processor” service.
4.Click on “Work Shifts” and increase the number of processes

How to get OPP manager log file location?

$APPLCSF/log/<SID>/FNDOPP####.txt OR
1,System Administrator > Concurrent > Manager > Administer
2,Search for ‘Output Post Processor’
3,Click the ‘Processes’ button .
4,Click the Manager Log button. This will open the ‘OPP’
Upload the OPP log file.

In some cases, Output Post Processor is not start up and it shows Actual and Target are showing different values when we query for Output Post Processor.
The log files shows that no error message.In this case apply the following possible solution for starting the OPP.

1. Shutdown the internal manager by using adcmctl.sh stop apps/apps
2. Make sure there is no FNDLIBR processe running:
$ ps -ef| grep FNDLIBR OR ps -ef|grep applprod|grep FNDLIBR
3. If there is any FNDLIBR processe please kill it $ kill -9 pid
4. Run cmclean.sql script as document from Note 134007.1
5. Restart the internal manager by using adcmctl.sh start apps/apps

Solution:
1,System Administator > Concurrent > Manager > Administer
2,Query "Output Post Processor" -> Processes button
Get the sytem id of "Output Post Processor"
3,ps -ef|grep [system id]
4,kill -9 [system id] in Unix
5,System Administator > Concurrent > Manager > Administer
6,Query "Output Post Processor" -> Restart button
