Application Servers and Mapviewer

Hey All,
I was wondering if anyone had any suggestions on what application server it's best to run mapviewer on. Is it required to use mapviewer within an Oracle Application Server or OC4J for licensing reasons or is it possible to run mapviewer in whichever server we want without worrying about breaking a licensing agreement? Are there any application servers that are simply incompatible with Mapviewer?
Thanks for the help.

MapViewer should be compatible with any J2EE complied application server. We haven't tested all J2EE app server out there. But it works fine with the ones that we've tested, WLS, Webshere, Tomcat and JBoss.
No matter which app server you end up using, in order to use MapViewer, you must have at least the most basic Oracle App Server license.

Automated Start Stop of Application Servers and CI

Hello,
For our non-production systems, we take offline backups every week. I was just wondering if there's anyone out there who has a UNIX script that can start and stop application servers and the CI when taking an offline backup.
Thanks,
Florencio

Hi,
have you thought about using online backups ? This makes live easier. If you have DB2 9 you can also use online backups including logs to be sure that you can recover your database with just the backup image.
If you have a single-partitioned database, you can use the tool dmdb6bkp to issue an offline backup (forces out any connected application be restarting the database instance, therefore it is not necessary to stop the application servers)
To stop your app server and database you can use thes stopsap script. In the stopdb script you may need to make adjustments to force the database instance stop (the db2stop force command is commented out).
Btw, with DB2 9.5 you can now use online backup include logs also on multi-paritionend DPF databases.

Hardware Sizing for Oracle Application Server and MapViewer

Hi all,
I need to develop an application using Oracle Application Server 10g and MapViewer. The applicaction will, basically, do thematic maps based on a search criteria. The estimative is that we will have 25 users simultaneously using it.
I´d like to have an idea about the hardware to support it.
Do you know where I can get this information?
Any documentation can help.
Regards,
Luis Augusto

Hi Luis,
It may depend on your database size, but I think at least you need to meet the minimum requirements for the Application Server. You can find additional documentation for the AS at http://www.oracle.com/technology/products/ias/index.html.
However I would suggest some extra memory, and if possible the better CPU that you can get. MapViewer will render the spatial features on the server side, and depending on your database size and number of features returned from the queries, this extra memory will help.

SYNC TIME ON APPLICATION SERVERS AND DATABASE SERVERS

Our case is:
We have system used for north america (NA) and system used for Europe (EUP).
North American users are using NA systems (say P510 system), Europe users are using EUP systems (say P710 system).The system time on NA systems are EDT, the system time on EUP systems are CEST
for exmaple:
NA systems:
[CA096658@st1lx014 ~]$ date
Tue Sep 29 20:45:31 EDT 2009
EUP systems:
[CA096658@st1lx008 ~]$ date
Wed Sep 30 02:29:28 CEST 2009
P510 is the production system for NA, there are 4 application servers, 2 database servers, RAC, the system time show up on the os on these 6 servers are not sync, we want to sync the system time on these 6 servers to be the same EDT time. same thing to EUP systems, we want to sync the system time to be the same CEST time.
We need to change that at the unix level, my question is:
1) do we need to change anything at the database and application level ?
2) before we change the time at the unix level, do we need to shutdown application and database ?

>
1) do we need to change anything at the database and application level ?

AFAIK, you do not have to change anything. EBS has the capability to perform timezone conversion. Pl see MOS Doc 330075.1 (User Preferred Time Zone Support Guidelines for Applications 11i10CU2)

It is best practice to shut down all applications/databases before changing server time.

Schedule a Background Job to Available Free Application servers

Hi,
There is a requirement to develop a Wrapper program,which needs to schedule Background jobs by checking all the available free application servers and assigning it to them.
For Eg: If there are 5 application servers in LIVE system,Then this program needs to find free application server's which will submit the job to that particular free server
Appreciate Your Inputs!!
Thanks
Rakesh

Look at some documentation like [Scheduling Background Jobs |http://help.sap.com/erp2005_ehp_04/helpdata/EN/c4/3a7f87505211d189550000e829fbbd/frameset.htm] (look for "system load balancing")

SAP R/3 Enterprise : Background job run on application servers

Hello All,
For our SAP system (SAP_BASIS 620, SAP_ABA 620,SAP_APPL 470), there are 5 application servers and one central instance.
We have a Background job that connects to external non sap system for data delivery via RFC of Type "G" i.e.HTTP Connection to Ext. Server with port 443 . RFC works fine.
In transaction STRUST, SSL certificates are also installed to enable the https connectivity from R3 system.
Our current issue is that background jon runs on one of the application server correctly and is able to transfer that data to external system. However if same job runs on other 4 application server, it fails to connect to external server and throws error:
RFC Destination XXXX not defined
407 Unknown error
Failed to store the XML content
Error in the XML document: 1301540.xml
407 Unknown error
This is very starnge for us .RFC is working correctly every time but background job works on one AS and not on other AS.
Where and What can be the difference in application servers.
Please help to send in ur replies. Thanks

Hi,
Is there a firewall between the non SAP system and the SAP system ? It could be that firewall rules have only been set for one only of the SAP application servers ?
Did you check the HTTP connections from each application server ?
Did you check that the ICM is running on each SAP application server ?

How do the application servers connect the new database after failing over from primary DB to standby DB

How do the application servers connect the new database after failing over from primary DB to standby DB?
We have setup a DR environment with a standalone Primary server and a standalone Physical Standby server on RHEL Linux 6.4. Now our application team would like to know:
When the primary DB server is crashed, the standy DB server will takeover the role of primary DB through the DataGuard fast failover. As the applications are connected by the primary DB IP before,currently the physical DB is used as a different IP or listener. If this is happened, they need to stop their application servers and re-configure their connection so the they coonect the new DB server, they cannot tolerate these workaround.
Whether does oracle have the better solution for this so that the application can automatically know the role's transition and change to the new IP without re-confige any connection and shutdown their application?
Oracle support provides us the answer as following:
==================================================================
Applications connected to a primary database can transparently failover to the new primary database upon an Oracle Data Guard role transition. Integration with Fast Application Notification (FAN) provides fast failover for integrated clients.
After a failover, the broker publishes Fast Application Notification (FAN) events. These FAN events can be used in the following ways:
Applications can use FAN without programmatic changes if they use one of these Oracle integrated database clients: Oracle Database JDBC, Oracle Database Oracle Call Interface (OCI), and Oracle Data Provider for .NET ( ODP.NET). These clients can be configured for Fast Connection Failover (FCF) to automatically connect to a new primary database after a failover.
JAVA applications can use FAN programmatically by using the JDBC FAN application programming interface to subscribe to FAN events and to execute event handling actions upon the receipt of an event.
FAN server-side callouts can be configured on the database tier.
FAN events are published using Oracle Notification Services (ONS) and Oracle Streams Advanced Queuing (AQ).
=======================================================================================
Who has the experience and the related documentation or other solutions? we don't have the concept of about FAN.
Thank very much in advance.

Hi mesbeg,
Thanks alot.
For example, there is an application JBOSS server connecting the DB, we just added another datasource and put the standby IP into the configuration file except adding a service on DB side like this following:

                </drivers>

If the failover is occurred, the JBOSS will automatically be pointed to the standby DB. Additional actions are not needed.

What is application server and role of it?

i need information about application layer in abap.

hi Anil,
Please check these links:
http://help.sap.com/saphelp_nw2004s/helpdata/en/69/c24e034ba111d189750000e8322d00/content.htm

Overview of SAP Application Servers
Use
You can display a list of application servers that have registered themselves with the SAP message server by executing transaction SM51, or by choosing Administration ® System Administration ® Monitor ® System Monitoring ® Servers. From their status you can recognize which application servers are active in this SAP system.
You can also administer the application servers, and manage and display the status of the users and work processes in all application servers belonging to the SAP system.
Components of Application Server
Work Processes
Work processes are components that are able to execute an application (that is, one dialog step each). Each work process is linked to a memory area containing the context of the application being run. The context contains the current data for the application program. This needs to be available in each dialog step.
Dispatcher
The dispatcher is the link between the work processes and the users logged onto the ABAP application server (that is, the SAP GUIs of theseusers). Its task is to receive requests for dialog steps from the SAP GUI and direct them to a free work process. In the same way, it directs screen output resulting from the dialog step back to the appropriate user.
Gateway
This is the interface for the communication protocols of NetWeaver AS ABAP (RFC, CPI/C). It can communicate with other ABAP application servers of the same NW AS, with other SAP Systems, or with external non-SAP systems.
Shared Memory
All of the work processes on an ABAP application server use a common main memory area called shared memory to save contexts or to buffer constant data locally.
Hope this will help.
Regards,
Nitin.

Multiple PIA/Application servers to one database?

We're planning an upgrade to PT 8.50, FSCM 9.1 and with this upgrade we want to add access for outside customers/vendors. What's the best way to configure an internal employee site/app, and a customer site/app to one production database? Is it as simple as installing different application servers and PIAs, point them all to the one database, and configure 1 PIA as EMPLOYEE and the others as CUSTOMER? Or should we also need use Portal 9.0? I've been doing some research into this, but was hoping to hear some real-world experience and advice from anyone else that's set up anything similar.
Thanks,
-rob

you can have a PIA built for outside customers hitting the same database.
you can even have separate PIA hitting same app servers and db.
If you are planning on having an external site outside your firewall - for CUSTOMER (portal) make sure the external site is built to work only for CUSTOMER portal.
u might also want to design your customer ID base - using specific permissions and roles.
hope this helps.

Issues with sharing a single OID with two Application servers (9.0.4)

We have two installations of 9.0.4 Application Servers and both share the same OID. We use Oracle Portal for deploying our jsp applications.
All users in the OID are sync'ed from Microsoft Active Directory.
Application Server 1 is for an application X
Application Server 2 is for an application Y
We create groups in the portal of Application Server 1 specifically for Application X. DEF_GROUP1 is default group for all applications in application X
DEF_GROUP1 has a default page - Page 1. DEF_GROUP 1 does not exist in Application server 2
We create groups in the portal of Application Server 2 specifically for Application Y. DEF_GROUP2 is default group for all applications in application Y
DEF_GROUP2 has a default page - Page 2
DEF_GROUP2 does not exist in application server 1
We have users who access both application X and applicaiton Y
For a user "JOHN" we assign DEF_GROUP1 in the user profile on the portal in Application Server 1
When we go to the user profile of "JOHN" on application server 2, we find that DEF_GROUP1 is a default group in the user profile of user "JOHN"
If we change it DEF_GROUP2, then the default group on the portal of application server 1 automatically changes to DEF_GROUP2.
Why is this so ? We would like to have a different default group for the same user in the two portal repositories. ?
Can any one provide some insight into this issue ?

Basically I started to develop this system inside Oracle AS and then when it came time to passing a request to a new page, it crapped out on me on the App. Server. So instead of trying to fix the problem there and then I continued to develop outside Portal and inside Jdeveloper. After a week or two once all my stuff worked perfectly I try and take it back into Portal but only the first JSP of all my Portlets would show up, because as soon as I would submit a form and the action directed me to a new page and Portal would be lost/confused. Obviously I shouldn't have done it that way but none the less...
So now I'm reading through the documentation you pointed me towards and it seems I have to qualify my parameters and then "attach" them to the url which the form will pass to the actioned page. I'm importing numerous classes (...urlUtils, etc) in order to qualify the parameters and then build this url without affecting any parameters currently present that my portlet does not own.
What I'm rambling towards here is all this separation of logic and presentation and the whole nine, implies different people can develop different parts of a 'system' mostly independant of one another...so in my situation I shouldn't in huge trouble yet, since underlying everything is a working system. My issue is with oracle and the App Server. If I take my code which works great outside of the App. Server and I fully qualify parameters and make sure my form actions are constructed using the UrlUtils in order to fully qualify them as well, and then I make sure page parameters are mapped to the proper portlet parameter values....should my system work on the App Server (assuming everything is done properly)....or am I still missing something.

One iPlanet using two application servers?

Can anyone help, is it possible for one iplanet 6.0 instance using/connecting two application servers (i.e. one is JRun server, another is Webspere server) at the same time?
If so, how to do it?

I don't see why not. I have had the same webserver talking to both iplanet 6.5 and sunOne 7. As both the application servers will connect vias a plugin I would suggest you follow the instructions for both application servers and see what happens.

Advantages of using a webserver inbetween a load balancer and application servers

I am building out a new weblogic domain.
I am wondering which one of these configuration to go with:
1. Load balancer > weblogic servers
2. Load balancer > web server > weblogic servers
Could someone tell me what are the specific advantages of having web servers inbetween a load balancer and application servers (besides caching static data content and acting as a proxy)?
Thanks in advance
Srini

Other than hosting the static content, nothing much really. We have our load balancer go straight to WL for applications without static content and route to web server if there is static content. Easy enough to do it both ways, best of both worlds.

Configure CRS2008 to using AD and Kerberos with Java application servers.

Hi All,

My problem is failed to logon CMC and infoview and got error message at below:
Account Information Not Recognized: Active Directory Authentication failed to log you on. Please contact your system administrator to make sure you are a member of a valid mapped group and try again. If you are not a member of the default domain, enter your user name as UserNameatDNS_DomainName, and then try again.
Actually, I am sucessful to logon Business View manager with CRuser1. However, I fail to logon CMC and infoview and got the above error. Have you any suggestion to solve this problem?
Ken.

if you can logon with client tools then that should be an indication that the service account running the CMS IS working! Good news.
So the problem is likely with the java portion (krb5/bsclogin or java options)
If the files are in c:\winnt\ (if not copy them there) and perform c:\program files\business objects\javasdk\bin\kinit username
then enter and password/enter again
Probably get the same message. To note in your krb5.ini all domain info must be in CAPS (the .com appears to be in lower case)
kinit works with just the krb5.ini, java SDK and AD (removing BO config and the service account from the picture). Once that works if your java options are specified properly you should be able to login to CMC/infoview.
also 1 last point. Add udp_preference_limit = 1 to the krb5 lib defaults section
libdefaults
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
udp_preference_limit = 1
