Does Web Center has the functionalities like SSO, Session Management?
Hello,
Does Web Center has the functionalities like SSO, Session Management, LDAP support? If we replace Oracle Portal with Web Center then we assume that we would have all the backend funationalities?
Any help is highly appreciated.

Oracle Application Server Control
Oracle AS Control is a JEE application (literally an EAR) that runs in OC4J. It sounds like you only installed the web server (OHS) but no application tier (i.e. managed OC4J instances). Thus, Oracle AS Control is not installed. When you further install some OC4J containers, AS Control will be automatically installed there.

Database & IDM requirements
Don't you need a database license too? From what I've seen of 10.1.3 application server, it doesn't insatall a database. One of the prerequisites for installing WebCenter is Content DB, which its self needs a 10.1.0.5 or 10.2.0.2 database.
What about Identity Management? It also looks like you need to have a seperate Application Server infrastructure to provide Oracle SSO and IDM.
Can anyone clear this up?

Oracle WebCenter vs. Collaboration Suite
Ok, I was reading about Oracle WebCenter on the Oracle Magazine, actually Vince Casarez was intervied in this article. He was talking about the benefits of this new technology, and I cuote: "...customers can start to leverage the most-popular Web 2.0 services within their enterprise today, including online discussions, enterprise wikis for collaboration around different projects..."
Ok, maybe it's because I'm new on this technology, but didn't the Collaboration Suite allready accomplish that? What's the destiny of OCS??

Why not EJBs?
Well, if you look in to JDeveloper 11g evolution, form Tp1 to Tp4, you will notice:
1. In TP1-TP2, EJBs were technology choice in Fusion Application stack.
2. In TP1-TP2, EJBs support was much improved (data controls, bindings, wizards...) compared to 10g. For me it was clearly visible that Oracle is investing in EJBs as well as into EclipseLink.
3. After TP3, BCs are again put in the middle again (Fusion dev stack now again is ADF RC + BCs). EJBs support was staled – no new wizards, empty placeholders in wizards for EJBs etc.
Coinciding with Oracles numerous acquisitions (BEA WebLogic), latency in Fusion AS 11g production (migration of old PL/SQL code to true ADF RC multitier Web UI), I beleive they decided to drop EJBs as platform for porting 11g (as it is much easier with BCs when you have a lot of legacy PL/SQL code and SPs). While EJB 3.1 and JPA 2.0 is much advanced and Java-friendly that BCs, they decided to postpone support for EJBs in R1 (both Fusion 11g AS and JDev 11g) as they don't need them right now and they will be ready when new standards are in place (they will got some breathing space with just porting UI to ADF RC while middle-tier is good enough even on BCs).
Regarding declarative validation, please note that JPA 2.0 will support Bean Validation annotations (JSR-303). So, BCs declarative validation is nothing special and is much simplified compared to JSR-303.
So, if we neglect Oracles emotive relation to BCs as well as pragmatic reasons (hurry to deliver new, fancy, Rich UI to their apps), the future of EJBs is much brighter than BCs. You can promote ADF Methodology with BCs is focus, but you will make a bad influence on many developers which will go that way and learn (in year or two) that there is something much better out there (named EJBs, in core of JEE 6 coming next year).

Inactive sessions
Dear jeegar,
in Oracle inactive session are managed automatically,
but even though u wana check the sessions status live and all the other things related to sessions like
PGA size, logon time, phs reads, excute time, parse counts, rollback count, commit count, os-username, machine....
and so on.
then you must go in the administrative tools.
then area is top session system/manager.
here you can see all the related things with session.
and you graphically manage the session even kill the sessions.

Why companies are not using EM Grid Control
After playing around with it, we found several issues:
1. It was almost impossible to install on AIX. We had several SR's opened with Oracle about the Java installer. We ended up putting it on Linux.
2. Performance. Oracle Application Server is a resource pig. You need at least 1GB of Ram and a Dual Core CPU to handle it.
3. In EM9i, we had a Low Archive Log Space event triggered an RMAN Backup job would clean out the directory. Even Oracle couldn't figure out how to create that in Grid Control.
4. Performance Manager. I liked the Dash Board look and the fact that you could set the refresh rate as low as 5 seconds. You can't do that in Grid Control. Oracle, Give it Back!!!!
5. The Tablespace Map Graphic in EM9i was killer. It was great to show non-Oracle people, how the extents were organized in a tablespace. Can I do that in Grid Control?
Overall, it's not a bad product for a first release. Oracle needs to clean it up though. Considering I've been an Oracle DBA since version 6.0.29, I'll take it over what I had then. We'll see what 11g brings to the table.
