User connection in RAC

how can to find out that user is using vip or ip address for conneciton to database.
can we find out without looking users tnsnames file....?????

Look at the SYS_CONTEXT function. Using it, in conjunction with queries of gv$session, should get you what you want.
I would consider it "Best Practice" in RAC to never allow users to connect to anything other than services. One way to stop them
from doing what you do not want them to do is either replace their TNSNAMES files, not always effective. The other is to change
the instances names ... which will stop them dead in their tracks every time.

Which user connected from which node in RAC

Hi All,
I have installed 2-node Oracle 10g R2 RAC on RHEL4. It is working fine. Now i want to know which user connected from which node, how can i know this details?
Thanks,
Praveen.

You can use the gv$ views which actually submit the query ran against them to all instances of Oracle for the RAC database.
The documentation for the gv$ views is the v$ view entry in the Reference manual.
As far as I know when you run RAC every v$ view is built on a gv$ view.

User connections to the RAC/standby instances

Before I setup the client failover practices, I tested user connection to my RAC instances.
1st I shutdown one instance, of course all connection will go to remaining instance.
However when both RAC instances are up and running, any new connection goes to instance 1.
Is this normal ? Is that the way supposed to be?

Is this normal ? Is that the way supposed to be?If any new connections are coming.. if load balancing configure properly these sessions should be shared across the cluster.

Cannot send email via ActiveSync when user connect from Internet (Exchange 2010 SP3 RU5)

Hi All.
This is the first time I encounter this kind of issue, whenever user connect from the internet they cannot send email from their Phone or Windows Mail App, but they can retrieve email
But when they connect from Internal Network they can send email. I already test ActiveSync from internet using www.testexchangeconnectivity.com and it pass all tests.
I also check the Firewall and all the necessary ports already opened (we even open all ports) , the default TTL on the firewall 3600 second.
From what I read ActiveSync use some kind of HTTP POST or in MS terminology "PING" command, but still have no idea what kind of configuration that should be made to the Firewall so it can pass this "PING" command. Because from what I
see in Android Logcat the problem always related to this PING command

Hi ronaldosy,
How about the work flow of Outlook or OWA on PC internally/externally?
If only phone has this issue, I suggest ask ActiveSync Forum for help so that you can get more professional suggestions. For your convenience:

How to find the number of users connected to database from OS level(Linux)

Hi All,
Could anyone know , how to find the number of users connected to database without connecting with sql*plus
is there any command to find it?
example we have 10 databases in one server, how to find the number of users connected to particular database without connecting to database(v$session)?
oracle version:- 10g,11g
Operating System:- OEL4/OEL5/AIX/Solaris
any help will be appreciated.
Thanks in advance.
Thank you.
Regards,

Excellent.
Tested, works as long as you set the ORACLE_SID first ( to change databases )
ps -ef | grep $ORACLE_SID | grep "LOCAL=NO" | awk '{print $2}' | wc -l
Thanks!

How to make Adobe acrobat feature to convert SAP Pages to PDF available for multiple users connected to the same server

We have installed Adobe Acrobat X Pro- English,Francais,Deutsch version 10.1.9 in our test environment and tried testing it for converting SAP pages into PDF with a few pilot users. In doing so we faced a challenge, where only one user at a time can use Adobe Acrobat PRO to convert SAP pages in to PDF.As long as the first user who is connected to Adobe Acrobat Pro via SAP isn’t logged off, other users connected to the same server are not being able to get the “Save As” dialog box to save the PDF in their preferred location.
This is a business requirement and we need an urgent solution for the same. Can anyone help us in telling us if this is possible and if yes the how to go about?

It's not something we deal with here, the LiveCycle products are a different world. Key points: Adobe LiveCycle is a range of products, some desktop, some server. LiveCycle PDF Generator is the one you should look at, it comes in 3 editions. License terms are by negotiation. Key management is via its Java API.

How to provide access to multiple users connected to a Dumb switch? (multi-auth/multi-domain)

Good morning everybody,
I am writing on behalf of not being able to implement a desired outcome in our company network. In fact the situation is as follows:
What I want to do is to be able to authenticate users (802.1x authentication) in our company radius server and authorize them access by having a dynamic VLAN assignment in a multi-user environment on one and the same port of a Cisco 2960 switch. So far, the authentication and authorization has been working completely smoothly (there are no problems with itself). The concept involves the configuration of both DATA and VOICE VLANs as I there is also phone authentication implemented. In order to simulate this environment I introduce a Dumb switch connected to my Cisco 2960 Catalyst.
What I have successfully managed to get to work so far is this:
1) On one switch port I have tried the “authentication host-mode multi-domain” and it worked perfectly for a PC behind a telephone, or with one PC connected to a the dumb switch + the telephone connected to another port of the dumb switch. Logically it is the same situation as there is a separation in two domains – DATA and VOICE. Bellow is an output from show authentication sessions for this scenario.
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
2) On the other hand, when I try the same scenario with the “authentication host-mode multi-auth”, the switch still separates the traffic in two domains and is able to authenticate all users, AS LONG AS they are in the same VLAN.
show authentication sessions:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
However, I cannot succeed authentication of many users from DIFFERENT VLANs, neither in multi-auth nor in multi-domain modes.
What I want to get is an output like this:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
I want the switch to authenticate the users anytime they connect to itself and for them to have an instant access to the network. (I tell this because I tried scenario 1) with multi-domain mode and authentication violation replace, and it worked but, two users never had access to the “Internet” simultaneously!!!
The configuration of the interface connected to the Dumb switch is as follows.
interface FastEthernet0/x
description Connection to DUMBswitch
switchport mode access
switchport voice vlan XXX
switchport port-security maximum 10
switchport port-security
switchport port-security violation protect
authentication host-mode multi-auth
authentication priority dot1x
authentication port-control auto
authentication timer reauthenticate 4000
authentication violation replace
dot1x pae authenticator
dot1x timeout tx-period 10
spanning-tree portfast
The way I see it is explained in the following steps:
- PC1 connects to the Dumb switch. This causes the Cisco switch to authenticate user1. This creates an auth. session with its MAC address linked to a domain DATA.
- When PC2 connects to the Dumb switch, this causes the violation replace which replaces the recent authenticated MAC address with the MAC of PC2. I would like it once authenticated to appear in the authentication sessions with a link to a new DATA domain linked to the VLAN assigned from the RADIUS server.
Is this possible? I think (in theory) this is the only way to provide authenticated access to multiple users connecting through Dumb switch to the network.
Has anybody ever succeeded in such a configuration example and if yes, I would be love to get some help in doing so?
Thank you
Stoimen Hristov

Hi Stoimen,
I have done a setup similar to yours with the only exception being VLAN assignment. When I used dACLs only, it makes things somewhat easier as the VLAN no longer matters. Remember that the switchport is in access mode and will only allow a single VLAN across it (with the exception of the voice VLAN). I think that is the real cause of your problem.
From what I can see, you have 2 options available to you:
1) Use dACLs instead of VLAN assignment. This means that an access list will be downloaded from the radius server straight to the authenticated user's session. I have tested this and it works perfectly. Just Google Cisco IBNS quick reference guide and look for the section that deals with Low Impact mode.
2) Get rid of the dumb switches and use managed switches throughout your network. Dumb switches will always be a point of weakness in your network because they have no intelligence to do advanced security features like port security, 802.1x, DHCP snooping, etc.
Hopefully someone else will chime in with another option.

SYS user connects at database level, is it correct?

My senior colleague has given me following information about the sys user. I want to know, is it correct?
Since SYS user connects at the database level, therefore, on killing the active session of the SYS user,only the current statement is cancelled. The database session does not disconnect. Instead it continues to run the remaining statements in the script file in case we are running a script file containing a lot of SQL statements.

Instead it continues to run the remaining statements in the script file in case we are running a script file containing a lot of SQL statements.Running a SQL script very likely means SQL*Plus is used. One of two types of Oracle sessions will be created via sqlplus. A dedicated session. Or a shared server session.
A dedicated session can also be local (sqlplus connects "directly" to the dedicated server process), or remote (sqlplus connects via tcp/ip to the dedicated server process).
A server session is usually "killed" using the alter system kill session command. Despite the differences between shared and dedicated server connections, the end result is the same. The session terminates abnormally (session UGA will be released, session will be cleaned up, rolled back, etc) - and the session ceases to exist.
So irrespective of how that sqlplus session runs that script - the session, when killed, will cause a sqlplus failure. And no subsequent script commands would be executed by that Oracle session.
What can happen is that sqlplus continues running, continues reading the script, and continues submitting commands to be executed. However, with the server session killed, there is no server process to service the commands submitted by the sqlplus client. In this case, sqlplus will throw the error "+SP2-0640: Not connected+" after each of the commands it tries to execute after the server session was killed.
The only time when sqlplus will be able to continue is when the session is not killed, but interrupted. The Oracle Call Interface (OCI) supports a OCIBreak() call - allowing the client to interrupt-and-abort the request that its server session is currently executing.
For example, sqlplus sends a OCIBreak() while it waits for a server response (e.g. waiting for the answer to a SQL select query), when the user presses Ctrl-Break to abort that request.
In this case, the session still exists - and the client can issue a new request that the session will service. But an OCIBreak() cannot be triggered (to my knowledge) externally from another Oracle session. You need to send the client process a "break request" (like a Ctrl-Break keystroke) in order to trigger that client process to make an OCIBreak() call to Oracle and interrupt its server process.

Max no. of users connections in essbase

Hi All,
How can i find what is the max. no. of users connections is allowed for essbase. If there is some setting in EAS console or we can define it through MAXL. We are using very old version (version 6- using ESSCMD commands). We have already provided access to about 475 users. 200 more users are waiting for access.
Thanks,
Anchit

Herewith the relevant parameter you can define in your ESSBASE.CFG - it should answer your question:
MAXLOGINS
Sets a limit on the number of user sessions that can be connected to the Essbase Server at any one time.
Syntax
MAXLOGINS n
n Any integer from 1000 to 1048575 is valid. The default value is 10000.
Description
This setting limits the maximum number of user sessions allowed to connect to the Essbase Server at any one time. This number includes multiple instances of the same user.
You may wish to adjust the value of MAXLOGINS to match computer resources, or to more closely manage concurrent ports and user sessions. A concurrent port is used for each unique combination of client machine, Essbase Server and login name. For example, the same user > with five open Excel worksheets connected to the same Essbase Server use one port, but five sessions.
Notes
Increasing the value of MAXLOGINS increases memory use approximately 6 bytes per user session.
If the setting is less than the minimum value, 1000, the value is assumed to be 1000.
Example
MAXLOGINS 50000
increases the maximum number of simultaneous logins possible, from the default of 10000 to 50000. > Kind regards

e.g. enable LOG_USERNAME to see the user that authenticated, and LOG_CONNECTION to see additional IP connection information.

2) How can I drop connection, diallow this user for time or manage this user connections? You could change the users password to stop them authenticating, or set their mailuserstatus: attribute to disabled and so forth.

Limiting the number of users/connections

We currently have a very large user community (120000)who will be accessing the portal for ESS/MSS functionality.
We would like to limit the number of users to around 20000. Any more connections should get a nice error message (rather than a standard IE no more connections or a time out message).
We can obviously throttle the number of connections via the load balancer or via max connections in unix. Is there any method in the Portal itself, that will automatically direct the users to a seperate web page in the event of pre determined number of users/connections being reached.
I have search high and low but can't find a solution.
Thanks in advance
Fenton

Hi Tim,
No, there is nothing like this as a standard functionality within the portal. Similar requests are regulary asked on SDN (like: restrict the number of users logging in as you ask, restrict the number of parallel logins of one user, and things like this).
A possibility would be to implement your own login module which tries to check how many users are online. All techniques - independent if on portal or on WAS side - that try to count this have the problem that they cannot be sure who is "online" as you have no definite information if a user is online or not; one can only use more or less heuristic methods.
Hope it helps

How does client connect to RAC

I'm confused how client connect to RAC,
1) According to this:
http://www.datadirect.com/developer/odbc/odbc_oracle_rac/connecting/index.ssp
"a ServiceName exists for the entire Oracle RAC system. When an application uses the Oracle RAC system's ServiceName, the Oracle RAC system appears to be a single Oracle instance to the application"
so, seems client just make sure using service name instead of SID, it will be connect to RAC. the URL format is same as single non-RAC enviroment
2) however,according to this:
http://forums.sun.com/thread.jspa?threadID=5274308
The URL need to be:
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service)))
this make RAC connect URL differenct from single non-RAC enviroment
if so, with this format, how does SQL developer connection set up? since you can only specify one host in connection properties configuration?
if so, adding a node will require all of client modify connect url?
3) my understanding is client only need to specify VIP to any one of node, and speicify global service name (all node should share same service name), this will make RAC connection setup (similar to above (1)), but I'm not sure if my understanding correct or not in the following senario:
-- a) what if client using public ip (not VIP) to one of node, but using global service name?
-- b) what if client using VIP to one of node, but using it's SID instead of global service name?
-- c) what if client using public ip (not VIP) to one of node, and using it's SID?
please clarify how does client connect to RAC?
Thank you!

Very good question.
You have asked in a certain way which tells me you have done lot of research.
Any how:-
Remember no matter how convoluting it looks it is the same.
1 Tns Entry
If you add a node then yes you have to publish it.
There are other alternatives such as Oracle Names [old]
internect directory , ldap and so on, beyond the scope of this discussion.
1)
TNSNAME Entry
RAC.WORLD=
DESCRIPTION=DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service))
Now see The same string from DESCRIPTION onwards goes to jdb thin client, it
is the same thing...
Also the host1 host2 are all VIPS'
Also you need failover , load balance thingies in there
-- a) what if client using public ip (not VIP) to one of node, but using global service name?
non vip, Test it out, tns should hop over it .
but TAF /FAN won't work.
-- b) what if client using VIP to one of node, but using it's SID instead of global service name?
You have to use SERVICENAME, if you are using SID then you are pretty
much connecting to 1 node.
-- c) what if client using public ip (not VIP) to one of node, and using it's SID?
Then you are using 1 node rac.

Script to Determine Users Connected to Oracle Apps and For Imitating Users

I found this great script (Note:430948.1 on Metalink) to track users connected to the E-Business Suite.
My colleague though noticed that users who had shut their browsers without logging off or those users who had 'timed out of their session' would still come back in the report.
He wanted an accurate measure of who was in fact using the e-Business suite.
We took the original query and added the last line (below). It basically takes the ‘last connect’ time and adds 60 minutes to it to figure out who is ‘validly’ still connected.
select distinct ic.disabled_flag, fu.user_name User_Name,fr.RESPONSIBILITY_KEY Responsibility, fu.user_name,fu.user_id, fu.description, fu.employee_id,
ic.responsibility_application_id, ic.responsibility_id, ic.org_id, ic.function_type, ic.counter, ic.first_connect, ic.last_connect,
ic.nls_territory, ic.time_out, fr.menu_id, fr.responsibility_key
from apps_fnd.fnd_user fu,
apps_fnd.fnd_responsibility fr, apps_fnd.icx_sessions ic
where fu.user_id = ic.user_id AND
fr.responsibility_id = ic.responsibility_id AND
ic.disabled_flag='N' AND
ic.responsibility_id is not null AND
ic.last_connect > sysdate - (ic.time_out/60)/96
Can anybody see any issues with this query? or a better way to do this?
It looks like Oracle runs a clean up script to wipe out sessions after a certain amount of time so they are no longer active sessions - so this works around that.

File sharing reports too many users connected

SPECS: Mac Mini Core 2 Duo 2 GHz, 2G RAM, Mac OS X 10.6.4. Other users in office also running similar hardware and Mac OS X 10.6.4.
CLARIFICATION: This Mini is used as a file server in a small law office (4 other workstations). It is running Mac OS X Client, not Server. I refer to the machine as "the server" but wanted to be clear the operating system is the same on all stations.
HISTORY & CONFIG: This system was setup in November 2009. It provides simple file sharing storage for a 4-user law office and runs Retrospect (version 8.1.626) to do some local and network backup operations. At the time it was setup, it was also running Now Up-to-Date Server but that program is no longer supported, and it has been removed from the computer (May 31, 2010). In late March 2010, I installed Daylite Server as a replacement for Now Up-to-Date. All stations are running Mac OS X 10.6.4, and have always been at the most recent Mac OS X 10.6.x revision within a few days of the release of a major update.
PROBLEM: Occasionally, clients cannot connect to the server (and I don't have the exact error message -- next time it happens, someone is supposed to get a screenshot). When this happens, if you go to the server and open the file sharing control panel, then click "options", you will see an impossible number of people are connected. The first time this happened was on April 28, 2010, when it reported 41 users were connected. Mac OS X Client has an upper limit of 10 simultaneous user connections, so you can see this number is not possible. Additionally, these are "phantom" logins because you can execute this command in Terminal to see the IP addresses of any connected users:
netstat -n | grep '.548'
And when I do this, unless there was someone who had logged in prior to the "phantom explosion", it never shows any connections. On two occasions, I've actually been in the office late one night to do maintenance, checked the server before I left and found 0 connected users, then got a call in the morning that the first person who attempted to connect was blocked and the server showed 10 or more users connected.
I do not believe this is some kind of security breach. The server is not Internet-accessible, and as is shown by the netstat command, there really isn't anyone logged in anyway. I consulted with Marketcircle (makers of Daylite) because it seemed very coincidental that I installed their software just prior to the beginning of this problem, but they claim Daylite does not make any use of the Mac file sharing system. But, again, since these aren't real users, I suppose it's possible a bug in their software is somehow upping the Mac's connected user count erroneously?
Restarting the server always fixes the problem -- until it happens again. This Mac Mini is a pretty simple station -- just runs Daylite Server and Retrospect Single Server, plus the basic file sharing. Anyone have any ideas why this keeps happening?

I would say odds are likely this is correct. On at least two occasions I can think of where I verified everything was okay and later discovered a "phantom explosion", a Retrospect backup would have run. Our backups typically run at 3 AM. Is this a known issue with Retrospect? If so... not sure why it doesn't happen all the time. And in my own office I have a pretty similar setup on an entirely different computer that multiple people connect to, and it never does this. Color me confused.
