Number of connections limited to 5 users / ips...

is there a way around this? i have to reboot to clear this up!
why doesn't weblogic server release ips once user logs out or once ip not in
use anymore?
-- p

Hi
Note this is not meant to circumvent the license,
but one way around this is to add a Reverse Proxy like Apache/IIS in front of weblogic(and use the BEA plugin). The weblogic server then only see's one IP.

Limiting Number of connections from a single user

Hi ,
I am using 9.2.0.6 DB, i need to restrict the number of connections from a single user to 100.
Currently the user is having DEFAULT profile, this profile is having several other users associated to it.
What are all the available options to create restriction for a single user.
Create a new profile and add the user to the New profile is the option i have.
In that case can i create a copy of the Default profile and changing the SESSIONS_PER_USER to 100? will it work.
Appreciate your suggestion.
Thanks,
Sathis

Hi,
Since it is a default profile you can just create a new profile with the resource type you are interested it.
And if you want to copy the existing profile extract its ddl through below command, change the profile name and required resource and run against the db.
select dbms_metadata.get_ddl('PROFILE','<Profile_name>') from dual;Regards

Maximum Number of Connected Wireless Users?

I was reading a wireless document that shows a design where 3 WAPs on a 802.11b/g network for 180 users.
Best practices talk about 15 to 20 users per Access Point, which is what we typically do anyway.
So, my question is can the Cisco 1230 or 1240 Access Points (as an example) support like 50 to 60 users per Access Point within range?
I understand that the WAP wireless network is a shared (like a hub) network thus bandwidth is shared among all connected wireless users.
So, understand those considerations, but I want to know if those Access Points can actually support that number of connected wireless users or if there is a maximum number of associated users?
Thank you!

The theoretical maximum is 2048. As part of 802.11, however, some number of
these 2k addresses are reserved bringing the IEEE maximum down to 2007.
Although the AP motherboard has memory capable of handling 2007 users, the
radio utilized in our 1200 Series AP has memory limitations which hold the
maximum number of client associations to 255.
The number of 255 is active associations, though the cam table can
contain 2048 entries because of the memory size, the number restricted
for actual active association is 255.This number is still far too large for sensible
networking but what is possible. Remember that WLAN is shared media, all users have to try
to get access to the media by waiting until it is free and then sending a request to
reserve the media for the duration of the frame size that they want to
send. If the air is busy then you have to wait a random time and start
again. So if you have too many users waiting they can end up waiting a
very long time - sort of traffic jam effect at a congested junction, one
more car and the traffic seems n times worse.I dont know as to how the number 255 was
arrived at but it is largely irrelevant as 255 is still too large to be practical for
active associations, we recommend 25-30 for most design work.

Number of connection to this computer limited and all connections are in use right now

I have Lenovo ThinkPad T520 (i7, NVIDIA 4200TM) with dock station and two monitors. Sometimes when I close notebook and undock it from dock station. Then I cannot login to my notebook because of error "Number of connection to this computer limited and
all connections are in use right now". This is screenshot of my laptop http://i.imgur.com/6MXnQKf.jpg
Laptop is not in domain and does not have remote desktop connections. It was just turned in sleep mode and late turned on.
This happen pretty often one from 10..20 times of undock. It did not happen with Windows 7 before.

The network does not work properly after you resume the computer. This kind of issues are cuased by the network device driver. Download the latess Windows 8 driver from Lenovo website and install it.

Query: The number of connections possible on APEX

Hi all,
Hope you all are doing good.
there is one query,
Does the number of connections to apex depends on database memory ???
Is there any limitation on number of connections at the same time ?
i have one application,
APEX 4.1
DB 11.2.0.2
when it was launched.., people tried to login and as soon as they logged in the poratl/application went down. had to bounce the DB to get it back.
was clueless on what would be the reason for this behavior.
how do i make sure this would not occur again..,
thanks and regards,
Littlefoot

Hi Dietmar,
i have the same assumption, but the problem here the user is facing is, they have used some java scripts to upload the excel sheet and when uploading it the apex portal goes down.
they are still testing it, expected user to login is around 600 at the same time.

Actiontech MRI424WS number of connections possible?

I have the actiontech router for my Verizon FiOS and several items that need to be connected to it from my xboxes, PS3 laptops and mobile devices. I foudn a setting in the FiOS router that states "number of connections" and goes from 1 to 10.
The question I have is that from time to time one of our laptops seems to never be able to connect to the internet (Vista shows local access only). Is this because I have too many items on the router?  Is there a way around this limitation. If I had know this I would never have signed up for this.
Is the only way around this to buy another router and hook it in sequence to the actiontech?
Thanks for your responses.

Hubrisnxs wrote:
where exactly do you see that?   like on what page or after clicking what items in the router?
the router actually supports upto 254 some odd connections.
physically out of the box 4 hardwired connections and any number of wireless that fit within that configuration.
The screen you are looking at MIGHT be the number of pc's that can be logged into the verizon interface at one time, and not the amount of active connections.
Wow, that's a little scary. I have a Westell 9100Em and I currently show
Connections Active Connections: 258 Approximate Max. Connections: 154000
We must be talking a different connections page, there can't really be that difference between the 2 routers can there?
I accessed the connections screen by following the router users guide
I currently have 14 devices connected

If you select Firewall Settings in the top navigation menu and then select Connections in the left submenu, the

Number of connections made to database at a given time

Hello,
I would like to know the number the history and current number of connections made to the database via oracle application server at a given time. I see Active Connection when I click on HTTP Server, but I am not sure what that means. Does that mean the number of users on the site or does it mean the number of connections made to the database?
Also is there a way to find out the history of connections? Also is there a log file that all this information is recorded into?
Thanks for your help in advance.

Hi
Active Connections in HTTP Server -> Number of users connected to your site (active + inactive)
You can get information about database connections in v$session, or , in Enterprise manager -> OC4J container -> Home
If you are using datasources at application level you can get information about pooling in
Entreprise Manager -> 0C4J Container -> Application (select application ) -> DataSources
If you have datasources at OC4J container level you can get info in Entreprise Manager -> OC4J container -> Administration -> datasources

How to find out number of connections to database?

Hi,
How can I find number of connections connected to the database 4 hours ago. For examply, if current time is 5PM and I want to see total number of connections connected to database (and from what user?) in between 1 and 2 PM, is there a way to find that out?
I see v$session has a column MACHINE from which I can use count function to check the # of concurrent connections but I am not sure how to check the # of connections that happend few hours ago. Any suggestions?

you should have audit on .. and create logon trigger and make entry in the tabe ..that would give you .

Connection limits questions.

Hi all.
i got a crahed 5520 this week and was showing
<163>Nov 28 2011 11:34:45: %ASA-3-201013: Per-client connection limit exceeded -125/100
What the negative number tells ? i usually see same numbers like 100/100 with means the connection limited has reached.
also the box was showing
<163>Nov 28 2011 19:51:17: %ASA-3-210007: LU allocate xlate failed
<161>Nov 28 2011 17:50:44: %ASA-1-105005: (Primary) Lost Failover communications with mate on interface OUTSIDE
from the last 2 log messages its showing that the box was out of resources correct ?
Thanks.

The negative numbers reading is caused by a bug. Please see "CSCtl23397 - ASA may log negative values for Per-client conn limit exceeded messg".
The 210007 message is indicating stateful failover is out of resources. See this explanation.
Overall it appears your boxes may be pushing the limit of their capabilities connection-wise. Some further investigation would be required to determine whether that was a one-time event or indicative of a need to upgrade (memory or device).

Proxy Authorization with COS connection limits Issue

Any one having issues with connection limits (nsSizeLimit, nsTimeLimit, etc) be applied on connections that come from the proxy server with the proxy authorization control?
Example:
nsSizeLimit is set on user A to 2000, via a COS Pointer definition. If user A connects directly to the directory the nsSizeLimit of 2000 is used. If user A connects through the proxy, and the proxy connection to the directory is through a proxy authorization connection via ID admin1, the limit is not applied and the system default limit 1000 is applied.
If I over-ride the COS value for nsSizeLimit and say its 3000. If I use the proxy connection in this case the limit of 3000 is used. So it only fails for COS settings.
All the ACI's are being correctly applied via the proxy connection just not the connection limits. So basically I can't get the limits to work when I have a COS value being used via the proxy authorization user.
Any ideas on how I can get around this. I want to avoid having to enter in the different limits into entries. Also using the limits in the proxy would create to many connection handlers.
Thanks for any help you can give.
Cory

Hi,
I don't think that connection limits (Time, Size and Throughput) for User A can apply to operations that are using the Proxy Authorization for that user. Proxy Authz is a delegation of Authorization for the ACI, and does not apply to Connection specific limits.
Regards,
Ludovic.
