What limits the number of MII connections to Oracle.

We are using MII 12.0.5 and an Oracle database and are seeing errors in the logs to the effect:
SQL error occurred on connection jdbc:oracle:thin:@mii001:1527:SMD: code=0, state="null", message="Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
The Connection descriptor used by the client was:
mii001:1527:SMD
I am ot an Oracle expert and I have not seen this issue before. What is limiting the number of connections? Is this a MII configuration issue that I am not aware of or an Oracle database issue?

Hello sparks,
I assume you are getting this error when you are trying to connect to databse while configuring Dataservers in MII,if fo what are the value you passed in the fields PoolMax and PoolSize while connecting to the database.

Kumar

How to find the number of ODBC connections to Oracle Database

Hi All,
How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
Thanks in advance,
Mahi

What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
For example: if you already know of a user using ODBC, you can verify as:
select username, osuser, terminal, program from v$session where username = 'SCOTT'
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
Hope this helps...

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

Getting the number of active connections in a connection Pool

Hi,
I have an application deployed on jboss. DB used is db2. For monitoring purpose i need to get the number of active and idle connections at any point of time. I am trying to use commons-dbcp jar to get this data using BasicDataSourceClass. Following is the piece of code.
Context initialContext;
try {
     initialContext = new InitialContext();
     DataSource ds = (DataSource) initialContext.lookup(myjndiname);
     logger.info("************CONNECTION POOL DATA->" + ds.getClass().getName() + "************" + ds.getClass() + "**************");
     BasicDataSource bds = (BasicDataSource) datasource;
          logger.info("************CONNECTION POOL DATA-> ACTIVE CONN=" + bds.getNumActive() + " IDLE CONN=" + bds.getNumIdle() + " INIT SIZE=" + bds.getInitialSize());
catch (NamingException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
This code gave a class cast exception at the point datasource is cast to BasicDataSource. The class name returned by ds is WrapperDataSource. I have few queries on this:-
1. What configurations do i need so that datasource returned by InitialContext is BasicDataSource? FYI i tried to add the BasicDataSourceFactory in db2-ds.xml. But it still didnt work
2. Is there any other way to find the number of active connections in a connection pool? I dont want any server specific solution.
Pls help.
Thanks

What is the best way to connect my guitar to the usb port on my IMac

This is for use with Logic Pro X
what is the best way to connect my guitar to the usb port on my
I-Mac

As has been said really, the less you pay the less quality, and flexibility you'll have on your sound.
For example, you could run on a 'Rocksmith Real Tone Cable' if you just wanted a cheap way of getting your guitar into the computer for some fun. Probably cost you $30 (I live in UK so can't be sure). If you're starting out then this could be considered the best option for dipping your toe in the water without spending too much.
You won't get a really nasty sound out of that if you can process it yourself in Logic afterwards to clean up, but it won't be great either. I imagine it could get quite noisy so you'd need to get heavily gating your guitar sound, if you're playing something clean that's not ideal.
Longterm, you're far better getting a decent audio interface, as you need something to play sound back through, if you have different input sources you usually have to create an aggregrate device on osx to use multple sources at once esp if you're using the built in audio chip on your mac to listen.
All this can add latency and possibly sync issues (i.e. drum tracks not in time with audio etc.), although generally it's not too bad, but it's something worth knowing if you want to do things on the cheap without buying a dedicated interface.
What kind of money did you want to spend? Are you thinking super duper cheap, and then see how it goes and maybe spend more in future if you enjoy it? Personally i would say £100-150 would get your something good to start with, like that Presonus audiobox, there's a lot of options like that available.
My local music shop always push the alesis io2 on new users, gotta say i'm not that overly impressed with it. Line 6 stuff will be good however, but limiting. Although i beleive you get their software for free with it?

How to limit the number of TCP connections beeing used concurrently while a page is beeing loaded?

We manufacture industrial small-footprint control modules with embedded web server. The resources of these modules are very limited, especially in RAM. We have problem, that FF opens 15 parallel TCP connections while loading a web page (main html page first, then all icons simultaneously). We can not handle such behavior because of lack of RAM memory needed for TCP buffers.
Question is how to limit the number of concurrent TCP connections the browser will use? We need to do it somehow directly from the page, we can not push our customers to change the general settings of their browsers (they would not understand such things anyway).
Do anyone have any suggestion?

Sorry, one other thought. Many web designers now combine all icons into a single image and use CSS to clip the image so that only the desired portion is displayed. This minimizes the number of required connections and increases the probability that the image can be retrieved from cache.

Adobe Media Server pro 5 Scalabiltiy Requirements with respect to the number of clients connected

what are the hardware requirements mapped to the number of clients connected to a vritual server running on a Windows 2008 R2 Server? At what point should the scaling be done, what are the best practices? The encoding rate used is 360 Kbps.

Hi Simon
The HTTP (HDS and HLS) streaming and recording limit in Adobe Media Server 5 Starter is 10 min. You'll need to buy a serial key if you want to record/stream for longer. Also there are no limit on number of clients for HTTP.
Hope this helps.

Weird outbound problem = The number of vod connections are: 0

Hi all - I am a Verizon Fios BUSINESS customer, but their technical support has been of no help with this issue as I think I understand their routers better than they do.
I work from home in the Video Conferencing industry. I recently had trouble in my area that resulted in VZ replacing my older Actiontec router with a shiny new red one with the n speed wireless (MI424WR-GEN3I). Since that router was replaced I've been unable to initiate video recordings FROM my hardware video system in my office to my recording server on the internet. I had no problems whatsoever with the old router.
These recordings are initiated on port 443 and 554 TCP and then some high level UDP ports. It fails on my system and the message I get in the security log on the Actiontec is "The number of vod connections are: 0". Now, it's using RTSP (real-time streaming protocol) which perhaps the router thinks is video on demand and says that is a no-no? I don't know.
At this point I've tried everything - port forwarding, advanced filtering opening all IP between my VC system and the recorder - I even changed the remote administration from port 443 to 4430 because of something else I read. I can record locally no problem to a machine here on my LAN.
Lastly, I downgraded to the previous version of firmware just for kicks but no joy. Does anyone have ANY idea what the heck is going on?

I am sorry to hear about the problems you are having with your service since getting the new router. To see if it's router firewall issue, true putting the computer in the DMZ zone briefly to test. If it works in the DMZ, then we know it's a portforwarding issue.

DB2 Connect version 8.2 is no longer supported by IBM (support ended April 30, 2009, see http://www.ibm.com/software/data/support/lifecycle/). As far as I know, DB2 Connect is communicating through DRDA, which is a platform-independent protocol supported by all DB2 platforms, so any DB2 Connect client should be able to talk to any DB2 database. However, there may be limitations on the supported release combinations.
Kind regards,
Christian Bartels.

Server Administrator has Limited the Number of Items You Can Open Simultaneously

Over the weekend, we moved all of our room mailboxes over to Exchange. For users who have lots of room calendars open in their Outlook clients, they are getting the error message "Cannot Open the free/busy information. You Server Administrator has Limited
the Number of Items You Can Open Simultaneously" after the migration from Exchange 2010.
Restarting the Outlook client temporary fixes the problem, but the problem comes back after they access the calendars again.
The users impacted deal with a lot of room scheduling, so they have 30+ room calendars open in their Outlook clients.
I have tried setting up a throttling policy with unlimited RCA connections, but that didn't help.
I have seen with Exchange 2010 there were some registry keys people were setting on the server that pretty much makes everybody have unlimited connections, but that isn't ideal if's only affecting a few people.

Hi,
Since this issue only occurs to a few users, I recommend you disable all the third-party applications on Windows, especially for the desktop search apps. Meanwhile, use Outlook safe mode to disable all the add-ins and check if the issue persists.
If the issue persists, you need to reset the value of Maximum Allowed Sessions Per User. Besides, we can't set it for only some specified users.
Here is a thread for your reference.
Event 9646, MSExchangeIS - Mapi session exceeded the maximum (Note: Though it is Exchange 2010, it also applies to Exchange 2013 about this issue)

What is the correct adapter to connect my Macbook pro with mini-dvi to my TV with Scart

I have a MacBook Pro with mini-DVI and I want to connect it to my TV which has only a scart thing.
Can I use the mini-DVI to Video-Adapter and then a Video to Scart-Adapter?
Thanks for your help!

So of course you've corrected the title : "What is the right PLUG to connect my macbook pro to my TV ?"
OK so a bit more info : my TV is a Sony Trinitron TV.
It has the yellow/red/white plugs. I don't believe it has anything more sophisticated or recent than that.
Thanks for your help !

What is the number for Verizon Wireless Corporate Customer Service Complaint for CA

My Complaint: I have been a Verizon Wireless customer for approx 20 years. I called customer service to seek an early upgrade for my daughter's phone. She is away in college and her phone is malfunctioning. She is eligible for an upgrade in approx 6 weeks so I did not want to spend the money on a replacement phone when since we were planning on updating to something newer. The customer service rep to me they could not do the early upgrade an to call back in a few weeks. After explaining this was unacceptable (I do not like the idea of a young female being out of state and away from home with no reliable means of communication), she places me on hold to later return with the only offer of I must purchase a new device through her ( over the phone) which will be shipped to me, the phone was priced $100.00 more than the online price (they will not price match), plus i must pay $30.00 upgrade fee, $35.00 activation fee and taxes on the retail price of the phone. I am upset and disappointed with the quality of service provided by Verizon being a 20 year customer. If not for the seriousness and urgency of this matter, i would not have asked for an early upgrade. It is times such as these that you get to see how much of a "valued customer" you really are. I guess you are valued as long as you pay your bill and continually purchase their products. I would like to speak with someone from Verizon's corporate or customer relations department. As of now I am really considering changing my service to a different provider. I have multiple accounts with Verizon and i will canx each after the current contract committment expire (starting with my daughter's phone which expires in 6 weeks) In the meantime I will go purchase her a new phone with someone else and take comfort knowing she will have reliable communication.

I started with them in 1985. It has been wonderful service but very expensive. They seem to operate on day of deposit day of withdrawal. That means that I have no benefits nothing beyond the normal customer if I don't pay my bill they shut me off. That's why I have switch to another provider and I have better service lower cost and better phones. you can't beat other providers I mean it. Please don't expect more from verizon other than a "pay me more money and I'll do what you want" because it's all about money. Read the transcripts from current Verizon employees all over the internet. The company is going down and they're taking customers with them.
