Cross connection

Hi
everyone
I have installed oracle database 11g on my pc and recently installed oracle developer suite 10g
I am unable to connect to my database using oracle developer suite It's giving an error that
"ORA-12154:TNS could not resolve the connect identifier specified"
How to solve this problem or can't we connect to database using older version of suite
Kindly answer me this question as soon as possible
Thanks,

Do you configure <DevSuiteHome_1>\network\admin\tnsnames.ora
to connect with database ? If no.
Copy the connect identifier from <database path >\network\admin\tnsnames.ora to <DevSuiteHome_1>\network\admin\tnsnames.ora
and try.
Hope this helps
Hamid

  • Sun Cluster & 6130/6140 thru switch with cross-connections not supported?

    Hi:
    I noticed that the 6140 does not support cross-connecting the 2 controllers to 2 switches for higher availability when using Sun Cluster:
    http://docs.sun.com/source/819-7497-10/chapter3.html
    Does anyone know why this restriction is there?
    Thanks!

    Since there was no real answer to the question in this forum, I cross posted this issue to the cluster forum.
    See http://forum.java.sun.com/thread.jspa?threadID=5261282&tstart=0 for the full thread.
    Basically, the restriction against cross-connections is no longer valid and the documentation should be updated to remove the note.
    This is all a good thing, because I had my 6140's wired into my sun cluster environment via the 'cross-connections' method diagramed in figure 3-4. :-)

  • Cisco 3020 internal cross-connect

    Hey, network professionals!
    I found the following text about the Cisco 3020 switch:
    Dual-purpose external/internal 10/100/1000BASE-T copper Gigabit Ethernet uplink ports. These
    ports can be configured for internal 1000BASE-X cross-connection with a corresponding switch
    module. When ports 23x and 24x are in external operation mode, they support auto-MDIX and
    autonegotiation. The default is external operation mode.
    But how exactly are the internal connections between my 6 cisco 3020 switches in the c7000 HP Blade enclosure ?
    What does "corresponding switch module" means ?
    Thank you
    Constantin

    I have to say yes, it can since the concentrator can be defined as a hub for vpn traffic, in here I will ask you a question. Do the devices on the "outside" meaning on the public side of the concentrator know how to reach the vpn client? In other words do these devices have a route back to the concetrator to reach the vpn client's pool?

  • Bypass(IPS or TAP) network cross-connect the two RJ45 connectors electrically thus creating an extended Layer 1 network

     Thanks for your time and knowledge. I am trying to understand how bypass mode works in terms of cross connection. 
     Bypass mode:  network relays cross-connect the two RJ45 connectors electrically thus creating an extended Layer 1 network
     Let us focus on one connection  COM1 ---  3560 ---  ELFIQ (Link Balancer) ---- ASA. 
     Basically ELFIQ will be a bypass mode when power is gone. 
     The engineer told me that I have to put cross cable between ELFIQ and ASA5505 only which is "2" cable from below diagram. 
     So, it will be 
     COM1 ------(Straight)-----  3560 -----(straight)------  ELFIQ (Link Balancer) -----(cross)--- ASA.
     And he told me also that if there is no switch (in future). I need to put both cables as cross cables. 
     COM1 ------------- (Cross) ------------------ ELFIQ-------------- (Cross) ------------------ ASA5505
     I couldn't see any consistency from this bypass works because case 1 (with switch) and case 2 (without switch) 
     Is my understanding right like below? 
     case 1: straight - straight - cross : cross
     case 2: cross - cross: straight.

  • Cross Connection Detected - Pipex DSL

    I've recently had the mis-pleasure of having to re-install and archive my iMac G5 back to OSX 10.3.5 (was running on 10.3.9), as I was getting a blank grey screen on start-up, which I'm still at a loss as to why my iMac suddenly stopped working after two years of iMac joy.
    Unfortunately, I didn't tick the box to keep all my user settings, [doh!], and have had to re-install and re-configure my dsl settings to connect to my isp Pipex.
    I've followed their support instructions as detailed on their website to the below settings:
    Location: Automatic
    Show: Speedtouch USB
    PPP
    Service Provider: Pipex Xtreme
    Account Name [email protected] (my username)
    Password: .......
    Telephone Number: 0,38
    I've re-installed the Alcatel Speedtouch modem software, and the iMac recognises the modem, when it's plugged into any of the USB ports.
    When I try and connect to the service, I get the message
    "A cross connection has been detected, please verify your settings and try again", which I have done countless times.
    I know my Pipex service is ok, as it works fine on my PC, from where I type this now.
    I've left it several days, I've re-booted countless times.
    Does anyone know what else I need to do?
    I've emailed Pipex, in the hope their support team can help, but thought I'd try here as well.
    What causes the above error?
    Any suggestions would be much appreciated!

    I am having exactly the same issues aswell and looking at the posts there was no end to the problem with the product working.  Can anyone shed some insight as I have tried all the same steps but to no avail.... the status tab gives me no IP/gateway/DNS information -
     Connection Type: Automatic Configuration - DHCP     Internet IP Address: 0.0.0.0     Subnet Mask: 0.0.0.0     Default Gateway: 0.0.0.0  
    if i try and ping an IP address from my machine or using digits when connected direct to modem then I get correct response but when using the router with wired connection then it cannot find IP addresses and  times out...

  • Do mutiple 6120 cross-connect (heartbeat) work through a switch?

    We have two 6120s connected to two UCS 5108s in two separate rooms in our building.  We have just completed a 2nd formal server room and will be moving one of the 6120/5108 pairs into that room.  Currently, the 6120's are cross connected (1Gig copper) to each other and all of the 10Gig connections are appropriately connected.
    The issue is that the two server rooms are more than 100m apart so there is no copper connections between the rooms.  We have switches in each room connected via 10Gig fiber.
    Our VAR who installed originally this sent an e-mail that these 1Gig copper cross connects must not pass through a switch.  He has left to get married and is gone for a few weeks.
    We are not moving this until November, but I'm not willing to wait a couple of weeks until the engineer returns to get the answer to this question.  I have looked on CCO and other than identifying the 1Gig ports as "cross-connect" or "cluster", I can't find anything out.
    I would think that they would work through a switch, perhaps in their own non-routed VLAN or something.
    Will this work?  Is there a design guide on CCO that shows it?
    Thanks!

    What you are asking for is an enhancement which I fully agree with.
    Latency is not the issue here. It is how the software which manages the L1-L2 links on the FI's.
    They are bonded internally. Not expecting any other traffic (CDP, BPDU or anything else when you connect to a switch for example amongst other things). You connect a switch in between and bonding breaks. You could now potentially think of 1 link to get around bonding or turn channel-group explicitly on the switch etc..
    But the fact of the matter is that it has neither been tested/blessed nor advertised as a possible workaround.
    So currently it won't work and *if* it does, you are in unchartered territory where support if something breaks is going to be an issue.
    If you look at the User Guide at
    http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/b_GUI_Config_Guide.html
    Page 63 and 65 have references to it -
    The L1 ports on both fabric interconnects are directly connected to each other.
    The L2 ports on both fabric interconnects are directly connected to each other.
    To use the cluster configuration,the two fabric interconnects must be directly connected together using Ethernet cables between the L1 (L1-to-L1) and L2 (L2-to-L2) high availability ports,with no other fabric interconnects in between.
    Note: I would have written  "with no other *switches* in between" rather than fabric interconnect above but then thats me.
    The 10 Gig links cannot be used for heartbeat either. All mgmt is the 4 1 gig ports that you see on the FI's. 10gig's are data.
    Sorry to be the bearer of the bad news

  • Powerbook G4 with RAZR V3 as modem crossed connections error

    I'm having what seems to be a very simple problem trying to use my phone as a modem. Unfortunately my new apartment isn't wired for cable or a landline, so I thought this would be the easiest option for Internet. Think again! I've been trying to reach T Mobile for 2 days, and have been left on hold for up to two hours. Finally they told me that the problem is with my Mac software and not the phone.
    Basically the problem is this. When I try to dial up with my bluetooth (I have all the settings correct, I believe, plus the T Mobile password/number in place) it connects, and then immediately disconnects giving an error of:
    "A crossed connection was detected. Please check your settings and try again."
    I am at my wit's end and don't know what to do. My computer is about 2 years old - I don't know what version of OSX I have, because as you've seen, I have to send this message from work since I don't have Internet at home.
    Is there a software update for bluetooth I should install? As far as I know I'm more or less up to date on my updates.
    Thank you!!!!
    Powerbook G4   Mac OS X (10.0.x)   bluetooth

    Welcome to Apple Discussions.
    They are right: this is an issue on your end involving your configuration. It involves the use of an inappropriate modem driver. Your Motorola RAZR V3 is a GPRS modem when connected to your computer using the Bluetooth dial-up networking [DUN] profile, and requires an appropriate modem script, account settings specific to your carrier, and a data plan.
    If you are a T-Mobile subscriber with T-Mobile Unlimited Internet, you have the required data plan. Your Internet Connect settings should be:
    Telephone number: *99#
    Account name: voicestream
    Password: voicestream
    The APN identifier is internet2.voicestream.com for standard connections and internet3.voicestream.com for virtual private networking connections. Which you are configure to use depends upon your prior communication with T-Mobile data specialists, but the default is the non-VPN internet2.voicestream.com identifier.
    You can locate a GPRS script at Ross Barkman's site at…
    http://www.taniwha.org.uk
    …or purchase Macron's GPRS Script Generator to create and fine-tune your own. More information about the Macron product is available here:

  • Cross connected calls over MPLS WAN

    Hi,
    I have an issue with one of my offices that has me extremely puzzled.
    When users call users in other offices, sometimes the calls get cross-connected, where they are suddenly talking to another caller.
    Our telephony provider is insisting it is my network, but I have this office router and switches configured the same as our other 5 offices that don't have this issue.
    They are now trying to say it is an MPLS issue from our Telco, but I figure I would be seeing issues with data going over that link as well.
    Has anyone ever experience this "crosstalk" before?
    The routers at the offices are 2811/2851, with 10meg MPLS WAN between, and 3560/3750 PoE switches for the phones.
    Any advice or tips would be greatly appreciated!

    The 2851 at our head office is running 12.3(8)T8.
    The 2821 at the remote office is running 12.3(8)T8 as well.
    We are not using CCM, we are using a Mitel VoIP solution (which I hate and wanted to go with Cisco instead!), which is using Minet (shows as RTP traffic).

  • Cross connecting 3750 stacks

    I'm new to Cisco switches.
    I need to connect two 3750G stacks. One stack consists of 3 x 3750G-48PS and 2nd stack is 3 x 3750G-24TS. Since all switches have 4 SFP ports I would like to use them to create 3 3Gb etherchannels in a full mesh and redundancy.
    stack1 Gi1/0/49 - stack2 Gi1/0/25
    stack1 Gi1/0/50 - stack2 Gi2/0/25
    stack1 Gi1/0/51 - stack2 Gi3/0/25
    stack1 Gi2/0/49 - stack2 Gi1/0/26
    stack1 Gi2/0/50 - stack2 Gi2/0/26
    stack1 Gi2/0/51 - stack2 Gi3/0/26
    stack1 Gi3/0/49 - stack2 Gi1/0/27
    stack1 Gi3/0/50 - stack2 Gi2/0/27
    stack1 Gi3/0/51 - stack2 Gi3/0/27
    Is this overkill or am I headed in a right direction? I have only the default VLAN so I understand that only one etherchannel is used for cross stack connection. Will this achieve auto failover?
    Fred

    Not sure what you mean by "if we brought down the switch hosting it" , if you mean one switch in the stack then you would not lose your connection . The etherchannel would consist of one connection out of each switch in the stack on one etherchannel , the data would continue to flow over the other 2 links in the etherchannel. If you have one etherchannel consisting of one connection out out of each switch in the stack then you have 3 redundant gigbit connections , highly unlikely you would lose all 3 and this simplifies the config by only having one ehterchannel and saves money by not having to buy so many sfp gbics.

  • Reporting Services in SCCM Console (Cross Connect)

    Hi,
    we have a cas - primary site setup and have a reporting point on our cas server.
    when connecting to the cas server with the sccm console from a client i see all reports and all is fine.
    when connecting to the primary site server and type in the cas server in the reporting services pane i see no reports.
    i thought that's possible. i can open the .../reportserver website with the client of course.
    thx
    steffen

    Since no one has answer this post, I recommend opening  a support case with CSS as they can work with you to solve this problem.

  • SQL Server/Client Version cross connectivity or in other words, connecting from one version of an SQL client to another version of an SQL server.

    I wasn't sure, so I'm posting this question to understand better.  If I have an SQL Server on SQL 2005 and a client running SQL 2000, can that client talk to the server?  Also, if I had the opposite, a Server on SQL 2000 and a client on SQL 2005, is communication possible? 
    Thanks for the SQL help!

    From my experience, a newer client with an older server cannot use a new data type either. I tried this with a SQL Server 2008 R2 client against a database on a SQL Server 2000 instance.
    declare @myDate1 date
    Result...
    Msg 2715, Level 16, State 3, Line 1
    Column or parameter #-1: Cannot find data type date.
    Parameter '@myDate1' has an invalid data type.

    i have posted more on this here
    BRIDGE command in Oracle SQL Developer - Stack Overflow
    i would be most grateful for any help

    Hi Smachin,
    Thanks for the heads up.
    Its busted due to a change in how SQL Developer loads components. BRIDGE being a migration component, it doesn't load until a migration action is performed (like Copy to Oracle or opening the Translation Scratch Editor).
    Quick workaround: Start SQL Developer, Tools > Migration  > Scratch Editor. Now when you open a worksheet the BRIDGE command will be recognized.
    Note I think there was some work recently on BRIDGE so SQL Dev 4 EA2 should be used.
    Ill work making BRIDGE work without having to do anything special.
    Thanks,

  • Sun cluster, 6140 and 'cross-connections'

    This was brought up in the storage forum by somebody else, but the responses never answered the original question:
    In the 6140 setup document located at http://docs.sun.com/source/819-7497-11/chapter3.html#50589714_93886 it shows two different ways to cable a host to a 6140 via a SAN switch. figure 3-3 and 3-4
    It states that the setup in 3-4 is not supported in a sun cluster environment.
    The problem is that given the acive/passive nature of the 6140, the setup shown in 3-4 is the obvious one to use since it prevents one from having to force all of the luns over in the event of an hba port or switch failure.
    To make life more interesting, the 6140 setup doc does not make not of what version of sun cluster it is not supported on. Or what the bugid is, or any informationto know if the restriction is still valid.
    So, does this restriction still exist? If so, for what version of sun cluster? What version of solaris?

    Thanks for the clarification.
    As an aside, it would be nice if in the future, the documentation could contain a bit more information than just a simple note saying 'this is not supported'. A reference to a bugid or info doc would go a long way in helping folks determine if the restriction is still valid.

  • How do I use my ethernet connection for printing on my LAN and use my Wifi on a different router and ISP to connect to the internet?

    I'm in a small office, and I have to use my ethernet connection to connect to the networked copier to be able to print, but connection to which I hooked my Time Capsule is literally 20x faster when connecting to the internet.
    How can I tell the computer to use the ethernet connection to print, while everything else should go through wifi?
    I have been manually going back and forth changing the order in Network Preferences between ethernet and Wifi, but I'm know there must be an easier way.  Thanks for your help!

    A packet going to Apple is not local. It is going to 17.149.160.49  -- So it is sent to the topmost working connection to be Routed and sent to the Internet.
    A packet going to a local computer or other device that is on the same subnet (has an IP address very close to the topmost IP Address of your computer) gets sent out that port as well, but is sent directly to that computer on the local subnet, since no Routing [changing of Addresses} is needed.
    A packet going to a local computer or Printer or Network Attached Storage device that is not on the topmost subnet, but is on a secondary subnet such as the second network connection would be sent directly to that computer, since no Routing is needed.
    I do not understand why two Routers have the same IP Address if they are not cross-connected. That makes everything very difficult when it should be simple.
