Mutual PORT convention for series components connected to a subcircuit EM structure

there exist an example in MWO for "Axiem_Mutual Ports". given a schematic layout, you can define your edge ports for series components as mutual group. so it is pretty straightforward.
however, in some instances where you need to include an EM structure as a subcircuit in the schematic and you want to connect a component to this EM structure. the question is how do you properly set up the Mutual port group naming for your component? this is because there is nothing to connect to for the 2nd PORT of the mutual group...an illustrative example is attached...

Not sure what you mean.  You have 2 ports with different numbers in the EM structure.  When the EM structure is placed in a circuit schematic as a subcircuit, it should have 2 ports, even if they are de-embedded mutually in the EM structure.  Your picture looks like a circuit schematic, where the line/rectangle with the ports is set up for extraction with extraction ports (?).  If so, then all you need to do is connect the line appropriately in the schematic and layout, and then perform the extraction.

  • Multiple port opened for one db connection.

    My java standalone server connects to sql server via MS sql JDBC driver(v 2.2). I saw so many port in Time_wait state to the db server in netstat. I did some search on the internet, found that this the nature of TCP/IP protocol. and we can live with it without modifying Windows config.
    however, I noticed on my side, there are two ports involved for each database connection. I think this is one of the reasons I have so many ports in Time_wait state.
    To me, it seems like the request to db server is done on one port, the response from db server is done on another port. is this implemented on JDBC driver layer or on sql server?
    please help !!!

    I saw so many port in Time_wait state to the db server in netstat. This suggests that you are not using any type of connection pooling, but instead are opening and closing connections pretty quickly, although it depends on what you mean by "many"; 10 or 100 might be a good number for a busy system, depending on your application. On some operating systems under high load, it could potentially be a problem if you are getting into many hundreds or thousands, but other issues usually drive people to using connection pools long before this issue would.
    however, I noticed on my side, there are two ports involved for each database
    connection. I think this is one of the reasons I have so many ports in Time_wait state.Not really. That might double the number, but the real reason is a lot of connection closes (real connection closes, not closes on a pooled connection).
    To me, it seems like the request to db server is done on one port,
    the response from db server is done on another port.
    is this implemented on JDBC driver layer or on sql server?That is totally up to the driver vendor; there's nothing you can do about it.
    please help !!!I'm not sure what you're problem really is - you might be worrying about something that isn't a problem. Is something bad happening that you're trying to fix, or did you just notice these expiring ports and start worrying about them?

  • Naming convention for Swing components?

    What are the official naming conventions for Swing components such as JButton, JFileChooser and so on?
    I know that "btn" is used for JButton variables. But where is a official list for all the prefixes?

    Well, if you unpack src.jar and consult the component classes you'll find how they set up their names.
    You can also call setName yourself to set a different name.

  • E-Series storage connectivity questions.

    Hey all, Long time NetApp FAS engineer here and this is the first time diving into the E-Series devices. Have some questions about the storage connectivity of these systems, mainly the 2700 series. As I understand it there are 3 options for storage connectivity, 2 or 4 ports 16 Gb FC\10Gb iSCSI optical, 2 port 10Gb iSCSI RJ45, 2 or 4 port 12Gb SAS DAS. So my questions are: 1. With the 2 port 10Gb iSCSI RJ45 -> Will thie negotiate down to 1Gb iSCSI connectivity?2. With 2 or 4 ports 16 Gb FC\10Gb iSCSI optical -> A customer received the "Cable,Direct Attach CU SFP+ 10G,2M". Do they have optical GBICs with fiber connections? Will this negotiate down to 1Gb speed or is that just for the RJ45 connections?3. Can the onboard 1Gb ports be used for storage connectivity? Thanks all.

  • TREX for multiple components

    Hello,
    we plan to deploy several NetWeaver Components (BW, EP, HR-e-recruitment, MDM), which all need TREX. The requirements for each system are relatively small, so we think about installing one TREX-system for all components. Is this feasible, does anybody have experience with this scenario? What if on of the connected components is upgraded or another component has to be added later on?
    thanks in advance for your input
    Richard

    Richard,
    We have deployed DEV and QA systems for e-recruitment V3.0 that share the same TREX 6.1 resource for candidate search functionality.  The only limitation that we experienced was that in the original planning, we were going to combine DEV / QA e-recruitment on a single server.  It was not able to be done based on a hard coded port used for communication between e-recruitment and TREX.

  • How do you set up Port Forwarding for ARD 2.2 in AEB N?

    Help,
    I'm a novice at Apple Remote Desktop (ARD) - not an IT guy, so it has to be pretty basic and detailed.
    How do you set up Port Forwarding for ARD 2.2 on the Apple Airport Extreme BS router, 802.11 N. I have one at each end of the internet connection. At one end I have an Airport Extreme N router with 2 macs and eventually 1 windows XP machine (if I can) that I would like to be able to connect to over the interenet (the clients) and at the other end, I have a Mac with ARD 2.2 installed also with an Airport Extreme N router. Note: Both routers use Static IP addresses and all computers use static IP's internally not through DHCP. What are the settings or directions to do this.
    I have read and printed out the directions for Configuration of ARD 3.0 that are posted many times in the ARD discusion group, but it uses a Linksys router ( http://www.starkpr.com/ard.htm posted by Dave Sawyer). The Mac router is different, particularly with the place to set a Private IP address. I'm not sure about alot of things, but especially about the Private IP address, what number do I set it to, the one that is in my Network connections list? It automatically changes to a different number in AE N setup for Port Forwarding (by one) as if it is not suppose to the same?????
    Are there any directions available that are as straight forward for the Airport Extreme N router, as the one's that are listed here for the Linksys Router's? ( http://www.starkpr.com/ard.htm )
    Any and All help will be greatly appreciated.
    P.S. I know I should have 3.0 but bought 2.2 just weeks before 3.0 came out and they would not give me an upgrade price, so I'm waiting for 4.0 to upgrade.
    Thanks,
    Jim

    I'm looking for some help connecting linksys IP Cameras to my home network to monitor my property when I'm travelling.  I used to do this with linksys WAPS, but since I've discarded all my old linksys networking and standardized on airport, I can't get these things working.  I know that I have to identify my camera through the DHCP table and set up port forwarding and there is the problem. 
    My network consists of 4  base stations set up in a roaming network - same network name and passwords.  I need to do it this way so I don't have to switch network when I move from one side of the house to the other, go to the cabana, or my shop in the barn.  The network works pretty well since I went to a roaming set up.  Good performance, yata, yata, yata.
    However, the roaming network requires the AEBS's to be set up in bridge mode, rather than sharing an ip address.  When the AEBS is set to  bridge mode, you don't see a DCHP table or have the ability to identify your IP Cam through the AEBS - and hence, no port forwarding. 
    I am able to identify and set up my Linksys IP Cam by locating the ip address on my FIOS router, even though, it's plugged into an AEBS.  I set it up, see the video, remove the ethernet cable from the IP Cam, restart - and I can't get to it from an AEBS.  In researching this, it appears, I should be setting up the AEBS to "share an IP Address", going to the DHCP table and identifying the camera's IP address and setting up port forwarding.  However, you don't see any of the DHCP or port forwarding options in Airport Network Utility when configuring in bridge mode. 
    I'm hoping I'm missing something here and that the solution isn't to set it up at the FIOS router level, but I'm beginning to think that's my only hope.  What concerns me there is that I should be able to see the IP cam on the network without port forwarding since I'm not coming from outside, and I can't even do this unless it's connected hard wire.
    I'd appreciate any insight into this that anyone might have.  I've hit the wall with what I know.
    Thanks.

    In a roaming network, your "main" router is the device that would require port mapping/forwarding to be configured in order to access the IP camera from the Internet. This router is also the one that would be provide the private IP address for the camera which you will want to be a static one.
    So as you described your network, the IP cameras should be getting an IP address or you assigned it a static one and this is the address that you would enter in the Private IP address (or equivalent depending on the router used) field when setting up port mapping.
    If you are not able to access this camera from the local network, then this should be troubleshot first.

  • I have a time capsule connected directly to fiber connection. I have connected a windows server directly to TC and configured it for remote desktop connection. From my interanet I can access srvr but not from my home. What config I need on TC?

    I have a time capsule directly connected to fibre optic point out. All pcs and macs are connected wirelessly to the internet. I have connected a windows server pc to TC. When configured for Remote desktop connection, I can access windows server from within interanet but don't know how to access it from internet. I guess I need to change some settings in TC to get some ip adress for the remote desktop connection from my home. Anyone who can help me out? Appreciate it.
    Narmin

    I am a little lost now.. I have read again your title and your first post.. and they seem inconsistent.
    In the title you state.
    From my interanet I can access srvr but not from my home.
    Interanet is not a word I know.. I assumed intranet...are you talking about internet or intranet? And just to be clear say WAN or LAN.. !! Is your home part of the interanet??
    In the first post you state,
    I can access windows server from within interanet but don't know how to access it from internet.
    Now this is more normal.. the issue is not in the home at all, it is accessible from there but fails from internet. If this is correct, then you can do a few obvious things to determine where the problem is.
    But first I need to know are you actually testing from a different internet connection to your home lan.. you are not just trying the public IP from inside the LAN as that will fail due to the TC not doing NAT Loopback.
    I am also assuming the TC is the only router in the network, and has the public IP on the WAN interface.
    And I am also assuming you have turned on the ping responder and you can actually ping your public ip from the internet and get a response. This helps no end in figuring out where there are issues. Strange but I have no idea if there is a ping responder in the TC WAN so you might need to forward that as well. Also if you have a dynamic public ip address are you using dyndns or no-ip or some other service to connect.
    1. Test bypassing the TC.. plug the internet connection straight into the windows server,, and test if you have access. If yes, the TC is the problem.. if not, your setup on the windows server is wrong.. look at firewall in particular.
    2. Assuming from test 1 the TC is the problem, Post the screen shots of the port forwarding setup for us to look at.. that is by far the easiest way to check it out.
    There are lots of references to port forwarding in the TC.. eg
    http://must-know-mac.blogspot.com/2008/07/how-to-port-forward-time-capsule.html
    The things that generally go wrong are firewall on the computer that is accepting the port.
    The ISP doesn't allow connections on a particular port. (not likely in your case)
    The router is behind another router.. double NAT will kill any port forward.
    Upnp has already allocated a port.. not an issue as TC doesn't use upnp although a reboot of everything after you set port forwards is well worth it.. amazing how things don't stick properly without a reboot.
    IP on the receiving device is not static and so changes.
    Not enough or right type of ports are opened. This is always messier than it looks as one port is often not enough for two way communications.
