Dedicated and SharedListener ?

hi,
Recently client has aske dme to make changes and make shared listerner back to dedicated listerner. I was just wondering is there anything called as dedicated and Shared Listener. I know we have a concept of dedicated and shared(MTS) server.
Can any1 give me an idea about dedicated and Shared Listener , if such thing exists ?
Thanks

Never heard of such thing for listeners. May be the client meant to make changes and rather than having one listener per db to one listener for all the databases(shared)?

  • Exclusive IP zone with one dedicated and one shared NIC

    Hi, I have a T series SPARC server belonging to two subnet (2 ethernet connection to 2 different VLAN), one used for mgmt purpose and the other used for application traffic. The server will have a zone which will exclusively use the link for application, therefore making it an exclusive IP zone. but the other mgmt NIC needs to be used for both global and local zone. this mgmt NIC is configured and up in global. But when I create the exclusive IP zone and add the dedicated nic (igb1) and then try add net -> set physical=igb0 -> set address=xxxxx -> end, I get error that I can't use a address in a exclusive IP zone. So my question is, is it possible to share a NIC on a exclusive IP zone? Thanks.

    igb2 is not plumb in global zone, exclusively added to this zone. igb3 is plumb and up in global, trying to share it with this zone. is this possible? if not, can I create a vlan tagged NIC out of igb3 and add it to the zone as exclusive? Thanks.

  • Dedicated and integrated graphics failures?

    Ok, I have a new MBPRetina, and I am having some problems that I am not able to find any replication of on the interwebs:
    1. Battery life "estimator": I am told by apple, 7-8 hours of battery life through simple browsing, no hardcore gaming or videos, right? I'm sitting at 51% and have an estimate of 3:47-2:40 (it keeps changing, why?) which doesn't add up (literally.)
    2. This is probably the cause of number 1, but I can only run the mac in dedicated graphics mode. I have to turn the automatic switching off, because watching any type of movie (colbertnation.com, rocketjump.com, youtube.com) results in frame skipping or glitching.
    3. Trying to use mission control is halted and jumpy. On the previous OS (which was on this computer), it was smooth and fluid. Went from full-screen app to MC with ease. Now, switching between full-screen apps or going to MC is stop-and-go and bumpy.
    My question is this: legitimate issues that need troubleshooting, or is it just the bumps that come with a new OS (this is the first time I've used the first public version of a mac OS, so I ahve no idea what kind of hiccups come with the first version.)

    Hello belenguer,
    If you want to play PC games (primarily 3D graphics), switch it to GTX.
    If you just do some normal paper works, just switch it back to Intel.
    However, if you are just using your GT72 as a small desktop on the table with AC adapter always plugged, there's no much difference and feeling to switch it back to Intel. Switching back to Intel is primarily for power-saving when using by the battery.

  • Wow ... I'm stumped ... I have been a dedicated and satisfied Firefox user .. OK ... I downloaded Firefox 8.01 to my Mac and now I cannot save any bookmarks even aftertrying everything I can find in Firefox Help

    Help with bookmarks ... I cannot save any bookmarks at all ...even in safe mode, I have reset Firefox preferences, restarted after installing, and looked at all of the Troubleshooting instructions.
    Really at a loss and will not be able to use Firefox until I figure ths out ... I love my Firefox and want it to work

    Thanks for the reply ... I was not able to locate the places.sqlite file as described. I did solve the problem by deleting Firefox .. emptying the trash and then I restarted the computer and re-installed a new download of the application. When I completed the clean install everything worked great. I like the new look and features of 8.0.1 and look forward to using it from now on ... Thanks again for trying to help core-el ,,,

  • Shared and Dedicated Mode in Oracle 8i

    Can any one describe what is basic difference when we install Oracle8i in dedicated and Shared modes. I have to create Oracle8i Database for not more 150 users. Actually less then 20 users might be accessing database but in future it can go up to maximum 100.

    WIthout understanding your application and hardware in some detail, it is impossible to say which mode is better-- and that's without accounting for a mixed-mode setup where some connections are shared and some are dedicated.
    If there are going to be 20 simultaneous connections, dedicated server is almost always preferred. If you start to get up to 100 simultaneous connections, depending on your hardware, it may become appropriate to use shared server. If you have a high-end multi-CPU machine, it will easily handle 100 connections. If you have a low-end single-processor Windows server, you might have problems with dedicated server.
    OLTP systems tend to be more amenable to shared server than DSS systems, because sessions spend a lot of time idle in the former type of application.

  • Problem with application and storage and memory.

    I NEED HELP!! I am trying to add more application s to my Blackberry Curve 8330. My problem is I don't have enough storage to even add a couple of application s and their updates to my phone. I have an 8GB media card with like 7.3GB of free space. Also, I only have 3.7MB of free space on my device. One of my questions is, How do you add things to your memory card instead of your device memory? Second thing is, if anyone decides to respond to this discussion, please use simple steps. Thanks soooo much.
    ~Robin

    Hello!
    There are three types of potential memory on a BB: 1) Application Memory, 2) Device Memory, and 3) Media/SD Card Memory
    Application Memory -- This is the most crucial; it is the protected (not user accessible), dedicated, and fixed (in size) space that is available as the destination for the installation of applications (plus some application storage, overhead and such). You cannot touch AppMemory. You cannot improve the maximum AppMemory that your BB has. It is what it is. Applications can only install here...there is no option.
    Device Memory -- This is space on your BB that you can touch to store files, pictures, media, etc. Typically, it is not terribly large, but it is available to you.
    SD/Media Card Memory -- This is what it says...your SD card, for you to store files, media, pictures, etc. It cannot be used as the target for installing applications (only App Memory can be used for that). It can be as large as your BB OS can support...see this KB:
    http://www.blackberry.com/btsc/KB05461
    On some devices/OS levels, you can only see "File Free" (Options > Status), which I think is equivalent to AppMemory. On other devices, you can see all three memory usage levels (Options > Memory). Here are some guidelines to use:
    http://www.blackberry.com/btsc/KB15345
    http://www.blackberry.com/btsc/KB14320
    http://www.blackberry.com/btsc/KB14213
    Lastly, it is always important to properly close applications when you are done with them. Using the Back or the Red key will not do this -- those leave it to the app to decide what to do...and some will leave themselves resident in memory, consuming resources on your BB, slowing the overall performance. Rather, to close an app, press and select "Close" or "Exit"...that will force the application to be closed, freeing up for your new use the resources it was consuming. Some apps will always remain running (typically -- BBMessenger, Browser, Homescreen, Phone, and Messages)...but, you should still close them properly - especially the Browser...if it is left on an active web page, it will not only consume extra resources but battery power as well.
    Further, anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure. Some have taken to doing this on a regular basis as a preventive measure...some as frequently as once per day. Others have obtained the QuickPull app to automate a simulated Batt-Pull.
    Best!
    Good luck!

  • ALERT: Google account sync broken on webOS devices (and a fix)

    MUST READING FOR webOS USERS WHO SYNC CONTACTS WITH GOOGLE ACCOUNTS:
    Earlier this week I began having trouble with my Pre3.  It spontaneously restarted and pretty much wiped everything.  After logging back in to my webOS account, I then began having trouble logging in to my several Google accounts.  Each time, I got either an "unknown error" message or a message that my credentials were incorrect.
    A very clever webOS developer (consider throwing him some bones if you use his patch...see below) figured out that Google changes to https (whatever that means) were the culprit.  I don't understand enough of the jargon to explain it, but the issue seems to effect Google accounts (primarily contacts) which are newly added to a device or re-added after a reset or doctoring your device, more so than accounts that are already on your device.
    However, even if your existing gmail and calendar accounts still sync, you are strongly advised to check...Google contact sync is probably broken and you might not realize it.  In this condition, contacts which are newly added directly on device will not sync to google servers for backup and syncing with other devices you might have, unless you install the patch below.
    I can vouch for that.  I had added several new contacts directly on the phone during the past week, but after this week's fun & games, I found that none of the newly added contacts had ever synced to my online Google contacts, which means they didn't sync back down from google's servers onto my other devices.
    SO...GO HERE NOW:  The patch which is discussed in this linked article on webOS Nation has definitely fixed the sync problem on my Pre3.  It requires the use of webOS Quick Install.    While you're at it, install Preware using webOS Quick Install, and expand the usability and speed of your webOS device. Then install a Preware app called Internlz Pro which is installed with Preware.  Then you email the patch to yourself, click on the attachment, and Internalz Pro installs directly without having to connect to your computer.  
    Please post back in this thread if this issue has effected your phone or tablet, and if you have any problems installing the patch.  I haven't used webOS Quick Install in a long time so I had to figure it out from scratch.  I install from a MacBook and it works just fine.  There is also an on-device option called Internlz Pro which is installed with Preware directly on the phone...you email the ptch to yourself and Internalz Pro will install it.  
    HP/Palm had given its support to the webOS Homebrew Community, so let's use this information here to keep these devices healthy.  You will find much more detailed informatio in the forum linked above where the patch is located, and how to get webOS Quick Install and PreWare downloads.
    I'll also use this experience as a plug for PreWare and the really selfless developers who support our favorite OS and catch stuff like this when it happens, and turn around a patch in a day or two so that the community can benefit..  There are tons of improvements just waiting there for your webOS devices.  Tweaks.  Patches.  Enhancements of all sorts to make your webOS device run faster and jump higher.  All free, robust, and ready to keep webOS cool and relevant for many more years, for a lot of users.
    No particular skills or knowledge are needed to take advantage of PreWare.  The directions are very simple.  You already have the hardware.  This experience shows me that the webOS homebrew community still has some dedicated and pretty darned skilled developers at work for the sheer joy and pride (and a few $$ should someone toss them a few) of keeping their...our...beloved webOS alive.

  • Shared versus dedicated connections in the fragmentation of shared pool mem

    Hi,
    I have a old Oracle 8.1.7 database server.
    I have a legacy application with no source code. This application don't use memory efficiently (no bind variables, etc.) , ie memory becomes fragmented.
    I know that exists two ways to connect the database (dedicated and shared)
    Based on this, I want to know which of the two options creates more fragmentation. I know that recommendation is to use dedicated connection, but I'm not sure if this is recomendation is applicable in this particular environment.
    Thanks in advance.

    Whether you use shared or dedicated connections makes no difference for fragmentation in the shared pool. Whether your hard parse or do not hard parse does matter.
    Measures you can take
    - make sure often used packages like dbms_standard are pinned in the shared pool using a startup trigger
    - set session_cached_cursors to 50 or 100. This will reduce parsing.

  • SAP Database is in dedicated or shared

    Hi Gurus
    I have a doubt. Our SAP Database is working on dedicated or shared mode. when i was passing thro some oracle documents i have read as per tnsnames.ora file we could come to know whether the dedicated or shared mode. I have checked our SAP systems in one of the SAP system which has seperate database server and two other separate application servers which does not show the connect_data as dedicated but as (SID=%sid%) but in another SAP suystem where it is stanalone system which shows dedicated mode in connect_data parameter in tnsnames.ora file.
    i want to know the basic mode our SAP works in dedicated mode or shared mode. if it is dedicated mode in what all circumstances it will be decided or if it shared mode then what are all the conditions are set for shared
    Pls help
    regards
    bala

    Hello Bala,
    > i want to know the basic mode our SAP works in dedicated mode or shared mode.
    Just query the view V$SESSION (http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2088.htm#i1414383)
    > SQL> SELECT SID, SERVER FROM V$SESSION;
    Here is a really nice explanation about dedicated and shared connections:
    /message/2114775#2114775 [original link is broken]
    Please read this, because i think you don't understand the concept about dedicated/shared .. it is just a "connect option" not really a mode in that the oracle server is running.

  • Permissions and FTP set up

    I am trying to set up a new Mac Mini with Snow Leopard Server. To be honest, given I have managed several other Linux boxes, both dedicated and VPS, I am a bit surprised how badly my first adventure with 10.6.1 is going
    I have a whole range of issues but right now my biggest challenge is that I can't seem to edit any config files (httpd.conf, php.ini etc) using an editor (Coda) that is locally installed. I am logged into the Mac as admin, there is only 1 account - the same admin account that allows me to do everything else but when I try to save a file that I have edited, I get a permissions error. If I look at the file properties (Option-i), I can see I own the files are they are CHMODed to 644. I have tried restarting services - Apache, MySQL etc but to no avail. I just don't get how, when I am the only user and an admin, why I can't edit these files - I must be missing something fundamental...
    I am seriously considering trashing the Snow Leopard Server install and replacing it with XAMPP but then I lose the whole point of buying an integrated server.
    Can anyone suggest what might be going on with permissions and why, as admin, I can't edit my own files?
    As a sidenote, I am also having trouble with SLS's handling of vhosts. I am used to setting these up manually and it works just fine but somehow using the Apple interface, it's just not happening. I set up the folders and vhost name but can never seem to browse to the folder using another mac on the network - only the default SLS page. I don't expect anyone to explain this in detail here but if you could point me to a decent resource or some proper documentation for 10.6 rather than previous versions, I would appreciate it!
    Thanks

    Mac OS X Server is divided into two parts; the Apple UI layer and tools, and the Apple directories, and the underlying Unix layer. Once you're active in the lower layers, you're expected to be familiar with Unix server configurations and management. And you're expected to manage the configuration files and other such either in conjunction with the GUI tools and in a compatible fashion, or (depending on the changes you're making) taking over from the GUI tools and managing the environment entirely manually.
    The configuration files are typically managed via the GUI and Server Admin and related tools for a baseline configuration.
    If you're editing files, you can end up derailing the GUI management tools; proceed here with caution. You can end up reinstalling.
    To edit the low-level configuration files, the usual is with something akin to this:
    +sudo nano /etc/apache2/httpd.conf+
    or related. sudo means you'll have to enter an administrative password. vim and emacs are also available. httpd.conf is one of the many files that is typically managed with Server Admin.
    I don't know off-hand if Coda can edit and can save edited text as plain-text files; the configuration files have to be plain-text, and not RTF or otherwise. (nano, vim and emacs can.)
    As mentioned; you may need to reinstall here, if you're off editing configuration files manually. Making the choice to edit files manually is fine, but that can mean you won't be using Server Admin.
    Your first requirement here with getting Mac OS X Server going is to get DNS configured and working. This is one of the first steps, and failure to have functional DNS means the rest of the stack can be unstable or uncooperative.
    Some items for your reading list: [DNS Notes|http://labs.hoffmanlabs.com/node/1436] and [Apache virtual hosting notes|http://labs.hoffmanlabs.com/node/1329], and definitely the [Apple Mac OS X Server manuals|http://www.apple.com/server/macosx/resources/documentation.html]. You're active at the Unix layer, which means you'll want to be familiar with the Command Line manual, as a start.
    I have an article on [configuring and activating ftp|http://core/node/942]; that's easily possible. In general, sftp is easier to deal with, and more secure.

  • Query on dedicated server?

    Is it possible to connect to the database through various dedicated connections?
    Is there any parameter to limit the max number of dedicated connections?
    or
    only one dedicated connection is possible for each database?
    Regards,
    Rajesh

    OK, let me try to explain the difference between dedicated and shared server connections this way.
    Oracle uses what is known as a two-task architecture. You have a front-end program that connects to Oracle and a session is created to support this front-end user connection.
    Now to perform the work for this session Oracle creates a seperate back-end process.
    When dedicated sessions are used every session has its own dedicated back-end process to perform SQL. When shared server sessions are used every session does not have a dedicated back-ground session but rather the requests (SQL) are passed to a pooled back-end process.
    Now, no matter if dedicated or shared server connections are used a single user may open multiple connections to Oracle (providing the user has not been limited via a user profile). A connect is basically a path between the user client and the Oracle database. A message is sent to the listener that say hey I am user U1 on OS PID X1 at server S1 and I want a connection. The listener assigns a port and creates a session for this connection. If the same user askes for another connection the request will will say hey I am user U1 on OS PID X2 at server S1. Because the source is a different local OS process Oracle will create a new session for it.
    It is actually possible for a single OS process to open multiple connections to the same Oracle database by providing a unique copy of the necessary control structures for Oracle but in most cases if you invoke a program such as sqlplus multiple times then you will get one connection, one session, and in the case of dedicated session one background Oracle process per OS process running sqlplus.
    You can find more information on this topic in Ch 9 Process Architecture in the Concepts manual (10gR2).

  • Forcing shared/dedicated server

    Hey, I have two questions about dedicated and shared server.
    1. If the applications use directory naming and shared server, but for one host we want to use dedicated in we can create another service for the same instance but using dedicated server, right?
    Is it possible to set, in sqlnet.ora for that one "dedicated" application
    NAMES.DIRECTORY_PATH=(TNSNAMES,LDAP)
    then create tnsnames.ora with THE SAME service name as in ldap, but using dedicated server? Since there's TNSNAMES before LDAP in sqlnet.ora will the tnsnames service name be used first? Or will we get error?
    2. If I have sqlplus on remote machine with tnsnames.ora indicating the connections to orcl use shared server, but I connect to sys as sysdba (or just an administrator) will the use of dedicated server be forced?
    Thx.
    A.

    1) That should work. If the SQL*Net layer is told to look in the tnsnames.ora file first and the alias is found in the tnsnames file, it shouldn't look in OID. On the other hand, you'd eliminate a lot of the utility of having OID set up since you'd have to modify a bunch of tnsnames files when other connection information changed.
    I would tend to think that you want the applications rather than the hosts themselves to determine whether to use a shared server connection or a dedicated server connection and that you want to have TNS aliases for SomeDatabase_Shared and SomeDatabase_Dedicated in OID.
    2) Yes, SYSDBA connections are forced to use dedicated server connections.

  • "Dispatchers" parameter in dedicated mode

    Hello,
    I've noticed that the "dispatchers"' parameter in dedicated mode looks like this (on 10.2.0.1.0 db) :
    dispatchers=(PROTOCOL=TCP) (SERVICE=sidXDB)
    What is the SERVICE parameter for, and why is it set to this default value in dedicated mode ?
    Is the SERVICE parameter always set for dedicated servers only ?
    Otherwise, how can I recognize dedicated and shared mode when I look at the insatnce parameters ?
    thank you
    Regards,
    Antoine

    Actually you can configure a instance to use dedicated server mode and shared server >mode at the same time: it's up to the client to connect using the right configured service >that will make the right mapping.You are right Pierre.
    But I've tried to configure several instances with DBCA wizard, both in dedicated and shared mode :
    - when dedicated mode is selected, dispatchers parameter is set like this : "dispatchers=(PROTOCOL=TCP) (SERVICE=sidXDB)", and all connections at the instance will be in by default dedicated mode, even if the "shared_servers" parameters is greater than 0
    - when shared mode is selected, dispatchers parameter is set like this : "dispatchers=(PROTOCOL=TCP)"
    I thought that the instance would run automatically in shared mode if the "shared_servers" parameters is greater than 0, but that's untrue
    Besides, I don't understand the link between the "(SERVICE=sidXDB)" option, which seems to be related to the XML database, and the connection mode to the instance.
    This is quiet confusing to me, there is obviously something I don't know or I don't understand

  • Dedicated or Shared Sessions?

    I have a 10g SE1 + ASM running in Windows 2003 ES with 4GB RAM with /3GB switch and 7TB JBOD storage. Our custom data mining applications access this database from a grid of 15 servers. Application architecture uses a mixture of hibernate, roll-your-own connection pooling in Java, and daemons with dedicated sessions. In all, we typically have 200 sessions but only 3 to 9 are active at any given moment. Individual queries and transactions range from sub-second to 3 hours in duration.
    I’ve run the system with MTS and in dedicated server mode; it runs either way. I have never tried tweaking multiple shared_servers, dispatchers or circuits.
    Right now it seems to run fine with 200 dedicated sessions, but it does gobble up a lot of unused PGA memory for the inactive sessions.
    In our situation, what is the best configuration, MTS, or shared, or dedicated, and why?

    Mark, I think that physically a shared server process is no different than a dedicated server process in Oracle on Windows - both are threads in the oracle.exe process image.
    The only real difference is that one deals directly with the client, and the other with a virtual circuit.
    This then raises the question about the PGA and UGA. As the thread runs in the oracle.exe space, it has direct access to, and uses, the data segment (DS) of oracle. The PGA is likely a dynamic memory allocation - so too the UGA for a dedicated thread, while a shared thread will use the SGA instead (for the UGA).
    Now assuming that my speculation is not far of, there are very little overheads between dedicated and shared server threads on Oracle in Windows - except for the dedicated servers being more and thus more PGAs given the nature of these threads versus shared server threads.
    This is unlike Unix where there is a large physical difference as each process (dedicated or shared) has data segment and code segment. The resource footprint for a process is a lot bigger.
    A concern of mine... Windows is excellent at running threads.. it really strains running lots of physical processes (unlike Unix/Linux). But as threads share the same code and data segments, a single thread running into a severe bug can potentially corrupt the entire physical process image, crashing all other threads in it. At least, this has been my experience doing Windows server development.
    Would be nice to read a technical paper on just how Oracle implements their shared and dedicated server models on the Win32 API.
