MeetingPlace Express strange problem !

Environment:
MeetingPlace Express 1.1.1.11
CallManager 4.1(3)sr2
Voice Gateway 1: 2821 (c2800nm-advipservicesk9-mz.124-4.T.bin) + VIC2-4FXO
Voice Gateway 2: 2621XM (c2600-advipservicesk9-mz.123-14.T5.bin) + NM-2V + 2* VIC-2FXO
VG1 connect to CallManager using H.323, VG2 connect to CallManager using MGCP
MeetingPlace Express connect to CallManager using H.323.
Problem:
When dial-in from PSTN to VG1 and VG2, both are well; but when using "Find-Me" feature, MeetingPlace express dial to user, users via VG2 are can sent dtmf with MeetingPlace Express, but users via VG1 can not sent any dtmf digit to MeetingPlace Express. So users via VG1 can not enter the meeting.

  • Disk space problem on MeetingPlace Express

    I get the email below daily. I'm thinking it's ok to cat /dev/null the cma.log file?
    I also think I might be able to do the same thing to stdout.old?
    Anything else I should try other than the instructions?

    This is an automated message from the MeetingPlace Express system with
    hostname [meeting.afgrp.com] to inform you that disk space is low.
    Details on where the problem is and how to resolve it are indicated below.
    Low space in partition /. Percent used = [90].
    The following files might cause trouble. However, inspect each one to make sure.
    Look specifically for large files with old timestamps. Also, note that some of
    the files indicated might have been previously mentioned. In this case, use the
    prior instructions to handle these files rather than the instructions below.
    If you are uncertain, contact Cisco TAC for confirmation/advice.
    For the files below, use the following procedure to empty these files rather than
       delete them outright.
             1. For each file to be emptied do:
                 cat /dev/null > <filename>
             2. After all files that you wish to empty have been emptied, do:
                 su   // Enter 'root' password.
                 mpx_sys restart
    -rw-rw-r--   1 mpxadmin mpx     283120801 Apr 11 02:00 /var/mp/ConfSchd/stdout
    -rw-r-----   1 root     root     127007041 Dec 22 05:30 /var/spool/compaq/cma.log
    In general, to free up disk space where it is uncertain exactly what files are in question,
       do the following:
    1. In general, go to places like /root, /mpxadmin, /tmp and do "ls -la" to look
         for large files. If a file is large, old, and seems like some kind of log or
         error file, it could be a candidate for deletion.
    2. Generally files of type log (*.log), stderr, stdout, or txt (*.txt) are the
         best candidates to look for. A good command to look for these types of
         files with size of 10,000,000 bytes or larger is:
           find / -name "<file type>" -exec ls -la {} ; | awk '{if( >=10000000) {print} }'
         For example, to look for all log files 10,000,000 bytes or larger on
           the entire system:
             find / -name "*.log" -exec ls -la {} ; | awk '{if($5 >= 10000000) {print} }'
    3. If you have a specific problem partition that you are trying to reduce size
         for, do the following:
         1. Find out the directory name of the top of the partition from "df".
         2. "cd" to that location.
         3. Then do: du -x -b --max-depth=1
         4. Look for the directories that are really large.
         5. Then "cd" into the worst subdirectory (or subdirectories).
         6. Get a list of all large files from current directory location and lower:
               (This example assumes 10,000,000 bytes and a check for .log files.
                   Note the starting location of '.' (current location) rather
                   than '/' (entire disk) ).
               find . -name "*.log" -exec ls -la {} ; | awk '{if($5 >= 10000000) {print} }'
    Complete output of the 'df' command:
    Filesystem           1K-blocks     Used Available Use% Mounted on

    Hi Josh,
    It seems that the root partition of the MeetingPlace Express server is almost full. I have attached a document for your reference which can be used to minimize the disk space issues.
    Once the steps mentioned in the attached document are completed, run the command "df" to check the disk space.
    If you do not see much improvement in the root partition, then in that case some other files might need to be removed from the server to increase the root partition space.
    If any of the partitions reach upto 90% or above, then the server might behave unexpectedly.
    Feel free to revert if you have face any issues or have any queries.
    Regards,
    Rishabh

  • Strange Problem with Toshiba Express Media Player on Satellite M115-S3094

    I'm experiencing a strange problem in my Toshiba M115-S3094, which was pre-installed with Windows XP Media Center edition and which also had the Toshiba Express Media Player.
    I had previously done a clean Vista installation on it, and then I decided to revert back to XP with my recovery DVD. I did the same procedures of first installing Express Media Player from Backup (which I made when i purchased the laptop) and then installing XP from Windows XP recovery DVD from Toshiba.
    The steps included:
    1- Deleted partitions from Express media player recovery disk
    2- Installed express media player
    3- Recovered Xp from Recovery DVD, by selecting "Recover without changing Partitions" (there is no expert mode)
    Everything went very well (i.e. the installation)......But now after shutting down my laptop as I press the Express Media Center button, the "Express Media Player" logo appears on the screen after loading for 5 seconds laptop shutdowns,
    I tried to open it again and again but the logo appears for 5 seconds and then my laptop shutdown....
    Laptop works fine when I logon to windows by pressing power button.
    Can anyone help on this strange issue..?

    Hi Jaba
    Thnx for reply.
    Now i would answer the questions asked by you and try to clear you confusion,
    Yes, Express Media Player was previously installed on my machine, and I have used it, it was perfectly working.
    About installation of Media Player, The whole story is that, firstly i wasnt known about how to make a Toshiba express media player recovery cd through windows, so downloaded an ISO of the media player from a forum and install media player by first deleting partitions.
    After that I can again installed xp through recovery dvd and choose the option "out of box" state and then selected "install without changing partitions"
    After a successfull recovery, I shutdown my pc and pressed the media player button, the media player logo appeared for 5 seconds and then my laptop shutsdown, this is happening all the time when i start my laptop by the Express media player button.
    After this I read somewhere how to create a backup recovery cd for Express media player, So i run the recovery disk creater and made a backup of Toshiba Express media player.
    After doing the above procedure I again formated my hard drive through recovery dvd and selecting the option "Delete partitions and overwrite sectors". When this was finished, i booted my laptop with the newly made recovery cd for express player, after selecting English as my language, This it what said:
    "Installation Error" An error occured due to wrong system ID or unsufficient space on hard drive, press escape to quit.
    THE ABOVE IS THE WHOLE PROCESS IN COMPLETE DETAIL.
    AND JAMA,
    About the link you provided, it says that on the Recovery dvd select the option for "Expert Mode", but in my recovery dvd (for Toshiba M115- S3094) there is no such option as expert mode, there are only two options
    1- Restore laptop to "out of box" state
    2- Format Hard Drive

  • MeetingPlace Express 1.1 NFR Installation Problems

    Hi.
    On the installation guide of meetingplace express shows the MCS 7825H-3.0-IPC1 as a supported server and the DVD should be capable of booting itself and install the Linux OS and then the Cisco Application.
    I'm trying to install the NFR in an MCS-7825H-800 instead of the MCS 7825H-3.0-IPC1 but the DVD will not boot automatically. The MCS-7825H-800 comes with a CD ROM but I changed it to a DVD ROM. Any ideas? I don't have an MCS 7825H-3.0-IPC1 at the moment and I would like to install the MeetingPlace Express NFR to test it out.
    Thanks in advanced,
    -Jose

    ErnestoG

    hi Ernesto,
    As the problem you are facing is a dial out issue on MPE,  go
    through the checklist mentioned below in order to confirm the configuration
    is intact.
    Here is the checklist :
    1.    Ensure that H323 GW is defined on CCM/CUCM.
    Device > Gateway > find.
    Look for a device name that equals either MPE's hostname, FQDN, or IP
    Address.
    2.    Ensure that h323 Gateways are configured on MPE.
    MPE Administration Center > System Configuration > Call Configuration > H323
    Configuration
    Ensure that h323 is enabled.
    Ensure that you have entered your CCM's IPs in h323 Gateway 1, 2
    3.    Ensure that CCM's interface with MPE is up.
    Ensure that MPE's IP Address is listed under the "IP Address" column.
    Ensure that this IP Address is that of the FIRST NIC on MPE, not the second.
    4.    Verify that MPE has the CSS required to call the destination.
    FIRST, FIND MPE's CSS:
    When MPE places a call, the CSS in question is Device > Gateway > MPE-GW >
    Inbound
    THEN the relevant config is under Device > "Call Routing Information -
    Inbound Calls" > Calling Search Space
    SECOND, FIND DESTINATION PATTERN's PARTITION:
    If the destination is an IP Phone within the CCM/CUCM Cluster, then the
    relevant config is under Device > Phone > click on Directory Number in CCM.
    If the destination is a PSTN endpoint/phone, then the relevant config is
    under Device > Route Pattern.
    5.    Ensure that your user profile is set to allow outdials.
    MPE Administration Center > User Configuration > User Profile Management >
    Your User Profile > Can call out of meetings should be set to "Yes".
    6.    When you place a call from  from the CLI, the system applies permissions
    from the "Guest" User profile since mpxadmin  or root are not Users within
    the MPX application. To allow this to work, you need to  verify two
    settings:
    MPE Administration Center > User Configuration > User Profile Management >
    Guest > Can call out of meetings should be set to "Yes".
    Ensure that the Guest profile is not in a "locked" state.
    MPE Administration Center > System Configuration > Usage Configuration >
    Allow Guest outdials should be set to "Yes".
    Hope this helps!
    Thanks,
    Karthik

  • A very strange problem in netbeans

    i debug a project in netbeans,a a very strange problem happens.
    a member variable was different between wtk20 and wtk22.and the variable was changed many places so it's hard to trace!
    but there hasn't the problem when i debug project in jbuilderx!

    My problem is, even I've written the SQL in the correct syntax, in my java code, it just look like this
    adc.SQL("insert into test(subject, content) values('" + sf.filter(subject.getText()) +"'"
                                  + "," + "'"
                                  + sf.filter(board.getText()) + "')" );
                                  subject.setText("");
                                  board.setText("");
    where subject is a textfield and board is a JTextArea and sf is a string filter which use regular expression, I basically want to insert the string in these component into the database, Many strings work, but client for updates can't be inserted.
    With my best,

  • MeetingPlace Express Assistance

    Hi All,
    We have MeetingPlace Express version 2.1.1.2.
    We need to configure it to accept any user to make a non-scheduled conference directly, without requesting the user to enter his profile ID and profile password, and without the need to add the data of the users into the MeetingPlace.
    We just need it to act as an audio conference bridge, so we need the user to dial the MeetingPlace number, then he can enter a certain password (one password for all our staff) to enable our employees to log into the MeetingPlace, and then get the Meeting ID and Meeting password and start the meeting.

    Sherif,
    You are going to want to export using all of the headers and leaving them intact in the import file.  You will want to follow the steps below for a successful import as the system is really sensitive that the data is formatted a certain way.
    Create a test user profile in MPE manually so that you can get the file format of the import file with the headers.
    Export User Profiles.
    Export this test user profile to a file and include the header information.
    This will create a User_Profiles.txt file that you will save and then open up in Excel. (Follow these steps below to ensure that the file is formatted correctly)
    1.  Within Excel, click on the Open tool on the toolbar. Excel displays the Open dialog box. (To display this dialog box in Excel 2007/2010, click the Office button and then click on Open.)
    2. Using the Files of Type drop-down list at the bottom of the dialog box, indicate that you want to open Text Files (*.prn; *.txt; *.csv).
    3. Select the saved export file.
    4. Click on Open. Excel starts the Text Import Wizard, displaying the Step 1 of 3 dialog box.
    5. Make sure the Delimited choice is selected, then click on Next. Excel displays the Step 2 of 3 dialog box.
    6. Select Comma as a delimiter, then click on Next. Excel displays the Step 3 of 3 dialog box.
    7. Click on Finish. Your file is imported.
    8. Once the file is opened up in Excel, import your users into this spreadsheet so that they conform to the necessary format and the required headers.Next, find the "isLocalUser" field and set the parameter value for al user profiles from "No' to 'Yes'.  Then find the EncryptedProfilePWD and EncryptedUserPWD fields.  Remove the 'Encrypted' portion of the field name in the header so that they now read ProfilePWD and UserPWD.  Make sure the value for the ProfilePWD for these user profiles is a standard alpha password. (cisco)  Then make sure the value for the UserPWD for these user profiles is a standard numeric password. (12345).  You may just be able to leave them as they are from your import.
    9. Save the file with the changes.
    10. Go to the Application MPE Web Page and then Maintenance-->Import Data-->Import User Profiles.
    11. Select 'Add Profiles To System', select file to import, and set Overwrite field to 'Yes".  (You should also set the log information to file option.)
    12. Hit 'Execute' to import the user profiles to the system.
    13. Once this is completed successfully, then go check the User Profile configuration to ensure that all users are imported correctly into MPE.
    If you run into any problems with this procedure, please open an SR with TAC so that we can assist further.
    Thank You,
    Gerry

  • MeetingPlace Express User ID Change

    I am running MeetingPlace Express 2.1.1.2 and it is AD/CCM Integrated. We in the process of changing our AD User login ID and I may have run into a problem. From Call Manager perspective I just perform a full sync and it is good when a change is made.
    However I cannot modify the user ID in Meeting Place Express.In reading the on line help, it says "Deleting a user profile also results in the removal of all meetings scheduled by that user from the end-user web interface; however, any meetings scheduled by that user still exist in the system"  Does that not contradict itself?
    When I add the user back with the same profile ID, will it re-associate the scheduled meetings? Also, is there a way to manually modify/sync the user id rather than deleting and re-adding?
    Thanks, in advance.
    Doug

    I still don't understand how and when you are encountering that obstacle, but nevertheless if you cannot surmount it you will have to solicit Apple's help.
    Apple can reset your iPhone if you present them its original, dated sales receipt. I believe you will have to do that in person at an Apple Store or an Apple Authorised Service Provider.

  • Strange problem with CachedXPathAPI

    Hi,
    I have a strange problem when using CachedXPathAPI.selectNodeList(node, nodeName);
    If the nodename is replace with a string literal e.g
    nodelist = cachedXPathAPI.selectNodeList(node,"//ROW");or with a variable name that uses a literal e.g
    String nodeName = "//ROW";
    nodelist = cachedXPathAPI.selectNodeList(node,nodeName);Then the nodelist is retured perfectly fine.
    However, if the nodeName comes from a hashMap e.g.
    String nodeName = (String)hashMap.get("NODENAME");
    nodelist = cachedXPathAPI.selectNodeList(node,nodeName);then I get the following exception:
    org.apache.xpath.XPathException: Can not convert #STRING to a NodeList!Has anyone got any ideas why this is happening or how I can get around it?
    Thanks
    Jag

    A String is a String. The program doesn't know it came from a hashmap. So the difference must be related to the contents of the String. Which you haven't showed us. Perhaps you don't even know what it is yourself... in which case you should find out. My bet is that it's an XPath expression that yields a result tree fragment, but I really don't know enough about that API for that to be more than a guess.

  • MeetingPlace Express 2.1 Record Meeting issue

    Hi,
    I have a problem when I try to record a meeting. The error message is:
    "MeetingPlace Express failed to start recording, internal error."
    Any idea what's wrong?

    You can enable or disable an automatic backup.
    If the automatic backup is enabled, an L0 backup happens twice a week, every Monday and Thursday
    at 11:00PM, local server time. The L1 backup is run each day at 1:00AM,local server time, while the L2 backups are done daily at 4:00AM,
    8:00AM, 12:00PM, 4:00PM, and 8:00PM, local server time. The schedule is stored in the crontab file.

  • Strange problem with Database LInk

    Hi Everyone,
    I have strange problem with Database Link in Oracle 11g Express Edition;
    There are two computers: computer-server and computer-client. Tnsnames.ora are the same on both computers ie.
    CT =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof)(PORT = 1521))
    (CONNECT_DATA = (SERVICE_NAME = XE)
    I created database link :
    Create database link zdalny
    Connect to <user_id> identified by <password>
    using ‘CT’;
    Client can’t connect with server when I am using above command. But when I change “using” for using ‘krzysztof:1521’ or using ‘krzysztof’ or using ‘server IP:1521’ – everything is ok.
    Why I am asking. Because in all materials which I am reading about Oracle command with using ‘CT’ should be working correct. But there is not. Do you know, why?
    Thanks in advance and apologize for my English.

    PS. I tried with using 'XE' - not working.Assuming that is the correct tnsnames, of course XE is not working. You don't have a tnsnames entry for 'XE'.
    You need to be aware that when using a dblink, the client is the db in which the link is defined, not the desktop from which you connect to that database.
    I think you need to start here:

    http://edstevensdba.wordpress.com/2011/02/16/sqlnet_client_cfg/ (Help! I can’t connect to my database (part duex) )
    The fact that your client (db link) is a database doesn't change anything taught in the above.

  • Strange problem with In-line If-Else block

    Hi!
    I've discovered a very strange problem with the following code:
    enum Enum {
            A, B, C
        public static void main(String[] args) {
            Enum e = Enum.C;
            Object o = e == Enum.A ? 1 : e == Enum.B ? 2 : null; // Throws NullPointerException because of the null. Why???
        }I'm using Java 6
    Thanks in advance!

    Instead of guessing what the problem is, how about we go to [the source|http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#15.25] and see what's actually happening.
    Our line is
    expr ? <int> : (expr ? <int> : <null>)Let's look at the inner conditional first. By JLS 5.1.8, we have two different types, neither of which is a reference type. The null is convertible to int, so we have two types convertible to numerics and we apply unboxing to the null, which is where your error is coming from.
    Your fix works because Object is not convertible to int, so we fall through to the last case and use boxing on the ints instead of unboxing on the null.
    Another way to fix this is to use Integers instead of ints. Since Integer is a reference type, we hit the third case and never try to unbox.
    Object o = (e == A ? Integer.valueOf(1) : (e == B ? Integer.valueOf(2) : null))

    I am facing a strange problem on new iphone 5 that I bought last week. The maps app and the places in photo gallery shows the pin and my location, however there is no information of locations. Tried to close the apps, phone restart, reset etc. I am accessing it via strong wireless connection and it works fine on other devices. Please help.

    Then no information exists.  Use the Report a Problem button within the app to report it.
