Download

Current version 3.1.1 (released September 21st, 2016):

Installation

Simply extract the zip file to a folder of your choice and start “Mumbai.exe”.

Update

You can safely extract the files from the zip archive to your existing Mumbai folder and overwrite the existing files (configuration files are kept).

When updating from version 2.x to 3.x the following breaking changes apply:

  • Any custom command that you set up on the toolbar will be gone.
  • If you use a master password to encrypt connection passwords, you will loose all your stored passwords with this release. To prevent this, run your current version first and remove the master password, before updating to this version.

Change history

 

Changes for 3.1.1:

  • Now using Remote Desktop Plus instead of “LaunchRDP.exe” which fixes connecting to Windows Server 2012+/Windows 10+
  • Creation of Mumbai42 schema (needed for alert log fetching) on 12c fixed
  • Fixed fetching of alert log on RAC
  • Updated the download links for the Reference Guide. If you want to update, delete the current files in the “doc” subdirectory and press F1 in Mumbai.
  • Updated the snapper script to v4.24

Changes for 3.0.1:

Breaking change: Any custom command that you set up on the toolbar will be gone.

  • Breaking change: -If you use a master password to encrypt connection passwords, you will loose all your stored passwords with this release. To prevent this, run your current version first and remove the master password, before updating to this version.

    Hi Marcus,
    Such a great tool !
    I am amazed at seeing what you did in Mumbai.
    Recently I was searching information about the Oracle Wait Interface and I found the snapper script which then led me to your website.
    Congratulations for such an easyness of use, for the nice GUI, for the way snapper has been included and its data now available in graphic form.
    A friend of mine asked me if Mumbai exists for Linux.

    Greetings from France

    Hi Marcus –

    I am wondering about the name. Mumbai is a famous city in INDIA. What made you to choose this name.

    Thanks for great tool

    Regards,

    • Hi Jagjeet!

      There’s really no special reason behind it… I just liked the name of the city and city names for computer applications prevent trademark problems.

      Cheers,

    Hello Marcus,

    Thanks for this awesome tools.. I was wondering how to use the putty and Winscp features ? I put the putty and winscp in my PATH variable but I can’t enable the putty login.. 😦

    • Good to hear you like it!

      The putty/WinSCP feature is not documented, sorry. You will have to edit the Mumbai.ini file to have the following entries:

      [PATHS]
      Putty=C:\Programme\PuTTY\putty.exe
      WinSCP=C:\Programme\WinSCP\WinSCP.exe

      This will only work if you entered a hostname on the “Easy Connect” page for this connection, even if you actually use a TNS alias.

    Hi Marcus,
    Great tool and I love the fact it integrates with snapper and putty. I have often thought of doing something similar, but it is much easier to think it about instead of actually doing it 😉

    I just seem to have one issue. When I select the Object browser with a non-privileged account I get the following error:
    ORA-00933: SQL command not properly ended.

    Everything works fine if I grant privileges on DBA_OBJECTS to my user or use an acount with dba privileges.

    Finally many thanks for sharing your work.
    Vince

  10. Hi Marcus,

    Fabulous tool. Very elegant design and very very useful. Thank you for this. I was working on Snapper and got redirected from Tanel’s blog. This is a great tool. Congrats and Thank you!.

    Marcus, Awesome changes to version 2.1.1.630. I was already able to identify a problem that i am trying to figure out for couple of day with the help of correlation. AWESOME…..

  12. I love this product. Can we expect a Linux version sometimes in the future? This is a Delphi compiled product and my main desktop is Linux X86-64. Having this on Linux would be a great plus.

  13. Hallo Marcus,

    hab mir mumbai gerade installiert und spiele damit rum …
    Sieht ja klasse aus auf den ersten Blick, vielen Dank !

    Hi Marcus,

    Just found out you added ASH info …. great stuff man.
    Keep up the good work.

  15. igor says:

    Hi, Marcus
    This application realy useful. I liked how you integrated snapper from Tanel Poder with graphical part, AWR reports, Statspack reports and ASH. Well done! Keep on improve the program!
    I see that program always hangs when I press ‘Refresh’ button in AWR section.
    Could you please fix it?

    Thanks!

    Best regards,
    Igor.

    Awesome tool … and I have not even enabled BASH on the server! I checked the statspack wait event graph and found that it would be cool if the x-axis labels (date and time) could be drawn with vertical orientation. As it is now you cannot really see any of those labels if you make this graph for a week or so with hourly snapshots.

    Regards,
    Robert

    • Hi Robert,

      good to hear you like it. The labels on the graph are really a limitation of the charting component I use. For now, you will have to help yourself with the tooltip hints over the data series showing the date and time. I now use another charting component, e.g. for the ASH Viewer and I’ll probably recode the SP/AWR stuff for this new charting component sometime.

      Cheers,
      Marcus

      • Robert says:

        Thanks for your comments … another thing you may improve with the SP graphing is to allow to draw the total wait times (per hour). For whatever reason you decided to take the unit ‘absolute wait time in microseconds per seconds elapsed’, its hard to map the resulting numbers to what really happens. I think the total wait times would be much more intuitive. The optical outcome would be perfectly the same, except that the numbers are more easily to understand.

        Example: SP report states 483 secs DB time and 194 seconds wait time for db file seq. read. Your graph says, its 53.855 microseconds at the same point in time. In my head this maps to 0,053 % which is really not much. But why is it graphed as such a dominant wait event? Because this wait time is 40,1 % of the total db time and so this is a major wait. Hope this helps.

        Regards,
        Robert

      • Following your example: 194 seconds wait time for db file seq. read in a one-hour (3600secs) interval means that 5,3% (not 0,053%) of the one hour wall-clock time were on this event. “53.855 microseconds per second” is just another way of saying this (1.000.000 msecs=1 sec).

        The reason for the normalized unit is that you can’t assume a uniform snapshot interval. There might be additional manual snapshots or times where you did e.g. 30 minutes snapshots. To show reasonable and comparable values the shown values are normalized to one second wall clock time and thus independent from the snapshot interval. The SP/AWR textual reports work on one start and one end snapshot and have the duration of the interval at the top (actually they only have the timestamps and the first thing I always do is to write down the number of seconds elapsed), so you can put the absolute values below into context. The graphs in Mumbai work over lots of snapshots and thus need to normalize the values.

        Regarding the question if this is a major wait event: If you have 10 seconds DB time within a one-hour-interval and 90% of these 10 seconds were on “DB File seq. read”, would this be a major wait event. It is a large share relatively to the DB Time, but would you be interested performance-wise in an event that took 9 seconds in a 3600secs interval (0,25%)? It probably depends on how the 10 seconds were spread over different sessions and different times, but I guess the short answer would be no.

  17. Vijay says:

    Is it possible to import AWR report from other database into Mumbai for analysis?

    • Marcus says:

      I’m not sure what you have in mind. What do you mean by “other database”? Mumbai needs to fetch the AWR data from the database where the AWR data is stored into memory and will show the analysis result. Mumbai does not store this data persistently/locally.
