HANA DB - what if db goes down, how to monitor/alerting using Studio

I have configured mail alerts for my hana db instance (for certain / all events).
If I stop my db (instance) I still do not get any alerts because I assume there are no specific events to be set for monitoring/alerting purpose in case hana db itself goes down. Is this a normal behavior in HANA as the db itself has monitoring/alerting capability? If yes then how will a DBA get to know if the db goes down.
Please correct me if I am missing something while setting alerting mechanism. 

Also would want to know if there are issues with the latest rev. SP7 w.r.t alerts and hdbstatisticsserver service under Landscape?
I have observed the hdbstatisticsserver (and daemon.ini) doesnt come up on its own after db instance is restarted.
FYI: I have HANA Instance on Linux VM (sandbox).

  • Lookup definition - what it is for? how it could be used?

    Dear All,
    I have a few questions regarding lookup definition.
    1.What lookups are for?How they can be used?
    2.I noticed a lot of out of the box pre-configured lookups are empty. Why? Hmmmm.... Does not make any sense...
    Example,
    Lookup.AD.FieldsForValidation
    3. It looks like Group field might be empty. Why? Is this when lookup definition used by more than 1 form?
    4. What is the naming convention for code field?
    I carefully reviewed documentation below:
    http://download.oracle.com/docs/cd/B32386_01/generic.902/b32143/oimadm.htm#BABIBJAF
    I would appreciate your feedback

    My apologies I think I confused you and my question was not clear. (80% already answered by Kevin. Thank you!)
    Please let me try to rephrase this for you. (I appreciate your help and guidance!!!!!!)
    Lookups are stored in the OIM database .
    The purpose:
    1. Allow user to select a value from the list.
    2. meta data storage (configuration information for adapters, triggers for events, list of available countries, etc. ).Lookups are used by connectors or OIM application itself.
    How they can be populated:
    1. Through API within your custom task.
    2. Out of the box connectors (Lookups for Groups, Organization in AD adapter)
    3. Manually by creating lookup definition from Design console.
    How they can be used:
    1. Set up a query code for the field directly on the Form Designer (Properties tab of the form). FYI There are a few meta link articles regarding lookup manipulation.
    2. through FormMetaData.xml configuration.
    What is still unclear for me:
    I am planning to create a custom lookup that will contain information that will be used for provisioning.
    1. Is there a naming convension for Code field that I have to follow for custom lookup definition? Some of the existing out of the box lookups start with Lookup. , some does not..... They follow some kind of a hierarchy. For example, Group.Object Permissions.Allow Delete
    2. Why group field sometimes populated, sometimes not? (It is not required for custom lookup definition)
    3. How to filter lookup data through API?

  • "What Size" results question. How can I locate used GB not appearing on HD?

    My Version Tracker "What Size" results are as follows:
    / - on disk 91.4 GB
    Capacity 465 GB
    Used 145 GB
    Available 320 GB
    71.1 GB Users
    8.61 GB Applications
    6.34 GB Library
    2.67 GB username
    1.43 GB System
    I have about 30 GB of songs, 5 GB of Pictures, and 30 GB of movies. So I am confident that the "Users" total (71.1 GB) is in keeping with what I have used. (And Users, Applications, Library, username, and System all equal what is "on disk, 91.4 GB.")
    What I am wondering is, how can I locate the unaccounted for 53.6 GB? (Which is 91.4 subtracted from the "Used 145 GB.")
    I have been unsuccessful in finding any searches related to this subject that I can use. I found a couple about using Terminal, however, I would need step by step procedures for that.
    Any ideas, articles, or threads anyone can point me to?

    Hi jpwill,
    First of all, always keep in mind the double standard problem that prevents from being able to make straight, simple, easy counts. See:
    - (KB article # 30065) Macintosh Hard Disk: Is It Missing Space?
    Then, WhatSize should be run separately from each user account, as you cannot use it to spy on the others, it doesn't take into account the others' files.
    Also: some system files like VM have a fluctuating size. Quit as many apps as you can and test if several measurements give different results.
    WhatSize is able to show (one user's) every folder and every file. Use its different ways to show results, and detect the "strange" sizes firstly from what should be expected.
    It is very possible that a file has grown huge for some reason.
    Let us know if you have a question about some particular files!

  • What is RSS feeds and how it can be used in Portal.

    Hi All,
    Please someone have any idea , "How can we use the RSS feeds in portal " . This is a new concept for me , so I m totally aliegn for this topic.
    Thanks in advance.
    Mayank kumar saxena

    Hi,
    We already done some development based on rss feed, but it was not for any portal content.
    We generated these files outside portal then scheduled to upload to km folder.
    In portal, we have to use km repostitory to store these file. By setting these folders for anonymous access, user can subsribe to this Feed, which will get updated with out login.
    The basic requirement to develope rss feed is to understand the xml format. With the help of internet you can learn, its simple.
    <?xml version="1.0" ?>
    <rss version="2.0">
    <channel>

  • What are Struts?? How they can be Used?

    HI anyone
    what are struts? are they different from JSP?
    tks

    You should refer to the Struts FAQ which starts with questions like yours:
    http://jakarta.apache.org/struts/userGuide/kickstart.html
    Bottom line is that Struts I believe is designed to enforce more disciplined coding which makes code easier to read and maintain. JSP conversely can be misused wherein developers fill up JSP pages with Java code and there is no separation of presentation from business logic.

  • Anyone know how to monitor power used on USB Port?

    I have an external quickertek usb wireless device that keeps shutting down my Macbook pro. It runs fine for a few days and then locks the entire system up. Quicktek made me a special device with an external power adapter thinking the problem was the USB port being asked for more power than it could deliver but the system is still crashing. I'd like to monitor my power output on that single USB port to see if the new device is really working properly but not sure how to measure power consumption on a usb.
    Can anyone tell me if this is possible and if so how?
    Thanks,
    glenn

    thanks guys, I'm not sure how accurate the actual current power being used is as it seems to always say 500ma but I'll play around with it and see if I can get it to work for me.
    glenn
    Remember that 500 ma is the limit, so if a device attempts to draw more, it most likely will be current-limited at .5A.
    At least it's a start.

  • How to schedule a service to run before network goes down

    Hi
    I wrote a new smf service and added it to the repository.
    When running with "stop" (when the system goes down) it sends an alert to another machine.
    My question is :
    How can I schedule that service to run just before network services go down?
    another question, how can I schedule another service to run just BEFORE system is getting down?
    Many Thanks
    --me2unix                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               

    Dependencies appear to be really written and tested on the boot side, but they should work properly going down as well.
    My first assumption is that you'd make a dependency on the network for your service. So it should be started after the network starts, and will wait for your service to quit before trying to shut down the network.
    Now this would only apply to normal shutdowns. Also, there are mulitple services on the box that have network affects. You may need to read through several to understand their purpose and interaction to pick the correct one for your use. Probably the milestone/network will be the best choice.

    Your iPad cannot have a virus - there is no malware that can affect an iPad, unless you have jailbroken it - so that's not the problem.

  • My battery goes down, even without using the iPad and locking it

    I've got an iPad 2 with the smart cover, but it's battery goes down quite quickly, even without using it and having locked it.

    When the screen is dark, it's still on, unless you've completely powered down.  So, things that can cause battery drain (just to name a few) could include:
    1.  Searching for a WiFi or 3G signal if not locked on to one.......
    2.  Having push on for mail, causes the iPad to seek new mail messages, eating up battery power
    3.  Having location services on can eat up battery power
    If you want to preserve the battery, shut it down when it's not going to be used for a few hours.  And if you've got a WiFi version and you're not in one place, turn WiFi off, so your iPad isn't constantly searching for a WiFi signal.

  • How to handle error when in middle of processing of data, target DB goes down

    I have large amounts of data ( for e.g.- 1000 records). It is writing to a DB target table. At the middle of processing of 500 th record, target DB goes down.
    What will happen to the data after 500??
    In which table will the data after 500 th record be stored?
    After target DB comes up how will the data( from 501 th record) be fetched so that no data loss takes place..
    Thanks,

    Anindya,
    ODI's performance is pretty good, because in fact there is no "ODI Performance". The performance will be as good as your enviroment performance + a good load strategy. I've been working in several ODI projects with gigantic volumes, with no performance issues.
    There is no such thing as "remaining un-inserted data". All data being inserted remains in the I$ table until the end of the process. ODI does not automatically control inserted/uniserted data, so, be carefull if you will implement a commit in your process. You will have to implement your process in order to flag the data that has been comitted, and where clauses to ignore them when the load is aborted/restarted.
    Also you will have to use a row-by-row processing which will dramatically decrease your performance.
    Please let me know if that helps!
