Web Site on HP Open View - Tips & Tricks

Dear All,

I created a site, where i am publishing all the tips & tricks and other info about HP Openview products.

Please visit :
http://geocities.com/helponhpopenview

If you have any documents, ppt which you want to share, you are most welcome. Also, please let me know the quality of the stuffs, that you see in this site. (This site is in an infant state, need your help for improvements)

My idea is to provide a single point, where you will get most of the questions answered.

Re: Web Site on HP Open View - Tips & Tricks

Hello Ashly,

1. The ability to add an entity to shortcut bar by providing its oid isn't my discovery. I merely made this fact known. I learned about this by Tom Marcus

2. Another useful tip (at least I think so) is the method I found to distinguish between Scheduled Task, so I some one wish to delete one or more scheduled tasks, to be able to identify what rows from REP_JAVAOBJECTS should delete. You can find this at http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1059010

I didn't have the time to create a doc that contains detailed instructions but anyone who has a fair knowledge of OVSD, MS EXCEL and MS ACCESS can do this easily.

Re: Web Site on HP Open View - Tips & Tricks

hi George,

Changes are done.
And, as you said, i don't think there should be detailed DOC for removing the scheduled jobs. Normally this kind of requests will be carried out by someone who has fair knolodge in SD,Excel and SQL. So, i think we can avoid that.

Do you have anything to add to Speed Up the SD ? I am planning to add few more things at the client side (like reduce the number of fields and tabs etc..

Re: Web Site on HP Open View - Tips & Tricks

Hello again,

Actually I had wrote in some posts the practice I follow to speed up client, but the search is quite problematic so i'll post it here again.

1. Avoid having too many fields of entity reference and entity reference set type in the most used forms.

Examples of entity reference set: Service Calls, Changes, Incidents, Problems, Workorders on Configuration Items, Child Organizations in ORGS etc.

Entity reference fields are Codes (custom or built-in), persons, workgroups etc.

2. For items with very large volume of entries, besides setting query limits through Presentation/Search, fields most commonly used as criteria in search/view filters should be indexed at the db level. Multiple indexes may be needed.

For example, We have about 2500000 configuration items and 600000 persons. An advanced find using a non indexed field as filter may take as long as several minutes to be completed. Indexing together fields that are used in filters reduce search/time to present a view to seconds.

3. For items with large volume of entries, avoid presenting too many entity reference fields in the views. Not only the views on client but the views that are "embedded" in forms for entity set relations (example CI users, Used services etc).

4. For items with large volume of entries do not use custom fields as primary keys for Data Exchange tasks. Use "searchcode", "source-id" or even id if possible.

5. In heavy views avoid having calculated fields (like remaining duration).

Re: Web Site on HP Open View - Tips & Tricks

Just an small addition to Data Exchange: Fields that are used as primary keys in D.E. tasks should ALWAYS be indexed at the db level. Searchcode is, but source id isn't!

Sometimes multiple indexes are required: For example Source ID in one index and Source ID and OID in another index.

Re: Web Site on HP Open View - Tips & Tricks

Hi,
This tip may be known to old timers but for someone new to service desk I hope it is useful.
*********************************************
Usually all service departments conduct a customer satisfaction survey or feedback for the services they are offering to their end users or customers. Unfortunately this feature is not there by default in service desk.
But Service desk can be customized to enable this. The procedure would involve following steps:
1. Enable some custom fields to define the feedback questions and also to capture customer's inputs. (Ex: using Code or Text fields).
2. Customize service pages to include a new jsp which acts like a feedback form. This form would contain all the custom fields defined above and also method to save these.
3. Customize ViewEditServiceCall.jsp to call the new form on certain condition (ex: When the status of service call is changed to Resolved.)
4. In the resolution emails request users to login to service pages and confirm the solution and provide their feedback. When user logs in he/she will see a link to provide feedback (this will open the Feedback form).
5. Modify / create views in database to report on the feedback collected.
6. Create reports to display customer feedback received on a weekly/monthly basis.

Re: Web Site on HP Open View - Tips & Tricks

Ashly,

I've had a look at your site, it looks good the quality of the stuff there is quite high. I'll be visiting again and reading more when I get time!

I replied to a post a while ago regarding Service Manager 7. I offered a PowerPoint Presentation of slides etc from the HP Seminar on SM7.

The zipped file is 14Mb. I have been swamped with requests to email the file and I've tried to send it to them all. Lots of the emails fail because of the file size.

Would you be able to host the file on your website?

If so please email me at peter.dent@nhs.net and I'll send you the file.

Also what else are you looking for, I have some documents which I have created which explain how to do stuff, such as getting data from an Excel sheet and importing into HPOV 4.5. I know its in the manual but this is hopefully easier to understand?

Would that sort of thing be of interest?

Lastly, on the HPOV page on your site, there are titles such as "How to check the DB of your Service Desk", but they are just text. They are not hyperlinks. Is this in development or is there some kind of error somewhere?

Thanks
Peter

About the other stuffs : Please rush them to me.....i am sure there are a lot of people who can use it....

Regarding "Checking DB" etc.. ::- I am yet to write in those topics. Thanks for reminding me and waking me up!!!!

Re: Web Site on HP Open View - Tips & Tricks

Ashly,

The slides about SM7 were received via email from HP themselves and they didn't say anything about not passing on the information, either in the email or in the seminar which I attended.

I doon't think there's anything in their which is confidential, its just product information. I think you'd be doing them a favour, I've passed it to about 50 people so far.

I would send you the documentation but, I don't have an email adderss to send it to?

I could post the docs here but that kind of defeats the purpose of your website and there's a 1Mb limit for attachments.

Have you an email address that I can send to?

Re: Web Site on HP Open View - Tips & Tricks

hi Peter,

Please send them to ashlyak@gmail.com

Meanwhile, let me check the PPTs that you send again. Do you have the e-mail ID of any of the HP People who did the presentation ? So that we can send them an e-mail and then publish ?

Re: Web Site on HP Open View - Tips & Tricks

Hey Ashly,

great idea with the site, thought you might want to add some info about finding deserialised rules, see the attached executeable plus the instructions.
This needs to be run directly on the app server using the system account as the default account

Re: Web Site on HP Open View - Tips & Tricks

Hi,

here is a tip on setting the java memory instead of using the defaults

-XX:MaxNewSize=64M -XX:NewSize=64M â Xms200M -Xmx1000M

- make sure that the sum of Xms (initial heap size) for all application servers running on a single physical machine remains clearly below the available memory (preferrably below 50 % of the memory)
- to assure that there will never be a shortage of memory, make sure the sum of Xmx (maximum heap size) for all application servers running on a single physical machine does not exceed the available memory
- make sure that NewSize is smaller than Xms, and MaxNewSize is smaller than Xmx
- setting NewSize to the same value as MaxNewSize assures the JVM does not resize its youngest generation, and should therefore result in a better performance.

Re: Web Site on HP Open View - Tips & Tricks

Ashly,

I will send you some documentation, promise.

Mark,
Thanks for the info on the memory settings. I have never understood what those settings do, I know they control how much memory is allocated to the Java VM but that's about it.

Would you consider creating a document to explain what they each do and their relationship to each other? In laymanâ s terms please?

I will create a new thread of you like so as I can assign points, or Ashly could award points here?

Thanks

Re: Web Site on HP Open View - Tips & Tricks

Hi Peter,

the following should help

Have a read of the following:

http://java.sun.com/docs/hotspot/gc/

As a general guideline, set -XX:NewSize= to one third of the amount of memory
allocated for one JVM, and set -XX:MaxNewSize= to two thirds of the same memory
allocation.

-XX:MaxNewSize=64M -XX:NewSize=64M â??Xms200M -Xmx1000M

- make sure that the sum of Xms (initial heap size) for all application servers running on a single physical machine remains clearly below the available memory (preferrably below 50 % of the memory)

- to assure that there will never be a shortage of memory, make sure the sum of Xmx (maximum heap size) for all application servers running on a single physical machine does not exceed the available memory

- make sure that NewSize is smaller than Xms, and MaxNewSize is smaller than Xmx

- setting NewSize to the same value as MaxNewSize assures the JVM does not resize its youngest generation, and should therefore result in a better performance.

Re: Web Site on HP Open View - Tips & Tricks

Hello Ashly,

wouldn't it be a nice idea to ask this famous SM7 presentation and share it on your web site.

I've tried to have a copy of it but unfortunately I never received it. Could someone be so kind and send it to Ashly so that the presentation can be shared like the tip and tricks are?

Rgds,
Michel

Re: Web Site on HP Open View - Tips & Tricks

Peter :: Points are taken careâ ¦. ï Thank you Mark

Michel :: I have seen the PPT, and it says â HP Confidentialâ so, I am afraid to publish it, unless I get am able to get in touch with a HP person and get permission to publish the sameâ ¦

Thank you ALL!!! I am working on making the site more good looking, all the new tips will be published on the new site, sorry for the delay!!
Please let me know, if you would like to see any changesâ ¦I will try my level best to add/remove them!!
