Installation Queries - HP UCMDB 10.3X

Hello All,

I have some queries regarding the installation of HP UCMDB 10.3X:

>> Configuration of Database

We are using MS-SQL as database for HP UCMDB, during the installation there is an option to check "Multi-Tenancy" for database. Is it reccomended or not to enable the multi-tenant mode.

>> Installation of Data Flow Probe

a) Is it reccomended to install it on "Separate Mode' or not. How to decide whether shall I take separate mode or not

b) What is reccomended data flow probe memory size to be provided during installation

c) Do DFP still need embeded PostreSQL for performing interim operations on discovered data, I am considering MS-SQL as database for HP UCMDB

d) During installation, it gives an option to provide password for "sysadmin" which can be used to log in to JMX console. But during installation of UCMDB, I have already provided the credentials for "sysadmin". DFP is installed on separte machine.

e) What is the use Account configuration for Uploading Scan File.

Thanks in Advance!!!

Re: Installation Queries - HP UCMDB 10.3X

Hello there,

Multi-tenancy is a concept to have the same data consumed by users based on some rules. 

http://cmshelpcenter.saas.hp.com/CMS/10.22/ucmdb-docs/docs/eng/doc_lib/Content/admin/MultiTenUCMDB_c_Overview.htm

It's different than multi-customers and it's much better actually.

http://cmshelpcenter.saas.hp.com/CMS/10.22/ucmdb-docs/docs/eng/doc_lib/Content/admin/MultiTenUCMDB_c_architecture_MTvsMC.htm

a) Separate-mode for the probe deployment implies the Probe Gateway and the robe Manager to run in separate JVMs or separate machines as it was possible a long time ago. It's a legacy feature inherited over time. It was useful up until 9.05 when we used JRE6 and each JVM was bound to the 32bit memory restrictions. Now, unless you want to complicate your architecture, there's no actual benefit in using Separate mode. Just a handful of customers may still use this feature.

b) 10.22 was the first release with an actual sizing guide.. Over time it was improved to contain more details. You can find here --> https://docs.microfocus.com/UCMDB/10.33/ucmdb-docs/docs/eng/doc_lib/Content/Sizing_Guide.htm?Highlight=sizing%20guide

c) Probe DB is a separate DB in the UCMDB architecture. Starting with UCMDB 10.10 we use as an embedded probe DB the Postgresql option. It will run only on localhost and it's just enough for what the probe needs to do. We don't support any other type of Probe DB

d) Although both UCMDB server and DFP have an internal username called sysadmin, don't confuse the 2 accounts because they are defined on 2 distinct components and they will never interact with each other. It's by design to handle them as unique accounts.

e) read the note at the bottom of https://docs.microfocus.com/UCMDB/10.33/ucmdb-docs/docs/eng/doc_lib/Content/dfm/ScanGen_t_handle_scanfiles.htm?Highlight=Uploading%20Scan%20File

 

have fun and quiet logs.

Kind regards,

Re: Installation Queries - HP UCMDB 10.3X

Hi Bogdan,

With respect to the multi-tenant architecture, as you mentioned the data can be consumed by users based on some rules.

So, with respect to the discovering the infrastructure using UCMDB, will it be all same ?

The only difference, I can understand is the visibility of data in the multi-tenant will be on the basis of some rules.

How much overhead is required to manage the tenants and users for discovery and What is the impact if I don't opt for the multi-tenant and control the access to the data using users, roles and groups.

Thanks in Advance!!!

Re: Installation Queries - HP UCMDB 10.3X

Multi-tenancy is to be preferred instead of CLA.

After doing discovery, it all boils down to assigning the proper tenants to the needed CIs. This can be done via special enrichments which are called tenant association rules.

It will take a little bit of time until you get used with them and you find your perfect formula.

Re: Installation Queries - HP UCMDB 10.3X

I suggest having a clear, long term reason for using multi tenancy. Using multi-tenance also disables the use of UCMDB Browser CI Access Control. You can undo or switch from multi tenancy. So read about it, develop your UCMDB architecture and process/workflow(s) before deciding.

Pretty much same goes for the probe, if you're not familiar with the Data Flow Probe and the Probe Manager and Probe Gateway and do not have a clear, long term case for using separate mode then do not use separate mode.
