Re: CMDB 8.1 Index on Name Field
I am pretty sure I have seen an answer from a BMC person (Doug maybe?) why the Name field isn't indexed out of the box. If I remember correctly it was something along the line that they are leaving it up to us to decided if we need indexing or not. Each organization may have different indexing needs based on how the CMDB is used and the attributes an organization chooses to use.

Re: CMDB 8.1 Index on Name Field
Hi, There is nothing mention about indexing in CMDB 8.1 to improve performance. We can add index for better performance as per doc provided by BMC. - Indexing classes can reduce database query time. Index attributes that: *You expect users to query frequently. *Are used by discovery applications to identify CIs. *Are used in reconciliation identification rules. For more information about identification rules, see the BMC Atrium CMDB 8.1 Normalization and Reconciliation Guide. If you create an index for a Character attribute, you can save query time by setting the QBE Match characteristic of that field to Leading or Equal instead of Anywhere. Use the Indexes section on the General tab of the CI Class and Relationship Class dialog boxes to specify the indexes for a class. You can specify indexes on noninherited attributes only. If an attribute is inherited form a superclass, you must specify the index for that attribute on the superclass. Display-only attributes cannot be indexed, because no values are stored for them. To combine multiple attributes into a composite index, specify as many as 16 attributes per composite index. The sum of all attribute lengths in a single index must be fewer than or equal to 255 bytes, so Diary attributes and Character attributes larger than 255 bytes cannot be indexed -- Regards, Pawan Vyom Labs Pvt.

Re: CMDB 8.1 Index on Name Field
Better treat everything from low level, start by one Class, ensure the legacy index in regular form, then upgrade to 8.1 and check the class-index in the new regular form or join.

Re: CMDB 8.1 Index on Name Field
Carl, Thanks for the links. I had seen them awhile ago so it was good to review them. I didn't see anything regarding the name field being indexed though. I'm hoping to hear from someone with a similar environment, without an index on the name field, that can say searching is fantastic. Or to give an explanation as to why searching by name might be the wrong thing for my users to be doing (after all, wouldn't BMC have included an index on that field if it was meant to be a common search criteria?) On a side note... In 8.1, they moved a lot of attributes out of the CMDB and into Asset Management (on the AST:Attributes form). One of them was the "Floor" attribute. Oddly, they didn't move the "Room" attribute or the other location info. That seems strange as well.
