Introduction
If you work with Indexing Service (CISVC) in Microsoft Windows 2000, you might be interested in having a periodic report emailed to you from the server.
At a previous job, I made extensive use of Indexing Service (CISVC) for keyword searching in the database. You might wonder why I didn't just use the SQL Full Text Indexing.. we did, but found the performance and controlling the process not adequate.
Details
The key component used to access the indexing service is:
AdminIndexServer (ProgID: Microsoft.ISAdm)
This component provides access to a number of objects and methods that are used to query the status of the indexing service and its catalogs.
Objects, methods and properties used:
AdminIndexServer (ProgID: Microsoft.ISAdm)
GetCatalogByName (returns CatAdm object)
CatAdm
CatalogName (gets the current catalog name) IsUpToDate IsCatalogRunning IsCatalogPaused IsCatalogStopped IndexSize TotalDocumentCount DocumentsToFilter PctMergeComplete QueryCount StateInfo (* bitwise lookup, below)
I've chosen to only report on the status of specific index catalogs, but you can loop through all of the index catalogs by using the methods FindFirstCatalog and FindNextCatalog.
Note that the status of the catalog is given in such a way that you can use bitwise operations to get multiple statuses from the one return value. Here's a list of the constants I've used to get the status of the indexing service catalog:
CI_STATE_SHADOW_MERGE = 1 '0x1 CI_STATE_MASTER_MERGE = 2 '0x2 CI_STATE_CONTENT_SCAN_REQUIRED = 4 '0x4 CI_STATE_ANNEALING_MERGE = 8 '0x8 CI_STATE_RECOVERING = 32 '0x20 CI_STATE_INDEX_MIGRATION_MERGE = 64 '0x40 CI_STATE_LOW_MEMORY = 128 '0x80 CI_STATE_HIGH_IO = 256 '0x100 CI_STATE_MASTER_MERGE_PAUSED = 512 '0x200 CI_STATE_READ_ONLY = 1024 '0x400 CI_STATE_BATTERY_POWER = 2048 '0x800 CI_STATE_USER_ACTIVE = 4096 '0x1000 CI_STATE_STARTING = 8192 '0x2000 CI_STATE_READING_USNS = 16384 '0x4000
I hope this is useful for anyone having to deal with indexing service. I had many painful hours as I dealt with some quirk.
I think it's fairly straight forward to understand, I've tried to keep it simple (I'm sure someone has a witty quip to insert here... something about being simple ;-)).
History
- 19th June, 2006: Initial post
Software developer by trade.. well I used to be, now I'm in that grey area where who knows what I do. But I still use software development in one way or another quite often. I actually work with
osCommerce CRE Loaded for our online stores, and I have a couple tips on my
website.
Finished my 'rocks for jocks' degree after 10+ years (physical geography). And I have to say that I use the knowledge and skills that I obtained while getting my degree every day... not! But if a glacier wanders through my neck of the woods I'm sure I'll be able answer everyone's questions.
Not that I'm a naturalist, but I love looking at and reading about interesting stuff in nature. For example, I took a photo of
ants and aphids in a symbiotic relationship. You might be familiar with this relationship, but it's very cool.. though somewhat disturbing if you think of it.
And I should have been an engineer.. and not the train driving ones! Oh well, too late now.
