Inventory Discovery By Scanner is failing
This issue happens due to size of column named "CI" in LOA table in UCMDB database. This field basically store the name of discovery job as value which you usually see in Last Discovered by field in CI property. If length of this value exceeds the pre-defined size of the field, you started getting the error in Inventory Scan.
To resolve, please follow below steps.
1. Stop UCMDB server
2. Change the column size in DB
For Oracle: ALTER TABLE LOA MODIFY CI varchar(255)
For MS-SQL: ALTER TABLE LOA ALTER COLUMN CI varchar(255)
3. Start the UCMDB Server.
4. Run the discovery again.
Note - It is recommended to take DB backup prior to change (Step 2).
