Index Creation on extended tablesSummaryAfter creating a index via Tables & Columns we are not able to see the index created. The reason could be because the table is extended from another table per example cmdb_ci_kvm_storage_pool extends from cmdb_ci that extends for cmdb. In this case the index will be created on cmdb (or cmdb$par1 depending where the column is.) In this case we need to check the Storage Column Alias (sys_storage_alias). TIP: Before adding an index check if an index was already created, by default if was already created the platform will not try to create a new.InstructionsHere are the steps to check: 1. Create an index on a extended tables (per example cmdb_ci_kvm_storage_pool) 2. We go to tables to check if the index is present on the table (in this case will not be present): 3. The next step is to go to Storage Column Alias (sys_storage_alias) and find the column. In this table we will see on which physical table is our column present (in this example is on cmdb$par1 and has the name a_int_14. 4. If we check in Tables for cmdb$par1 (it is better to search). 5. We can see that the index is present:
