Connection and behavior inventory
| ADO/OLE DB | Provider version, connection properties, cursor and transaction behavior. |
|---|---|
| ODBC | 32-bit driver/DSN, authentication and SQL dialect. |
| Stored procedures | Parameter types/order, return values and result-set expectations. |
| Schema coupling | Column order/types, identity values, triggers and compatibility level. |
Controlled modernization
- Capture connection/error evidence and database version.
- Inventory inline SQL and stored-procedure contracts.
- Test authentication and drivers from a clean 32-bit client environment.
- Characterize transaction, timeout and concurrency behavior.
- Upgrade provider, server or application in separate reversible stages.
Use ODBC troubleshooting, database modernization, dependency analysis and the pillar.
Provide source/build, provider/driver, connection method, schema/procedures and representative transactions.
