From time to time it is possible for an index file to fail and t28 is unable to automatically resolve. A problem with an index file can result in t28 having difficulty finding specific records or becoming slow and unresponsive. In this scenario the Data File Re-Index should be used.
During the file re-index it is important no other user is logged into t28.
To perform the re-index go to Maintain, then click the Tools drop down menu and select File Re-Index
Once you have selected File Re-Index you will see the Data File Re-Index window.
From here you can re-index individual tables by highlighting the table name and clicking Rebuild, or re-index all tables by clicking Do All. Once you have re-indexed all the tables you will receive confirmation this has been completed.
Clicking OK will complete the File Re-Index.
