At this point the validation does not continue. If you receive this type of error during a validation, enable the Ignore Checksum Errors option and run the validation again to look for other

errors. Restore the backup that you created prior to the validation. If there has been any activity on the database since the beginning of the validation, you must shut down the database, back it up, and restore to repair the checksum errors. After restoring the database, validate it again with the Ignore Checksum Errors option off, to confirm that the errors have been repaired. Note: Checksums are maintained only on the Windows NT, Netware NLM, and Local Server versions of InterBase. UNIX versions do not maintain checksums.

This is probably preventing online backups from running, too. First of all, here is a really good article that will help you understand what is (or may have happened) to your database. Based on what you put in your posting, I would have expected to see a -1018 error, but I did not. I'm hoping that this is all relevant to you.Understanding and analyz

certain circumstances, you are advised to validate the database to check for corruption. The times you would check are: When an application receives a database corrupt error message. When a backup fails to complete without errors. If an application aborts rather than shutting down cleanly. On demand - when the SYSDBA decides to check the database. Note Database validation requires that you have exclusive access to the database. To prevent other users from accessing the database while you validate it, use the gfix -shut command to shutdown the database. When a database is validated the following checks are made and corrected by default: Orphan pages are returned to free space. This updates the database. Pages that have been misallocated are reported. Corrupt data structures are reported. There are options to perform further, more intensive, validation and these are discussed below. Default Validation The command to carry out default database validation is: gfix -v[alidate] database_name This command validates the database and makes updates to it when any orphan pages are found. An orphan page is one which was allocated for use by a transaction that subsequently failed, for example, when the application aborted. In this case, committed data is safe but uncommitted data will have been rolled back. The page appears to have been allocated for use, but is unused. This option updates the database and fixes any corrupted structures. Full Validation By default, validation works at page level. If no need to go deeper and validate at the record level as well, the command to do this is: gfix -v[alidate] -full database_name using this option will validate, report and update at both page and record level. Any corrupted structures etc will be fixed. Read-only Validation As explained above, a validation of a database will actually validate and update the database structures to, hopefully, return the database to a working state. However, you may not want this to happen and in this case, you would perform a read only validation which simply reports any problem areas and does not make any changes to the database. To carry out a read only validation, simply supply the -n[o_update] option to whichever command line you are using for the validation. To perform a full validation, at record and page level, but in reporting mode only, use the following command: gfix -v[alidate] -full -n[o_update] database_name On the other hand, to stay at page level validation only, the command would be: gfix -v[alidate] -n[o_upda
