The verify-index BASIC program verifies the integrity of one or all B-tree indexes in a specified file name.
verify-index dict file.reference a.code{(options)}
verify-index dict file.reference attribute.defining.item{(options)}
verify-index dict file.reference* {(options)}
verify-index ?
| a.code | Specifies the a processing code to be used
in forming the keys to the index. The processing code must include an attribute number. |
|
| * | Designates all indexes. | |
| ? | Displays online help for this command. | |
| options | a | Verifies all indexes in the account or system. |
| c | Compares the file to the index only. | |
| e | Creates an error log. When this option is specified, the command prompts for the error log file and item (VME only). |
|
| f | Displays link and node-IDs during verification (VME only). | |
| i | Displays item-IDs (VME only). | |
| k | Verifies links and nodes (VME only). | |
| l | Locks each data item as it is verified (VME only). | |
| m | Suppresses all messages (VME only). | |
| n | The n variable is an integer specifying a limit for the number of consecutive errors that can occur during index verification before moving on to the next index or file (FSI only). | |
| n | Affects output to the terminal only. Prevents output from pausing at the end of each (terminal) page of output. | |
| o | Reports missing item-IDs and locates items indexed in the wrong place. While using this option makes the process run slower, it increases the reliability and effectiveness of the process (VME only). |
|
| p | Directs the report to the system printer via the spooler. | |
| r | Inhibits index recreation when there is a link error (VME only). | |
| s | Suppresses display of item counter (VME only). | |
| v | Verifies that the data exists for the given indexes. This is used in the cases where the index contains pointers to item-IDs that have been deleted; this is not typical (VME only). |
|
| x | Suppresses automatic fix of bad indexes. This option produces a report only (VME only). | |
| z | Stops processing after link and node verification (VME only). | |
With no options specified, the process examines each item in the file and verifies each of the indexes specified. A counter displays on the screen for monitoring the progress of the verify-index command.
To verify a single index, the TCL casing set by the case command must match the casing of the index.
Example 1
The following example verifies the index on attribute 1 of the entity file.
verify-index entity a1
Example 2
The following example verifies all indexes in the entity file.
verify-index entity * (o
