Verifies and repairs the Tivoli database.

Syntax

wchkdb [-o outfile] [-t] [-u] [-x] -f infile

wchkdb [-o outfile] [-t] [-u] [-x] -i

wchkdb [-o outfile] [-t] [-u] [-x] object...

Description

The wchkdb command verifies and repairs problems in the Tivoli database. This command does not affect any system files; it only modifies resources within the Tivoli region.

Without the -u option, wchkdb only verifies the database and reports discrepancies to standard output or, optionally, to an output file if the -o option is used. The output file can later be passed to wchkdb with the -u and -f options to correct the discrepancies.

The -u option attempts to find and fix any database discrepancies. The -f option reads input from an output file generated in a previous run of wchkdb. All objects in the infile are checked. The -i option reads a list of objects from standard input. You can also specify a list of objects on the command line. If no input options or object references are provided, all objects in the database are checked.

The -x option enables verification across Tivoli region boundaries. Without this option, only resources within the current region are verified and repaired.

In a high-activity Tivoli environment, it can be advantageous to place a Tivoli management region in maintenance mode, thereby stopping all active Tivoli processes. For more information about placing a Tivoli region in maintenance mode, see Tivoli Management Framework Maintenance and Troubleshooting Guide.

Options

-f infile: Reads the specified input file, which was created during a previous database check, and checks only those objects listed in the file. Only objects that failed during the previous run are included in the file.
-i: Reads a list of objects from standard input. The list consists of object IDs, object names, or both (each separated by a space).
-o outfile: Writes a binary version of the displayed output to the specified file name.
-t: Verifies and repairs object references in only the Tivoli server database.
-u: Updates the database, fixing any discrepancies found in the Tivoli resource database.
-x: Verifies and repairs object references across region boundaries.
object...: Specifies an object ID or object name to be verified and repaired.

Authorization

senior or super

Return Values

0: Indicates that the operation started successfully.
nonzero: Indicates that the operation did not start successfully, either because of a syntax error or because the object dispatcher is not available.

Examples

The following example verifies and, if needed, repairs the Tivoli database. Object references are checked across Tivoli region boundaries.
```
wchkdb -u -x
```
The following example verifies object references in the current Tivoli region only. No changes are made to the Tivoli database. Problems , however, are displayed to standard output and written to the /tmp/check.out binary output file.
```
wchkdb -o /tmp/check.out
```
The following example reads the results from a previous run of wchkdb invocation (/tmp/check.out) and updates the Tivoli database as needed:
```
wchkdb -u -f /tmp/check.out
```
