Operating OnLine

Because tbcheck -pc derives its information directly from the tblspace, you
do not need to run the

UPDATE STATISTICS

statement to ensure that the

output is current.

Refer to

 for further information about the tbcheck -pc display.

Use these options to track available disk space. The Dbspaces menu, Info
option describes the mirror status of each dbspace chunk.

From

DB-M

onitor, select the Status menu, Spaces option.

The first screen display lists the dbspace ID number, the name of the dbspace,
the number of assigned chunks, and the mirroring status of the dbspace. If an
asterisk appears next to the

Mirror

field, one of the chunks in this dbspace is

down. Select the dbspace that you want to monitor.

The second screen display lists the following chunk information for each
dbspace:

■

Chunk ID

■

Chunk pathname and offset

■

Mirror status flags

■

Pages in the chunk

■

Number of used disk pages in the chunk

If a chunk is mirrored, both the primary chunk and the mirror chunk share
the same chunk ID number.
