Large Databases

Running the Script

58
A database index named
added to the tmdb.tier000files% and tmdb.tier001files% tables upon
starting TSM for the first time after upgrading to specific StorNext 5
releases.
StorNext 5 Releases affected: 5.0.1, 5.1, and 5.1.1
Upgrading from: 4.3.2, 4.3.3, 4.7.0, 4.7.0.1, 4.7.1, 4.7.2, and the initial
release of StorNext 5.
Note: This does not apply to direct upgrades from StorNext 5 Release
5.0.1 to StorNext 5 Release 5.1 or later. So do not use the script
below for these upgrades.
This index improves the performance of certain operations such as
truncation policies. However, the creation of this index can take multiple
hours for very large databases. TSM will be unavailable after upgrading
until the indexing has completed.
To minimize TSM downtime after upgrade, the
can be created prior to performing the upgrade using the
index_tierfiles.pl
Appliances page on CSWeb. The script can be run while TSM is running,
although it may impact the performance of other operations while the
index is being added to the database.
Caution: The following script should only be executed against
StorNext release as indicated in the previous section.
To manually add the index:
1 Download the
index_tierfiles.pl
2 Login to the primary MDC, and access the command line of the
system.
