You can use the Catalog tab of the MediaAgent Properties dialog box to view and modify index file parameters and retention criteria.
Index Directory
Enable this Access Path
Select this check box to make the path in index directory active.
Index Directory
The directory where index data is stored.
You can change this directory. If it does not already exist, the MediaAgent software creates it in the default location, software_installation_directory/IndexCache.
When you change this setting, the MediaAgent copies the existing cache contents to the newly specified index cache directory, and directs all new cache entries to the new directory. Because the Windows MediaAgent copies the existing cache contents, you can manually delete the original directory to free up disk space.
Notes
-
Use a file system dedicated to index data, so that non-index data does not consume index capacity.
-
Estimate your index cache space requirements with a sufficient margin of safety by allocating more space rather than less. If you are maintaining backward-compatible content indexes generated by a previous software version, the index cache directory may require more space.
-
For best performance, locate the index cache directory on a solid state drive (SSD).
-
Do not locate the index cache directory on a compressed drive.
-
For Windows, do not place the index cache directory directly under the software_installation_directory.
-
For UNIX, do not specify root as the index directory.
-
The index cache directory path must meet the following requirements:
-
It may not exceed 75 characters.
-
It may not contain the "!" character.
-
It may not contain Unicode characters.
-
-
Do not host the index cache directory on your CommServe computer, unless you only have one MediaAgent and that MediaAgent is located on that computer.
Browse
Click to locate the index cache directory in a Windows tree, and then set it.
Offline Reason
If the index cache directory is offline, this field displays the reason.
Index Retention
Retain index for n days
Note
This option does not apply to the latest version of indexing. For information about index retention in the latest version of indexing, see Index Cleanup and Compaction Operations.
When an index becomes older than this parameter, the system runs a cleanup job that automatically deletes the index and log files within 24 hours.
Generate alerts when free space falls below n GB
If the amount of free space in the index cache falls below this parameter (default = 50GB), the system sends alerts to the administrator email account. For more information, see the predefined alert "Disk space low on MediaAgent" in Alerts and Notifications - Predefined Alerts.
Note
If you want to set this parameter to 10 GB or less, you must use the Change Index Cache Configuration workflow. You cannot set this parameter to 10 GB or less in the MediaAgent Properties dialog box.
Index Directory Space
These fields display the current state of index cache directory space usage. For more information about index space requirements, see Planning.
Total Size
The total volume size (in MB or GB) that the index cache directory resides on.
Index
Index cache directory disk space (in MB or GB) currently used by index files. The number in parentheses shows the usage as a percentage of the Total Size disk space. Note that when index files are changed, added, or deleted, it make take up to 30 minutes for the Index value to update.
Other Data
Index cache directory disk space (in MB or GB) currently used by data other than index files. The number in parentheses shows the usage as a percentage of the Total Size disk space.
Free Space
Free disk space (in MB or GB) available to the index cache directory. The number in parentheses shows the free disk space as a percentage of the Total Size disk space.
