Configuring ON-Bar for optional TSM features

You can configure ON-Bar to enable or disable optional features in HCL® Tivoli® Storage Manager (TSM).

Apply all patches and updates to TSM before you use the following TSM features.

Deduplication
Deduplication eliminates redundant data in backups. To enable the database server to support deduplication, set the IFX_BAR_USE_DEDUP environment variable in the HCL OneDB™ environment and restart the database server. Update the TSM client systems option file.
Large transfer buffer size
The default transfer buffer size is 64 KB. Set the BAR_XFER_BUF_SIZE configuration parameter to specify a transfer buffer of up to 65 MB.
To limit the transfer buffer size to 64 KB regardless of the value of the BAR_XFER_BUF_SIZE configuration parameter, set the IFX_NO_LONG_BUFFERS environment variable to 1.
Replicate, import, and export backup objects
Replicating, importing, or exporting backup objects between TSM servers requires unique IDs for backup objects. ON-Bar automatically stores IDs in the metadata of backup objects that are unique for all TSM server with version 11.70.xC8 or later with version 12.10.xC2 or later.
To disable the ability to restore backup objects that are moved between TSM servers, set the IFX_TSM_OBJINFO_OFF environment variable to 1.
