Transaction Tracking System (Tts); Setting The Cache Buffers - Novell NETWARE 6-DOCUMENTATION Manual

Transaction Tracking System (TTS)

Setting the Cache Buffers

Upgrading NSS Volumes
To upgrade NSS volumes, enter one of the following commands at the
NetWare 6 server console:
NSS /ZLSSVOLUMEUPGRADE=ALL
NSS /ZLSSVOLUMEUPGRADE=volumename
Transaction Tracking protects database applications by backing out
transactions that are incomplete due to a system failure. TTS can be available
on either all traditional or all NSS logical volumes. It cannot be available on
all volumes if you use both types of volumes. If your system uses both
traditional and logical volumes, by default it can only work on traditional
volumes. If you want to use it on logical volumes on a system that has both,
you must enter DISABLE TTS on the AUTOEXEC.NCF then enable the
feature on each logical volume you want it on. Unlike traditional volumes,
TTS does not apply to logical volumes by default. To enable it on logical
volumes, enter the following command at the server console:
nss/transaction=<volname>.
A cache buffer is a block (4 Kb) of NetWare server memory (RAM) that
temporarily stores data. When you install NSS, it consumes 60 percent of the
the cache buffers by default.
The following are options for changing the cache buffers:
You can set a maximum of 1048576 cache buffers.
You can set the buffers in percentages rather than integers.
Use the following commands at the server console to set your cache buffers or
tune your cache parameters. You can set or tune cache buffers at anytime.
