Chapter 5 Staging 139
Specifying the Number of Stage Requests
The maxactive directive enables you to specify the number of stage requests that
can be active at any one time.
This directive has the following format:
By default, number is 4000. The minimum number allowed is 1. The maximum
allowed is 500,000.
For example, the following directive line specifies that no more than 500 stage
requests can be in the queue simultaneously:
Example stager.cmd File
CODE EXAMPLE 5-2 shows an example stager.cmd file.
Specifying Stage Attributes for All Files in an
Archive Set
Most directives in the archiver.cmd file affect archiving, but the archive set
assignment directive allows you to specify stage attributes that apply to all files in
an archive set.
maxactive=number
maxactive=500
CODE EXAMPLE 5-2 Example stager.cmd File
# This is stager.cmd file /etc/opt/SUNWsamfs/stager.cmd
drives=dog 1
bufsize=od 8 lock
logfile=/var/adm/stage.log
maxactive=500
