Using the SCR Tool
The SCR Tool downloads patch content files from the Content Download Network (CDN) (managed by
Akamai, the hosted content service provider), obtains any additional patches from the Red Hat and Solaris
vendor sites, and saves those patches in the path(s) that you define.
The SCR Tool performs delta downloads. After the first download, successive downloads will retrieve only
the differences in patch content since the last download. When the files are downloaded, the patch source,
CDN, Vendor, and other information is recorded in the log files.
I
The patch signature (.pls) files are stored in the platform sub-directories of <scr_root>, and
MPORTANT
are used to confirm whether the patches are available. Make sure that you do not delete these files.
Download the Patch Content
To download patch content onto the Red Hat host machine, follow these steps:
1. Run the updated replication scripts using crontab to specify the shell commands to be executed on a
particular schedule.
2. If you want to interactively track the progress of the download, open a terminal session and execute
the following commands:
date; df -kh | grep /home; du -kh | grep payload/
3. When the patch download process is complete, use VCM Patching to patch the UNIX machines.
How to Schedule Downloads
The SCR Tool does not provide embedded scheduling. You can automate running the scripts using OS
schedulers, such as cron or at.
N
If multiple platforms connect to the same repository, schedule the execution of the replication
OTE
scripts for each platform separately.
