Overview and Setup for SirFile

●
“Running SirFile under BATCH204” on page 35 , for a method that can be useful for
calculating CFULLP
The SirFile refresh process is always in “learn” mode. Any file that is open when a
SirFile refresh is run is automatically added to the SirFile database, using the default
thresholds for comparison.
2.1 Files available for SirFile Monitoring
For SirFile to collect information on a file, it must be open in the region by some user or
subsystem. To guarantee that certain files are included in the initial load, those files can
be opened manually before initiating the refresh process. Because storing user-entered
passwords would violate most sites' security, SirFile uses a variety of methods to make
files available to itself without needing to store passwords.
1. If a file is open in the region, or SirFile manages to open the file with default
privileges, the file is added to the database and no user intervention is required.
2. The first time SirFile collects data for a file it adds the file to its Application
Subsystem definition (with low privileges in the “USER” SCLASS and high privileges
in the “ADMIN” SCLASS). Thereafter, no password is required for SirFile to open
the file. Files that are prefixed “CCA” are exempted from this operation, as these
files cause problems in SUBSYSMGMT.
3. If SirFile has a file in its database that requires a password, and a non-periodic
refresh is running (other than SIRFILE BATCH), you are prompted for the password.
4. If SIRFILE BATCH or a periodic refresh is running, SirFile skips any file it cannot
open.
2.2 File enqueuing
Besides its APSY procedure file and the UL/SPF file SIRLOCAL, SirFile requires update
access to CCASYS. All other files, even if they are defined to SirFile as optional APSY
files, are closed and freed from the subsystem at the end of each user's SirFile session.
This is done to reduce enqueuing problems.
