config_ccase

ClearCase and ClearCase LT configuration

APPLICABILITY

SYNOPSIS

Most ClearCase configuration options can be set using a cleartool command or a ClearCase GUI. Only a few require you to edit a text file (on UNIX) or a Windows registry key as described here.

DESCRIPTION-UNIX SYSTEM FILES

Files in /var/adm/atria

Anyone can read the information in this directory, but only the root user can modify it.

license.db

(License server host only) The license database file, which defines a set of ClearCase licenses. See the Administrator's Guide.

Files in /var/adm/atria/config

Anyone can read and write information in this directory to configure the local host.

alternate_hostnames

If a host has two or more network interfaces (two or more separate lines in the /etc/hosts file or the hosts NIS map), you must create a file with this name on that host to record its multiple entries. For example, suppose that the /etc/hosts file includes these entries:

159.0.10.16 widget sun-005 wid
159.0.16.103 widget-gtwy sun-105

In this case, the alternate_hostnames file should contain:

widget
widget-gtwy

Note that only the first hostname in each hosts entry need be included in the file. The file must list each alternative host name of a separate line. There is no commenting facility; all lines are significant. If a host does not have multiple network interfaces, this file should not exist at all.

automount_prefix

By default, automount(1M) mounts directories under /tmp_mnt. If another location is used for a host's automatic mounts (for example, you use automount -M, or you use an alternative auto-mount program), you must specify it in file /var/adm/atria/automount_prefix. For example, if your automatic mounts take place within directory /autom, create an automount_prefix file containing this line:

/autom

bldserver.control

Controls the way in which a host is used during parallel builds. See Building Software.

license_host

(Required for each ClearCase host) Contains the name of the host that acts as the ClearCase license server host for the local host.

snapshot.conf

Configuration information for semi-live VOB backup. See the vob_snapshot reference page for more information.

admin.conf

Controls whether this host's Clearcase properties can be changed by a user logged into a remote host.

db.conf

Configuration information for the file, vista.tjf, which is a journal of VOB updates. This file can grow large, especially as a result of such operations as rmver, rmview, rmtype, and scrubber. To limit the size of vista.tjf, create the file db.conf (in /var/adm/atria/config) and add the line

-journal_file_limit bytes

where bytes may not be less than 5000000. Setting this value too low may degrade performance.

Files in /var/adm/atria/rgy

Anyone can read these files but only the root user can modify them to configure the local host.

rgy_hosts.conf

Specifies this host's registry server and backup registry server hosts.

rgy_region.conf

Specifies this host's registry region.

DESCRIPTION-WINDOWS REGISTRY KEYS AND FILES

Values in Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Atria\ClearCase\CurrentVersion

If necessary, you may modify these values directly with a Windows Registry Editor.

Files in ccase-home-dir\var\config

Anyone can read or write to this directory.
