The <SMALL>SCRAM</SMALL> database file is called <TT>project.lookup</TT> and
|
| 76 |
contains lookup tables for the various projects that may be
|
| 77 |
installed on your system. The database is read
|
| 78 |
during a <TT>scram list</TT> command. Usually, the database file
|
| 79 |
lives in the <TT>scramdb</TT> directory of
|
| 80 |
your <SMALL>SCRAM</SMALL> installation area and is accessible to all <SMALL>SCRAM</SMALL>
|
| 81 |
versions. The database directory is created automatically at
|
| 82 |
installation time. The default location can be overridden with the
|
| 83 |
environment variable <TT>SCRAM_LOOKUPDB</TT>.

A project can be installed into the database using the command
|
| 91 |
|
| 92 |
<P>
|
| 93 |
<TT>scram install</TT>
|
| 94 |
|
| 95 |
[<I>project_name</I>] [<I>project_version</I>]
|
| 96 |
|
| 97 |
<P>
|
| 98 |
This command is usually executed in the project area of the
|
| 99 |
project (and version) to be installed. If the project name and
|
| 100 |
version are given then these will be used in the database in place of
|
| 101 |
the project defaults.

A project can be removed from the database using the command
|
| 109 |
|
| 110 |
<P>
|
| 111 |
<TT>scram remove</TT>
|
| 112 |
|

<TT>project_name</TT> <TT>project_version</TT>
|
| 114 |
|
| 115 |
<P>
|
| 116 |
This command can be executed anywhere but will only work if the
|
| 117 |
user has write permissions on the <TT>project.lookup</TT> file.

Other databases can be linked to the local installation database
|
| 126 |
using the command
|
| 127 |
|
| 128 |
<P>
|
| 129 |
<TT>scram db link</TT>
|
| 130 |
|
| 131 |
<<I>otherdb</I>>
|
| 132 |
|
| 133 |
<P>
|
| 134 |
This is often useful if a local copy of a project is maintained
|
| 135 |
for development but a released project is required for access to
|
| 136 |
configuration information and libraries. All projects listed in the
|
| 137 |
linked database will be shown by <TT>scram list</TT>. Note that
|
| 138 |
<TT>scram install</TT> and <TT>scram remove</TT> commands will not
|
| 139 |
affect databases that are linked in.
