When Entire Net-Work is installed, the log file (WCPvnnnInst.log, where nnn is the version, release, and maintenance level, is written, and another file, WCPvnnnInst.sh, which contains the batch installation settings of this particular installation, is written to $SAG/wcp/vnnn/INSTALL. This file can then subsequently be executed as a shell script. An example is shown elsewhere in this document.
Note:
WCB (including Software AG's System Management Hub) must already be
installed before you can install Entire Net-Work in batch mode.
If you install the product in character mode, the option
-batch can be used to execute the installation program without
further user interaction. If user input is required, the default values are
used; if these values are not appropriate, the correct values have to be set
using the corresponding options in the command line. The available command line
options can be displayed by calling the installation program with the
-help option.
 |
Warning: Since the value of $SAG cannot be set using an option, it must already have the correct value in the calling shell. |
All prerequisites and parameters are checked for correctness: missing or invalid values will cause the batch installation to terminate.
This document covers the following topics:
Installation programs that require post-installation actions executed as a superuser usually have the following three options:
| Variable/Flag Name | Type | Value | Explanation |
|---|---|---|---|
| -user | string | ( ) | User account of SAG user |
| -password | string | ( ) | Root password (usage not recommended) |
| -authcmd | choice | (su sudo "") | Command used for authentication |
It is possible to specify the superuser password (or the user's password in connection with -authcmd sudo), as the value of the -password option, but this should not be done, because the password would appear as readable plain text on the screen or, even worse, be stored in the calling shell script, as shown below:
# Unsafe method sh /cdrom/setupux -batch -password secret
Instead, we recommend that you start the installation program using su or sudo, specifying the name of the SAG user (i.e. its own account) as the value of the -user option as shown below:
# Recommended method su root -c "sh /cdrom/setup.ux -batch -user sag"
Here is an example of a generated batch script for Entire Net-Work that was created during a custom installation. The user is "sag", the sudo command was used, and a password was supplied.
