Cygwin command line installation

Have you ever wished you could install Cygwin programs via the command line? Well you can. Just use this shellscript that Stephen Jungels wrote. Just download it into your cygwin /usr/bin directory and modify if necessary. View apt-cyg

  • First ssh to the cygwin box.
  • Next download the needed packages for apt-cyg
  • ./setup.exe -q -P  wget,tar,qawk,bzip2,subversion,vim
  • Finally, download the apt-cyg script from Stephen’s repository.
  • $ svn –force export http://apt-cyg.googlecode.com/svn/trunk/ /bin/
  • $ chmod +x /bin/apt-cyg

Now that you have all the tools, just run the “apt-cyg” command to find and install anything from the cygwin repositories.

“apt-cyg install <package names>” to install packages
“apt-cyg remove <package names>” to remove packages
“apt-cyg update” to update setup.ini
“apt-cyg show” to show installed packages
“apt-cyg find <pattern(s)>” to find packages matching patterns
“apt-cyg describe <pattern(s)>” to describe packages matching patterns
“apt-cyg packageof <commands or files>” to locate parent packages

Oracle Database 11g Express Edition Configuration
————————————————-
This will configure on-boot properties of Oracle Database 11g Express
Edition. The following questions will determine whether the database should
be starting upon system boot, the ports it will use, and the passwords that
will be used for database accounts. Pressto accept the defaults.
Ctrl-C will abort.
Specify the HTTP port that will be used for Oracle Application Express [8080]:
Specify a port that will be used for the database listener [1521]:
Specify a password to be used for database accounts. Note that the same
password will be used for SYS and SYSTEM. Oracle recommends the use of
different passwords for each database account. This can be done after
initial configuration:
Confirm the password:

EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);
exit
–
reboot
access apex remotely now at http://hostname:8080/apex/apex_admin
user = admin
password = whateveruenteredatinstall

this forces you to change password

Default “workspace” is INTERNAL
