SymptomsNote: The article applies only to OpenSUSE 12.1.
It is taking up to 20-30 minutes to install an application from the Application vault.
CauseThe issue is caused by the MyODBC-unixODBC package bug.
Parallels Plesk Panel uses the ODBC driver to communicate with the Application vault ("apsc") database. Due to this bug, delays occur after each query.
The bug is going to be fixed in a future release of the MyODBC-unixODBC package.

2. Install the downloaded package using this command:
# rpm -i --force mysql-connector-odbc-5.1.11-1.*.rpm
