Manual InstallationThis is the baseline deployment recommendation we have for the OPL product when Juju is not used. At a minimum, we have two machines:. database server, running Ubuntu 18.04 LTS ('bionic'), with PostgreSQL 10. application server, running the same version of Ubuntu as the Database server, hosting the Landscape servicesThis is a long document.

In Java default traces, there are errors similar to the ones below. Unable to find associated SLD element for specified class (source element: SAPXIIntegrationDirectory, CreationClassName, SAPXIIntegrationDirectory, string, Name, directory.SID.hostname, string, ta. Joel16 released this on Sep 30, 2019 4 commits to master since this release. This is a hot fix for v2.10 which resulted in issues with file deleting, copy/move etc. This also addresses the system version 9.00 fix. Fix FS logic which resulted in files not being deleted, copied or moved. Display a message when deleting a file until it has.

Don't be intimidated. If you want a quick installation that just works, but doesn't scale to a large number of machines, then install the landscape-server-quickstart package.

Preparing for the installationWhat you will need:. Ubuntu 18.04 LTS ('bionic') server install media.

Landscape On-Premises license file. If you don't have one, a free demo license with a small number of seats will be used instead. Server X509 certificate and key, signed by a publicly known Certificate Authority, and issued for the FQDN hostname of the application server. Custom CAs can be used, but this is not documented here as it's considered an advanced topic. Administrators deploying custom CAs most likely know what needs to be done. In any case, this quick how-to may help.

You MUST use the same version of Ubuntu on both the Application server and the Database server.Installing the Database ServerAfter having installed the basic server profile of Ubuntu Server, we need to install the PostgreSQL database and configure it for use by Landscape. Please follow these steps: Install PostgreSQL and required librariesIn the database server, run this command to install the database software. Warning: Do not use an @ symbol in the password.If this database is to be shared with other services, it is recommended that another cluster is created instead for those services (or for Landscape). Please refer to the PostgreSQL documentation in that case.

Configure PostgreSQLWe now need to allow the application server to access this database server. Landscape uses several users for this access, so we need to allow them all.

Edit the /etc/postgresql/10/main/pghba.conf file and add the following to the end. Host all landscape,landscapemaintenance,landscapesuperuser md5Replace with the IP address of the application server, followed by /32. Alternatively, you can specify the network address using the CIDR notation. Some examples of valid values:. 192.168.122.199/32: the IP address of the APP server. 192.168.122.0/24: a network addressNow come changes to the main PostgreSQL configuration file.

Edit /etc/postgresql/10/main/postgresql.conf and:. find the listenaddresses parameter, which is probably commented, and change it to. Sudo systemctl restart postgresqlTune PostgreSQLIt is strongly recommended to fine tune this PostgreSQL installation according to the hardware of the server. Keeping the default settings (especially of maxconnections) is known to be problematic. Please see the following resources for more information:.If this tuning changed the value of maxconnections, make sure you also change maxpreparedtransactions to the same value!

Installing the application serverThe application server will host the following Landscape services:. application server. message server.

ping server. job handler. async-frontend. combo loader. api server.

package upload service. package searchAdditionally, other services needed by Landscape will also be running on this machine, such as:. apache. rabbitmq-serverLet's begin. Adding the Landscape package archive and installing the packageLandscape is distributed in a public PPA. You can add it to the system with these commands.

Sudo systemctl restart rabbitmq-serverConfigure database and broker accessWe now need to make some configuration changes to the /etc/landscape/service.conf file to tell Landscape how to use some other services:Please make the following changes:section stores:. host: the IP or hostname of the database server. Note: If more performance and availability are needed out of OPL, it's possible to spread out the services amongst several machines. In that case, for example, one could run message servers in one machine, application servers in another one, etc.The message, application and ping services can be configured to run multiple instances. If your hardware has several cores and enough memory (4Gb or more), running two or more of each will improve performance. To run multiple instances of a service, just set the value in the respective RUN line to the number of instances.

For example, if you want to run two message servers, just set. Note: In order to take advantage of this multiple-instances setting, you need to configure some sort of load balancer or proxy.

See the README.multiple-services file in the landscape-server package documentation directory for an example using Apache's proxyloadbalancer module.In that same file, the UPGRADESCHEMA option needs to be reviewed. If set to yes, whenever the package landscape-server is updated it will attempt to update the database schema too. It is a very convenient setting, but please think about the following before enabling it:. schema updates can take several minutes. if the package is updated while the database is offline, or unreachable, the update will fail. you should have a backup of the database before updating the packageWithout this setting enabled, a package update might result in services that won't start anymore because of a needed schema change.

In that case:. stop all the Landscape services.

backup your database. Update the schema on the application server. Sudo setup-landscape-server. start all Landscape services againWebserver configurationLandscape uses Apache to, among other things, redirect requests to each service and provide SSL support. The usual way to do this in Ubuntu is to create a Virtual Host for Landscape.Below is a suggested configuration file that does just that. Install it as /etc/apache2/sites-available/landscape.conf and change the following values:.

@hostname@: the FQDN of the hostname the clients (browser and machines) will use to connect to OPL. This is what will be in the URL, and it needs to be resolvable via DNS. For example, lds.example.com. @certfile@: the full filesystem path to where the SSL certificate for this server is installed. For example, /etc/ssl/certs/landscapeserver.pem. @keyfile@: the full filesystem path to where the corresponding private key of that certificate is installed. For example, /etc/ssl/private/landscapeserver.keyIf you are using a custom certificate authority for your SSL certificate, then you MUST put the CA public certificate in the file /etc/ssl/certs/landscapeserverca.crt and uncomment the SSLCertificateChainFile /etc/ssl/certs/landscapeserverca.crt line.Make sure the user apache runs as can read those files!

Also, make sure the private key can only be read by root and that same apache user.

Definition

Specifies how pages of content are oriented on print media.

Inheritance

Fields

Landscape	1	Content of the imageable area is rotated on the page 90 degrees counterclockwise from standard (portrait) orientation.
Portrait	2	Standard orientation.
ReverseLandscape	3	Content of the imageable area is rotated on the page 90 degrees clockwise from standard (portrait) orientation.
ReversePortrait	4	Content of the imageable area is upside down relative to standard (portrait) orientation.
Unknown	0	The feature (whose options are represented by this enumeration) is set to an option not defined in the Print Schema.

Examples

The following example shows how to use this enumeration to set PrintTicket values. Pinnacle studio 24.

Considering the wide-open nature of its architecture, the PSP remains in popular demand amongst retro gamers. If you unlock the system with the simple prefab boot software located on an SD card, you’ll get an array of retro emulation including the ability to use any PSP ISO file of your choice. There is also a possibility to run PSP ROMS on. Psp iso folder download. To browse PSP ISOs, scroll up and choose a letter or select Browse by Genre. If you're feeling adventurous, try the advanced rom browser. Downloads Links for PSP ISOs. Sony PlayStation Portable game roms to play on your PSP Console or any device with PPSSPP emulator.

Remarks

Use the values of this type primarily for these purposes:

• As members of the PageOrientationCapability collection, which is a property of PrintCapabilities, these values indicate the orientation types that a printer supports.

• As the value of the PageOrientation property of a PrintTicket, the value directs the printer to use a particular orientation.

The Unknown value is never used in properties of PrintCapabilities objects.

You should never set a PrintTicket property to Unknown. If some other PrintTicket producing application has created a PrintTicket document that sets the orientation feature to an unrecognized option (that is, an option that is not defined in the Print Schema), then a PrintTicket object in your application that is constructed with that document will have Unknown as the value of the PageOrientation property.

Although the PrintTicket and PrintCapabilities classes cannot be inherited, you can extend the Print Schema to recognize print device features that are not accounted for in the PrintTicket or PrintCapabilities classes. For more information see How to: Extend the Print Schema and Create New Print System Classes.
