# Install Persistence Layer

## Install Persistence Layer for GemStone/S

**Create the folder structure to store forms attachments**\
By default the attachment path is `/opt/orbeon-files/` in this directory execute:

```
cd /opt/
sudo mkdir orbeon-files
sudo chown gemstone orbeon-files/
cd orbeon-files
mkdir temp
mkdir drafts
mkdir instances
mkdir definitions
cd definitions/
mkdir saved
mkdir published
```

To change the default attachment path evaluate (and create the folder structure):

```
OrbeonApiConfiguration default baseAttachmentPath: 'myPathHere'
```

The whole project will be installed at:\
\&#xNAN;**/home/{username}/GsDevKit\_home/shared/repos/OrbeonPersistenceLayer**

**Installation Script**\
The following scripts will install **OrbeonPersistenceLayer** on **GemStone/S** named "**devKit\_351**" and start the Web Server. Update this script with the name used in your **GemStone/S** installation:\
`$ cd $GS_HOME/shared/repos/OrbeonPersistenceLayer/scripts`\
`$ sh install-all.sh devKit_351`\
`$ sh register-application.sh devKit_351`\
`$ sh start-all.sh devKit_351`

**Orbeon Properties-local.xml Configuration**\
In **Orbeon** in ***properties-local.xml*** file add the following options:\
(change the ip address of \[oxf.fr.persistence.gemstone.uri] to suit your needs)

```
<property as="xs:string" name="oxf.fr.persistence.provider.*.*.*" value="gemstone"/>
<property as="xs:anyURI" name="oxf.fr.persistence.gemstone.uri" value="http://192.168.29.133:8888/orbeon-gemstone-api"/>
<property as="xs:boolean" name="oxf.fr.persistence.gemstone.versioning" value="true"/>
<property as="xs:boolean" name="oxf.fr.persistence.gemstone.permissions" value="true"/>
<property as="xs:boolean" name="oxf.fr.persistence.gemstone.autosave" value="true"/>
<property as="xs:string" name="oxf.fr.persistence.gemstone.data-format-version" value="2019.1.0"/>
```

**Note**: only **2019.1.0 Format** is supported. Forms formats **4.0.0** and **4.8.0** will **likely** work without problems but **2019.1.0** is the official supported format.

If you are going to use **BPM Flow + Orbeon**  then also set:\
`<property as="xs:boolean" name="oxf.fr.persistence.gemstone.lease" value="false"/>`

If you are going to use only **Orbeon Persistence Layer** then set:\
`<property as="xs:boolean" name="oxf.fr.persistence.gemstone.lease" value="true"/>`

If you have any question about GemStone/S:\
