Use the preferred method: MS SQL Server and MS JDBC Driver (recommended) |
About Microsoft SQL Server
Microsoft SQL Server (MSSQL) is a commercial database product available from Microsoft

1. Adopters should enable the ALLOW_SNAPSHOT_ISOLATION and READ_COMMITTED_SNAPSHOT options in the portal database. Without these options, MSSQL Server will encounter deadlocks in the portlet preferences subsystem under load. You can read more about these setting here. Perform the following commands to enable these settings:
2. MSSQL Server 2005 or later: uPortal 4 starts up correctly, but the channels contain no content. SQLServer2005Dialect writes 'varchar(MAX)' where it should be 'text'. Changing the column definitions below to be 'text' fixes the problem: UP_PORTLET_PREF(PREF_NAME) UP_PORTLET_PREF_VALUES(PREF_VALUE) UP_RAW_EVENTS(EVENT_DATA) 3. MS SQL Server 2005 or later: disable or delete the single uniqueness index on table UP_DLM_EVALUATOR. This index should ensure that if a fragment name is provided (is not null) then it must be unique. Unfortunately, MS SQL server is unable to provide such indexes since uniqueness check of 'null =? null' returns true when building index keys. This is not the case for other DBMS vendors (i.e. postgres). If you're using MS SQL 2008 or later, you can (and should) create a new filtered index to replace the deleted index in order to maintain data integrity. Here's the required SQL query:
Workaround above was submitted by Arvīds Grabovskis who deployed uPortal 4.0.3 at Riga Technical University, you can read his blog entry on the topic here. |
Step 1
...
: Obtaining
...
the Driver
| Note |
|---|
If using uPortal 4.0.9+, it is best to use the MS SQL Server and MS JDBC Driver (recommended) (click on link to view the instructions) |
Since the jTDS JDBC driver for MSSQL is not available in the central Maven repository, it must be placed into the local repository of each machine on which you wish to build uPortal.
...
The groupId, artifactId and version specified in this command are up to you, but they should match the JAR vendor, name and version to avoid confusion down the road.
Step 2
...
: Add the Dependency
From the uPortal source directory, open the uPortal-4.x.x/pom.xml file, there is a section about 110 lines down that reads:
...
See Issues section about possible issues using this driver.
Step 3
...
: Configure the Database Filter
1. NEW: In the filters folder, locate the default local.properties file under uPortal-4.0x.x/filters/local.properties and configure the Database Connection Settings
| Code Block | ||
|---|---|---|
| ||
# HSQL Configuration environment.build.hsql.port=8887 # Database Connection Settings (Uncomment the Maven Filters section in rdbm.properties) environment.build.hibernate.connection.driver_class=net.sourceforge.jtds.jdbc.Driver environment.build.hibernate.connection.url=jdbc:jtds:sqlserver://my.school.edu:1433/uPortal3db environment.build.hibernate.connection.username=sa environment.build.hibernate.connection.password= environment.build.hibernate.dialect=org.hibernate.dialect.SQLServerDialect |
Step 4
...
: Test the Configuration
Running the dbtest ant target will tell you if you have configured the database connection properly.
| Code Block |
|---|
ant dbtest |
...
Step 5: Build and Deploy
Following a successful test, you can execute
...
| Code Block |
|---|
ant initportal
|
...
the command below to build the database tables and copy files to your servlet container.
| Warning | ||
|---|---|---|
| ||
Note: Executing the command "ant clean initportal" will drop and recreate the database tables and all existing data will be lost. This will result in a clean uPortal database structure. If you want to keep the contents of your existing database, use "ant clean deploy-war" |
| Code Block |
|---|
ant clean initportal |
Step 6: Restart Tomcat
