Create IBM DB2 databases manually
Create IBM DB2 databases with SQL scripts instead of using the IBM Connections database wizard.
Before starting
Use this procedure if you do not want to use the database wizard to create your databases.The SQL scripts are located in a compressed file called connections.sql.zip|tar, located in the Lotus_Connections_install/LotusConnections/connections.sql directory of the IBM Connections set-up directory or installation media. Extract this file before proceeding. When extracted, the SQL scripts are located in the LotusConnections/connections.sql/<application_subdirectory> directory of the IBM Connections set-up directory or installation media, where <application_subdirectory> is the directory that contains the SQL scripts for each application. If you are using AIX , see the note in the Preparing the database wizard topic about decompressing TAR files.
Note:
- If you are using Linuxâ„¢ on IBM System z with the DASD driver, the SQL scripts are located in the Lotus_Connections_Install_s390/LotusConnections/connections.s390.sql directory.
- If you are using Linux on IBM System z with the SCSI driver, back up the connections.s390.sql directory and rename the connections.sql directory to connections.s390.sql.
If the database server and IBM Connections are installed on different systems, copy the SQL scripts to the system that hosts the database server.
(AIX only) Configure the AIX system that hosts the DB2 databases to use the enhanced journaled file system (JFS2), which supports file sizes larger than 2 GB. To enable large files in the JFS system, perform the following steps:
- In the SMIT tool, select System Storage Management File System>Add/Change/Show/Delete File Systems
- Select the file system type you want to use and specify other characteristics as wanted. If you use a Journaled File System, set the Large File Enabled setting to true.
See the AIX documentation for more options.
Notes:
When you are creating a database either with the database wizard or SQL scripts, log into the system where the database is hosted with the database administrator account. The default values for DB2 are db2admin on Microsoftâ„¢ Windowsâ„¢ and db2inst1 on Linux and AIX. For Oracle, the default value is oracle on AIX or Linux, and system administrator on Windows . For SQL Server, the default value is the system administrator
DB2 only. If you are hosting IBM DB2 on a single 32-bit system, you should create multiple DB2 instances. A single DB2 instance on a 32-bit system can manage a maximum of 2 GB of data in memory and this can become a constraint when you install multiple IBM Connections applications. At a minimum, create two DB2 instances when you are installing all the applications, but also consider creating separate instances for the Activities and Communities databases because they are usually the most memory-intensive databases. Ideally, you would install one DB2 instance per IBM Connections application. If you are hosting DB2 on a 64-bit system, you do not need to create multiple instances, provided the system has sufficient RAM.
About this task
You must perform this task for each IBM Connections application that you are installing.Note: To capture the output of each command to a log file, append the following parameter to each command: >> /<file_path>/db_<application>.log
where <file_path> is the full path to the log file and <application> is the name of the log file. For example:
db2 -tvf createDb.sql >> /home/db2inst1/db_activities.log
Ensure that you have write permissions for the directories and log files.
To create the application databases...
Procedure
- Optional:Â (Only required if the database server and IBM Connections are installed on different systems.) Copy the IBM Connections SQL scripts to the DB2 database system. Authorize a user ID that can create the databases.
- Log in to the DB2 database system with the user ID of the owner of the database instance. The user ID must have privileges to create a database, a tablespace, tables, and indexes.
Notes:
- If you created multiple database instances, specify the user ID for the first instance.
- The default administrative ID for Microsoft Windows is db2admin.
- Start the DB2 command line processor in command mode and enter the following command:
db2start
- For Home page and Profiles, change to the directory where the SQL scripts for each application are stored, and then enter the following command to run the script:
db2 -tvf createDb.sql
- For Home page, run the following script:
db2 -tvf initData.sql
- For Activities, Communities, Blogs, Bookmarks, Files, Forums, and Wikis, change to the directory where the SQL scripts for each application are stored, and then enter the following command to run the script:
db2 -td@ -vf createDb.sql
Note: The Bookmarks SQL scripts are stored in the dogear directory.
- Run the following command to grant access privileges to the lcuser account for the Home page and Profiles databases:
db2 -tvf <application_subdirectory>/appGrants.sql
- Run the following command to grant access privileges to the lcuser account for the Activities, Communities, Blogs, Bookmarks, Files, Forums, and Wikis databases:
db2 -td@ -vf <application_subdirectory>/appGrants.sql
- Run the following commands to generate statistics for the Home page database:
db2 -tvf <application_subdirectory>/reorg.sql
db2 -tvf <application_subdirectory>/updateStats.sql
- Close the DB2 command line processor.
- Optional:Â When you install IBM Connections, the JDBC configuration page of the installation wizard asks you to provide a user ID and password for the Application User. The user ID that you specify on that page must have read and write access to the database. You can provide the user ID of an administrative user or you can create a dedicated user ID with fewer privileges. See the Create a dedicated DB2 user topic for more information.
What to do next
(DB2 for Linux on System z only.) To improve database performance, enable the NO FILE SYSTEM CACHING option. For more information, see the Enable NO FILE SYSTEM CACHING for DB2 on System z topic.
