Database Scripts for creating Portal database on DB2

For migrating WebSphere Portal database from Derby (default portal database) to other database like DB2 you need to first create the databases in DB2. Portal uses following 6 databases to store different kind of 
information so the first step is to create the following databases in DB2.
1. Release 
2. Community 
3. Customization 
4. JCR 
5. Feedback 
6. Likeminds 

Following scripts create all the databases required by the Portal on DB2. For executing these scripts open DB2 Command window and copy and paste each of the commands mentioned in the script one by one or you can also copy and paste them as a single script.If everything goes well, you will saw a successful message at the end.

JCR database update script

You need to perform following additional steps on the JCR DB to match it with the Portal's requirements. replace & with the one you used to create the database. 

db2 "CONNECT TO jcrdb USER userid USING pasword" 
db2 "CREATE BUFFERPOOL ICMLSFREQBP4 SIZE 1000 PAGESIZE 4 K" 
db2 "CREATE BUFFERPOOL ICMLSVOLATILEBP4 SIZE 8000 PAGESIZE 4 K" 
db2 "CREATE BUFFERPOOL ICMLSMAINBP32 SIZE 8000 PAGESIZE 32 K" 
db2 "CREATE BUFFERPOOL CMBMAIN4 SIZE 1000 PAGESIZE 4 K" 
db2 "CREATE REGULAR TABLESPACE ICMLFQ32 PAGESIZE 32 K MANAGED BY SYSTEM USING ('ICMLFQ32') BUFFERPOOL ICMLSMAINBP32" 
db2 "CREATE REGULAR TABLESPACE ICMLNF32 PAGESIZE 32 K MANAGED BY SYSTEM USING ('ICMLNF32') BUFFERPOOL ICMLSMAINBP32" 
db2 "CREATE REGULAR TABLESPACE ICMVFQ04 PAGESIZE 4 K MANAGED BY SYSTEM USING ('ICMVFQ04') BUFFERPOOL ICMLSVOLATILEBP4" 
db2 "CREATE REGULAR TABLESPACE ICMSFQ04 PAGESIZE 4 K MANAGED BY SYSTEM USING ('ICMSFQ04') BUFFERPOOL ICMLSFREQBP4" 
db2 "CREATE REGULAR TABLESPACE CMBINV04 PAGESIZE 4 K MANAGED BY SYSTEM USING ('CMBINV04') BUFFERPOOL CMBMAIN4" 
db2 "CREATE SYSTEM TEMPORARY TABLESPACE ICMLSSYSTSPACE32 PAGESIZE 32 K MANAGED BY SYSTEM USING ('icmlssystspace32') BUFFERPOOL ICMLSMAINBP32" 
db2 "CREATE SYSTEM TEMPORARY TABLESPACE ICMLSSYSTSPACE4 PAGESIZE 4 K MANAGED BY SYSTEM USING ('icmlssystspace4') BUFFERPOOL ICMLSVOLATILEBP4" 

db2 "DISCONNECT jcrdb" 
db2 "TERMINATE"

Note : Depending on the environment you are setting up you may need to tweak the above scripts a little like increasing the pagesize etc. to achieve the desired level of performance. You can migrate all the Portal DB's into one DB as well but its recommended to have each of them separately for better performance.
