Portal server performance is slow About this task If you want to increase the performance of your portal server and you are not concerned about security, you can disable Secure Socket Layer data encryption on the portal server. If you do not want to use Secure Socket Layer communication between Tivoli Monitoring components and the Tivoli Enterprise Portal Server, use the following steps to disable it: 1. In Manage Tivoli Enterprise Monitoring Services, right-click Tivoli Enterprise Portal Server. 2. Click Advanced > Edit ENV file. 3. Find the following line: kfw_interface_cnps_ssl=Y 4. Change the Y to N. 5. Save the file and exit. 6. Click Yes when you are asked if you want to recycle the service. Cannot create a Tivoli Enterprise Portal Server database About this task When using DB2 8.1 or 8.2, you must install the correct fix pack versions of DB2 in order to create a Tivoli Enterprise Portal Server database. These fix pack versions are: v DB2 V8.1 with Fix Pack 10 or higher fix packs v DB2 V8.2 with Fix Pack 3 or higher fix packs Also, on AIX systems, a failure occurs when you attempt to install a Tivoli Enterprise Portal Server with a DB2 database. Using the db2 installation user ID (default is db2inst1), do the following: 1. Stop the DB2 server if not already stopped using the following command: cd /db2inst1/sqllib/adm db2stop 2. Issue the following configuration changes: export EXTSHM=ON db2set DB2ENVLIST=EXTSHM db2set -all 3. Using your preferred editor add the following lines to the /db2inst1/sqllib/ db2profile file: EXTSHM=ON export EXTSHM 4. Restart the DB2 server using the following command: cd /db2inst1/sqllib/adm db2start 5. Restart the Tivoli Enterprise Portal Server using the following command: cd /opt/IBM/ITM/bin ./itmcmd agent start cq For information on how to modify kernel parameters, see "Modifying kernel parameters (Linux)" (http://publib.boulder.ibm.com/infocenter/db2luw/v9/ topic/com.ibm.db2.udb.uprun.doc/doc/t0008238.htm) in the IBM DB2 Database for Linux, UNIX, and Windows Information Center.
