Guidelines for Increasing the Number of DB2 UDB User Processes Under AIX
This topic is part of Configuring an IBM DB2 UDB Database for Siebel Applications. When you reach about 400 concurrent database users running under AIX, the connection to DB2 may fail. To avoid this problem, reset the parameter controlling the maximum number of user processes on your AIX server. To reset the parameter
- Log on to the server as the AIX system administrator.
- Navigate to $SIEBEL_HOME (Siebel Server root directory) and source environment variables, using one of the following commands, depending on the type of shell you use:
Bourne or Korn shell
. ./siebenv.sh
TIP: Make sure there is a space between the initial period and ./siebenv.sh .
C shell
source siebenv.csh
- Execute the following command to review the options:
smitty chgsys
- Select Maximum number of processes and reset the default (
512 ) to a larger number; for example, 10,000, to avoid imposing an upper limit on the number of processes that a single user can spawn.
