Review the Maximum Heap Size

Review the Maximum Heap Size

Verify that Informatica Services uses the required maximum heap size for the number of users in the domain.
The following table lists the minimum requirement for the maximum heap size settings, based on the number of users and services in the domain:
Number of Domain Users Maximum Heap Size
(1-5 Services)
Maximum Heap Size
(6-10 Services)
1,000 or less 512 MB (default) 1024 MB
5,000 2048 MB 3072 MB
10,000 3072 MB 5120 MB
20,000 5120 MB 6144 MB
30,000 5120 MB 6144 MB
The maximum heap size settings in the table are based on the number of application services in the domain.
If the domain has more than 1,000 users, update the maximum heap size based on the number of users in the domain.
  1. Extract the installation files.
  2. Go to the following directory:<installer files directory>/source/tomcat/bin.
  3. Use a text editor to open the infaservice file.
  4. Search for the following text: INFA_JAVA_OPTS=% INFA_JAVA_OPTS% -XX.
  5. Set the value for -Xmx to the maximum heap size required for the number of Informatica domain users.
    For example, to set the maximum heap size to 3072 MB, use the following configuration:
    set INFA_JAVA_OPTS=% INFA_JAVA_OPTS% -XX:GCTimeRatio=9 -Xmx3072m
