Oracle Unified Directory - Version and later
Information in this document applies to any platform.


When installing OUD on AIX using this command

./oud-setup -v --hostname myhost  --ldapPort 4389 --adminConnectorPort 4444 --rootUserDN "cn=directory manager" --rootUserPasswordFile /home/oracle/mypwdfile --no-prompt --noPropertiesFile --cli --baseDN o=group --doNotStart --serverTuning -Xms3000m --enableStartTLS --generateSelfSignedCertificate

the process fails with error message
OUD Instance location successfully created - /my/dir/"
An error occurred while parsing the command-line arguments: An unexpected error occurred while attempting to initialize the command-line arguments: Could not use the provided server tuning settings. You must provide a heap size value smaller than 0 MB.

Using a heapSize smaller than '--serverTuning -Xms3000m' (i.e.: '--serverTuning -Xms1500m') also fails.
Running oud-setup *without* this "--serverTuning -Xms3000m" and the error message does not appear.

It was observed that on other operating systems the identical command using the same server-tuning parameters will succeed.
