I just went through an installation of ARS 7.6.04 SP4 on RHEL 6.0 and discovered that the install would fail. The installation logs show that the Remedy process failed to start. After checking to see if the binaries and the Remedy meta-tables did get installed indicating that at least the RDBMS user ARAdmin was successfully connecting to the database, I tried starting just the arserverd instance. Trying different settings it appears that having portmapper selected prevented the installation from completing.
Post installation testing involving creation of Activelinks from DevStudio 7.6.04 SP4 generated the following error.
“ERROR (150): A server name must be supplied in the control record”
