SAP System ID already in use installing TREX

72 Views

Hi all,

i receive the following error trying to install Netweaver TREX 7.11 on RedHat when I have to specify ID, System Number and mount directory:

An SAP system ID PTR is already in use. DIAGNOSIS: The SAP system ID you chose is already in use on this host. SOLUTION: Enter another SAP system ID for the new TREX system or choose "Update a TREX system" in the SAPinst catalog to update the existing PTR-system.

File _installchecks.log under sapinst directory reports the following:

This is the list of every instance on this host, but i don't understand why sapinst thinks that there is a system named PTR already installed.

Any help is appreciated.
