Updating TREX
Use
The update software package of TREX is named TREX Revision. The TREX Revision numbers no longer follow the SP stacks. Nevertheless, you download the TREX Revision update from the SP stack download page as described in section Downloading TREX in order to get the TREX update packages appropriate to the corresponding SP stack.
Prerequisites
You have installed at least one previous TREX 7.10 release (Version 7.10.XX.XX) :
● If you have already installed TREX, refer to the TREX admin tool Landscape → Hosts → Version to find the version of your TREX installation (see Starting the TREX Admin Tool).
● If you do not have TREX installed at all, install TREX 7.10 from scratch as described in this guide in section Installation and Update.
In a distributed scenario, all TREX systems must have the same TREX release with the same patch level. Mixed installations with different TREX releases are not supported.
Procedure
...
1. Log on to the host on which you want to apply the TREX update package as user <SAPSID>adm.
Do not use the <SAPSID>admuser of another SAP system for updating a TREX system.
For a distributed TREX system, you have to perform the update on the TREX host on which the TREX global file system is installed. The TREX instance on this host is to be updated first. With the restart of TREX after the update, all other TREX instances of the TREX system are updated automatically by replicating the updated binaries.
2. Change to the directory <TREX_DOWNLOAD>/ims_sapinst_standalone_trex/<OS_DIR>, which has been created by SAPCAR.
Before starting the update, you have to close the TREX Admintool.
3. Start SAPinst from the directory <TREX_DOWNLOAD>/ims_sapinst_standalone_trex/ <OS_DIR>:
○ UNIX: Entering the command cd <TREX_DOWNLOAD>/ims_sapinst_standalone_trex/<OS_DIR> ./sapinst
○ Windows: Double clicking sapinst.exe in the directory <TREX_DOWNLOAD>/ims_sapinst_standalone_trex/<OS_DIR>
