Trex for Linux

[Former Member]

One of the worlds largest electricity utilities is concerned that they were told yesterday that Trex 7.1 does not support Red Hat.

I looked through the forums for a while and was not able to find out if this is valid or not.

I also don't know what Trex is but the customer is concerned about this.

Can someone make me smarter as to what Trex is and if it is relevant that it may not support Red Hat?

Thanks.

I'm attempting to resolve the question of OS direction. I am quiet aware of what is available in the PAM. Will trex 7.2 run only on Suse? We are also interested in hana as a future option in our bw/bobj environment. If I need to fight the battle to get suse in the house then I need to know the direction SAP is taking with future development.

Thanks,

hana is an appliance where you do not have to care about the OS

I will be installing trex 7.1 for succession planning and my OS options are windows or redhat. Why would SUSE be required for embedded search and not redhat? If suse is my only option for embedded search then I'll have to go with windows which I really don't want to do. Can someone shed some light on this for me?

Have you checked the SAP PAM (https://service.sap.com/pam) already?

Hi everyone,

TREX in general does support RHEL.

However, TREX in Embededded Search scenarios for ECC 6.0, EhP4 ("Business Suite 7") recommends to use SLES, as a potential later upgrade to SAP NetWeaver Enterprise Search 7.2 will require SLES.

I found this as well which seems to indicate that Trex 7.1 only supports msft and Novell for x86_64:

I am wondering if this is something that a customer should be concerned about and why Red Hat is not included in the supported list.

I have to say that I really have no idea what Trex is and appreciate someone's help with this

Thanks

Hi Mike

TREX is a search engine in the SAP NetWeaver integrated technology platform produced by SAP AG. The TREX engine is a standalone component that can be used in a range of system environments but is used primarily as an integral part of such SAP products as Enterprise Portal, Knowledge Warehouse, and Business Intelligence (BI, formerly SAP Business Information Warehouse). In SAP NetWeaver BI, the TREX engine powers the BI Accelerator, which is a plug-in appliance for enhancing the performance of online analytical processing. The name "TREX" stands for Text Retrieval and information EXtraction, but it is not a registered trade mark of SAP and is not used in marketing collateral

TREX supports various kinds of text search, including exact search, boolean search, wildcard search, linguistic search (grammatical variants are normalized for the index search) and fuzzy search (input strings that differ by a few letters from an index term are normalized for the index search). Result sets are ranked using term frequency-inverse document frequency (tf-idf) weighting, and results can include snippets with the search terms highlighted.

Now as the link that you gave says

Trex 7.1 supports Windows and SUSE Linux, it is difficlult to say why it doesnt support Red Hat,May be SAP hasnt come up with a compatible version with Red Hat

Also why do you need TREX in your setup

Hi Mike,

thanks for finding an error in our documentation, I've already informed the colleagues and asked for assitance to fix it. I've had a look to the official SAP Product Availability Matrix (https://service.sap.com/pam) and did a search for TREX 7.0/7.1 and found the following (in case you have no access to the PAM):
