TREX Admin Tool in the SAP System 
Use
There is a tool for administrating TREX in the SAP system. You can use this tool to administrate the queues, monitor TREX, and display information about the components in a TREX system.
The tool contains the most frequently-used functions. More detailed status displays and configuration options are available in the TREX admin tool (stand-alone).
Prerequisites
You are authorized to start the tool. For information on the granting of authorization, see Assigning Roles and Profiles to Authorization Object S_TREX_ADM.
Features
You access the TREX admin tool using transaction TREXADMIN.
The upper window area contains the following functions:
· In the Connection to RFC Server field, use the RFC destination to choose which TREX system you want to administrate.
Once you have selected the RFC destination, the administration areas become active.
· Using the RFC Administration button, you can create a new RFC destination if required, or display and change existing RFC destinations.
The following administration areas are available:
Window |
Description |
Queue Admin |
This window is only relevant if indexing takes place using the queue server. You can monitor queues, configure queue parameters, and troubleshoot here. For more information, see Queue Administration. |
Queue Landscape |
This window is relevant only for distributed TREX systems and only if indexing is done using a queue server. Here you can see the distribution of the queues among the different queue servers. For more information, see Queue Distribution. |
Index Hierarchy |
This window displays the hierarchical structure of the index. You see here the index type of an index. In the case of a split index, you can see which index parts it consists of. |
Index Admin |
This window displays technical information about indexes. For example, here you can see the time of the last indexing, the number of searchable documents, or the disk space taken up by the index. |
Join Index Info |
This window displays technical information about compound indexes and HPA indexes. |
Index Landscape |
This window is only relevant for a distributed TREX system. Here you can see the distribution of the indexes among the different index servers. In addition, you can check the index replication status. For more information, see Index Distribution and Index Replication Status. |
Topology |
This window displays technical information about a TREX system. For more information, see Topology Information. |
Services |
This window displays the load of the TREX servers. For more information, see Server-Related Information. |
RFC Monitoring |
This window displays whether all of the SAP system application servers have a connection to the TREX system. If there are errors here, they can have the following causes: · The application server is communicating through an SAP gateway that has not been started. · The parameters of the RFC destination do not match the TREX configuration. · No TREX RFC server has registered with the SAP gateway.
The window shows only whether the connection from within the SAP system works. It does not display whether the connection works from within the TREX system. The TREX admin tool (stand-alone) displays the complete status of the RFC connection and allows you to configure the RFC connection and correct the error. |
Trace Files |
This window displays the trace files for the TREX servers. By default, the trace files contain all error messages that the TREX servers output. You can display the contents of a trace file by double-clicking it. You can download the trace files. |
Search |
In this window, you can send search queries for test purposes. |
Alert |
This window is used to monitor TREX. Checks are performed periodically and in the event of errors, you can be notified by e-mail. For more information, see TREX Alert Server. |
Reorg |
The reorganization function is currently not available in the SAP system. |
