# Advantages

A few of the advantages of using the TIBCO Mainframe Logger are listed below:

1. It can write many thousands of messages every second to the IBM z/OS System Logger. Data can be written from TIBCO Substation ES, CICS, TSO, REXX, IMS, or from a job, or task transaction from an LPAR to a single mainframe logger stream. This when configured correctly, has no point of failure.
2. It removes the responsibility for saving the log data (with the requested persistence), retrieving the data (potentially from any system in the sysplex), archiving the data, and expiring the data from the creator of the log records.
3. It provides the ability to have a single, or merged log that contains log data from multiple instances of an application within the sysplex.
