You can analyze performance data that is produced by CICS® Performance Analyzer for z/OS® and stored in a database such
as DB2®. You must connect to
the database before you can analyze the data, to do this you must
create a credential, a set of information that you use to authenticate
a connection to the CICS PA
plug-in.
Before you begin
See the topic Defining connection credentials in the CICS Explorer® User Guide for further information.
You must have
your database connection details, the correct level of authorization, and be connected to your
company's network.
Note: System connections can now be secured using the SSL protocol. For more
information, see SSL security for Explorer connections, and Managing SSL security
and certificates.

in the CICS Explorer status
bar and the connection icon is green. You can now select data for
