ICH15042A

Explanation
The APPLDATA field of the IRRPLEX_sysplex-name profile,
for this sysplex, indicates non-data sharing mode. This system is
currently changing to a data sharing mode environment. A system in
data sharing mode cannot safely share a database with a system that
is not in data sharing mode.
If the sysplex is changed into
data sharing mode by a system running a release previous to z/OS® R10, the automatic update,
which indicates the new mode in the IRRPLEX_sysplex-name profile,
did not happen, and it is normal to receive this message.
To
ensure that your database avoids corruption you must determine whether
the databases are being shared by other sysplex members that are not
enabled for RACF® sysplex communication.
Systems that are enabled for RACF sysplex
communication are members of the XCF IRRXCF00 group.
First determine
which systems are sysplex members, but not IRRXCF00 group members.
To display sysplex members, enter the following command from the master
console:D XCF,SYSPLEX
To display group members,
enter the following command from the master console:D XCF,GROUP,IRRXCF00
Next
issue an RVARY LIST command from the systems in the sysplex that are
not IRRXCF00 group members. This indicates whether the systems are
using the same databases as the systems within the group. If there
are systems using the same databases, this is because either:The data set name table (ICHRDSNT) of the other systems sharing
the databases did not specify RACF sysplex
communication during IPL (the databases are used in the same mode
as the group). Or,
This sysplex should not be in data sharing mode. Or,
One of the systems specified an incorrect RACF database in the data set name table (ICHRDSNT)

The ICH15041A WTOR is issued after this message to obtain
a response.
Specify CONTINUE if:there are no systems in this sysplex, which are not enabled for RACF sysplex communication, that
use this database.

Specify CANCEL if:the profile is correct, and you must not use the database in data
sharing mode.

System action
The system waits for the reply of the operator.

Operator response
Respond to the ICH15041A message or contact
your system programmer.

System programmer response
If the database is being used by another
system that is not enabled for RACF sysplex
communication (which implies that it can never change out of non-data
sharing mode), and this system is in data sharing mode, the database
becomes corrupted. You must specify CANCEL to protect the database.
You can then either:Issue an RVARY NODATASHARE from the system in data sharing mode,
before trying the RVARY ACTIVE again. Or,
For systems using the database that are not enabled for RACF sysplex communication, but
must be using the same database, update the data set name table (ICHRDSNT),
and then reIPL the updated systems.

If the identified database is not being used by another
system in this sysplex, which is not enabled for RACF Sysplex Communication mode, specify CONTINUE.
After the RVARY, the IRRPLEX_sysplex-name profile
for this system is updated.
If the message indicates the backup
database, and you did not receive this message for the primary database,
then if the backup database is intended to be the same as the primary
database, and you were able to specify ‘CONTINUE’ to this message,
resynchronize the primary and the backup databases using "IRRUT200
PARM=ACTIVATE".Note: Ensure that the database you are using as the
backup database is the correct database to be using with your primary
database. The "IRRUT200 PARM=ACTIVATE" overlays all the data within
the specified backup data set. See z/OS Security Server RACF System Programmer's Guide for
more information about IRRUT200.
If the problem persists, contact
your IBM® support center.
Do
not use RRSF to propagate the RDEFINE, RALTER, and RDELETE commands
to other databases. If automatic command direction is enabled for
the GXFACILI class, use the ONLYAT operand (on the RALTER, RDEFINE,
and RDELETE commands) when you change IRRPLEX_sysplex-name profiles
to prevent this propagation. ONLYAT must be used whether you are altering,
creating, or deleting the class GXFACILI IRRPLEX_sysplex-name profiles
on a local or remote node.
