Message Oracle PGA-21215 - partner log name mismatch on warm start

ERRORpartner log name mismatch on warm start
CAUSEThe Exchange Log Names (XLN) GDS variable received from the partner LUs RRM contains an LU6.2 log name that is different from that known by the local LUs RRM.
ACTIONThis can happen if the partner LU was cold started and later warm started, all between the times the local LUs RRM was last shut down and warm started. The local LUs RRM is not aware that the partner LU was cold started, and therefore assumes that the partner LUs RRM is using the wrong LU6.2 log name. Verify that this is what happened, and if so, the local LUs RRM can be forced to accept the new LU6.2 log name from the partner LUs RRM by deleting the local RRMs LU6.2 log entry for the partner LU, and then forcing the partner LU to reinitiate the connection to the local LU. For further information on recovery from this error, refer to RRM Recovery in Chapter 12, 2-Phase Commit.
