Incomplete transactions prevent transaction log renaming

Item Value
SQLCODE -242
Constant SQLE_BACKUP_CANNOT_RENAME_LOG_YET
SQLSTATE WB003
Sybase error code 3206
ODBC 2 State ERROR
ODBC 3 State ERROR

Probable cause 

The last page in the transaction log was read by a call to db_backup. One or more currently active connections have partially completed transactions, preventing the transaction log file from being renamed. Reissue the db_backup call.
