Ensure that replication on the slave is caught up to the last change on the master. 3. stop binary logging on the master. 4. stop replication on the slave. 5. dump the master, stop old 4.1 server, start new 5.1 server and reload master dump file under 5.1 server ( binary logging is turned off) 6. dump the slave, stop old 4.1 server, start new 5.1 server and reload slave dump file under 5.1 server. 7. After loading is complete, test then start binary logging on master while still preventing updates to updates. 8. After loading slave, test then start slave (get configs in place and restart server). I am thinking that in this scenario I dont have to bother with recording binlog file names and position etc etc. That both servers will have the same databases abd replication and binary logging will start on the two databases with no data loss and continue forward.

FW: cache-panel DB issue
I am trying to move my cache into ndb but when I use the ndb engine the query time is 4 min versus myisam which is 7 seconds. This is due to the fact it is doing a full table scan on ndb and an index on myisam. I was hoping someone could help me fix this or at least explain why this is happening. I have included the select statements , the select statement and the explain select for both the ndb and the myisam. Cache database (ndb) Select distinct t0.panelId from cache1 t0, cache2 t1 where t0.panelid=t1.panelid; (282.54 s) CREATE TABLE `panel`.`cache1` ( `panelId` int(11) DEFAULT NULL, KEY `panelid` (`panelId`) ) ENGINE=ndbcluster DEFAULT CHARSET=utf8; CREATE TABLE `panel`.`cache2` ( `panelId` int(11) DEFAULT NULL, KEY `panelid` (`panelId`) ) ENGINE=ndbcluster DEFAULT CHARSET=utf8; Explain select distinct t0.panelId from cache1 t0, cache2 t1 where t0.panelid=t1.panelid; ++-+---+--+---+-+-+- -++-+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | ++-+---+--+---+-+-+- -++-+ | 1 | SIMPLE | t0| ALL | panelid | NULL| NULL| NULL | 534063 | | | 1 | SIMPLE | t1| ref | panelid | panelid | 5 | cache.t0.panelId | 1 | Using where | ++-+---+--+---+-+-+- -++-+ Panel database (myisam) select distinct t0.panelId from cache3 t0, cache4 t1 where t0.panelid=t1.panelid; (6.5 s) CREATE TABLE `panel`.`cache3` ( `panelId` int(11) DEFAULT NULL, KEY `panelid` (`panelId`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; CREATE TABLE `panel`.`cache4` ( `panelId` int(11) DEFAULT NULL, KEY `panelid` (`panelId`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; explain select distinct t0.panelId from cache3 t0, cache4 t1 where t0.panelid=t1.panelid; ++-+---+---+---+-+-+ --+++ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | ++-+---+---+---+-+-+ --+++ | 1 | SIMPLE | t0| index | panelid | panelid | 5 | NULL | 534053 | Using index; Using temporary | | 1 | SIMPLE | t1| ref | panelid | panelid | 5 | panel.t0.panelId | 1 | Using where; Using index; Distinct | ++-+---+---+---+-+-+ --+++ Thanks Joshua Gordon
Tools on http://www.severalnines.com do not work.
Hi List, I have been trying to use bencher and chkfrag from http://www.severalnines.com. But I continue to receive the following errors../chkfrag: error while loading shared libraries: /usr/local/mysql/lib/libndbclient.so.4: cannot restore segment prot after reloc: permission denied. I am running this with NDB 7.0.6 and the owner of the library is mysql.mysql. Any ideas? Thanks Joshua Gordon.
binlog questions
We outputted the bin log using the following command: mysqlbinlog -v --base64-output=DECODE-ROWS oo-mysql1-bin.87 We then looked in this file and found some odd things. For example there is the below insert statement: ### INSERT INTO panel.history ### SET ### @1=-182667600 (4112299696) ### @7=NULL The table structure for history is: CREATE TABLE `history` ( `historyid` int(11) NOT NULL AUTO_INCREMENT, `panelid` int(11) DEFAULT NULL, `projectid` int(11) DEFAULT NULL, `resultid` int(11) DEFAULT NULL, `pulldate` datetime DEFAULT NULL, `resultdate` datetime DEFAULT NULL, `senddate` datetime DEFAULT NULL, `sendcount` int(11) DEFAULT NULL, `bouncecount` int(11) DEFAULT NULL, `link` char(128) DEFAULT NULL, `projectgroupcode` int(11) DEFAULT NULL, `vendorid` int(10) unsigned DEFAULT NULL, `ipaddress` char(15) DEFAULT NULL, `enddate` datetime DEFAULT NULL, `bloodhoundid` int(10) unsigned DEFAULT NULL, `incentive` int(4) unsigned DEFAULT NULL, PRIMARY KEY (`historyid`), KEY `RESULTDATE` (`resultdate`), KEY `PULLDATE` (`pulldate`), KEY `PANELID_PROJECTID` (`panelid`,`projectid`), KEY `PROJECTGROUPCODE` (`projectgroupcode`), KEY `projectid_vendorid` (`projectid`,`vendorid`), KEY `PROJECTIDb` (`projectid`) USING BTREE, KEY `bloodhoundid` (`bloodhoundid`) ) ENGINE=ndbcluster DEFAULT CHARSET=latin1 So it is trying to put a negative value in for the first column? Then you have stuff like: ### INSERT INTO panel.history ### SET ### @1=1169499418 ### @7=348123-41-35 05:64:02 That looks valid but there is no row in the history table with that historyid so why isn't it there? all in all it seems very inconsistent with the columns it uses and what shows up etc.. any insight would be appreacited thank you. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org
