Re: MySQL Cluster Manager 1.4.3 has been released
Hi, Sree, I'm taking care of the release now. Docs should be up soon. Daniel On 10/07/2017 6:53 AM, Sreedhar S wrote: Dear MySQL Users, MySQL Cluster Manager 1.4.3 has been released and can be downloaded from the My Oracle Support (MOS) website. It will also be available on Oracle Software Delivery Cloud at http://edelivery.oracle.com with the next monthly update MySQL Cluster Manager is an optional component of the MySQL Cluster Carrier Grade Edition, providing a command-line interface that automates common management tasks, including the following online operations: - Configuring and starting MySQL Cluster - Upgrades - Adding and removing cluster nodes - Adding and removing site hosts - Configuration changes - Backup and restore MySQL Cluster Manager is a commercial extension to the MySQL family of products. More details can be found at http://www.mysql.com/products/cluster/mcm/ A brief summary of changes in MySQL Cluster Manager version 1.4.3 is listed below: Changes in MySQL Cluster Manager 1.4.3 (2017-07-10) This section documents all changes and bug fixes that have been applied in MySQL Cluster Manager 1.4.3 since the release of MySQL Cluster Manager version 1.4.2. Functionality Added or Changed * Agent: CPU usage during idle time for the mcmd agents has been significantly reduced. (Bug #26227736) * Agent: A new error code, Error 7030, has been created for failed ndb_mgmd commands and mysqld queries. (Bug #26160968) * Agent: Added support for the --skip-networking option for mysqld nodes, allowing mysqld nodes of a managed cluster to communicate with client applications using named pipes or shared memory on Windows platforms, and socket files on Unix-like platforms. Notice that, however, communication between mcmd agents and mcm clients using named pipes, shared memory, or socket files remain unsupported. (Bug #25992390, Bug #25974499) * Client: The start cluster --initial command now reinitializes the SQL nodes (if their data directories are empty) as well as the data nodes of an NDB Cluster. A new option, --skip-init, has been introduced, for specifying a comma-separated list of the SQL nodes for which reinitialization is to be skipped. (Bug #25856285, Bug #85713) * Client: Checksum verification has been added for all cluster reconfiguration plans created by the mcmd agents. Checksums for plans created locally are shared among all agents, and when the checksums do not match, the reconfiguration is aborted. This prevents agents from executing different plans. (Bug #23225839) * Files have been removed from the MySQL Cluster Manager + NDB Cluster bundled package, in order to reduce the package size significantly. (Bug #25916635) Bugs Fixed * Agent: When the list nextnodeid command was run against a cluster with the maximum number of nodes allowed, the mcmd agent quit unexpectedly. With this fix, the situation is properly handled. (Bug #26286531) * Agent: For a cluster with NoOfReplicas=1, trying to stop a data node with the stop process command would cause the agent to quit unexpectedly. (Bug #26259780) * Agent: When a data node was killed by an arbitrator in a situation of network partitioning, an mcmd failed to handle the exit report from the node and quit unexpectedly. It was due to a mishandling of the nodegroup information, which this fix corrects. (Bug #26192412) * Agent: A cluster could not be started if a relative path had been used for the --manager-directory option to set the location of the agent repository. (Bug #26172299) * Agent: When executing a user command, the mcmd agent could hang if the expected reply from another agent never arrived. This fix improves the timeout handling to avoid such hangs. (Bug #26168339) * Agent: While running the import config command, the mcmd agents that were present during the earlier dryrun for the import would become silent and then unavailable. This was due to some hostname resolution issues, which has been addressed by this fix. (Bug #26089906) * Agent: A collect log command sometimes failed at the middle with an ERROR 1003 Internal error: No clients connected. It was because the mcmd agent reset the copy completion marker prematurely; the behavior has been stopped by this fix. (Bug #26086958) * Agent: When the mcmd agents' clocks ran out of sync due to time drifts on virtual machines running Windows operations systems and then the clocks ran in sync again, communications among the agents failed. This fix prevents the problem by making the agents use a monotonic timer
RE: MySQL Cluster or MySQL Cloud
Hi Neil, If you use MySQL Cluster then you have synchronous replication between the 2 data nodes which means that if one should fail you're guaranteed that the other contains the effects of every committed transaction and that the change has already been applied and so there is no delay while relay logs are applied before the automatic failover kicks in - which is why it can take less than a second. You also have a good scale-out story with MySQL Cluster as you can just continue to add more nodes (256 in total, 48 of which can be data nodes) withou having to worry about partitioning, failover etc. Regards, Andrew. -Original Message- From: Neil Tompkins [mailto:neil.tompk...@googlemail.com] Sent: 29 April 2013 14:50 To: Andrew Morgan Cc: [MySQL] Subject: Re: MySQL Cluster or MySQL Cloud Hi Andrew, Thanks for your response and the useful white paper.

Re: MySQL Cluster alerts
Hi Bheemsen, looks like a few different things going on there; if you have a MySQL support contract/subscription then it would be worth raising SRs - it doesn't need to be a bug, it's fine tyo ask questions too. A couple of things that spring to mind in-line I am frequently seeing the following alerts in our production MySQL Cluster environment. Do you have any metrics, guidelines and scripts to monitor and fix these alerts? Any help is appreciated. Temporary Tables To Disk Ratio Excessive Excessive Disk Temporary Table Usage Detected Table Scans Excessive Indexes Not Being Used Efficiently If you're using MySQL Cluster 7.2 then you should run OPTIMIZE TABLE for each of your tables (repeat that step whenever you make schemas changes to it, add an index or make very signifficant data changes). This will make the optimizer make better use of available indexes. Use the query analyzer in MySQL Enterprise Monitor (MEM) to see which queries are taking the time as these are likely to be the table scans (full table scans should be avoided as much as possible). You can use the EXPLAIN command to see if individual queries are making use of the available indexes. Try adding new indexes if they're missing for high-running transactions. Thread Cache Size May Not Be Optimal Cluster DiskPageBuffer Hit Ratio Is Low Note that you might observe this after restarting a data node as the cache must be repopulated as queries come in. If you're seeing this at other times or the MEM graphs show that the DiskPageBuffer Hit Ratio is consistently low then consider increasing it... http://dev.mysql.com/doc/mysql-cluster-excerpt/5.1/en/mysql-cluster-ndbd-definition.html#ndbparam-ndbd-diskpagebuffermemory -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql

Re: MySQL cluster for windows
Hello, I think you are asking what is the last version of Cluster that supported Windows. No MySQL release of the Cluster product has ever supported Windows. (We are talking pre-MySQL acquisition days when Cluster was supporting Windows.) MySQL versions 4.1, 5.0 and 5.1 all support Cluster on Mac- Linux - Unix platforms.

Hi everybody I am running linuz AS-4 with 5.0.24 max version MySQL Cluster i am able to create all the table as ndb but when comming to the import i am not able to import 20 lakhs of record for a table.please help to solve the problem . 20 lakhs = 2 million rows? My memory is that cluster can only do operations in batches of about 30,000 rows at a time. So, if that import is using extended inserts (typical if it's a mysqldump output) it won't work.

Re: ~Mysql cluster info~
Good evening - I'd like to chime in saying that I've been using 5.1.7 with a lot of success. I'm sure there's a bit to go with it's development, but half the stuff that the MySQL dev team is working on, we will never use. Your case may vary. I can't speak for the MySQL guys, but as far as my testing is concerned, I've seen 5.1.7 to be very nice so far - specifically in regards to cluster. Thanks -dant Jimmy Guerrero wrote: Hello, Not at this time, currently 5.1 is in Beta. We should see a release candidate soon, but I can't commit to a specific date at this time.

Re: MySQL Cluster - queries execute with 6.60sec delay when one DB node is dead
Hi, This behaviour is due to a bug (#3657) which has been solved and the fix is on its way out. Rgrds Mikael 2004-05-19 kl. 13.35 skrev Maciek Dobrzanski: Hi, I have configured MySQL Cluster on two machines with 2 DB nodes (NoOfReplicas = 2) and 2 MySQL API nodes, one of each node type on both systems. The config is almost the same as the one of 2-node demo. The cluster is working fine as long as all DB nodes are operational, but if one of them is gone (i.e. I shut it down), all queries that are sent to the MySQL API nodes seem to hang for about 6.60sec before they are actually executed. As soon as the dead DB node becomes available again, everything starts to work as it supposed to. If one of DB nodes is dead: mysql SELECT * FROM t; ++---+ | id | name | ++---+ | 2 | test2 | | 1 | test1 | ++---+ 2 rows in set (6.60 sec) with all DB nodes working: mysql SELECT * FROM t; ++---+ | id | name | ++---+ | 2 | test2 | | 1 | test1 | ++---+ 2 rows in set (0.00 sec) It looks like MySQL is waiting for the dead node to respond, gets timed out after about 6 seconds and then requests the answer from the other node. I did not find anything in the Administrator Guide that would say about such behaviour, which makes the cluster rather useless in case of a node crash. Any ideas how to fix it?

Well ... that doesn't tie in with what I'm reading about mysql cluster, namely it being a main memory database where all data is kept in memory. I guess you can probably run multiple instances of the cluster node on one machine, having the data split across them in a fairly transparent manner. However, there is ... very minimal technical information available on mysql.com about exactly what mysql cluster (ie. mysql on top of NDB) is and what it is really designed for. I looked at the NDB API docs in the bitkeeper tree, which help a bit ... but not all that much. It doesn't look like the current ndb code has any PAE support ... at least on Unix. It does some AWE-ish calls on windows but I don't think those are to actually allows more than somewhere between 2 and 4 gigs per process the way it is being used, unless I am missing something. My overview so far is that it is designed for very though transaction rate systems, with a large number of fairly simple transactions, and also possibly systems with a large amount of read activity. All of this needs to be on a moderately sized data set, since the design is based on it being an in memory database. In any case, since the NDB storage engine is used in place of myisam or innodb... even if it could address more memory using PAE, that wouldn't mean other storage engines could. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: MySQL Cluster Software
Tom O'Neill (MySQL User) wrote: I recently saw and article that says MySQL will be shipping its cluster software starting April 14th during the Users Conference Expo this year. Does anyone have any information about this? My company is considering using the Emic clustering software. Has anyone had experience with that? Will the MySQL branded one be better? I've tried to set up EMIC clustering once for an experiment. Unfortunately, it required more system configuration changes that I was willing to implement. Cannot say much about what is coming from MySQL, but being open-source is a big plus. This means quicker user base growth, and wider and more in-depth testing. Additionally, MySQL has a reputation for a quick turnaround on bugs, which is still the case, even though the company has gotten quite a bit bigger and a lot more commercial business-oriented. I would, however, not try to depend on either for your application if at all possible, and build a simple custom solution yourself instead. Clustering for a known system is a much easier problem that building a generic cluster - you can take many application-specific shortcuts that would not be acceptable in a general case. -- Sasha Pachev Create online surveys at http://www.surveyz.com/ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
