    redundancy redis master-slave
    I am using redis as a cache server. Can I somehow configure multiple redis servers, that the cache is fully functional (read/write) even if some of them go offline?I looked into master->slave, but the problem I see there is, that if the master fails, and I allow writes to the slaves, they get overwritten once the master is up again. Now the master just serves the old data.The only solution I could come up was disabling write-to-disc, but that sucks as I loose everything if I have to restart the

    mysql replication database-replication master-slave
    Here’s the scenario: I have one MySQL Master and 1 slave. master-slave replication is set and works perfectly. The slave machine crashes. The master machine is still up and running.

Specifically in the case that the master crashes, and the slave has to take over and run pgpool2 as well. Most documentation and examples I have been a

    linux database oracle11g ulimit master-slave
    Is there an issue with “Ulimit -Hn” being set too low (at 1024) when (Oracle recommend 65536)? This is for Oracle 64-bit 11g on Linux 5.It is one of the settings that appears to be woefully short of its recommendation. But I am also aware that the database server in question is an Oracle Data Guard Local Standby and should only really have a connection or two from its Primary database server (to ship the redo logs across).The Local Standby database server has ‘hung’ about 3 times in as many mon

    mysql innodb master-slave
    I have mysql DB on server S1 (mysql version 5.1.41-3ubuntu12.7-log), i have created master-slave for this DB on server S2 (mysql version 5.1.54-1ubuntu4-log). the DB on S1 was using one data file (ibdata). after dumping the DB to S2 i set innodb_file_per_table=1. this made every table to have its own ibd file. now everything went fine and smoothly. but after restarting mysql on S2, i faced a problem with getting this error: Error ‘Unknown table engine ‘InnoDB” on query.
