# ln -s myenv-1.0.3 myenv

Upgrade from 1.0.2 or older to 1.0.3 or newer

cd ${HOME}/product/myenv
ln -s ../../utl/oem_agent.php plg/showMyEnvStatus/

. /etc/myenv/MYENV_BASE
cd $MYENV_BASE/bin
. myenv.profile
cd - > /dev/null
# END MyEnv

Changes in MyEnv 1.0.3


  • Comment in aliases.conf and variables.conf more clear to avoid conflicts with shell variables.
  • Commented lines in aliases.conf and variables.conf are ignored.
  • product/lib/mysql path added to LD_LIBRARY_PATH for some set-ups (bug #106).
  • CHANGELOG added.
  • up alias pointing to function in .bash_profile caused troubles in cluster failover. Thus we are using the variables which should always work.

MyEnv Installer

  • Install comments for MyEnv installer improved.
  • root commands changed into sudo commands.
  • basedir is guessed from product directory.
  • New socket candidate added.
  • Kill session procedure added (sql/create_procedures_kill_sessions.sql).

MyEnv Utilities

  • glb_control.shx added. This utility removes or adds a Galera Cluster node from the Galera Load Balancer when the node is not SYNCED.
  • Partition maintenance utilities were improved by adding a new partition merge utility (utl/merge_partition.php). Split partition is one week ahead to avoid huge amount of data copy. Password can be stored in a file instead of providing it on the command line. Options usage is fixed.
  • Better check for invalid options/parameters in utl/slave_monitor.php (bug #114).

MySQL Backup Manager

  • mysql_bman retention time maximum was verified incorrectly.
  • Some typos in usage and error messages fixed.
  • Remove target for type --cleanup, clean-up does not require target.
  • Keys and values trimmed while reading config file.
  • mysql_bman compression can be switched off for de-duplicated drives.
  • mysql_bman considers (user and password) in client and mysqldump section.
  • Separated mysql_bman into php part and bash wrapper.
  • Split mysql_bman code and lib for automated testing.
  • If option was passed twice this lead to strong behaviour (bug #33).
  • backupdir creation error caught more nicely (bug #75).
  • No option --cleanup removes files after archiving to tape (bug #76).
  • Fixed endless loop bug in config read which affected customer.
  • Use readlink if realpath is not available (problem with SLES).
  • Cleanup does only delete bck_* files.
  • No value options (--no-compress, --per-schema, --archive, etc.) in config file works.
  • Example in --help is more clear.
  • Target improved and more easy.
  • Catch parse error on .my.cnf caused by ! in password string.
  • .my.cnf (user, password) is considered and target adapted accordingly.
  • Dump overview feature implemented.
  • Full backup lists all schemas included.
