Improving Performance on MySQL/Windows

MySQL can be passed a jdbc option for the Windows local environment that may improve perfomance 30 to 50%.

Try the following values in the config.props file for the DB_URL:

 SINGLE_DB_MODE=true
 DB_URL=jdbc:mysql:///<dbname>?socketFactory=com.mysql.jdbc.NamedPipeSocketFactory
 DB_DRIVER=org.gjt.mm.mysql.Driver
 DB_USER=root
 DB_PASSWORD=
 DB_PREFIX=lb
 DB_PARAM=

This uses Windows Named Pipe function and avoids use of the TCP/IP protocol. It only works when connecting with a local iteration of the MySQL database on WindowsSecond level two text.

Error Connecting to MySQL

LexBIG is distributed with an older version of the Java MySQL driver due to licensing concerns. If LexBIG reports an error concerning establishing a connection to the MySQL server yet the MySQL CLI is able to connect, a new version of Connector/J may be required.

The latest version of Connector/J is available from MySQL.org. The new jar should be placed in the LexGrid/LexBIG/2.0.0/runtime/sqlDrivers/ directory. Remove the existing mm.mysql-2.0.6.jar to ensure that the class loader does not incorrectly load the older driver file.

Generating RRF Files from UMLS

When generating source RRF files from the Metathesaurus, the UMLS Metamorphosys tool should be set to output versionless source abbreviations rather than versioned source abbreviations in any RRF subset to be loaded to LexGrid. Failing to do so will create an incomplete database leaving the association and concept tables empty.
