The JDBC driver may be upgraded if a newer version has been made available by the database vendor. The driver may need to be updated if the vendor recommends new driver or if the database has been upgraded.
Download the drivers directly from the DB vendor site. Remove the old JDBC jar file from this directory:
Note: Do not rename, remove or delete the JDBC jar file from agent directory
Copy the <jdbc_file_name>.jar to the following directory
Each vendor names the files differently. Refer to DB vendor for exact filename and version. Here are filenames of commonly used drivers (names may change):
Oracle : ojdbc[N].jar E.g. ojdbc7.jar
MS-SQL: sqljdbc[NN].jar E.g. sqljdbc42.jar
IBM DB2: db2jcc.jar and db2jcc_license_cu.jar (two files)
