Class GenericJDBC

java.lang.Object

org.safs.tools.data.GenericJDBC

public class GenericJDBC
extends java.lang.Object

This class is intended to be a lightweight class with few additional SAFS dependencies.

The purpose is to provide a command-line driven ability to access and update JDBC databases.

JVM Arguments:

• -noupdate
  If present, no attempt to update the data should occur.
  Generally, this is useful for debugging connection attempts/failures.
  Same as JVM Option: -Dsafs.jdbc.noupdate

• -dataid "mydata"
  The data id to be used in our connection queries and updates.
  Same as JVM Option: -Dsafs.jdbc.dataid="<data_id>"

• -datapath "/tst/tools/deploymentdetails/dev/shrdata"
  The data path to be associated with the data_id.
  Same as JVM Option: -Dsafs.jdbc.datapath="'<data_path>'"

• -where "ticketid = 1846"
  The where clause to filter the queries and updates.
  Same as JVM Option: -Dsafs.jdbc.where="<where_clause>"
  Ex: -Dsafs.jdbc.where="ticketid = 1846"

• -dataset "zdeployment"
  The dataset to be updated in the database.
  Same as JVM Option: -Dsafs.jdbc.dataset="<dataset_id>"
  Ex: -Dsafs.jdbc.dataset="zdeployment"

• -field "entminer"
  The field/column to be updated in the dataset.
  Same as JVM Option: -Dsafs.jdbc.field="<field_id>"
  Ex: -Dsafs.jdbc.field="entminer"

• -value "SUCCESS"
  The value to be updated into the field in the dataset.
  Same as JVM Option: -Dsafs.jdbc.value="<value>"
  Ex: -Dsafs.jdbc.value="SUCCESS"

• -connection "sharenet://database.server:5011"
  The value to be used for the JDBC database connection.
  Same as JVM Option: -Dsafs.jdbc.connection="<connection_uri>"
  Ex: -Dsafs.jdbc.connection="sharenet://database.server:5011"

• -props "librefs=mydata '/tst/tools/deploymentdetails/dev/shrdata';undoPolicyNone=True"
  Zero or more name=value pairs (separated by semi-colons) to be used during the connection request.
  This argument can appear more than once, if needed.
  Same as JVM Option: -Dsafs.jdbc.connection.props="<name=value;name=value>"
  Ex: -Dsafs.jdbc.connection.props="librefs=mydata '/tst/tools/deploymentdetails/dev/shrdata';undoPolicyNone=True"

• -opsource "Support:Carl Nagle:org.safs.tools.data.GenericJDBC.java"
  Text to be remotely logged identifying the source of this update request.
  Same as JVM Option: -Dsafs.jdbc.opsource="<text identifying update source>"
  Ex: -Dsafs.jdbc.opsource="Support:Carl Nagle:org.safs.tools.data.GenericJDBC.java"

• -drivers "com.sas.net.sharenet.ShareNetDriver"
  Zero or more jdbc driver class names to append to the jdbc.drivers System property, separated by semi-colons.
  Same as JVM Option: -Dsafs.jdbc.drivers="<driverclass1;driverclass2>"
  Ex: -Dsafs.jdbc.drivers="com.sas.net.sharenet.ShareNetDriver"

This class requires the JDBC Drivers be in the CLASSPATH already.
For example: For SAS/Share, this generally means that both associated JAR files be in the System CLASSPATH ( or passed in the command-line):

• sas.core.jar
• sas.intrnet.javatools.jar
