Example 4 with VariableType

use of org.activiti.engine.impl.variable.VariableType in project Activiti by Activiti.

Example 5 with VariableType

use of org.activiti.engine.impl.variable.VariableType in project herd by FINRAOS.

the class HerdProcessEngineConfigurator method configure.

@Override
public void configure(ProcessEngineConfigurationImpl processEngineConfiguration) {
    // There is an issue when using Activiti with Oracle. When workflow variables have a length greater then 2000 and smaller than 4001,
    // Activiti tries to store that as a String column, but the Oracle database column length (ACT_RU_VARIABLE.TEXT_, ACT_HI_VARINST.TEXT_) is 2000.
    // Since Activiti uses NVARCHAR as the column type which requires 2 bytes for every character, the maximum size Oracle allows for the column is
    // 2000 (i.e. 4000 bytes).
    // Replace the StringType and LongType to store greater than 2000 length variables as blob.
    VariableTypes variableTypes = processEngineConfiguration.getVariableTypes();
    VariableType stringType = new StringType(2000);
    int indexToInsert = replaceVariableType(variableTypes, stringType, 0);

    replaceVariableType(variableTypes, longStringType, ++indexToInsert);
