Configuring resource caching

You can set the resource caching in each Rational® Requirements Composer client. Resources are cached in memory as specified in the Caching Scheme in each client. This can improve the performance of the product. Caching is persisted during each client session only.

Procedure

  1. In the Rational Requirements Composer client, click Windows > Preferences.
  2. In the Preferences window, click the Connections preference.
  3. Select an entry in the Repositories list.
  4. In the Caching Scheme area, select the check box Cache resources from this repository in memory to enable the caching options.
  5. At the Maximum Cache Size field, specify the maximum allocation of memory for the caching. The default value is 8 MB (8388608 bytes). You can modify this with abbreviations, such as:
    • 10k for 10 KB
    • .5g for 0.5 GB
  6. At the Resource Types to Cache field, click Edit to select file types and artifact types. The default selection is All.
  7. To specify a policy for removing files from the memory cache when the maximum allocation has been reached, select an option at the Policy to use for Eviction field.

    Note: The only option for this field in this release is Least Recently Used.

  8. Click Apply or OK to save your changes.
