Content Component

Content Component is an ACI server. For details of changes that affect all ACI servers, see ACI Server Framework.

23.2.0

New in this Release

  • Loading has been optimized for ACLType fields that have also been configured as MemcachedType (see NodetableCacheFields).

    NOTE: This change is only relevant to security models where the DLL load is required for evaluation.

  • The QueryCacheMaxMemKB configuration parameter has been added to the [Security] section. Set this parameter to a value in KB to enable a per-query cache that speeds up security checks for cases where there are many non-unique ACLs in the system (for example, where security is inherited from a top level folder). If the same ACL has already been evaluated during the query, Content does not need to call the security DLL again. You can set QueryCacheMaxMemKB to -1 for an unlimited cache size, or 0 to disable the cache.

    NOTE: This change is only relevant to security models where the DLL load is required for evaluation (for example, there is no need to use this parameter with NT_V4 security).

Resolved Issues

  • In some cases, Content failed to return hits for terms that existed only in the index cache and not in any indexed documents when SearchUncommittedDocuments was set to True.

  • Content could spuriously log an error "Dynterm list is NULL for term". This error tended to happen for terms with a large number (millions) of occurrences, in servers where documents were regularly deleted and the index compacted.

  • When the Active Directory contained a group name that ends with a space character, the Content security index could become invalid after the component was restarted.

  • When the saved best terms cache file was non-valid, the Content application could shut down during a DRECOMPACT operation. Content now automatically rebuilds the cache if it cannot load the saved file.
