This Hot Fix includes the following fixes:

- Issue OSPST-563 - Fix iterator logic so that client does not have to finish the iteration
             or close the iterator before starting a new query.
 - Issue OSPST-562 - Fix relationships for Zone, Horizon and MarkerCollections
 - Issue OSPST-568 - Creating 2d seismic horizons is much faster (e.g. CopyManager workflows when
                     copying data to Studio). Also, the CopyManager copy batch sizes of many seismic
                     and interpretation entities were changed to 100 instead of the default of 1000
                     so now it requires less memory when copying large amounts of data to Studio.
                     Faster performance will also be achieved if running the Studio data connector on
                     a PC that has at least 32GB of memory. The more available RAM the better so try
                     to minimize the number of running applications during the copy operation. Also,
                     if possible, use a Studio 'admin' account when running the Studio data connector
                     if copying to Studio Oracle projects. This increased the copy performance by 20-30%.
                     Use the OpenSpirit User Setup Wizard to specify an 'admin' account for the Studio
                     Data Sources and Projects that will be specified as the CopyManager target project.
 - Issue OSPST-573 - Fixed a problem which would occur if a limited-permission login account ran a scan
                     or copy job using Microsoft Scheduled Tasks. Microsoft lowers permissions levels
                     for processes started via Scheduled Tasks, and the Studio data connector was getting
                     an error trying to retrieve available memory. This is now fixed.
 - Issue OSPST-545 - Big performance improvement for long running queries (e.g. ScanUtility and 2d horizons).
                     A query to retrieve all 2d horizons in a project previously took 5 hours and now only
                     takes 2 hours.
 - Issue OSPST-546 - Fixes for reading and writing 3D volumes so that we can get full clipping range of sample
                     values with any storage format.
 - Issue OSPST-550 - Improved SEGY reading performance.
 - Issue OSPST-555 - Fixed problems in certain CopyMgr workflows when the target Studio grid is created with
                     a SpatialLattice.OriginalCRS that has a XY surface unit that is not 'meters'. This fixes
                     the bug in the bulk Grid2dAccessor GetLocations method that always returned the XY surface
                     values in meters even though the associated CRS has a different surface unit (e.g. ftUS).
                     Now the XY values are correctly unit converted before returning to the client application.
 - Issue OSPST-558 - Major performance improvements. The Studio SDK maximum cache size is now based on the
                     client's PC available RAM (random access memory) instead of being hardcoded. The more
                     available RAM the larger the maximum cache size. This makes a huge difference when running
                     the ScanUtility or DataSelector or any client application that retrieves large amounts of
                     Studio data.
 - Issue OSPST-560 - Enhanced error message to include file path when unable to access specified SEGY file.
 - Issue OSPST-561 - A mechanism has been added to the Studio 2017 and 2018 data connectors to allow custom
                     WellLog mnemonic mappings using the Petrel LogNamesToPropertyTypeCatalog xml file. This
                     mechanism allows mnemonics unknown to Petrel to be mapped to a known template. Contact
                     OpenSpirit Support for more details.
 

Installation

OpenSpirit Runtime version v4.3.0
# NOTE: Runtime-v4.3.0 is a prerequisite *before* installing the new data connector.

OpenSpirit Data Connector for Studio v3.8.0 only

Installation instructions:
1) Shut down all instances of any OpenSpirit related process running from each
   OpenSpirit installation to be updated. Windows master installations should
   shut down the SharedServer services.

2) Update all installations. Use the OpenSpirit "installconfig" utility to import the
   new Data Connector to your master installation. See the installconfig documentation
   for information and instructions.

At this point you can re-start any OpenSpirit process. 

TIBCO OpenSpirit Data Connector for Studio v3.8.0 HF03 is a patch version of the Studio Data Connector. The data connector package ("Studio_v3_8_0_112.osp_pkg") needs to be imported and installed like any other data connector update. This is a cumulative hotfix.
