376.0. "FUTURS EASE V5.3-2 upgrade." by CURRNT::RUSSELL (Middle-aged Mutant Hero Turtle (UK option)) Fri Sep 21 1990 09:40

    EASE V5.3-2 will be installed on FUTURS on Tuesday, October 16th.
    
    Please plan to be without the cluster for all of that day, although with 
    a bit of luck we should have it sometime in the afternoon.
    
    If your project needs an EASE V5.3 environment, please migrate to
    CURRNT before that date.
    
    ADGTST will be available to continue EASE V5.3-2 testing for two weeks,
    between October 1st and 12th.
    
    Peter.

	EASE V5.3-2 has been installed on FUTURS - here's statement of events that should happen if you want to preserve your data. 1) Before any upgrade of these layered products you should backup the data using the utility provided by the layered product. e.g. RMU/BACKUP database 2) RDO> export database 3) EASE upgrade changes RDB/DBMS/CDD versions 4) RDO> import database - this must also be done for every CDD/PLUS dictionary database in use, and you'll probably need privs such as BYPASS to do it. 5) For CDD/PLUS upgrades, the dictionary databases might have to be exported before the upgrade then imported after the upgrade. You will probably also have to - CDO> verify/rebuild_directory but ALWAYS check the installation guide. These must be done for any EASE upgrade that includes an Rdb and/or CDD/PLUS upgrade. A similar process (DBO/unload,DBO/load) applies to DBMS. If you have forgotten to export/import (or unload/load) your databases and dictionaries, rmu/convert (RDB) or dbo/convert (DBMS) can usually convert a database file structure from the immediately prior version to the current version. It is never guaranteed to work over more than one version, and the utility has been known to fail in the past. If convert fails, you must either build and load databases and dictionaries from scratch, or restore earlier software versions, then redo the upgrade as above. The only safe way of doing this would be to freeze all development work, re-install the old EASE disk, capture the old data properly, redo the upgrade again, and convert again. Now the disclaimer. All the instructions above are my interpretation of the release notes and installation guides for CDD,CDD/Plus,RDB and DBMS. The guides are less than straightforward and I may have got it wrong. I strongly suggest you read the guides for yourself as a check. It may also be necessary to update your product knowledge through training courses. Check the latest training catalogue. Finally, if I have got the instructions wrong, please enter a reply.

    EASE V5.3-2 has been installed on FUTURS - here's statement of
    events that should happen if you want to preserve your data.
    
    1) Before any upgrade of these layered products you should backup the
    data using the utility provided by the layered product.
    e.g. RMU/BACKUP database
    
    2) RDO> export database
    
    3) EASE upgrade changes RDB/DBMS/CDD versions
    
    4) RDO> import database - this must also be done for every CDD/PLUS
      dictionary database in use, and you'll probably need privs such as
      BYPASS to do it.
    
    5) For CDD/PLUS upgrades, the dictionary databases might have to be
      exported before the upgrade then imported after the upgrade.  You
      will probably also have to -
    
    		CDO> verify/rebuild_directory
    		
    				   but ALWAYS check the installation guide.
    
    These must be done for any EASE upgrade that includes an Rdb and/or
    CDD/PLUS upgrade.
    
    A similar process (DBO/unload,DBO/load) applies to DBMS.
