Subject [jira] Commented: (JCR-1525) Jackrabbit depends on Oracle driver for BLOB support in Oracle versions previous than 10.2
Date Tue, 08 Dec 2009 08:51:19 GMT

    [ https://issues.apache.org/jira/browse/JCR-1525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12787370#action_12787370
] 

S├ębastien Launay commented on JCR-1525:
---------------------------------------

> Please note that this change is not backwards compatible: the OracleFileSystem class
now does not use special blob handling required for 10R1 and earlier. If you need that, use
the Oracle9FileSystem. We migh want to add this in the RELEASE-NOTES.txt.

Done in revision 888290.

> In Oracle versions previous to 10.2, Jackrabbit explicitly uses a class from the Oracle
driver to provide BLOB support (see OracleFileSystem.init()). This special handling is no
longer necesary for Oracle 10.2+, so we should provide a new implementation. As discussed
on the list, we can create a new class for Oracle 10.2+, make it inherit from DbFileSystem,
and override the createSchema(), and table space related methods, which are the ones that
need special handling. Furthermore, we could refactor the current OracleFileSystem and break
it into two clases, one of them to keep the current behavior and a new one to keep the common
code (which we could rename to OracleBaseFileSystem or similar, to maintain compatiblity with
code that uses OracleFileSystem for versions previous to 10.2). Then we make the Oracle10FileSystem
inherit from the latter.
