We have a legacy application, currently using ojdbc6.jar which cannot be upgraded now. However we want to upgrade to Oracle 19c. Can we use ojdbc6.jar with Oracle 19c?
If the answer is no, then can we set compatible to 11.2.0 to be able to use ojdbc6.jar?
Normally you can use older drivers for newer databases. You just can not use the newer features of the newer database. If the driver is really old, the dba can change the sqlnet.ora on the server to allow connections from older versions.
For example: SQLNET.ALLOWED_LOGON_VERSION_CLIENT=11 allows a client from version 11 to connect to the databases.
Better is to make sure the app is upgraded for support of the latest LTS release. In this case that would be 19c. Allowing older versions to connect can have security considerations.
In the jdbc Frequently Asked Questions you will find a lot of information.

I am altering a legacy software implemented with java spring. Now the challenge is I want to determine the appropriate Database that was used during the initial development.
I have seen somewhere on the code that that the hibernate dialect was org.hibernate.dialect.Oracle9Dialect
So i want to use that piece information to determine which version of oracle to install.
Please i am new to Oracle, So a link to an appropriate url will be appreciated.
9 is an older version of Oracle Database that is no longer supported, and it is no longer available for download from Oracle's Database Software Downloads page. The Oracle9Dialect was deprecated back in 2008, so I wish you the best of luck with your legacy work because I'm sure it is long overdue.
You can request version 9 from Oracle if you have a valid Oracle Database product license (any version,) but if you do not, your options will likely only be third party hosts or acquiring installation media for version 9 by some other means. If you are working with an organization that has you supporting this legacy software, you may have some luck looking through old installation media or asking someone who has been with the company for a while.
From Oracle (bottom of Database Software Downloads page):
Oracle Database 10.2 and 11.1 are no longer available for download. The software is available as a media or FTP request for those customers who own a valid Oracle Database product license for any edition. To request access to these releases, follow the instructions in Oracle Support Document 1071023.1 (Requesting Physical Shipment or Download URL for Software Media) from My Oracle Support. NOTE: for Oracle Database 10.2, you should request 10.2.0.1 even if you want to install a later patch set. Once you install 10.2.0.1 you can then apply any 10.2 patch set. Similarly, for 11.1 request 11.1.0.6 which must be applied before installing 11.1.0.7. Patch sets can be downloaded from the Patches and Updates tab on My Oracle Support.
Oracle recently released new version of Application Express 5.1.2 Patch #: 25786300.
After some research I found out that I cannot download this patch without having support account of oracle which requires Support Identifier to get registered does that means that patches are not free and we have to purchase a service to get patches for oracle apex?
Yes - you must have a support contract for incremental patches.
You can, however, download the complete patched 5.1.2 version from Oracle and install it.
My customer has an existing coldfusion server version 5.x running on windows 2003. They would like to upgrade it to windows 2008/12. We are new to coldfusion, hence want to understand if coldfusion 5.x is supported on 2008/12. If not what should be our migration strategy to upgrade to coldfusion 10.x. Stepped or one shot.
Appreciate your time, thanks in advance.
Do you happen to now if imp oracle command is included in the oracle client tools 11g for MAC OS?
Actually I have download the packages but I can't seem to find it and I am wondering if there is a trick for this.
Thank you
What you have downloaded is the 'Instant Client'. This is basically a sub-set of the Oracle client, just for connecting to the database. Find out more.
The Instant Client does not include admin utilities such as IMP. For that you need the standard client, which is basically the full database software. However, 10g was the only version ever available for MAC OS. I guess the demand wasn't there. How many MAC OS servers are there?
Which jdbc driver should be used for connecting with oracle 8i? I am using jdk 1.6 and tomcat.
The choices would be (in the decreasing order of preference):
The JDBC driver that is provided with the database itself. This is typically found in the jdbc/lib directory of your Oracle database home.
The most recent driver for the 8i platform. You can get this from Oracle Technology Network. Use this if are encountering any issues (that are typically not patched in the driver supplied by the database).
The JDBC driver that ships with the application server. This is listed as the last preference, for the 8i platform is quite old, and the drivers supplied would have better characteristics for newer releases like the 10g and 11g platforms.
If you are on Java 1.4 or newer, i.e. Java 1.4/5/6, then use the driver within ojdbc_14.jar instead of classes12.zip. The driver within classes12.zip is meant to be used on versions of Java after 1.2 and before 1.4.
If you do have ojdbc5.jar or ojdbc6.jar (unlikely to be the case for the 8i drivers), then they'll need to used in preference over ojdbc14.jar, in the Java 5 and Java 6 platforms respectively. Use these drivers (meant for the Java 5 and Java 6 platforms) with caution though, as the some of these driver versions will simply not be supported when used against an 8i database. For example, the Oracle® Database JDBC Developer's Guide and Reference for 11g R1 states the following:
Backward Compatibility
The JDBC drivers are certified to work
with the currently supported versions
of Oracle Database. For example, the
JDBC Thin drivers in Oracle Database
11g Release 1 (11.1) are certified to
work with the 10.2.x, 10.1.x, 9.2.x,
and 9.0.1.x Oracle Database releases.
However, they are not certified to
work with older, unsupported database
releases, such as 8.0.x and 7.x.
The JDBC developer's guide for 10g R1/R2 might state the same, but you'll need to verify this if you intend to proceed with a driver version that works against a newer database release. In practice, ensure that you know the version of the driver in use, and that it is supported for use against 8i.
