IBM DB2 UDB JDBC Drivers - What are you using ?
   

Having an interesting conversation on Skype re a JDBC driver issue from IBM Tivoli Directory Integrator 7.0.0.5 to IBM DB2 UDB 9.7.0.2

Cannot load JDBC driver class 'com.ibm.db2.jcc.DB2Driver'
java.lang.UnsupportedClassVersionError: (com/ibm/db2/jcc/DB2Driver) bad major version at offset=6


and the question of the JDBC driver version came up.

Did you know ( and I didn''t ) that you can deduce the JDBC driver version by the size of the JAR file e.g. db2jcc.jar etc. from this table: -


So I have DB2 UDB 9.7.0.3 and my dbcjcc.jar is 3,348,681 bytes in size.

That means that it is: -


My correspondent was using DB2 UDB 9.7.0.2 and his JDBC driver was 3,295,950 bytes in size.

Again, this tied up: -


So, a potentially useful way of validating that you have the correct JDBC driver.

Oh, the root cause of the ITDI exception java.lang.UnsupportedClassVersionError  ? Don't yet know, but will report back :-)

#ShellShock - Bash broke my VMware
Mon, Sep 29th 2014 6:25a   Dave Hay
So, to avoid impact by the infamous #ShellShock breach, I removed /bin/bash and, inadvertently, broke VMware Fusion. This is what I see: - VMware Fusion is damaged and could not be repaired. Please move the VMware Fusion application to the Trash and reinstall VMware Fusion. Solution ? Don't remove /bin/bash :-) [read] Keywords: application vmware

IBM BPM 8.5.0 - Updating REST Endpoints programmatically
Fri, Sep 26th 2014 9:25a   Dave Hay
Now I've been seeking a way to achieve this for a wee while now, and finally here it is, thanks in large part to the excellent IBM BPM Community within IBM, many of whom came to my rescue. In essence, I want to be able to update the various REST endpoints within the IBM BPM WAS applications, when I add in IBM HTTP Server ( either co-located or separate ) and HTTP load balancing. This allows the RESTful services to be rendered via the web tier, rather than going directly to the WAS Web Containe [read] Keywords: ibm applications community network password server xml

IBM HTTP Server / IBM Global Security Toolkit - Commanding the line ...
Mon, Sep 22nd 2014 9:05a   Dave Hay
One of my colleagues was looking for inspiration, without too much perspiration, in order to create an SSL/TLS Certificate Service Request (CSR) using IBM HTTP Server and the Global Security Toolkit (GSK). He was hoping to use the GUI tool, IKeyMan, but I tried very hard to persuade him that GUIs are for WIMPs, and that the command-line tool, gskcapicmd is the way to go ( whilst IHS also has ikeycmd, that relies upon a Java Runtime Environment, which may not always be available, especially on a [read] Keywords: admin ibm apple application java network security server websphere wiki
