Getting Around Documentation Errors With Connections Scripts

I’ve been meaning to write this blog for a while.  And by “a while” I mean since v4 of Connections.  IBM supply a series of scripts with the Connections install that are found in the install directory under the folder connnections.sql.  These scripts are used for a variety of things but most people will have to use them if migrating from an earlier version of Connections to a new one.  The scripts are under the database type folder for each application so the scripts for the Blogs database on DB is in


Now you can put those scripts where you want obviously, but that’s where you will find them.  In that folder there are lots of files that are basically a series of SQL commands written out for you.  Each command line terminates with a ; or a @ to identify that’s the end of the command.  When running these commands with db2 you use a different syntax depending on whether the SQL file ends each line in a ; or @.  For example

;  means our command line is written as “db2 - tvf {filename} >{writetoalogfile} “

@ means our command line is written as “db2 -td@ -vf {filename} >{writetologfile}”

Writing to a log file isn’t compulsory but I always do so I can check if the script ran OK.

The problem is that on the  IBM Documentation site they often give the wrong syntax for each database (oh and they aren’t consistent) so on this page the instructions for the profiles database are

“db2 -tvf predbxferxx.sql”

If you run that (and the clue is it takes less than a second which is suspicious) you will see no errors but if you check your log you will see a single line saying

“End of file reached while reading the command”

That basically means we used the wrong line terminator, we told it -tvf so it looked for a ; at the end of each line but if we open the predbxfer45.sql we can see each line ends in @.  If we change the command to

“db2 -td@ -vf predbxfer45.sql”

it runs perfectly.

It would be nice if the IBM documentation was correct but it’s a simple problem to catch and fix.
