IBM Docs 2.0

If you have the following errors in your docs SystemOut.log

error when executing SQL:SELECT * FROM “CONCORDDB”.”DOC_HISTORY” WHERE “REPO_ID” = ? and “URI” = ? [jcc][10150][10300][3.65.110] Invalid parameter: Unknown column name DOC_ID. ERRORCODE=-4460, SQLSTATE=null

or if sometimes the docs displays a “Conversion server not available” error although the viewer displays the file.

Then maybe you have forgotten to upgrade the DB Schema while updateing Docs. Running the / upgradeSchema.bat is your friend.
