- Drop Servers of Type asejdbc Before Migrating
SAP Sybase IQ 12.7 Databases to
SAP Sybase IQ
16.0 – The asejdbc server class is
deprecated. Servers of type asejdbc
must be dropped prior to running iqunload.
SAP Sybase IQ 12.7 databases
with remote server definitions based on the
asejdbc driver will not have
these definitions migrated to by the
iqunload tool and will not give
an error at the beginning of an unload saying that you
need to drop any asejdbc servers (if there are any
present).

- Drop all JOIN and all LD indexes. On multiplex, drop all
logical servers named AUTO,
COORDINATOR,
ALL or
DEFAULT – If you do not drop these objects and try to run an
ALTER DATABASE
UPGRADE in
SAP Sybase IQ
16.0, the upgrade
fails and the server returns a message that indicates
that a database upgrade is not possible when these
objects are in use.
- Recovery Infomation – To recover from a failed upgrade, shutdown the
16.0 server, open
the database with SAP Sybase IQ
15.x, and drop all LD and all JOIN indexes as well as any
named logical servers before proceeding with the
migration.

- Cannot Enable Row-level Versioning in Upgraded
Database – If you upgrade a database from 15.x to 16.0, you cannot
enable row-level versioning (using the ALTER
TABLE statement), or perform
LOAD, INSERT
or UPDATE statements on any IQ base
table containing a CHAR,
VARCHAR or
VARBINARY column of width greater
than 255. If your upgraded database contains a table
having a column with these criteria, run the
sp_iqrebuildindex procedure.
After you run this procedure, you can enable row-level
versioning and perform DML statements on these
large-column tables.
