ASE 15 Upgrade Checklist for Upgrading from ASE 12.x Sybase ASE 15
_________________________________________________________________________________________________
STEP 3.3: UNPARTITION ALL PARTITIONED TABLES
Because of changes to the system tables, and the changes made to support semantic partitioning,
tables that are partitioned on pre-ASE 15.x servers will be unpartitioned during the upgrade process.
Prior to unpartitioning any tables, please be sure to record exactly which tables are partitioned and to
what degree. This can be done by running the below procedure:
1> sp_helpartition
2> go
There are two ways to unpartition your tables:
o
o
o
You can manually execute an alter table unpartition command for every
partitioned user table.
Or, you can execute the following stored procedure:
1> sp_unpartition
2> go
Note: The sp_unpartition procedure is not a normal Sybase system stored procedure, but
documentation for it can be found at the following link:
http://www.sybase.com/files/Technical_Documents/ase15_mig_stored_procs.zip
STEP 3.4: QUIESCE ALL DATABASES
This step is to prevent the occurrence of uncommitted transactions in the log. These can cause
problems during the database upgrade process. This step also helps to ensure overall consistency and
efficiency of the upgrade process.
To quiesce the database, we use the same process as used for performing a Cross-Platform
Dump/Load:
1. Execute dbcc checkdb and dbcc checkalloc to verify the database is clean.
2. To prevent concurrent updates from open transactions by other processes during dump
database, use sp_dboption to place the database in a single- user mode.
3. Flush statistics to systabstats using sp_flushstats.
4. Wait for 10 to 30 seconds, depending on the database size and activity.
5. Run checkpoint against the database to flush updated pages.
6. Run dump database.
