Before you begin the upgrade process, install Adaptive
Server 15.0 onto your system.
To ensure a successful upgrade, review the following pre-upgrade tasks and perform them as necessary. Depending on the old server configuration, you may not need to perform all pre-upgrade tasks.
Check system and upgrade requirements.
Check RUN_server file location.
If you are upgrading Adaptive Server, the previously installed version of the server must be running. If you are upgrading Backup Server, Historical Server, Monitor Server, or XP Server, those servers must not be running.
Stored procedure text in the syscomments table is required for upgrade.
Reserved words are resolved using quoted identifiers.
Verify that users are logged off.
Check database integrity.
Back up databases.
Dump transaction log.
Make sure that master is the default database for the “sa” user.
Prepare the database and devices for upgrade using the preupgrade utility.
Create a sybsystemdb database.
Disable auditing using the command:
sp_configure 'auditing', 0
Save the current audit settings for the pre-15.0 Adaptive Server using the command:
sp_displayaudit
Disable disk mirroring.
Verify that your SYBASE environment variable points to the location of the new Adaptive Server software files you just unloaded.
You also can set the OLDSYBASE, OLDSYBASE_ASE, and OLDSYBASE_OCS environment variables to the location of the server you are upgrading, to avoid having to type this path when you run sqlupgrade.
Disable Job Scheduler.
For UNIX platforms:
$SYBASE/$SYBASE_OCS/config/libtcl.cfg
$SYBASE/$SYBASE_OCS/config/libtcl64.cfg
$SYBASE/$SYBASE_SYSAM/licenses/license.dat
Ensure that the procedure cache size is at a minimum of 150 percent of the default procedure cache size, or 7500MB.
