Performing Tasks Before Upgrading

To ensure a successful upgrade, review and perform preparatory tasks as necessary. Depending on the old server configuration, you may not need to perform all preparatory tasks.

Prerequisites
Task
Note: Follow these steps only if you are upgrading from an earlier version non-clustered Adaptive Server to Adaptive Server Cluster Edition version 15.7 SP100; these steps do not apply if you are upgrading from an earlier version of Adaptive Server Cluster Edition

Skip these preparatory tasks if you plan to use sqlupgrade, which performs these tasks automatically.

  1. Install Adaptive Server 15.7 SP100 into its own installation directory.
  2. Check system and upgrade requirements.
  3. Verify the name and location of the runserver file, as well as that you have renamed it to RUN_servername, where servername is the name of the old server, as it appears in the interfaces file.
    The default RUN_servername file for a server SYBASE is called RUN_SYBASE. If the RUN_servername file for your current server is named differently, use the actual name of your server during the upgrade process.
  4. While the upgrade process for Adaptive Server requires that the previously installed version of the server is running, the upgrade process for Backup Server, Historical Server, and XP Server, requires those servers to be shut down.
  5. Verify that the text of all stored procedures you upgrade is available in syscomments by either:
    • Reinstalling the procedures with text, or,
    • Removing and reinstalling the procedures after the upgrade.
    This step can allow you to inspect the stored procedures for any hidden or unwanted text.
  6. Make sure reserved words use quoted identifiers.
  7. Verify that users are logged off.
  8. Use dbcc to check for database integrity.
  9. Back up databases.
  10. Dump the transaction log.
  11. Verify that master is the default database for the "sa" user.
  12. Prepare the database and devices for upgrade using the preupgrade utility:
    1. Create a sybsystemdb database if it does not already exist.
    2. Disable auditing by running sp_configure 'auditing', 0.
    3. Disable Job Scheduler.
    4. Obtain the current audit settings for the pre-15.7 Adaptive Server using sp_displayaudit; use this saved information to reenable auditing after you complete the installation. See Reenabling Auditing.
    5. If you made any site-specific changes to the permissions for system stored procedures, obtain the current permission settings for them using sp_helprotect; then use this saved information to reenable the permissions after you complete the installation. Pay special attention to:
      • Any stored procedures that are not granted execute permission to public, such as sp_addauditrecord, sp_monitor, and sp_sysmon.
      • Any stored procedures where execute permission has been revoked from public.
    6. Disable disk mirroring.
      Note: Cluster Edition version 15.7 SP100 does not support disk mirroring.
    7. Verify that your SYBASE environment variable points to the location of the new server software files you just installed.
    Fix any problems that preupgrade utility reports.

    You can safely ignore any warnings Adaptive Server issues about configuration parameters not being set to the default, as these are only for your information.

  13. If you are upgrading from a nonclustered 12.5.4, 15.0.2, or 15.5 server, and archive database access has been applied in the lower version server, disable the related functionality before upgrading.
  14. If you are upgrading from a 12.5.4 installation with cache bindings on sybsystemdb, drop the cache bindings for sybsystemdb that are bound to user-defined caches before running the preupgrade utility.
    If you do not do this, you see this error: 
    Current process... infected with 11
    If you receive this error, re-run the preupgrade utility after you have dropped the cache bindings.
  15. Ensure that the procedure cache size is at least 150 percent of the default procedure cache size, or between 53,248 and 2,147,483,647 2K pages.
  16. Copy these files from earlier versions of the server to their corresponding Adaptive Server 15.x installation locations:
    • $SYBASE/interfaces
    • $SYBASE/$SYBASE_ASE/servername.cfg – where servername is your server name.
    • $SYBASE/$SYBASE_OCS/config/libtcl.cfg
    • $SYBASE/SYSAM-2_0/licenses/license.lic
  17. If you have enabled the Java in the database feature, create the sybpcidb database and disable the feature during the installation.
  18. Set the OLDSYBASE_ASE variable to the SYBASE_ASE appropriate to your older server. If you are upgrading from 12.5 for example, it should be ASE-12_5.
  19. When you upgrade a server to the Cluster Edition, index and table-level statistics become inaccurate, and must be updated. Execute update index statistics on these tables:
    • sysobjects
    • sysindexes
    • syscolumns
    • systypes
    • syslogins
    • sysusers
