Installation Guide 63
You also can set the OLDSYBASE, OLDSYBASE_ASE, and
OLDSYBASE_OCS environment variable to the location of the
server you are upgrading, to avoid having to type this path when you
run
syconfig.exe .
• Disable Job Scheduler.
For Windows platforms you must specify the location in detail:
a Copy %OLDSYBASE%\%OLDSYBASE_OCS\ini\libtcl.cfg to
%SYBASE%\%SYBASE_OCS\ini\libtcl.cfg.
12 Ensure that the procedure cache size is at a minimum of 150 percent of the
default procedure cache size, or 7500MB.
13 Copy the following files from earlier versions of Adaptive Server to their
corresponding Adaptive Server 15.x installation.
For UNIX platforms:
• $SYBASE/interfaces
• $SYBASE/$SYBASE_ASE/<servername>.cfg
• $SYBASE/$SYBASE_OCS/config/libtcl.cfg
• $SYBASE/SYSAM-1_0/licenses/license.dat
For Windows platforms:
• %SYBASE%\sql.ini
• %SYBASE%\<servername>.cfg
• %SYBASE%\%SYBASE_OCS%\ini directory
Checking system and upgrade requirements
To verify that your system environment is configured correctly:
1 Verify that the computer on which you plan to upgrade the Sybase
products meets the requirements.
2 Determine whether your server supports an upgrade to Adaptive Server
15.0.2.
3 Verify that your operating system is at the proper version level and has all
operating system patches needed for Adaptive Server.
