Sybase database requirements

You can create a domain configuration repository on a Sybase database. Configure the database settings based on requirements specific to the domain configuration repository.

Use the following guidelines when you set up the repository on an Sybase database:

Set the default database for the Sybase database user, else the DefineDomain command fails.

Set the database server page size to 16K or higher. You must set the page size to 16K as this is a one-time configuration and cannot be changed afterwards.

Set the database locking configuration to use row-level locking.

The following table describes the database locking configuration that you must set:

Database Configuration	Sybase System Procedure	Value
Lock scheme	sp_configure "lock scheme"	0, datarows

Set the Sybase database option "ddl in tran" to TRUE.

Set "allow nulls by default" to TRUE.

Turn ON the Sybase database option

select into/bulkcopy/pllsort

. By default,

select into/bulkcopy/pllsort

is turned off in newly created databases.

Enable the "select" privilege for the sysobjects system table.

Create the following login script to disable the default VARCHAR truncation:

create procedure dbo.sp_string_rtrunc_proc as set string_rtruncation on
sp_modifylogin "user_name", "login script", sp_string_rtrunc_proc

The login script is run every time the user logs into the Sybase instance. The stored procedure sets the parameter at the session level. The sp_modifylogin system procedure updates "user_name" with the stored procedure as its "login script". The user must have permission to invoke the stored procedure.

Verify that the database user has CREATE DEFAULT, CREATE PROCEDURE, CREATE RULE, CREATE TABLE, and CREATE VIEW privileges.

Set the database configurations to the recommended baseline values.

The following table lists the database memory configuration parameters that you must set:

Database Configuration	Sybase System Procedure	Value
Maximum amount of total physical memory	sp_configure "max memory"	2097151
Procedure cache size	sp_configure "procedure cache size"	500000
Number of open objects	sp_configure "number of open objects"	5000
Number of open indexes	sp_configure "number of open indexes"	5000
Number of open partitions	sp_configure "number of open partitions"	5000
Heap memory per user	sp_configure "heap memory per user"	49152
Number of locks	sp_configure "number of locks"	500000

You can adjust the recommended values according to operations that are performed on the database.
