3> physname = "${SYBASE}/data/sybpcidb_dev.dat",

4> size = "48M"

5> go

1> create database sybpcidb on sybpcidb_dev = 48

2> go

The device and database sizes depend on the SAP ASE server page size. The minimum and default size

requirements for sybpcidb are:

○ 2KB page size server – 48MB

○ (Default) 4KB page size server – 96MB

○ 8KB page size server – 192MB

○ 16KB page size server – 384MB

2. Disable Java in the database:

1> sp_configure 'enable java', 0

2> go

3. Reenable the feature after you have successfully installed or upgraded to SAP ASE 16.0:

1> sp_configure 'enable java', 1

2> go

6.5.3 Multipathing

Multipathing is the ability of a server to communicate with the same physical or logical block storage device

across multiple physical paths between the host bus adapters (HBAs) in the server and the storage controllers for

the device, typically in Fibre Channel (FC) or iSCSI SAN environments. You can also achieve multiple connections

with direct attached storage when multiple channels are available.

Multipathing provides connection fault tolerance, failover, redundancy, high availability, load balancing, and

increased bandwidth and throughput across the active connections. Multipathing automatically isolates and

identifies device connection failures, and reroutes I/O to alternate connections.

Typical connection problems involve faulty adapters, cables, or controllers. When you configure multipathing for a

device, the multipath driver monitors the active connection between devices. Because multipathing is managed at

the device level, when the multipath driver detects I/O errors for an active path, it fails over the traffic to the

device’s designated secondary path. When the preferred path becomes healthy again, control can be returned to

the preferred path. Multipathing prevents single points of failure in any highly available system.

A common example of multipath connectivity is a SAN-connected storage device. Usually one or more Fibre

Channel HBAs from the host are connected to the fabric switch and the storage controllers are connected to the

same switch. A simple example of multipath connectivity is: two HBAs connected to a switch to which the storage

controllers are connected. In this case, the storage controller can be accessed from either of the HBAs that are

providing multipath connectivity.

All OS platforms provide their own solutions to support multipathing. There are numerous other vendors that also

provide multipathing applications for all available platforms, such as:

● AIX – Multiple Path I/O (MPIO)

● HP-UX 11.31 – Native MultiPathing (nMP)

● Linux – Device-Mapper (DM) Multipath
