# /sbin/sysctl -w kernel.shmmax=nnn
Note: The default operating system shared memory for some older Linux releases is
32MB. The minimum required by Adaptive Server is 64MB for a default server with 2K
pages. A higher value is required if you plan to increase the Adaptive Server max.
3.
To guarantee that the minimum operating shared value is applied every time the system is
started, edit the /etc/sysctl.conf file.
4.
On Linux RHEL 5 and greater, Adaptive Server version 15.x running on multiple engines
requires the security feature Exec-Shield to be disabled. To disable Exec-Shield:
a) Add the following lines in /etc/sysctl.conf:
kernel.exec-shield=0
kernel.randomize_va_space=0
b) As super user (root), for the action to take effect, enter:
/sbin/sysctl -P

Managing Java in the Database During Installations and Upgrades
If you have enabled the Java in the database feature, create the sybpcidb database before
installing or upgrading to Adaptive Server version 15.7 ESD #2.
1.
Create the sybpcidb database. The sybpcidb database stores configuration
information for the pluggable component interface (PCI) and all pluggable component
adapter (PCA) components. This database is used by the installpcidb script. For
example:
1> disk init
2> name = "sybpcidb_dev",
3> physname = "${SYBASE}/data/sybpcidb_dev.dat",
4> size = "24M"
5> go
1> create database sybpcidb on sybpcidb_dev = 24
2> go
The device and database sizes depend on the Adaptive Server page size:
• 2K page size – 24MB
• 4K page size – 48MB
• 8K page size – 96MB
• 16K page size – 192MB
2.
Disable the Java in the database feature:
1> sp_configure 'enable java', 0
2> go
3.
Reenable the feature after you have successfully installed or upgraded to Adaptive Server
15.7 ESD #2:
