ODIFY THE

TCP/IP P

ROFILE IN

MVS

The TCP/IP profile contains system configuration statements used to initialize the

TCP/IP address space. Some statements require special considerations when you

are printing from PSF/MVS. The following example shows the specific statements

that require consideration shown in bold:

ACBPOOLSIZE 1000

ADDRESSTRANSLATIONPOOLSIZE 1500

CCBPOOLSIZE 150

DATABUFFERPOOLSIZE 160 32768

The following is a description of each statement that needs special consideration,

the application and the changes they make necessary. Be aware that if you change

any of the values in the TCP/IP profile, you will need to restart TCP/IP in order

for the changes to take place.

DATABUFFERPOOLSIZE defines the number and size of the data buffers. It is

recommended that you specify 160 data buffers and a buffer size of 32768.

SMALLDATABUFFERPOOLSIZE defines the number of small data buffers. It is

recommended that you specify at least 256 small data buffers.

TINYDATABUFFERPOOLSIZE defines the number of tiny data buffers. It is

recommended that you specify at least 256 tiny data buffers.
