Port conflict for Portal installation on AIX

[SandipAgarwalla]

Hi All,

We are trying to install WAS & Portal on AIX 5.3 with Oracle as the DB..

As per as the pre-requirement checks for AIX, it has been recomended to

a. Comment out all entries in /etc/services, that collide with the general SAP ports before starting SAPINST

b. Comment out the entries referring to the following ports (xx is the SAP Instance Number):

- 32xx

- 33xx

- 36xx

- 48xx

When we did a check on the AIX OS, many of the ports mentioned above are being used by the OS by default & can not be commented out.

For requirement no A: I have a list of 20-25 port numbers being used a SAP system..All based on instance number..How to decide upon the instance number so that the required ports for SAP will be free??

Regards,

Sandip

The instance number you select will determine which ports are going to be used, for example, if you select instace 12, then the ports that SAP will use are

3212 for SAP System Dispatcher port

3312 for SAP Gateway Central Instance port

3612 for SAP System Message port

4712 for SAP System Dispatcher Security port

4812 for SAP System Gateway Security port

Hi,

Thanks for your reply. I just checked the services file..

Strangely all in the range of 3200-3299 are being used.

Also i found, there are two entries for each of the ports

example---

apparenet-tps 3237/tcp # appareNet Test Packet Sequencer

apparenet-tps 3237/udp # appareNet Test Packet Sequencer

apparenet-as 3238/tcp # appareNet Analysis Server

apparenet-as 3238/udp # appareNet Analysis Server

apparenet-ui 3239/tcp # appareNet User Interface

apparenet-ui 3239/udp # appareNet User Interface

triomotion 3240/tcp # Trio Motion Control Port

triomotion 3240/udp # Trio Motion Control Port

sysorb 3241/tcp # SysOrb Monitoring Server

sysorb 3241/udp # SysOrb Monitoring Server

sdp-id-port 3242/tcp # Session Description ID

sdp-id-port 3242/udp # Session Description ID

timelot 3243/tcp # Timelot Port

timelot 3243/udp # Timelot Port

onesaf 3244/tcp # OneSAF

onesaf 3244/udp # OneSAF

procos-lm 3248/udp # PROCOS LM

ssp 3249/tcp # State Sync Protocol

ssp 3249/udp # State Sync Protocol

hicp 3250/tcp # HMS hicp port

hicp 3250/udp # HMS hicp port

sysscanner 3251/tcp # Sys Scanner

sysscanner 3251/udp # Sys Scanner

dhe 3252/tcp # DHE port

How to choose the required port for the dispatcher port?

I just checked for instace number 06,

the entry in services file says,

ironmail 3206/tcp # IronMail POP Proxy

ironmail 3206/udp # IronMail POP Proxy

Please help me out .

You would be using the tcp ports, thus

3212/tcp for SAP System Dispatcher port

3312/tcp for SAP Gateway Central Instance port

3612/tcp for SAP System Message port

4712/tcp for SAP System Dispatcher Security port

4812/tcp for SAP System Gateway Security port

if your instance number is 12.

In your post you state that you checked for instance number 06 and found that port 3206 was already used by application ironmail. So pick a different instance number for you installation, making sure that those ports are available before you start the install.

Dear Sandip,

Just edit /etc/services file and mark as comment the ports which are conflicting while doing installation and continue the installation.

Hope this will help.
