Starting Db2 v12.1:
- TSA (Tivoli System Automation) is the only supported cluster manager on AIX
- Pacemaker is the only supported cluster manager on Linux (On Linux TSA is not supported starting Db2 v12.1)
According to the official documentation only one of three options can be selected:

You can't specify NOTSAMP and NOPCMK in the same command anymore:
- NOTSAMP is now AIX only and NOPCMK does not make any sense on AIX
- NOPCMK is now Linux only and NOTSAMP does not make any sense on Linux
The docs could be improved with at least some (1) at the end of NOTSAMP and (2) at end of NOPCMK and then in Notes explained the usage.

Subject: DB2 12.1 Community Edition INSTALL_TSAMP in RSP file not known
Hello,
I downloaded the Db2 12.1 community edition. I tried to install it as I do it normally with command:
./db2_install -b /opt/ibm/db2/V12.1 -p SERVER -y -f NOTSAMP -f NOPCMK
This was working in the early access version od Db2 12.1.
In the current GA version of Db2 12.1 I see the following messages:
[root@db2121 server_dec]# ./db2_install -b /opt/ibm/db2/V12.1 -p SERVER -y -f NOTSAMP -f NOPCMKA response file error occurred. Unknown keyword "INSTALL_TSAMP" at line "6". A major error occurred during the execution that caused this program toterminate prematurely. If the problem persists, contact your technical servicerepresentative.For more information see the DB2 installation log at"/tmp/db2_install.log.1812".
The RSP file looks like this:
[root@db2121 ~]$ cat /tmp/db2_install.5197.rspPROD=DB2_SERVER_EDITIONINSTALL_TYPE=COMPLETE_BASICFILE=/opt/ibm/db2/V12.1PROGRAM=db2_installINTERACTIVE=YESINSTALL_TSAMP=NOINSTALL_PCMK=NOLIC_AGREEMENT=ACCEPT[root@db2121 ~]$
When I remove the INSTALL_TSAMP=NO, it runs without issues. I found, in the documentation that the INSTALL_TSAMP parameter is deprecated but not removed.
Was this parameter removed in Db2 12.1, and is the documentation not updated? Do you see the same issue for your installations?
