[solved] sapinst on AIX5.3 does not listen on SAPINST_DIALOG_PORT

Again, solution first — issue is described below 😉

Solution:

You should use the latest version of java 1.4.2 (in my case 1.4.2_12).

Increase data segment size limit to unlimited by

ulimit -d unlimited


Issue:

starting ./sapinst works perfect, no errors logged, waiting for remote login on ports 21200 and 21212. However netstat -a shows that sapinst only listens on port 21200. Specifying the SAPINST_DIALOG_PORT environment variable does not work, changing to another port even does not work. Another indicator may by, that telnet to the desired port fails with a connection reset by peer.

Try to check your path variable and your JAVA_HOME environment variable. Check the output of the command: java -version.

See the example output below:

**************************** WARNING ******************************
You are currently running with data limits not set to unlimited.
You may experience out of memory(OOM) conditions.
In the event of an OOM error, please increase the data limit value.
You may use "ulimit -d unlimited" to set data limit as unlimited.

java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM AIX 5L for PowerPC (64 bit JVM) build caix64142-20080923 (SR12) (JIT enabled: jitc))

Increasing the data segment size limit to a larger size seems not to solve the problem, finally I set the limit to unlimited as supposed — it worked.
