Get ulimit of a running process in AIX

In RHEL or any recent Linux kernel, getting a running process limit is just a matter of checking /proc/<pid>/limits.

In AIX, it is a bit more complicated.

 

1) Get the process ID

# ps -ef | grep java
jboss 53215284 17301698 0 22:02:42 – 1:29 /usr/java71_64/bin/java -D[Standalone] -server -XX:+UseCompressedOops …

 

2) Convert PID to HEX

# i=53215284; perl -e “printf (‘%x’, $i)”
32c0034

 

3) Grep the PID to get the slot id of threads

# pstat -A | grep -i 32c0034 | more
627 s 273007b 32c0034 unbound other 52 0 10027340 java
720 s 2d00023 32c0034 unbound other 52 0 1002d040 java

 

4) Use the slot id and pass to kdb to get the process limit

# echo “user 627” | kdb | grep rlimit | grep -v “_”
rlimit[CPU]……….. cur 7FFFFFFF max 7FFFFFFF
rlimit[FSIZE]……… cur 7FFFFFFF max 7FFFFFFF
rlimit[DATA]………. cur 7FFFFFFF max 7FFFFFFF
rlimit[STACK]……… cur 02000000 max 7FFFFFFF
rlimit[CORE]………. cur 3FFFFE00 max 7FFFFFFF
rlimit[RSS]……….. cur 7FFFFFFF max 7FFFFFFF
rlimit[AS]………… cur 7FFFFFFF max 7FFFFFFF
rlimit[NOFILE]…….. cur 000007D0 max 7FFFFFFF
rlimit[THREADS]……. cur 7FFFFFFF max 7FFFFFFF
rlimit[NPROC]……… cur 7FFFFFFF max 7FFFFFFF

Simple SSL Perfomance Comparison

Command used to test:

# openssl s_time -connect localhost:$PORT -new

Tomcat APR/Native:
2011 connections in 10.67s; 188.47 connections/user sec, bytes read 0
2011 connections in 31 real seconds, 0 bytes read per connection

JBoss Java connector:
460 connections in 11.01s; 41.78 connections/user sec, bytes read 0
460 connections in 31 real seconds, 0 bytes read per connection

Apache:
2753 connections in 14.43s; 190.78 connections/user sec, bytes read 0
2753 connections in 31 real seconds, 0 bytes read per connection

Weblogic:
797 connections in 3.81s; 209.19 connections/user sec, bytes read 0
797 connections in 31 real seconds, 0 bytes read per connection

Conclusion:

  1. Using APR/Native is better for performance.
  2. Weblogic is quite OK, performance better than JBoss, considering that it is using JDK 6 (will try with JDK 7 & 8 later).

Updates (26 Oct 2016)

Weblogic + JDK 7
1103 connections in 2.86s; 385.66 connections/user sec, bytes read 0
1103 connections in 31 real seconds, 0 bytes read per connection

Weblogic + JDK 8
889 connections in 4.27s; 208.20 connections/user sec, bytes read 0
889 connections in 31 real seconds, 0 bytes read per connection

Testing Tomcat 8 SSL using testssl.sh

Configuration:

Apache Tomcat 8.0.18 + JDK 1.8.0_92

APR/Native SSL Connector defined in server.xml:

<Connector

Remediation:

1) Disable TLSv1, Triple DES
– edit $JBOSS_HOME/standalone/configuration/standalone.xml
<ssl certificate-key-file=”localhost.jks” key-alias=”localhost” protocol=”TLSv1.1,TLSv1.2″ cipher-suite=”TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_DHE_RSA_WITH_AES_128_CBC_SHA256,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_128_GCM_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA”/>
2) Disable client negotiation
– edit $JBOSS_HOME/bin/standalone.conf
JAVA_OPTS=”$JAVA_OPTS -Djdk.tls.rejectClientInitiatedRenegotiation=true”
With above, all OK except “Server cipher order”. Java 8 seems to has added the method SSLParameters.setUseCipherSuiteorder(), but not sure if JBoss has implemented this.

Summary: 

With above configuration, all OK except “Server cipher order” and “Secure Client-Initiated Renegotiation”. Tried with these flags but still client renegotiation NOT OK.
