The activemq script produces an error when run on HP-UX due to an unsupported option: "ps: illegal option – o"


If you use either of the following scripts on an HP-UX IPF system running SAS® 9.4M7 (TS1M7), an error occurs:

The script produces an error. This issue occurs is due to an unsupported option contained in the activemq script. The error is similar to the following:

[exec] ps: illegal option – o
[exec] usage: ps [-edaxzflP] [-u ulist] [-g glist] [-p plist] [-t tlist] [-R prmgroup] [-Z psetidlist]

Note that the appsrvconfig.sh script calls the activemq script, which is also why this error occurs.

For example, you can encounter this issue when you try to use the activemq script to check the status of the SAS JMS Broker, such as the following:

[tevh6i9401]>pwd
/install/cfgsas1/EBI22W08/config/Lev1/Web/activemq
[tevh6i9401]>./bin/activemq status
INFO: Loading '/install/cfgsas1/EBI22W08/config/Lev1/Web/activemq/bin/env'
INFO: Using java '/install/cfgsas1/EBI22W08/SASHome/SASPrivateJavaRuntimeEnvironment/9.4/jre/bin/java'
ps: illegal option – o
usage: ps [-edaxzflP] [-u ulist] [-g glist] [-p plist] [-t tlist] [-R prmgroup] [-Z psetidlist]
ActiveMQ not running

In this scenario, this error occurs because the -o option is not a supported option for the ps command on HP-UX IPF. The activemq script contains the following line when checking if the activemq process is already running:

local RET="`ps -eo "pid,args" | grep "^\s*$activemq_pid\s.*java"`"

As a result, whichever script you are using fails with the error mentioned above.

Workaround

To circumvent this issue, modify the line listed above (or comment it out and add in the line below), so that it looks similar to the following:

local RET=`UNIX95=1 ps -eo "pid,args" | grep "^ *$activemq_pid .*java"`
