/opt/all/*foo*

directory part or application name part are not allowed.
NOTE: In above points
foo is only an example and not an actual pattern.
ARIES RC File Search Path
ARIES searches for the resource configuration (RC) file in the following locations in the following order:
• Root directory (
/): system wide ARIES RC file
• Application directory: all directories in the full absolute path of the PA-RISC application
• User’s home directory (value of environment variable
HOME)
In regards to the ARIES RC file search, here are a few points:
1. ARIES option processing is additive in nature. ARIES continues to search the RC file in all search
paths. ARIES options found in earlier RC file matches are overwritten by option values in later RC
file matches.
2. If the value of environment variable
HOME is NULL, or the path is not accessible, ARIES will ignore
the user’s private RC file.
3. If ARIES cannot find or access the RC file in any of the search paths, it will continue with default
values of options.
4. The ARIES RC file search in application directories enables application vendors to ship custom
ARIES RC files with ARIES options values suitable for their particular applications.
Advanced ARIES Options
Most PA-RISC applications run as expected under ARIES with the default values of options. The follow-
ing ARIES options are useful for advanced users who may want to control ARIES resource management
and/or to tune ARIES for their PA-RISC applications.
• To enable or disable ARIES option flags you do not need to specify
ON or OFF keywords. Such
ARIES option flags have optional negation with
no added at the beginning of the ARIES option
name.
For example,
-mem_order will enable (turn ON) and -nomem_order will disable (
turn
OFF) strong memory ordering in ARIES.
• Certain ARIES options which expect numeric values may be passed a case insensitive
default
keyword to reset the corresponding option value to ARIES default value.
• ARIES options which require a numeric value in kbytes for size do not require kbytes keyword.
For example,
-ssz 8192 is valid and -ssz 8192K or -ssz 8192 kbytes are not valid,
and will result in an error.

-[no]amap_smc
[Disables] enables the creation of separate address map data structure for dynamically gen-
erated code by PA-RISC application. Enabling (-amap_smc) this option flag may provide
optimal performance for JVM-like applications.
The default state of this option flag is enabled (
-amap_smc).
-[no]backpatch
[Disables] enables the dynamic patching of branch targets in ARIES translated code blocks.
WARNING: Disabling (
-nobackpatch) this option flag will cause significant performance
slowdown.
The default state of this option flag is enabled (
-backpatch).
-[no]breaker
[Disables] enables the scheduling and optimization of ARIES translated code. Enabling
(-breaker) this option flag is useful only for reducing the ARIES dynamic translation time
although the overall performance may become slower.
The default state of this option flag is disabled (
-nobreaker).
-[no]compat_core
[Disables] enables the generation of PA-RISC application core file with OS version field filled
