CLUI command gives Java error

If CLUI (Command Line User Interface) c omm a nds fail with the error: "Exception in thread "main"

java.lang.OutOfMemoryError: Java heap space", you need to increase the Java size by adding new

java options -xms & -xmx for the failed command. Complete the following steps to increase the Java

heap size for a batch ﬁle:

1. Open the batc

h ﬁle from: <install directory>:\Program Files\Hewlett-Packard\Performance

Advisor\cl

ui\<ﬁle.bat>

2. Replace the following line:

%javacmd% -Djava.cmd=%javacmd% -Dinstall.dir="%installdir%" -cp

%classpath

% com.hp.xpsl.clui.XpPaCli %COMMAND% %*

with

%javacmd% -Djava.cmd=%javacmd% -Dinstall.dir="%installdir%" -Xms256m

-Xmx1024m -

cp %classpath% com.hp.xpsl.clui.XpPaCli %COMMAND% %*

Conﬁguring database attributes on the web server

The followi ng parameter is read when the web server service is started: &\hpss\pa\properties\DB-

Parameters.properties

You c an change some items if you need to achieve greater control over a ccess to your data. However,

these parameters and the database engine itself must stay in agreement or undesirable consequences

might result. When changing these values, record the changes in a safe, well-known location. This

protects your data if the ﬁle is subsequently changed. The stored procedures and triggers (Java and

SQL) involved have been tested with Solid’s em bedded database engine for JDBC compliance. The

parameters provides ﬂexibility if you decide to exercise these options. This code has not been tested

recently with other database engines.

This ﬁle is for database-speciﬁc n e eds, and can be e dited by the user only after installation. The web

server must be stopped and restarted after each change.

The following database values are used and set in the shown locations:DataBaseDriver=solid.jdbc.Solid-

Driver

• BaseURL=jdbc:solid://localhost:1313

• DataBaseName=

• UserId=dba

• Password=isoMorph

Use the following formula to determine the disk space requirements for PA XP (based on the number of

arrays, total LDEVs, collection period, and quantit y of performance data):

Free Space = Total free disk space require d in MB

History Length = Length of the performance data history in days

LUNs = Total number of LUNs in the system (include all hosts)

Collection Period =Collectionperiodinminutes

Free Space = 1.65 + ((0.000165) * LUNs * (History Length * 24 ) * (60/Collection))

Collection Period = ((0.000165) * LUNs * (History Length * 24) * 60)/(Free Space - 1.65)
