Example of a Python Program (example.py)

import os

import sys

import string

if __name__ == '__main__':

#Define SQL statements

reorgtable="REORG TABLE neo.persnl.employee";

updatestats="UPDATE STATISTICS FOR TABLE neo.persnl.employee "

updatestats=updatestats + "ON EVERY COLUMN";

selecttable="SELECT COUNT(*) FROM neo.persnl.employee";

#Contruct a list of SQL statements to be executed

stmnt = [reorgtable,updatestats,selecttable]

print "\n";

for stmntstr in stmnt:

cin, cout ,cerr = os.popen3('python /usr/local/hp/nvscript/bin/hpnvs.py "'+stmntstr+'"')

while 1:

text = cout.read()

if text:

print text

else:

break

while 1:

text = cerr.read()

if text:

print text

else:

break

cin.close()

cout.close()

Running the Perl or Python Program

Before running the Perl or Python program, make sure that you included the absolute path of

the Perl or Python wrapper script (hpnvs.pl or hpnvs.py) in the program file:

• On Windows:

hpnvs-installation-directory\nvscript\bin\hpnvs.pl

hpnvs-installation-directory\nvscript\bin\hpnvs.py

hpnvs-installation-directory is the directory where you installed the Neoview

Script software files. For more information, see Table 2-1 (page 34).

• On Linux or UNIX:

hpnvs-installation-directory/nvscript/bin/hpnvs.pl

hpnvs-installation-directory/nvscript/bin/hpnvs.py
