I have a very simple script that queries from a DB2 table. The script has 3 parts - (i) Sets the db2profile (ii) connects to db2 using credentials (iii) executes the query.This script works fine if i run it manually from the command prompt. However when scheduled in crontab, it proceeds fine upto step (ii) but fails with the error - "SQL1024N A database connection does not exist" just when the query is executed.
I could see from the logs that the db2 connection is indeed made successfully (connection sucess message displays and the return code is 0). But I am note sure why they query fails saying that a DB connection does not exist. Any immediate help is greatly appreciated.
Here is my CODE:
Code:
# Run DB2 profile on PRD
. /home/db2was/sqllib/db2profile
# Connect to Database
db2 CONNECT TO $DATABASE USER $JOB_USER USING $JOB_PASS
RETURN_CODE=$?
if test $RETURN_CODE -ne 0 ; then
echo Script Failed. Error Connecting to Database
exit 9999
fi
#Run SQL
PURGECOUNT=`db2 -x SELECT COUNT\(*\) PURGECOUNT FROM SCHEMA.TABLE WHERE TIME_COLUMN\<$PURGE_TIME WITH UR`
RETURN_CODE=$?
Here is the output from the log files when invoked by the crontab
Code:
++ db2 CONNECT TO DBXX USER USERXX USING PASSXX
Database Connection Information
Database server = DB2/AIX64 9.7.7
SQL authorization ID = XXXX
Local database alias = DBXX
++ RETURN_CODE=0
++ test 0 -ne 0
+++ db2 -x SELECT 'COUNT(*)' PURGECOUNT FROM SCHEMA.TABLE WHERE 'TIME_COLUMN<1385884801949' WITH UR
++ PURGECOUNT='SQL1024N A database connection does not exist. SQLSTATE=08003'
+++ TEMP_RC=4

db2_pclose
DB2_PCLOSE(3) 1 DB2_PCLOSE(3)db2_pclose - Closes a persistent database connectionSYNOPSIS
bool db2_pclose (resource $resource)
DESCRIPTION
This function closes a DB2 client connection created with db2_pconnect(3) and returns the corresponding resources to the database server.
Note
This function is only available on i5/OS in response to i5/OS system administration requests.
If you have a persistent DB2 client connection created with db2_pconnect(3), you may use this function to close the connection. To avoid
substantial connection performance penalties, this function should only be used in rare cases when the persistent connection has become
unresponsive or the persistent connection will not be needed for a long period of time.
PARAMETERS
o $connection
- Specifies an active DB2 client connection.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Closing a persistent connection
The following example demonstrates a successful attempt to close a connection to an IBM DB2 i5/OS database.
<?php
$conn = db2_pconnect('', '', '');
$rc = db2_pclose($conn);
if ($rc) {
echo "Connection was successfully closed.";
}
?>
The above example will output:
Connection was successfully closed.
