Control not returning to UNIX when sqlplus is executed in while loop of shell script
Hi All,
I have observed some of the scripts gets stuck because sqlplus session is not completing it's session. This behavior is intermittent. I will give one of the scenario. Below is the code which executes one sql query.
below is the unix session.
pwlm 8297 8290 0 00:16 ? 00:00:03 /bin/ksh -a /opt/XWLMLL02
pwlm 29121 8297 0 00:32 ? 00:00:00 sqlplus -s
The script has run a process internally and above code part is to monitor whether the process is completed. Even though the process is completed, the script has not moved further from this point. Upon checking further, I have seen one active sqlplus session. I suspect that the sqlplus session is from the above code and it is somehow stuck in turn the script has stuck.
I have observed this similar issue 3 times till now in the past 7 days. But, it is for different scripts. The logic remains the same.
This script was working fine in our old infrastructure where there was AIX server. We have not at all faced this issue over there.
Anyone, could help me to resolve the issue?
Thanks in Advance.

LEARN ABOUT PHP
oci_set_module_name
OCI_SET_MODULE_NAME(3)OCI_SET_MODULE_NAME(3)oci_set_module_name - Sets the module nameSYNOPSIS
bool oci_set_module_name (resource $connection, string $module_name)
DESCRIPTION
Sets the module name for Oracle tracing.
The module name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement
is executed.
The name can subsequently be queried from database administration views such as V$SESSION. It can be used for tracing and monitoring such
as with V$SQLAREA and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE.
The value may be retained across persistent connections.
PARAMETERS
o $connection
-An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).
o $module_name
- User chosen string up to 48 bytes long.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
NOTES
Note
Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards.
Tip
Performance
With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack-
age. This is less efficient than using oci_set_client_info(3).
Caution
Roundtrip Gotcha
Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is
enabled.
EXAMPLES
Example #1
Setting the module name
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the module
oci_set_module_name($c, 'Home Page');
// Code that causes a roundtrip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the
// modules in use:
sqlplus system/welcome
SQL> select module from v$session;
