Scan log file for errors
Hi everyone.
I am still new to UNIX, and am having trouble figuring out how to create a script to scan a log file to look for errors based on a string.
We run AIX 5.3, and would like the ability to report all the instances of WebSphere Broker Execution groups crashing. This script would ideally exit with a status of 1 and list the Execution Group names that had crashed if an error was detected. This would then allow our scheduling tool to report the error back to the user.
An example of the error we would be scanning for is contained below:
Quote:
Oct 22 10:01:53 <server-name> user:warn|warning WebSphere Broker v60011[999480]: (BRK_MQCSPA01)[4370]BIP2060W: The broker has detected that the
Execution Group EXG_CS06, process ID 1048594, has shutdown. : BRK_MQCSPA01.agent: /build/S600_P/src/AdminAgent/ImbAdminAgent.cpp: 4296: ImbA
dminAgent::startAndMonitorADataFlowEngine: :
Any help with this would be greatly appreciated.

lb_lookup_type
lb_lookup_type(3ncs) lb_lookup_type(3ncs)
Name
lb_lookup_type - look up information about a type in the Global Location Broker database
Syntax
#include <idl/c/lb.h>
void lb_$lookup_type(obj_type, lookup_handle, max_num_results, num_results, results, status)
uuid_$t *obj_type;
lb_$lookup_handle_t *lookup_handle;
unsigned long max_num_results;
unsigned long *num_results;
lb_$entry_t results[ ];
status_$t *status;
Arguments
obj_type The UUID of the type being looked up.
lookup_handle A location in the database. On input, the lookup_handle indicates the location in the database where the search
begins. An input value of lb_$default_lookup_handle specifies that the search will start at the beginning of the data-
base. On return, the lookup_handle indicates the next unsearched part of the database (that is, the point at which the
next search should begin). A return value of lb_$default_lookup_handle indicates that the search reached the end of
the database; any other return value indicates that the search found at most max_num_results matching entries before it
reached the end of the database.
max_num_results The maximum number of entries that can be returned by a single routine. This should be the number of elements in the
results array.
num_results The number of entries that were returned in the results array.
results An array that contains the matching GLB database entries, up to the number specified by the max_num_results parameter.
If the array contains any entries for servers on the local network, those entries appear first.
status The completion status. If the completion status returned in is equal to status_$ok , then the routine that supplied it
was successful.
Description
The routine returns GLB database entries whose obj_type fields match the specified type. It returns information about all objects of that
type and about all interfaces to each of these objects.
The routine cannot return more than max_num_results matching entries at a time. The lookup_handle parameter enables you to find all match-
ing entries by doing sequential lookups.
If you use a sequence of lookup routines to find entries in the database, it is possible that the returned results will skip or duplicate
entries. This is because the Location Broker does not prevent modification of the database between lookups, and such modification can
change the locations of entries relative to a lookup_handle value.
It is also possible that the results of a single lookup routine will skip or duplicate entries. This can occur if the size of the results
exceeds the size of an RPC packet (64K bytes).
Examples
The following statement looks up information in the GLB database about the type array :
lb_$lookup_type (&array_id, &lookup_handle, max_results,
&num_results, &results, &status);
Diagnostics
This section lists status codes for errors returned by this routine in
lb_$database_invalid
The format of the Location Broker database is out of date. The database may have been created by an old version of the
Location Broker; in this case, delete the out-of-date database and reregister any entries that it contained. The LLB
or GLB that was accessed may be running out-of-date software; in this case, update all Location Brokers to the current
software version.
lb_$database_busy The Location Broker database is currently in use in an incompatible manner.
lb_$not_registered The Location Broker does not have any entries that match the criteria specified in the lookup or unregister routine.
The requested object, type, interface, or combination thereof is not registered in the specified database. If you are
using an or routine specifying an LLB, check that you have specified the correct LLB.
lb_$cant_access The Location Broker cannot access the database. Among the possible reasons:
1. The database does not exist, and the Location Broker cannot create it.
2. The database exists, but the Location Broker cannot access it.
3. The GLB entry table is full.
lb_$server_unavailable
The Location Broker Client Agent cannot reach the requested GLB or LLB. A communications failure occurred or the bro-
ker was not running.
