Dear EDI Gurus,
We came across an production issue and I believe this is the forum when I can
get some ideas to fix. we use Expedite Base/MVS to connect to our VAN. We
have been experiencing Mainframe job abends due to connectivity issues. When
investigated we found that two EDI jobs are trying to access IBM0RELY( IELUNAME
for Information exchanage is IBM0RELY) simultaneously. When one job is
executing/accessing IBM0RELY, second job abends trying to access IBM0RELY. As
a result of this, we have been getting EDI job abends once in a while.
The IELUNAME(IBM0RELY) is the LU that EB/MVS wants to establish a connection
with. EB/MVS has an LU on the local system in order to establish that
connection. The USERLUNAME parameter is the list of LU names that EB/MVS
uses. Internally, EB/MVS selects the first one and issues an ENQ on the name
first USERLUNAME with a scope of SYSTEMS before attempting to establish VTAM
connectivity using that LU name.
Right now our inpro file has(one job has USERLUNAME1 in the first place, second
job has USERLUNAME2 in the first place)
SNACOMM
IELUNAME(IBM0RELY)
USERLUNAME(USERLUNAME1)
USERLUNAME(USERLUNAME2)
USERLUNAME(USERLUNAME3)
USERLUNAME(USERLUNAME4)
USERLUNAME(USERLUNAME5);
RETURN(00000);
TRANSMIT
AUTOSTART(N)
TIMEOUT(10)
AUTOEND(N);
RETURN(00000);
PROFILERC(00000);
When asked our VAN provider about this, they suggested to use ENQ with below
tables.
QNAME RNAME SCOPE Description
**LOCK** Luname SYSTEMS Prevent simultaneous use of the “userlunames”
INFOEXCH Account UserID SYSTEMS Prevent simultaneous Information Exchange
sessions starting for “Account UserID”
can anyone suggest how to go about this? any examples are greatly appreciated.
thanks in advance.
regards
Vasanth
