Hi to All, we want to thanks in advance for all your comments & recomendations about this concern. sorry for the delay for feedback B)), next are some questions.

The ISVIEW file sent corresponds to a normal load for around 250 concurrent users but this does not mean an overload at all. In fact we have about 2 weeks every 4 months that are critical and presents slow downs due about 380 concurrent users and high process demand, at these moments we have observed more than 2500 files opened at once, this is reported by the corresponding ISVIEW file.

SL_SPIN was setted to such number for 2 reasons: 1) Was a Local Support recommendation and, 2) Was a result after large test sessions. So, we donĀ“t find how to set this value in accordance our server configuration: number of processors & memory. Is there any documentation that help us to solve this ?

The SHMSIZE parameter is deducted by the other 4 parameters. Do you recommend to set this to a fixed value?

We use PRO-ISAM files for small size ones & C-ISAM files for larger than 1GB. Really Oracle is used since jan 2004, but is used for interface purposes.

We have constantly session tests to reproduce overloading, these runs pasts 10:00 PM. The first test runs with 350 concurrent users ending with a duration of 12 minutes, then we kill the ISCOLLECT processs without restart the server. The second test with the same number of users longs 5 minutes, can you tell me why this happens?

Can you tell us where to set the TRACEALL & TIMESTAMP parameters?

At this moment we are unable to upgrade our PRO-IV 4.6 version.

To kill the ISCOLLECT process, we log off all users then kill the process without restart the system. This task longs 1 to 2 minutes. These week we have done this process 5 times in working time.

Please, we need some feedback concerning to interpret correctly de ISVIEW file contents. Can you help us?

- isamdef Contents next:

MAXFILES = 3000 max # of open isam files

MAXUSERS = 400 max # users in system
USRFILES = 200 max # open files per user

MAXLOCKS = 250 max # of simultaneous rcd locks
AVGLOCK = 120 average size (bytes) of a record lock

#SHMSIZE = 3145728 shared memory size (alternate to above 4 parms)
# (assuming (dev_t == 2) and (pid_t == 4))
# SHMDELAY = 5 time to wait for a resource (seconds)
#SHMRETRY = 30 max # of attempts at resource

SL_SPIN = 1000
SL_NAP = 10

The value for SHMSIZE is 2MB in accordance from parameters in isamdef file

- isview171104 This file is the output from the isview command and is some long, see attached file.

We don't know how interpret content from this file, we have asked to our local support too without success. can you help us to determine the kind of errors or warnings, meannings, docs, etc?

- In general, our site has the next characteristics:
