Unix Virtual Memory Sizing | Compaq AA-Q88CE-TE manual

Starting and Setting Up RTR

2.8 RTR ACP Virtual Memory Sizing

Use of /LINK and /PROCESSES do not take into account memory requirements for transactions. If an application passes a large amount of data from client to server or vice-versa this should be included in the sizing calculations. For further information on the START RTR qualiﬁers see the START RTR command in the Command Reference section.

Once the requirements have been determined for the START RTR qualiﬁers of /PGFLQUOTA or /LINK and /PROCESSES then RTR should be started with these qualiﬁers set to ensure the appropriate virtual memory quotas are set.

Note

The AUTHORIZE utility of OpenVMS does not play a role in the determination of RTR ACP quotas. RTR uses AUTHORIZE quotas for the command line interface and communication server, COMSERV. Virtual memory sizing for the RTR ACP are determined through the qualiﬁers of the START RTR command.

2.8.2 UNIX Virtual Memory Sizing

The RTR ACP process requires the operator to size the process limits for the ACP before starting RTR on all platforms. No direct control of the process quotas of the RTR ACP is offered for UNIX based platforms but log ﬁle entries will result if hard limits are found to be less than the preferred values for the RTR ACP.

The following are the minimum limits for the ACP on the following UNIX platforms:

•On Compaq Tru64 UNIX:

A minimum of 1024 open ﬁle descriptors

A minimum of 1073742 Kbytes for virtual memory address space

A minimum of 268436 Kbytes for a single ﬁle size

A minimum of 419430 Kbytes for heap data segment sizing

A minimum of 33555 Kbytes for core ﬁle size

A minimum of 8389 Kbytes for stack segment size

A minimum of 0 for CPU time

•On Sun Solaris:

A minimum of 256 open ﬁle descriptors

A minimum of 1073742 Kbytes for virtual memory address space

A minimum of 268436 Kbytes for a single ﬁle size

A minimum of 419430 Kbytes for heap data segment sizing

A minimum of 33555 Kbytes for core ﬁle size

A minimum of 8389 Kbytes for stack segment size

A minimum of 0 for CPU time

•On IBM AIX:

A minimum of 268436 Kbytes for a single ﬁle size
