Component Symbol Comment
proud Represents the data area required for each user
running OpenEdge. 1 2 This value varies greatly,
depending on the application you run and whether
you use the compiler. It is also affected by many of the
startup parameters. For single-user clients, the
parameters are:
• Blocks in Database Buffers (-B)
• Directory Size (-D)
• Stack Size (-s).
For multi-user clients, the parameters are:
• Directory Size (-D)
• Stack Size (-s)
• Maximum Memory (-mmax)
psd Represents the data area required for each database
server serving remote clients. (Not used for
single-user or multi-user clients if the users are
self-service). This space is used for communication
buffers and other server memory requirements.
pbd Represents the data area required by each database
broker. (One database broker is required for each
different database simultaneously in use in multi-user
mode whether you are using remote client/servers,
self-service, or both.) This value is determined by the
values of startup parameters 2 that consume memory,
including:
• Database Buffers (-B)
• Lock-table Entries (-L)
• Number of Users (-n).
Note: Each increment of -n increases pbd by 2K.
1. Use the UNIX size command to determine the exact size. See Table 30 to determine the approximate
value.
2. See OpenEdge Deployment: Startup Command and Parameter Reference for
information about OpenEdge startup parameters.
