Any Additional Steps After Adding New RAM To Sever?
Hi All,
We have a server at a client site running AIX 5.3, which we just up the RAM to 32GB, from initially 16GB (if I'm not mistaken).
This server is our Application server running J2EE applications on top of Oracle Internet Application Server. Recently we encountered one of the batch jobs hitting out of memory error.
From NMON I see that on average, there's 5GB of free memory available. %MAXPERM is set to '15' and %MINPERM is '5'. lru_file_repage is '0'. %comp is around '70' and %numperm is '15'.
I would like to ask
a) after adding real memory to the server, is there any additional changes we need to do to the VMO?
b) is the %MAXPERM too low?
Thanks.

TALAGENT(8) BSD System Manager's Manual TALAGENT(8)
NAME
talagent -- helper agent for the Transparent App Lifecycle feature.
SYNOPSIS
talagent [command [arguments]]
DESCRIPTION
The talagent daemon provides services related to the Transparent App Lifecycle feature. talagent may also be run manually as a command line
tool to output information about persistent state.
The options are as follows:
-help
Outputs usage information.
-dump bundle_id_fragment
Outputs the persistent state of an application whose bundle ID contains the given fragment, case insensitive ("textedit" for example).
You may also pass a path directly to the app's persistent state directory, usually in ~/Library/Saved Application State.
-launch bundle_id
This launches an app (in this case, TextEdit) in a manner approximating how apps get launched at login. You can pass either a bundle ID
fragment or a path to an app. The app is maintained stopped until you hit return in the launching window (or until it receives SIGCONT).
This is the easiest way to test the login scenario without needing to log in.
-casinfo [ASN]
With no arguments, outputs summary information about all apps. With one argument (an ASN), outputs the CAS record for that app.
-memory_pressure
Simulates memory pressure, which may cause apps that support automatic termination to exit. This does not actually allocate any memory.
-refresh_encryption
Rotates the bitmap encryption key, and attempts to cross-encrypt all existing window bitmaps under the new key. This is done periodically
by talagent.
