‘Preparing the SAPinst Inst.’: Released JDK versions
In section ‘Preparing the SAPinst Installation’, the listed path to information about released JDK versions in SAP Service Marketplace is no longer correct. Instead, you can find released JDK versions on SAP Service Marketplace as follows:
1. Go to http://service.sap.com/pam2. On the right-hand panel, choose SAP NETWEAVER –> SAP NetWeaver components (before SAP NW 04) –> SAP Web AS 6.203. Choose tab strip ‘JSE Platforms’
=======================================================================
1 AIX
————————
AIX only: Error message “PASSWORD EXPIRED”
Symptom:
After a new user has been created or a user password has been set the users password has expired immediately. This causes an error message “PASSWORD EXPIRED” to come up during the installation.
Prerequisites:
This happens only on AIX if the maximum password age (maxage) attribute for the user has a value different from 0.
Details:
The installation sets the timestamp for the last password change to 1970-01-01, 00:00 Coordinated Universal Time when it sets the password. This causes the password to have expired immediately if the maxage attribute is not 0 (which means that the password does not expire at all).
Solution:
Set the maximum password age (maxage) attribute of each user the installation creates to 0 as soon as the user has been created. This can be done using ’smit’.
————————
AIX 5.3: SAP system installation on raw devices If you are planning to set up your SAP systems on raw devices, you must also install the following APARs on top of AIX 5.3:
Apar: IY65454Apar: IY63076
Both APARs will be part of AIX 5.3 ML1 and higher.
Possible problems during change of AIX user attributes:
Before starting your SAP installation, please verify, that the file /etc/security/user has the following permissions:
-rw-r—– (and is owned by user “root” and group “security”).
In case you need to change this, use chmod 0640 /etc/security/user.
————————
AIX: Installation on AIX 5.3 – adapt /etc/services file
Customers trying to install SAP products on AIX 5.3 based systems (only complete fresh installs of AIX 5.3 are affected; systems, that were migrated form older AIX releases to AIX 5.3 will not see these problems)should edit /etc/services before they start the installation of the SAP product.
For the first time in AIX history AIX 5.3 comes with a “complete” /etc/services file, containing all entries of all registered services. Unfortunately SAP services collide with services of other software products.
To make sure, that SAPINST does not run into errors, you have to commentout all entries in /etc/services, that collide with the general SAP ports before starting SAPINST. If installing SAP instance with instance number xx, customers should comment out the entries refering to the following ports:
- 32xx
- 33xx
- 36xx
- 48xx
In case customers forgot to comment out the entries, SAPINST will run into an error, complaining about “port already in use”. In this case, customers can open another window, edit /etc/services as described above, save the file and just “Retry” the SAPINST step, that failed. Installation will then continue without any problem.

Max. JVM Heap Size for AIX JDK 1.3.1
How to increase the maximum java heap size above 1GB
Symptom:
Need larger JVM heap size, or Java Out of Memory Error on AIX JDK 1.3.1
Solution:
See related SAP Notes 667711 and 667841.
————————
Problem establishing new connections socket on AIX
Symptom:
This problem may manifest itself in a
variety of places in an R/3 environment. Typically, existing connections will continue to function,but new connections will fail e.g the message server may cease to accept new connections and preventing new logins via logon groups.
Solution:
See related SAP Note 646246.
————————
AIX: Script to prevent file/directory name conversion
For the operating IBM AIX, it has been noticed that an unwanted automatic conversion of all file and directory names on CDs occurs, changing all capital letters to small ones. Due to this conversion, the installation tool can no longer find the files required for the installation procedure.
SOLUTION:
Convert the file names and directory names to uppercase. To do this, use the following script:
CAUTION:
Do not copy SAP J2EE/Java CDs, as these CDs contain mixed-mode file names. Instead, perform the installation directly from these CDs.
#!/bin/sh
# Shell script to copy the CD to a target directory with uppercase
# letters.
echo “Mountpoint of CD? \c”; read CD
echo “Target Directory? \c”; read DIR
echo “Waiting ….”
# Activate the following line to see the commands excecuted
set -x
cd $CD
cp -r * $DIR
cd $DIR
chmod -R 777 *
cd $DIR
for j in `find $DIR -type d -depth -print`
do
cd $j
for i in `ls`
do
mv $i `echo $i | tr “[a-z]” “[A-Z]“`
done
done
set +x
Enter the complete path name of the CDs (for example /sapcd1) for the mountpoint and likewise enter the complete path name for the target directory.
Afterwards, you can use the directory as a “mountpoint” for the corresponding CD.
CAUTION – AIX 5L with Oracle 9.2.x only:
After you have copied the SAP Kernel CD, rename the file ORAVOLATILEDATABASEPARAMETERS.XML to OraVolatileDatabaseParameters.xml if it exists in the directory / on the CD.
————————
AIX: Restriction to AIX 5.1 not necessarily valid
The restriction contained in the documentation in section ‘AIX: OS OS-Dependent Installation Steps’ is not valid for all SAP components based on SAP Web AS 6.20. To check what OS version is released for your SAP component, see SAP Service Marketplace at:
http://service.sap.com/platforms
————————
AIX: Requirements Checklist: Wrong section for JDK (added w/ 1.05)
In the documentation in section ‘AIX: Requirements Checklist’, ignore the section ‘The SAP J2EE Engine and the … as described in this section.’.
————————
AIX: Creating UNIX Groups and Users
If using large file enabled filesystems, the field Soft FILE size should be set to -1 (unlimited).
————————
AIX: Memory larger than 2 GB on AIX
See the following SAP Notes for more information concerning the configuration of AIX hosts for R/3:
146528 Configuration of R/3 hosts with much RAM
95260 Many shared memories possible as of AIX 4.2.1
95454 A lot of extended memory on AIX
128935 AIX 4.3, large memory configuration
————————
AIX: C Set ++ for AIX Application Runtime, version >= 5.0.2.0 required
Before the installation:
Check if the C Set ++ is installed with the command:
lslpp -l xlC.rte
If the C Set ++ is not installed or is not of version 5.0.2.0 or
higher, download it from the IBM AIX Fix Distribution WWW sites in
your country, or from the USA site
http://techsupport.services.ibm.com/rs6k/fixdb.html
and install it by using smit (-> Software) as user root.
If you also need the base level fileset (xlC.rte.5.0.0.0), go to ftp://ftp.software.ibm.com/aix/products/ccpp/
and download vacpp5_runtime.tar.Z.
————————
After the installation, correct the path in .login
Problem: On AIX, .login is executed after .cshrc when a user logs on.
Therefore, the path from .cshrc is overwritten and SAP tools
that are located in the exe directory are not found.
Solution: For all users that have been created during the installation
(
adding $path:
before: set path = ( /usr/bin …
after: set path = ( $path /usr/bin …
————————
AIX with PowerPC 604 only:
Time specifications may be incorrect.
Before the installation, please apply Note 66479.
————————
Only AIX on RS 6000 SP:
If the centralized administration facility of an SP is active, users should be created on the control workstation and not on the nodes holding the instances.

5 HP-UX
———————–<,D039715 02/APR/2004>————————-
HP-UX: maxssiz_64bit 8.388.608 (new value in OS dependencies guide for Web AS 6.20)
Section: HP-UX: Checking and Modifying the UNIX Kernel :
New entry in parameter table:
Process Management | maxssiz_64bit| Max.user-stack segment size in bytes
| 8.388.608
———————–
HP-UX 10.20, 11.X : Error message “File name too long” when accessing files on CDROM
Solution:
Probably the CD contains the Rock Ridge Extensions to ISO 9660, so it is
best to access it using the pfs_mount command. Details can be found in
the man pages of pfs_mount(1M), pfs_mountd(1M) and pfsd(1M).
This should work in the vast majority of cases:
# nohup pfs_mountd &
# nohup pfsd &
# pfs_mount -o soft /dev/dsk/c?t?d? (mountpoint)
———————–
HP-UX 64: Default OS installation does not create a few required X-library symbolic links:
Due to a known HP bug (Doc.id. KBRC00003627), the default HP-UX 64
operating system installation does not create a few required X-library
symbolic links. These links must be created manually before starting
the Oracle9i Release 2 installation. You must have superuser privileges
to run these commands.
$ su – root
$ cd /usr/lib
$ ln -s /usr/lib/libX11.3 libX11.sl
$ ln -s /usr/lib/libXIE.2 libXIE.sl
$ ln -s /usr/lib/libXext.3 libXext.sl

———————–
HP-UX: Kernel param. already larger than SAP proposal
If a kernel value is already larger than the one suggested under SAP Requirements, there is no reason to reduce it regarding the operation of your SAP system. To prevent a reduction in SAP application performance, it is nevertheless recommended to analyse the exact meaning of such a parameter (and, if required, to reduce the parameter). You can find information about HP-UX kernel parameters at: http://docs.hp.com/hpux/onlinedocs/939/KCParms/ KCparams.OverviewAll.html
———————–
