Fm 16.3 Patch Download
In recent months we saw several customers with large investments into Hana technologies approach Microsoft for information about deploying large mission critical SAP applications on Azure with the Sybase ASE database.
FM Lovers, A small update is available now for #FM16 — Football Manager (@FootballManager) July 21, 2016 Sesuai tweet dari @FootballManager.
SAP Hana customers are typically able to deploy Sybase ASE at little or no additional cost if they have licensed Hana Database.
Many of the customers that have contacted Microsoft are shutting datacenters or terminating UNIX platforms and moving ECC or BW systems in the size range of 25-45TB DB volume to Azure. An earlier blog describes some of the requirements and best practices for VLDB migrations to Azure. https://blogs. msdn. microsoft. com/saponsqlserver/2018/04/10/very-large-database-migration-to-azure-recommendations-guidance-to-partners/
Until recently there was no simple documented straight forward installation procedure for a typical two node High-Availability pair with Synchronous replication and a third node with Asynchronous replication. This is quite a common requirement for SAP customers.
This blog is designed to supplement the existing SAP provided documentation and to provide some hints and additional information. The SAP Sybase team are continuously updating and improving the Sybase documentation, so it is always recommended to start with the official documentation and then cross reference this documentation. This document is based on real deployments from Cognizant and DXC. The latest version of Sybase & Suse were then installed in a lab test environment to provide screenshots
The high-level installation process for a 3 tier SAP Distributed Installation is:
- Read required OSS Notes, Installation Guides, Download Installation Media and the SAP on Sybase Business Suite documentation
- For SUSE Linux Release 12 with SP3 release note : https://www. suse. com/releasenotes/x86_64/SUSE-SLES/12-SP3/
- SAP Software Downloads https://support. sap. com/en/my-support/software-downloads. html
- Sybase Release Matrixhttps://wiki. scn. sap. com/wiki/display/SYBASE/Targeted+ASE+16. 0+Release+Schedule+and+CR+list+Information
- Sybase Official Documentation https://help. sap. com/viewer/product/SAP_ASE/16. 0. 3. 3/en-US
- Provision Azure VMs with Suse for SAP Applications 12. 3 with Accelerated Networking Enabled
- Perform OS patching and preparation steps detailed below
- Run SWPM Distributed Install and install the ASCS Instance
- Export the /sapmnt NFS share
- Mount the /sapmnt NFS share on the Primary, Secondary and DR DB server
- Run SWPM Distributed Install and install the Primary DB Instance
- Run SWPM Distributed Install and install the Primary Application Server (Optional: add additional App servers)
- Perform Sybase Always-on preparation steps on Primary DB Instance
- Run setuphadr on Primary DB Instance
- Run SWPM Distributed Install and install the Secondary DB Instance
- Perform Sybase Always-on preparation steps on Secondary DB Instance
- Run setuphadr on Secondary DB Instance
- Run SWPM Distributed Install and install the DR DB Instance
- Perform Sybase Always-on preparation steps on DR DB Instance
- Run setuphadr on DR DB Instance
- Run post steps such as installing Fault Manager
- Suse 12. 3 with latest updates
- Sybase 16. 03. 03
- SWPM version 22 or 23. SAP Kernel 7. 49 patch 500. NetWeaver ABAP 7. 50
- Azure Ev3 VMs with Accelerated Networking and 4 vcpu
- Premium Storage – each DB server has 2 x P20 disks (or more as required). App server has only a boot disk
- Official Sybase Documentation (some steps do not work, supplement with this blog) https://help. sap. com/viewer/product/SAP_ASE/16. 0. 3. 3/en-US
- Sample Response Files are attached here: Sybase-Sample-Response-Files. It is recommended to download and review these files
- Sybase Always-on does not leverage OS level clustering technologies such as Pacemaker or Windows cluster. The Azure ILB is not used. Instead the SAP workprocess is aware of the Primary and Secondary Sybase server. The DR node does not support automatic failover and this is a manual process to setup and configure SAP app servers to connect to the DR node
- This installation shows a “Distributed” installation. If the SAP Central Services should be highly available, follow the SAP on Azure documentation for Pacemaker
- Sybase Fault Manager is automatically installed on the SAP PAS during installation
- Be careful of Linux vs. Windows End of Life characters. Use Linux command cat -v response_file. rsIf ^M are seen then there are Windows EOL characters.
Example:cat -v test. sh
Output:
Line 1 ^M
Line 2 ^M
Line 3 ^M
(Note: CTRL+M is a single character in Linux, which is carriagereturn in Windows. This needs to be fixed before utilizing the file in Linux )
To fix the issue
$> dos2unix test. sh
Output
Line 1
Line 2
Line 3
Example: <IP Address><FQDN> <SHORTNAME> <#Optional Comments>

Common Prepare Steps on all Suse Servers
sudo zypper install -y glibc-32bit
sudo zypper install -y libgcc_s1-32bit
#these two glib 32bit are mandatory otherwise Always-on will not work
sudo zypper up -y
Note : It is mandatory to reboot the server if kernel patches are applied.
#resize the boot disk. The default linux root disk of 30GB is too small. Shutdown the VM and edit the disks in Azure Portal or Powershell. Increase the size of the disk to 60-100GB. Restart the VM and run the commands below. There is no benefit or advantage to provisioning an additional separate disk for a SAP application server
sudo fdisk /dev/sda
##delete the existing partition (this will not delete the data) and create [n] new primary [p] partition with defaults and write [w] config
sudo resize2fs /dev/sda2
sudo reboot
#Check Accelerated Networking is working
/sbin/ethtool -S eth0 | grep vf_
#Add these entries to the hosts file
sudo vi /etc/hosts

#edit the waagent to create a swapfile
sudo vi /etc/waagent. conf
line to look for>>
ResourceDisk. EnableSwap=n
ResourceDisk. SwapSizeMB=
<<
Modify the above values Note : Swap size must be given in MB size only.
#enable the swapfile and set a size of 2GB or more. Example:
ResourceDisk. EnableSwap=y
ResourceDisk. SwapSizeMB=2000
Once done restart of the agent is necessary to get the swap file up and active.
sudo systemctl restart waagent
Other Services to be enabled and restarted are:
sudo systemctl restart nfs-server
sudo systemctl enable nfs-server
sudo systemctl status uuidd
sudo systemctl enable uuidd
sudo systemctl start uuidd

#create disks for sybase
sudo fdisk -l | grep /dev/sd
sudo fdisk /dev/sdc -> n, p, w
sudo fdisk /dev/sdd -> n, p, w
#It is generally recommended to use LVM and create pv, lv etc here so we can test performance later with striping additional disks.
Note: if multiple disk used in creating data / Backup / Log storage, make a necessary striping enabled to get optimal performance.
Example:
vgcreate VG_DATA /dev/sdc /dev/sdd
lvcreate -l 100%F VG_DATA -n lv_data -i 2 -I 256
sudo pvcreate /dev/sdc1 /dev/sdc1

I understand that there needs to be a hierarchy of power to the weapons but in vanilla, there aren't many weapons that are actually used during endgame. The patch buffs the weapons that were by all accounts and purposes useless once you hit Lvl.72, opening up many different playstyles. Originally posted by:I would've preferred something that nefed as much as it buffed in order to make BL2 a bit more challenging.I've never understood the idea of nerfing weapons in a PvE game.

Patch 2.1, aka “Niven”, was released on 2018-05-22 with the checksum 01a9.The patch was released alongside the Distant Stars story pack. C O D E X P R E S E N T S Stellaris – Update v1.2.1 Hotfix. New additions are going to be in 2.1.3. More of those until there's a named stable patch (2.2?), in September or October. Only if they broke something horribly will there be a fast hotfix, which would be 2.1.3. That would make likely next bugfix to be 2.1.4. Please note this is an opt-in patch. You have to choose to activate it. Steam library -> Right click on Stellaris -> Properties -> Betas tab -> choose '2.1.2_beta'. Stellaris 2.1.2 patch download torrent.

1. Install the DB host using SWPM in the same way as the companion host
2. Copy the companion host response file 4v4 mugen patch download.
3. Duplicate the section with all the COMP entries and add it at the bottom and rename at section of the newly copied COMPs to DR (for example). Leave the old COMP and PRIM entries as is.
4. Change the setup site to DR
5. All other entries from PRIM and COMP must remain the same since the setuphadr run for 3rd node needs to know about previous 2 hosts.
6. Execute setuphadr

Note: mount points are visible only when the folders are accessed in df –h command when auto mount is enabled.
##create a directory for the source files.
sudo mkdir -p /sybase/source
## copy source files
sudo chmod 777 /sybase/source -R
## setup automount for /sapmnt
### – use auto mount not the “old” way sudo mount -t nfs4 -o rw sybapp1:/sapmnt /sapmnt
sudo mkdir /sapmnt
sudo vi /etc/auto.master
# Add the following line to the file, save and exit
+auto.master
/- /etc/auto.direct
sudo vi /etc/auto.direct
# Add the following lines to the file, save and exit
/sapmnt -nfsvers=4,nosymlink,sync sybapp1:/sapmnt
sudo systemctl enable autofs
sudo service autofs restart
sudo /sybase/source/swpm/sapinst SAPINST_REMOTE_ACCESS_USER=<os-user>
Stop the autofs and unmount the /sapmnt – sapinst will continue
The /sapmnt must be mounted again shortly after

AlwaysOn Testing & Useful Command Syntax
In the section below planned and unplanned failovers as well as monitoring commands are used.
It is recommended to review the Sybase documentation and also to review these SAP Notes:
1982469 – SYB: Updating SAP ASE with saphostctrl
1959660 – SYB: Database Fault Management
2179305 – SYB: Usage of saphostctrl for SAP ASE and SAP Replication Server
## Check if Fault Manager is running on the SAP PAS with this command
ps -ef | grep sybdbfm
executable in /usr/sap/<SID>/ASCS00/work
sybdbfm is copied to sybdbfm. sap<SID>_ASCS00
cd /usr/sap/<SID>/ASCS00/work
. /sybdbfm. sapASE_ASCS00 status
. /sybdbfm. sapASE_ASCS00 hibernate
. /sybdbfm. sapASE_ASCS00 resume
login as syb<sid> in this case sybase
## Login to the RMA
isql -UDR_admin -P<<password>> -SASE_RMA_Site1 -I DM/interfaces -X -w999
## to see all the components that are running
sap_version all
go
## to see the status of a replication path
sap_status path
go
## to see the status of resources
sap_status resource
go
## Login to ASE
The syntax “-I DM/interfaces” does a lookup in the Sybase AlwaysOn configuration database to find the host and TCP port
isql -UDR_admin -P<<password>> -SASE_Site1 -I DM/interfaces -X-w999
## to clear down the transaction log run this command
dump tran ASE with truncate_only
go
## to show freespace in DB
sp_helpdb ASE
go
## Transaction log backups are needed on all replicas otherwise the Trans Log will become full
## to start/stop/get info on Sybase DB (and all required components for Always on like RMA) – run this on the DB host
sudo /usr/sap/hostctrl/exe/saphostctrl -user sapadm -function StartDatabase -dbname ASE -dbtype syb
sudo /usr/sap/hostctrl/exe/saphostctrl -user sapadm -function StartDatabase -dbname ASE_REP -dbtype syb
## to get Sybase DB status
sudo /usr/sap/hostctrl/exe/saphostctrl -user sapadm -function GetDatabaseStatus -dbname ASE -dbtype syb
## to get Sybase DB replication status
sudo /usr/sap/hostctrl/exe/saphostctrl -user sapadm -function LiveDatabaseUpdate -dbname ASE -dbtype syb -updatemethod Check -updateoption TASK=REPLICATION_STATUS
## to send a trace ticket logon to RMA and execute these commands
sap_send_trace Site1
go
sap_status active
go
## during HADR testing leave tail running on the file /usr/sap/<SID>/ASCS00/work
tail -100f dev_sybdbfm
## to force a shutdown of the DB engine run the command below. Always-on will try to stop a normal shutdown of the DB
shutdown with wait nowait_hadr
go
## to do a planned failover from Primary to Companion DB the normal sequence is:
1. Failover from Primary to Companion
2. Drain logs from Primary to the DR site
3. Reverse Replication Route to start synchronization from the new Primary to the Companion and DR
— There is a new command that does all these steps automatically:
/usr/sap/hostctrl/exe/saphostctrl -user sapadm – -function LiveDatabaseUpdate -dbname ASE -dbtype syb -updatemethod Execute -updateoption TASK=FAILOVER -updateoption FAILOVER_FORCE=1 -updateoption FAILOVER_TIME=300
## it is recommended to use this command. If there are errors check in the path /usr/sap/hostctrl/work for log files
##other useful commands:
## to disable/enable replication from a Site to all routes
sap_disable_replication Site1, <DB>
sap_enable_replication Site1,Site2,<DB>
## command to manually failover
sap_failover <primary>,<standby>,<timeout>, [force], [unplanned]
## Materialize is a “dump and load” to reinitialize Sybase Alwayson replica.
sap_materialize auto,Site1,Site2,master
sap_materialize auto,Site1,Site2,<SID>
Sybase How To & Links
Customers familiar with SQL Server AlwaysOn should note that although it is possible to take a DB or Log backup from a replica, these backups are not compatible between Primary <-> Replica databases. It is also a requirement to run transaction log backups on the replica nodes unlike SQL Server.
