Installing Adaptive Server Using the Binary Overlay

Use the installer to install Adaptive Server version 15.7 SP100 on top of your existing Adaptive Server, if it is no earlier than version 15.x.

From your SYBASE directory, shut down the servers that are using the binaries. Use a regular "polite" shutdown as opposed to using the shutdown with nowait option, both as the initial and final steps. Doing so flushes free space accounting figures, object statistics, and runs checkpoint on the database to minimize recovery work during the upgrade process.
Use the installer to load the new software from the CD or DVD.

Navigate to the CD or DVD drive and enter ./setup.bin.
Select the language.
On the Introduction screen, click Next.
Specify the destination directory with the Adaptive Server you want to update, then click Next.

Note: Do not use single or double quotes character when specifying a path. The installer does not recognize quote marks, and displays an error.
If you see Choose Update Installation, this means that there is an older version of Adaptive Server in the directory you specified for the installation.
If you click:
- Yes – the installer identifies which features you already have, and automatically updates them to the newest version.
- No – the installer prompts you to perform a typical, full, or custom installation to specify what features you want to update.
Note: Clicking No does not take you to the previous screen to change the installation directory. To do this, click Previous.
Click Next.
The installer checks that the version you wish to update is compatible with the version of Adaptive Server you are installing. If the version is incompatible, the Check Upgrade Incompatible Version dialog appears, and you see a message similar to:
```
Warning: The current "Sybase Adaptive Server Enterprise Suite" 
in your destination directory is not compatible with this version upgrade; 
some bug fixes may be unavailable if you proceed. See the release note for 
more information.
```
You may see a similar message if your Adaptive Server is an out-of-band release, such as an emergency bug fix, one-off, controlled, or instrumental release:
```
Warning: The current "Sybase Adaptive Server Enterprise Suite" 
in your destination directory is an out-of-band release; some bug fixes 
may be unavailable if you proceed. Verify that the bug fixes you need are 
in this newer version before proceeding with the upgrade.
```
If you see such messages, click Cancel to stop the installation process. To override the error and continue with the installation, select Proceed installation with incompatible version and click Next.

Warning! Upgrading to an incompatible version may cause software regression. SAP recommends that you cancel the installation and obtain a compatible version of Adaptive Server.
If you perform the installation in a silent, or unattended mode, and the versions are incompatible, the installer asks you to rerun the installer with this argument, then quit:
```
DALLOW_UPGRADE_TO_INCOMPATIBLE_VERSION=true
```
Install Adaptive Server 15.7 SP100 into the existing $SYBASE installation path.

If you are upgrading from Adaptive Server version 15.7.x, once the installer unloads the files, the installer displays the Choose Update Adaptive Server dialog, which installs and updates Adaptive Server, system stored procedures, and messages. If you select Update Adaptive Server, the installer prompts you to select your Adaptive Server, and enter the system administrator password.
Run select @@version. The server should now be at version 15.7 SP100.
