Installing ESDs

Use these general instructions to install SAP Sybase IQ maintenance releases.

Some steps may differ for simplex and multiplex servers. See the cover letter included with the ESD for release-specific instructions.

Do not run ALTER DATABASE UPGRADE. If you do not run this command, you can roll the binary back to the previous version. You must, however, roll the coordinator back first.

Do one of the following:

Server	Action
Simplex	Shut down the server.
Multiplex	Shut down the multiplex node. Upgrade the secondary multiplex nodes first, one node at a time. Upgrade the coordinator last. A multiplex can include nodes running different software versions.

Server

Action

Simplex

Shut down the server.

Multiplex

Shut down the multiplex node.

Upgrade the secondary multiplex nodes first, one node at a time. Upgrade the coordinator last. A multiplex can include nodes running different software versions.

For server shutdown instructions, see Administration: Database > Run Database Servers > Ways to Start and Stop Databases.

Install the ESD.
For installation options, see Installation and Configuration Guide > Server Installations > Installing Server Software.
From the command line, change to %IQDIR16%\bin64.
Check the server version string, by entering:
```
start_iq -v2
```
Restart the server or multiplex node.
