如何从具有依赖关系的一个批处理文件启动多个批处理文件？

Question

I want to run one batch file, that start the other batch files. I looked at a similar question posted here: How to run multiple .BAT files within a .BAT file

I followed the example (specifically the very last suggestion) and it worked...partially. It did launch the batch files that I needed to. However, in order for the applications to function properly, some of these batch files have to open, and then run their course for a few seconds, before the next the next batch file launches, otherwise they won't be registered. Specifically, the first batch file launches a web applications server (JBOSS 5.1), then the next batch file opens a pool manager, then the other two launch distribution servers. When I run my batch file that calls the others, they all launch nearly simultaneously, and they do not register each other. Can I even do this with a batch file? Or do I have to go into the code of the other batch files and make changes there? I want to avoid that at all costs.

Here is what I have so far:

start cmd /k CALL D:\jboss-5.1.0.GA-jdk6\jboss-5.1.0.GA\bin\run.bat

start cmd /k CALL batch1.bat

start cmd /k CALL batch2.bat

start cmd /k CALL batch3.bat

Answer 1

You can drop the start cmd /k and just use CALL .

CALL D:\jboss-5.1.0.GA-jdk6\jboss-5.1.0.GA\bin\run.bat
CALL batch1.bat
CALL batch2.bat
CALL batch3.bat

Answer 2

Answer:

Add the /wait option to the start command.

WAIT        Start application and wait for it to terminate.

Example:

start /wait cmd /k CALL D:\jboss-5.1.0.GA-jdk6\jboss-5.1.0.GA\bin\run.bat

start /wait cmd /k CALL batch1.bat

start /wait cmd /k CALL batch2.bat

start /wait cmd /k CALL batch3.bat

Otherwise just use a ping delay between the starts. (See user706837's Answer)

Answer 3

Whenever I have batch files that depend on another I either: 1. nest them; meaning, if batch1 needs to run before batch2, then I add batch2 within batch1. 2. put a 'sleep' call within batch2. This is only possible if you are fairly certain of the startup duration for batch1.

A sample sleep command is:

ping 127.0.0.1 -n 4 > null

This will make the batch file wait for 3 seconds. (Because there are only 3, 1 second sleeps, between each of the 4 echos)

Examples:

start cmd /k CALL D:\jboss-5.1.0.GA-jdk6\jboss-5.1.0.GA\bin\run.bat
ping 127.0.0.1 -n 4 > null
start cmd /k CALL batch1.bat
ping 127.0.0.1 -n 4 > null
start cmd /k CALL batch2.bat
ping 127.0.0.1 -n 4 > null
start cmd /k CALL batch3.bat

Answer 4

There are multiple ways for that.

1.

rem echo call A

CALL a.bat

rem echo call B

CALL b.bat

rem echo call C

CALL c.bat

rem pause

--------------------

2.

echo call A

start cmd /k CALL a.bat


echo call B

start cmd /k CALL b.bat

echo call C

start cmd /k CALL c.bat

pause

---------------------

Here the difference is-

start cmd /k

   It creates these many instances. So we can see multiple number of CMD prompts.


CALL

   Each descendent CALL waits for the completion of the previous CALL.
